Complete Question:
Triangle abc has the angle mesausres shown.
m<A = (2x)°
m<B = (5x)°
m<C = (11x)°
Which statement is true about the angles?
A. m<A = 20°
B. m<B = 60°
C. m<A and m<B are complementary
D. m<A + m<C = 120°
Answer:
A. m<A = 20°
Step-by-step explanation:
m<A + m<B + m<C = 180° (sum of interior angles of a triangle)
(substitution)
Solve for x. Add like terms.
Divide both sides by 18
Find the measure of each angle by substituting x = 10:
m<A = (2x)° = 2(10) = 20°
m<B = (5x)° = 5(10) = 50°
m<C = (11x)° = 11(10) = 110°
Therefore, the only true statement is:
A. m<A = 20°
First of all we need to formulate two equations.
x = monthly fee per minute
y = monthly fee per minute over 500
500x + 130y = $53.55
500x + 209y = $63.03
Since we know that 500x = $53.55 - 130y we can substitute.
($53.55 - 130y) + 209y = $63.03
79y = 9.48
y = $0.12
Now we can substitute y into the other equation.
500x = $53.55 - 130(0.12)
500x = $53.55 - $15.6
500x = $37.95
So the answer is $37.95 monthly for 500 minutes with an over quota fee of $0.12 per minute.
Alright, so we have a max of 20,000 kg. There is already 4000 on it, so we can subtract 4000 by 20000 to get 16000. We need to figure out how many times 1500 goes into 16000 to figure out the cubic meters, which is 16000/1500=10+2/3
90 feet/5 minutes = 18 feet per minute
Answer:
98
Step-by-step explanation:86+86=172
368-172=196
196/2=98
