Help please and thanks ​

Answer:

in 1 hr martha finishes 1/8th of the room

in 1hr jaime finishes 1/4th of the room

combined in 1hr they can finish (1/8 + 1/4) = 3/8th of the room.

for painting the whole room both of them together it takes the 8/3 hrs = 2.67hr

Step-by-step explanation:

Given

5x + 7 < - 23

Subtracting 7 from both sides

5x + 7 - 7 < - 23 - 7

5x < - 30

Dividing both sides by 5

5x / 5 < - 30 / 5

x < - 6

Hope it will help :)

Answer: x = 14/5

​

Step-by-step explanation:

1. Add 7  to both sides.

5x=7 +7

5x=7+7

Simplify  7 +7  to  14

5x = 14

5x=14

Divide both sides by 5

x =14/5

x = 14/5

Hoped this help <3 !

Answer:

It's false

Step-by-step explanation:

I took the quiz

Answer:

x = 2 and x = -7

Step-by-step explanation:

To find y = 0, so you need either x - 2 =0 or x + 7 =0, so x can be 2 or -7.

Answer:

Step-by-step explanation:

ratio of 216 : 64

bigger is 20 inches

so divide 20 by 216... to find the unit.. then multiply that by 64 to find the size of the other

20/216 = 0.0925925

0.0925925 * 64 =5.9259"

so about 6 inches

Step-by-step explanation:

[tex]12x+8y=-16\\[/tex]

We have to isolate y on one side. Look below for the full explanation.

[tex]12x+8y+16=0\\12x+16=-8y\\-16-12x=8y\\-2-3/2x=y\\y=-\frac{3}{2} x-2[/tex]

There you go!

Answer:

46

Step-by-step explanation:

Since two of the arc measure 161 and 107, we can find the other two by finding a number that will equal it to 180.

[tex]161 + 19 = 180[/tex]

[tex]107 + 73 = 180[/tex]

19 and 73 are the missing arcs.

We then apply intersecting secants theorem,

[tex] \frac{19 + 73}{2 } = 46[/tex]

46 is the answer

Answer:

1=x and 2=y

Step-by-step explanation:

Answer:

HOPE THIS HELPS

Step-by-step explanation:

The area = length * Width.

We know the width = X+6 inches and Area = x^3+3x^2–18x.

This problem can be solved just by dividing the area by width and we get a quotient as X^2–3x.

So the length is x^2–3x inches.

The length of the rectangle is [tex]\rm x(x-3)[/tex].

Given

The area of the rectangle = [tex]\rm x^3+3x^2-18x[/tex] square inches

The width of the rectangle = x + 6 inches

The area of the rectangle is equal to the product of length and width of the rectangle.

Let the length of the rectangle be L.

The area of the rectangle is given by;

[tex]\rm Area \ of \ the \ rectangle =Length \times Width\\\\[/tex]

Substitute all the values in the formula;

[tex]\rm Area \ of \ the \ rectangle =Length \times Width\\\\\rm x^3+3x^2-18x= L \times (x+6)\\\\L=\dfrac{ x^3+3x^2-18x}{x+6}\\\\L = \dfrac{ x(x+6)(x-3)}{x+6}\\\\ L = x (x-3)[/tex]

Hence, the length of the rectangle is [tex]\rm x(x-3)[/tex].

Answer:

1.68

Step-by-step explanation:

Answer:

1.68

Step-by-step explanation:

Answer:

Step-by-step explanation:

Solving

5x + -2y = 12

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2y' to each side of the equation.

5x + -2y + 2y = 12 + 2y

Combine like terms: -2y + 2y = 0

5x + 0 = 12 + 2y

5x = 12 + 2y

Divide each side by '5'.

x = 2.4 + 0.4y

Simplifying

x = 2.4 + 0.4y

Answer:

Step-by-step explanation:

Remark

The way this is worded, it sounds like it is a horizontal distance. However by the marking it looks like they want the hypotenuse. Life can be very confusing sometimes.

The angle of the triangle that you need to know is the one on the right. The line of sight line is parallel to the base of the triangle. So the angle on the right is 8 degrees by the Z theorem.

Solution

Sin(8) = 1817 / x           Multiply both sides by x

x*sin(8) = 1817             Divide by sin(8)

x = 1817/sin(8)

sin(8) = 0.1392

x = 1817/0.1392

x = 13055.7

Note

Watch how you do this. I would put it into your calculator as

1817

÷

sin(8)

=

If you use the rounded answer I gave for sin(8), you might get it wrong. This is a big distance and you should just use the exact number you get for sin(8).

Answer:

There are no vertical asympotes for this rational function.

Step-by-step explanation:

For rational functions, a vertical asymptote exists for every value of the independent variable such that function become undefined, that is, such that denominator is zero. Let be the following rational function:

[tex]C(p) = \frac{25000\cdot p}{100-p}[/tex], [tex]0\le p < 100[/tex]

There is a vertical asymptote for this case:

[tex]100-p = 0[/tex]

[tex]p = 100[/tex]

Which is out of the interval given to the rational function. Hence, we conclude that there are no vertical asympotes for this rational function.
