Answer:
Your answer is B
Step-by-step explanation:
*If you use 3.14 for pi*
C = 2*pi*r
C = 2*3.14*9
C = 56.52
The 2nd one is right
112.5 divided by 15 is 7.5
Let's call:
M = necklaces owned by Mary Sue
B = necklaces owned by Betty
You know that:
M + B = 603
M - B = 115
Therefore, when you have the sum and the difference of two numbers, in order to find the biggest number you have to sum the sum and the difference and divide it by 2, and in order to find the smallest number you have to subtract the difference from the sum and divide it by 2:
M = [(M + B) + (M - B)] ÷ 2
= [603 + 115] ÷ 2
= 359
B = [(M + B) - (M - B)] ÷ 2
= [603 - 115] <span>÷ 2
= 244

Hence, Mary Sue has 359 necklaces and Betty has 244 necklaces.

Answer:
5.1cm
Step-by-step explanation:
volume of hemisphere = 1.07cm³
9.2-1.07 = 8.13
volume of cylinders = 8.13cm³
height of cylinder = 4.04cm
total height of gizmo = 4.04+0.8=4.84
4.84/sin(72) = 5.1cm
