The camping trip costs $165. How long will it take you to save enough money?

25 Points I guess.

Answers

Answer:

11 weeks

Step-by-step explanation:

$165 / 15 = 11 weeks

11 weeks

Hope that helps!

The equation of line is given by y = 15x and the number of weeks to save enough money is 11 weeks

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the number of weeks be x

Let the cost of trip be y

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P ( 4 , 60 )

Let the second point be Q ( 8 , 120 )

Now , the slope of the line between the two points is

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 120 - 60 ) / ( 8 - 4 )

On simplifying the equation , we get

Slope m = 60 / 4

Slope m = 15

Now , the equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 60 = 15 ( x - 4 )

On simplifying the equation , we get

y - 60 = 15x - 60

Adding 60 on both sides of the equation , we get

y = 15x

Now , the cost of the camping trip is $ 165

Substitute the value of y = 165 , we get

165 = 15x

Divide by 15 on both sides of the equation , we get

x = 165/15

x = 11 weeks

Therefore , the value of x is 11 weeks

Hence , the equation is y = 15x

What is the sum of 4 and its additive inverse?

Answers

Definition of Additive Inverse
If y is the additive inverse of x, then y = -x or vice versa. For example, the additive inverse of the positive number 4 is -4. That's because their sum is zero, or 4 + (-4) = 0. So, Additive Inverse of a number is the negative of that number.

The additive inverse is the opposite sign quantity so the sum of 4 and its additive inverse will be 0.

What is summation?

A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation.

Given the number 4.

The sign of the number 4 is positive.

An additive inverse is a number whose sign is opposite to the number.

For example, the additive inverse of -5 is 5, and 5 is -5.

So additive inverse of 4 will be -4.

Now sum of 4 and -4

4 + (-4) = 0

Hence "The additive inverse is the opposite sign quantity so the sum of 4 and its additive inverse will be 0".

Jane and 3 friends decided to split the cost of a pizza evenly. The total cost was $25.48. How much does each friend have to pay?​

Answers

Answer:

$6.37

Step-by-step explanation:

Jane and 3 friends = Jane + another 3 people

= 4 people in total

Total Cost of pizza = $25.48

If 4 people split $25.48 evenly,

Amount each friend has to pay = Total Cost of pizza/Total number of people

= $25.48/4

= $6.37 per friend

Each friend has to pay $6.37 each if $25.48 is splitted evenly amongst them

Step-by-step explanation:

A man invests 10000 for 3 years at a certain rate of interest, compounded annually. At the
end of one year, it amounts to 11200. Calculate :
(i) the rate of interest per annum;
(ii) the interest accrued in the second year;
(ii) the amount at the end of the third year.​

Answers

Step-by-step explanation:

10000, After 1 year amount = 11200 so interest after 1 year = 1200

Amount = P(1+R/100)T

11200 = 10000(1+R/100)1

R = 12%

Interest for the second year = 11200(1+12/100)1 - 11200 = 1344

after 3 years = 10000(1+12/100)3 = 14049.28

Step-by-step explanation:

(I) Principle = Rs 10000, After 1 year amount

= Rs 11200 so interest after 1 year

= Rs 1200

R = 12%

Amount = P(1+R/100)T

11200 = 10000(1+R/100)1

R = 12%——————————————————————————————————————

(Ii)Interest for second year = 11200(1+12/100)1 - 11200 = Rs 1344

(iii)Amount after 3 year = 10000(1+12/100)3 = Rs 14049.28

An electrician bought 120 feet of electrical wire and used 105 feet of it
What percent of the wire went unused?
A 15%
B 12.5%
C 8.75%
D 7%

Answers

Answer:

B. 12.5%

Step-by-step explanation:

Find how much was unused:

120 - 105

= 15

To find what percent this is, divide it by 120:

15/120

= 0.125

Multiply this by 100:

0.125(100)

= 12.5

So, 12.5% of the wire went unused

The correct answer is B. 12.5%
