Answer:
-5
Step-by-step explanation:
There was five inches of snow, correct? Now, the five inches are melting. It's kinda like subtraction.
5 - 5
The average of the first three is 83 (85 + 90 + 74)/3
The average of the next 3 is 86.
The difference is 3
1. The formula for the area of a rectangle is:
A=LxW
L: The lenght of the rectangle (L=2W).
W: The width of the rectangle.
2. Let's substitute L=2W into the formula A=LxW:
A=LxW
A=2WxW
A=2W²
3. When we clear "W", we obtain:
W²=A/2
W=√(A/2)
4. We already know the value of "A", so:
W=√(50 ft²/2)
W=√(25 ft²)
W=5 ft
5. Now, we must substitute the value of "W", into L=2W:
L=2W
L=2(5 ft)
L=10 ft
6. The perimeter of a rectangle is:
P=2L+2W
7. We know the value of "L" and "W", therefore:
P=(2x10 ft)+(2x5 ft)
P=20 ft+10 ft
P=30 ft

The answer is: 30 ft
Let's simplify step-by-step.
6+4h+3
Combine Like Terms:
=6+4h+3
=(4h)+(6+3)
=4h+9
Answer:
=4h+9
Answer:
Step-by-step explanation:
Recall the mnemonics SOH-CAH-TOA
The sine ratio is the length of the opposite side expressed over the hypotenuse.
Take the sine inverse of both sides to get;
The cosine ratio is the length of the adjacent side expressed over the hypotenuse.
Take the cosine inverse of both sides to get;
