Answers

Answer:d + q = 40 -----> d = 40 - q

10d + 25q = 760

Substitute!

10(40 - q) + 25q = 760

400 - 10q + 25q = 760

15q = 360

q = 24

d = 40 - 24

Find angle YWX using the perpendicular or angle bisector method.

Answers

9x-28=5x-8
9x=5x+20
4x=20
x=5
(9x-28)+(5x-8)=
(17)+(17)=34
YMX= 34 degrees

Answer:

x = 5

Step-by-step explanation:

9x - 28 = 5x - 8 (because Y and X are equal, and XZ and YZ are equal)

add 8 to both sides

9x - 20 = 5x

subtract 9x from both sides

-20 = -4x

divide 4x from both sides

5 = x

x = 5

Your subtotal at the store was $58.89. You have a 30% off coupon. If the sales tax rate is 5.5%, what is the total price for your shopping trip?

Answers

Answer:

$43.48

Step-by-step explanation:

58.89x.30=17.68

58.89-17.68=41.21

41.21x.055=2.27

41.21+2.27= $43.48

Answer:

$43.49

Step-by-step explanation:

When you take of 30%, multiply by 0.7

When you add 5.5%, multiply by 1.055

Start with $58.89

Take off 30%: 0.7 * $58.89 = $41.22

Add 5.5%: 1.055 * $41.22 = $43.49

what is the slope of a line with endpoints (-11,5) and (5,-7)

Answers

Answer:

-6/8

Step-by-step explanation:

Slope=y1-y2/x1-x2

Where (X1,y1) is (-11,5) and (X2,y2) is(5,-7)

Slope=5+7/-11-5

=-12/16

= -6/8

So the slope is -6/8

Slope K = (y2-y1)/(x2-x1)
Point 1 = (-11,5) Point 2 = (5,-7)

Slope K = (-7-5)/(5+11) = (-12)/16 = -3/4

(x - 18)^2 = 1

Answers

Answer:

x=17 or x=19

Step-by-step explanation:

(x−18)^2=1

First, simplify both sides of the equation.

x*2−36x+324=1

Then subtract 1 from both sides.

x^2−36x+324−1=1−1

x^2−36x+323=0

Factor left side of equation.

(x−17)(x−19)=0

Then set factors equal to 0.

x−17=0 or x−19=0

x=17 or x=19

YW is the perpendicular bisector of ZT.
If TW = 3, YW = 8, and XZ = 12. Find XY.

Answers

Answer:

XY = 17 UNIT

Step-by-step explanation:

Given:

TW = 3

YW = 8

XZ = 12

Find:

XY

Computation:

TW = ZW = 3

So,

XW = 12 + 3

XW = 15

So

XY = √XW²+YW²

XY = √15²+8²

XY = √289

XY = 17 UNIT

Applying the definition of perpendicular bisector and the Pythagorean Theorem, the value of XY is calculated as: 17 units.

Recall:

A perpendicular bisector of a line divides a line segment into two equal halves.Also, it forms two opposite right angles on the point of bisection.

Considering the diagram attached below, we are given that:

[tex]TW = 3\\\\YW = 8\\\\XZ = 12[/tex]

We need to find the length of XY.

Applying the Pythagorean theorem:

[tex]XY = \sqrt{XW^2 + YW^2}[/tex]

XW = XZ + WZ

XZ = 12 (given)

WZ = TW = 3 (congruent segments)

Thus:

XW = 12 + 3

XW = 15

Plug in the values of XW and YW into [tex]XY = \sqrt{XW^2 + YW^2}[/tex]

Thus:

[tex]XY = \sqrt{15^2 + 8^2}\\\\\mathbf{XY = 17}[/tex]

I need to know how to graph and use a table to solve for y=3x+0

Answers

Answer:

Step-by-step explanation:

On a table, you'd have two columns: one for your input(x) and one for your output(y). If given an x value, put it into the equation to solve for y, and if you have a y value, put it into the equation for x. You can also come up with your own x values and put them into the equation if you need to create a table from scratch I'm not sure what you're asking but this will help you fill in a table. Here's and example for this equation.

X              Y

1                3

2               6

3               9

Graphs are pretty simple. Just find a value on the x-axis (horizontal), find the point on the line above or below this value, and look at what number it is for the y value. You can do this backwards if you need to find y when given x.

Question 3 40 pts
An object is attached to a spring that is stretched and released. The equation d = a (cos(bt)) models the distance, d, of the object in inches above or below the rest position as a function of time, t, in seconds. If a = 5 and b = 5 Approximately when will the object be 2 inches above the rest position? Round to the nearest hundredth, if necessary.

Answers

Answer:

The object will be 2 inches above the rest position when at approximately 0.23 seconds

Step-by-step explanation:

The given parameters are;

The equation that models the distance, d, of the object in inches above or below the rest position = a×(cos(b·t))

If a = 5 and b = 5, we have;

d = 5 × (cos(5 × t))

When the object is approximately 2 inches above the ground, we have;

d = 2 = 5 × (cos(5 × t))

cos(5 × t) = 2/5

5 × t = cos⁻¹(2/5) ≈ 1.16

t =  (cos⁻¹(2/5))/5 ≈ 1.16/5

t ≈ 0.23 s

The object will be 2 inches above the rest position when t ≈ 0.23 s.

If a circle with a diameter of 4 inches rotates 1000°, what distance will any one spot on
its edge actually travel?

Answers

We first convert from degrees to radians multiplying by π/180:

θ = 1000° × π/180 = 17.45 rad

The radius is:

r = d/2 = 4 in /2 = 2 inch

So, The distance traveled is given by the product of the angle in radians and the radius. This is:

d = θr = (17.45 rad)(2 inch) = 34.9 inch

Triangle CEN is congruent to Triangle CED. What property is shown by line segment CE being congruent to line segment CE?

Answers

Answer:

C. Reflexive property

Step-by-step explanation:

When a line segment is congruent or the same as itself, it is considered to have a property known as reflexive property.

This means line segment CE is a mirror image of itself. Therefore, line segment CE is congruent to line segment CE.

Line segment CE is what divides the figure given into two equal halves, making both parts congruent to each other.
