Answer:
4. About 2,700 in2
Step-by-step explanation:
The area of a circle (
), measured in square inches, is directly proportional to the square of its diameter (
), measured in inches. That is:
Where 
is the constant of proportionality, dimensionless.
In consequence, the following relationship between circles A and B is obtained:
The area of the circle B is now cleared:
Given that 
, 
and 
, then:
Therefore, the correct answer is 4.
This question is missing information. Post the entire question.
If you want to solve this problem using formulas, there are two important formulas:
t1 = first term = -5
tn = nth term = last term = -5
n = numbr of terms
Sn = sum of the n terms
tn = t1 + (n - 1)d ---> 65 = -5 + (n - 1)(5)
65 = -5 + 5n - 5
65 = -10 + 5n
75 = 5n
n = 15
Sn = n(t1 + tn)/2 ---> Sn = 15(-5 + 65)/2
Sn = 450
So ur answer rounds up to 450

Answer:
a. m DCB =<DAB=120 opposite angle of the parallelogram are equal
again
BP=PD diagonal bisect it
3x+7=-x+17
3x+x=17-7
4x=10
x=10/4=5/2
b. BD =3x+7-x+17=3×5/2+7-5/2+17=2×5/2+24=5+24=29
Subtract:
189.95 - 45.00 = 144.95
the cost = 144.95
