Divide the percent with the original price to get your answer

Answer:

60

Step-by-step explanation:

because it is parallel then ,you can use alternate angles to look for answer.

with alternate angles you know that the other side of the h angles is 120°

so you should take 180°(a straight line fixed angle) -120° and get 60°.

Answer:

A. ok so lets make a alebra equation

2.75d+6.26

first of all they charge a certain amount per mile so thats why we multiply that by the number on miles then we add the base price of 6.26

B. ok so lets just plug in

77.76

Hope This Helps!!!

(a)

Given the info that Tito charges a $6.26 fee for a ride plus $2.75 for every ride, we derive

Y is the amount of money in total

X is the amount of miles for each ride

Algebraic Expression: Y=2.75X+6.26

(b)

Plugging in 23, we get

Y=2.75(230+6.26

Y=69.51

Answer Sentence: It would take $69.51 to travel 23 miles on TIto's taxi.

Answer:

[tex]\frac{x-2}{3(x-3)}[/tex]

Step-by-step explanation:

The area of the shaded rectangle is [tex]A_1=\frac{x-2}{3}\times\frac{x+1}{4}[/tex]

The area of the large rectangle is [tex]A_2=\frac{x-3}{2}\times\frac{x+1}{2}=\frac{(x-3)(x+1)}{4}[/tex]

So the fraction is [tex]\frac{A_1}{A_2}=A_1\times\frac{1}{A_2}=\frac{x-2}{3}\times\frac{x+1}{4}\times\frac{4}{(x-3)(x+1)}=\frac{x-2}{3(x-3)}[/tex]

Answer:

x <16/3

Step-by-step explanation:

7x - 4< 4(x+3)

Distribute

7x - 4< 4x+12

Subtract 4x from each side

7x-4x - 4< 4x-4x+12

3x-4 < 12

Add4 to each side

3x-4+4 < 12+4

3x<16

Divide each side by 3

3x/3 <16/3

x <16/3

The time it will take the ball to reach a height of 90feet is 1.2 and 4.4secs

Given the height h (in feet) of the ball t seconds after being kicked expressed as:

h = –16t2 + 90t + 4.

If the ball is at a height of 90feet, hence:

90 = –16t2 + 90t + 4

–16t2 + 90t + 4 - 90 = 0

16t^2  -90t  + 86= 0

8t^2  -45t  + 43= 0

Factorizing the result to get the values of t:

[tex]t=\frac{45 \pm \sqrt{45^2-4(43)(8)} }{16} \\t=\frac{45 \pm \sqrt{2,025-1376} }{16} \\t=\frac{45 \pm {25.47}}{16} \\t=4.4s \ and\ 1.22secs[/tex]

Hence the time it will take the ball to reach a height of 90feet is 1.2 and 4.4secs

Answer:

D. d ≈ 9.4

Step-by-step explanation:

[] We can use the distance formula to solve

-> The distance formal is attached.

[tex]d = \sqrt{(4-9)^{2}+ (2-10)^{2} }[/tex]

[tex]d = \sqrt{(-5)^{2}+ (-8)^{2} }[/tex]

[tex]d = \sqrt{25+ 64 }[/tex]

[tex]d = \sqrt{89}[/tex]

d ≈ 9.4

Answer:

It's D. I did the test and got it right.

Answer:

23 degrees

To get this:

5x means 5 squared, also known as 5 times itself. 5x5 is 25.

25 - 2 is 23.

23 degrees should be it.

Answer:

The value of x is 16 degree

Step-by-step explanation:

5x-2=78(vertically opposite angle)

or,5x=78+2

or,x=80/5

Using the slope concept, it is found that he stepped back 63.44 feet.

The slope is given by the vertical change divided by the horizontal change.

It's also the tangent of the angle of depression.

Initially, we have that:

Hence:

[tex]\tan{68^{\circ}} = \frac{85}{d}[/tex]

[tex]d = \frac{85}{\tan{68^{\circ}}}[/tex]

[tex]d = 34.34[/tex]

When he stepped back, the angle was of 41º, hence:

[tex]\tan{41^{\circ}} = \frac{85}{d}[/tex]

[tex]d = \frac{85}{\tan{41^{\circ}}}[/tex]

[tex]d = 97.78[/tex]

97.78 - 34.34 = 63.44.

Hence he stepped back 63.44 feet.

Answer:

39.2 m/s

Step-by-step explanation:

Let a = 9.8 m/s^2, t = 8 sec, find the initial velocity v

After time t, the rock hit the ground, so the height h = 0

Use h = vt - at^2/2 = 0

v = at/2 = 9.8 * 8/2 = 39.2 m/s

Answer:

a) f(-8) = 1

b) f(-4) = 5

c) f(2) is undefined

Step-by-step explanation:

f(x) notation means "the function of x".  Therefore, for f(-8) you need to find the y value when x = -8.  Locate -8 on the x-axis and then follow up (or down) until you meet the curve/line.  Then find the corresponding y-coordinate of this point.

From inspection of the graph:

a) f(-8) = 1

b) f(-4) = 5

c) f(2) is undefined

Answer:

Assuming that all other factors are equal, (and they never are), I would prefer a 20% or more ROI investment, located in a tax deferred, or tax exempt account!

Assuming that you are for some reason entirely unmotivated to look for better investments than the two you have pointed out, why not just buy the 8.1% investment with your IRA, Roth IRA, 401(k), SEP IRA, or spousal IRA funds?

You can then pretty much ignore your tax rate. Just move over any portion of your standard deduction that remains unused near the end of the year, via a Roth conversion. You will pay no additional taxes, and the money converted will forever remain free of RMDs, (which will otherwise occur later on), for the rest of your life!

Step-by-step explanation:

Use your now freed up taxable money to invest in tax free transactions, (similar to the effect of having a periodic Roth IRA), and live happily ever after!
