Answer:

Buyer's real estate agent's commission rate = 4%

Seller's real estate agent's commission rate = 2.5%

Step-by-step explanation:

Given that:

Amount for which the house was sold = $275,100.00

Earnings by buyer's Real Estate Agent = $11004.00

Earnings by seller's Real Estate Agent = $6,877.50

To find:

The commission rate of each agent = ?

Solution:

Commission rate can be calculated by finding the percentage for both the real estate agents with the amount for which the house was sold.

i.e.

[tex]\text{Rate of Buyer's agent } = \dfrac{\text{Earnings of Buyer's agent}}{\text{Amount for which the house was sold}}[/tex]

[tex]\Rightarrow \dfrac{\$11004.00}{\$275,100.00}\times 100 = 4\%[/tex]

[tex]\text{Rate of Seller's agent } = \dfrac{\text{Earnings of Seller's agent}}{\text{Amount for which the house was sold}}[/tex]

[tex]\Rightarrow \dfrac{\$6,877.50}{\$275,100.00}\times 100 = 2.5\%[/tex]

Therefore, the answer is:

Buyer's real estate agent's commission rate = 4%

Seller's real estate agent's commission rate = 2.5%

C = 6 + [tex]12^{x}[/tex]

The required function to model the cost is given as c = 6h + 12h.

Given that,
A surf shop charges $6 to rent a wetsuit and $12 per hour to rent a surfboard. To write a function to model the cost, c, to rent a wetsuit and surfboard for h hours.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

here,
According to the question,
Rent on a wetsuit for h hours = 6h
Rent on a surfboard for h hours = 12h
Total rent, c = 6h + 12h

Thus, the required function to model the cost is given as c = 6h + 12h.

zeros at 4 and 0 are the roots so can be factor as x*(x-4) and the multiplicity tels to what power you have to raise those factors

[tex]x^{1} *(x-4)^{3}[/tex] becuase multiplicity of 1 for root at 0, and multiplicity of 3 at root 4

216 miles

Step-by-step

ex15.95+.73x=173.63

.73x=173.63-15.95

.73x=157.68

x=157.68/.73

x=216 miles driven.

PROOF;

15.95+.73*216=173.63

15.95+157.68=173.63

173.63=173.63

Answer: Keith drove the truck for 123 miles

Step-by-step explanation:

17.99+0.97m=137.30

Subtract 17.99 on both sides:

17.99-17.99+0.97m=137.30-17.99

0.97m=119.31

Divide 0.97 on both sides:

0.97m/0.97=119.31/0.97

m=123 miles

Answer:

profit will be maximized by making 20 doodles and 20 paintings = ($10 x 20) + ($20 x 20) = $600

Step-by-step explanation:

we have to maximize the following equation:

$10P + $20D

where:

P = number of portraits

D = number of doodles

the constraints are:

P + D ≤ 40

P ≤ 30

D ≤ 20

we do not need to use solver or any other type of linear programming tool to solve this, since profit will be maximized by making 20 doodles and 20 paintings = ($10 x 20) + ($20 x 20) = $600

Alejandro is correct because the 20 falls between 4 and 5 and the decimal terminates. Option B is correct.

Given that,
Frankie argues that the fraction 20 is a rational number because the square root of 20 is 10. Frankie believes that because 10 is a whole number, it is rational. Alejandro disagrees. He believes that 20 is a rational number because the square root falls between 4 and 5, and the decimal terminates.

Rational numbers are numbers that can be structured in the form of the fraction of integers. Eg- 5/6, 2/3 etc.

Here,
20 is a rational number but its square root is not 10 so, Frankie is not correct.
The square root of 20 falls between 4 and 5 the decimal terminates. its true and Alejandro is correct.

Thus, Alejandro is correct because the 20 falls between 4 and 5 and the decimal terminates. Option B is correct.

Answer:

[tex] y = -\frac{4}{3}x + 9 [/tex]

Step-by-step explanation:

The equation that represents the path of the swimmer to the shoreline can be represented in the slope-intercept form, given as [tex] y = mx + b [/tex].

Where,

Slope (m) = the negative reciprocal of the slope of the shoreline, since it is perpendicular to it = ??

y-intercept (b) = ??

Find the slope of the shoreline using, (0, 1) and (4, 4):

[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 - 1}{4 - 0} = \frac{3}{4} [/tex].

Since the slope of the shoreline is ¾. The slope of the path of the swimmer would be the negative reciprocal of ¾.

The negative reciprocal of ¾ = -⁴/3.

The slope of the swimmer's path = -⁴/3.

Using the coordinate of the point of the swimmer (6, 1), and the slope of the path, we can find b, the y-intercept of the path.

Substitute x = 6, y = 1 and m = -⁴/3 into y = mx + b, to find b.

Thus:

1 = (-⁴/3)(6) + b

1 = -8 + b

Add 8 to both sides

1 + 8 = b

9 = b

b = 9

Substitute m = -⁴/3 and b = 9 into y = mx + b.

✅The equation that represents the path would be:

[tex] y = -\frac{4}{3}x + 9 [/tex]

Answer:

3 solutions

Step-by-step explanation:

To solve g(x) = 2

The solutions are at the points of intersection of g(x) and y = 2

y = 2 is the equation of a horizontal line parallel to the x- axis and passing through all points with a y- coordinate of 2

If you draw the horizontal line using say (0, 2) and (2, 2)

Then g(x) intersects y = 2 at 3 places

Thus there are 3 solutions to g(x) = 2

Step-by-step explanation:

Bowls of Punch = 6

Each bowl holds 2 1/2 gallons of punch

6 bowls = 2 1/2 gallons × 6

= 5/2 × 6 gallons

= 30/2

= 15 gallons

6 bowls of Punch = 15 gallons of Punch

1 gallon = 4 quarts

15 gallons = 4 × 15 quarts

= 60 quarts

6 bowls of Punch = 15 gallons of Punch = 60 quarts of punch

She thinks each person will drink about 1 quart of punch.

How many people will the 6 bowls of punch serve?

6 bowls of Punch = 15 gallons of Punch = 60 quarts of punch

60 quarts of punch / 1 person

= 60 people

The 6 bowls of punch will serve 60 people
