The speed of a car in mph varies directly with the speed of a car in kph. The speed of 75
mph is equivalent to 120 kph. How many kph is 45 mph?

please help asap !

==================================================

Work Shown:

x = original price

y = sale price

d = discount = amount saved

d = 12% of x = 0.12x

y = x - d = x - 0.12x = 0.88x

Note how 0.88 = 88%, and this represents the percentage you have to pay if you get 12% off.

We're told the sale price is y = 44, so this leads to...

y = 0.88x

44 = 0.88x

0.88x = 44

x = 44/0.88

x = 50

The original price was $50

---------------------

Check:

If the original price was $50, then the amount you save is 0.12*50 = 6 dollars, which is the discount.

The sale price is 50-6 = 44 dollars which matches up with what your teacher gave you. The answer is confirmed.

Answer:

55

Step-by-step explanation:

This is 55 because you need to make a sum of 180 when making a line and 125+55=180

Answer:

55 degrees.

Step-by-step explanation:

If you see that it is parallel. You can see that each angle on the top and bottom of it equals 360 degrees. So if the same 360 degree angle is at the bottom of these both. And both of then have 2 180 equalling degrees on the top and bottom of it. Then that would mean for the 125 the other side would have 55 degrees equalling 180. Same for the bottom so that would mean that it would be the same for the bottom 360 degree angle making me absolutely sure that X is equal to 55 degrees.

Answer:

4) 6 students

5) 7 fewer students

6) No, you can not tell from the frequency table how many students ran a mile in exactly 12 minutes.

Step-by-step explanation:

4) you’d look at the row from 8:00-8:59.

5) Add the first two rows together (6+2=8), then subtract that by the sum of  the last two rows (9+6=15), which is 7

6) There’s no pattern in the frequency table, and the data points would be plotted differently since it’d be from a range of times, not one set time.

Hope this helped, sorry if I’m wrong on #6 ;)

The 4th girls answer was 2

The fourth girl danced with two of boys.

Two or more expressions with an Equal sign is called as Equation.

Given,

At a party there were 4 boys and 4 girls.

Boys only danced with girls and girls only danced with boys.

In boys, first boys dance with  3 girls

Second boy danced with one girl

Third boy danced with two girls

Fourth boy danced with two girls

3+1+2+2=8

When comes to four girls, three girls said they danced with two boys.

We need to find with how many boys fourth girl danced.

2+2+2+x=8

x+6=8

x=2

Hence, the fourth girl danced with two of boys.

Answer:

x=29

Step-by-step explanation:

the angles shown are supplementary meaning that they will add up to equal 180 so to solve x we setup and equation

180=4x-1+65

step 1 combine like terms

180=4x+64

step 2 subtract 64 from each side

116=4x

step 3 divide each side by 4

x=29

Answer:

The distance would be 12.31073415. Rounded, 12.31

Step-by-step explanation:

First off, we know a decagon has 10 sides. Secondly, it is given that the total side length is 8 feet- split in half it's 4 and 4 (this will come into play in the formula). Next, we want to find the angle measure of one of the isosceles triangles. Thus, do 360/10 which gives 36. Then do 36/2 which equals 18. This is the angle measure we need. Now that we have the necessary information, we can set up the formula. Following SOHCAHTOA, we can see that we need to use the tangent to find the apothem since our opposite side length of 4 is given. Set up the equation like so: tan18 = 4/a. When plugged in and solved, the answer of 12.31073415 is received.

Answer:

 \bold{\text{Slope (m)}=\dfrac{1}{4}}Slope (m)=41

Step-by-step explanation:

A linear equation is of the form: y = mx + b   where

m is the slope

b is the y-intercept (where it crosses the y-axis)

x + 4y = 16

     4y = -x + 16

       y = -\dfrac{1}{4}x+\dfrac{16}{4}y=−41x+416

       y=-\dfrac{1}{4}x+4y=−41x+4

The y-intercept (b) = 4

Next, find the slope given point (4, 5) and b = 4

\begin{gathered}y=mx+b\\\\5=m(4)+4\\\\1=4m\\\\\dfrac{1}{4}=m\\\\\\\\\large\boxed{Slope (m)=\dfrac{1}{4}}\end{gathered}y=mx+b5=m(4)+41=4m41=mSlope(m)=41

Answer:

  f(2) = 36

Step-by-step explanation:

Put 2 where x is and do the arithmetic.

  f(2) = 6^2

An exponent of 2 means 6 is a factor two times.

  f(2) = 6×6

  f(2) = 36

Answer:

36

Step-by-step explanation:

To evaluate f(x) = 6^x at x = 2, substitute 2 for x:

f(2) = 6^2 = 36

The ratio of the areas will be will be 1 : 9

Step-by-step explanation:

The linear scale factor represents a ratio that is used to multiply the dimensions of objects so that accurate geometries can be transferred between real-life and paper.

The linear scale factor is quite different from the area scale factor but related to it in the following way:

The area factor can be obtained by squaring the linear scale factor.

This is Area factor = (Linear scale factor) ^2.

Linear scale factor = (1:3)

Area factor = [tex]1^2 : 3^2[/tex]

Area factor will be 1: 9

Thus, when the linear scale factor is 1:3 the area factor will be 1 : 9

Answer:

  x = 20, or 125

Step-by-step explanation:

We cannot tell the angle x is intended to refer to. So, here are two answers. Choose the one you think applies.

__

The triangle that includes both marked angles is a right triangle. (The tangent meets the circle at right angles to the radius.) So, the angle x° at the external point is the complement of the marked central angle.

  x° = 90° -70°

  x = 20

__

If x° is referring to the exterior angle associated with the isosceles triangle within the circle, then its measure is the supplement of the interior base angle of that triangle. It is ...

  x° = 180° -(180° -70°)/2 = 90° +70°/2

  x = 125
