Answer:

$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.

Answer:

Omg this is the third time i answered this question, The United States is 387.87 times larger than Columbus, Ohio.

Step-by-step explanation:

8.25 times 100000 = 825,000

3.2 times 100000000 = 320,000,000

320,000,000 divided by 825,000 = 387.87

Answer:

It is 7

Step-by-step explanation:

y = mx+b

y is the total cost.

x is the number of hours.

b : that's 16 dollars.

y = 9x+16

The problem states that the cost was 79 dollars.

Substitute that for y and solve for x.

79 = 9x+16

63 = 9x

x = 7 hours

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

Given parameters:

Number of sides of the regular body  = 10

Sum of the measures of the interior angles = ?

Solution;

 To find the sum of the interior angles of a decagon; use the expression below:

             Sum of interior angles  =  (n - 2) x 180

where;

  n = number of sides;

So,

         Sum of interior angles  = (10 - 2) x 180 = 1440°

The sum of interior angle of a decagon is 1440°

Answer:

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

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.

Answer:

Step-by-step explanation:

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:

B=-1

Step-by-step explanation:

Standard form is Ax+By=C.

In this case, Ax is x, By is 1/5y, and C is +2.

To isolate the 2 (the C), subtract x from both sides of the equation:

x+2=1/5y

-x     -x

2=-x+1/5y.

Now, the value of B, the x value, is -1.
