Find thy radius.
Thy radius is 7.25 (D / 2 = R)
Thy formula for area is A = (pi)r^2
Substitute and Solve
A = (pi)r^2
= (pi)(7.25)^2
= (pi)(52.5625)
= 165.04625
Therefore, the area is about 165.
A+c=100
3a+2c=275, from the first c=100-a making the 2nd equation become:
3a+2(100-a)=275 perform indicated multiplication on left side
3a+200-2a=275 combine like terms on left side
a+200=275, subtract 200 from both sides
a=75, and since c=100-a
c=100=75=25
So the answer is D. 25 children and 75 adults
Equation 1: a+c=100
Equation 2: 3a+2c=275
A) GBL
The reason is because the angle is at P and at B. Between line segment GB and and PX are the same so the letters would be ordered as GBL
Answer:
Computer disks are $4 each
Notebooks are $3 each
Step-by-step explanation:
For the first equation
<em>$4 x 2 disks = $8</em>
<em>$3 x 3 notebooks = $9</em>
<em>$9 + $8 = </em>$17
For the second equation
<em>$4 x 5 disks = $20</em>
<em>$3 x 4 notebooks = $12</em>
<em>$20 + $12 = </em>$32
