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
Answer:
421/6 degrees
Step-by-step explanation:
The acute angles of a right triangle are complementary, so

So, the acute angles measures 421/6 degrees and 119/6 degrees, and thus the larger angle is 421/6 degrees.
Answer:
1/ 5 and 2/3
cross multiple
example
1 2 = 10
/ x / = /
5 3 3
= 10/3
so it's 3 1/3 + 10 Mm
so may guess is
13.3333 infinite or 13.34 M
Dont know if its right but good luck
