First, convert each width into inches by multiplying the feet by 12 and adding the inches. This leaves you with a dresser of 33 inches, 70 inches, and 54 inches. Add these together to get the total length of 157. To convert this back into feet and inches, find the highest multiple of 12 that goes into 157. This can be found by listing all multiples of 12. (12, 24, 36...) The greatest multiple that is less than 157 is 156 (12x13). This gives you 13 feet and a remainder of 1 inch. Otherwise, you can add the feet and add the inches to get 11 feet 25 inches, then find the multiple of 12 that fits into 25 (2x12=24) to get the answer anyway. Either way works just as well as the other, it is just what you prefer. Hope this helps!

A gym membership at one gym costs $10 every month plus a one-time membership fee of $15, and a gym membership at another gym cos

Minchanka [31]

Answer: Let us assume that the number of months after which

the gym memberships will cost the same = x

Then

15 + 10x = 40 + 4x

10x - 4x = 40 - 15

6x = 25

x = 25/6

= 4 1/6

So the membership fee of both the gyms will become same after 4 1/6 months. You can also consider that as after 5 months the membership fees of both the gyms will become same. I hope the procedure is not very complicated for you to understand.

Step-by-step explanation: Hope this helps!!

Please help!<3 tysm if u helped

Vilka [71]

Answer:

x = 0 1 -1 -2

y = -3 -4 -2 -1

Step-by-step explanation:

equation : 3y+9x = -9

when x = 1

3y+3x = -9

or, 3y + 3×1= -9

or, 3y+3=-9

or, 3y = -12

so, y = -4

Again

Let's suppose x as -1

3y+3x= -9

or, 3y+ 3×-1 = -9

or, 3y-3 = -9

or, 3y = -6

y = -2

Let's suppose x as -2 now,

3y+3x = -9

3y+3×-2 = -9

or, 3y-6 = -9

or, 3y = -3

so, y = -1

Point p(a,b) is in the first quadrant on the graph of the line x+y=4. A triangular region is shown on the diagram. What is the m

Gala2k [10]

Answer:

The maximum area of the triangular region is 2 square units

Step-by-step explanation:

we know that

The area of the triangular region is equal to

$A=\frac{1}{2}(x)(y)$ -----> equation A

where

x is the x-coordinate of point P

y is the y-coordinate of point P

we have

The equation of the graph of the line is

$x+y=4$

$y=-x+4$ -----> equation B

substitute equation B in equation A

$A=\frac{1}{2}(x)(-x+4)$

$A=-\frac{1}{2}x^2+2x$

This is a vertical parabola open downward (the leading coefficient is negative)

The vertex represent a maximum

The y-coordinate of the vertex represent the maximum area of the triangular region

Find the vertex

Convert the quadratic equation in vertex form

Factor -1/2

$A=-\frac{1}{2}(x^2-4x)$

Complete the square

$A=-\frac{1}{2}(x^2-4x+4)+2$

Rewrite as perfect squares

$A=-\frac{1}{2}(x-2)^2+2$

The vertex is the point (2,2)

The maximum area is the y-coordinate of the vertex

The maximum area of the triangular region is 2 square units

Find the coordinates of point P for the maximum area

x=2 (x-coordinate of the vertex)

Find the y-coordinate of point P

substitute in equation B

y=-2+4=2

The coordinates of point P for the maximum area is P(2,2)
