Answer:
5 bags of cement are required.
Step-by-step explanation:
Since to make concrete, the ratio of cement to sand is 1: 3, if cement and sand are sold in bags of equal mass, to determine how many bags of cement are required to make concrete using 15 bags of sand the following calculation must be done:
Cement = 1
Sand = 3
3 = 15
1 = X
15/3 = X
5 = X
Therefore, 5 bags of cement are required.
The answer is 14. The two lower angles are 50 each 100 total and so the top angle must equal 80. If you set it equal to 80 you get 14.
Well Those are variables and it is using the Distributive property to solve. For example P(a+b) simplify P*a + P*b.
Answer:
(this isnt a mathematics question, it's science, btw)
Indeed, you are correct. It is 1. I think.
Because you get one allele from each parent, to make up 2 alleles per offspring.
Hope that helps!
Answer:
C
Step-by-step explanation:
A triangle is 180 degrees so 120+40 is 160
