$451.50

Step-by-step explanation:

FIRST FIND OUT THE TOTAL SQUARE YARDS. THERE ARE 3 FEET IN ONE YARD, SO 15/3=5. THE ROOM IN 4.3X5 YARDS 0R 21.5 SQUARE YARDS. THEN MULTIPLY THE SQUARE YARDS BY PRICE PER YARD: 21.5 X 21 = 451.5

A cube has a volume of 8 000 000 cm³.
Rus_ich [418]

The length of it's side and surface area is 2 meters and 24 meters square respectively

<h3>How to determine the parameters</h3>

The formula for calculating the volume of a cube is given as;

Volume = a^3

Where a is the length of it's side

Now, let's substitute the volume into the formula, we have

8000000 = a^3

Let's find the cube root of both sides

cube root of 8000000 = 200

cube root of a^3 = a

Then, we have

a = 200cm

The length of it's side in meters

= 200/100

= 2 meters

Surface area = 6a^2

Surface area = 6 × 2^2

Surface area = 6 × 4

Surface area = 24m ^2

Thus, the length of it's side and surface area is 2 meters and 24 meters square respectively.

A school is painting its logo in the shape of a triangle in the middle of its sports field. The school wants the height of the t
Radda [10]

Answer:

b\geq 9

In other words, the base must be at least 9 feet long.

Step-by-step explanation:

The schools wants the height of the triangle to be eight feet, and the area of the logo to be at least 36 square feet.

Recall that the area of a triangle is given by:

\displaystyle A = \frac{1}{2}bh

Since we want to area to be at least 36 square feet:

\displaystyle \frac{1}{2}bh \geq 36

We are given that the height is eight feet. Substitute:

\displaystyle \frac{1}{2}(8)b\geq 36

Simplify:

4b\geq 36

Divide both sides by four. Hence, our inequality is:

b\geq 9

In words, this means that the base must be at least 9 feet long.
