the lenghty of a rectangal is 8 feet more than its width. the pirimete of the rectangle is 72 feet. Find the width

Answers

Answer 1
Answer:

Width of the rectangle is 14 ft

Step-by-step explanation:

  • Step 1: Let the width of the rectangle be x. Then length = 8 + x. Perimeter = 72 ft.

Perimeter = 2(length + width)

72 = 2 (8 + x + x)

72 = 16 + 4x

4x = 56

x = 56/4 = 14

∴ Width of the rectangle is 14 ft

Bill says he can add 23 and 40 without regrouping. Is bill correct? How do you know?

Answers

Answer:

Step-by-step explanation:

Yes bill is correct because both numbers are easy to add without regrouping, since when each of the digit are added there won't be carried over. Also, I believe Bill should be able to do simple mathematics like 2+3, 3+5 and so on.

Then, he should be able to add 3 plus 0 in his head and keep the result as 3. And then add the other 2+4 and he will put the two result together as 63

Yes Bill is correct because
3+0 you don't have to regroup
And 4+2 you don't have to regroup
hope this helps

Calculate the sum of the infinite series

Answers

Answer:

S_\infty=250.

Step-by-step explanation:

The given infinite series is  50+40+32+(128)/(5)+....


The first term of this series is a_1=50.


The common ratio is r=(40)/(50).

\Rightarrow r=(4)/(5).


The sum of this infinite series is given by the formula,


S_\infty=(a_1)/(1-r)


We now substitute all the above values in to this formula obtain,


S_\infty=(50)/(1-(4)/(5))


This implies that,

S_\infty=(50)/((1)/(5))


This simplifies to,


S_\infty=50* 5


S_\infty=250.


The correct answer is C.

4^2 + 5 • 3^2 – 4^2 ÷ 2^3

Answers

Following the order of operations:
4^2 + 5 * 3^2 – 4^2 / 2^3
16 + 5 * 3^2 – 4^2 / 2^3
16 + 5 * 9 – 4^2 / 2^3
16 + 5 * 9 – 16 / 2^3
16 + 5 * 9 – 16 / 8
16 + 45 – 16 / 8
16 + 45 – 2
61 – 2
