Answer:
The product is 1.4
Step-by-step explanation:
Every time you multiply 0.2 by a number, add 0.2 to the previous number.
0.2 x 1 = 0.2
0.2 x 2 = 0.4
0.2 x 3 = 0.6
0.2 x 4 = 0.8
0.2 x 5 = 1.0
0.2 x 6 = 1.2
0.2 x 7 = 1.4

Answer:
A) h = 4
B) k = 6.5
Step-by-step explanation:
In each case, the midsegment is half the length of the parallel base segment.
A) FG = 2KJ
(4h -8) = 2(h)
2h = 8
h = 4
__
B) GH = 2LK
4h -3 = 2k
(4(4) -3)/2 = k = 13/2 = 6.5
Answer:
First we found the sum of 15.438 and 3.18. The subtract the answer from 32.476.
Option A is correct.
Step-by-step explanation:
The total width of box is = 32.476
Width of box of T-shirts = 15.438
Width of box of Socks = 3.18
We need to find width of coat box.
The width of coat box can be found as:
Total Width = Width of box of T-shirts + Width of box of Socks + width of coat box
32.476 = 15.438 + 3.18 + width of coat box
32.476 = 18.618 + width of coat box
width of coat box= 32.476 - 18.618
width of coat box = 13.858
So, The Width of coat box = 13.858 inches
First we found the sum of 15.438 and 3.18. The subtract the answer from 32.476.
Option A is correct.
Answer:
The bus route from Springfield to Burlington is 172.5 miles long.
Step-by-step explanation:
Let the distance of the bus route be x.
Distance covered by bus from Springfield to Burlington = x
Distance covered by bus from Burlington to Springfield = x
Distance covered in 1 round = x + x = 2x
Total distance covered by bus in 9 round = 9 × 2x = 18x
Given that bus traveled a total distance of 3,105 miles
![18x=3,105 miles](https://tex.z-dn.net/?f=18x%3D3%2C105%20miles)
![x=\frac{3,105 miles}{18}=172.5 miles](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B3%2C105%20miles%7D%7B18%7D%3D172.5%20miles)
The bus route from Springfield to Burlington is 172.5 miles long.
