The answer is 320 to find the product you can just do 4 times 8 and then add a zero
Answer:
514.5 ft.³
Step-by-step explanation:
Volume of a triangular prism
= base area × height
In the figure, the base is a right-angled triangle.
The base area
= (7×7)÷2
= 24.5 ft²
The volume of the prism
= 24.5×21
= <u>514.5 ft³</u>
If you want to find the decimal value of a square root, you can use the 2 closest perfect squares to them.
Example
Approximate the value of sqrt20
Pick the 2 closest perfect squares, one before and one after 20:
16 and 25.
So, the square root of 20 has to be between 4 and 5.
Since 20 is closer to 16 than it is to 25,
We can estimate the decimal value of sqrt20 to be around 4.4
Answer:
-60°
Step-by-step explanation:
Your calculator and/or your knowledge of trig function values can find this for you.
The arcsine function has a range of -90° to +90°. Positive angles 240° and 300° will also have the sine value -√3/2.
arcsin(-√3/2) = -60° = -π/3 radians
Her loan would have grown by 199439.88 (If you are looking for the actual value of the ENTIRE loan. It would be 219439.88) I hope this helped ^^
