Kimmy has 47 ft.² of cement blocks each square block has size 1 foot long what is the greatest perimeter of a rectangle that she
blagie [28]

Answer:

The larges perimeter she can make becomes is 96 ft

Step-by-step explanation:

Here we note that the available brick is 47 ft²

Therefore, she has 47 square cement blocks

Let the length of the sides of the rectangle with the most perimeter be x and y

Then 2·x + 2·y = 47 which is not possible because 47 is a prime number

Hence we have the possible sides of the rectangle is a single line of square blocks such that

x × y  = 47 ft² where y = 1 hence x = 47

The larges perimeter she can make becomes, 2 × (1 + 47) = 96 ft.

Rewrite each expression in factored form using the greatest common factor. 11. 16x+48 12. 28x+ 32y 13. 11w+hw pls help!!!
34kurt

Answer:

16(x + 3)

4(7x + 8y)

w(11 + h)

Step-by-step explanation:

16x + 48

The greatest common factor of 16 and 48 = 16

Hence, expressing 16x + 48 in factored form:

16x + 48 = 16(x + 3)

28x + 32y

Greatest common factor of 28 and 32 = 4

Hence,

28x + 32y = 4(7x + 8y)

11w + hw

11w + hw = w(11 + h)

Round 672,831 to the nearest ten thousand
Alik [6]
Well, you just have to take what I said before:

1=ones digit
3=tens digit
8=hundreds digit
2=thousands digit
7=ten thousands digit
6=ten thousands digit

So like previous answers, you just look at the digit after the one being asked

So look at the thousands place. 2,831 or 2,000 since all numbers after that digit is irrelevant

Is 2,000 or 2,831 over the halfway point to 10,000? The halfway point being 5,000

No, it is not so that means 2,831 is closer to 670,000 rather than 680,000

Answer: 672,831 rounded to the nearest ten thousand IS 670,000
