So this is like a pie chart or fractions
20 degreees is x% or x/whole parts
circle=360degrees
20/360=2/36=1/18
so the area represents 1/18 of the circle
684=1/18 of circle
multply both sdies by 18
12312=18/18 circle
the area of the circle=12312 yd^2
<u>520 m²</u>
Here given:
length: 10 m
width: 8 m
height: 10 m
surface area of rectangular prism:
2(lw+hw+hl)
2(10*8+10*8+10*10)
2(80+80+100)
2(260)
520 m²
Answer:
The following are the answers:
a = 1
b = 6
c = -55
Step-by-step explanation:
When looking for a, b, and c in a quadratic, you are looking at coefficients only. The coefficient of x^2, which in this case is 1, is a. The coefficient of x, which in this case is 6, is b. Lastly, the constant at the end, which in this case is -55, is c.
Answer:
2.750
Step-by-step explanation:
First, have the answer as a fraction. It is in eighths.
Answer as a fraction is 6/8.

Answer: 
Step-by-step explanation:
1. You have the following expression given in the problem above:
2. Then, according to the Negative exponent rule, you have that:
3. So, based on the rule shown above, the negative exponents indicates that 
must be in the denominator and 
must be in the numerator. Therefore, you obtain the following expression:
