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
The slope is 3, so if x changes by 2, y changes by 6.
Answer:
diameter = 4
Step-by-step explanation:
A=pi*r^2
12.566=pi*r^2
3.99988202979=r^2
r=1.99997050723
diameter = 2r
d=2(1.99997050723)
d=3.99994101446 =4
Answer:
x ≥ 0
Step-by-step explanation:
The absolute value of something will always be the same number if the number is positive. Therefore, the values of x which make this true are x ≥ 0.
