Ash cannot decide which of two washing machines to buy. The selling price of each is $360. The first is marked down by 30%. The second is marked down by 10% with an additional 20% off. Find the sale price of each washing machine. Use pencil and paper. Explain why ash should buy the first washing machine rather than the second if the machines are the same except for the selling price.
Answer:
The answer is the first one.
Step-by-step explanation:
Okay, so the first one is solved like this:
You do 360*30%. 30% is 0.3 in decimal form. So 360*0.3=108. 108 is the amount that is discounted, NOT the price. You have to do 360-108, which is 252. The discounted price is $252.
Now the second one is solved like this:
You do 360*10% FIRST because the problem says it was marked 10% BEFORE the 20%. 10%=0.1, so 360*0.1=36. You subtract 360-36, which is 324. Then, you multiply 324 by 20% or 0.2, to get 64.8, which is the discount of 20%. You subtract 324-64.8, which is $259.20. So the first one is the answer because it is cheaper since 252 is less than 259.20. If you need this explanation, don't use this word for word. Summarize this in YOUR own words!
He should by the first washing machine because it cost less than the second washing machine.

Please help me, I don’t know how to solve for x on this one
Use trigonometry to solve for x.
The tangent function is defined to be opposite side divided by the adjacent side.
tan(78) = x/10
tan(78)(10) = x
47.0463010948 = x
We now round off to two decimal places. In other words, we round off to the nearest tenths.
47.05 = x
Done!

1/4x-3/4=7/x solving the following rational equation for x
Answer:
x¹= -4 , x²= 7
Step-by-step explanation:
1) Determine the defined range
¼x-¾=7/x =/ 0
2) Move the expression to the left-hand side and change its sign
[tex] \frac{1}{4} x - \frac{3}{4} - \frac{7}{x} = 0 \\ \\ [/tex]
3) Write all numerators above the least common denominator 4x
[tex] \frac{ {x}^{2} - 3x - 28 }{4x} = 0[/tex]
4) When the quotient of expressions equals 0, the numerator has to be 0
x²-3x-28=0
5) Write -3x as a difference
x²+4x-7x-28=0
6) Factor out x from the expression
x(x+4)-7x-28=0
7) Factor out -7 from the expression
×(x+4)-7(x+4)=0
8) Factor out x+4 from the expression
(x+4)×(x-7)=0
9) When the product of the factors equals 0, at least one factor is 0
x+4=0
x-7=0
10) Solve for the x
x+4=0 -> x= -4
x-7=0 -> x=7
11) Check if the solution has defined range
x= -4
x=7
12) The solution has 2 solutions
[tex]x1 = - 4 \: \: x2 = 7[/tex]
Answer:
The correct answer is -9

If A = {x | x is an odd integer), B = {x | x is an even integer), C = {2,3,4,5), and D = {3,4,5,6), list the element(s) of the following set.
Answer:
Answer: 3,4,5,6 can be the complete list for the f(x).
Step-by-step explanation:
Given a polynomial function f(x) which is a fourth degree polynomial .Therefore it must has 4 roots.
Let's check all the options for the possible list of roots of f(x)
1) 3,4,5,6 can be the complete list for the f(x) .
Option 2) and option 3) cannot be the complete list for the f(x) as it has one complex root and complex roots occur in pair.
Option 4) cannot be the complete list for f(x) as complex roots occur in pair and they conjugates but conjugate of 5+i is 5-i(which is not given) not -5+i
Fill in the table so it represents a linear function.

? Question
A bike shop offers three kinds of cycles-tricycles, bicycles, and unicycles. Together, the cycles in the shop have a total of
98 wheels and 46 seats. (Tricycles have 3 wheels, bicycles have 2 wheels, and unicycles have 1 wheel. All cycles have 1 seat.)
There are twice as many bicycles as tricycles. How many of each type of cycle are in the shop?
Answer:
Number of Uni Cycles = 7
Number of Bi Cycles = 26
Number of Uni Cycles = 39
Total Wheels = 98
Total Seats = 46
Step-by-step explanation:
Uni Cycles consist of 1 wheel
7 x 1 = 7 wheels
Bi Cycles consist of 2 wheels (twice than tri cycle)
26 x 2 = 52 wheels
Tri Cycles consist of 3 wheels
13 x 3 = 39 wheels
Total seats = 7 + 26 + 13 = 46
Total wheels = 7 + 52 + 39 = 98
The number of cycles is given below:-
Number of Uni Cycles = 7
Number of Bi Cycles = 26
Number of Uni Cycles = 39
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Total Wheels = 98
Total Seats = 46
Uni Cycles consist of 1 wheel
7 x 1 = 7 wheels
Bi Cycles consist of 2 wheels (twice as tricycle)
26 x 2 = 52 wheels
Tri Cycles consist of 3 wheels
13 x 3 = 39 wheels
Total seats = 7 + 26 + 13 = 46
Total wheels = 7 + 52 + 39 = 98
