Base = x
height = x-4
Area = .5 * height * base
48 = .5 * (x-4) * x
96 = x^2 -4x
x^2 -4x -96=0
x = 12
base = 12
height = 8
Answer:
-20/13 <g
Step-by-step explanation:
-7–5(3g+8)<10g–7+g
Distribute
-7–15g-40<10g–7+g
Combine like terms
-15g - 47 < 11g -7
Add 15 g to each side
-15g+15g -47< 11g+15g -7
-47 < 26g -7
Add 7 to each side
-47+7 < 26g-7+7
-40 < 26g
Divide each side by 26
-40/26 <26g/26
-40/26 <g
Divide top and bottom by 2
-20/13 <g
1) The larger number is 33.
2) Joan weighs 47.5 kg, and Annie weighs 44.5 kg.
3) Ronnie walks at a rate of 4 km/h, while Margie walks at a rate of 2 km/h.
4) It takes 3 hours for Lea to do the same task working alone.
5) Katie is 5 years old and Rico is 1 year old.
To solve each problem, the following calculations must be done:
1)
(54 - 12) / 2 = X
42 / 2 = X
21 = X
21 + 12 = 33
33 + 21 = 54
2)
(92 - 3) / 2 = X
89 / 2 = X
44.5 = X
44.5 + 3 = 47.5
44.5 + 47.5 = 92
3)
1000 / 3 x 2 = 666.666
0.666 x 6 = 3.999
0.333 x 6 = 1.999
4)
1/5 + 1/X = 1/2
10/5 + 10/X = 10/2
2 + X = 5
X = 5 - 2
X = 3
5)
5 /// 1
8 /// 4

Answer:
Step-by-step explanation:
The formula for volume of a cylinder is
V = πr²h where r is the radius and h is the height.
We are given r = 5 and h = 2.5, plug those values in and simplify...
V = π(5²)(2.5)
V = π(25)(2.5)
V = 62.5π
