Mr. W is having a yard sale, where he is selling iPad chargers and wireless keyboards. At the
end of the day, he knows he sold a maximum of 14 items, and he earned a total of $342. If he
charged $18 for each iPad charger (x) and $38 for each keyboard (y), write a system of
inequalities that models this situation,
Answer: the system of inequalities are
x + y ≤ 14
18x + 38y = 342
Step-by-step explanation:
Let x represent the number of iPad chargers sold.
Let y represent the number of keyboards sold.
At the end of the day, he knows he sold a maximum of 14 items. This is expressed as
x + y ≤ 14
If he
charged $18 for each iPad charger (x) and $38 for each keyboard (y) and earned a total of $342, the expression would be
18x + 38y = 342

2. You flip a coin two times. What is the probability that you get heads each
time?
Answer: 25%
Step-by-step explanation: So, I think we know it's 50% chance to get heads or tails. But what's the chance of getting heads two times in a row....let's see...
[tex]\frac{1}{2} * \frac{1}{2} = \frac{1}{4}[/tex]
Let's turn [tex]\frac{1}{4}[/tex] into a decimal...
1 ÷ 4 = 0.25
0.25 * 100 = 25
= 25%
Thus, you have a 25% to get heads two times in a row...I hope this helps!

Round to one decimal place (BRAINLIEST)
Answer:
4.3
Step-by-step explanation:
Apply trigonometric ratios to find the answer.
Firstly, we need to find the measure of angle theta. In order to do this, we will use triangle BAD.
From angle theta, the trigonometric ratio sine can be used:
sinθ = [tex]\frac{4.1}{5.3}[/tex]
After we find the value, we take the inverse sine of it and the result is approximately 50.7 degrees.
Now, knowing that angles BAD and CAD are the same, we can solve for CD using trigonometric ratio sine.
sin50.7 = opposite/hypotenuse
sin50.7 = CD/5.5
sin50.7 * 5.5 = CD
4.3 ≈ CD

An art teacher needs to buy at least 60 brushes for her class. The brushes are sold in packs of 8. In which inequality does n represent the minimum number of packs the teacher needs to buy for her class?
Answer:
I think 8n >_ 60
Im not sure but thats what i put
Step-by-step explanation:
The inequality where n represents the minimum number of packs the teacher needs to buy is: 8n ≥ 60.
What is Inequality?Inequality is an expression or statement of an order relationship, which involves the use of inequality signs, variables, numbers and/or algebraic expressions.
Thus:
n = number of brushes in a pack
The teacher must buy 60 brushes and above.
Thus:
8n ≥ 60 will represent the minimum number of brushes for the class.
Therefore, the inequality where n represents the minimum number of packs the teacher needs to buy is: 8n ≥ 60.

A = 26.4 × 12.6 = 332.64 m²
On a coordinate plane, 2 exponential functions are shown. Function f (x) approaches y = 0 in quadrant 2 and increases into quadrant 1. Function g (x) approaches y = 0 in quadrant 1 and increases into quadrant 2.
Which function represents a reflection of f(x) = Three-eighths(4)x across the y-axis?
g(x) = NegativeThree-eighths (one-fourth) Superscript x
g(x) = Negative three-eighths(4)x
g(x) = Eight-thirds(4)-x
g(x) = Three-eighths(4)–x
Answer:
[tex]g(x)=f(-x)=\frac{3}{8}(4)^{-x}[/tex]
Step-by-step explanation:
The pre-image is
[tex]f(x)=\frac{3}{8}(4)^{x}[/tex]
To make a reflection across the y-axis, we need to apply the transformation
[tex](x,y) \implies (-x,y)[/tex]
Which give the function
[tex]g(x)=f(-x)=\frac{3}{8}(4)^{-x}[/tex]
Therefore, the right answer is the last choice.

The height of the basketball at 1 second will be 24 feet. Then the correct option is A.
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
A basketball is shot into the air. Its height is represented by the polynomial equation which is given below.
h(t) = –16t² + 35t + 5
Where h is the height of the basketball at t seconds.
The height of the basketball at 1 second will be given as,
h(1) = –16 × (1)² + 35 × 1 + 5
h(1) = –16 + 35 + 5
h(1) = –16 + 40

Step-by-step explanation:

(08.01) Line H is represented by the following equation: 2x + 2y = 8 What is most likely the equation for line K so the set of equations has infinitely many solutions? x + 2y = 2 x + y = 4 2x + y = 6 x − y = 8
Answer:
The second option you listed: x + y = 4 gives the same line as H, and therefore renders infinite number of solutions (as many as every point on the line)
Step-by-step explanation:
We need to look for the equation that exactly matches the given one :
2 x + 2 y = 8
notice dividing both sides of this equation by "2" we get:
x + y = 4
SO this equation represents exactly the same line as 2 x + 2 y = 8 does, and therefore their graphs overlap completely
What is the value of b?
A. 100
B. 90
C. 80
Answer: the answer is C. 80°
Step-by-step explanation:
= 360 - 110 - 90
=160°
b=1/2 (160)
b=80°
Answer:
C. 80 degrees
Step-by-step explanation:
The measure of the given arcs are 90 and 110.
Subtract those values from 360
= 360 - 90 -110
= 160
The angle b is half of 160 degrees, the measure of the arc that intercepts it.
Therefore, it measures 80 degrees.

The value of a car depreciates by 40% each year. At the end of 2007 the value of the car was £3600 Work out the value of the car at the end of 2006 asap ples
Answer: $6,000
Step-by-step explanation: If set up correctly, the value of the car at the end of 2006 times 0.6 (because the car is losing 0.4 of its value, so it keeps 0.6 of its value) should get you the value of the car at the end of 2007.
The equation should look like this:
(value of the car at the end of 2006) x 0.6 = (value of the car at the end of 2007)
Then you substitute: (value at the end of 2006) x 0.6 = 3600
Then divide: (value at the end of 2006) = 0.6 ÷ 3600
Then substitute again: (value at the end of 2006) = 6,000

John charges a flat fixed fee of $10 PLUS a certain rate per hour for each hour for cutting the grass. John earned $100 one day, cutting the grass in a circular lawn. On the next day, to cut the grass in a similar adjacent circular lawn one third the circumference, how much money can he expect to make? ( with explanation )
Answer:
33.33 dollars
Step-by-step explanation:
Answer:
$20
Step-by-step explanation:
Of the $100 John earned, $90 was for his hourly charge, which we assume is proportional to the area being mowed.
A lawn with 1/3 the circumference has (1/3)^2 = 1/9 the area, so presumably takes 1/9 of the time to mow. John's hourly charge for the smaller lawn will be $90/9 = $10. Added to his flat fee, he can expect to be paid $20.
_____
The ratio of areas of similar figures is the square of the ratio of any of the linear dimensions. All circles are similar. Circumference is measured in "units" and area is measured in "square units." So, circumference is a linear dimension (units to the first power).
