(A) 3/40
(B) 1/24
(C) 1/12
(D) 5/24

Answers

Answer:[tex]\dfrac{5}{24}[/tex]

Step-by-step explanation:

Let [tex]r[/tex] be the rate at which Jaquez completes his test.

Let [tex]x[/tex] part of test be completed by Jaquez in [tex]t[/tex] hours.

Then,

[tex]x=rt[/tex]

Given that Jaquez completed 1/8 of his test in 3/5 hour.

So,[tex]\frac{1}{8}=r\times \frac{3}{5}[/tex]

[tex]r=\frac{5}{24}[/tex]

To know how much he completes in one hour,substitute [tex]1[/tex] in the above equation.

adam swam 1500m in 19 minutes. if swimming at a rate of 4.5km/h burns 600 calories, how many calories did adam burn

Answers

Adam burnt 631.6 calories approximately

Solution:

Given that, Adam swam 1500m in 19 minutes.  

If swimming at a rate of 4.5km/h burns 600 calories,  

we have to find how many calories did adam burn?

Now, let us find his rate of swimming

Distance travelled = speed rate x time taken

[tex]\begin{array}{l}{1500 \mathrm{m}=\text { rate } \times 19 \text { minutes }} \\\\ {1500 \times 1 \mathrm{m}=\text { rate } \times 19 \times 1 \text { minute }}\end{array}[/tex]

We know that 1 hour = 60 minutes and also 1 kilometer = 1000 meter

[tex]\begin{array}{l}{1500 \times \frac{1}{1000} \mathrm{km}=\text { rate } \times 19 \times \frac{1}{60} \text { hour }} \\\\ {\frac{1500}{1000}=r a t e \times \frac{19}{60}} \\\\ {\text { Rate }=\frac{60}{19} \times \frac{3}{2}} \\\\ {\text { Rate }=\frac{30}{19} \times 3} \\\\ {\text { Rate }=\frac{90}{19}=4.736 \mathrm{km} / \mathrm{h}}\end{array}[/tex]

Now, we know that, swimming at a rate of 4.5km/h burns 600 calories,

Let "n" be the calories burnt when adam swam 1500 meter in 19 minutes

[tex]\begin{array}{l}{4.5 \mathrm{km} / \mathrm{h} \rightarrow 600 \text { calories }} \\\\ {\text {Then, } 4.736 \mathrm{km} / \mathrm{h} \rightarrow \text { n calories. }}\end{array}[/tex]

Now, by criss cross multiplication method,

[tex]\begin{array}{l}{4.5 \times n=4.736 \times 600} \\\\ {\rightarrow 4.5 n=2842.1052} \\\\ {\rightarrow n=631.578}\end{array}[/tex]

Hence, adam burnt 631.6 calories approximately.

A cylindrical can is to hold 20[tex]\pi[/tex] cubic meters. the material for the top and bottom costs $10 per square meter, and material for the side costs $8 per square meter. fond the radius r and the height h of the most economical can i.e. such that the cost is minimal

Answers

Answer:

The cost of the can is minimal when r=2 m and h=5 m

Step-by-step explanation:

This is an optimization problem which will be solved by the use of derivatives

We must find an expression for the total cost of the cylindrical can and then find its dimensions to make the cost minimal

Let's picture a cylinder of radius r and height h. Its volume is computed as

[tex]V=\pi r^2h[/tex]

To make the lids we need two circle-shaped pieces of a material which costs $10 per square meter

The area of each lid is

[tex]A_l=\pi r^2[/tex]

The cost of both lids will be

[tex]C_l=(2)(10)(\pi r^2)=20\pi r^2[/tex]

The lateral side of the cylinder can be constructed with a rectangle of material which costs $8 per square meter

The rectangle has a height of h and a width equal to the length of the circumference

[tex]A_s=2\pi rh[/tex]

The cost of the side of the cylinder will be

[tex]C_s=16\pi rh[/tex]

The total cost of the can is

[tex]C=20\pi r^2+16\pi rh[/tex]

We know the volume of the can is [tex]20\pi[/tex] cubic meters

[tex]V=\pi r^2h=20\pi[/tex]

Isolating h we have

[tex]h=\frac{20}{r^2}[/tex]

Using this value into the total cost

[tex]C=20\pi r^2+16\pi r(\frac{20}{r^2})[/tex]

[tex]C=20\pi r^2+\frac{320\pi}{r}[/tex]

Differentiating with respect to r

[tex]C'=40\pi r-\frac{320\pi}{r^2}[/tex]

To find the critical point, we must set C'=0

[tex]40\pi r-\frac{320\pi}{r^2}=0[/tex]

Operating

[tex]40\pi r^3-320\pi=0[/tex]

Solving for r

[tex]r=\sqrt[3]{\frac{320\pi}{40\pi}}=\sqrt[3]{8}[/tex]

r=2

And since  

[tex]h=\frac{20}{r^2}=\frac{20}{2^2}[/tex]

h=5

Differentiating again we find

[tex]C''=40\pi +\frac{640\pi}{r^3}[/tex]

Which is always positive for r positive. It makes the critical point found a minimum

The cost of the can is minimal when r=2 m and h=5 m

Answers

J+S=24 and J=S+6 represents the relationship between ages.

