Answer:
751.124
Step-by-step explanation:
area of a cricle is
πr^2
take π to be 22÷7
A= πr^2
A=22÷7*15*15
A=22÷7*225
7 divides 225
= 34.142
22*34.142
A= 751.124
Answer:
<em>The cost to manufacture 63 chairs, and that cost is 2268.</em>
Step-by-step explanation:
<u>Mathematical Models</u>
The cost to manufacture x chairs is given as the math model:
C(x)=36x
For example, to manufacture 10 chairs, we write:
C(10)=36*10=360
According to the explained above, the statement C(63)=2268 means we are calculating the cost to manufacture 63 chairs, and that cost is 2268.
Answer:

Step-by-step explanation:
we have

Solve for t
That means ----> Isolate the variable t
Multiply by b both sides to remove the fraction

Factor the variable t in the left side
![t[b+a]=b](https://tex.z-dn.net/?f=t%5Bb%2Ba%5D%3Db)
Divide by (b+a) both sides

Answer:
x=33
Each base angle measures 69 degrees
Step-by-step explanation:
the 2 base angles are equal so the measure of 1 base angle = (180 - 42) / 2
= 69 degrees
2x + 3 = 69
2x = 66
x = 33
