Answer:

28

Step-by-step explanation:

21 is 75% percent of 28!

I hope this helps <3

Answer:

28

Step-by-step explanation:

i don't know how to explain it exactly

[tex]~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ C(\stackrel{x_1}{1}~,~\stackrel{y_1}{0})\qquad D(\stackrel{x_2}{-7}~,~\stackrel{y_2}{2}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left(\cfrac{ -7 + 1}{2}~~~ ,~~~ \cfrac{ 2 + 0}{2} \right)\implies \left(\cfrac{-6}{2}~~,~~\cfrac{2}{2} \right)\implies (-3~~,~~1)[/tex]

Answer:

Midpoint: (-0.5, -1)

Step-by-step explanation:

Solution: M=([tex]x m[/tex],[tex]ym[/tex])/2 or ([tex]x[/tex]+[tex]x[/tex]/2, [tex]y[/tex]+[tex]y[/tex]/2)

add the first [tex]x[/tex] coordinate plus the second [tex]x[/tex] coordinate

do the same for the two [tex]y[/tex] coordinates

then divide them both by 2

should look something like this: (1+0 /2, -7+2 /2)

[tex]x[/tex]= 1+0= 1 / 2 + 0.5 or one half 1/2

[tex]y[/tex]= -7+2= -5 / 2 = -2.5 or four one half -2 1/2

BUT we are not done here, since we cant divide 1/2 no more because it will still give us the same answer (0.5) we move into the next number, -2 1/2, -2 x 1/2 = -1

So our answer is (-0.5, -1)

Answer:

0.6

Step-by-step explanation:

You count how many pieces there are in total, and then you subtract the blue pieces from the total which is 3.  Then you need to convert 5/8 into a decimal.

Let solve:

  [tex]2(x+16) = 6x\\2x + 32 = 6x\\32 = 4x\\4x = 32\\x = 8[/tex]

Thus x = 8

Answer:

4) 0.425, 17/40, 42.5%
5) 0.875, 7/8, 87.5%

Step-by-step explanation:

4) 17/40= 0.425, 17/40 is simplified to the lowest form already, and (0.425x100)x 1/100

5) 35/40=0.875, 35/40=7/8, and (0.875 * 100) * 1/100= 87.5%


i hope htis helps sorry if i got anything wrong

Answer:

The slope of (-5,10)(-3,0) is -5

The slope of (0,1)(4,-4) is -5/4

Step-by-step explanation:

The slope-intercept form is y=mx+b

In order to find slope, do y2-y2/x2-x1

x and y are the coordinates and then you just plug them in

Answer:

-3

Step-by-step explanation:

when a number is outside of a parenthesis I and is nothing inside, this mean to multiplay, after remember the rules of multiplay and divide intergers, on this case is negative x positive is equal to negative.

(-1)3 = -3

Answer:

the answer is 6 cm

Step-by-step explanation:

Here’s one way you can solve this problem.

A zoom setting of one hundred twenty percent means that the dimensions of the new copy will be one hundred twenty percent of the dimensions of the original drawing.

First, write the scale that expresses the ratio of the original percent to the copy percent, one hundred to one hundred twenty.

Then, let h represent the height of the copy and write the ratio of copy to original as five centimeters to h centimeters.

Next, write a proportion that equates the two ratios. One hundred to one hundred twenty equals five to h.

Then, cross multiply the terms of the proportion. One hundred twenty times five equals one hundred h.

Next, multiply to get six hundred equals one hundred h.

Finally, divide both sides by one hundred to find h. h equals six.

So, the longer dimension of the new drawing is six centimeters, which is one hundred twenty percent of five centimeters.

Answer:

3 × [tex]\frac{2}{8}[/tex]

Step-by-step explanation:

The three rectangles add up 6/8 of the unit

The correct  expression is:

3 × [tex]\frac{2}{8} =\frac{(3)(2)}{8} =6/8[/tex]

I think this is correct.

Step-by-step explanation:

1/-7 =  -0.14285714285714

If you round it to the nearest hundredth, it will be -0.14.

I hope you meant negative :)

Answer:

5 1/3

Step-by-step explanation:

If you split up this shape into a triangle on top and a rectangle on the bottom you can do

(3 2/3 x 2) / 2

Then you do

5 x 1/3

Then add up the sums and you get the area :)

Answer:

4

Answer:

its the first option on the paper

Answer:

A = picture attached

B = 51 in²

Step-by-step explanation:

The picture attached is the answer for part A. You use the dimensions you already know from the first picture to fill in the net of the slice of pie.

Area of the triangle = 1/2 (base × height)

A = 1/2 (4 × 6) = 1/2 (24) = 12

The area of the triangle is 12. The top is a triangle, but the bottom is also a triangle with the same area. Therefore, the area of the two triangles combined is 24 in². Next, we have to find the area of the rectangle at the sides of the pie.

Area of rectangle = length × width

A = 5 × 2.5 = 12.5

Since there are two rectangles with the same area on both sides of the pie, we can double it and get 25 in². We still have one rectangle left, the one at the back of the pie.

A = 6 × 2.5 = 15

Add the areas altogether to get the answer.

24 + 12.5 + 15 = 51.5 in²

I hope this helps. Sorry if Part B's answer is wrong.

Answer:

9.7 I think because if you do 480x9.7 it will equal 4656.

Answer:

p x 7 = d

Step-by-step explanation:

If the If the amount of meat is 3 and the cost is 21 in dollars you divide 21 by 3 and the answer is 7 and to see if the answer is 7 for the rest of the questions divide 35 by 5 that equals to 7 same thing with 49 divided by 7 that equals to 7.

Answer:

if this is area than

1- 55

2- 28

3-  48

4- 84

Step-by-step explanation:

Answer and explanation:

First, the domain is all real numbers except 0, since x = 0 is the asymptote.

D: x ∊ R, x ≠ 0

or

D: (-∞, 0) ∪ (0, ∞)

The range is everything below y = 0.

R: y < 0

or

R: (0, -∞)

Next, this function is never constant so there are only intervals of increasing and decreasing. The intervals meet at x = 0.

inc: x > 0

dec: x < 9

or

inc: (0, ∞)

dec: (0, -∞)
