Answer: 23/36

Step-by-step explanation:

[tex]\frac{3}{4} -\frac{7}{9} +\frac{2}{3}[/tex]

You need to find a common denominator.

The common denominator is 36. You have to get all denominators to 36.

How to do that?

Example = [tex]\frac{3}{4} *\frac{9}{9} =\frac{27}{36}[/tex].

Do that to all the fractions.

[tex]\frac{27}{36} -\frac{28}{36} +\frac{24}{36} = \frac{23}{36}[/tex]

Explanation:

Let's say that this tub is 72 gallons. I picked this number since 12*6 = 72. You can pick any number you want, but I picked this number so we end up with whole number results as shown below.

Tap X can fill the 72 gallon tub in 12 minutes. Its rate is 72/12 = 6 gallons per minute. Tap Y has a rate of 12 gallons per minute because 72/6 = 12.

Add the two unit rates: 6+12 = 18

If the two taps are opened at the same time, then they will work at a rate of 18 gallons per minute.

Let x be the number of minutes. The expression 18x represents how much of the tub is full after x minutes. Set this equal to the 72 we started with earlier and solve for x.

18x = 72

x = 72/18

x = 4

It will take 4 minutes if both taps are running at the same time.

Answer:

44 millimeters

Step-by-step explanation:

The ratio is set up as millimeters : meters

On the map, 4 millimeters : 9 meters

The actual length ratio is represented as x millimeters : 99 meters

Since we know its proportional, we can set up the equation:

4/9 = x/99

Solve:

4/9 = x/99

4 * 99 = 9x

396 = 9x

x = 44 millimeters

Another Way

Since we already know it is proportional, 99 = 9 x 11

So we can multiply 4 x 11 to get 44 millimeters.

Answer:

875 books

Step-by-step explanation:

1st machine 700 books/40 hours = 17.5 books/hr

2nd machine printed 2x or 35 books/hr

25 hours x 35 books/hr = 875 books

Given,

A glass block window is made of two different-sized glass squares.

The window has side lengths of 40 inches. The large glass squares have side lengths of 10 inches.

Step-by-step explanation:

Las dos rectas que se cortan formando un ángulo de 135° son secantes. (Opción: C)

Las dos rectas en cuestión no pueden ser paralelas pues sus pendientes son distintas y, por consiguiente, se intersecan en algún lugar del plano.

Tampoco pueden ser semirrectas pues el enunciado indica que existen dos rectas y las rectas no tienen principio ni fin.

Mucho menos pueden ser perpendiculares, pues el ángulo es distinto a 90°.

En consecuencia, las dos rectas que se cortan formando un ángulo de 135° son secantes. (Opción: C)

Answer:

53/8 = 53/8

Step-by-step explanation:

Here we will simplify 53/8 to its simplest form and convert it to a mixed number if necessary.

In the fraction 53/8, 53 is the numerator and 8 is the denominator.

When you ask "What is 53/8 simplified?", we assume you want to know how to simplify the numerator and denominator to their smallest values, while still keeping the same value of the fraction.

We do this by first finding the greatest common factor of 53 and 8, which is 1.

Then, we divide both 53 and 8 by the greatest common factor to get the following simplified fraction:

58/3

Therefore, this equation is true:

53/8 = 53/8

If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.

53/8 = 6 5/8
