For the first one the answer gotta be B Or C and the second one is B or A
Answer:
The sound takes time to go to a point and reflect back to your position.
It means the sound went twice a distance.
=> Suppose it takes about 0.5 seconds to hear the echo, the canyon wall would be [750 x (0.5/3600)]/2 = 0.052 miles
=> Suppose it takes about n seconds to hear the echo, the canyon wall would be [750 x (n/3600)]/2 miles
Hope this helps!

Answer:
She will need 3.5 pounds of cheese to make the 28 casseroles
Step-by-step explanation:
In this question, we are tasked with calculating the amount of cheese in pounds needed to make 28 casseroles.
In the revised recipe, she intends using 1/2 of what is supposed to be used in the original recipe. Mathematically, since each original casseroles is meant to take 4 ounces of cheese, the revised recipe taking half will have 1/2 × 4 = 2 ounces of cheese per casserole
Now for 28 casseroles based on the revised recipe, the total amount of cheese to be used mathematically is equal to 28 × 2 = 56 ounces of casserole
The questions asks that our answer be in pounds
Mathematically, 1 ounce = 0.0625 pounds
Hence, 56 ounces of casseroles will be 56 × 0.0625 = 3.5 pounds of cheese
Answer:
x = 5
Step-by-step explanation:

BD is already given to you as bisected. AC must also be bisected. That means that 6x and 7x - 5 must the the same value. Then and only then will the figure be a parallelogram. (a four sided figure is a parallelogram if the 2 diagonals are bisected.
Equation
6x = 7x - 5 Subtract 6x from both sides
Solution
6x - 6x = 7x - 6x - 5 Simplify
0 = x - 5 Add 5 to both sides
5 = x - 5 + 5 Simplify
x = 5
