Answer:
a). x=18x2
18x2=36
Don spent 36 dollars.
b). x=36x0.3
36x0.3=10.8
Brad's sister spent 10 dollars and 80 cents.
c). 36+18=54
1.0-0.13 = 0.87
54x0.87=46.98
54-46.98=7.02
Don and Brad paid 7 dollars and 2 cents in tax.
12 is an even number
so that’s the answer
9514 1404 393
Answer:
176.5%
Step-by-step explanation:
The percentage change can be computed from ...
percent change = ((new value)/(old value) -1) × 100%
= (58429/21129 -1) × 100%
= (2.7653 -1) × 100%
percent change ≈ 176.5%
_____
<em>Additional comment</em>
The average annual increase can be found by taking the root of the ratio, where the root index is the number of years. The percentage increase each year is that root less 1.
(2.7653^(1/(2019 -1996)) -1 ≈ 4.5% . . . per year for 23 years
The figure that accompanies the question shows Carlos at point K on the roof of the building, the line KL as the horizontal line, and the car at point I on the street, on the horizontal line HPIJ.
The depression angle is the angle below the horizontal line passing through Carlos (KL) and the line from Carlos to the Car (KI).
So the vertices that define the depression angle are LKI and the depression angle requested is named LKI.
Answer: angle LKI.<span>
