Answer:
The donuts cost $0.75 and the cookies cost $0.6
Step-by-step explanation:
You need to create a system of equations:
20d + 30c = 33
5d + 2c = 4.95
Now, let's isolate the cookies on the second equation:
2c = 4.95 - 5d
Multiply it per 15 to get the value of 30 cookies:
30c = 74.25 - 75d
Substitute in the first equation:
20d + 74.25 - 75d = 33
-55d = -41.25
d = -41.25/-55
d = 0.75
Now substitute the value of d in the second equation to find the value of c:
5•0.75 + 2c = 4.95
3.75 + 2c = 4.95
2c = 4.95 - 3.75
2c = 1.2
c = 1.2/2
c = 0.6
Πr²h(2)-πr²h(1)=πr²(h(2)-h(1))=V2-V1
V2-V1=πr²(h(2)-h(1))
314-188.4=π*2²(h(2)-h(1))
(h(2)-h(1))=(314-188.4)/4π=10
difference is 10 cm
GCF;
18 = 1, 2, 3, 6, 9, 18
24 = 1, 2, 3, 4, 6, 8, 12, 24
the GCF is 6. so divide both numerator and denominator by 6 to find the simplest form.
18/24
18 ÷ 6/ 24 ÷ 6
3/4
hope this helps, God bless!
