Answer:
<u>The minimum score Jasmine needs to make on the fifth test to ensure her average is at least 80% is 56%</u>
Step-by-step explanation:
This is the information provided to us to answer the question correctly:
- Score 1st test = 87%
- Score 2nd test = 92%
- Score 3rd test = 76%
- Score 4th test = 89%
- Score 5th test = x
Now, let's calculate the average of Jasmine's scores and to solve for x:
(87 + 92 + 76 + 89 + x)/5 ≥ 80
(344 + x)/5 ≥ 80
344 + x ≥ 80 * 5
344 + x ≥ 400
x ≥ 400 - 344
<u>x ≥ 56</u>
Answer:
all except the first
Step-by-step explanation:
Answer:
ages would no longer get larger as the mouse hovers over them. The transition would happen over 10s, since this is the default duration.
Step-by-step explanation:
You know that t=0 and x=0, the car starts moving with a constant acceleration of 2.70m/s²
At the same time, a truck moving speed o 8.50 m/s passes the car
D=v.t (for the truck)
And d= v.t+1/2.a.t²(for the car)
v.t=1/2.a.t²
t=2.v/a
t=2.8.50 m/s/ 2.70 m/s²
17m/2.70=6.29
This mean that the distance is
D=v.t=8.50m/s.6.29= 53.465 m/s
The speed of the car is
Vcar=a.t
2.7m/s2×× 53.65
=144.34
Answer:
B and C only show direct proportion
