In a right triangle, the measure of one acute angle is 30 less than twice the measure of the other acute angle. Find the measure of each angle.
---
The sum of the 2 acute angles is 90 degrees.
x + y = 90
x = 2y-30
----
Substitute for "x" and solve for "y":
2y-30 +y = 90
3y = 120
y = 40
x = 90-y
x = 90-40
x = 50
We have the equation for company 1: y = 3x + 5. That means it costs $3 to rent a movie with a $5 fee no matter how many movies you rent. It would benefit us to have the equation for company 2, so we need to find it using 2 points on the line. I picked the points (2,14) and (0,12). Find the slope of this by using the slope formula:

which gives us a slope of 1. Now we can use that slope and the slope-intercept form of a line to find the y-intercept, which serves as the fee for renting from company 2. 14=1(2)+b and 14 = 2 + b and b = 12. The equation then for company 2 is y=1x+12. This means it costs $1 to rent movies, but your fee to rent, no matter how many movies you pick, is $12. The "rate of change" in the choices refers to the slope. The slope in company 1's equation is 3 and the slope in company 2's equation is 1. The best description is the first choice that says "There is a higher rate of change at Company 1".
The correct answer is D hope this helps
Answer:
see below
Step-by-step explanation:
The total number of trees is
567+324+156+89+678 =1814
Percent fir = 567/1814 = .312568908=31.26 %
Percent pine = 324/1814 = .178610805=17.86%
Percent larch = 156/1814 =.085997795=8.60%
percent cedar = 89/1814 =.049062845=4.91%
Percent hemlock = 678/1814 = .373759647=37.38%
The total should be 100 %
31.26+17.86+8.60+4.91+37.38=100.01 ( rounding error because we rounded to the hundredths place)
It would be A) 1.01
Specifically, it measures 1.0056