John is 15 years old and Sally is 9 years old.

Step-by-step explanation:

Let,

John's age = J

Sally's age = S

According to given statement, the sum of their ages is 24;

[tex]J+S=24[/tex]    Eqn 1

John is 6 years older than Sally means we will add 6 in Sally's age;

[tex]J=S+6[/tex]     Eqn 2

Putting value of J from Eqn 2 in Eqn 1;

[tex](S+6)+S=24\\S+6+S=24\\2S=24-6\\2S=18[/tex]

Dividing both sides by 2

[tex]\frac{2S}{2}=\frac{18}{2}\\S=9[/tex]

Putting S=9 in Eqn 2

[tex]J=9+6\\J=15[/tex]

J+S=24 and J=S+6 represents the relationship between ages.

John is 15 years old and Sally is 9 years old.

From 10 names on a ballot, a committee of 4 will be elected to attend a political national convention. How many different committees are possible?

Answers

Answer:

Number of committees that are possible =210

Step-by-step explanation:

Total names in ballot = 10

Total members to be elected for the committee = 4

So, we need the number of different ways in which 4 names out of 10 can be elected for the committee.

To find the number of ways in which the committee can be elected, we use the combinations which is given as

[tex]aCb=\frac{a!}{(a-b)!b!}[/tex]

where [tex]a[/tex] represents total number of members and [tex]b[/tex] represents total number of members to be elected.

So, [tex]10C4=\frac{10!}{(10-4)!4!}[/tex]

[tex]10C4=\frac{10!}{6!4!}[/tex]

[tex]10C4=\frac{10\times9\times8\times7\times6\times5\times4\times3\times2\times1}{6\times5\times4\times3\times2\times1\times4\times3\times2\times1}[/tex]

[tex]10C4=\frac{10\times9\times8\times7}{4\times3\times2\times1}[/tex] [Canceling the common numbers]

[tex]10C4=210[/tex]

∴ Number of committees that are possible =210

Using the combinations formula, we will see that 210 different committees are possible.

How many different committees are possible?

Here we need to use the combinations function. It says that for a set of N elements, the number of different subsets of K elements (such that K is equal or smaller than N) that we can make is:

[tex]C(N, K) = \frac{N!}{(N - K)!*K!}[/tex]

In this case, we have N = 10 and K = 4, replacing that we will get:

[tex]N(10, 4) = \frac{10!}{(10 - 4)!*4!} = \frac{10!}{6!*4!} = \frac{10*9*8*7}{4*3*2} = 210[/tex]

This means that from 10 names, there are 210 different committees of 4 members that can be made.

Final answer:

The next number in the pattern 1,7,8,15,23,38,61 is 99. The pattern can be understood by calculating the differences between consecutive numbers, and observing a pattern in these differences.

Explanation:

Let's take a look at the pattern 1,7,8,15,23,38,61 closely. At every step, we're adding an increasing number to get to the next term in the sequence. From 1 to 7, we add 6. From 7 to 8, we add 1. From 8 to 15, we add 7, from 15 to 23, we add 8, from 23 to 38, we add 15 and from 38 to 61, we add 23.

The difference between these numbers (6, 1, 7, 8, 15, 23) reads as follows: 5, 6, 1, 7 and 8. So, the next difference could be 15 (continuing the pattern in the differences). So, the next term would be obtained by adding 15 to previous term's difference (23) and then adding that result to 61.

Finally, we calculate 61 + (23 + 15) = 61 + 38 = 99. So, the next number in this pattern should be 99.

Jeremy didn't pay his previous month's credit card bill in full. This month's bill shows a finance charge of $85.50. Jeremy calculates the average daily balance in the new bill to be $5,343.75 What is the monthly Pentage rate on the card?

A 1.6%

B. 1.92%

C 16%

D. 19.2%

Answers

Answer:

The monthly percentage rate would be 1.6%

Step-by-step explanation:

Given,

Finance charge = $ 85.50,

Amount of bill in this month  = $ 5,343.75,

Hence, the monthly rate of percentage

[tex]=\frac{\text{Finance charge}}{\text{Amount of bill}}\times 100[/tex]

[tex]=\frac{85.5}{5343.75}\times 100[/tex]

[tex]=\frac{8550}{5343.75}[/tex]

[tex]=\frac{855000}{534375}[/tex]

= 1.6 %

i.e. OPTION A would be correct.

