B

Step-by-step explanation:

21/8 = 2.6

2.6 = 3 rounded

Answer: B. (-2, 18),  (0, 10),  (2, 2)

STEP 1:  f(18)= 10 - 4 * 18= 10 - 72= -62... (18, 62)

STEP 2:  f(-18)= 10 - 4 * -18= 10 - (-72)= 82... (-18, 82)

STEP 3:  f(2)= 10 - 4 * 2=10- 8= 2... (2, 2)

Answer:

the value of a1 in a geometric series is 12 if i remember correctly.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Since dividing any term by the previous term is constant this is a geometric sequence. In this case the common ratio is 18/6=54/18=3 and the first term a1=6

So a1=6 and r=3

Answer:

x =7

Step-by-step explanation:

Let's solve your equation step-by-step.

4 ( 2x − 3 ) = 6x + 2

Step 1: Simplify both sides of the equation.

4 ( 2x − 3 ) = 6x + 2

( 4 ) ( 2x ) + ( 4 ) ( −3 ) = 6x + 2 ( Distribute )

8x + −12 = 6x + 2

8x − 12 = 6x + 2

Step 2: Subtract 6x from both sides.

8x − 12 − 6x = 6x + 2 − 6x

2x − 12 = 2

Step 3: Add 12 to both sides.

2x − 12 + 12 = 2 + 12

2x = 14

Step 4: Divide both sides by 2.

2x  / 2  =  14  / 2

x = 7

Answer:

Equation: y = 8x + 56

After 5 minutes, the volume of the water was 96 gallons

Step-by-step explanation:

Use y = mx + b to create the linear equation, where m is the slope and b is the y intercept.

Since the water flows in at 8 gallons per minute, 8 will be the slope. The variable x will represent the number of minutes.

There are already 56 gallons of water in the tank, so b will be 56.

Plug in these values into the equation:

y = 8x + 56

So, the linear equation is y = 8x + 56

Using this, plug in 5 as x to find the volume of the water in the sink after 5 minutes:

y = 8x + 56

y = 8(5) + 56

y = 40 + 56

y = 96

So, after 5 minutes, the volume of the water was 96 gallons

Answer:

The measure of the sum of interior angles of a 11-gon is [tex]1620^{o}[/tex].

Each interior angle is approximately [tex]147.273^{o}[/tex].

Step-by-step explanation:

A convex polygon has the measure of each interior angles to be less than [tex]180^{o}[/tex].

But,

sum of interior angles of polygon = (n - 2) x [tex]180^{o}[/tex]

where n is the number of sides of the polygon.

For a convex 11-gon, we have;

sum of angles of a 11-gon = (11 - 2) x [tex]180^{o}[/tex]

                                         = 9 x [tex]180^{o}[/tex]

                                         = [tex]1620^{o}[/tex]

Sum of angles of a 11-gon = [tex]1620^{o}[/tex]

To check: convex polygons' interior angles are less than [tex]180^{o}[/tex].

so that,

each interior angle of 11-gon = [tex]\frac{1620}{11}[/tex]

                                        = [tex]147.273^{o}[/tex]

Answer:    0.25 as a decimal

Answer:

0.25

Step-by-step explanation:

You can think of fractions as smaller increments of money.

2/4=0.5

3/4=0.75

Bob has a dollar bill. He uses 1/4 of it to buy a coupon.

Imagine this happening:

1$

Uses 1/4

So... Let's look at what I've given you.

2/4=0.5

3/4=0.75

Well, let's stretch some things a liiiiitle bit.

Bob has a dollar bill blah blah...

We get to 1/4.

Le's make that 2/4.

2/4 is 0.5

So... By stretching the truth

We can infer that

If we put 1/4 back

(Oh no now the word problem creators are mad at me ;) lol)

Anyways, we can infer that by putting 1/4 back

That since 3/4 is 0.75

Then what's connected to 0.5 and 0.75?

The answer, my friend,

Is 0.25

Answer:

16

Step-by-step explanation:

1) to find perimeter we multiply length and breadth so to find breadth we divide the perimeter by the length. which means, 120 divided by 45 and its 62.5 so the answer for the 1st question is 62.5

2. if we multiply length with breadth to find perimeter, just like the first one we divide the perimeter by the breadth. which means, 250 divided by 50 and it will be 5

The first one I'll do is Physics because you know the amount of girls and total amount of students. Use the equation x+19=33. Note that x is the amount of boys we are trying to find. All you need to do is simply subtract 19 from both sides to get x alone.

                                             x + 19 = 33

                                                  -19   -19

                                             x         = 14

For the total that's going up and down, you can do this same process again, but just using x for girls instead of boys. Your equation should look like 47+x=80. Once again, subtract 47 from both sides.

                                             47 + x = 80

                                             -47        -47

                                             x         =  33

Now you can find whole row for boys. This equation will be a little longer, but it's still pretty easy. 18+x+14=47 is what we will be using. We first will need to combine like terms (the 18 and 14), then subtract it off from both sides to get x alone.

                                             18 + x + 14 = 47

                                                    x + 32 = 47

                                                        -32   -32

                                                     x         = 15

Moving onto the biology column, we'll be using the equation 15+x=21

                                             15 + x = 21

                                            -15        -15

                                             x         = 6

Now we can find out the girls column with this equation: x+6+19=33

                                           x + 6 + 19 = 33

                                           x + 25      = 33      

                                               -25         -25

                                                     x      = 8

Lastly, we can find the chemistry column by just adding 18+8 to get 26.

The sum of a rational number and an irrational number is irrational

Step-by-step explanation:

By definition, an irrational number in decimal form goes on forever without repeating (a non-repeating, non-terminating decimal). By definition, a rational number in decimal form either terminates or repeats. If you add a non-repeating, non-terminating decimal to a terminating decimal, you still have a non-repeating, non-terminating decimal. If you add a non-repeating, non-terminating decimal to a repeating decimal, you will no longer have a repeating decimal.

Answer:

What is the question?

Step-by-step explanation:

Answer: 19

Step-by-step explanation:

1) You combine like terms with all the angles

Ex. 2x + 15 + 9x - 3 + 77 + 8x + 8 + 13x + x - 4, which equals 33x + 93

2) You set up an equation using the formula for the sum of the interior angles

Ex. 33x + 93 = 180(n - 2)

3) Since a hexagon has 6 sides, n is 6

Ex. 33x + 93 = 180(6 - 2)

4) Solve like a regular equation

Ex. 33x + 93 = 180(6 - 2)

33x + 93 = 720

- 93 = - 93

33x = 627

- Divide 627 by 33

x = 19
