87

You can add up the angles that are labeled(73,110,and 90 because of the right angle) and get 273.

For a quadrilateral, all of the angles add up to 360.

So, subtract 360-273.

You get 87.

Hope this helps:)

How do you write 22.5% as a fraction in simplest form?

Darya [45]

Answer: 9/40

Step-by-step explanation: To write a percent as a fraction in lowest terms, remember that a percent is a ratio that compares a number to 100.

So here, 22.5% can be written as the ratio 22.5 to 100 or 22.5/100.

Notice however that 22.5/100 is not in lowest terms so we need to multiply the numerator and the denominator of 22.5 by 10 in order to remove the decimal point. When we do this, we will end up with the fraction 225/1000.

The fraction 225/1000 can be written in lowest terms by dividing both the numerator and the denominator by 25 and we get the fraction 9/40.

Therefore, 22.5% can be written as the fraction 9/40.

Question 7 not answered which set of numbers with a difference of 2 is a factor pair of 48? answer choices 2 and 4 4 and 6 6 and

ehidna [41]

Answer:

6 and 8

Step-by-step explanation:

All you have to do is find the difference between the numbers in each factor pair and make sure the factors combine to give 48.

2 and 4 . . . . . have a difference of 2, but 2·4 ≠ 48

4 and 6 . . . . . have a difference of 2, but 4·6 ≠ 48

6 and 8 . . . . . have a difference of 2, and 6·8 = 48

24 and 2 . . . . do not have a difference of 2

Answer:

$x = 39$

Step-by-step explanation:

Based on the given conditions, write: $x=\frac{13}{1-\frac{2}{3}}$

Find common denominator and write numerators above common denominator: $x=\frac{\frac{13}{3-2} }{3}$

Calculate the sum or difference: $x=\frac{\frac{13}{1} }{3}$

Divide the fraction by multiplying its reciprocal: $x=13*3$

Calculate the product or quotient: $x=39$

Answer: $x=39$

A woman spent two thirds of her money she lost two thirds the remainder and then had $4 left how much money did she start with

Lisa [10]

Answer

Find out how much money did she start with.

To proof

let us assume that the money she had be x.

As given

woman spent two thirds of her money

$Money\ spent = \frac{2x}{3}$

Money she had after spent two thirds of her money = Total money - money spent

$= x - \frac{2x}{3}$

$= \frac{1x}{3}$

As given she lost two thirds the remainder

$=\frac{2}{3}\times ( money\ she\ had\ after\ spending\ two\ thirds\ of\ her\ money)$

$= \frac{2}{3} \times\frac{1x}{3}$

we get

$=\frac{2x}{9}$

Money she had after lost two thirds the remainder = Money she had after spent two thirds of her money - she lost two thirds the remainder

$= \frac{1x}{3} - \frac{2x}{9}$

$= \frac{1x}{9}$

As given

she had $4 left

thus

$\frac{1x}{9} = 4$

x = $36

she start with $36.

Hence proved
