The math club has 12 members. Each member pays monthly dues of $13.20. On the first day of the month, 8 members paid their dues. The remaining members paid their dues on the second day of the month. How much money was collected in dues on the second day of the month?

Answers

Answer: $52.80

Step-by-step explanation:

Number of members = 12

Monthly due per member = $13.20

Total amount expected = $13.20 × 12 = $158.40

On the first day of the month, 8 members paid their dues. Total amount paid will be:

= 8 × $13.20

= $105.60

The money that was collected in dues on the second day of the month will be:

= $158.40 - $105.60

= $52.80

What is the radius of a hemisphere with a volume of 10470 in?, to the nearest tenth
of an inch?

Answers

Answer:

r ≈ 17.1 in

Step-by-step explanation:

Volume Of Hemisphere: 10,470

Volume Of Sphere: 20,940

Volume Of A Sphere: V = 4/3π(r)^3

20,940 = (4.1887902)r^3  [Evaluate 4/3π In Calc]

20940                  =                    (4.1887902)r^3

4.1887902                                     4.1887902

4999.0567625 = r^3

∛4999.0567625 = ∛r^3

17.0986841 = r

r≈17.1 in

Answers

x=6. explanation: first you would start off by using the distributive property which would be: 2(x-3)+4=10 —> 2x-6+4=10. next you would add like terms which would be -6 and 4: 2x-6+4=10 —> 2x-2=10. then you would subtract 2 from both sides: 2x-2=10 —> 2x=12. finally you would divide both sides by 2 and that would give you 6: 2x=12 —> x=6. to double check your answer you would replace x with 6 in the original equation. hopefully this helps.

The length of the base on an
isosceles triangle is 5x. The length of
a leg is 6x + 8. The perimeter of the
triangle is 107. Find the length of the
base.

Answers

Answer:

455/17 or 26 13/17

Step-by-step explanation:

Since the triangle is an isosceles triangle the legs are the same length.

2(6x+8) + 5x= Perimeter

12x+16+5x= Perimeter

Perimeter =107

17x=107-16

17x=91

x=91/17

Since we are trying to find the base which is 5x, we can substitute.

5*91/17= 455/17 or 26 13/17
