Answer:

$48.33

Step-by-step explanation:

1. Find the amount of the sales tax by multiplying the tax percentage by the sales price.

$45 × 7.4% = $3.33

2. Add the amount of the sales tax back to the sales price.

$45.00+$3.33 = $48.33

A 60

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

there are 2 ways to solve this...

1st, y=60 by the vertical angles theorem

2nd, x=120 by the linear pair postulate (x + 60 = 180)

next, y=60 because y + 120 = 180

Gravitational potential energy = mgh = (80)(9.81)(100) = 78,480J.

Answer:

The answer is below

Step-by-step explanation:

A student on the cross- county team runs 30 minutes a day as a part of her training. Write an equation to describe the relationship between the distance she runs in miles, D, and her running speed, in miles per hour, when she runs at a constant speed of 5.4miles per hour for m minutes, and then at b miles per hour for n minutes

Solution:

Given that the student runs for a total of 30 minutes per day. He runs at 5.4 miles per hour for m minutes, and then at b miles per hour for n minutes.

Hence:

m + n = 30

60 minute = 1 hour. Therefore, m minute = m/60 hour, n minute = n/60 hour.

The distance traveled is the product the speed in miles per hour and the time taken to cover the distance. Distance = speed * time

The total distance ran (D) is:

D = 5.4(m/60) + b(n/60)

Answer:

23.75

Step-by-step explanation:

Given that:

Brian's age = 27

Age of Chris is 17 more than one - fourth of Brian's age.

To find:

Age of Chris = ?

Solution:

Let age of Chris = [tex]x[/tex]

One - fourth of Brian's age =  [tex]\frac{27}{4}[/tex]

17 more than One - fourth of Brian's age = [tex]\frac{27}{4}[/tex] + 17

Therefore, we can write the equation as per question statement:

[tex]x = \frac{27}{4} + 17\\\Rightarrow x = 6.75+17\\\Rightarrow \bold{x = 23.75}[/tex]

Therefore, Chris is 23.75 years old if Brian is 27.

Answer:

15 and 21

Step-by-step explanation:

Answer:

15 and 21

Step-by-step explanation:

Answer:

a. i. 1.11 h ii. 1 h. b. Liam

Step-by-step explanation:

a.

i. Sam's time

We know distance d = vt where v = speed and t = time.

Since our distance here is the length of the path, d = 1 mile.

For Sam, his speed up the hill is v = 1 mph, so, the time it takes him to go uphill is t = d/v = 1 mi/1 mph = 1 h.

He goes down hill at a speed of v = 9 mph, so the time it takes him to go down hill is t = d/v = 1 mi/9 mph = 1/9 h = 0.11 h

So, the total time it takes him to complete the trip is t = 1 h + 0.11 h = 1.11 h

ii. Liam's time

For Liam, his speed both uphill and downhill is v = 2 mph, so, the time it takes to cover each trip is t = d/v = 1 mi/2 mph = 0.5 h.

So for both uphill and downhill trip, the total time is t' = 2 × 0.5 h = 1 h

b. Since Liam's time t' = 1 h < Sam's time t = 1.11 h, that is t' = 1h < t = 1.11 h, Liam is the winner.

Answer:

D

Step-by-step explanation:

The answer is D on Edge 2020

The missing step in the table is  sin(2x) = sin(x)cos(x) + sin(x)cos(x), the correct option is D.

Trigonometric Ratios are ratios of the side of a right angled triangle. These are used to find the missing sides and angles of a right angled triangle.

The step 1 in the table is

sin (2x) = sin (x+x)

The step 3 is

sin (2x) = 2 sine (x) cosine (x)

The step 2 is obtained by the trigonometric identity

sin (x+y) = sinx cosy + cosx siny

So,

sin (x+x) = sinxcosx+sinx cosx

sin (2x) =  sin(x)cos(x) + sin(x)cos(x)

Given:

The zeros of the polynomial are [tex]-2,\pm 5,4[/tex].

Degree = 4

Leading coefficient  = 1

To find:

The polynomial.

Solution:

If c is a zero of a polynomial, then (x-c) must be a factor of the polynomial.

Here, -2,4,-5, 5, are zeros of the required polynomial, so (x+2), (x-4), (x+5), (x-5) are factors of required polynomial.

[tex]p(x)=(x+2)(x-4)(x+5)(x-5)[/tex]

[tex]p(x)=(x^2-4x+2x-8)(x^2-5^2)[/tex]     [tex][\because a^2-b^2=(a-b)(a+b)][/tex]

[tex]p(x)=(x^2-2x-8)(x^2-25)[/tex]

Using distributive property, we get

[tex]p(x)=x^2(x^2-25)-2x(x^2-25)-8(x^2-25)[/tex]

[tex]p(x)=x^4-25x^2-2x^3+50x-8x^2+200[/tex]

On combining like terms, we get

[tex]p(x)=x^4-2x^3+(-25x^2-8x^2)+50x+200[/tex]

[tex]p(x)=x^4-2x^3-33x^2+50x+200[/tex]

Here, the leading coefficient is 1. So, it is the required polynomial.

Therefore, the correct option is E.

Answer:

Step-by-step explanation:

The required graph of the given function d(x)=−1/2x−3 has been shown.

Given that, to plot the graph of the linear function,  d(x)=−1/2x−3.

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
The graph of the liner function d(x)=−1/2x−3 can be plot by putting the values of the x in the equation which gives the value of y by calculating such an ordered pair we can plot the curve of the liner equation on the graph. i.e.
At x = 0
d(0) = -1/2 * (0) - 3
d(0) = -3
So, the ordered pair will be (0, -3).
Now, put x = 2
d(2) = -1/2 * 2 - 3
d(2) = -1 - 3
d(2) = - 4
So the ordered pair will be (2, -4)
joining these two points will show the graph of the given equation d(x)=−1/2x−3.

Thus, the required graph of the given function d(x)=−1/2x−3 has been shown.
