Answer 1

Answer:

3.) 6 to 5

Step-by-step explanation:

Unit rates are like ratios. It also means a rate of one to something. So 3.) 6 to 5 is correct

Answer 2

The answer is 2. 60 miles per hour.
Unit rate is a ratio that compares two different quantities with different units.
Choice 2 is the only right one since it’s miles per hour. Choice 1 and 3 are just simple ratios with no units.

Find the selling price. Round to the nearest cent for each 18-20

18. cost: $10 percent markup: 50%

19. cost: $28 percent markup: 25%

20. cost: $65 percent markup: 70%

Answers

18: 15$

19: 35$

20: 110.50$

Step-by-step explanation:

18: A 50% markup would mean 5 dollars extra which makes it 15$

19: 25% of 28 would be an extra 7 dollars which makes it 35$

20: 70% of 65 would be 45.50 cents, adding this to 65 would make it 110.50$

A sculpture is made of solid nickel in the shape of a cone. The sculpture is 84 inches tall, and its base has a diameter of 16 inches. If nickel costs $2.25 per cubic inch, how much did the nickel for the sculpture cost?

Use 3.14 for pi, and do not round your answer.

Answers

The total cost of the nickel for the sculpture is $12,660.48.

We know that the volume of a cone is:

v = 1/3πr²h ......(i)

where r ⇒ radius of the cone

h ⇒ height of the cone

Now, as per the question,

r = diameter/2 = 16÷2 = 8 inches

h = 84 inches

Putting the values in equation (i)

v = 1/3 × 3.14 × (8)² × 84

v = 5626.88 cubic inch

The cost given for nickel = $2.25 per cubic inch

So, the total cost for the nickel used in making the sculpture:

the volume of cone × cost per cubic inch

5626.88 × 2.25 = $12,660.48

Therefore, the total cost for the nickel used is $12,660.48

Find the percent of change. Round your answer to the nearest tenth of a percent, if necessary.

Answers

Answer:Therefore, the percent change from 56 to 77 students is 37.5%.

Step-by-step explanation:

students, we can use the following formula:

percent change = ((new number - old number) / old number) x 100%

Plugging in the values given in the problem, we get:

percent change = ((77 - 56) / 56) x 100%

percent change = (21 / 56) x 100%

percent change = 0.375 x 100%

percent change = 37.5%

Therefore, the percent change from 56 to 77 students is 37.5%.

What is the area of this trapezoid?

Enter your answer in the box.

Answers

Answer:

153 units squared

Step-by-step explanation:

first, multiply 10 x9 to find the area of the rectangle, which is 90

then find the area of the triangle. The formula for area of a triangle is

A=1/2bh

so, 7 x 9= 63 divided by 2 is 31.5

since there are 2, multiply 31.5 x 2= 63

add 63 to 90 which is 153

Answer: 153 sq. units

Step-by-step explanation:

Base a = 10

Base b = 7x2 = 24

Height = 9

area of trapezoid = 1/2 * (a+b) * h

= 10+24 * 9 /2

= 306/2 = 153
