Answer:
4 altogether
0,1 + 1, 1 = 1 RA
0,1 + 2,1 = 1 RA
0.2 +1, 2 = 1 RA
0,2 +2,2 = 1 RA
Step-by-step explanation:
30 is 20% of the number 150
25 is equal to 20% of 125
As the increase is 75 (200-125), you've then got to divide the increase by each part to find out how many times it increases.
75/25= 3
20*3= 60
Therefore, there is an increase of 60%
Hope this helps :)
Answer:
B. -3 and 2/3
Step-by-step explanation:
One way to see the constants is to set the variables to zero. What's left is ...
-3 + 2/3
These are the constants in the expression.
Answer:
A. 162
B. 128
Step-by-step explanation:
We have wooden cubes of 2 in of side.
A. If the box is 18 x 12 x 6 in., in the base (18 x 12), we can fit 54 cubes:

As the height is 6 in, we can fit 6/2=3 layers of 54 cubes in the box, se we can fit 162 cubes:

B. If we have a box with measures 16 x 9 x 9 in., and the base is 16x9 in, we can fit (16/2)*(9/2)=8*4=32 cubes per layer.
Note that in the 9 in side we can only put 4, as we need 10 in to fit 5 cubes (we can not cut them).
In the same way, as we have 9 in of height, we can fit 4 layers of 32 cubes, so this is a total of 128 cubes:
