Yes, all you do is 540x42 which gives you 22680 and the pool only needs to be filled up with 22410, so yes

What is the slope for 1.(4,9) & (1,6)

Semenov [28]

Step-by-step explanation:

1.(4,9) & (1,6)

m=y²-y¹/x²-x¹

m=6-9/1-4

m=-3/-3

m= 1

2.(5,3) & (5,-9)

m=y²-y¹/x²-x¹

m=(-9)-3/5-5

m=-12/0

3.(2,1) & (8,9)

m=y²-y¹/x²-x¹

m=9-1/8-2

m=8/6

m= 4/3

4.(14,-8) & (7,-6)

m=y²-y¹/x²-x¹

m=(-6)-(-8)/7-14

m=2/-7

m= -2/7

5.(4,-3) & (8,-3)

m=y²-y¹/x²-x¹

m=(-3)-(-3)/8-4

m=0/4

m=0

6.(-11,1) & (-2,6)

m=y²-y¹/x²-x¹

m=6-1/(-2)-(-11)

m=5/9

The bases of a trapezoid lie on the lines y=2X +7 and y= 2X -5. Write the equation that contains the midsegment of the trapezoid

ryzh [129]

Given:

The bases of a trapezoid lie on the lines

$y=2x+7$

$y=2x-5$

To find:

The equation that contains the midsegment of the trapezoid.

Solution:

The slope intercept form of a line is

$y=mx+b$

Where, m is slope and b is y-intercept.

On comparing $y=2x+7$ with slope intercept form, we get

$m_1=2,b_1=7$

On comparing $y=2x-5$ with slope intercept form, we get

$m_2=2,b_2=-5$

The slope of parallel lines are equal and midsegment of a trapezoid is parallel to the bases. So, the slope of the bases line and the midsegment line are equal.

$m=m_1=m_2=2$

The y-intercept of one base is 7 and y-intercept of second base is -5. The y-intercept of the midsegment is equal to the average of y-intersects of the bases.

$b=\dfrac{b_1+b_2}{2}$

$b=\dfrac{7-5}{2}$

$b=\dfrac{2}{2}$

$b=1$

So, the y-intercept of the required line is 1.

Putting m=2 and b=1 in slope intercept form, we get

$y=2x+1$

Therefore, the equation of line that contains the midsegment of the trapezoid is $y=2x+1$ .

- Maria wants to buy a ring that costs $67.00. She has a coupon for 25% off.

Vilka [71]

Answer:

$16.75

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 67 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 67 is 100%, so we can write it down as 67=100%.

4. We know, that x is 25% of the output value, so we can write it down as x=25%.

5. Now we have two simple equations:

1) 67=100%

2) x=25%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

67/x=100%/25%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 25% of 67

67/x=100/25

(67/x)*x=(100/25)*x - we multiply both sides of the equation by x

67=4*x - we divide both sides of the equation by (4) to get x

67/4=x

16.75=x

x=16.75

now we have:

25% of 67=16.75
