Opposite sides of parallelogram ABWC are equal.

Since point C bisects VW, VC=CW

And 3x+1=CW and CW=1/2 of VW

So:

2(3x+1)=7x-3

x=5

Then VW=7(5)-3=32

To find the value of expression [tex]p^3+q^3-r^3-3pqr[/tex].

Substitute all values p=4,q=-3,and r=2 in the expression, we get

[tex]4^3+(-3)^3-(2)^3-3(4)(-3)(2)\\\\=64-27-8+72\\\\=101[/tex]

HELP

Answers

Answer:

Step-by-step explanation:

We need to find 5 sides of the cube and 4 sides of the pyramid.

For the cube, each side's area is [tex]s^{2}[/tex] with s being the side length. Since there are 5 sides, it would be 5 x  [tex]s^{2}[/tex]. s=15, so it would be 5 x 15 x 15, which is 75 x 15 which simplifies into 1125.

For the pyramid, we need to find the area of all 4 triangles. They are all the same triangle, each with a base of 15 and a height of 9.  So one triangle's area is 9 x 15/2 = 67.5 --> Since there are 4 triangles, the area of all of them would be 67.5 x 4 which is 270.

1125 + 270 = 1395 cubic ft. (or [tex]ft^{3}[/tex])

Instructions: Find the measurement of the diagonal indicated in the following parallelogram.
Help!!

Answers

Answer:

VX = 24

Step-by-step explanation:

Given :

VJ = 12 units

To find :

VX = ?

Solution:

Since, diagonal of a parallelogram bisect each other.

By this property,

m(VX) = 2[(VJ)]

m(VX) = 2(12)

          = 24 units

Therefore, measure of the diagonal (VX) of the given parallelogram is 24 units.

Draw a line with a slope of -1/2 going through the point (4,5) already graphed for you. At what point does this line cross the y-axis?

Answers

Answer: What is the slope of this line? It's the 'm' term in y=mx+b. In this example, m=1. Therefore the slope of the line is 1, or said another way, the line goes "up" one unit every time it goes "over" one unit.

What is the y-intercept of the line? That's the 'b' term, so it's also 1. That means that when x is 0, y=1. Go ahead and plug x=0 into that equation to verify for yourself.

Step-by-step explanation:

Answer: 7

Equation: y= -1/2x + 7

Step-by-step explanation:

A slope of -1/2 means every x-value you go up by, the y-value goes down by 1/2.

To find an y-intercept you have to go back 4 x-values. So then you need to go up four 1/2 y-values. (simply 2 y-values).

For a company picnic, Todd fills 30 paper cups with ketchup and Yuki fills 27 paper cups with ketchup. Each paper cup holds 1 ounce. Later, Todd and Yuki learn that two other company employees completed exactly the same task. Question 1 Part A Write a numerical expression to find how many ounces of ketchup the four employees prepared.

Answers

Step-by-step explanation:

Todd fills 30 paper cups with ketchup and Yuki fills 27 paper cups with ketchup.

Each paper cup holds 1 ounce

Todd = 30 * 1 = 30 ounces

Yuki = 27 * 1 = 27 ounces

Total ounces = 30 + 27

Later, Todd and Yuki learn that two other company employees completed exactly the same task.

Total ounces = 2 (30 + 27)

Answer:2(30+27)

Step-by-step explanation:

the other company is doing the same thing so you multiply by 2  

and we have 30 and 27 so we use those numbers to make

2(30+27)

Find X, BA, AC, and BC of isosceles triangle BAC.
BA= 2x-5; AC = 3x -9;
BC = X-2

Answers

Answer:

BA = 3

AC = 3

BC = 2

x = 4

Step-by-step explanation:

Find x

BA and CA are equal            Given

2x - 5 = 3x - 9

Subtract 2x from both sides

- 5 = 3x - 2x - 9

- 5 = x - 9            

Add 9 to both sides.

