Step-by-step:

Dozen flyers:price

4:7.25

12:x

To solve this mulitply 7.25 by 3 (because this is what we multiplied 4 by to get 12) 7.25*3=21.75

Question 2:

We can write teh following equation

.49+.22(x-1)=price

This is essentially saying that we pay .49 for the first ounce and .22 for every ounce after that

We can plug in an x value to get

.49+.22(5-1)

.49+.22(4)

.49+.88

1.37

Question 3:

We can write the following equation

x+2=y

We need to find out what happens when x=8

8+2=10

Question 4:

We can solve this with ratios

x:y

1.5:4.5

5:x

To solve just multiply 4.5 by 10/3 and get 15

We can just multiply

Answer:

1. 7.25/4=1.8125 so 1.8125x12=21.75

2. 0.49+(0.22x4)=1.37

3. rule is x+2=y so x=8 then y=10

4.rule is 3(x)=y so x=5 then y=15

A cone has the height 14 centimeters and base with the circumference or 8.4 pi centimeters. What is the volume of the cone in terms of pi.

19.6pi cubic cm
39.2pi cubic cm
82.32pi cubic cm
282.24pi cubic cm

Answers

The answer is C.

Here is the formula for volume of cone:

[tex]\frac{1}{3} \pi r^{2} h[/tex]

where r is the radius and h is the height.

[tex]\pi r^{2}[/tex] is the area of the "base" or the fomula for calculating the area of a circle.

In your question, the height is given, but you don't know the radius. However, it could be found using the circumference of 8.4pi cm.

The formula for the relationship between circumference, diameter, and the constant pi:

[tex]C =\pi d[/tex]

where C is the circumference and d is the diameter of the circle.

Substitute the numbers in:

[tex]8.4 \pi = \pi d[/tex]

Remove [tex]\pi[/tex] from both sides of the equation:

[tex]d=8.4[/tex]

Diameter is the length across the circle, while radius is half of diameter.

Hence, [tex]r =4.2[/tex]

Now that you have all the "information" you need to calculate the cone's volume, substitute the numbers into the formula:

[tex]\frac{1}{3} \pi * 4.2^{2}* 14[/tex]

You should get  [tex]82.32\pi cm^{2}[/tex]  as your answer. The [tex]\pi[/tex] is left alone because the question stated "in terms of pi", but if that weren't stated pi should be replaced with 22/7 or 3.14 depending on the question.

I hope this clears up any confusion you might have! If not, feel free to leave a comment with your question.

A furniture store offers free setup and delivery services to all points within a 25-mile radius of its warehouse distribution center. If you live 20 miles east and 14 miles south of the warehouse, will you incur a delivery charge? JUSTIFY YOUR ANSWER!

Answers

Answer:

Step-by-step explanation:

make a good drawing and notice the right triangle with legs 20 mi and 14 mi

the distance from home to the warehouse is the hypotenuse c of the right triangle thus we will use the Pythagorean Theorem:

c^2 = 20^2 + 14^2

c^2 = 596

c = 24.41 mi approximately is the distance from home to a warehouse

since 24.41 < 25 you will incur a delivery charge.

no, delivery charges will not be incurred
