Answer:

<h2>S.A. = 40 1/3 in²</h2>

Step-by-step explanation:

If the dimensions of the solid are multiplied by x, then the new one

surface area will change x² times

volume will change x³ times.

We have S.A. = 1,089 in².

The dimensions are multipled by 1/3. Therefore the Surface Area will change

(1/3)³ = 1/27 times.

1,089 in² × 1/27 = 40.333... in² = 40 1/3 in²

Cries In didn’t pay attention in class in my lower grades

Answer:

a. 32

b. 48

Step-by-step explanation:

Forty percent of the 80 birds were robins.

a. How many of the birds were robins?

b. How many of the birds were not robins?
___________________
Forty percent of the 80 birds that were robins = 40%/100%

To find how many of the birds were robins, use part/whole = part/whole

40%/100% = ?/80

This will tell us how many exact robins were there

To solve, multiply 80 by 40 and then divide all by 100

80 x 40 ÷ 100 = 32

so 32 of the birds were robins

now for b since 32 of the birds were robins out of 80 birds, subtract 32 from 80.

80 - 32 = 48

∠1 ​ and ∠2 are supplementary.
ad-work [718]
Supplementary means the 2 angles add up to 180 so...

124+(2x+4)=180

124+2x+4=180

124+2x+4-4=180-4

124+2x=176

124-124+2x=176-124

2x=52

2x/2=52/2

x=26
plug in and check

124+2x+4=180

124+2 (26)+4=180

124+52+4=180

176+4=180

180=180
