1) You are taking a Tae Kwon Do class that costs $15 a month. In addition, you needed to
purchase a uniform. You paid a total of $108 after 6 months. Write an equation that glves
the total cost (in dollars) as a function of the length of time you have been taking classes
(in months). Find the total cost after 9 months.
Answer:
$162
Step-by-step explanation:
you divide 6 months by 2 then you divide 108 by 2 then you add the half of 108 and plus it to 108 then you get your total.
The function of the length of time you have been taking classes is f(x) = 15x and cost for 9 months is $135
What is unit rate?A unit rate means a rate for one of something.
Given that, You are taking a TAE Kwan Do class that costs $15 a month. In addition, you needed to purchase a uniform. You paid a total of $108 after 6 months.
We have unit rate = $15 per month
Since, one month cost is $15 therefore, for 6 months = 15×6 = $90
Therefore, cost of uniform = $108 - $90 = $18
Let you are taking classes for x months, the function of the length of time you have been taking classes,
f(x) = 15x
For 9 month cost =
f(9) = 15×9 = 135
Hence, the function of the length of time you have been taking classes is f(x) = 15x and cost for 9 months is $135

please help please i need help
Answer:
d + 85
Step-by-step explanation:
Look at it like this,
suppose you have 1 DVD, and the mother buys 85 DVDs then you have 1 + 85 = 86 DVDS
or when you have 2 DVDs, then you have 2 + 85 = 87 DVDs afterwards.
notice that you always take the number of DVDs you already have, and add 85 to it.
d is just a number, but you just don't know it yet. you can change d by any number, and you know d+85 is the number of DVDs afterwards
STEAM: The boiling pint of water is affected by changes in elevation. Use the expression of -2A/1000 where a represents the altitude in feet to find the number of degrees Farenhite at which the boiling point of water changes at altitude 5,000 feet
A) -10°F B) 20°F C) 10°F D) -20°F
Answer:
A) -10°F
Step-by-step explanation:
Given that:
Boiling point of water gets affected when there is a change in the elevation.
Expression to represent the temperature i.e. boiling point w.r.to altitude [tex]A[/tex] is given by the equation:
Temperature in [tex]^\circ F[/tex] = [tex]\frac{-2A}{1000}[/tex]
Given that, the altitude, [tex]A[/tex] = 5,000 feet
To find:
The number of degrees Farenhite at which the boiling point of water will change.
Solution:
Here, we are given the expression:
Temperature in [tex]^\circ F[/tex] = [tex]\frac{-2A}{1000}[/tex]
And value of altitude, [tex]A[/tex] = 5,000 feet
Let us put the value of [tex]A[/tex] in the equation and let us find the value of temperature in [tex]^\circ F[/tex].
Temperature in [tex]^\circ F[/tex] =
[tex]\frac{-2\times 5000}{1000}\\\Rightarrow -2\times 5\\\Rightarrow \bold{-10^\circ F}[/tex]
Therefore, the answer is:
A) -10°F

The tape diagram models the lengths of two snowboarding trails. The beginner trail is
200 meters long. How long is the expert trail?
Beginner Trail
Expert Trail
The expert trail is
meters long
2)
The length of the expert trail is 800 meters. We can find our answer by using given tape diagram and simple mathematical calculations.
What is tape diagram?
A tape diagram is a visual model resembling a piece of tape, that is used to assist with the calculations of ratios and addition, subtraction and commonly multiplication.
Here,
Length of the Beginner trail is 200 meters
And also expert trail is 4 times to Beginner trail.
So, Expert trail = 4 * Length of beginner trail.
Expert trail = 4* 200
= 800 meters.
Hence, we get the answer.

To practice for a competition, Alexia swam 0.54 kilometers in the pool each day for 2 weeks. How many meters did Alexia swim in those 2 weeks?
Answer:Alexia swam 7,560meters in 2 weeks
Step-by-step explanation:
Step 1
7 days = 1 week
therefore 2 weeks = 7 x 2 = 14 days
Step 2
Each day Alexia swam = 0.54 kilometres
So in 14 days( 2 weeks) She swam = 14 x 0.54 km= 7.56km
Answer is needed in meters
so 1000 m = 1km
Therefore 7.56 km = 7.56km x 1000=7,560meters

Quaddlateral CART is dilated with the center at the origin and a scale
factor of 6/5
Describe Quaddlateral CART and Quadrilateral C’A’R’T’by completing the
table below with the BEST answer
Answer:
Step-by-step explanation:
Rule for the dilation of a point by a scale factor 'k' about the origin is,
(x, y) → (kx, ky)
If the scale factor for the dilation is [tex]k=\frac{6}{5}[/tex],
Rule for the dilation,
A(x, y) → A'[tex](\frac{6}{5}x,\frac{6}{5}y)[/tex]
If the coordinates of point A' (Image) is given and we have to find the coordinates of point A (Preimage),
Rule for the dilation,
A'(x, y) → [tex]A(\frac{5}{6}x,\frac{5}{6}y)[/tex]
Quadrilateral CART Quadrilateral C'A'R'T'

The two lines graphed on the coordinate grid each represent an equation. Which ordered pair represents a solution?
Answer:
The ordered pair (-3, 3) represents the solution of two lines on the coordinate grid.
Thus, option B is true.
Step-by-step explanation:
As we know that the point of intersection of two lines is the solution of the lines.
Given the graph of the lines, we can see that the two lines intersect at the point (-3, 3).
i.e. at x= -3, y = 3
The point of intersection is (-3, 3)
Thus, the ordered pair (-3, 3) represents the solution of two lines on the coordinate grid.
Thus, option B is true.
Answer:
B

motorcycle cover 210 kilometre distance with 5 l of petrol how many kilometre does it cover with 8 litre of petrol? how much petrol is needed to cover 588 kilometre
Answer:
A: 336 km
B: 14 L
Step-by-step explanation:
Use a proportion
210 km / 5 L = x / 8L Cross multiply
8*210 = 5 x
1680 = 5x
x = 1680 / 5
x = 336 km
===============
210 /5 = 588/x Cross multiply
210x = 588 * 5
210x = 2940 Divide by 210
x = 2940/210
x = 14 L

Answer: B. It is a perfect square
Step-by-step explanation:
Radical Expressions
Melissa multiplied [tex]\sqrt{a}[/tex] and [tex]\sqrt{b}[/tex] and got a rational number.
We are also given that a and b are both natural numbers. It means their product must be not only rational but also a natural number.
We can write that product like:
[tex]\sqrt{a} \cdot \sqrt{b}=\sqrt{a\cdot b}[/tex]
If the result is a natural number, then the product of a and b must be a perfect square. so the radical disappears.
