PLEASE HELP !!!!
The original price of a sofa is $500.
a. If the sofa price decreased by 20%, what is the new price?
b. The company can’t sell the sofa after 3 weeks so they reduce the price to $320. What is the percent decrease?
c. If the company reduces the price in week 4 to $290, what is the percent decrease?

Answer:

14.4

Step-by-step explanation:

If someone drinks 55%, that means 45% is left over.  You multiply 32 x 45 to find out what is left.

Answer:

14.4

Step-by-step explanation:

lets start with the 55% it means 55/100

so we need to calculate the the ounces that the person drank which is:

32*15/100=17.6ounces

now to get the ounces left we should subtract the ounces that was drunk from the 32 ounces which is:

32-17.6=14.4

Answer:

400 meters = 4000 centimeters

Step-by-step explanation:

Sorry if this didn't help

The solution is , 4,000 centimeters are equivalent to 40 meters. Hence, the answer is A) 4,000 cm.

An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, left-hand side (LHS) and right-hand side (RHS), connected by an equal sign (=). The LHS and RHS can contain numbers, variables, operators, and functions, and the equal sign indicates that the value of the expression on the LHS is equal to the value of the expression on the RHS.

Here,

we know,

100 centimeters = 1 meter

Since there are 100 centimeters in one meter, we can convert meters to centimeters by multiplying the length in meters by 100.

So, to convert 40 meters to centimeters, we can multiply 40 by 100:

40 meters = 40 x 100

= 4,000 centimeters

Therefore, 4,000 centimeters are equivalent to 40 meters. Hence, the answer is A) 4,000 cm.

Answer:

The answer is below.

Step-by-step explanation:

The options are not clear. I would solve a similar question.

A linear function is a function in the form:

y = mx + b;  where y and x are variables, m is the slope and b is the y intercept.

From the options:

a) x(y - 5) = 2

xy - 5x = 2.   Since the equation is not in the form of y = mx + b, hence it is not a linear function. It is a nonlinear function.

b) y - 2(x + 9) = 0

y - 2x - 18 = 0

y = 2x + 18. The equation is in the form of y = mx + b, hence it is a linear function.

c) 3y + 6(2 - x) = 5

3y + 12 - 6x = 5

3y = 6x - 7. The equation is in the form of y = mx + b, hence it is a linear function.

d) 2(y + x) = 0

2y + 2x = 0

2y = -2x. The equation is in the form of y = mx + b, hence it is a linear function.

Answer:

-10

Step-by-step explanation:

the upper right is the same (105°), therefore the left 75°

now you have 180 = 75 + x + 115

therefore: -10

Answer:

$149.64

Step-by-step explanation:

Recall that there are 12 months in a year.  Thus, 3 years would be 36 months.

$24.99 times 36 months comes to $899.64.  To determine how much more Maria will pay by making monthly payments is $899.64 less $750, or $149.64.

Answer:

x = 3/4

y = 5/4

Step-by-step explanation:

Step:

Substitute−x+2 for y in y=3x−1:

y=3x−1

−x+2=3x−1

−x+2+−3x=3x−1+−3x(Add -3x to both sides)

−4x+2=−1

−4x+2+−2=−1+−2 (Add -2 to both sides)

-4x = -3

x=3/4

Step: Substitute x into the original equation

y=-3/4 + 2

y=5/4

Jennifer made $59.

$22.50 times 2 is $45 and $2.75 times 3 is $8.25, the sum of these numbers is $53.25.

$5 plus $0.75 is $5.75, and the sum of $5.75 plus $53.25 is exactly 59 dollars.

Answer:

[tex]Volume = 24\ ft^3[/tex]

Step-by-step explanation:

Given [Missing from the question]

[tex]Length = 170cm\\ Width = 100cm\\ Height = 40cm[/tex]

Required

Determine the volume

This is calculated as:

[tex]Volume = Length * Width * Height[/tex]

[tex]Volume = 170cm * 100cm * 40cm[/tex]

[tex]Volume = 680000cm^3[/tex]

Convert to cubic foot [Divide by 28317 ]

[tex]Volume = \frac{680000\ ft/^3}{28317}[/tex]

[tex]Volume = 24.0138432744\ ft^3[/tex]

[tex]Volume = 24\ ft^3[/tex] --- approximated
