Answer:

The distance between A and B is l(AB) = 13 units

Step-by-step explanation:

Given:

let,

A ≡ ( x1, y1 ) ≡ ( 0, 12 )

B ≡ ( x2, y2 ) ≡ ( 5, 0 )

To Find:

Length AB = ?

Solution:

Answer:

$30,000 and $55,000

Step-by-step explanation:

If 4.5% loan is x, and the 6% loan is y, then:

x + y = 85000

0.045x + 0.06y = 4650

Solve the system of equations with substitution or elimination.  Using substitution:

0.045x + 0.06(85000 − x) = 4650

0.045x + 5100 − 0.06x = 4650

450 = 0.015x

x = 30000

y = 55000

Loan I = $ 30,000

Loan II = $ 55,000

Total loan of $ 85,000

Loan I rate at 4.5%

Loan II rate at 6%

This year's loan repayments are $ 4,650

0.045 + 0.06 = 4,650

Loan II = $ 85,000 - Loan I

0.045 ($85,000-b)+0.06 b= 4,650

Loan II = $55,000

Loan I = $ 85,000 - Loan II

Loan I = $85,000 - $55,000

Loan I = $30,000

Loan I rate = $ 1,350

Loan II rate = $ 3,300

Total Loans rate (I + II) - Payments = ($ 1,350  + $ 3,300) - $ 4,650 = $ 0 (Remaining balance)

Loans are a type of debt that can involve all types of tangible objects, although usually more often are identified with monetary loans. Like other debt instruments, a loan requires a redistribution of financial assets over time between the borrower (indebted) and the debtor (the creditor).

The borrower initially receives an amount of money from the lender to be paid back, often in the form of periodic installments, to the lender. This service is usually provided with certain costs which are referred to as interest on the debt. Borrowers can also get restrictions in the form of loan conditions.

Before applying for a loan you should know how to calculate the percent interest on a loan to check the correctness of the interest calculation specified on your credit.

The water should fill the aquarium to 1.5 feet

Solution:

Given that the directions for the aquarium say that it should be filled with 9 cubic feet of water.

This means volume of aquarium is 9 cubic feet

Given that aquarium is 2 feet wide and 3 feet long

To find: Height of aquarium

Since a aquarium is in shape of cuboid, we can use the volume of cuboid formula

The volume of cuboid is given as:

volume of cuboid = [tex]l \times w \times h[/tex]

Where "l" is the length

w is the width

"h" is the height

Substituting the values, we get,

[tex]9 = 3 \times 2 \times h\\\\9 = 6 \times h\\\\h = \frac{9}{6} = 1.5[/tex]

Thus the height of aquarium is 1.5 feet

Answer:

1/2

Step-by-step explanation:

both have equal chances

The required probabilities are 3/8 and 1/8 respectively.

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.

Given here: Jackie has 6 skirts and 2 dresses.

Total number of dresses=8

Thus the probability of picking a skirt is = 6/8

                                                                   =3/4

And the probability of picking a dress is =2/8

                                                             =1/4

Also, the probability of choosing either shoe is 1/2

Therefore the conditional probability that she chooses a skirt and brown shoes is = 3/4×1/2

              =3/8

Similarly Probability( dress+black shoes)=1/4×1/2

                                                                   =1/8

Hence, The required probabilities are 3/8 and 1/8 respectively.

Answer:

The speed of the pass that clocked is  30.31 yards per seconds

Step-by-step explanation:

Given as :

The speed of the pass = 62 miles per hour

Let The speed in yards per second = x yps

So, ∵ The speed = 62 miles per hour

Or, The speed = [tex]\dfrac{\textrm 62 miles}{\textrm 1 hour}[/tex]

or,  The speed = [tex]\dfrac{\textrm 62 miles}{\textrm 3600 secons}[/tex]

∵ In 1 hour = 3600 seconds

So, The speed = 0.0172 miles per second

Now, Again

Since 1 mile = 1760 yards

So, 62 miles = 1760 × 62 = 109,120 yards

∴ The speed in yard per second = [tex]\dfrac{\textrm 109,120 yard}{\textrm 3600 seconds}[/tex]

I.e The speed in yards per second = 30.31 yards per seconds

Hence The speed of the pass that clocked is  30.31 yards per seconds Answer

Hannah is 1 year old, and Biff is 26 years old today.

Let's denote Hannah's current age as H and Biff's current age as B.

According to the given information, we can set up two equations based on the provided conditions.

Biff is 25 years older than Hannah today:

B=H+25

Four years from now, Biff will be 6 times as old as Hannah will be:

B+4=6(H+4)

Now, we have a system of two equations with two variables.

We can substitute the expression for B from the first equation into the second equation:

(H+25)+4=6(H+4)

Combine like terms:

H+29=6H+24

Subtract H from both sides:

29=5H+24

Subtract 24 from both sides:

5H=5

Divide by 5:

H=1

So, Hannah is currently 1 year old. To find Biff's age, we can use the first equation:

B=H+25

B=1+25

B=26

Therefore, Hannah is 1 year old, and Biff is 26 years old today.

Final answer:

To calculate the total movie-going cost for five friends, multiply the cost of each item by five and sum them up. The total cost is represented by the expression [tex](5 \times\$9) + (5 \times\$3) + (5 \times\$6)[/tex], which simplifies to $90.

