Answer:

I believe your answer would be the following:

A) 250 miles in 5 hours.

C) 200 miles in 4 hours

E) 700 miles in 14 hour

Step-by-step explanation:

Unit rate = 50

A) 250 miles in 5 hours // 50*5 = 250 (CORRECT)

B) 300 miles in 5 hours // 50*5 ≠ 300 (WRONG)

C) 200 miles in 4 hours // 50*4 = 200 (CORRECT)

D) 240 miles in 4 hours // 50*4 ≠ 240 (WRONG)

E) 700 miles in 14 hours // 50*14 = 700 (CORRECT)

Hope this helps! :)

<h3>Answers: Choice A, Choice C, Choice E</h3>

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

Explanation:

We use this formula

speed = distance/time

to divide each pair of values given.

  • For choice A, we have speed = distance/time = 250/5 = 50 mph which shows choice A is one of the answers.
  • Choice B doesn't work though because 300/5 = 60 mph.
  • Choice C works since 200/4 = 50 mph.
  • Choice D doesn't work: 240/4 = 60 mph
  • But choice E does work: 700/14 = 50 mph

To summarize, we got the following speeds

  • A) 50 mph
  • B) 60 mph
  • C) 50 mph
  • D) 60 mph
  • E) 50 mph

Who knows how to do this Bc I don’t understand
Fynjy0 [20]

Answer:

WV should be equal to XY

Step-by-step explanation:

since it is the HL postulate meaning hypotenuse and leg, we need to show that the hypotenuses of both triangles are equal since we are already given that one of their legs are congruent. we are also given that they are right triangles.

(2, 7) and (-6, -2) find the distance between each pair of points
yaroslaw [1]

Answer:

\sqrt{145}

Step-by-step explanation:

Hi there!

We are given the points (2, 7) and (-6, -2). We want to find the distance between them. To do that, we can use the distance formula

The distance formula is given as \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}, where (x_1, y_1) and (x_2, y_2) are points

We have 2 points, which is what we need to find the distance, but let's label their values to avoid any confusion

x_1=2\\y_1=7\\x_2=-6\\y_2=-2

Now substitute those values into the formula:

\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

\sqrt{(-6-2)^2+(-2-7)^2}

Simplify the values under the radical:

\sqrt{(-8)^2+(-9)^2}

Raise to the second power:

\sqrt{64+81}

Add the numbers under the radical together

\sqrt{145}

The answer can be left as that, as the radical cannot be simplified.

Hope this helps!

Write 3x+4y=12 in slope intercept form
cestrela7 [59]
Ok, let’s take it step by step.
In order to write an equation in slope intercept form, solve for y.
3x+4y=12
First, subtract 3x from both sides.
4y=-3x+12
Now, divide both sides by 4.
y=-3/4x+3.

So, 3x+4y=12 written in slope intercept form is y=-3/4x+3.
