Answer:
the answer is d.
Step-by-step explanation:
first, you want to use the formula,
new value - original value
<u>____________________</u>
original value * 100
you see that 84 is the new value and 79 would be the original value. substitute the numbers in. this is a increase since you will get a positive value.
84 - 79
<u>______</u>
79 * 100
now we solve it.
5
<u>__</u>
79 * 100
you can either solve the fraction first then multiply that by 100 or multiply the numerator by 100 first then divide that by 79, each way works.
500
<u>____</u>
79 = approximately 6.3% increase (this is not a exact value, just rounded)
or
5
<u>__</u>
79 = approximately 0.063 (this is not a exact value, just rounded)
0.063 * 100 = 6.3% increase
Answer:
196 
Step-by-step explanation:
Surface are of 2 rectangles = 2(2*4) = 16 
surface are of the base rectangle = 4*3 = 12 
Area of tow triangles =2(
* 2* 2)= 4
total = 16+12+4
= 196 
Answer:
The correct answer is A.
Step-by-step explanation:
1/5*-10/1=-10/5= -2
2/3*3/1=6/3= 2

0.
Use the 30-60-90 triangle.
Tan is opposite over adjacent.

Square roots cannot be on the bottom.

The bottom cancel out the square root bar.
Your answer is:

(It's best to memorize the 30-60-90 and the 45-45-90 triangles during trigonometry. It helps a lot.)
Hope this helps!

V=pi•r^2•h. So, 3.14•16•10=502.4
