don't know what to do. What is the slope of the roof?

Answers

Answer 1

The slope of a line is given by the formula,

Slope = change in y over change in x.

Better still,

$\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \text{This can also be written as,} \\ m=\frac{\Delta y}{\Delta x} \\ \text{Where }\Delta\text{ represents the change in the variables y and x} \\ m=\frac{17-8}{12} \\ m=\frac{9}{12} \\ m=\frac{3}{4} \\ OR \\ m=0.75 \end{gathered}$

Please note that on the y axis, the change is from 8 to 17, while on the x axis, the change between both points has already been marked as 12

Scott is four more than double the age of Todd. Scott is 56. What is Todd's age?

Answers

Answer: 26 years old

Step-by-step explanation:

Since Scott is four more than double the age of Todd, start by taking away four from Scott's age.

56-4=52

Then take half of that because that would be double of Todd's age

52/2=26

Todd is 26 years old.

A circular kiddie pool has an area of about 28 square feet. An inflatable full-size circular pool has an area of about 113 square feet. How much greater

Answers

The radius of the full-sized pool is 2 times larger than the radius of the kiddie pool.

By using the expression to approximate the radius of a circle, we want to compare the radius of the two pools.

The expression for the radius of a circle is:

R = √(A/3)

Where A is the area of said circle.

The circular kiddie swimming pool has an area of 28ft^2, we just replace that in the above expression to get:

R = √(28 ft^2/3) = 3 ft

The full-sized pool has an area of 113 ft^2, then its radius is:

R' = √(113 ft^2/3) = 6 ft

To see how much greater is the radius of the full-sized pool than the radius of the kiddie pool, we just take the quotient:

R'/R = 6ft/3ft

= 2

Hence, the radius of the full-sized pool is 2 times larger than the radius of the kiddie pool.

Ana works 25 hours a week at the library. If she is paid $10 an hour, and her net salary each week is $212.50, what percent of her salary is withheld for taxes?

Answers

Approximately 17.65% of Ana's salary is withheld for taxes.

To calculate the percentage of Ana's salary that is withheld for taxes, we need to determine the amount of tax withheld and then express it as a percentage of her net salary.

Number of hours worked per week (H) = 25 hours

Hourly wage (W) = $10

Net salary (S) = $212.50

Calculate the total earnings before taxes:

Total earnings = Hours worked * Hourly wage

Total earnings = 25 hours * $10/hour

Total earnings = $250

Determine the amount of tax withheld:

Tax withheld = Total earnings - Net salary

Tax withheld = $250 - $212.50

Tax withheld = $37.50

Calculate the percentage of salary withheld for taxes:

Percentage withheld = (Tax withheld / Net salary) * 100

Percentage withheld = ($37.50 / $212.50) * 100

Percentage withheld ≈ 17.65%

Therefore, approximately 17.65% of Ana's salary is withheld for taxes.

To completely solve the problem, Karim should convert the product back into standard decimal notation.

We cannot directly apply the product of powers property because the binomial is not raised to a power itself.

Miscellaneous problem

(1) To convert a number from scientific notation to standard decimal notation, we multiply the coefficient (0.0258) by 10 raised to the power of the exponent (-8).

0.0258 × $10^{-8$ = 0.0258 × 0.00000001

= 0.000000000000258

(2) The product of powers property states that when you raise a term with an exponent to another exponent, you can simplify it by multiplying the exponents.

In the expression $(3z + y)^3$, we have a binomial term (3z + y) raised to the power of 3. This is not a situation where we can directly apply the product of powers property because the binomial is not raised to a power itself.

To simplify the expression, we need to expand it using the binomial theorem or by applying the concept of binomial expansion.

Since it's compounded annually, and no time needs to be converted, we can use the formula $y=Pe^r^t$, where P is the starting amount, e is Euler's number, r is the rate in decimals, and t is time. The first task would be to find the t. The question set us a timeframe of 2 to 18, so 18-2=16, therefore our t is 16. Plugin the known into the formula and calculate:

FIND EACH LENGHT BELOW ITS AN ALEX ASSIGNMENT UNDER THE CATEGORY SEGMENTS IN CIRCLES

Answers

The length in each circle is:

(a) CD = 19.5 units

(b) UZ = 12.8 units

How to find the length in each circle?

(a) The Intersecting Secant-Tangent Theorem states that "if two secant lines intersect outside a circle, and a tangent line is drawn from the point of intersection to the circle, then the product of the lengths of the two secant segments is equal to the square of the length of the tangent segment".

Using the theorem, we have:

EC * ED = EG²

6.5 * ED = 13²

6.5ED = 169

ED = 169/6.5

ED = 26 units

ED = EC + CD

26 = 6.5 + CD

CD = 26 - 6.5

CD = 19.5 units

(b) The Secant-Secant Theorem states that "if two secant segments which share an endpoint outside of the circle, the product of one secant segment and its external segment is equal to the product of the other secant segment and its external segment".

Using the theorem above, we can say:

UZ * UW = UX * UY

UZ * 40 = 8 * 64

40UZ = 512

UZ = 512/40

UZ = 12.8 units

Malcolm has $50 gift card to a local car wash and order is the ultimate car wash each visit is $8.95

Answers

The amount cheaper is the car washes Malcolm orders than the car washes Martha's order is $13.

The correct answer choice is option B.

How much cheaper is the car washes Malcolm orders than the car washes Martha's order?

Malcolm's gift card = $50.

Cost Malcolm's car wash per visit = $7

Martha's gift card = $180

Cost Martha's car wash per visit = Difference between gift card balance of first and second visit

= $180 - $160

= $20

How cheap is the car washes Malcolm orders than the car washes Martha's order = $20 - $7

Eight upright dominos of increasing height are lined up to be knocked down. The dominos are numbered 0 to 7. The smallest domino, #0, is 4.00 cm tall and will be toppled by a person to start the chain reaction. Each subsequent domino is 12% taller than the one before. What is the height of domino #7?

Answers

The height of domino #7 is approximately 6.89 cm tall.

How to solve for the height

The formula for the nth term of a geometric progression is:

$a_n = a * r^(^n^-^1^)$

where:

a is the first term (the height of the smallest domino, 4.00 cm),

r is the common ratio (the growth rate, 1.12), and

n is the term number (for domino #7, n = 7 + 1 = 8, because the sequence starts with domino #0).

Let's plug these values into the formula:

$a_8 = 4.00 cm * (1.12)^7$

(Note that we're using 7, not 8, because the first domino is #0, not #1.)

Now, compute the value:

$a_8 = 4.00 cm * (1.12)^7$

= 6.89 cm

So, domino #7 is approximately 6.89 cm tall.

Profit can be modeled by the polynomial expression
If 1,000 video game systems are sold, the company's profit is S

Answers

Answer:

Expression that represents the profit is 3x - 180.

The company's profit is $2,820

Step-by-step explanation:

The profit, in dollars, can be found by subtracting the cost from the revenue:

Profit = Revenue - Cost

Profit = (5x² + 2x - 80) - (5x² - x + 100)

Simplifying the expression by distributing the negative sign:

Profit = 5x² + 2x - 80 - 5x² + x - 100

Combining like terms:

Profit = 3x - 180

Therefore, the expression that represents the profit is 3x - 180.

To find the profit when 1,000 video game systems are sold, we can substitute x = 1000 into the expression:

Profit = 3x - 180

Profit = 3(1000) - 180

Profit = 2,820

So if 1,000 video game systems are sold, the company's profit is $2,820.
