The perimeter of a rectangle is 90 feet, and the length is 32 feet. What is the width of the rectangle?
A. 26 feet
B. 13 feet
C. 58 feet
D. 15 feet

Answers

Length is 12ft, width is 4 ft.

2 x (length + width) = perimeter = 32 ft

⇒ length = 16ft - width [1]

length x width = area = 48 sq ft

Using [1] above:

⇒ (16ft - width) x width = 48 sq ft

multiplying out and rearranging:

⇒ width2 - 16 x width + 48 = 0

factorizing:

⇒ (width - 4)x(width - 12) = 0

Thus width = 4 or 12, so using [1] above:

⇒ width = 4ft, length = 16 - 4 = 12ft

or width = 12ft, length = 16 - 12 = 4ft

Convention is that the length is larger than the width, thus rectangle is 12ft long by 4 ft wide.

Answer:

15 ft

for number 5 its:

-15 -8 8/9 -3.3

and for number 6 its:

-3.3 -8 8/9 and -15

also sorry if its wrong

When it seems the negative number get bigger, they’re actually getting smaller. For example -13 is greater than -20. Plus, the absolute value would always be positive.


The answer to number 1 would be:

-15 < -8 8/9 < -3.3


The answer to number 2 would be:


15 < -3.3 < -8 8/9

Hey guys. So I'm doing a basic program for a battle game in Javascript, and I've having trouble on this one question. (subtraction)

If I have one number like 20, then 3 numbers such as 2, 4 and 7, I could easily find out which number in those 3 i subtracted by. For example if I had 18 as the answer, then I could do 20 - 18 and get 2 from the 3 numbers.

But how do I do that twice? or three or more after that one time? how would I know which one I picked after? (after the number is used once, it can still be used forever on, it's always random)

Volume = 120 cubic cm

Step-by-step explanation:

We would apply the formula for determining the volume of a square bases pyramid which is expressed as

Volume = 1/3 x base area x height

From the diagram,

length of square base = 6 cm

The base area = 6^2 = 36

height = 10

Thus,

Volume = 1/3 x 3/6 x 10

Volume = 120 cubic cm

1. Solve the compound inequality. You do not need to graph the solution.

Answers

Answer:

9 ≤ x ≤ 7

Step-by-step explanation:

2x – 3 ≤ 11 or –8x – 10 ≤ – 82

We shall determine the value of x in both case.

2x – 3 ≤ 11

Collect like terms

2x ≤ 11 + 3

2x ≤ 14

Divide both side by 2

x ≤ 14/2

x ≤ 7

–8x – 10 ≤ – 82

Collect like terms

–8x ≤ – 82 + 10

–8x ≤ – 72

Divide both side by –8

x ≤ – 72 / –8

x ≥ 9 (since we divided by a negative sign)

9 ≤ x

Combining both answers

x ≤ 7

9 ≤ x

Thus,

9 ≤ x ≤ 7

The total value of an investment was $305.33 after $240 was invested for 10 years compounded monthly. Find the interest interest rate.

Answers

Answer:

Interest rate = 2.41%

Step-by-step explanation:

The total value of an investment was $305.33 after $240 was invested for 10 years compounded monthly. Find the interest rate.

The formula to calculate the Interest rate for a Compound Interest is given as:

Solving for rate r as a decimal

r = n[(A/P)^1/nt - 1]

r = 12 × [(305.33/240.00)^1/(12)(10) - 1]

r = 0.0240996

Then convert r to R as a percentage

R = r * 100

R = 0.0240996 * 100

R = 2.41%/year

Therefore, the Interest rate = 2.41%

Kieth has landscaping bricks that are 0.75 feet long. Kieth puts 19 bricks end to end along a sidewalk. What is the total length of all thee red bricks he uses. Enter your answer in the box

Answers

Answer: 14.25 ft

Step-by-step explanation:

Assuming all the bricks used are red:

Keith puts 19 bricks end to end along a sidewalk and each one of those bricks is 0.75 ft long.

When put end to end therefore, the total length will be that length multiplied by the number of bricks laid:

Total length = Number of bricks laid * Length of each brick

= 19 * 0.75

= 14.25 ft
