Can someone please answer and EXPLAIN ILL MARK BRAINLIEST
12345 [234]

Answer:

adjust city gallons to 3 gallons and freeway to 7 gallons

make your line in the chart:

3   |  10-3 = 7   |   3(25) = 75   |   7(40) = 280   |   75 =280 =355   |   355   |   yes

Step-by-step explanation:

x = city gallons

y = freeway gallons

x+y = 10        then y = 10-x

25x+40y = 355

substitute for y

25x+40(10-x) = 355

25x+400-40x = 355

-15x+400 = 355

subtract 400 from each side

-15x = -45

divide both sides by -15

-15x/-15 = -45/-15

x = 3 gallons

y = 7 gallons

Polygon X is similar to polygon Y. Polygon X is three times the size of polygon Y. The perimeter of polygon X is 81. What is the
maksim [4K]

Answer:  Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Polygon X is similar to polygon.

And Polygon X is three times the size of polygon Y.

So, it becomes,

\dfrac{\text{Perimeter of polygon X}}{\text{Perimeter of polygon Y}}=\dfrac{3}{1}\\\\\dfrac{81}{x}=\dfrac{3}{1}\\\\x=\dfrac{81}{3}\\\\x=27

Hence, perimeter of polygon Y is 27.

Therefore, Option 'C' is correct.

24.5 is 33 1/3% of what number?
julia-pushkina [17]

Answer: 73.5

Step-by-step explanation:

The percent <em>33 1/3% </em>represents 1/3 of 100%. We can multiply 33 1/3% by 3 and get 100%. We need to find what 24.5 is 33 1/3% of.

Since 1/3 x 3 = 100%, then 24.5 x 3 must equal the number we're trying to find.

24.5 x 3 = 73.5.

Therefore, 24.5 is 33 1/3% of 73.5. I hope this helps, and good luck!

olchik [2.2K]

Answer:

A = 12.56 m²

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS

<u>Geometry</u>

  • Area of a Circle: A = πr²
  • d = 2r

Step-by-step explanation:

<u>Step 1: Define</u>

d = 4 m

<u>Step 2: Find </u><em><u>r</u></em>

  1. Substitute:               4 = 2r
  2. Isolate <em>r</em>:                   2 = r
  3. Rewrite:                    r = 2 m

<u>Step 3: Find Area</u>

  1. Substitute:               A = π(2)²
  2. Substitute:               A = (3.14)(2)²
  3. Evaluate:                  A = (3.14)(4)
  4. Multiply:                   A = 12.56 m²
