What is the distance between two points(0,0)(-3,5)

Answers

Step-by-step explanation:

Think of it like a right triangle. Do you have a graph handy?

Ok, graph both of the points. Now connect the points. That's our hypotenuse and the side length we want to find.

Now, bring down a line from (-3,5) to the x axis. Do you see a right triangle?

All we have to do is find the hypotenuse of this right triangle we just drew. We already have the leg lengths which are 3 and 5. Using this, do the pythagorean theorem.

9+25=34

√34 is our hypotenuse & distance between the points

Thenks and mark me brainliest :))

Answer:

The probability that the third student will draw a green is 19%.

Step-by-step explanation:

Definition of Probability Probability means possibility of occurrence. It is a branch of mathematics which deals with the occurrence of particular event out of some random events.

Given marbles 10 red, 10 blue, 8 green, 8 purple, and 8 yellow marbles .

Therefore total marbles will be 44.

Since the first student in the room draws a yellow, and the second draws a blue ,thus remaining marbles will be 42.

So, the probability that the third student will draw a green is [tex]\frac{8}{42}[/tex]×[tex]100\\[/tex] = 19%

PLS HELLPP

Answers

Answer:

maybe 6 1/2

Step-by-step explanation:

5 square inches is the area of triangle PQR in square inches.

What is Triangle?

A triangle is a three-sided polygon that consists of three edges and three vertices.

Given a triangle PQR.

We need to find the measurement is closest to the area of triangle PQR in square inches.

The PR is 2.6 inches in height and RQ is 4.1 inches.

We know that area of triangle is 1/2 times base and height.

By using ruler we calculated the height of triangle is 2.6 inches and base is 4.1 inches

The formula for area is

Area=1/2(Base×Height)

Plug in the values of base and height

=1/2(4.1×2.6)

=1/2(10.66)

=5.33

=5 square inches

Hence, 5 square inches is the area of triangle PQR in square inches.

Answer:

set them equal to eachother, i gotta look at my notes tho

Step-by-step explanation:

I think it's like this

3x-26=2x+24

We simpilfy the equation to the form which is simple to understand.

3x-26=2x+24

We move allterms containing X to the left and all others terms to the right

+3x-2x=+24+26

We simplfiy left and right sideof the eqution.

+1x=+50

We divide both sides of the equation by 1 to get x.

Find the 8th term 50,20,8

Answers

Answer:

Step-by-step explanation:

Answer:

0.08192

Step-by-step explanation:

Given 50, 20, 8, ...

The sequence is geometric in nature

The nth term of the geometric sequence is exoressed as;

Tn = ar^{n-1}

a is the first term = 50

r is the common ratio = 20/50 = 8/20 = 2/5

n is the number of term = 8 (since we need the 8th term)

Substitute

T8 = 50(2/5)^{8-1}

T8 = 50(2/5)^7

T8 = 50(128/78,125)

T8 = 0.08192

Hence the 8th term is 0.08192.
