A cashier checks the price of a dining room table that is marked $369, because it is usually rings up to, $410. What percentage is the discount?
Answer:
10% discount
Step-by-step explanation:
If you take 369 divided by 410 it gives you 0.9 which is equal to 90% which then leads us to realized that if 369 is 90% of 410 then the discount would have to be 10%

Answer: C (I think) and the slope is 2/5, the points on the graph are (0,0) (5,2) (10,4) (15,6)
Step-by-step explanation: Nothing is being multiplied in the equation like in the other two answers, and slope is always change in y/change in x
Ill give brainiest to, whom ever gets this correct.
Answer:
50.2 m^2
Step-by-step explanation:
The Area of a circle is given by the equation pi(r)^2
Therefore if r = 4 we can plug it into the equation to get:
pi (4)^2= pi(16)= 50.2655 or about 50.2 m^2Find the value of the sum ∑j=131(6j2−7j+4)

Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the model is to be used only for the scope of the given data and consider only linear, quadratic, logarithmic, exponential, and power models. Use a calculator or computer to obtain the regression equation of the model that best fits the data. You may need to fit several models and compare the values of R2.

-15/-18=10/x
what is X?
Answer:
12
Step-by-step explanation:
(-15)/(-18) = 10/x cross multiply expressions
-15x = -180 since both sides are negative we can write without the sign
15x = 180 divide both sides by 15
x = 12

Which expression has a value of 48?
A) (4+5) ･3²-9÷3²
B) 4+5 ･(3²-9) ÷3²
C) 4+5 ･3² (-9÷3²)
D) 4+5 ･3² -9÷3²
(This question was already asked and answered but they said the answer was wrong on didn’t give the right answer)
Step-by-step explanation:
D)4+5×3^2-9÷3^2
=4+5×9-9÷9
=4+5×9-1
=4+45-1
=49-1
=48
Khan Academy Slope from graph !! Please help me I am having so much trouble !!!! PLEASEEE HELPPPPPPPP
Answer:
The slope of this line is 5/3. Or, 1 2/3. The equation would be y = 5/3x
Step-by-step explanation:
You are in luck my friend!
To find the slope of a line on a graph, you need to find the rise over run. You need to pick two definite points on a graph. An intersection whereyou can clearly tell the value. For example 1,1 and -4,-4. Then use your finger and trace how many units up you have to go, and then how many units across. (This is a very common topic so if you need further help just look up rise over run. This fact will put you ahead, do you see how the line intersects between the 2 and the 3 in the y axis? This is called the y intersect, you will see it added to the slope so if the equation is y = 5/3x it would be written as y = 5/3x + 2.5 because that is where the line intersects with the y axis.) Back to slope, remember that the formula is always rise/run. Later, you will find to points and use a slope formula. y2-y1/x2-x1.

Name the missing coordinate(s) of each triangle
Answer:
13) C (a, a) Y (a, 0)
14) B (0, b) P (a, 0)
Step-by-step explanation:
13) Y lies on x axis so it is Y(a,0)
ZY = YC = a
so for C coordinates are (ZY,YC) = (a, a)
14) B lies on y axis so it is B(0, b)
BK = BP = [tex]\sqrt{a^{2} + b^{2} }[/tex] = distance between two points
so P is (a, 0) as it is same distance and on positive side of x axis

A line has a slope of zero. Which of the following points could this line pass through?
(3, -6) and (7, -6)
(-8, 6) and (8, -6)
(12, 9) and (12, 6)
(3, 4) and (4, 6)
Answer:
A line has a slope of zero. Which of the following points could this line pass through?
(3, -6) and (7, -6)
(-8, 6) and (8, -6)
(12, 9) and (12, 6)
(3, 4) and (4, 6)
(-8, 6) and (8, -6)
(12, 9) and (12, 6)
(3, 4) and (4, 6)
Step-by-step explanation:
The answer would be (3,-6) and (7,-6) because if the slope is zero it wouldn't go any where it would stay the same, and I'm pretty sure it would be negative.
Jessica purchased a book that was on sale for 12%. The sales tax is 3% key y represent original price of the book write an expression that can be used to determine the final cost of the book.
How do I do this, I don’t need a answer just how to do I it lol
Answer:
What is a sales tax decalculator?
Step 1: take the total price and divide it by one plus the tax rate.
Step 2: multiply the result from step one by the tax rate to get the dollars of tax.
Step 3: subtract the dollars of tax from step 2 from the total price.
Pre-Tax Price = TP – [(TP / (1 + r) x r]
TP = Total Price.

Mr townsend needs to make 13 pairs of butterfly for customers for a play. Each pair of wings is made with 3/4 yard of fabric. The fabric costs $8 per yard.
You’ll apply properties of multiplication in the following steps to find the total cost of fabric.
1. Use multiplication to write an expression for the amount of fabric needed to make 13 pairs of wings.
2. Multiply the amount of fabric by the price per yard to find an expression for the total costs.
3. Use the associative and commutative properties to rearrange the terms in the expression to make it easier to calculate. Explain why the rearranged expression is easier to work with.
4. Simplify your expression to find the total costs. show your work

Alex had 12 gumball machines. Each had about 47 gumballs.
Using compatible numbers, what is the best estimate for the number of gumballs Alex had?
Alex had about ______ Gumballs
DO I do Multiplication or whattt
Answer:
The answer would be 600 gumballs.
Step-by-step explanation:
The first step that you would do to solve this problem is multiply 12 by 47, which would give you 564.
The second step that you would do is round it. 564 rounded to the hundredths place is 600.
Therefore, your answer is 600.
Answer: 500
Step-by-step explanation:
its 500 round 47 u get 50 then round 12 u get 10 50 . 10=500
