Answer:

-3.69

Step-by-step explanation:

Exponential equations can be solved by taking Ln (natural logarithm) of both sides. The rule we need to know is:

[tex]Ln(a^b)=bLn(a)[/tex]

Now lets work out this problem:

[tex]16^{2x+3}=13^{x-1}\\Ln(16^{2x+3})=Ln(13^{x-1})\\(2x+3)Ln(16)=(x-1)Ln(13)[/tex]

Using calculator, we take the values of Ln 16 and Ln 13 as:

Ln 16 = 2.7726

Ln 13 = 2.5649

Now, we can solve for x:

[tex](2x+3)Ln(16)=(x-1)Ln(13)\\(2x+3)2.7726=(x-1)2.5649\\5.5452x+8.3178=2.5649x-2.5649\\2.9803x=-10.8827\\x=-3.69[/tex]

x is -3.69 (rounded to 2 decimal places)

Answer:

The 8th term in the sequence is -128

Step-by-step explanation:

The given series is a geometric progression (G.P) with the starting term as -1.

Let the starting term be a and the common ratio be r.

a = -1

r = 2

The formula for the nth term of a geometric progression (G.P) :

[tex]nth\:term=ar^{n-1}[/tex]

n = 8

[tex]The\:8th\:term=ar^{7}=(-1)\times2^{7}=-128[/tex]

Therefore, the 8th term in the sequence is -128

Answer:

$0.89/1        the cost is $0.89.

Step-by-step explanation:

cost over lb

13.35/15

unit rate means for 1 so divide 15 by 15 to get  1  

what ever u do to the denominator do to the numerator so divide 13.35 by 15

13.35/15 divided by 15/15= 0.89/1

$0.89 for 1 lb

The unit rate is $0.89 per pound when 15 pounds cost $13.35. The cost for any other quantity can be found by multiplying the unit rate by the desired number of pounds.

To find the unit rate, which is the cost per pound in this case, you would divide the total cost by the number of pounds. The question states that 15 pounds of an item cost $13.35. Therefore, the unit rate is calculated as $13.35 divided by 15 lb, which equals $0.89 per pound.

The cost is already given as $13.35 for the 15-pound quantity. If you need to find the cost for a different quantity, you can multiply the unit rate by that quantity. For example, if you need to know the cost of 1 pound, it would be $0.89, while the cost for 5 pounds would be 5 multiplied by $0.89, which equals $4.45.

Answer: 1/3

Step-by-step explanation: Probability is the likelihood that an event will happen.

In this problem, we want to find the probability of rolling an odd number on a standard 6-sided die.

To find the probability of rolling an odd number on a 6-sided die, we first have to think about what numbers are on a standard die.

On a standard die, we have 3 odd numbers 1, 3, and 5 and 3 even numbers 2, 4, and 6.

Since there are an equal amount of even numbers and odd numbers on a standard die, we say the probability of rolling an odd number is 3 out of 6 or 3/6 since there are 3 odd numbers and 6 total outcomes we could get. The 6 total outcomes would be all the numbers on the die.

However, we have no 3/6 on the list so we can reduce this fraction by dividing the numerator and the denominator by 3 to get the equivalent fraction 1/3. Remember, always reduce when possible when finding probability.

Therefore, the probability of rolling an odd number on a standard 6-sided die is 1/3.

Answer:

3,833 for $28

2167 for $40

Step-by-step explanation:

Let X be the number of tickets sold at the price of $24, And Y be the number of tickets sold at the price of $40.

Now,   $ 28X will be the revenue generated due to the $28 tickets

And,   $40Y will be the revenue generated due to the 40$ tickets.

Now, Total revenue generated should be $194400.

Thus ,   28X + 40Y  = 194400  -(1).

Also,

Total number of seats in theater is 6000.

So, X + Y = 6000.  -(2)

X = 6000 - Y.

Put in equation 1

We get ,    168,000 - 28Y + 40Y = 194,400

                   12Y = 26,000

                      Y = 2,166.66

Since , Y is of 40 $ so minimum tickets sold should be 2167.

X = 3,833.

Final answer:

To generate a total revenue of $194,400 in a 6000-seat theater with tickets at $28 and $40, 3800 tickets should be sold at $28 and 2200 tickets should be sold at $40. This was solved using a system of linear equations.

