The length of a rectangle is 9 mm and its width is 6 mm.

1 answer:

6 0

When you multiply a value by 2/3, you are finding 2/3 of that number, so your new length would be 6 and your new width would be 4. The original area was 9 × 6 = 54, and the new area is 6 × 4 = 24. 54 ÷ 24 = 2.25, or 2 1/4, so your answer is 2 1/4, which as an improper fraction is 9/4. I hope this helps!

PLS HELP ME I WILL MARK THE BRAINLIEST

Serga [27]

Answer:

1. 155 yd², 2. 379.54 ft², 5. x = 65.82π

Step-by-step explanation:

1. A = (1/2) · (3 + 13) · 8

A = (1/2)(16)(8)
A = 64
A = bh
A = 13*7
A = 91
64 + 91 = 155
155 yd²

2. A = bh
A = 25x25
A = 625
A = πr²
A = 3.14*12.5²
A = 3.14*156.25
A = 490.625
490.925/2 = 245.4625
625 - 245.4625 = 379.5375
379.54 ft²

3. and 4. Sorry, I don't know how to solve these

5. A = πr²
A = 3.14*7²
A = 3.14*49
A = 153.86
x/154 = 153.86π/360
360x = 154*153.86π
360x = 23694.44π
x = 65.8178889π
x = 65.82π

Hope this helps :)

A 14- inch pepperoni pizza is sliced into 8 equal pieces. One slice contained 352 calories. Write and solve a division equation

tankabanditka [31]

Division equation is:

$\frac{c}{8} = 352$

There are 2816 calories in whole pizza

Solution:

Given that,

A 14- inch pepperoni pizza is sliced into 8 equal pieces

One slice contained 352 calories

Therefore,

1 slice = 352 calories

Let "c" be the calories

Given that there are 8 equal pieces

Therefore, calories in 8 pieces are:

Calories in 8 pieces = 8 x calories in 1 piece

$c = 8 \times 352$

Thus the division equation is:

$\frac{c}{8} = 352$

Therefore,

$c = 352 \times 8 = 2816$

Thus there are 2816 calories in whole pizza
