45(x)-20
x=hours
7 hours
x=7
45(7)-20 =295
Answer:
y = 45(7) - 20
Step-by-step explanation:
Money earned: 45x.
Money spent: 20
Total money: 45x-20
In this case, if he worked 7 hours, he would make a total of 45(7)-20, or 295 dollars for the day.

The point (7, 0) is reflected over the x-axis. What do you notice about the coordinates of the reflected point? Why is this?
Answer:
The coordinate stayed the same
Step-by-step explanation:
because when you reflect on the x-axis, the x-axis stays the same while the y-axis gets flipped. in this case, the coordinate is on the y-axis, or the y-axis is 0, and you can't flip 0 to get an opposite. the opposite of 0 is 0, so he coordinate stayed the same.
The value of reflected point is, (7, 0)
And, Any point on the line of reflection is invariant
What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
The point (7, 0) is reflected over the x-axis.
Hence,
The point (7, 0) becomes the point (7, 0) when reflected over the x-axis. That is, its coordinates do not change.
And, The point (7, 0) lies on the x-axis, so is on the line of reflection. Any point on the line of reflection is invariant--it doesn't move.
Hence, The transformation for reflection in the x-axis is ...
(x, y) ⇒ (x, -y)
(7, 0) ⇒ (7, 0) . . . . . . the opposite of 0 is 0
Thus, The value of reflected point is, (7, 0)
And, Any point on the line of reflection is invariant

Look at Figure 2. What is the measure of x ? ( Hint: you may need to use triangle ACE to help you;) notice the right angle??? NEED HELP ASAP PLEASE
Answer:
60°
Step-by-step explanation:
Let angle BAE = angle ACD = x
BCD = AEC = 60°
EAC + FCA + ECF + AEC = EAC + x + 60° + 60° = 180°
EAC = 60° - x
BAC = EAC + BAE = 60° - x + x = 60°

Find the volume of the sphere. Either enter an exact answer in terms of π or use 3.14 for π and round your final answer to the nearest hundredth.
Answer:
33.49
Step-by-step explanation:
The formula for volume of a sphere is 4/3 × π × radius³
The radius in this case is 2
2³ = 8
4/3 × 8 = 10 2/3
10 2/3 × 3.14 ≈ 33.49
You can also right it as (10 2/3) × π

Answer:8
Step-by-step explanation:
The prime factors of 24 are 2*2*2*3
The prime factors of 40 are 2*2*2*5
They both share 2*2*2
2*2*2=8
the factors of 48 are 1,2,6,8,12,24,48
the greatest common factor of 60, 84 and 72 is 12
solution
12 times 4 equals 84; 12 times 5 equals 60
the factors of 36 are : 1,2,3,4,6,9,12,18,36
factors of 54 are : 1,2,3,6,9,18,27 and 54
