Thank you so much
The equation that represents this description is h = 20c + 60 because hours (h) is our dependent variable and cost (c) is our independent variable. Hours (h) is our dependent variable because it depends on how many hours Mr. Z tutors the students. The slope of the function is 20 because that is how much Mr. Z charges to start off. What was this student's mistake? What is the correct equation that represents the description above?
Answer:
c= 20h + 60
Step-by-step explanation:
The correct dependent variable for this equation is "c" cost of Mr Z's tutoring. The independent variable is "h" hours of tutoring. This is because the independent variable h hours should determine the cost of tutoring c. Therefore the equation can be interpreted: if there are h hours of tutoring which cost 20 per hour, total cost is equal c. Also slope of the equation is 20, coefficient of h.
Find value of each variable.

Answer:
-80, -60, -40, -20, 0, 20
Step-by-step explanation:
I don't even know if I am right, sorry
Answer:
-20, -40, -80
Step-by-step explanation:
as we see in the whole number (aka positive number) area, its counting by twenties because it goes from 0-20. since were in the negative area we would want to count up backwards,
so, 0 minus 20 equals -20
-20 minus -20 equals -40
and -20 minus -60 equals -80

Step-by-step explanation:
Hope this helps :)
Answer:
Inequality: [tex]250\geq s+85\\[/tex]
Solution:[tex]s\leq 165[/tex]
Step-by-step explanation:
The maximum number of students is 250 so the number of students (s) who can still participate plus the number already registered must be less than 250. This can be written as [tex]250\geq s+85\\[/tex].
Form here solve for s by subtracting 85 from both sides.
[tex]250-85\geq s[/tex]
250-85=165
[tex]s\leq 165[/tex]

Ramon earns $1,780 each month and pays $53.30 on electricity. To the nearest tenth of a percent, what percent of Ramon's earnings are spent on electricity each month?
Ramon spends ......% of his earnings on electricity each month.
Answer:
3.0%Step-by-step explanation:
Ramon earns $1,780Ramon pays $53.30 on electricity$53.30 of $1780 is:
53.30/1780*100% = 2.9943% = 3.0% roundedAnswer:
3%
Step-by-step explanation:
The first step is to write 53.3 as a fraction of 1780, which is simply
53.3/1780
Now we need to multiply the numerator and denominator of the fraction by 10 to get rid of the decimal
53.3/1780 = 53.3/1780 x 10/10=533/17800
Now we just need to convert this fraction to a percentage :
533/17800 = 2.99438202247191
2.99438202247191 to the nearest tenth simpifies to 3
So, $53.3 is about 3% of $1780
A plane flying due west at 120 m/sec is blown due south at 54 m/sec. by a strong wind. Find the plane’s resultant velocity and direction angle as a degree.
velocity = ___ m/sec (round answer to nearest whole number)
Direction angle = ____ ° (round answer to nearest whole number)
Answer:
1) Velocity = 132 m/sec
2) Direction angle = 24° South of West
Step-by-step explanation:
1) The speed with which the plane is flying, [tex]v_{plane}[/tex] = 120 m/sec
The direction in which the plane is flying = Due West
The speed of the blowing strong wind, [tex]v_{wind}[/tex] = 54 m/s
The direction of the strong wind = Due South
The vector form of the given velocities are;
[tex]v_{plane}[/tex] = -120·i
[tex]v_{wind}[/tex] = 54·j
The resultant velocity in vector format, [tex]\underset{\textbf{v}}{\rightarrow}[/tex] is given as follows;
[tex]\underset{\textbf{v}}{\rightarrow}[/tex] = -120·i + 54·j
Therefore, the magnitude of the resultant velocity, [tex]\left |\underset{v}{\rightarrow} \right |[/tex], is given as follows;
[tex]\left |\underset{v}{\rightarrow} \right |[/tex] = √((-120)² + (54)²) = 131.590273197
∴ The magnitude of the plane's resultant velocity, [tex]\left |\underset{v}{\rightarrow} \right |[/tex] ≈ 132 m/sec, when rounded to the nearest whole number
2) The direction angle of the plane's resultant velocity, θ, is given as follows;
[tex]\theta = arctan \left ( \dfrac{\left |v_{wind}\right |}{\left |v_{plane}\right |} \right)[/tex]
Therefore, by substituting the known values, we have;
[tex]\theta = arctan \left ( -\dfrac{54}{120} \right) = -24.227745317954169522385424019918 ^{\circ}[/tex]
∴ By rounding to the nearest whole number, the direction angle of the plane's resultant velocity = θ ≈ -24° = 204° which is 24° South of West.
Scott collects hats. He has 65 hats an plans on buying 80 per year.
1. Write an equation that represents the total number of hats collected?
2. When will he have 465 hats?
3. How many will he have in 10 years?
Answer:
80x+65 2.465 3.865
Step-by-step explanation:
x being the number of years so in ten years he will have 80x10=800+65=865
80x5=400+65=465 so 5 is the number of years it would take
and i do not understand number 1 but i put a formula just in case that was it
Margarite owns a boutique. She sells her jewelry at a 30% markup. If she buys a bracelet for $22, what would she sell it for after the markup?
Answer:
selling price is $26.4
Step-by-step explanation:
Here, we want to apply the markup percentage so as to get the price of the jewelry
mathematically, we have the selling price as;
$22 + (30% of $22)
= $22 + 4.4
= $26.4

