Answer:
10 feet higher.
Pine tree measure = 40 feet in height
Step-by-step explanation:
This is because the Flag pole of 50 feet in measure cast a shadow of 15feet and nearby to the pine tree (meaning same dilation would occur for such shadow) where pine tree shadow is given measure of 12 feet.
Flag Pole multiplier = 50 / 15 = 3 1/3
Pine Tree true measure = 12 x 3 1/3 = 40 feet in height
Answer:
88
Step-by-step explanation:
6 + 5 = 11
8 ÷ 2 = 4
11 · 4 = 44
44 · 2 = 88
The equation f(t) = -16t² + 176t is a quadratic equation, and so its maximum must be found at its vertex. In order to get this, you can use the formula
t = -b/2a.
Substituting, we have:
t = -176/2(-16) = 5.5 seconds.
But this is just only the time needed for the flare to reach its maximum height. To solve for the time the flare has been in the air, we multiply the maximum height by 2.
2 x 5.5 seconds = 11 seconds.
Answer:
The simple interest earned in one year is $10.5
Step-by-step explanation:
Simple interest = p × r × t
Where,
p = principal
r = interest rate
t = time
Principal= $350
Interest rate = 3%
=3/100
=0.03
Time= 1 year
Simple interest = p × r × t
= $350 × 0.03 × 1
= $10.5
The simple interest earned in one year is $10.5
