An airplane travels 500 miles an hour then it will take 8 hours to travel 4.000 miles.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
An airplane travels 500 miles an hour. We need to find how long it will take to travel 4.000 miles.
We know that
Let t be the time taken by an airplane to travel 4000 miles.
An airplane traveled 500 miles = 1 hour
An airplane traveled in 1 mile = 1/ 500
An airplane traveled in 4000 miles = 4000/500
= 8 hour
Thus, It will take the airplane 8 hours to travel 4,000 miles.

A sporting goods store bought a ski set at a cost of $432. Later, the ski set was marked down 10% from its selling price and then marked down another 20%. The total markdown is the greatest possible markdown without the store losing money. Find the original selling price.
Answer:
The original selling price of the ski set is $600
Step-by-step explanation:
The cost price of the ski set = $432
The first percentage mark down of the ski set = 10% from its selling price
The first percentage mark down of the ski set = 20% from its selling price
Let x represent the original selling price of the ski set at the sporting goods store, we are given;
80/100 × (90/100 × x) = The cost price of the ski set
Therefore, we have;
80/100 × (90/100 × x) = 432
0.72 × x = 432
x = 432/0.72 = 600
Therefore, the original selling price of the ski set, x = $600

The question of the pic was cut off at the top and it says -
Line W is graphed on the coordinates plane below.
Answer: A
Explanation:
Step 1: Use the linear graph to create an equation using slope-intercept form. The y-intercept is (0,-6) because that's where the line passes the y-axis. The slope is 1/2 and that's pretty self-explanatory if you know how to find slope. The equation would be y=1/2x-6.
Step 2: Because we are looking for a line perpendicular to the linear graph, the y-intercept and slope needs to be different. If they're perpendicular, they need to intersect, so the slope needs to be the reciprocal of the original slope, 1/2. The reciprocal is -2. Your equation would be y=-2x+b, and since we don't know the y-intercept, we would leave it as b.
Step 3: Plug in the given ordered pair, (-3,-2), to get -2=-2(-3)+b. You would result with -2=6+b. Subtract 6 to both sides and you would get b=-8.

Answer:
y = -3/4x -1
Step-by-step explanation:
The given equation is in the slope-intercept form, which lets you see that its slope is 4/3.
The slope of the perpendicular line will be the negative reciprocal of this:
-3/4
Then the slope-intercept form equation will be ...
y = -3/4x +b . . . . . . for some b
We can find the value of b that makes the line go through (4, -4) by using those values in this equation.
-4 = -3/4(4) +b
-4 +3 = b . . . . . . . . add 3
-1 = b
Then the equation you're looking for is ...
y = -3/4x -1

The value of a new car decreases by about 15% in the first year. How much will a car be worth after one year if its initial value was $1,500? If you get stuck, consider using diagrams or a table to organize your work.
Answer:
After one year, the car will be worth $1,275.
Step-by-step explanation:
We know that a new car value decreases by 15% every year. So, we first need to find 15% of $1,500.
1,500 x 0.15 = $225.
Now, me must subtract $225 from the initial value, or $1,500.
1,500 - 225 = $1,275
Therefore, after one year, the car will be worth $1,275.
Hope this helps! :D

Victoria uses
3/16
cup of flavored syrup to make an Italian soda. She has 2 cups of flavored syrup left. How many Italian sodas can she make?
A.
9 3/8
B.
10 2/3
C.
11 1/4
D.
12 1/2
Answer:
B. or 10 2/3
Step-by-step explanation: Because if she had only 2 cups left then 1 cup can make 5 drinks so 10 then the rest would be a fraction.
She can make 32/3 of Italian sodas with 2 cups of flavored syrup.
What is a fraction?
A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, Victoria uses 3/16 cups of flavored syrup to make an Italian soda.
Assume that 3/16th of x is 1.
∴ (3/16)x = 1.
3x/16 = 1.
3x = 16.
x = 16/3,
Now from 2 cups of flavored syrup, we can make 2x of Italian soda.
Which is (16×2)/3.
= 32/3

How do solve this question? Find an equation of a line parallel to the given line and contains the given point. Write the equation in slope–intercept form. With the equation 2x + 5y= -10 point (10, 4).
Answer:
y = -2/5 x + 8Step-by-step explanation:
First we need to find the slope of the given line;
Given the line 2x + 5y= -10, we need to write it in standard form of y = mx+c
Make y the subject of the formula;
2x + 5y= -10
5y = -2x-10
y = -2x/5-10/5
y = -2x/5 - 2
Hence the slope of the line m = -2/5
Since the equation of the line we need is parallel to this line, hence they will have the same slope.
The slope of the required line = -2/5
Get the intercept;
Substitute the point (10,4) and m = -2/5 into the equation y = mx+c
4 = -2/5(10)+c
4 = -4 + c
c = 8
Get the required equation;
y = mx+c
y = -2/5 x + 8
Hence the equation of a line parallel to the given line and contains the given point is y = -2/5 x + 8
