Answer:

$21.11

Step-by-step explanation:

Initial $15.00

After 1 year, $15.00 * (1 + 5%) = $15.00 * 1.05

After 2 years, $15.00 * 1.05 * (1 + 5%) = $15.00 * 1.05²

After 7 days: $15.00 * 1.05⁷ = $21.11

Answer:

$14 in shipping and handling

Step-by-step explanation:

20 percent as a decimal is .2, so multiply 70 by .2 to determine what twenty percent of 70 is. You should get 14, which is how much shipping and handling she will pay.

Answer:

The answer is y=(-2x)-5

Answer: I think its B but it could be A i dont know

Answer:

27.53%

Step-by-step explanation:

Initial number = 100

9% increase

100*1.09= 109

17% increase

109*1.17= 127.53

The difference with the initial number is:

127.53 - 100 = 27.53

27.53/100*100% = 27.53%

This is the single percentage change

Answer:

No solution

Step-by-step explanation:

Let's solve your system by substitution.

y=3x+4;y+6=3x

Step: Solvey=3x+4for y:

y=3x+4

Step: Substitute3x+4foryiny+6=3x:

y+6=3x

3x+4+6=3x

3x+10=3x(Simplify both sides of the equation)

3x+10+−3x=3x+−3x(Add -3x to both sides)

10=0

10+−10=0+−10(Add -10 to both sides)

0=−10

Answer:

No solutions.

Answer:

exact form: 63/2

decimal form: 31.5

mixed number form: 31 1/2

Answer:

x = 8

Step-by-step explanation:

In equilateral, the length of the sides are equal.

12x - 22 = 10x - 6

Add 22 to both the sides

12x  = 10x - 6 + 22

12x = 10x + 16

Subtract '10x' from  both sides,

12x -10x = 16

2x = 16

Divide both sides by 2

x = 16/2

x = 8

Answer:

x= 8

Step-by-step explanation:
Angles ∠LPJ and ∠MPK are equal to each other

So ∠LPJ = [tex](3x+12)[/tex]

We can add angles ∠LPJ and angle ∠JPQ for a total of 90 degrees

Now with the below equation set up, you can solve for X.

[tex](3x+12)+(9x-18)=90[/tex]
[tex]12x -6 = 90[/tex]
[tex]12x = 96[/tex]
[tex]x=8[/tex]

Rewrite them all as a decimal to compare them:

0.15

1/10 = 0.10

12% = 0.12

1/20 = 0.20

Now write them in order :  1/10, 12%, 0.15, 1/20

Answer:

Step-by-step explanation:

Answer:

x < 8

*View attached image for the inequality on a number line*

Step-by-step explanation:

22 - x > 14

-22     - 22

-x > -8

/-1     /-1

x < 8

Answer:

-53

Step-by-step explanation:

I assume your question is asking for x = -5 when (f.g).

Simply plug in the equation g(x) into the variable x of the f(x) function.

[tex](fog) = -2(-4x+3)-7[/tex]

Plug in x = -5 and the answer will be -53.

Answer:

abd = ace? there is not enough context maybe you are missing an image that we need but this is the only feasible way I can use abd and ace are similar

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

They are similar shapes, using the scale factor

60/12 = 5

Using the scale factor, divide it by the area of the big shape

1200/5 = 240

The answer is C (240)

Answer:

d

Step-by-step explanation:

Answer:

-1 2/3 - (-1/3) = -4/3

Step-by-step explanation:

the first thing to note is that when you subtract a negative it is essentially adding

so your question is essential asking

write a statement involving one negative number or fraction added to another number or fraction

but you must write it like this

a - (-b) = -4/3

-5/3 - (-1/3) is essentially just -5/3 + 1/3

you can also write -5/3 as -1 2/3

this gives you -4/3

this is one of the many possible answers

Step-by-step explanation:

If the question is like this,

[tex] \tan( \frac{\pi}{3}x - 3 ) = 0[/tex]

We take the arc tan of both sides.

[tex] \tan( - 1) ( \tan( \frac{\pi}{3}x - 3 ) = \tan {}^{ - 1} ( {}^{ }0 ) [/tex]

[tex] \frac{\pi}{3} x - 3 = 0[/tex]

[tex] \frac{\pi}{3} x = 3[/tex]

[tex] = \frac{9}{\pi} [/tex]

Since the period of a tan function, is pi, we divide pi by pi/3 since pi/3is the coeffeicent of the x variable

[tex] \frac{\pi}{ \frac{\pi}{3} } = 3[/tex]

So the answer is

[tex] \frac{9}{\pi} + 3n[/tex]

If this the question,

[tex] \tan( \frac{\pi}{3} x) = 3[/tex]

[tex] \frac{\pi}{3} x = 1.249[/tex]

[tex]x = \frac{3.747}{\pi} [/tex]

The period is once again 3 so we have

[tex] \frac{3.747}{\pi} + 3n[/tex]

where n is a interger.

Equation in slope intercept form

Slope:-m=5

Y intercept=b=50

The y-intercept of the function is (0, 50) and the slope of the function is 5

Slope is defined as the rate of change of function. Given the following parameters

Fixed price = $50

If the streaming services pay $ 5.00 per unit, then the rate of change is $5

The required profit for the total number of streams is given as:

P(x) = 50 + 5x

1) The y-intercept is the point where the value of x is zero

P(x) = 50 + 5x

P(0) = 50 + 5(0)

P(0) = 50

Hence the y-intercept of the function is (0, 50)

For the slope

mx = 5x

m = 5

Hence the slope of the function is 5

ANSWER 33°

im hoping this helps i looked it up and this is what i got

Answer:

180

Step-by-step explanation:

To find the area of the rectangle, multiply 15 by 9

15 x 9 = 135
To find the area of the triangle, multiply 15 by 6, then divide by 2
15 x 6 = 90
90/2 = 45
Now add these two numbers to get the total area.
135 + 45 = 180
Hope this helps :)
