Answer:
31 and -31
Step-by-step explanation:
Answer:
65 dm and 52 dm
Step-by-step explanation:
If the scale factor of the sides is k, then the scale factor of the areas is k^2.
The scale factor of the areas is (32 dm^2)/(50 dm^2) = 0.64 = k^2
The scale factor of the sides is k = \sqrt(0.64) = 0.8
The perimeters are in a ratio of 1:0.8
x + 0.8x = 117
1.8x = 117
x = 65
0.8x = 0.8(65) = 52
The perimeters are 65 dm and 52 dm.
Step-by-step explanation:
you first need to know what is mean .mean is when you add all the numbers up then divide them by 2
Answer:
It would be Square root of 38, and square root of 44 because they are all between 5 and 10. I'm sure you don't need their exact values, but that's them.

Answer:
The equation that best describes the situation is:
Step-by-step explanation:
The initial amount of gravel is g.
Then we know that 400 pounds are added
Two orders of 900 pounds are sold and the gravel is removed from the mound. This is:
At the end of the day, the mound has 1,500 pounds of serious. This is:
The equation that best describes the situation is:
And
