Small bag = 2x
Medium bag = 3x
Large bag = 7x
2x + 3x + 7x = 60
12x = 60
x = 60/12
x = 5
Small bag = 2(5) = 10 kg
Medium bag = 3(5) = 15 kg
Large bag = 7(5) = 35 kg
Done.
Answer:
Step-by-step explanation:
5/8x = 1/2x + 2
5/8x - 1/2x = 2
46x = 2
x=16
So you want to get x by itself so you. First you get 5/8x and 1/2 and subtract 1/2 from both sides. Then find the common demonantor for both numbers. After use inverse operations to multiply both sides by the reciprocal of the fraction coefficient. Finally check the solution by substituting 16 for x in the original equation.
The surface area of the right prism with an isosceles triangle base is 720 inches squared.
<h3>Surface area of a triangular prism</h3>
surface area = bh + l(x + y + z)
where
- b = base of triangle.
- h = height of triangle.
- l = height of the prism.
- x, y and z are the side of the triangle.
Therefore,
b = 24 inches
h = 5 inches
x = 13 inches
y = 13 inches
z = 24 inches
l = 12 inches
Surface area = 24 × 5 + 12(13 + 13 + 24)
Surface area = 120 + 12(50)
Surface area = 120 + 600
Surface area = 720 inches²

Then , Critical value : 
The formula to find the margin of error : -
Hence, the margin of error for the confidence interval for the population proportion with a 98% confidence level =0.065
Answer:
24 in
Step-by-step explanation:
Area of triangle = bh/2
= (2 * 24)/2
= 24 in
