Answer:

1) width = 10 + 2x

length = 20 + 2x

2) area = (10 + 2x)(20 + 2x)

= 4(5 + x)(10 + x)

3) 4(5 + x)(10 + x) = 600

(5 + x)(10 + x) = 150

50 + 15x + x^2 = 150

x^2 + 15x - 100 = 0

(x - 5)(x + 20) = 0

x = 5 feet

Histogram named as ALTDCPoints Scored in One SeasonALTDC. 3 games scored between 69 to 76, 6 games scored between 77 to 84, games scored between 85 to 92 and 1 game scored between 93 to 100.

According to the histogram, in what percentage of games did the team score between 77 and 92 points?
Round your answer to the nearest percent.

Answers

umm im older and I dont even understand that

The percentage of games did the team score between 77 and 92 points is 78%.

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

We have,

Total games = 3 + 6 + 8 + 1 =18

and, number of games in which points between 77 and 92.

= 6 + 8

= 14

Now, the percentage of games did the team score between 77 and 92 points

= 14/18 x 100

= 77.777%

= 78%

The 25 members of the track team must each buy a t - shirt that costs 18.54. There are 9 members who have already bought shirts. How much money remains to be collected from the members who have NOT yet bought shirts?

Answers

Answer:

$296.64

Step-by-step explanation:

First, multiply 18.54 with 25.

18.54 x 25 = 463.5

Nine of the members have already paid for the cost. Multiply 18.54 with 9, and subtract the amount gotten from the total.

18.54 x 9 = 166.86

463.5 - 166.86 = 296.64

$296.64 still needs to be collected from the members who have not bought a shirt yet

Nine of the members have already paid for the cost. Multiply 18.54 with 9, and subtract the amount gotten from the total.

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $3800 and his stock in Company B was worth $3400. The stock in Company A has decreased 22% since last year and the stock in Company B has decreased 12%. What was the total percentage decrease in the investor's stock account? Round your answer to the nearest tenth (if necessary).

Answers

Answer: The total percentage decrease in the investor's stock account is 34%

Step-by-step explanation:

The investor's stock in Company A= $3800

The investor's stock in Company B= $3400

Percentage decline in stock of company A= 22%

Decline in value of stock of company A= 3800× 22/100

= 38×22

= $836

Percentage decline in stock of company B= 3400×12/100

= 34×12

=$408

Total decline in wealth of investor= 836+ 408

= $1244

Total percentage decline in wealth= 1244×100/7200

= 124400/7200

= 17.27%

The percentage decrease in investor's stock is 17.27%

Answers

Answer:

5.906 x 10^9

Step-by-step explanation:

(6.25 x 10^9) − (3.44 x 10^8).

step 1: make the exponents have common value

Move decimal point of 3.44 to the left once and add 1 to it's exponents.

that is 3.44 x10^8 becomes 0.344 x 10^9

= 6.25 x 10^9 - 3.44 x 10^8

= 6.25 x 10^9 - 0.344 x 10^9

step 2: bring out the common factor 10^9 since the exponents are the same.

Also, subtract the decimal numbers.

= (6.25 -0.344) 10^9

6.25 - 0.344 = 5.906

Therefore, the result is 5.906 x 10^9.

When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.

When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

The Cost C (in dollars) of making n bracelets is represented by C=45n+125. How many bracelets are made when the cost is $845?

Answers

So we know the cost is $845, which means this is the cost or our C. Lets input this into our equation and solve.

845 = 45n + 125.

Subtract from both sides:

845-125 = 45n + 125-125

720 = 45n

Divide by 45:

720 / 45 = 45n / 45

16 = n

This means that 16 bracelets can be made if the cost is 845.

We can also re-input the information into the equation to be extra sure!

845 = 45 (16) + 125.

845 = 720 + 125.

845 = 845

Yes!

A right rectangular prism has length 3 1/3 ​, width 2 1/3 ​, and height 1 1/3 . You use cubes with fractional edge length 1/3 to find the volume. How many cubes are there for each of the​ length, width, and height of the​ prism? Find the volume.

Answers

To find the number of cubes for each dimension of the prism, we need to divide the length, width, and height of the prism by the edge length of the cubes.

For the length, we have:

3 1/3 ÷ 1/3 = 10

So there are 10 cubes along the length of the prism.

For the width, we have:

2 1/3 ÷ 1/3 = 7

So there are 7 cubes along the width of the prism.

For the height, we have:

1 1/3 ÷ 1/3 = 4

So there are 4 cubes along the height of the prism.

To find the volume of the prism, we can multiply the number of cubes along each dimension.

Volume = length × width × height

Volume = 10 × 7 × 4

Volume = 280 cubic units

So the volume of the prism is 280 cubic units.
