Travis goes to the book fair where paperback books are $1.50 and hardback books are $3. Travis buys five paperback books and two hardback books. How much change will Travis receive from a $20 bill?

Answers

5x1.50 = 7.5
2x3 = 6

7.5 + 6 = 13.5
Change Travis will recieve
= 20 - 13.5
= $6.5

Using the appropriate arithmetic operations, the amount of change Travis is entitled to is :$6.50

Total cost of paper back books :

($1.50 × 5) = $7.50

Total cost of hardcover books :

($3 × 2) = $6

Total cost = $7.50 + $6.00 = $13.50

Change = $20 - $13.50 = $6.50

Therefore, Travis will get a change of $6.50

Please answer quickly, I will give brainliest to whoever answers correctly, thank you.

Answers

Answer:

y = -9/8x + 7

Step-by-step explanation:

Slope-intercept form is:

y = mx + b

Points given:

(0, 7) and (8, -2)

y-intercept is

b = 7 as per the first point

And the slope is:

m = (-2 - 7)/(8 - 0) = -9/8

So the line is:

y = -9/8x + 7

Answer:

Required Answer:-

points are

(0,7)(8,-2)

slope =m

The area (A) of a rectangle is calculated as

A = width × length

let width be w then length is 2w + 3 ( 3 more than twice the width ), then

A = w(2w + 3) ← distribute

   = 2w² + 3w

When w = 4 , then

A = 2(4)² + 3(4)

   = 2(16) + 12

There is a elephant shaped weather vane at the top of a corn dryer tower that is 45 m high. If the weather vane weighs 190 N, what is the Potential Energy that the wether vane has?

Answers

Answer:

Potential Energy = 8550 Joules

Step-by-step explanation:

The potential energy of the body is the energy possessed by it due to its position therefore:

Potential energy = mgh

m = mass of the body measured in kg

g= acceleration due to gravity

h= height or distance measured in meters

But in the question asked we are not given mass but weight so

w= mg   measured in newtons

We have

w= 190 N

h= 45m

PE= mgh

PE  = w h= 190 * 45 =  8550 J

The unit of energy is Joule.

Find the quotient. 6 1/2 divided by 3 2/3

Answers

Answer:

Multiply both numbers by 10 and create a fraction. Then simplify that fraction by dividing both top and bottom by the greatest common factor.

Step-by-step explanation:

Treating 3 1/2 as 3.5 you could set up the fraction as such.

3.5 x 10 = 35

21 x 10 = 210

so you have the fraction 35/210. The GCF of the top and bottom is 35. There is one 35 in 35 and six 35s in 210

So the fraction in the simplest form is 1/6. So the quotient is 1/6.

Answer: 4, 5, 6, 7

Step-by-step explanation:

Let’s break this apart into 3 < y and y <= 7.

We can rewrite 3 < y as y > 3, and we also have that y <= 7.

This is equivalent to the verbal expression y is greater than 3 and less than or equal to 7.

We can then conclude that y must be between 4 (since that is the first number greater than 3) and 7 (since y includes 7).

Therefore, y can be 4, 5, 6, or 7!
