What is the value of n in the equation in = 9?
n =

Answer:

The answer is 108mi

Step-by-step explanation:

to solve this problem, we need to write a ratio.

[tex]\frac{468mi}{13hrs}[/tex]

to solve for 3 hours, we need to figure out how many miles the bird can fly in 1 hour. to do that, we need to divide the numerator and denominator by 13.

[tex]\frac{36mi}{1hr}[/tex]

now we have a unit rate that represents distance covered per hour.

to solve for 3, we need to multiply the numerator and denominator by 3.

[tex]\frac{108mi}{3hrs}[/tex]

the question is asking for miles. therefore, the bird can fly 108mi in 3 hrs.

hope this helps!

Answer:

108 miles

Step-by-step explanation:

For this problem you can create a proportion:

[tex]\frac{468 miles}{13 hours}[/tex]

To find how many miles it flies in 3 hours, we need to find the unit fraction. Do this by making the denominator (bottom number) 1:

here, we must divide by 13:

[tex]\frac{468 miles}{13 hours}[/tex]÷[tex]\frac{13}{13}[/tex]= [tex]\frac{36 miles}{1 hour}[/tex]

Each hour, they fly 36 miles.

To find how many miles they fly in 3 hours, make a proportion:

[tex]\frac{36 miles}{1 hour}[/tex]=[tex]\frac{x miles}{3 hours}[/tex]

Then, solve:

use cross multiplication:

36·3=108

x·1=x

108=x

The cost of each message is $0.015.

Option C graph best approximates Jerry's text message plan.

Given,

On Jerry's text message phone plan, she paid $0.30 for every 20 messages she sent.

We need to find what is the cost per message in dollars.

We divide the total cost by the number of items.

Example: 10 pieces cost $20

1 pieces cost = $20/10 = $2

We have,

$0.30 for every 20 messages.

The cost of each message:

= $0.30/20

= $0.300

= $0.015

We can see that in the graph x-axis represents the number of messages and the y-axis represents the cost of each message.

We have,

$0.30 = 20 messages

3 x $0.30 = 3 x 20 messages

$0.90 = 60 messages.

We need a graph that has a point that intersects $0.90 and 60 messages.

We see that in the graph of Option C.

Option C graph best approximates Jerry's text message plan.

Thus,

The cost of each message is $0.015.

Option C graph best approximates Jerry's text message plan.

Answer:

(x+1)+(3x+1)+(2x+4)=180 (sum od all sode of a triangle is 180)

x+1+3x+1+2x+4=180

6x+6=180

6x=180-6

x=174/6

x=66

Answer:

x = 4

Step-by-step explanation:

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

(3x + 1)² = (x + 1)² + (2x + 4)² ← expand all factors using FOIL

9x² + 6x + 1 = x² + 2x + 1 + 4x² + 16x + 16 , simplify right side

9x² + 6x + 1 = 5x² + 18x + 17 ( subtract 5x² + 18x + 17 from both sides )

4x² - 12x - 16 = 0 ( divide through by 4 )

x² - 3x - 4 = 0 ← in standard form

(x - 4)(x + 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x + 1 = 0 ⇒ x = - 1

However, x > 0 thus x = 4

Answer:

All non zero digits count in significant digits.

(a) is correct option.

Step-by-step explanation:

Given that,

1.4 has 2 significant digits.

We know that,

Significant digits :

All non zero digits count in significant digits.

All zero which is present in between two significant digits it is also significant.

Leading zero is not count as significant.

Trailing zero is count as significant.

We need to find 1.4 has 2 significant digits as a result of which rule

Using given rules

1.4 has 2 significant digits it is follows the rule of all non zero digits count in significant digits.

Hence, All non zero digits count in significant digits.

(a) is correct option.

Alisa hopes to play beach volleyball in the Olympics someday. She has convinced her parents to allow her

to set up a beach volleyball court in their back yard. A standard beach volleyball court is approximately

26 feet by 52 feet. She figures that she will need the sand to be one foot deep. She goes to the hardware store to shop for sand and sees the following signs on pallets containing bags of sand.

Sand A = 60Ibs = $5

Sand B = 150lbs = $12

Alisa uses her cell phone to search how many pounds of sand is required to fill 1 cubic foot and finds the answer is 100 pounds. Choose one of the brands and compute how much it will cost Alisa to purchase enough sand to fill the court. Identify which brand was chosen as part of your answer.. Answer:

For Sand A should would need:

$11.266.67

Step-by-step explanation:

From the above question, we can assume that: her court is 1 cubic foot and can be filled with 100 pounds of sand

First we find the volume of the box

52ft × 26ft × 1 ft

= 1352 ft³

100Ib = 1 ft³

1352 ft³ × 100 Ib/ft³

= 135200Ibs

Sand A = 60Ibs = $5

Hence, $1 = 60Ibs/5

= 12Ibs

To purchase enough sand using Sand A to fill the court

= 135200Ibs/12lbs

= $11.266.67

Each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses

Step-by-step explanation:

Let x denotes number of boxes to be sold by each scholar to raise enough money to cover the team's travel expenses.

Number of scholars = 7

Total number of boxes [tex]=7x[/tex]

Total number of chocolate bars [tex]=(7x)(30)=210x[/tex]

Price of 1 chocolate bar = $2

Price of [tex]210x[/tex] chocolate bars [tex]=210x(2)=\$420x[/tex]

Also,

Total amount to be raised for travel expenses = $1680

So,

[tex]1680=420x\\x=\frac{1680}{420}\\ x=4[/tex]

Therefore,

each scholar have to sell 4 boxes in order to raise enough money to cover the team's travel expenses

$1,050*125x=P(x). I just need more characters.

Step-by-step explanation:

The equation that represents Arnold's total monthly paycheck is

P(x) = 125x + 1050.

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, Each month, Arnold receives $1,050 for working part-time at his uncle's camera store so it is a constant income.

For each camera that he sells, he earns a $125 bonus.

Let P(x) be the monthly check and no. of cameras sold be x.

∴  Arnold's total monthly paycheck P(x) selling x cameras is,

P(x) = 125x + 1050.
