Answer:

Step-by-step explanation:

1). [tex]8\frac{1}{4}[/tex] ÷ [tex]\frac{3}{4}[/tex]

= [tex]\frac{33}{4}[/tex] ÷ [tex]\frac{3}{4}[/tex]

= [tex]\frac{33}{4}\times \frac{4}{3}[/tex]

= 11

2). [tex]3\frac{1}{3}[/tex] ÷ [tex]\frac{10}{3}[/tex]

= [tex]\frac{10}{3}[/tex] ÷ [tex]\frac{10}{3}[/tex]

= [tex]\frac{10}{3}\times \frac{3}{10}[/tex]

= 1

3). [tex]\frac{5}{4}[/tex] ÷ [tex]\frac{1}{4}[/tex]

= [tex]\frac{5}{4}\times \frac{4}{1}[/tex]

= 5

4). [tex]\frac{25}{4}[/tex] ÷ [tex]6\frac{1}{4}[/tex]

= [tex]\frac{25}{4}[/tex] ÷ [tex]\frac{25}{4}[/tex]

= [tex]\frac{25}{4}\times \frac{4}{25}[/tex]

= 1

5). [tex]11\frac{1}{4}[/tex] ÷ [tex]\frac{9}{4}[/tex]

= [tex]\frac{45}{4}[/tex] ÷ [tex]\frac{9}{4}[/tex]

= [tex]\frac{45}{4}\times \frac{4}{9}[/tex]

= 5

6). [tex]3\frac{1}{7}[/tex] ÷ [tex]\frac{2}{7}[/tex]

= [tex]\frac{22}{7}[/tex] ÷ [tex]\frac{2}{7}[/tex]

= [tex]\frac{22}{7}\times \frac{7}{2}[/tex]

= 11

Now we can classify the expressions by their quotients as 1, 5 and 11.

Answer:

-20x

Step-by-step explanation:

the number outside of the parenthasis must be distributed to all numbers with in them.

ex:

-3(2x + 5) = -6x -15

Answer:

abc because they are always a repeating decimal

Answer:

y= -11/7x+8

move variables to the right hand side and change its sign

-7y=-56+11x

change the signs on both sides of the equation

7y=56-11x

divide both sides by 7

y=8-11/7 x

reorder the terms and get y= -11/7x+8

Answer:

It is 5.5 miles/hour if you are trying to figure out how fast john runs.

Step-by-step explanation:

if john run 2 mile/hour faster than lucy, you just have to add how fast lucy is running by 2. This will equal john's miles/hour. now you times 5.5 by how many hours he runs.

Answer:

x=-2/23

Answer:

x = 66/7 & area = 132/7

Step-by-step explanation:

7x-9=0

x=9/7

substitute value of x in 5x-3;

5(9/7)+3=66/7

Then, a*a,

thus, 2(66/7) = 132/7

Answer:

50

Step-by-step explanation:

because <TMS is a right angle 90 degrees and also it is congruent with <TMR

so 90 - 40 = 50 that is the correct answer.

Answer:

r(180°,0) is a rotation of 180° degrees over the origin.

Notice that this rotation moves our figure to the opposite quadrant (so a translation of two quadrants).

Then this is equivalent to:

A reflection over the x-axis followed by a reflection over the y-axis.

Or.

A reflection over the y-axis followed by a reflection over the x-axis.

There is another possible reflection, but it depends on where is our figure.

If the figure is in the first or third quadrant, a reflection over the line y = -x is equivalent to the rotation.

If the figure is in the second or third quadrant, then the reflection over the line y = x is equivalent to the rotation.

We can combine those two and write:

A reflection over the line y = (-1)^n*x.

Where n is the number associated with the quadrant where the figure is in.

Answer:

43 ft apart

Step-by-step explanation:

They are forty feet apart, because the bird is 40ft away from the ground, and then there is an extra 3 feet below the ground, so you add them up to get 43 ft

Answer:

y=8

Step-by-step explanation:

The two triangles are similar, but scaled to a ratio.

Given the ratio of two corresponding sides AC and NL, the scale is 10:5 which is 2. So, the side MN when scaled to the same ratio, the corresponding side's length y = 4*2 = 8 ft

Step-by-step explanation:

Given:

Butterfly can travels = 82 km each day.

Total distance = 3936 km.

To find:

The number of day it takes to travel the given distance.

Solution:

Let the number of days it takes to travel be d.

Butterfly can travels about 82 km each day.

So, distance traveled by it in d days = (82d) km

Total distance is about 3936 km.

[tex]82d=3936[/tex]

To isolate d , we need to divide both sides by 82.

[tex]\dfrac{82d}{82}=\dfrac{3936}{82}[/tex]

[tex]d=48[/tex]

Therefore, the required number of days is 48.
