Answer:  12,150 m²

<u>Step-by-step explanation:</u>

The ratio is 3:2 which means

Length (L) = 3x

Width (w) = 2x

Perimeter (P) = 2L + 2w

              450 = 2(3x) + 2(2x)

              450 = 6x + 4x

              450 = 10x

                45 = x

                                      L = 3x                w = 2x

                                         = 3(45)               = 2(45)

                                         = 135                  = 90

Area (A) = L × w

              = 135 × 90

              = 12,150

A square pyramid with a height of 7 inches has volume of 47.25 cubic inches. Find the side length of the square base
mixas84 [53]
Hello,
Volume of the square pyramid=
1/3×B×h where B represent Base and h represent height

Now, substitute the information that we had from this problem into the formula.
47.25=1/3×B×7
Times 3 from both side
141.75=7B
Divide B from both side
B=20.25 square inches
B=s^2
Square root it to get
s=4.5 inches. As a result, the side length of square base is 4.5 inches. Hope it help!

solve for each variable i don’t need work shown just the answers please thank you very much i have 2 hours to get this done

Answer:

(a)

x = 18.5

y = 22.5

(b)

x = 10

Step-by-step explanation:

Solving (a):

7x - 19 and 3x + 14 are interior angles.

So:

7x - 19 + 3x +14 = 180

Collect like terms

7x + 3x = 180 - 14 + 19

10x = 185

x = 18.5

7x - 19 and 5y - 2 are equal angles --- corresponding angles

So:

5y - 2 = 7x - 19

Make 5y the subject

5y  = 7x - 19+2

5y  = 7x -17

Make y the subject

y = \frac{1}{5} (7x - 17)

Substitute x = 18.5

y = \frac{1}{5} (7*18.5 - 17)

y = \frac{1}{5} (112.5)

y = 22.5

Solving (b):

The triangle is right-angled.

So:

5x + 3 + 2x + 17 + 90 = 180

Collect Like Terms

5x + 2x = 180 - 90 - 17-3

7x = 70

x = 10
