For 300 cubic feet, they will pay 5.56$ and there will still be 500 cubic feet.
if 100 cubic feet cost ............. 1.74$
500 cubic feet cost...............x
x=5*1.74=8.7$
Final amount = 8.7+5.56=14.26$
Final answer B.<span>$14.26</span>
Answer:
Martina is 53 inches tall.
Step-by-step explanation:
In order to write an expression that relates the siblings heights we need to attribute variables to each brother. First we will call Martina's height as "m", then we can call her little brother's height as "b". The problem states that Martina's height is 3 inches less than twice the height of her brother so we have:
m = 2*b - 3
Then the problem gives us the height of her brother that is 28 inches tall, so b = 28. We can now compute Martina's height:
m = 2*28 - 3 = 56 - 3 = 53 inches.
Using first the customary ruler and then the metric ruler, measure the length of the side of the wooden block. Remember to estimate to one place value beyond the rulers’ gradations.
