On the coordinate plane shown, each grid unit represents 10 feet. Polygon QRST has vertices Q(20, 10), R(−20, 10), S(−20, −20), and T(20, −20), and represents the floor plan of a room. Find the perimeter and area of the room.

Answer:

96

Step-by-step explanation:

Answer: 96

Step-by-step explanation:

84.48/0.88

The first step to dividing decimal numbers is to convert them into whole numbers. You can do this by multiplying 1 followed by as many zeros as decimal numbers there are. In this case, we have 2 decimal numbers, therefore, we must multiply by 1 followed by 2 zeros rather 100.

84.48*100/0.88*100

8448/88=96

Step-by-step explanation:

Because 14-6= 8 and then 14+8= 22

Answer:

m∠b = 23 degrees

Step-by-step explanation:

complementary angles are two angles that add up to 90 degrees so 90-67=23

Answer:

4 x minus 3 y = 16. 8 x minus 6 y = 34

Step-by-step explanation:

2 x + 8 y = 15. 4 x + 16 y = 30.

Multiply the first equation by 2

4x +16y = 30

They are identical so they are the same line so there are infinite solutions

2 x - y = 18. 4 x + 2 y = 38.

Multiply the first equation by 2

4x -2y = 36

Add to the first equation

4x -2y = 36

4 x + 2 y = 38.

-----------------------

8x =74

This has a solution

4 x + 7 y = 17. 8 x - 14 y = 36.

Multiply the first equation by 2

8x +14y = 34  add to the second equation

8x +14y = 34

8 x - 14 y = 36.

------------------------

16x = 70

This has a solution

4 x - 3 y = 16. 8 x - 6 y = 34.

Multiply the first equation by -2

-8x + 6y = -32

Add to the second

-8x + 6y = -32

8x - 6y = 34

---------------------------

  0 = 2

This is never true so there is no solution

Answer:

Last one:

4x minus 3y = 16

8x minus 6y = 34

Step-by-step explanation:

4x - 3y = 16

y =(4x - 16)/3

y = (4/3)x - 16/3

8x - 6y = 34

y =(8x - 34)/6

y = (4/3)x - 17/3

These are two distinct parallel lines, hence will never meet

Therefore no solutions

The -5 in the point is your x value, so you will plug in the -5 and then solve.

-5-5y=-15

-5y=10

y=-2

The missing value is -2.

Let me know if you need further explanation, and I hope this helps

Answer:

y=2

Step-by-step explanation:

x-5y=-15

-5-5y=-15

-5y=-10

y=2

Answer:

about $1.22

Step-by-step explanation:

divide 3.68 by 3 and the closest answer is 1.22

Answer:

$1.22

Step-by-step explanation: it says for 3 notebooks the cost is $3.68 so you have to divide that by 3 to get the cost of each individual notebook

Answer:

D.)The two variables are the number of crackers and the number of calories.

Step-by-step explanation:

The number of crackers is the independent variable, and the number of calories is the dependent variable.

The point (6, 42) is on the line

The number of crackers are graphed on the x-axis, and calories are graphed on the y-axis.

Answer:

The Third option is correct.

Step-by-step explanation: just got it right on edge

Answer:

Step-by-step explanation:

We have that the focus is at (p,0) and that the directrix is x=-p. Take the point (-p,0) of the directrix. We know that the vertex of the parabola is at the middle point ot the line segment that joins the points (p,0) and (-p,0). To get the middle piont, we take the average coordinate by coordinate. That is, the middle point is [tex](\frac{-p+p}{2}, \frac{0+0}{2}) = (0,0)[/tex]. The general formula of a parabola of vertex (h,k) that opens to the right or to the left is given by

[tex](y-k)^2 = 4p(x-h)[/tex]

Where |p| is the distance from the focus to the vertex. If the parabola opens to the right, then p>0 and p<0 otherwise. In our case, h =0=k, so we get that

[tex]y^2 = 4px[/tex]

Answer:

y^2 = 4px

Answer:

The first one is the better deal.

Step-by-step explanation:

The first one is the better deal =====

30% of 3 = 0.9

0.9 = 90

10% of 1 = 0.1

0.1 = 10

So the better deal would be 10% of 1

Answer: y = 2x + 1

Answer:

story 1

Step-by-step explanation:

because it says 2 higher than -2 so -2+2 is 0

Answer:

So, the first one is not proportional and therefore has no multiplier.

You are right on the second on both counts!

Step-by-step explanation:

You just need to divide the x's by the y's (individually) in order to determine what they are multiplied by. And the answers you get for the first one will be 5, 6, and 7. Because the numbers are different, they are not proportional.

48π cm^3

Step-by-step explanation:

The formula for the volume of a cone is...

[tex]V=\frac{1}{3}\pi r^2h[/tex]

We can plug everything we know from the photo into the equation, but note that the picture gives us the diameter, which is 8, instead of the radius. The radius is half of the diameter, so the radius will be 4. Also we will be leaving pi as it is, instead of changing it to 3.14.

[tex]V=\frac{1}{3}*(\pi *4*4*9)[/tex]

[tex]V=\frac{1}{3}*(144\pi )[/tex]

V = 48π

The paper cone can hold 48π cubic centimeters of water.

Answer:

Step-by-step explanation:

d = 8 cm

r =8/2 = 4 cm

h = 9cm

Volume of cone = (1/3)πr²h

[tex]=\frac{1}{3}\pi *4*4*9\\[/tex]

= 4*4*3*π

= 48π cubic centimeteres

Answer:

Step-by-step explanation:

Diameter is 7cm

radius is diameter/2 = 7cm/2 = 3.5cm

Answer:

[tex]diameter = 7 \: \: cm \\ radius = 3.5 \: \: cm[/tex]

Step-by-step explanation:

[tex]d = 7 \: \: cm[/tex]

[tex]r = \frac{d}{2} \\ r = \frac{7}{2} \\ r = 3.5cm[/tex]

Answer: [tex]x=4.7434[/tex]

Step-by-step explanation:

Use the pythagorean theorem [tex]a^{2} +b^{2} =c^{2}[/tex]

plug in and solve

[tex]x^{2} +3x^{2} =(3\sqrt{10}) ^{2}[/tex]

[tex]4x^{2} =90[/tex]

[tex]x^{2} =22.5[/tex]

[tex]x=4.7424[/tex]

if you need to solve for the sides

3x = 3(4.7434) = 14.2302
