Amy is having her birthday party at a skating rink. The rink charges $50 plus $8 per person. If Amy wants to spend at most $200, how many people can she invite? (Hint: make sure you include Amy in the head count.)

Answers

Answer:

18

Step-by-step explanation:

Amy can invite 18 people (including herself). $200-$50=$150. $150÷8=18.75. You can't have 18.75 people so you round it down to 18. Hope this helps!

Answer: 18 people including herself

Step-by-step explanation: Take $200-$50=$150

now divide 150 by 8 which is 18.75 you obviously can't round up so you round down to just 18 and thats your answer. she can have 18 people there including herself

A real estate agent has sold a house for $350,000. She earns 3% commission. How much did she earn? Show your work!

Answers

3% is equal to .03 so .03 times $350,000 equals $10,500

Well, let’s get started! The major here is dollars and percentages. Let’s have a look: 350,000/100%. Do you know why? 350,000 is the total, which is 100%. The seller only earns 3%. So let’s compare:

350,000          ?

————-        ——-

100%                 3%

Now we do 350,000 times 3. This is because ? Times 100 is equal to 350,000 times 3. 350,000 time 3 is 1,050,000. Now we do 1,050,000 divided by 100. This equals 10,500.

10,500 is your answer

36. Find the side length of a cube whose surface area is 10848 cm2.

Write your answer to 2 decimal places.

Answers

Answer:

Step-by-step explanation:

Surface area of cube = 10848 square cm

6a² = 10848

Divide both sides by 6

a² = 10848/6

a² = 1808

a = √1808

a = 42.52 cm

The diameter of a bicycle wheel is 16 inches. How many revolutions will it take the wheel to travel about 192 inches?

a.8
b.4
c.1
d.16

Answers

Answer:

its actuly 12

Step-by-step explanation:

16x12=192

The number of revolutions it takes the wheel to travel about 192 inches is 4. Therefore, option B is the correct answer.

What is circumference of a circle?

The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. The circumference of a circle is the product of the constant π and the diameter of the circle.

Given that, the diameter of a bicycle wheel is 16 inches.

We know that, the radius of a circle is diameter/2

Here, radius of bicycle wheel =16/2 =8 inches

As we know, the circumference of a circle is 2πr

Now, circumference of bicycle wheel is

2×3.14×8

= 50.24 feet

The wheel to travel about 192 inches

Number of revolutions =192/50.24

= 3.82

≈ 4

The number of revolutions are 4. Therefore, option B is the correct answer.
