Answer:
23 more cubes
Step-by-step explanation:
If it's 2 times as long, the length is 2
If it's 3 times as wide, the width is 3
It it's 4 times as high, the height is 4
2 · 3 · 4 = 24, which is 23 more than 1
D) perpendicular!
A perpendicular's definition is: a straight line at an angle of 90° to a given line, plane, or surface.
And if you mark them on a graph you could see these two are opposite of each other.
Answer:
12 dimes and 18 nickels
Step-by-step explanation:
Equations given by word problem:
n + d = 30
0.05n + 0.1d= 2.10
How I solved them:
d= 30 - n
0.05n + 0.1(30 - n)= 2.10
0.05n + 3 - 0.1n= 2.10
-0.05n= -.09
Divide both sides by -0.05
n= 18
18 + d = 30
d= 12
B is the answer because none of the others will be right and b is the one you should always do when to solve a rea word problem
