If we were getting 60% discount early and then again we are receiving 20% discount for using credit card then it means that we are getting 80% discount.

Discount means the amount which is deducted by sellers from the amount to be payable by buyers.

Let the total price to be paid by us to store is $100.

Discount received because on purchase on sale day=100*60%

=60

Discount received due to use of credit card=100*20%

=20

Total discount received from store=60+20

=80

Percentage=80/100*100

=80%

Hence the total discount received by us from store is 80%.

Answer:

Step-by-step explanation:

Beth's position over time is constant, which makes the problem a lot easier. You are asked for the rate of position versus time, so begin by doing that. Since the rate is constant, clearly from the table, you can take any two data points and take their ratio. Her rate would be 11 feet every 5 seconds, or equivalently 2.2 feet every second. To graph the data, put position on the x-axis and time on the y-axis. The slope will be 2.2 at every point along her bike ride.

Moving on to the third part. If Amy traveled at a rate of 75 feet every 30 seconds, then she would be traveling 2.5 feet every second. Amy's rate is larger than Beth's rate. Since the rate corresponds to the slope of the postion vs. time graph, Amy's graph will have a steeper incline since the slope is 2.5

One way we can organize a linear equation is in standard form:

[tex]Ax+By=C[/tex]

Another way we can organize a linear equation is in point-slope form:

[tex]y-y_1=m(x-x_1)[/tex]

We're given:

We only need the point-slope form equation to find the stand form of the equation for this line. All we have to do is rearrange the numbers to get them in the right places.

[tex]y+7=-\dfrac{5}{2}(x-10)[/tex]

⇒ First, multiply both sides by 2 to get rid of the fraction:

[tex]2y+14=-5(x-10)[/tex]

⇒ Now, open up the parentheses:

[tex]2y+14=-5x+50[/tex]

⇒ Move -5x to the other side:

[tex]5x+2y+14=50[/tex]

⇒ Move 14 to the other side:

[tex]5x+2y=50-14[/tex]

⇒ Combine like terms:

[tex]5x+2y=36[/tex]

[tex]5x+2y=36[/tex]

Hi!

Your answer is [tex]5x^2-7x-8[/tex].

We are asked:

[tex](-3x^2-5x+1)+(8x^2-2x-9)[/tex]

As we are adding them, we can remove the parenthesis.

[tex]-3x^2-5x+1+8x^2-2x-9[/tex]

Now, we can switch the order of the terms around to cause like terms to be by each other:

[tex]-3x^2+8x^2-5x-2x+1-9[/tex]

Finally, add like terms:

[tex]5x^2-7x-8[/tex]

5x² -7x -8 is the result of adding the polynomials -3x²-5x +1 and 8x²-2x-9. The result obtained by combining the like terms.

The two polynomials are  -3x²-5x +1 and 8x²-2x-9.

To add the two polynomials, you simply combine like terms.

Like terms are terms that have the same variable raised to the same power.

In this case, the variables are x² and x.

Let's add the given polynomials:

= -3x²-5x +1 + 8x²-2x-9

Group the like terms:

= -3x²+ 8x²-5x-2x+1-9

Combine like terms:

= 5x² -7x -8

Hence, 5x² -7x -8 is the result of adding -3x²-5x +1 and 8x²-2x-9.

The expression that represents the volume of the composite figure is 16/3πr³ + r³

The given parameters are:

The volume of a cube is:

V = l³

So, we have:

V = r³

The volume of a hemisphere is:

V = (2/3)πr³

So, we have:

V = (2/3)π(2r)³

Evaluate

V = (2/3)π * 8r³

This gives

V = 16/3πr³

Add both volumes

Volume = 16/3πr³ + r³

Hence, the expression that represents the volume of the figure is 16/3πr³ + r³

Step-by-step explanation:

Remark

The base of the figure is a pentagon

The area of the base of a pentagon is

A=(1/4) * √[5(5+2√5)] * s2

The Formula for the Volume of a "pyramid" of this nature is

Volume = Base * h / 3

Givens

h = 10 feet

s = 8 feet

Base = formula in the remark section

Solution.

Find the base first.

A=(1/4) * √[5(5+2√ 5)] * s2     Find the value of 5 + 2√5

Area = 0.25√[5*(9.47)] * s^2 Find what is under the root sign

Area = 0.25√47.36   * s^2     Take the square root of 47.36. use s = 8

Area = 0.25 * 6.88 * 8^2         Combine.

Area = 110.11

Now find the volume

V = B * h/3

V = 110.11 * 10 / 3

V = 367.04     cubic feet.

Answer:

Step-by-step explanation:

since you have 84/42, and you are supposed to convert the improper fraction to a mixed number, the easiest place to start is to divide the two numbers and find the remainder. In this case, however, there is no remainder, as 84 divided by 42 is exactly 2. Therefore, the most simplified fraction would be 2 (although it does not look like a fraction the most simplified form of the fraction is 2/1 --> which is just 2). Hope this helps!

Step-by-step explanation:

First we need to get his speed:

speed = distance / time

If he travelled 24 miles in 20 mintues, his speed is 24 / 20 = 1.2 miles per minute

If he travelled 18 miles in 15 minutes, his speed is 18 / 15 = 1.2 miles per minute

Those two should give us the same answer since it says that the distance varies linear with time, which means that his speed is constant.

Then after 30 minutes he will have traveled: 1.2 x 30 = 36 miles

Answer:

Your answer is C, 14ft

Step-by-step explanation:

Your Given Measurements (in feet):

Height = 5 1/2 ; Width = 1 1/2

___________________________________________________

The Perimeter Formula:

L + W + L + W = P

In this case, the "L" which is length going to get substituted as Height.

5 1/2 is 5.5 because if you do 1/2 on the calculator, you get 0.5 which you can add 5 to get 5.5.

1 1/2 is 1.5 which is the same as the 5 1/2.

____________________________________________________

Now do 5.5 + 1.5 + 5.5 + 1.5 = perimeter

5.5 + 1.5 = 7

7 + 7 = 14ft

Your answer is C: 14 ft
