Answer:There are two right triangles. You need to find the opposite side (the height) of each of them. The difference between the two is the height of the blade, x.
You know the adjacent, 440, and you are looking for the opposite, so you need to use tan for both.
tan (30) = y / 440
y = 440 * tan (30) = 254.034...
tan (38.8) = z / 440
y = 440 * tan (38.8) = 353.769.--
353.8 - 254.0 = 99.8 = 100 feet.

Answer: 9
Step-by-step explanation:
An elf ate 15 of your muffins and that was 5/8 of all of them. To get the number of muffins left goes thus:
We can first calculate the total number of muffins the person had. Let the total number of muffins be y. That means the elf ate 5/8 of y.
5/8 of y = 15
5/8 × y = 15
0.625 × y = 15
0.625y = 15
Divide both side by 0.625
0.625y/0.625 = 15/0.625
y = 24
The total amount of muffins is 24. Since the elf has eaten 15, the amount left will be: 24-15 = 9
Answer:
It equals a negative number because there's a negative and a positive which will result in a negative answer
Step-by-step explanation:
if there's a negative and a positive the result will be negative
if it's two negative result would be positive :
-1 × -1 = +1
-1 × +1 = -1
+1 × +1 = +1
-1 × -1 × -1 = -1
-1 × -1 × +1 = +1
Answer:
x=7
Step-by-step explanation:
5x-9=8x-30
8x-5x=-9+30
3x=21
x=21/3=7
