Answer:
350 meters cubed.
Step-by-step explanation:
If you visualize it, there are two rectangular prisms: one flat one on the top, and one large one on the bottom.
The width of the top one is 5 meters. The length is 7 meters. The height is 8 - 5 = 3 meters. So, one prism has a volume of 5m x 7m x 3m.
The width of the bottom one is 7 meters. The length is 7 meters. The height is 5 meters. So, the bottom prism has a volume of 7m x 7m x 5m.
(5 * 7 * 3) + (7 * 7 * 5)
= (35 * 3) + (49 * 5)
= 105 + 245
= 350
So, the volume of the figure is 350 meters cubed.
Hope this helps!
Answer:
6 hours
Step-by-step explanation:
First set up the equation. Seeing the word "per", we know that this will be the variable. The repairman charges an initial fee of 37.50, so we add that fee to the total cost of every hour. To find how much Robin can spend, you set it equal to 450
65x + 37.50 = 450
Now subtract 37.50 from both sides because neither number has a variable, so you can subtract them to simplify the equation
65x = 412.5
To isolate x and find what it's equal to, divide both sides by 65 to get rid of the coefficient.
x = 6.34.
However the answer should be 6 because robin cannot afford a full or part of a 7th hour
Answer:
(3m - 2) + (2m + 7) + (5m - 3)
Step-by-step explanation:
Perimeter is found by combining all side measurements together to find the total measurement. In this case, combine the sides:
(3m - 2) + (2m + 7) + (5m - 3) is your answer.
If you need a simplified expression, simply combine all the like terms together. Like terms are terms with the same as well as same amount of variables:
(3m + 2m + 5m) + (7 - 2 - 3)
(10m) + (2)
10m + 2 is your answer.
~
-6r+5
the two like terms are the ones with R. combine -4r and -2r to get -6r