Answer:
Perpendicular
Step-by-step explanation:
determine the value of , if possible. If the triangles are congruent, state which triangle congruence condition you used. If the triangles are not congruent or if there is not enough information, state, “Cannot be determined”.
Answer:
"Can't be determined"
Step-by-step explanation:
From the triangles given in the picture,
Given:
m∠A = m∠C
m∠B = m∠D
But for the congruence of these triangles third condition is not given.
Therefore, congruence of these triangles can not be determined.
So the answer is "Can't be determined"

Solve both for the x and y values to use and graph
2x - 3y = -12
x + y = 9
You don’t need to graph it I just need the x and y and work for both equations.
Step-by-step explanation:
x + y = 9. => 2x + 2y = 18.
2x + 2y = 18
- (2x - 3y = -12)
=> 5y = 30, y = 6.
Therefore x + (6) = 9, x = 3.
The solution is x = 3 and y = 6.
the simple interest on 2.000 for 5 years is $500, then what is the interest rate?
Answer:
5%
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 2000 × 0.05 × 5 = 500
I = $ 500.00
The simple interest accumulated
on a principal of $ 2,000.00
at a rate of 5% per year
for 5 years is $ 500.00.

Which algebraic representation matches the reflection above?
O A. (x, y) = (x,y)
B. (x, y) -(-x, y)
OC. (x,y) (x,-))
OD. (x, y) (-X, -y)
The algebraic representation which matches the above reflection is D. (x, y) → (-x, -y).
What is Reflection?Reflection is a type of geometric transformation where the figure is flipped. In other words, a figure when undergoes reflection becomes it's mirror image.
From the graph, it is seen that a quadrilateral is reflected across the Y axis.
Find the corresponding coordinate points of the quadrilateral in order to find the algebraic representation.
From the first figure, consider the vertex point (1, 1).
The corresponding point on the second figure is (-1, -1).
That is, the point (x, y) is changed to (-x, -y).
So the representation is (x, y) → (-x, -y).
Hence the correct algebraic representation is (x, y) → (-x, -y).

Answer:
One possible side length could be a length of 6.7.
Step-by-step explanation:
We can assume that the hypotenuse of the triangle is 9 and one side length is 6. We can find the third side length using the pythagorean theorem [ a² + b² = c² ]. Use what we are given and solve for b.
6² + b² = 9²
36 + b² = 81
b² = 45
b ≈ 6.7
Best of Luck!
