10. (Section 4.7) John filled his gas tank and noted that the odometer read 38,320.8 miles. After the next filling, the odometer

read 38,735.5 miles. It took 14.5 gal to fill the tank. How many miles per gallon did John get?

Find the number of miles he drove by subtracting the odometer readings:

38735.5 - 38320.8 = 414.7 miles.

Now divide the number of miles driven by the number of gallons:

414.7 / 14.5 = 28.6 miles per gallon.

If instead of randomly selecting two people there were five, what is the probability that all five are right-handed
lozanna [386]

Answer:

1/32

Step-by-step explanation:

We can break this question down. If we had 1 person and they are right-handed, the probability is 1/2 because they are either left-handed or right-handed. Knowing that, we can multiply the probability of having 1 person being right-handed 5 times because there are 5 people in the question.

1/2 × 1/2 × 1/2 × 1/2 × 1/2 = 1/(2⁵) = 1/32

Therefore, the probability of randomly selecting 5 people who are right-handed is 1/32.

I hope this helps and please mark me as brainliest!

Determine whether the lines are parallel or perpendicular or neither. 2x=y−10 and y=−2x
MrRa [10]

Put the first equation in slope-intercept form, or y = mx + b. Start by subtracting y from both sides.

2x - y = -10, subtract 2x from both sides.

-y = -10 - 2x

Divide both sides by negative one.

y = 10 + 2x

To find the slope when the equations are in slope-intercept form you look at the coefficient of x. The first equation has the slope of 2 (which we just found), and the second equation has the slope of -2.

Parallel lines have the same slope and perpendicular lines have opposite reciprocal slopes. Since 2 and -2 are neither of these, your answer is neither.

Please help me. 50 point question
OverLord2011 [107]

Step-by-step explanation:

Hey there!!!!

Given,

Angle r and angle s are supplementary angle.

And angle r = 120°.

Now, we have,

supplementary angle's sum is always 180°.

So, angle r + angle s = 180°.

or, 120°+ angle s = 180°

Therefore the measure of angle s is 60°.
