The length of a rectangle is 3 more than the width. The
perimeter of the rectangle is 72 in.
What is the length of the rectangle?
Answer ASAP for brainly

Answers

Answer:

19.5 in.

Step-by-step explanation:

Let the width = x.

The length is 3 more than the width, so the length is x + 3.

perimeter = 2 * length + 2 * width

perimeter = 2(x + 3) + 2x

perimeter = 72

2(x + 3) + 2x = 72

2x + 6 + 2x = 72

4x + 6 = 72

4x = 66

x = 16.5

x + 3 = 16.5 + 3 = 19.5

Answer: 19.5 in.

Midland Electronics is advertising that everything in their store is 10% off. If p represents the origin

their store, then the sale price of the item can be represented by the expression p-01p.

A

Write an equivalent expression to represent the sale price of the item.

B. Using complete sentences, describe how the sale price can be found in two different ways.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Sales discount = 10%

If original price of items = p

Hence, the sales price of the item can be represented as :

(100% - percentage discount) * sales price

(100% - 10%) * p

90% * p

0.9p

B.)

(1) By subtracting the offered percentage discount (10%) from the full percentage cost (100%) and then multiplying the result by the original cost of the item.

(11.) by obtaining discount amount (10% of the original price) , and then subtracting the discounted amount from the original price of the item.

Answers

Answer:

Let me try...

Step-by-step explanation:

let's combine like terms first to simplify the equation

we need to only combine the variables with the same variable.

3a+5a would make 8a

and 4b+10b would be 14b

but we cannot combine 8a and 14b

so the equation remains as 8a+14b

Ice cream costs $1.99 per container. At a tax rate of 4.75%, estimate the final cost of the
ice cream.

Answers

Answer:

The final cost of ice-cream container is: 2.09 dollars

Step-by-step explanation:

In order to find the price of an item after adding tax the tax is found on the price of the item and then added to the cost.

Given

Price of ice cream container = $1.99

Tax Rate = 4.75%

The amount of tax t will be:

[tex]t = 4.75\%\ of\ 1.99\\= 0.0475*1.99\\=0.094525[/tex]

Rounding off to nearest hundredth

t = 0.10

The final cost is given by:

[tex]Final\ cost = Cost + tax\\= 1.99+0.10\\=2.09[/tex]

Hence,

The final cost of ice-cream container is: 2.09 dollars

You have saved $40 for a video game and your parents will contribute some money. They said they will give you $1 for every $4 you save. How much have they contributed

Answers

Answer:

They contributed $8

Step-by-step explanation:

Given

[tex]Savings = \$40[/tex]

Proportion of savings: [tex]Parent = \$1[/tex]   [tex]You = \$4[/tex]

Required

Determine your parent contribution

From the question, we understand that, they contribute $1 when you save $1.

This means that the unit savings is:

[tex]Unit = \$4 + \$1[/tex]

[tex]Unit = \$5[/tex]

The parent contribution is then calculated as:

[tex]\frac{Parent\ Proportion}{Unit\ Savings} * Total\ Savings[/tex]

[tex]= \frac{\$1}{\$5} * \$40[/tex]

[tex]= \frac{1}{5} * \$40[/tex]

[tex]= \frac{1* \$40}{5}[/tex]

[tex]= \frac{\$40}{5}[/tex]

[tex]= \$8[/tex]

Hence, they have contributed $8

We can rewrite the polynomial as follows;

x^2 + 6x + 9 + 4

We can factorize the first part;

x^2 + 3x + 3x + 9 + 4

x(x + 3)+ 3(x + 3) + 4

How many turns will the graph of f(x) = 3x5 -2x4 + 7x2 -9x + 8 have?

Answers

Answer:

The number of turns of graph for [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] are 4

Step-by-step explanation:

We need to find the number of turns the graph of [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] have?

Turns of graph:

The graphs turns when it changes from increasing to decreasing (rise to fall) or decreasing from increasing (fall to rise)

Turns of graph for a polynomial

A polynomial having degree n will have maximum n-1 turns.

So, for the given polynomial

[tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex]

We need to find degree

The highest exponent of the polynomial is the degree of polynomial

So, Degree n = 5

Number of turns = n - 1 = 5-1 =4

So, the number of turns of graph for [tex]f(x) = 3x^5 -2x^4 + 7x^2 -9x + 8[/tex] are 4

y = -2x + 7 and y = 3x – 8

Insurance company executives surveyed 200 young adults about their first motor vehicle. The results of the survey are given in the following two-way table.

A survey participant is randomly selected. Let F be the event that the participant’s first motor vehicle had four cylinders and let C be the event that the participant’s first motor vehicle was a car. What is the value of P(F or C)?

A) 0.59
B) 0.68
C) 0.71
D) 0.80

Answers

Answer:

C) 0.71.

Step-by-step explanation:

To find the probability of an event occurring, we need to sum up all the probabilities of the outcomes that satisfy the event. In this case, the event "F or C" is satisfied by all the outcomes in which the participant's first motor vehicle had four cylinders or was a car.

We can see from the table that 118 out of the 200 participants had their first motor vehicle as a car, so the probability of this event occurring is 118/200 = 0.59. Similarly, we can see that the probability of the event "first motor vehicle had four cylinders" occurring is (118 + 4) / 200 = 0.62.

Therefore, the probability of the event "F or C" occurring is the sum of the probabilities of these two events occurring, which is 0.59 + 0.62 = 0.71. The correct answer is therefore C) 0.71.

The value of the probability P(F or C) is 0.80, Option D is correct.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

Given that a survey participant is randomly selected.

Let F be the event that the participant’s first motor vehicle had four cylinders and

let C be the event that the participant’s first motor vehicle was a car.

We need to find the value of P(F or C)

The number of P or c is 118+6+18+16+2

=160

The number of people in total are 200.

P(F or C )= 160/200

=0.80

Hence, the value of the probability P(F or C) is 0.80, Option D is correct.
