Answer:
13.04 cm^2
Step-by-step explanation:
Larger Circle diameter is 12.5 cm and the smaller is 3.5 cm
The Area of a circle is A = πr^2 = πd^2/4
Larger Circle divide the diameter by 2 = 6.25 cm
Smaller Circle dive the diameter by 2 = 1.75 cm
Using above formula A = 122.71846303085 cm^2 &
Finally we deduct the smaller Area from the larger Area
A = 9.6211275016187 cm^2 - 9.6211275016187 cm^2
122.71846303085 cm^2 - 9.6211275016187 cm^2 =
113.0973355292 cm^2 thus 13.04 is your answer since I used the
π = 3.1415926535898
A = area
π = pi = 3.1415926535898
Answer:
correct
Step-by-step explanation:
Answer:
-2755 plants
-40mg is left.
Step-by-step explanation:
Given the fertilizer amount is 1.08kg, and the amount per plant per year is (4*98mg):
#convert the weight of the fertilizer into grams then divide by quantity per plant to determine number of plants;
-There are 2755 plants planted.
-We subtract the fertilizer used from the total to find what is left:
Hence, 40 mg of the fertilizer is left over.
13 teams of 12 players each team is 12x13 that equals 156 total number of players. Hope that helps
Set Abe as x
set Bella as y
set Carlos as z
<span>Bella has earned 10 less credits than Abe
y=x-10
</span><span>Carlos has earned two less than double the number of Abe’s credits
</span><span>z=2x-2
</span><span>Altogether, they have earned a total of 136 credits
</span><span>x+y+z=136
replace y with x-10
replace z with 2x-2
x+(x-10)+(2x-2)=136
solve for x
4x-12=136
4x=148
x=37
We now know Abe earned 37 credits
To find how much Bella earned plug in 37 for y=x-10
y=27
To find how much Carlos earned plug in 37 for z=2x-2
z=72
Therefore,
Abe earned 37 credits
Bela earned 27 credits
Carlos earned 72 credits
