A 1-day movie rental at red box costs $1.39. For each additional day there is a fee of $0.50. How much will it cost to rent a movie for 7 days?

Answers

It will cost a total amount of $4.89 to rent a movie for 7 days

Word Problem

Given Data

Cost per day = $1.39

Fee per additional day = $0.50

Number of added days = 7

Let us find the mathematical expression for the above question

Total Cost = 1.39+ 0.5*7

Total cost = 1.39+ 3.5

Total cost = $4.89

Lets just simply solve:-

Days:- 1 2 3 4 5 6 7
1.39 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 = Cost to rent a movie for 7 days.

1.39 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 + 0.50 = 4.39

So, to rent a movie for 7 days it would cost $4.39.

We know that the perimeter of a triangle is the sum of its three sides.

P= 3+ (2s+4)+ (4s+2)
= (2s+ 4s)+ (3+ 4+ 2) (combine like terms)
= 6s+ 9

The perimeter is 6s+9 (units)~

(2s+4)+(4s+2)+3=6s+9. This can also be rewritten as 3(2s+3).

Write the steps for how to use a number line to multiply a 2-digit number by 20. give an example

Answers

To obtain the multiplication of $2$ digits number by $20$ first jump two times the $2$ digit number then jump $10$ times by the result we get in step 1.

Further explanation:

A straight line that has all real numbers is known as number line.

The steps involve in multiplying 2-digit number by $20$ are as follows.

1. First multiply the two digit number by 2 and the get the result.

2. Multiply the result by $10$ to obtain the final result.

For example we have to multiply $15$ by $20$ on the number line.

Following are the steps involve in multiply $15$ by $20$ on the number line.

Step 1

Multiply 15 by 2 as,

$\begin{gathered}A = 15 \cdot 2 \n= 30 \n \end{gathered}$

Make 2 jumps of 15 to get 30.

Step 2

Multiply $30$ to $10$ to obtain the final result.

$\begin{gathered}B = 30 \cdot 10 \n = 300 \n \end{gathered}$

Now make 10 jumps of 30 to get $300$ .

To obtain the multiplication of 2 digits number by $20$ first jump two times the 2 digit number then jump $10$ times by the result we get in step 1.

Keywords: two digit number, number line, twenty, multiply, add, jump, examples, multiplication.

Final answer:

To multiply a 2-digit number by 20 using a number line, draw a number line, plot your 2-digit number, make jumps of 20 units equal to your 2-digit number. The end point is the product.

Explanation:

To use a number line to multiply a 2-digit number by 20, follow these steps:

First, draw a number line. You can start at 0 and end at a number that is more than the product of your multiplication.
Plot your 2-digit number on the number line.
Start from your plotted point, and make jumps of 20 units each. The number of jumps should be equal to the quantity of your 2-digit number.
The point where you land, after making the necessary jumps, is the product of your multiplication.

For example, if you want to multiply 3 by 20: plot 3 on your number line, jump 3 points of 20 units each from point 3. You will land at 60, which is the product of 3 and 20.

we know that

The reciprocal of a number is $1$ divided by the number

Step $1$

convert the mixed number to an improper fraction

$7(1)/(3) =((7*3+1))/(3) =(22)/(3)$

Step $2$

Find the reciprocal

$(1)/((22)/(3)) =(3)/(22)$

therefore

the answer is

$(3)/(22)$
