Geet sells televisions. He earns a fixed amount for each television and an additional $15 if the buyer gets an extended warranty. If Geet sells 13 televisions with extended warranties, he earns $845. How much is the fixed amount Geet earns for each television?
The fixed amount Geet earns for each television he sells is $ .
Answer: The fixed amount Geet earns for each television is $60.
Step-by-step explanation: Geet sells televisions. He earns a fixed amount for each television and an additional $ 30 if the buyer gets an extended warranty. If Geet sells 17 televisions with extended warranties, he earns $ 1,530.Now, to find the fixed amount Geet earns for each television.Let the cost of fixed amount be .Number of television = 17.He earns total = $1,530.He earns additional amount = $30.Now, to get the fixed amount we put an equation: Subtracting both sides by 510 we get:Dividing both sides by 17 we get:Therefore, the fixed amount Geet earns for each television is $60.
Answer:
$15 Fixed Amount Per TV
Step-by-step explanation:
13 x 15 = 195 - Extended Warranty
845 - 195 = 650
650 ÷ 13 = 50 - Fixed Amount

What is an exponential function?An exponential function is a relation of the form y = a^x, with the independent variable x ranging over the entire real number line as the exponent of a positive number a.
The y-value at -4 is 16 while the y-value at -1 is 2, a decrement of 1/8 times for an increment in x-value by 3
Again, the y-value at 2 is 0.25 while the y-value at 5 is 0.03125, a decrement of 1/8 times for an increment in x-value by 3.
In both cases, the rate of decrement is constant.
So we can say that this is an example of constant exponential decay.
We can also see this behavior from the attached graph.
Therefore, the given table is an example of constant exponential decay.

Please help me please please please
Step-by-step explanation:
Given :-A triangle have two angles that measures 85° and 23°.To Find :-Measure of the third angle.Solution :-Let the measure of the third angle of the triangle be x.
As we know that,
The sum of all three sides of a triangle is 180° which is the angle sum property of triangle.Therefore,
[tex] \sf \longrightarrow {\angle{A}\ +\ \angle{B}\ +\ \angle{C}\ =\ 180^{\circ}} [/tex]
[tex] \sf \longrightarrow {85^{\circ}\ +\ 23^{\circ}\ +\ x\ =\ 180^{\circ}} [/tex]
[tex] \sf \longrightarrow {108^{\circ}\ +\ x\ =\ 180^{\circ}} [/tex]
[tex] \sf \longrightarrow {x\ =\ 180^{\circ}\ -\ 108^{\circ}} [/tex]

A recent survey of 8,000 high school students found that the mean price of a prom dress was $195. 00 with a standard deviation of $12. 0. Alyssa thinks that her school is more fashion conscious and that students spent more than $195. 0. She collected data from 20 people in her high school and found that the average price spent on a prom dress was $208. 0. Which of the following are the correct null hypothesis and alternate hypothesis? H0: Mu = 195; Ha: Mu greater-than 195 H0: Mu not-equals 195; Ha: Mu = 208 H0: Mu = 195; Ha: Mu not-equals 195 H0: Mu = 195; Ha: Mu greater-than-or-equal-to 208.
The correct null hypothesis and alternate hypothesis will be
[tex]H_{0} =\mu=195\\H_{a} =\mu > 195[/tex]
What will be the correct null hypothesis and alternate hypothesis?It is given that
The mean price of a prom dress was $195. 00 with a standard deviation of $12. 0
Given that Alyssa thinks that her school is more fashion-conscious and that students spent more than $195.00.
She collected data from 20 people in her high school and found that the average price spent on a prom dress was $208.00.
Since she wants to check whether the sample mean [tex]\mu[/tex] is the same as the population mean [tex]\mu[/tex] = 195
[tex]H_{0} =\mu=195\\H_{a} =\mu > 195[/tex]

what is the area for this shape
Answer:
area = 697.5 ft²
Step-by-step explanation:
Think of an outer large rectangle minus a smaller upper rectangle.
area = LW - lw
area = (45 ft)(20 ft) - (45 ft - 10 ft - 8 ft)(7.5 ft)
area = 900 ft² - (27 ft)(7.5 ft)
area = 900 ft² - 202.5 ft²
area = 697.5 ft²

Bryan's volunteer group can build a garage in 12 hours. When he works with Sequoia's volunteer
group, it takes 4 hours to build the garage together. How long does it take Sequoia's volunteer
group to build the garage alone? (Do not include the units in your answer. )
Answer:
Step-by-step explanation:
Known:
A fraction represents a part of a whole or, more generally, any number of equal parts.Given:
The volunteer group can build a garage in 12 hours. Sequoia's group can build it inTo find:
The Bryan's long would it take them if they worked together.Brian's group ⇒ 1 garage in 12 hours ( [tex]\frac{1garage}{12hours}[/tex])
Sequoia's group ⇒ 1 garage in 16 hours ([tex]\frac{1garage}{16hours\\}[/tex])
To make it easier to calculate the time it would take if they worked together, we will write this expression:
[tex]\frac{1}{12} +\frac{1}{16} =\frac{4}{48} +\frac{3}{48} =\frac{7}{48} \\[/tex]
From this fraction we see that for 7 garages they would need 48 hours. . To calculate how much time they would need for
1 garage, we will further simplify the fraction.
Solving the worked together is would need
6.86 hours for one garage.

A factory produces 1,250,000 toys each year. the number of toys is expected to increase by about 150% per year. which model can be used to find the number of toys, n (in millions), being produced in t years? n = startfraction 2.5 (1.5) over t endfraction, t not-equals 0 n = 1.5 t squared 1.25 n = 1.5 t 1.25 n = 1.25 times 2.5 superscript t
The model that can be used to find the number of toys is 1.25* (2.5) ⁿ.
What is meant by an increment of 150%?
An increment of 150% means an increment of 1.5 times of initial value.
Number of toys initially = 1,250,000 or 1.25 millions
Number of toys after a year = 1.25 + 1.25*1.5 = 1.25*(2.5)¹
Number of toys after two year =1.25 * 2.5+ 1.25*2.5*1.5 = 1.25*(2.5)²
Number of toys after three year = 1.25* (2.5)³
So, Number of toys after n year = 1.25* (2.5) ⁿ
Therefore, the model that can be used to find the number of toys is 1.25* (2.5) ⁿ.

⠀
We have to find the two numbers a and b such that,

Obviously, the two numbers are 3 and 13.

[tex]\longrightarrow \sf \qquad {x}(x - 3)+ 13(x - 3) = 0[/tex]
