Answer:

$5.40

Step-by-step explanation:

First, find Dave's purchase. To do this, you multiply 15 by the tax percent and add that to the original.

So:

15 x 8% = 15 x 0.08 = 1.2

15 + 1.2 = 16.2

Next, do the same for Mel's purchase:

20 x 8% = 20 x 0.08 = 1.6

20 + 1.6 = 21.6

Then, you subtract Dave's purchase from Mel's:

21.6 - 16.2 = 5.4

This comes out to $5.40

Answer:

50°

Step-by-step explanation:

90-40= 50° ............

Answer:

To figure out the change, we subtract the original temperature by the following after temperature.

18°F - original

-9°F - subsequent time after original

So we set up the equation;

18°F - (-9°F)

(Two negatives combine to form a positive)

18°F + 9°F

= 27°F was the change in temperature.

The change in temperature from 2:00 PM to 10:00 PM is -27° F.

Temperature is a physical quantity that measures the coldness or hotness of an object in reference to some standard value.

Change in temperature can be defined by the difference of the final temperature with that of the initial temperature.

Temperature is usually measured in degree Celsius or degree Fahreheit.

Temperature at 2:00 PM = 18° F

Temperature at 10:00 PM = -9° F

Change in temperature = Final temperature - Initial temperature

                                       =  -9° F - 18° F

                                       = -27° F

Hence, the change in temperature can be calculated as -27° F.

The function (fg)(x) is a composite function

The value of the function (fg)(x) is 2x^3 + 7x^2 - 19x - 20

The functions are given as:

f(x) = 2x^2 - 3x - 4 and g(x) = x + 5.

To calculate (fg)(x), we make use of

(fg)(x) = f(x) * g(x)

So, we  have:

(fg)(x) = (2x^2 - 3x - 4) * (x + 5)

Expand

(fg)(x) = 2x^3 - 3x^2 - 4x + 10x^2 - 15x - 20

Collect like terms

(fg)(x) = 2x^3 - 3x^2 + 10x^2 - 4x - 15x - 20

Evaluate

(fg)(x) = 2x^3 + 7x^2 - 19x - 20

Hence, the function (fg)(x) is 2x^3 + 7x^2 - 19x - 20

Answer:

length= 1115 inches

width= 545 inches

Step-by-step explanation:

The perimeter of the rectangular rug is the sum of the lengths of all its sides.

Start by defining the variables that we are going to use throughout our working.

Let the length and the width of the rug be L and W inches respectively.

Perimeter= 2(L +W)

Given that the length is 25 inches more than twice the width,

L= 2W +25 -----(1)

3320= 2(2W +25 +W)

Divide both sides by 2:

1660= 2W +W +25

1660= 3W +25

3W= 1660 -25

3W= 1635

Divide both sides by 3:

W= 1635 ÷3

W= 545

Substitute W= 545 into (1):

L= 2(545) +25

L= 1115

Thus, the length and width of the rug is 1115 and 545 inches respectively.

Answer:

[tex]\displaystyle \large{x=\pm \sqrt{y}}[/tex]

Step-by-step explanation:

We are given the equation:

[tex]\displaystyle \large{y=x^2}[/tex]

Make ‘x’ the subject of the formula by square root both sides:

[tex]\displaystyle \large{\sqrt{y}=\sqrt{x^2}}[/tex]

Cancel the square root and square in RHS and write plus-minus in LHS:

[tex]\displaystyle \large{\pm \sqrt{y}= x}\\\displaystyle \large{x=\pm \sqrt{y}}[/tex]

Therefore, the solution is [tex]\displaystyle \large{x=\pm \sqrt{y}}[/tex]

__________________________________________________________

Summary

To make a variable as the subject of equation means to isolate that variable. For an example, if you want to make y as the subject, you’ll have to isolate y-term.

You may also be curious why do you have to add plus-minus on another side when cancelling [tex]\displaystyle \large{\sqrt{x^2}}[/tex] because [tex]\displaystyle \large{\sqrt{x^2}=|x|}[/tex] and [tex]\displaystyle \large{|x|}[/tex] for their positive and their counterparts (opposite/negative) will always give same y-value.

From an example:

[tex]\displaystyle \large{\sqrt{x^2}=4}[/tex] can be rewritten as [tex]\displaystyle \large{|x|=4}[/tex], cancel absolute sign/square root then write plus-minus which the solution is [tex]\displaystyle \large{x=\pm 4}[/tex] and if you substitute x = 4 or -4, the equation will be true for both values.

Answer:

4 and - 2

Step-by-step explanation:

x² - 2x = 8

x² - 2x - 8 = 0

x² + 2x - 4x - 8 = 0

x ( x + 2 ) - 4 ( x + 2 ) = 0

( x + 2 ) ( x - 4 ) = 0

x + 2 = 0

x = - 2

x - 4 = 0

x = 4

The values of x are - 2 and 4.

Jonathan will need a warping paper of 420.78m^2

Data;

To find the amount of warping paper used, we can use the formula of surface area of an equilateral triangle since the triangle used here is an equilateral triangle.

[tex]Surface Area = base area + \frac{1}{2}(perimeter * slant height)[/tex]

Let's calculate the base area and perimeter of the triangle.

base area of an equilateral triangle is given as

[tex]B.A = \frac{\sqrt{3} }{4} a^2[/tex]

Let's substitute the value and solve

[tex]B.A = \frac{\sqrt{3} }{4} a^2\\B.A = \frac{\sqrt{3} }{4}*10.39^2\\B.A = 46.74m^2[/tex]

The base area is 46.74m^2

Let's calculate the perimeter of the triangle

[tex]P = 3a\\[/tex]

Substitute the value into the equation and solve

[tex]P = 3a \\P = 3 * 10.39\\P = 31.17m^2[/tex]

We can proceed to substitute the values of the base area and perimeter of the triangle into the formula of the surface area of an equilateral triangle.

[tex]S.A = base area + \frac{1}{2}(perimeter * slant height)\\S.A = 46.74 + \frac{1}{2}(31.17*12)\\S.A = 46.74 + 374.04\\S.A = 420.78m^2[/tex]

The surface area of the equilateral triangle is 420.78m^2

Answer:c

Step-by-step explanation:

Answer:

40

Step-by-step explanation:

Angle KPJ is going to have the same measure as Angle DPE. This problem is a bit tricky, but I'll try my best to explain it. A straight angle is basically just a straight line, and it equals 180 degrees. Angle FPG is a straight angle.

To find the measure of Angle KPJ, we first have to find the measure of angle DPE, and the way we're gonna do that is add together the other angles in the straight angle (which would be Angle FPD and Angle EPG) and then subtract that from 180 (measure of a straight angle).

That might have sounded a bit confusing, but that's the best way I could explain it. Now, let's add Angle FPD and Angle EPG.

105 + 35 = 140

Now, let's subtract that from 180.

180 - 140 = 40

We now know that the measure of Angle DPE is 40, and since it's equivalent to Angle KPJ, our answer is 40!

I know that was confusing, but I hope it helped a little bit! Have a lovely day!! :)
