Answer:
y = 1/5x + 8
Step-by-step explanation:
slope = (change in y)/(change in x)
Slope = (8 -10)/(0 -10)
Slope = -2/-10
Slope = 1/5
Use y = mx + b substitute m = 1/5 and (0, 8)
8 = 1/5(0) + b
8 = 0 + b
8 = b
The equation of the equation y = 1/5x +8
Reduced by 55%
100=original
100-55=45
45% of oiriginal=29.99
percent means parts out of 100
45%=0.45
0.45 of original=29.99
divide both sides by 0.45
original=66.644444444444444444444444444444
round
$66.64 is original price
Answer:
Step-by-step explanation:
We can form a right triangle using the plane, the airport, and ground and use basic trig for a right triangle to solve this problem.
In a right triangle, 
. Therefore, we have the following equation, where 
is ground distance between the plane and the airport:
.
Step-by-step explanation:
Let alpha be the unknown angle. We can set up our sine law as follows:
or
Solving for alpha,
7/4 ÷ 8/7
To divide fraction multiply the first fraction by the reciprocal of the second fraction:
7/4 x 7/8 = (7x7) / (4x8) = 49/32
