Answer:
x = 43/2 = 21.5
Step-by-step explanation:
2x - 12 + 4x + 12 + 2x + 8 = 180 (Combine Like terms)
8x + 8 = 180
43/2 = 21.5
2x = 36
Jenny’s savings multiplied by (product) 2 is 36
X will be equal to 18
A zero is in the hundredths place so we do not need to change the number in the tenths place. The answer is 32.6 If the hundredths place had a 6,7,8, or 9 than you would round to the nearest tenths place, so if you had 32.68 than you would round it to 32.7
The cost to make this steel cone is $2,543.40.
Step-by-step explanation:
Step 1:
The volume of a cone is determined by multiplying with π, the square of the radius (r²) and height (h). Here we substitute π as 3.14.
The radius of the cone is 9 cm and the height is 10 cm.
The volume of the cone,
So the volume of the cone is 847.8 cubic cm.
Step 2:
If 1 cubic cm costs $3.00, the cost of the given cone is the volume multiplied by the unit cost.
The cost to make the steel cone
The cost to make this steel cone is $2,543.40.
