Where do use a sensor to measure the speed of a moving car at different times. Each time, the sensor measure the speed of the car in both miles per hour and kilometers per hour. The picture below shows her results.

Answer:

below pls make me brainliest and like.

Step-by-step explanation:

d= 2.2v+\frac{v^2}{20}. to calculate breaking distance then breaks.

[tex]~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ C(\stackrel{x_1}{1}~,~\stackrel{y_1}{0})\qquad D(\stackrel{x_2}{-7}~,~\stackrel{y_2}{2}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left(\cfrac{ -7 + 1}{2}~~~ ,~~~ \cfrac{ 2 + 0}{2} \right)\implies \left(\cfrac{-6}{2}~~,~~\cfrac{2}{2} \right)\implies (-3~~,~~1)[/tex]

Answer:

Midpoint: (-0.5, -1)

Step-by-step explanation:

Solution: M=([tex]x m[/tex],[tex]ym[/tex])/2 or ([tex]x[/tex]+[tex]x[/tex]/2, [tex]y[/tex]+[tex]y[/tex]/2)

add the first [tex]x[/tex] coordinate plus the second [tex]x[/tex] coordinate

do the same for the two [tex]y[/tex] coordinates

then divide them both by 2

should look something like this: (1+0 /2, -7+2 /2)

[tex]x[/tex]= 1+0= 1 / 2 + 0.5 or one half 1/2

[tex]y[/tex]= -7+2= -5 / 2 = -2.5 or four one half -2 1/2

BUT we are not done here, since we cant divide 1/2 no more because it will still give us the same answer (0.5) we move into the next number, -2 1/2, -2 x 1/2 = -1

So our answer is (-0.5, -1)

Step-by-step explanation:

25/5=5

30/2=15

Answer:

(4,2) and (-4,2)

Step-by-step explanation:

You can see that we have 2 points, which means we have 2 sides of the rectangle. The length of that side is 8. we know that a rectangle has 2 sets of parallel sides, and that they have 2 sets of equal sides. We now know that there are 2 sides with side lengths equaling 16, which we then subtract from 20. We get 4, which we then divide by 2 because there will be 2 more sides. We then move 2 down from both points and take the point which we get from that, which is (4,2) and (-4,2).

Answer:

4) 0.425, 17/40, 42.5%
5) 0.875, 7/8, 87.5%

Step-by-step explanation:

4) 17/40= 0.425, 17/40 is simplified to the lowest form already, and (0.425x100)x 1/100

5) 35/40=0.875, 35/40=7/8, and (0.875 * 100) * 1/100= 87.5%


i hope htis helps sorry if i got anything wrong

Samantha's percent error is 15.24%.

The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.

Given:

Samantha guessed there were 295 jelly beans.

There were actually 250 jelly beans in the jar.

So, the percent error

= (295- 250) / 295 x 100

= 45 / 295 x 100

= 0.15254 x 100

= 15.24 %

Answer: The correct answer for this question is this one: "(10-y)^2". Ociel has designed a square mural that measures 10 feet on each side. Bill has also designed a square mural, but his measures y feet shorter on each side.

Step-by-step explanation:

Area of Ociel's mural = 10 * 10 = 100 ft^2

Area of Bill's mural = (10-y)^2

Answer:

12in³

Step-by-step explanation:

V = (B * h) / 3, where B is the area of the base and h is the height.

The base is a rectangle, so it's easy to find it's area:

B = 3 * 2 = 6

Now just find the volume:

V = (6 * 6) / 3 = 36 / 3 = 12in³

Step-by-step explanation:

Answer:

The lowest common multiple of 10 and 25 is 50, so set that as the denominator.

9/10=45/50 (multiply by 5)

23/25=46/50 (multiply by 2)

46/50 > 45/50 therefore

23/25 > 9/10.
