Answer 1

Answer:

24.44 percent

Step-by-step explanation:

F=Friday

S=Saturday

P(F or S)= 20/90+22/90-20/90=22/90

22/90 as percentage is 24.44 percent

Answer 2

Answer:

For Friday, 22% of the check in's happened on that day. For Saturday, 24% of the check in's happened on that day. For both days combined, 46.66% of the check in's happened for both.

Step-by-step explanation:

Overall there were 90 check ins. Since 20 happened on Friday, it would be 20/90, which is 22%. Saturday, 22 check ins happened, so it would be 22/90, which is 24%. Overall, between Friday and Saturday, 42 check in's happened, so it would be 42/90, which is 46.66%.

Step-by-step explanation:

Basically, an exponential form is a number with an exponent. What's an exponent you may be asking, an exponent is that little number on the top left of a base number (aka the normal sized number there), what an exponent does it make that base number multiply by itself how many ever times it says. So for example, lets say our base number is 3 and our exponent is 4, we would have to multiply 3 by 3 4 times, like this: 3 x 3 x 3 x 3.

The expanded form is what I just did before, it just shows what the exponent is doing, like the 3 x 3 x 3 x 3 thing, that is the expanded form of 3⁴.

And lastly the standard form is just what we usually see it as, like the standard form for 3⁴ would be 81. I like to think of it as the answer to what ever that exponential form's expanded form is, the answer to 3 x 3 x 3 x 3 = 81.

Sorry if this seems very confusing, this is my first time answering a question here, so if you see any mistakes, please correct me.

Rebecca needs at least $130 to buy a new dress. She has already saved $58. She earns $8 an hour tutoring. Write and solve an inequality to find how many hours she will need to tutor to buy the dress.

Answers

Answer:

8x + 58 = 130

x = 9

Step-by-step explanation:

x = # of hours

8 dollars per hour.

So it will be 8x.

58 dollars saved so far.

So it will become 8x + 58 = 130

Because she needs 130 total

8x + 58 = 130

8x = 130 - 58

x = 72 / 8

x = 9

X=9 sorry I also need help with high school work

Kadesha says that the triangles represent a translation. Which explains whether Kadesha is correct?

A. Kadesha is correct because triangle ABC is the pre-image and triangle A' B' C' is the image.

B. Kadesha is correct because each point in triangle ABC moves five units up.

C. Kadesha is not correct because the number of units between points A and B is different than those between points A' and B'.

D. Kadesha is not correct because a translation is a horizontal movement.

Answers

Answer:

Step-by-step explanation:

C is correct because a translation is just a movement across the graph- but in this case, the shape has not just moved, but the space between the points has changed. In a translation, the shape does not change at all.

A computer repairman charged $720 to come visit a business, plus $45 per hour of work. During one week he earned $1,800. How many hours did the repairman work in that week?
A. 21
B. 24
C. 39
D. 40

Answers

Answer:

24 hours

Step-by-step explanation:

Hi,

The equation to represent this situation would be 45x + 720 = 1800

(45 is the cost per hour, x is the number of hours since you don't know how many hours that person was there for. 720 is there because no matter what, you have to pay 720 to visit and = 1800 is the total cost)

Now, solve for x.

45x + 720 = 1800

Subtract 720 on both sides...

45x = 1080

Divide by 45 on both sides...

x = 24

He worked 24 hours that week.

Hope this helps :)

he would have worked 24 hours :)
