Order of Operation

10) An electrician charges $45 per hour and spends $20 a day on gasoline. If he worked for seven hours, write an algebraic expression to represent his earnings for the day.

Answers

Answer 1

45(x)-20

x=hours

7 hours

x=7

45(7)-20 =295

Answer 2

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.

Let me know if this  helps!

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

Answers

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°

x=60° because of the reflection, hope this helps :)

The point (7, 0) is reflected over the x-axis. What do you notice about the coordinates of the reflected point? Why is this?

Answers

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

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.

Answers

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

the formula for circumference is 2**r. so plug in the radius and it will be 2**3. that equals 6. I am not sure whether for your problem you’re supposed to multiply it by rounded pi, so the following answer is what you would get if you multiplied by pi, rounded. Now is infinite so we round it to 3.14. then multiply 6 by 3.14 and get 18.84 cm.