Explanation:

The question involves writing an expression to determine the cost for five friends to attend a movie considering the cost of tickets, drinks, and popcorn. To calculate the total cost for the group, we need to know the price per individual item and the quantity consumed. We know that each ticket costs $9, each drink costs $3, and each popcorn costs $6. Since there are five friends, we will multiply each of these costs by five to get the total cost per item for the group.

The expression for the total cost for the movie tickets is [tex]5\ tickets \ \times \$9/ticket[/tex], for drinks it's [tex]5\ drinks\ \times\$3/drink[/tex], and for popcorn, it's [tex]5\ popcorns \times\$6/popcorn[/tex]. To find the overall total, we add these expressions together:

Total Cost = [tex](5 \times\$9) + (5 \times\$3) + (5 \times\$6)[/tex]

The expression simplifies to:

Total Cost = ($45) + ($15) + ($30)

Therefore, the simplified expression for the total cost is:

Total Cost = $90

Answer:

The correct answer is A. 45.2

Step-by-step explanation:

1. Let's review all the information provided for solving this question:

Number of trees of the sample = 31

Number of trees of the sample with a height between 60 and 65 feet tall height = 3

Number of trees of the sample with a height between 65 and 70 feet tall height = 3

Number of trees of the sample with a height between 70 and 75 feet tall height = 8

Number of trees of the sample with a height between 75 and 80 feet tall height = 10

Number of trees of the sample with a height between 80 and 85 feet tall height = 5

Number of trees of the sample with a height between 85 and 90 feet tall height = 2

2. Let's calculate the percentage of the trees that are less than 75 feet tall:

Percentage of the trees less than 75 feet tall = [(Number of trees of the sample with a height between 60 and 65 feet tall + Number of trees of the sample with a height between 65 and 70 feet tall + Number of trees of the sample with a height between 70 and 75 feet tall)/Number of the trees of the sample] * 100

Replacing with the real values, we have:

Percentage of the trees less than 75 feet tall = [(3 + 3 + 8)/31] * 100

Percentage of the trees less than 75 feet tall = [(14)/31] * 100

Percentage of the trees less than 75 feet tall = 0.451613 * 100

Percentage of the trees less than 75 feet tall = 45.1613% = 45.2% (Rounding to one decimal place)

The correct shape for the cross-section of a cone, when cut perpendicularly to its axis, is a circle. This is known as a conic section. The correct option is C.

Explanation:

The student asked which shape represents the cross-section for a cone. The cross-sectional shape of a cone depends on the angle at which it is cut. If a cone is cut by a plane perpendicular to its axis (the center line from the tip to the base), the cross-section is a circle. Therefore, the correct shape for the cross-section of a cone, when cut perpendicularly to its axis, is a circle.

Step-by-step explanation:

Given

[tex]-10x+12i=20+3yi[/tex]

Two complex numbers are equal when they have equal real and imaginary parts.

Equate real parts:

[tex]-10x=20\\ \\x=-\dfrac{20}{10}=-2[/tex]

Equate imaginary parts:

[tex]12=3y\\ \\y=\dfrac{12}{3}=4[/tex]

Final answer:

The values of x and y that satisfy the given complex equation are x = -2 and y = 4, found by equating the real and imaginary parts respectively.

Explanation:

To find the values of x and y that satisfy the equation -10x + 12i = 20 + 3yi, we need to equate the real parts and the imaginary parts of the complex numbers on both sides of the equation.

For the real parts, we have:
-10x = 20
=> x = -2

For the imaginary parts, we have:
12 = 3y
=> y = 4

So the solution for the equation is x = -2 and y = 4.

We are testing the claim that males speak fewer words than females. With a p-value of 0.369, which is greater than the significance level of 0.05, we fail to reject the null hypothesis. Therefore, no significant evidence supports the claim that males speak fewer words than females.

The objective here is to test the claim that on average, males speak fewer words in a day than females. To do this, we compare two means using a hypothesis test for paired data.

The null hypothesis (H0) is that there is no difference between the mean number of words spoken by males and females. The alternative hypothesis (Ha) is that the mean number of words spoken by males is less than that spoken by females.

Since the p-value (0.369) is greater than the significance level of 0.05, we fail to reject the null hypothesis. This means we do not have significant evidence to support the claim that males speak fewer words than females.

A key takeaway from this is that the test statistic and p-value are critical elements in hypothesis testing. They determine whether or not you have significant evidence to reject the null hypothesis.

The correct expression is '2(n + 9),' which corresponds to choice D and represents two times the sum of a number and 9.

Explanation:

The expression that represents the statement 'two times the sum of a number and 9' is D. 2(n + 9). This is because you first need to find the sum of the number (let's call it n) and 9, which is represented as (n + 9). Then, the statement says 'two times' which means you need to multiply that sum by 2, resulting in 2 × (n + 9).

Answer:

Let x = (the height of the fourth plant)

Then the average of the four heights will be:

(70+71+72+x)/4

Simplify it to (213+x)/4

This average has to be at least 73 inches. Meaning, it has to be greater than or equal to 73.

(I don't have the sign for greater/equal so I'll type >=)

(213+x)/4 >= 73

This is the inequality. Just solve for x, and you have the answer.

(213+x) >= 292

x >= 79

Another way: (I think it's easier to do it like this in my head)

You need average 73.

Look at the heights of the plants you have now: how far are they from 73?

The first is 3 less, the second is 2 less, and the third is 1 less.

The 'total deficit'' is 6.

So to make the average be 73, you need to cancel out the deficit by making an equal overage (by 6).

If you can only add one more plant... that plant has to be 6 inches higher than the average you want. So 73+6=79.
