3 0

Answer:

300

Step-by-step explanation:

Sum the parts of the ratio : 3 + 2 = 5 parts

Divide the number of appointments by 5 to find the value of one part of the ratio, that is

$\frac{500}{5}$ = 100 ← value of 1 part of the ratio

The mums consisted of 3 parts, hence

3 × 100 = 300 ← appointments with mums

-4 + x / 2 = 3 urgent!

Zina [86]

$\frac{-4 + x}{2}$ = 3 Multiply both sides by 2
-4 + x = 6 Add 4 to both sides (to cancle out the -4)
x = 10

Whats the distance between the points (2, 7) and (2, 15)

sveta [45]

Answer:

The distance between the points (2, 7) and (2, 15) is 8.

Step-by-step explanation:

<u>What is the Distance between Two Points?</u>

For any two points there is exactly one line segment connecting them. The distance between two points is the length of the line segment connecting them. Note that the distance between two points is always positive. Segments that have equal length are called congruent segments.

How to Solve:

Formula:

$\sqrt{(x2-x1)^2+(y2-y1)^2}$

Putting Values:

$=\sqrt{(2-2)^2+(15-7)^2}$

$=\sqrt{(0)^2+(8)^2}$

$=\sqrt{0+64}$

$=\sqrt{64}$

$=8$

Here's a question for the day, it's simple but it needs explaining.

GuDViN [60]

It is used to see if a graph represents a function because if there is 2 dots or intersecting lines within the other lines then it is not a function. if there is only one line or dot, then yes, it is a function. hope i explained it well.
