A research company found that 11% of the people that they called agreed to participate in a survey.
If the company called 196 people, how many would be expected to participate in the survey?

Answer:

x = -1

y = 7

Step-by-step explanation:

We have a system of equations and are asked to solve using substitution.

y = -7x

2x - y = -9

Since we have an equation for y by itself, we can plug the first equation into the second.

2x - (-7x) = -9

Distribute :

(-(-7x))

2x + 7x = -9

Add like terms :

9x = -9

Divide 9 by both sides to get x :

x = -1

Now that we know x, we can plug it into the first equation to find y :

y = -7(-1)

y = 7

Answer:

x=2, y=-2

(2, -2)

Step-by-step explanation:

x + y = 0

3x - 2y = 10

3x - 2(0 - x) = 10                  ( 2(0 - x) = -2x )

3x - (-2x) = 10                      ( y = -x )

3x + 2x = 10

5x = 10

x = 2

Answer:

It can hold up to [tex]1.256ft^3[/tex] of waste

Step-by-step explanation:

Given

[tex]D = 1.5ft[/tex] -- Diameter

[tex]h = 1.6ft[/tex] -- height

Required

Determine the amount of waste it can hold

This simply means that we calculate the volume of the cylindrical container.

And this is calculated using:

[tex]Volume = \pi r^2h[/tex]

Where

[tex]\pi = 3.14[/tex]

and

[tex]r = \frac{D}{2}[/tex]

[tex]r = \frac{1.5}{2}[/tex]

[tex]r = 0.75[/tex]

So, we have:

[tex]Volume = 3.14 * 0.5^2 * 1.6[/tex]

[tex]Volume = 1.256ft^3[/tex]

Hence, it can hold up to [tex]1.256ft^3[/tex] of waste

The amount of waste a cylinder can hold nearest to the whole number is 3 cubic feet.

A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.

A cylindrical hazardous waste container has a diameter of 1.5 feet and a height of 1.6 feet.

The amount of waste a cylinder can hold will be given by the volume of the cylinder.

The volume of the cylinder will be

[tex]\rm Volume = \dfrac{\pi}{4} d^2 h[/tex]

We have

d = 1.5 ft

h = 1.6 ft

Then

[tex]\rm Volume = \dfrac{\pi}{4} * 1.5^2 * 1.6\\\\\rm Volume = \dfrac{\pi}{4} *2.25 * 1.6\\\\\rm Volume = 2.82 \approx 3 \ ft^3[/tex]

To find the slope-intercept form

 --> we need to find the slope

 --> we need to find the y-intercept

         The point at which the x-coordinate equals zero

Let's find the slope

 --> let's pick any two pair of points

       (0, -3) & (6, 0)

           (x1, y1) ==> (0, -3)

           (x2, y2) ==> (6, 0)

 --> our slope formula is:

           [tex]\text{Slope}=\dfrac{0--3}{6-0}=\dfrac{3}{6}=\dfrac{1}{2}[/tex]

Let's find our y-intercept

Step-by-step explanation:

Answer:

Ratio: 3:2

LN = 18

Step-by-step explanation:

"similar" means that all the angles are the same and the sides were all increased by the same proportion.

Thus, we know that MN/YZ = LM/XY = NL/ZX

First, we need to find the ratio. To do this, we write MN/YZ as a fraction, and simplify.

MN/YZ = 15/10 = 3/2

(If you want, you can double check this using LM nd XY. 8 * 3/2 = 12, so this is correct)

To find the missing side, we simply multiply XZ by 3/2.

12 * 3/2 = 18, so LN = 18.

Answer:

r < -18

Step-by-step explanation:

-5r+2r is greater than 54 can be written symbolically as:

-5r+2r > 54

Combining the r terms, we get:

-3r > 54

Solving this result for r requires reversing the direction of the inequality sign:

r < -54/3, or r < -18

Answer:

r < -18

Step-by-step explanation:

[tex]-5r+2r > 54\\\\\rightarrow \text{Greater Than - } >\\\\\\\text{Combine the Like Terms}\\\\-5 + 2 = -3\\\\\text{So:}\\\\-5r+2r=-3r\\\\\\-3r>54\\\\\text{Divide by -3: }\\\\\frac{-3r>54}{-3}\\\\\boxed{r<-18}\\\\[/tex]

We switch the inequality sign if we multiply or divide both sides of the inequality by a negative number.

.............................................................................................

If home team had 4 three-pointers, 10 two-pointers, and 6 free throws. The visiting team scored 5 three-pointers, 8 two-pointers, and 5 free throws. Then Home team scored more points.

Addition is a process of combining two or more numbers.

For Home team,

4 three-pointers,

10 two-pointers, and

6 free throws

4+10+6

Four plus ten plus six

For visiting team

5 three-pointers,

8 two-pointers, and

5 free throws

5+8+5

Five plus eight plus five