The monthly percentage rate on Jeremy's credit card is [tex]\[ {1.6\%} \][/tex]. So option (a) is correct.

To determine the monthly percentage rate on Jeremy's credit card, follow these steps:

Step 1: Identify the Given Values

Finance charge: $85.50

Average daily balance: $5,343.75

Step 2: Understand the Formula

The following formula is used to determine the finance charge:

[tex]\[ \text{Finance Charge} = \text{Average Daily Balance} \times \text{Monthly Percentage Rate} \][/tex]

Step 3: Set Up the Equation

Let ( r ) represent the monthly percentage rate (in decimal form).

[tex]\[ 85.50 = 5343.75 \times r \][/tex]

Step 4: Solve for the Monthly Percentage Rate

The equation should be rearranged to find ( r ):

[tex]\[ r = \frac{85.50}{5343.75} \][/tex]

Step 5: Perform the Calculation

[tex]\[ r = \frac{85.50}{5343.75} \approx 0.016 \][/tex]

Step 6: Convert the Decimal to a Percentage

[tex]\[ \text{Monthly Percentage Rate} = 0.016 \times 100 = 1.6\% \][/tex]

Therefore, the monthly percentage rate on Jeremy's credit card is:

Step-by-step explanation:

let W represent the number of wins and let P represent the number of plays let T represent profit from each play. from the question, Marcelo played 3 times, this means 3P can represent the first equation He won 7 times, 7W can represent the second equation

Read more at Answer.Ya.Guru – https://answer.ya.guru/questions/5930426-marcelo-played-a-carnival-games-six-times-he-spent-three-tokens.html

Certainly! Marcelo played the carnival games six times, spending three tokens for each game and winning seven tokens from each. To find the total profit in tokens that Marcello made, we can create two different expressions:

1. The first method involves directly calculating the net tokens won over all the games:
  - We calculate the total tokens won by multiplying the number of tokens won per game (7) by the number of games played (6).
  - Then we calculate the total tokens spent by multiplying the number of tokens spent per game (3) by the number of games played (6).
  - Finally, we determine the total profit by subtracting the total tokens spent from the total tokens won.
  Using this method, the first expression to calculate the total profit (P_1) is:
  \[
  P_1 = (\text{Tokens won per game} \times \text{Games played}) - (\text{Tokens spent per game} \times \text{Games played})
  \]
  \[
  P_1 = (7 \times 6) - (3 \times 6)
  \]
  \[
  P_1 = 42 - 18
  \]
  \[
  P_1 = 24
  \]
  So, using this expression, Marcello's total profit is 24 tokens.
2. The second method is to calculate Marcello’s profit per game and then multiply that by the number of games played:
  - First, we find the profit per game by subtracting the number of tokens spent per game (3) from the number of tokens won per game (7).
  - Then we multiply the profit per game by the total number of games played (6) to find the total profit.
  Using this method, the second expression to calculate the total profit (P_2) is:
  \[
  P_2 = (\text{Profit per game}) \times \text{Games played}
  \]
  \[
  P_2 = (\text{Tokens won per game} - \text{Tokens spent per game}) \times \text{Games played}
  \]
  \[
  P_2 = (7 - 3) \times 6
  \]
  \[
  P_2 = 4 \times 6
  \]
  \[
  P_2 = 24
  \]
  So, using the second expression, Marcello's total profit is also 24 tokens.
In both scenarios, the profit that Marcello makes from playing the six games is 24 tokens. The first expression gives us a direct calculation of the total, while the second expression calculates the profit on a per-game basis and then accumulates it.

What is the value of x if e3x+6=8

Answers

Final answer:

To solve the equation e3x+6 = 8 for 'x', first take the natural logarithm of both sides (3x + 6 = ln(8)) to isolate 'x', resulting in x = (ln(8) - 6) / 3. If calculated, the approximate answer is x ≈ -0.307.

Explanation:

This question pertains to solving for unknown variable 'x' in an exponential equation. The equation provided is e3x+6 = 8. In solving for 'x', you must first rearrange the equation by taking the natural logarithm (ln) of both sides. This is because the inverse operation for the base of natural logarithm 'e' is natural logarithm 'ln'. Thus, you get 3x + 6 = ln(8). Afterwards, you subtract 6 from both sides and divide by 3 to get x = (ln(8) - 6) / 3. The numerical solution for this can be calculated with a scientific calculator, which yields x as roughly -0.307.

A television and DVD player cost a total of $1192 . The cost of the television is three times the cost of the DVD player. Find the cost of each item.

Answers

The cost of the television is $894, and the cost of the DVD player is $298.

