12. UZ, VX, and TW are medians of Triangle TUV. If YX = 8, find VY.​

Answers

Answer:

VY = 16

Step-by-step explanation:

The median of a triangle is the segment that joins a vertex and the midpoint of the side opposite to this vertex.The point of intersection of the medians of a triangle, divide each median at ratio 2: 1 from the vertex.

In the given figure

∵ TUV is a triangle

UZ, VX, and TW are medians

∵ UZ ∩ VX ∩ TW at point Y

∴ Y is the point of intersection of the 3 medians

→ By using the 2nd rule above

∵ The point Y divide VX at the ratio of 2: 1 from the vertex V

VY: YX = 2: 1

∴ [tex]\frac{VY}{YX}[/tex] = [tex]\frac{2}{1}[/tex]

→ By using cross multiplication

∵ VY × 1 = YX × 2

VY = 2YX

∵ YX = 8

∴ VY = 2(8)

VY = 16

Find volume and surface area

Answers

Volume of cone = (pi • r^2 • h)/3

If the diameter of the circle on the cone is 8 then the radius is 4.

V = (pi • 4^2 • 9)/3

V = 48pi in^3

Surface are of cone given radius.
= pi • r^2 + pi • r • square root of r^2 + h^2

A = 3.14 • 4^2 + 3.14 • 4 square root of 4^2 + 9^2

A = 16 • 3.14 + 4 square root of 97 • 3.14

A = 50.24 + 4 square root of 304.58

A = 50.24 + 69.81

A = 120.05

how do you Round 96,286 to the nearest thousand.

Answers

Answer:

The correct answer is 96,000

Step-by-step explanation:

To round you look at the thousands place and there is a 9 then you look at the number to the right of it which is 2 and it is lower than 5 since it is lower than five it rounds down so the correct answer is 96,000.

HAVE A GOOD DAY!

Answer:

96,000

Step-by-step explanation:

 If the number on the right of the nearest thousand is lower than 5 the nearest thousand and the numbers to the left of it stay the same, while the numbers on the right turn into 0(zeros) but if the number in the right of the nearest thousand is 5 or grater then the nearest thousand would go up one digit while the numbers on the left of the nearest thousand stay the same, while the numbers on the right of the nearest thousand turn to zeros.

This can be solved by solving a system of linear equations that is shown above.

write an equation of the line and interpret the slope ​

Answers

Answer:

Step-by-step explanation:

Slope of this line will be= m= (600-200)/(1-5)

m = 400/-4 = -100

Eq of line will be:

(y-y1)=m(x-x1)

y-200=-100(x-5)

y-200+100x-500=0

100x+y-700 = 0

To write equation in slope-intercept form

y=mx+c

just seperate "y"

y=-100x+700

Hey there!

The answer to your question is [tex]y = -100x + 500[/tex]

To write this equation in slope-intercept form, first we must figure out the slope. We can do this using the formula

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]:

[tex]\frac{200-600}{5-1}[/tex]

[tex]\frac{-400}{4}[/tex]

[tex]-100[/tex]

Now, we have part of the equation: y = -100x + b. We have to find b, and we can do so by plugging in one of the points into the equation, like so:

[tex]600 = -100(1) + b[/tex]

[tex]600 = -100 + b[/tex]

[tex]500 = b[/tex]

Now, we have our equation:[tex]y = -100x + 500[/tex]

Hope it helps and have an amazing day!

20% of 1100 is 220, so two hundred and twenty students brought their lunch to school on Thursday (and every other school day).

Step-by-step explanation:

The day of the week is a distraction.  All you need to know is that 20% of 1100 students bring their lunch to school every day. 20% of 1100 is 200 + 20, or 220. So 220 students bring their lunch to school every day.

Multiply the second equation by [tex]-\frac{3}{2}[/tex] to isolate and solve for [tex]c[/tex]:

Answer:

One Slice of Pizza is $1.50

One cola is $0.75

Step-by-step explanation:

First, we need to define our variables:

x = pizza

y = cola

Next, we need to create two equations (one for Tanisha's order and one for Rachels order) using the information provided in the problem:

3x + 2y = 6.00

2x + 3y = 5.25

Now, we need to use one of the equations to solve for one of the variables:

3x + 2y = 6.00

2y = 6 - 3x

y = 3 - 1.5x

Next, we need to substitute y into one of the equations to find x:

2x + 3 (3 - 1.5x) = 5.25

2x + 9 - 4.5x = 5.25

-2.5x + 9 = 5.25

-2.5x = -3.75

x (or price per slice of pizza) = 1.50

Finally, we need to use the value we found for x to solve for y:

(2 x 1.5) + 3y = 5.25

3 + 3y = 5.25

3y = 2.25

y (or price per cola) = .75
