Multiply the number of hours worked (h) by earnings per hour $10 to get
10h
This needs to be more than ( Greater than) 200
Now you have 10h > 200
Solve for h by dividing both sides by 10:
h >20
This means she needs to work more than 20 hours this week.
Answer:
10h=200
h=20
Step-by-step explanation:
10h=200
10h/10=200/10
h=20
B.5.0m/s
C.10m/s
D.15m/s
The vehicle's acceleration if its value may b assumed to be constant is 10 m/s. Therefore, option C is the correct answer.
Given that, a vehicle designed to operate on a drag strip accelerates from zero to 30m/s while undergoing a straight line path displacement of 45m.
Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction-or change both.
Here, Δx = 45 m, v₀ = 0 m/s and v = 30 m/s
Using the formula v² = v₀² + 2aΔx
(30 m/s)² = (0 m/s)² + 2b (45 m)
b = 10 m/s
The vehicle's acceleration if its value may b assumed to be constant is 10 m/s. Therefore, option C is the correct answer.

Answer:
C. 10 m/s²
Step-by-step explanation:
Given:
Δx = 45 m
v₀ = 0 m/s
v = 30 m/s
Find: a
v² = v₀² + 2aΔx
(30 m/s)² = (0 m/s)² + 2a (45 m)
a = 10 m/s²
Answer:
No.
Step-by-step explanation:
If (0,5) is a solution to y=2x, then 5=2(0) has to be true.
It is not because 5=2(0) is not true.
2(0)=0 and 0 is definitely not 5.
An example of a point on y=2x is (5,10) since 10=2(5) is true.
Answer:
No
Step-by-step explanation:
The coordinate points are x and y.
So, in this case, 0 would be x and 5 would be y.
We can substitute those numbers into our equation to get:
5=(2)(0)
2 multiplied by 0 equals 0.
0 CANNOT equal 5.
Therefore, your answer is NO, (0,5) isn't the solution to the equation y=2x.

Answer:
The upper bound of the interval is below 0.5, which means that it can be claimed that a majority of people are not in favor of legalized abortion
Step-by-step explanation:
Confidence interval:
Sample proportion plus/minus margin of error.
In this question:
Sample proportion of 0.45, margin of error of 0.04. So
0.45 - 0.04 = 0.41
0.45 + 0.04 = 0.49
The confidence interval is of (0.41,0.49). The upper bound of the interval is below 0.5, which means that it can be claimed that a majority of people are not in favor of legalized abortion
Given the margin of error of 4 percentage points, we cannot definitively state that a majority are against legalized abortion, even though the survey shows a 45% favor rate. The true proportion could be anywhere from 41% to 49%.
The question relates to the interpretation of survey results and margin of error. The study indicates that 45% of the surveyed adults favor legalized abortion, down from 55%. However, the study also reveals a margin of error of 4 percentage points.
This implies that the true proportion of adults favoring legalized abortion could be anywhere from 41% (45% - 4%) to 49% (45% + 4%). So, we cannot definitively say that a majority of adults are opposed to legalized abortion, as the result could still be close to 50%, given the margin of error.
