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

the line goes up 11, and over 5, therfore the slope would be rise over run...so 11/5

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

Answer:

There are 3 or more steps to dividing fractions

Step-by-step explanation:

1. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator)

2.Next, multiply the two numerators

3.Then, multiply the two denominators.

4.Finally, simplify the fractions if needed

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.

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

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

d = 16

Answer:

-457.96

Step-by-step explanation:

Step-by-step explanation:

273.15 + °C = K

°C = K - 273.15

0.95K to °C = 0.95 - 273.15 = -272.2°C

°C to °F

(9/5 °C) + 32 = °F

(9/5 × -272.2) + 32 = °F

-489.96 + 32 = °F

= -457.96°F

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

Answer:

Its either x=17 or x=19

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.

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:

Considering the diagram attached below, we are given that:

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

Applying the Pythagorean theorem:

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

XW = XZ + WZ

XZ = 12 (given)

WZ = TW = 3 (congruent segments)

XW = 12 + 3

XW = 15

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

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

Answer:

Molly had a greater ratio.

Step-by-step explanation:

If I were to multiply Molly's ratio by two it would give us 10:8 which is now comparable to 10:7 and 10:8 is greater than 10:7, therefore, Molly had the greater ratio. Hope this helps! Have a great day!

Answer:

B

Step-by-step explanation:

Took the quiz

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
