if Kyle's terrarium had a volume of 64 ft3 ,what would the edge length be?

Answers

Answer:

4 ft

Step-by-step explanation:

Volume of a cube = [tex]x^{3}[/tex] (where x equals the side/edge length)

V = [tex]x^{3}[/tex]

64 = [tex]x^{3}[/tex]

64 divided by 3 = 4 ft

Answers

Answer:

y = -3 ÷ 2x - 3

Step-by-step explanation:

As it can be seen that the line is passed by y-axis at -3.

Now we have to determine the slope

For this, use the following formula

= (x2 - x1) ÷ (y2 - y1)

At

(-2, 0), (0, -3)

So,

= (-3-0) ÷ (0+2)

= -3 ÷ 2

Now

Put in the following equation

y = mx + b.

where,

m = slope

b = y-intercept

So,

y = -3 ÷ 2x - 3

x+2/2x+3=y+1 rearrange and make x the subject

Answers

Answer:

x = y/2 - 1

Step-by-step explanation:

Solve for x:

2 x + 3 = y + 1

Hint: | Isolate terms with x to the left hand side.

Subtract 3 from both sides:

2 x = y - 2

Hint: | Solve for x.

Divide both sides by 2:

stadium already has 250 people in it at noon.If 35 people per minute enter the stadium,how many are in the stadium at 1:30 p.m. when a concert is supposed to begin?

Answers

Answer:

3,400 people

Step-by-step explanation:

First, find how many minutes are between noon and 1:30 pm

This is an hour and 30 minutes, so it will be 90 minutes

Then, multiply 90 by 35, since 35 people enter per minute

90(35)

= 3150

Then, add the 250 people that were already in it

3150 + 250

= 3400

So, there will be 3,400 people in the stadium

Answer:

3400

Step-by-step explanation:

250+35m=noon

Which step is the most efficient way to find the solution of x + 4 > -8? Answer choices: A: Add 4 to both sides. B: Subtract 4 from both sides and switch the inequality symbol. C: Substitute 1 for x and see if it works. D: Subtract 4 from both sides.

Answers

Answer:

d

Step-by-step explanation:

The most efficient step to finding the solution to the given inequality is, to subtract 4 from both sides. Option D is correct.

Given that,
To determine which step is the most efficient way to find the solution of x + 4 > -8.

What is inequality?

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

here,
Given inequality,
x + 4 > -8
Subtract 4 from both sides,
x + 4 - 4 > - 8 - 4
x > -12

Thus, the most efficient step to finding the solution to the given inequality is, to subtract 4 from both sides. Option D is correct.

6. 1.66666

Step-by-step explanation:

1.  Let's solve your equation step-by-step. ( x + 5 ) ( x − 2 ) = 0 Step 1: Simplify both sides of the equation. x 2 + 3 x − 10 = 0 Step 2: Factor left side of equation. ( x − 2 ) ( x + 5 ) = 0 Step 3: Set factors equal to 0. x − 2 = 0 or x + 5 = 0 x = 2 or x = − 5.        <—— this is for the first explanation

2. Step 1: Simplify both sides of the equation. 6 x 2 + 13 x − 5 = 0 Step 2: Factor left side of equation. ( 3 x − 1 ) ( 2 x + 5 ) = 0 Step 3: Set factors equal to 0. 3 x − 1 = 0 or 2 x + 5 = 0 x = 1 3 or x = − 5 2 Answer: x = 1 3 or x = − 5 2

<———— this is for the second explanation

3.Step 1: Factor left side of equation. ( x + 1 ) ( x − 4 ) = 0 Step 2: Set factors equal to 0. x + 1 = 0 or x − 4 = 0 x = − 1 or x      

<———- this is for the third explanation

4.Step 1: Factor left side of equation. ( 2 x + 1 ) ( x − 3 ) = 0 Step 2: Set factors equal to 0. 2 x + 1 = 0 or x − 3 = 0 x = − 1 2 or x = 3

<—————- this is for the fourth explanation

5. Step 1: Add 16 to both sides. x 2 − 16 + 16 = 0 + 16 x 2 = 16 Step 2: Take square root. x = ± 16 x = 4 or x = − 4

<—————- this is for the fith explanation

6. Step 1: Add 25 to both sides. 9 x 2 − 25 + 25 = 0 + 25 9 x 2 = 25 Step 2: Divide both sides by 9. 9 x 2 9 = 25 9 x 2 = 25 9 Step 3: Take square root. x = ± 25 9 x = 1.666667 , − 1.666667

<—————- this is for the sixth explanation

3/10 - 1/4=
3/14
3/6
1/2
1/20

Answers

Answer:

1/20

Step-by-step explanation:

3/10 - 1/4

First, convert the fractions to a common denominator:

3/10 *2/2 = 6/20

1/4 * 5/5 = 5/20

Now put them back into the equation and solve:

6/20 - 5/20 = 1/20

Another way to do this:

3/10 - 1/4

Convert the fractions into decimals:

3/10 = 0.3

1/4 = 0.25

substitute back into the equation and solve:

0.3 - 0.25 = 0.05

convert back into fractions:

0.05 = 1/20

y varies directly with x, and y=24 when x=-15. what is x when y=16? a) 10 b) -22.5 c) -10 d) -25.6

Answers

Answer:

c

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 24 when x = - 15, then

24 = - 15k ( divide both sides by - 15 )

k = [tex]\frac{24}{-15}[/tex] = - [tex]\frac{8}{5}[/tex] = - 1.6 , thus

y = - 1.6x ← equation of variation

When y = 16, then

16 = - 1.6x ( divide both sides by - 1.6 )

x = - 10 → c

They had little desire to make the world over. The world-at least their comer of it -had already been made over to their general satisfaction ....
