Answer:B or 540 cubic inches.

Step-by-step explanation:

So, if we multiplied all 3 values using the volume formula, we get 600 cubic inches. And if it says 90%, we multiply .9x600 and get 540 cubic inches.

Answer:

B. 540 cubic inches

Step-by-step explanation:

Let's start with the formula.

[tex]Volume=Length*Width*Height[/tex]

Or:

[tex]V=L*W*H[/tex]

We are given the Length, Width, and Height.

So we just multiply it out:

[tex]12.5*6*8=600[/tex]

The volume is 600 cubic inches

But we aren't done yet:

We now have to find 90% of 60, and we can do that in two ways

Set up a percent proportion:

[tex]\frac{x}{90}=\frac{600}{100}[/tex]

[tex]x=\frac{90*600}{100}[/tex]

[tex]x=540[/tex]

Or we could use benchmark fractions.

To find 90% of 600, we do 600 - (10% of 600)

This is just 600 - 60

540

Answer:

the first one is independent

the second one is dependent

Step-by-step explanation:

Answer:

The number of dollar bills, d, is the independents variable.

The number of quarters, q, is the depenedent variable.

Step-by-step explanation:

The number of quarters depend on the amont of dollar bills, so the quarters are the depenent variable.

Answer/Explanation:

To find out the volume of this Rectangular Prism you have to multiply by length * width * height.

So what's [tex]3\frac{3}{8} *2?[/tex] It's [tex]\frac{27}{4}[/tex], and since there are [tex]2[/tex] sides of the same length * width * height, so [tex]\frac{27}{4} *2=\frac{27}{2}[/tex].

So now the upper and bottom face of the Rectangular Prism are figured out.

Now we have to do [tex]2*2[/tex], so what's [tex]2*2?[/tex] It's [tex]4[/tex]. Now like before there are [tex]2[/tex] sides of the same length * width * height, so we do [tex]4*2[/tex], and what's [tex]4*2?[/tex] It's [tex]8[/tex], now we add them together which is [tex]\frac{27}{2} +8=\frac{43}{2}[/tex], or we can say the answer is [tex]21.5[/tex] in decimal form.

So the Volume = [tex]21.5[/tex] or [tex]\frac{43}{2}[/tex]

Wait it's actually [tex]\frac{27}{4} *4[/tex] which is [tex]27[/tex], so then we actually do [tex]27+8[/tex], which is [tex]35[/tex].

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.

Lisa earns more money because John makes $16 while Lisa makes $18.

Answer:

Step-by-step explanation:

Since this is a test, I'll give a hint:

To find a missing side, you would ussualy use the pythagoream theory, which is not only a pain to write, but pretty easy!

The formula is a^2+b^2=c^2

a and b are the "legs" (the shorter sides) and c is the hypotonus(the longest side).

In this case a=x, and b=6. C=10.

Just input a, b, and c into the equation, and if you have a fairly basic grasph on pre-algebra, then you should be able to solve this.

Hope this helps!

Answer:

8

Step-by-step explanation:

Hi!

So there are two ways to do this, the second way is the easier way

First way:

We can use the Pythagorean Theorem.

If [tex]a^{2}+ b^{2}=c^{2}[/tex]

That means:

[tex]a^{2} = c^{2} - b^{2}[/tex]

Now we plug in the numbers

[tex]x^{2} = 10^{2} - 6^{2}[/tex]

[tex]x^{2} = 100 - 36[/tex]

[tex]x^{2} = 64[/tex]

[tex]x=\sqrt{64}[/tex]

[tex]x=8[/tex]

Second way:

We can use Pythagorean Triplets

We can use the 3,4,5 triplet

We can also put this in a ratio to help you visualize this

3y:4y:5y

Over here, you'll notice that if you make y = 2, then you get this

3(2):4(2):5(2)

Simplify

6:8:10

Well, 6 and 10 are given in this problem so that means that x has to be 8

Answers:

21.75

1.37

15

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
