Is 2115 divisible by 9 if so explain why or why not

Answers

Yes It is because when you divide any number by another and it does not have a decimal it is divisible by that number and when you divide 2115 by 9 it comes out 235 (without a decimal) so it is divisible.
Hope that makes sense lol

An angle is bisected by a segment forming two new angles <1 and <2. find m

Answers

Answer:

m∠WUV = 24°

Explanation:

An angle bisector is a line that divides an angle into two equal parts

We are given that:

UP is an angle bisector forming angles 1 and 2

This means that:

m∠1 = m∠2

We are given that:

m∠2 = 12°

Therefore:

m∠1 = m∠2 = 12°

Now, we want to get m∠WUV:

∠WUV can be written as the summation of angles 1 and 2

m∠WUV = m∠1 + m∠2

m∠WUV = 12° + 12°

m∠WUV = 24°

Hope this helps :)

Z-y+xz use x =2, y = -1, z = -3

Answers

Simple...

z-y+xz

x=2

y=-1

z=-3

Plug it in!

-3-(-1)+(2)(-3)

-3+1-6

-2-6

-8

Thus, your answer, -8.

z - y + x * z = ?
-3 - -1 + 2 * -3 =
-2 + -6 = -8

What is the percent of 5/9

Answers

To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we wanted to write $(5)/(9)$ as a percent, we need to find a fraction equivalent to $(5)/(9)$ with a 100 in the denominator of the fraction. We can do this by setting up a proportion.

$(5)/(9)$ = $(n)/(100)$

Now, we can use cross products to find the missing value.

9n = 500

÷9 ÷9

n = 55.6

Therefore, 5/9 can be written as 55.6%.

There are 55.56% of the percent of 5/9.

Since, A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

We have to given that;

To find the percent of 5/9.

Let us assume that,

the percent of 5/9 is, x

Hence, We can formulate;

⇒ 5/9 = x%

⇒ 5/9 = x / 100

⇒ x = 500/9

⇒ x = 55.56%

Thus, There are 55.56% of the percent of 5/9.