Explanation:

To solve how many tickets should be sold at each price for a sellout show to generate a total revenue of $194,400 in a 6000-seat theater with ticket prices at $28 and $40, we can set up a system of linear equations. Let's denote the number of $28 tickets as x and the number of $40 tickets as y.

The first equation comes from the total number of seats:

x + y = 6000

The second equation comes from the total revenue:

28x + 40y = 194400

To solve the system, we can multiply the first equation by 28 to eliminate the x variable:

28x + 28y = 168000

Subtract this from the second revenue equation:

(28x + 40y)-(28x + 28y) = 194400-168000

12y = 26400

Dividing both sides by 12 gives us:

y = 2200

We can then substitute y back into the first equation:

x + 2200 = 6000

Solving for x gives us:

x = 3800

Thus, 3800 tickets should be sold at $28 and 2200 tickets should be sold at $40 for a sellout show to generate a total revenue of $194,400.

Answer:

5x-y +5 =0

Step-by-step explanation:

y – 5x = 5

5x-y +5 =0

The standard form of y - 5x = 5 is 5x – y = -5

Given equation is y - 5x = 5

We have to express in standard form

The standard form of a line is in the form Ax + By = C where A is a positive integer, and B, and C are integers.

The standard form of a line is just another way of writing the equation of a line.

So, to write the given equation in standard form we need to rearrange the terms.

Hence the equation becomes:

y - 5x = 5

On rearranging the terms, we get

-5x + y = 5

We need the x-term to be positive, so multiply the equation by -1 to get our answer

5x - y = -5

Hence the standard form is found out

Answer:

x = 40°

Step-by-step explanation:

Given that ∠SRT ≅ ∠STR

Then ∠STR = 20

∠STR  and ∠STU are what you call supplementary angles. This means that the sum of their measurements is equal to 180° because they form a straight line.

So if:

∠STR + ∠STU = 180°

m∠STU = 4x

m∠STR = 20

Then:

4x + 20° = 180°

Now we solve for x:

[tex]4x + 20 = 180\\\\Subtract\;20\;from\;both\;sides\;of\;the\;equation\\\\4x + 20 - 20 = 180 - 20\\4x = 160\\\\Divide\;both\;sides\;of\;the\;equation\;by\;4\\\\\dfrac{4x}{4}=\dfrac{160}{4}\\\\x = 40[/tex]

x = 40°

Part A: The number sentence is -3 + 12 - 2. Part B: The addition equation is 9 = -3 + 12 - 2.

Part A: To find the total yardage gained or lost by the running back, we need to add together each of the individual yardage changes. The running back first lost 3 yards, then gained 12 yards, and finally was pushed back 2 yards. The number sentence that represents this sequence of events is:

-3 (loss of 3 yards) + 12 (gain of 12 yards) - 2 (loss of 2 yards).

Part B: To rewrite this as an addition equation, we need to make sure that the total change in yardage is on one side of the equation, and the individual changes are on the other side, all connected by addition. We can do this by adding the losses as negative numbers to the gains. The total yardage gained or lost is the sum of these individual changes:

-3 + 12 + (-2).

Now, we calculate the sum:

-3 + 12 = 9,

9 + (-2) = 7.

So, the addition equation that represents the total yardage is:

7 = -3 + 12 - 2.

Final answer:

To meet the minimum sales requirement of $4800, with 18 chairs already sold, the online furniture store must sell a minimum of 6 tables.

Explanation:

The online furniture store sells chairs for $150 each and tables for $350 each. With the sale of 18 chairs, the store has already made $2700 ($150 × 18). To meet the minimum sales requirement of $4800, we must determine how many tables need to be sold.

First, subtract the total sales from chairs from the minimum sales requirement:
$4800 - $2700 = $2100.

This is the amount that must be made from the sale of tables. Since each table is sold for $350, divide $2100 by $350 to find the number of tables needed:
$2100 / $350 = 6 tables.

Therefore, the store must sell a minimum of 6 tables to meet the $4800 sales requirement, assuming 18 chairs are sold and they don't exceed the shipping limit of 20 pieces of furniture.

To meet the daily sales requirement of $4800, the store needs to sell at least 6 tables along with 18 chairs. However, given the shipping capacity of 20 pieces per day, it is not possible to meet both requirements simultaneously.

