Well r equals what ever number same for the c then what numbers you get from those 2 add to the p
Answer:
7.5kg
Step-by-step explanation:
Given that:
Monday:
Mass of sand = 24 kg
Mass of cement = 5 kg
Tuesday :
Mass of sand = 36 kg
Let mass of cement = c
Mass of cement required to make the same type of mortar mix
Mass of Sand = mass of cement
24kg = 5kg
36kg = c
By cross multiplication :
24 * c = 5 * 36
24c = 180
Divide both sides by 24
c = 180 / 24
c = 7.5 kg
Hence mass of cement required is 7.5 kg
V=(h)(pi)(r^2)
say pi=3.14
h=15
d/2=r=4/2=2
so
v=(15)(3.14)(2)^2
v=(15)(3.14)(4)
v=(60)(3.14)
v=188.4
so answer is D
Given that the loan is paid for 24 months or 2 years and the interest rate is 2.75% which is $650. In order for us to find the amount that Dr. Jones borrowed, let us put it this way. ? x 0.0275 = 650. So we divide 650 by 0.0275 and the answer is 23,636.36. Hope this answers your question.
