A mason is a person who builds structures with bricks, stone, cement block, or tile. A mason usually uses mortar to hold the bricks together. A general rule of thumb in masonry is that 2 1/2bags of mortar are

a. Complete a double number line to determine the amount of mortar needed for each quantity of
blocks.
b. How many bags of mortar will a mason need for 350 blocks?
c. How many bags of mortar will a mason need for 50 blocks?
d. With 12 bags of mortar, how many blocks can the mason lay?

I think it can be D

hopfully this helps :)

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