Let's denote the cost of the DVD player as x dollars.

Since the cost of the television is three times the cost of the DVD player, we can express the cost of the television as 3x dollars.

According to the given information, the total cost of both items is $1192. Therefore, we can set up the following equation:

[tex]\[ x + 3x = 1192 \]Now, let's solve for \(x\):\[ 4x = 1192 \]\[ x = \frac{1192}{4} \]\[ x = 298 \][/tex]

Now that we have found the cost of the DVD player [tex](\(x = 298\) dollars)[/tex], we can find the cost of the television, which is three times the cost of the DVD player:

[tex]\[ \text{Cost of television} = 3 \times 298 = 894 \][/tex]

Ace Hardware sells boxes of wrench (100) and hammers ($300). Howard ordered 40 boxes of wrenches and hammers for $8400. How many boxes of each are in the order?

Answers

Answer:

Howard's order will contain 15 boxes of hammers and 39 boxes of wrenches.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Price of box of wrenches = US$ 100

Price of box of hammers = US$ 300

Cost of the order = US$ 8,400

2. Let's find the exact amount of boxes of wrenches and hammers

Cost of the order = Price of box of wrenches * Number of boxes of wrenches  + Price of box of hammers * Number of boxes of hammers

Replacing with the real values:

8,400 = 100 * 40 + 300 * Number of boxes of hammers

8,400 = 4,000 + 300 * Number of boxes of hammers

- 300 * Number of boxes of hammers = 4,000 - 8,400

- 300 * Number of boxes of hammers = -4,400

Number of boxes of hammers = -4,400/300 = 14.67 ≈ 15

For making a order without fractions or decimals of a box, it will contain just whole numbers, this way:

15 boxes of hammers + 39 boxes of wrenches

Cost of Howard's order = 15 * 300 + 39 * 100 = 4,500 + 3,900 = 8,400

Howard ordered 18 boxes of wrenches and 22 boxes of hammers. This solution was found by solving the system of equations derived from the total number of boxes and the total cost of the order.

Let's denote:

w  as the number of boxes of wrenches Howard ordered.

h  as the number of boxes of hammers Howard ordered.

Given:

1. Each box of wrenches costs $100.

2. Each box of hammers costs $300.

3. Howard ordered a total of 40 boxes.

4. The total cost of the order is $8400.

We can set up a system of equations based on the given information:

1. The total number of boxes ordered:

w + h = 40

2. The total cost of the order:

100w + 300h = 8400

Now, let's solve this system of equations.

We can use the first equation to express one of the variables in terms of the other:

h = 40 - w

Substitute this expression for h into the second equation:

100w + 300(40 - w) = 8400

Now, let's solve for w:

100w + 12000 - 300w = 8400

-200w = 8400 - 12000

-200w = -3600

w = 3600 ÷ 200

w = 18

Now, we can find h using the first equation:

h = 40 - w

= 40 - 18

= 22

So, Howard ordered 18 boxes of wrenches and 22 boxes of hammers.

How much water should be added to 6 gallons of pure acid in order to obtain the 24% acid solution?
HELP

Answers

Answer:

19 gallons

Step-by-step explanation:

Let x gallons be the amount of water which should be added to 6 gallons of pure acid in order to obtain the 24% acid solution.

Amount of water = x gallons

Amount of pure acid = 6 gallons

Amount of acid solution = x + 6 gallons

Amount of acid in acid solution = 24%

So, there are [tex]0.24(x+6)[/tex] gallons of acid in acid solution.

Hence,

[tex]0.24(x+6)=6[/tex]

Solve this equation. Multiply it by 100:

[tex]24(x+6)=600\\ \\24x+144=600\\ \\24x=600-144\\ \\24x=456\\ \\x=19\ gallons[/tex]

A cell phone company mistakenly advertises that their data plan costs "0.02 cents" for every kilobyte of data

Answers

It could’ve been higher or lower for the cost of kilobyte of data. That is the answer because there isn’t no information or a picture of the question.

Hope this helps :)
Final answer:

The cell phone company made a error in the conversion of cents to dollars in their advertisement. They advertised the cost as 0.02 cents/kilobyte, but they probably meant $0.02/kilobyte.

Explanation:

The cell phone company is advertising their data plan costs at 0.02 cents per kilobyte but it seems like they may have meant $0.02/kilobyte which is different. Understanding the difference requires Mathematics concepts such as understanding of decimals and units conversion. If we take the advertised rate of 0.02 cents/kilobyte, it means for every 1 kilobyte of data, we will only be charged 0.0002 dollars. This is very cheap compared to charging $0.02/kilobyte. The error occurred because the company did not convert cents to dollars correctly, as $1 is equal to 100 cents, not 1 cent.
