Answer: 4.8 ft
To answer this question you need to know how much shadow: actual height ratio. Flagpole is having 8 ft shadow with 20 ft actual height. The ratio should be= 8 ft: 20 ft= 0.4
Then multiply the ratio with the oak tree shadow. The equation would be:
0.4 x 12 ft= 4.8 ft
Answer:
About 1 gallon. (32/30)
Step-by-step explanation:
First get a LCM (least common multiple) for 3, 5, and 2.
Now we have 30. Make 30 the denominator for all.
10/30
15/30
7/30
Then add them all up to get 32/30.
About 1 gallon.
13. 1,6
18. -15,12
19. -7, 1/2
The 2 angles are complementary angles and need to equal 90 degrees.
Making an equation we have:
4x-10 + x = 90 degrees
Add like tems:
4x +x = 5x
Now we have:
5x-10 = 90
Add 10 to both sides:
5x = 100
Divide both sides by 5:
x = 100/5
X = 20
M = Y / X
m = [1 - (-2) ] / [2 - (-2)]
m = (1+2) / (2+2)
m = 3 / 4
Using (2,1)
y - yo = m (x-xo)
y - 1 = 3/4 (x-2)
Or
(-2,-2)
y + 2 = 3/4 (x+2)
