Answer:
67%
Step-by-step explanation:
First of all, we must find the decrease;
39 - 13
=26
Then we can find the percentage decrease
26/13 ×100 =66.666..which can be written as 67.
Y+3x=2----equation1
y-2x=-3-----equation 2
e1-e2
(y+3x)-(y-2x)=2-(-3)
y+3x-y+2x=5
5x=5
x=1
sub x=1 into equation 1
y+3(1)=2
y=-1
You take 50 times .082 which is 8.2% in decimal form to get 4.1
Answer:
The answer to your question is: A = 1627.35 in²
Step-by-step explanation:
Data
height = 30 in
radius = 7 in
A = ?
Lateral area
A = 2πrh
A = 2(3.1416)(7)(30) = 1319.47 in²
Area of the base and lid
A = 2 x πr² = 2(3.1416)(7)²
= 307.88 in²
At = 1319.47 in² + 307.88 in² = 1627.35 in²
Polygons, Number of sides, Measure is angles, and angle sums