Determining the Minimum Number of Tables

We need to determine the minimum number of tables the store must sell. Given that each chair is sold for $150, the revenue from selling 18 chairs is:

Revenue from chairs = 18 chairs * $150/chair = $2700

To meet the daily sales target of $4800, the remaining required revenue from tables is:

Required revenue from tables = $4800 - $2700 = $2100

Since each table sells for $350, the minimum number of tables required can be calculated as:

Number of tables = $2100 / $350 per table = 6 tables

Therefore, to meet the daily sales requirement of $4800, the store must sell at least 6 tables.

Additionally, the store can ship a maximum of 20 pieces of furniture per day. Having sold 18 chairs, the store can ship:

Remaining pieces = 20 - 18 = 2 pieces

Since we need at least 6 tables to meet the revenue requirement, and the shipping capacity allows only 2 more pieces, **it is not possible** to meet both constraints simultaneously.

Answer:

5/9 of a foot

Step-by-step explanation:

given:

first length = 8/9 feet

second length = 1/3 feet

difference in length,

= 8/9 - 1/3

= 8/9 - 3/9

= (8-3) / 9

= 5/9 of a foot

Final answer:

The first piece of lumber is 5/9 of a foot longer than the second piece, after converting both lengths to a common denominator and performing the subtraction.

Explanation:

The question asks how much longer the first piece of lumber is than the second piece, given that one piece is 8/9 of a foot long and the other is 1/3 of a foot long. To find the difference in length between the two pieces, we subtract the length of the shorter piece from the length of the longer piece:

8/9 foot - 1/3 foot

To subtract these fractions, we need a common denominator, which is 9 in this case. Rewriting 1/3 with a denominator of 9 gives us:

8/9 - 3/9 = 5/9 foot

Therefore, the first piece of lumber is 5/9 of a foot longer than the second piece. This is a mathematics question typically suited for middle school students, who are learning about fractions and how to compute with them.

Using the area of a triangle formula, and given the area as 36 square centimeters and the height as 18 centimeters, it was calculated that the base of the triangle is 4 centimeters.

To find the base of a triangle when the area and height are known, we use the formula for the area of a triangle, which is Area = 1/2 × base × height. Given that the area is 36 square centimeters and the height is 18 centimeters, we can set up the equation as follows:

36 = 1/2 × base × 18

By rearranging the equation to solve for the base, we get:

base = (36 × 2) / 18

base = 72 / 18

base = 4 centimeters

Therefore, the base of the triangle is 4 centimeters.

Let be "x" the amount of cups of mayonnaise that he will need to make 1 cup of tuna fish salad and "y" the amount of cups of mayonnaise that he will need to make 9 times the recipe.

Knowing that it takes [tex]\frac{1}{4}\ cups[/tex] of mayonnaise to make [tex]\frac{3}{4}\ cups[/tex] of tuna fish salad, we can set up the following proportion:

[tex]\frac{\frac{1}{4}}{\frac{3}{4}}=\frac{x}{1}[/tex]

Solving for "x", you get:

[tex]\frac{\frac{1}{4}}{\frac{3}{4}}=\frac{x}{1}\\\\\frac{1}{3}=\frac{x}{1}\\\\x=\frac{1}{3}[/tex]

So "y" will be:

[tex]y=9x[/tex]

Substituting the value of "x" into the equation, we get:

[tex]y=9(\frac{1}{3})\\\\y=3[/tex]

Final answer:

Cory will need 3 cups of mayonnaise to make 9 times the recipe for 1 cup of tuna fish salad.

Therefore, the correct answer is 3 cups of mayonnaise (Option A).

Explanation:

To find out how much mayonnaise Cory will need to make 9 times the recipe for 1 cup of tuna fish salad, we need to calculate the proportional amount of mayonnaise.

It takes 1/4 cups of mayonnaise to make 3/4 cups of tuna fish salad.

So, the ratio is 1/4 : 3/4.

To find the amount of mayonnaise needed for 1 cup of tuna fish salad, we scale the ratio by multiplying both sides by 4/3: 1/4 * 4/3 = 1/3 cup of mayonnaise.

Therefore, for 9 times the recipe, Cory will need 9 * 1/3 = 3 cups of mayonnaise.
