Help me simplify the expressions pleaseddees.....!!!! It's in a picccc​

Answer:

see explanation

Step-by-step explanation:

The perimeters of the similar figures have the same ratio as the sides.

ratio of perimeters = [tex]\frac{11}{6}[/tex]

ratio of areas = 11² : 6² , that is 121 : 36

ratio of areas = [tex]\frac{121}{36}[/tex]

Answer:

1440 degrees.

Step-by-step explanation:

125 + 140 + 160 = 425 degrees.

The remaining angles are each 145.

The exterior angles of all polygons sum to 360 .

So we have exterior angles sum of the 3 given angles

= (180-125) + ( 180-140) + (180-160)

= 55 + 40 + 20 = 115.

So the remaining vale of the sum is 360 - 115

= 245 degrees.

An internal angle of 145 will give an external one of 35 degrees.

245/35 = 7.

So there are 7 145 degree angles in the polygon.

Sum of the interior angles is therefore:

425 + 7*145

= 1440 degrees.

This is a 10 sides polygon ( a decagon).

Answer:

x over y , but you'll have to do y over x to get the answer .

Answer:

That is true

Step-by-step explanation:

9:2 = 18:4

9x2=18

2x2=4

Thus, this answer is true.

Answer:

Yes, because if you simplify 18:4, it would simplify to 9/2. Both ratios are equivalent.

Step-by-step explanation:

first, let's break the equation down.

y=7x-4

-4 represents your staring coordinate, or your y-intercept. This is because -4 does not have an x after so you know it is equal to your y value. So you start at (0,-4)

Now all you need to do is the y=7x part.

The 7x represents your slope.

Slope is equal to rise/run or y/x.

So for each coordinate, you go up 7 and to the right 1.

(0,-4)

The solution to the system of equations x + 2y = 1  and -3x-2y = 5 is:

x  = -3,  y = 2

The given system of equations:

x  +  2y  =  1............(1)

-3x - 2y  =  5..........(2)

This can be written in matrix form as shown:

Answer:

50%

Step-by-step explanation:

The percent gain is calculated as

[tex]\frac{gain}{original}[/tex] × 100%

gain = 27 - 18 = 9 , then

percent gain = [tex]\frac{9}{18}[/tex] × 100% = [tex]\frac{1}{2}[/tex] × 100% = 50%

Answer:

Step-by-step explanation:

Answer:

We have to represent 1/4 in the number line .

So simply will first write it in Fraction form that is

So we have to represent it on number line .

1/4 we have to mark on the right side of number line because it is a positive number having no negative number . That is why we will mark it on the right side of the number line .

As we know the denominator is 4 so between every number we will keep four points distance.

After the zero the first point is number 1 and number 2 and number 3 and so on ...

The four points will consider number 1 , 2 , 3 , 4 and so on ...number after four points I have written 1 because there is the denominator 4 so we should keep 4 points distance in each number .

So , The number 1 we will mark and write the denominator 4
