If it's an isosceles triangle, the answer should be 87*42yd. In a right triangle, the area is (height*base)/2. if the height perfectly divides the triangle in half, there's no need to divide h*b by 2.

Answer:

$0.88

Step-by-step explanation:

cost per 1% = 22 ÷ 100 = 0.22

⇒ cost of 4% = 4 x 0.22 = 0.88

4% = 4/100 = 0.04

⇒ 4% of 22 = 0.04 x 22 = 0.88

Convert 500 cubic feet to liters then to gallons

V125BC [204]

Answer:

500 cubic feet equals 14158.4 liters or 3740.25 gallons.

Step-by-step explanation:

We are asked to convert 500 cubic feet to liters then to gallons.

We know that one cubic feet equals 28.3168 liters.

$\text{500 cubic feet to liters}=\text{500 cubic feet}\times \frac{\text{28.3168 liters}}{\text{cubic feet}}$

$\text{500 cubic feet to liters}=500\times \text{28.3168 liters}$

$\text{500 cubic feet to liters}=\text{14158.4 liters}$

We know one liter equals 0.264172 gallons.

$\text{14158.4 liters to gallons}=\text{14158.4 liters}\times\frac{0.264172\text{ gallons}}{\text{liter}}$

$\text{14158.4 liters to gallons}=14158.4 \times 0.264172\text{ gallons}$

$\text{14158.4 liters to gallons}=3740.2528448\text{ gallons}$

$\text{14158.4 liters to gallons}\approx 3740.25\text{ gallons}$

Therefore, 500 cubic feet equals 14158.4 liters or 3740.25 gallons.
