Answer:
Step-by-step explanation:
.72x+3=0.3(2.4+15)
.72x+3=0.72+4.5=0.72+4.50
.72 x=5.22

Answer:
100°
Step-by-step explanation:
The angle between chords is the average of the intersected arc angles.
∠FKJ = ½ (84° + 76°)
∠FKJ = 80°
∠HKJ is supplementary to ∠FKJ.
∠HKJ = 180° − 80°
∠HKJ = 100°
8r(40)=4
r=1/80 that is the rate for each person...
10rt=7 using r we found before
10(1/80)t=7
t/8=7
t=56 minutes.
Answer:
My answer would be B.
Step-by-step explanation:
Triangle angles have to add up to a total of 180 degrees. B. has a very close measures in angles. I am sorry if this is not the answer. But let me know.
Answer:
A Sarah earns more money per hour $15
Step-by-step explanation:
We need to find the slope to determine the rate ( amount per hour
Sarah
m = (y2-y1)/(x2-x1)
= (50-5)/(3-0)
= 45/3
= $15 per hour
Mia
m = (y2-y1)/(x2-x1)
= (20-10)/(2-0)
= 10/2
= $5 per hour