- 5 + 9 = x - 9 + 9

4 = x

=========================

BA = 2x - 5

BA = 2*4 - 5

BA = 3

AC = 3x - 9

AC = 3*4 - 9

AC = 12 - 9

AC = 3

BC = x - 2

BC = 4 - 2

BC = 2

Summary

BA = 3AC = 3BC = 2x = 4

An online store sells two types of speaker docks for smartphones. The higher-priced speaker dock sells for $170 and the lower-priced speaker dock sells for $90. Last week the store sold four times as many lower-priced speaker docks as higher-priced speaker docks. Combined sales totaled $4,770. How many lower-priced speaker docks did it sell?

Answers

Answer:

9

Step-by-step explanation:

Let us represent

Low priced = x

High priced = y

An online store sells two types of speaker docks for smartphones. The higher-priced speaker dock sells for $170 and the lower-priced speaker dock sells for $90. Combined sales totaled $4,770.

170x + 90y = $4770

Last week the store sold four times as many lower-priced speaker docks as higher-priced speaker docks.

4x = y

Substitute 4x for y

170x + 90y = $4770

170x + 90(4x) = $4770

170x + 360x = $4770

530x = $4770

x = 4770/530

x = 9

The number of lower-priced speaker docks it sold was 9

plz help me Which expression is equivalent to 24 + 64? (5 points)
a 8(3 + 64)
b 8(16 + 56)
c 8(3 + 8)
d 8(16 + 64)

Answers

The answer would be C, because 24+64 equals 88. And if you complete the expression 8(3+8), first solve the equation in the parentheses aka 8+3. Which gets you too 11. And now you multiply 8 by 11, and get 88 as your answer.

  x = 3

Step-by-step explanation:

The triangle is equilateral, so each side is equal to the others:

  x = 3 . . . . . . . . divide by 2

A system of linear equations is given as x + 3y = 36 and 4x + 5y = 9. Which of the following is a possible first step when solving by substitution? *
1 point
Rewrite the first equation as x = 36 – 3y.
Rewrite the first equation as y = 1/3x + 12.
Rewrite the second equation as x = 9 – 5/4y .
Rewrite the second equation as y = 9 + 4x.

Answers

Answer:

Rewrite the first equation as x = 36 – 3y.

Step-by-step explanation:

x + 3y = 36 (1)

4x + 5y = 9 (2)

Using substitution method

From (1)

x = 36 - 3y

Substitute x = 36 - 3y into (2)

4x + 5y = 9

4(36 - 3y) + 5y = 9

144 - 12y + 5y = 9

- 12y + 5y = 9 - 144

-7y = -135

y = -135 / -7

y = 19.3

There is an error with the second equation, 4x + 5y can not be equal to 9

Nevertheless, the first step when solving by substitution is:

Rewrite the first equation as

x = 36 – 3y.

A snowboarder leaves an 8-foot tall ramp with an upward velocity of 28 feet per second. The function h =− 16t 8t gives the height h (in 2 + 2 + 8 feet) of the snowboarder after t seconds. When does the snowboarder hit the ground?

Answers

Answer:

2 seconds

Step-by-step explanation:

Given that:

h = -16t² + 28t + 8

Using quadratic formula:

[tex]\dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

where;

a = -16

b = +28

c = +8

[tex]= \dfrac{-(28) \pm \sqrt{(28)^2 - 4(-16)(8)}}{2(-16)}[/tex]

[tex]= \dfrac{-(28) \pm \sqrt{784+512}} {-32}[/tex]

[tex]= \dfrac{-(28) + \sqrt{784+512}} {-32} \ \ OR \ \ = \dfrac{-(28) - \sqrt{784+512}} {-32}[/tex]

[tex]=- \dfrac{1}{4} \ \ OR \ \ 2[/tex]

Since we are considering the positive value; Then it will take the snowboarder 2 seconds before it hits the ground.
