what’s the answer to this

Answer:

Yes

Step-by-step explanation:

The area of a square is equal to the length squared.

So, the length of one side of the original floor is √400 which equals 20.

If you increase the length by 1, the area of the dance floor is 21 squared.

21 * 21 is certainly a rational number.

Answer:

Step-by-step explanation:

I think so, yes.

The area of a square is A = s*s where s is the length of the side

s^2 = 400

sqrt(s^2) = sqrt(400)

s = 20

If you increase each dimension by one foot you get 21 * 21 for the area of the new ballroom.

The result is rational. That's because the square root was rational when you found 20.

Area = 21 * 21 = 441 which is rational.

Answer:

AB = 26

Step-by-step explanation:

BC = 36

AC = 62

AB = ?

to find ab we need to

AB + BC = AC (given)

AB + 36 = 62

AB = 62 - 36

AB = 26

Answer:

6[tex]s^{2}[/tex] + 43s + 55

Step-by-step explanation

(3s+5)(2s+11)

Distribute

3s x 2s = 6[tex]s^{2}[/tex]

3s x 11 = 33s

5 x 2s = 10s

5 x 11 = 55

Add like terms

6[tex]s^{2}[/tex] + 43s + 55

Answer:

4

Step-by-step explanation:

let y = the number

y x 5 - 24 = -44

y x 5 = -44 + 24

y x 5 = 20

y = 20/5

y = 4

Answer:

Choice 3. -4x-3<13

Step-by-step explanation:

First, you will use process of elimination and cross out any obvious wrong answers. You can see that the symbol would not be flipped yet so the "<" would be pointing  to less than. That eliminates choice 1 and 4. Now, You can observe the 3rd step and see that -4x<16, to get that, you would need a "-4x" in the equation. Number 2 is 2x so that can't be right. Therefore, the answer is choice 3. This simple process of elimination and looking for clues will help you greatly in multiple choice problems instead of solving it the hard way.

Answer:

x = [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Equate f(x) and g(x) , that is

- 3x + 4 = 2 ( subtract 4 from both sides )

- 3x = - 2 ( divide both sides by - 3 )

x = [tex]\frac{-2}{-3}[/tex] = [tex]\frac{2}{3}[/tex]

Answer:

2x+7

Step-by-step explanation:

3x +(-x) = 3x - x, so it's 2x

12 + (-5) is the same situation, just being 12 - 5, so it's 7.

putting them together leaves you with 2x+7

Answer:

2.56 gallons per minute!

Step-by-step explanation:

44.8 gallons - 32 gallons = 12.8 gallons

12.8 gallons in 5 minutes - so we need to find the unit rate (per one minute)

12.8/5 = 2.56

2.56 gallons per minute!

Answer:

(-1,-1)

Step-by-step explanation:

oh yeah thats easy it's 21 not much of a explanation needed

Answer:

8m/s

Explanation:

Given,

Distance covered (s) = 2.4 = 2.4 * 1000 = 2400m

Time taken (t) = 5 = 5 * 60 = 300

Now,

v = s/t

or, v * t = s

or, v * 2400 = 300

or, v = 2400/300

or, v = 8m/s

Answer:

(0, - 2 ) and (3, 4 )

Step-by-step explanation:

Given the equations

3y = 2(x² - 3) , that is

3y = 2x² - 6 → (1)

2x - y = 2 (add y to both sides )

2x = 2 + y ( subtract 2 from both sides )

2x - 2 = y → (2)

Substitute y = 2x - 2 into (1)

3(2x - 2) = 2x² - 6

6x - 6 = 2x² - 6 ( subtract 6x - 6 from bpth sides )

0 = 2x² - 6x ( factor out 2x from each term )

0 = 2x(x - 3)

Equate each factor to zero and solve for x

2x = 0 ⇒ x = 0

x - 3 = 0 ⇒ x = 3

Substitute these values into (2) for corresponding values of y

x = 0 : y = 2(0) - 2 = 0 - 2 = - 2 ⇒ (0, - 2 )

x = 3 : y = 2(3) - 2 = 6 - 2 = 4 ⇒ (3, 4 )

Answer:

y = -1/2x - 7

Step-by-step explanation:

y2 - y1 / x2 - x1

-6 - (-5) / -2 - (-4)

-1 / 2

= -1/2

y = -1/2x + b

-5 = -1/2(-4) + b

-5 = 2 + b

-7 = b

Answer: n=-30

Step-by-step explanation:

With what we are given in the description, we can find the missing number.

[tex]8+\frac{n}{3} =-2[/tex]

We get this equation because 8 is adding the quotient of a number and 3. A quotient of a number and 3 is written as [tex]\frac{n}{3}[/tex] because n is dividing 3. When that is added to 8, we get -2. With this equation, we can solve for n.

[tex]8+\frac{n}{3} =-2[/tex]           [subtract both sides by 8]

[tex]\frac{n}{3} =-10[/tex]                [multiply both sides by 3]

[tex]n=-30[/tex]

Now, we know that n=-30.

Answer:

aquatic environment is best fit

Answer:

Based on the data, there would likely be a very low amount of organisms performing aerobic cellular respiration at 1,000 meters as compared to the surface. This is due to the sudden drop in oxygen concentrations from 6 to 1.8 between 800-1,000 meters, while carbon dioxide increased from 44 ml/l to 49 ml/l.

The most beneficial adaptation for organisms based on the data would be anaerobic cellular respiration (without oxygen).

Step-by-step explanation:

Aerobic cellular respiration is a chemical process where oxygen is required to create energy from carbohydrates.

Answer: Part A: a square pyramid Part B: 84 square feet

Step-by-step explanation:

Part A: The shape will have a base that is a square with triangles on each of its edges that connect at a point at the top.

Part B: The amount of nylon needed is the surface area of the net. There is a square and two triangles. The square has a side length of 6 so its area will be 6*6=36 square feet. Each triangle has a base of 6 and a height of 4 so each of their areas will be [tex]\frac{6*4}{2}=12[/tex] square feet. Adding up the area of the 4 triangles and the square gives us 4*12+36=84 square feet.

Answer:

a. y = x - 2

Step-by-step explanation:

y = a.x + b

from the graph: x = 0, y = -2 --> b = -2

                          x = 2, y = 0  --> 0 = a.2 -2 --> a = 1

Answer: A solution that results in a false statement when substituted back into the original equation.

Step-by-step explanation: An extraneous solution is one that arises in a solution of equations, but which on closer inspection is not a solution to the original equation. Therefore, they imply an error in the development of the solution of the equation, so they cannot be taken as a valid solution since, when replacing the result with the missing variable, the equation does not obtain the desired result.
