Actual length / shadow ratio is equal
Let the height of the building be x, then
36/28 = x/70
x = (36 x 70)/28 = 2,520/28 = 90.
Therefore, the height of the building is 90 feet.
Answer:
x=5.2
Step-by-step explanation:
8x−14=7.7x+3x
Step 1: Simplify both sides of the equation.
8x−14=7.7x+3x
8x+−14=7.7x+3x
8x−14=(7.7x+3x)(Combine Like Terms)
8x−14=10.7x
8x−14=10.7x
Step 2: Subtract 10.7x from both sides.
8x−14−10.7x=10.7x−10.7x
−2.7x−14=0
Step 3: Add 14 to both sides.
−2.7x−14+14=0+14
−2.7x=14
Step 4: Divide both sides by -2.7.
−2.7x
/−2.7 =
14
/−2.7
x=−5.185185 or 5.2
Answer:
B: 6 to the 10th over 7 to the 6th
Step-by-step explanation:
(6^5 / 7^3)^2
We know that (a /b) ^c = a^c / b^c
(6^5)^2 / (7^3)^2
We know that a power to a power is the powers multiplied a^b^c = a^(b*c)
6^ (5*2)/ (7^(3*2))
6^10/(7^6)
Since the bases are not the same, there is nothing else we can do
