Answer:
5.5
Step-by-step explanation:
B is the midpoint of AC, D is the midpoint of CE
This means that CE = 1/2 AE
CD = 1/2 ( 11)
CD = 5.5
The correct answer is C. 5/8
The correct question is
Find the volume of a <span>cylinder with base area 25 pi cm squared and height 3 cm more than the radius
we know that
</span>[the volume of a cylinder]=[area of the base]*[height]
[area of the base]=25pi cm²
[area of the base]=pi*r²--------> r²=[area of the base]/pi----> r²=25pi/pi
r²=25--------> r=5 cm
the height is 3 cm more than the radius
so
height=3+5-----> height=8 cm
[the volume of a cylinder]=[25pi]*[8]------> 200pi cm³
the answer is
200pi cm³
For problems like this we can use algebra to help us, the farenheight 6 hours ago was:
(2xt)-6=-20
We have to balance the sides out, first we minus 6
2xt=-26
Now we can divide by 2
t=-13
We now know the temperature 6 hours ago was -13
Answer:
25 grams
Step-by-step explanation:
Pennies made after 1984 weigh 2.5 grams. How much would 10 pennies weigh?
From the above question:
1 penny = 2.5 grams
10 pennies = x grams
Cross Multiply
1 × x grams = 10 pennies × 2.5 grams
x grams = 25 grams.
Hence, the weight of 10 pennies is 25 grams
