Answer:
Step-by-step explanation:
Lets find out first the Area of the rectangle building
A=50*100=5000 ft^2
we have 2 circles with the radius of 42 ft, r=21ft
Acircle=3.14*(21)^2=1384.74
Area of 2 circles=2*1384.74=2769.48
What is not covered by the rings is
5,000.00-2769.48=2230.52, rounded is 2231
Choice A
25 - 6r = 25
-6r = 25-25
-6r = 0
r = 0/-6
r = 0
They charge $30 per month as a base so that is y
They also charge $0.25 per text message, this is x
so $0.25x+$30y=$59.50
first subtract 30 from both sides to get x alone
$0.25x=$29.50
To find amount of text messages sent, we have to divide
$29.50/$.25
29.50/.25=118
This person sent 118 text messages
Each costume needs 58 yards of ribbon and since you have 24 costumes, you need to multiply both of them.
58×24=1392
