What percentage
of total hours was
spent jogging?

if you find the total hours for each sport i’ll give u brainlistttt paleeease

Answers

Answer:

40%

Step-by-step explanation:

So I mostly will focus on the jogging total hours because thats literally what it says lol. Anyways, here I used the percent equation, which is

___ is ___% of ___. Since the question is "what percent", we mark our blank percent part as x, and when I fill the equation in it will seem like this:

"20 is x% of 50 (total hours)". So, now I translate, and this means:

20=x50, or in other words, 20=50x. To get x alone we divide by 50, but we also do it for the 20. 20/50 is .4, but because it has to be a percent, we move the decimal 2 places to the right, which gives 40, and finally it becomes

40%.

Hope it helps

Answer:

40%

Step-by-step explanation:

(20 hours Jogging)/(50 hours Total) = 0.4

0.4 * 100 = 40

The expression |-2-(-3) can be used to find the difference between point A and which other point?

A. Point B
B. Point C
C. Point D
D. Point E

Answers

Answer:

C. Point D

Step-by-step explanation:

Distance between two points

Given two points A(x,y) and B(w,z), the distance between them is:

[tex]d=\sqrt{(z-y)^2+(w-x)^2}[/tex]

If both points have the same y-coordinate (y=z), then

[tex]d = |w - x|[/tex]

Point A has coordinates (-2,3). Point D has coordinates (-3,3). The distance between them is

[tex]d = | -2 - (-3) |[/tex]

Thus the correct choice is

C. Point D

Answer:

y = -5/2x +4

Step-by-step explanation:

First, make the equation into standard form.

5x + 2y = -10

2y = -5x - 10

y = -2.5x - 5

In order for two lines to be parallel, they must have the same slope. (In y = mx + b, "m" is the slope)

The slope in y = -2.5x - 5 is -2.5, so we need to find an equation with a slope of -2.5 (or -5/2)

In y = -2/5x - 8, the slope is -2/5

In y = 2/5x + 7, the slope is 2/5

In y = 5/2x - 6, the slope is 5/2

In y = -5/2x +4, the slope is -5/2.  

Thus, y = -5/2x +4 is the right answer
