Pls answer-

Answer:

V = 16x²

Width = 12in

Height = 12in

Step-by-step explanation:

Volume of the box is expressed as;

V = Length *Width * height

Given

Length = 16in

Width = x

Height = x

The volume of the box will be expressed as;

V = 16 * x * x

V = 16x² (This gives the required equation)

To get x:

We are given

V = 2304in³

Substitute;

2304 = 16x²

x² = 2304/16

x² = 144

x= √144

x = 12

Hence the width and the height are both 12inches since they are the same.

Step-by-step explanation:The race is 111.6 m long.

8 hurdles spaced 12.3 m apart means 7 spaces that are 12.3 m in length; 7*12.3 = 86.1

Add to this the distance to the first hurdle and the distance from the last hurdle:

86.1+15+10.5 = 111.6 m

Answer:

1 hot dog costs $3.50

Step-by-step explanation:

Represent Hot dog with x and Hamburger with y

Gregory's purchase:

[tex]5x + 2y = 27[/tex] --- (1)

Hart's purchase:

[tex]3x + 4y = 29.5[/tex] ---- (2)

Required

Find x

To do this, we'll make use of the elimination method of solving simultaneous equation.

Start by multiplying (1) by 2

2 * ([tex]5x + 2y = 27[/tex])

This gives:

[tex]10x + 4y = 54[/tex] ---- (3)

Subtract (2) from (3)

[tex]10x + 4y = 54[/tex]

- ([tex]3x + 4y = 29.5[/tex])

-------------------------

[tex]7x = 24.5[/tex]

Solve for x

[tex]x = \frac{24.5}{7}[/tex]

[tex]x = 3.5[/tex]

Hence:

Magnitude of claimed earthquake = 10.363 (Approx)

Step-by-step explanation:

Magnitude of claimed earthquake = log√133,680 +  7.8

Magnitude of claimed earthquake = [1/2] log 133,680 +  7.8

Magnitude of claimed earthquake = 2.563 +  7.8

Magnitude of claimed earthquake = 10.363 (Approx)

Step-by-step explanation:

A copy machine can copy a report in 30 mins. When a second copy machine is used at the same time, the copying can be sone in 18 min. How long would it take the second copu machine to do the copying alone?

i have:

x=30

x+y=18

that would be -12..not right?

The time taken that it take the second copy machine to do the copying alone should be considered as the 11.25 minutes.

Let we assume x be the time required at the time when using both machines.

Let us assume the completed job = 1

we know that

copy machine 1 will do [tex]x/30[/tex] of the job

and

copy machine 2 will do [tex]x/18[/tex] of the job

So, it can be like

[tex]\frac{x}{30} + \frac{x}{18} = 1[/tex]

So,

18x + 30x = 540

48x = 540

x = 11.25 minutes

hence, The time taken that it take the second copy machine to do the copying alone should be considered as the 11.25 minutes.

Answer:

B

Step-by-step explanation:

Because if you will divide the ratio 4:12 by three- we will get a ratio 1:3. Then we need the last 3 in the ratio 1:3 become a 9. For this we need to multiply it by 3= 1:3 *3= 3:9. This is only 3/4 of whole of recipe.

Answer: Choice A)

Amelia is correct. She needs 3 cups of sugar because the ratio 3:9 is equivalent to 4:12

=======================================================

Explanation:

It might help to think of the ratio 4:12 as the fraction 4/12. Dividing both parts by 4 leads to 1/3.

Similarly, the ratio 3:9 becomes 3/9 which reduces to 1/3.

This shows that 4/12 = 3/9, so the ratios 4:12 and 3:9 are the same.

------------

Another way to show two fractions are equal is to do the steps below

4/12 = 3/9

4*9 = 12*3 ... cross multiply

36 = 36

Since the last equation is true, the first equation must be true.

-------------

Here's another way to see Amelia is correct.

So we know that 4 cups of sugar go with 12 cups of flour. This forms the fraction 4/12.

We also know that she has 9 cups of flour. Let's say we don't know how much sugar she needs, so we'll call this x. We have x cups of sugar go with 9 cups of flour. This forms the fraction x/9.

Equate the two fractions and solve for x

4/12 = x/9

9*4 = 12*x ... cross multiply

36 = 12x

12x = 36

x = 36/12 ... divide both sides by 12

x = 3

She needs 3 cups of sugar

The steps in this section are very similar to the steps in the last section.

4 z ^3 √ y / x ^2 y

Answer:

y=2x+2

Step-by-step explanation:

Answer: y = 2x

Step-by-step explanation:

y=mx+b

m is the slope. so if the slope is 2 we can fill in 2 for m.

y = 2x + b

now we are going to plug in the point they gave us (1, 2) to find b.

1 is the x coordinate of the point and 2 is the y coordinate. so we put 1 in for x and 2 in for y.

2 = 2(1) + b

2 = 2 + b

b = 0

so our equation is y = 2x + 0, or y = 2x

Answer:

x=−12/5

Step-by-step explanation:

2(1.5x−2)=−0.5(−4x−32)

Step 1: Simplify both sides of the equation.

−2(1.5x−2)=−0.5(−4x−32)

(−2)(1.5x)+(−2)(−2)=(−0.5)(−4x)+(−0.5)(−32)(Distribute)

−3x+4=2x+16

Step 2: Subtract 2x from both sides.

−3x+4−2x=2x+16−2x

−5x+4=16

Step 3: Subtract 4 from both sides.

−5x+4−4=16−4

−5x=12

Step 4: Divide both sides by -5.

−5x−5

=12/−5

x=−12/5

Step-by-step explanation:

They need to sell 50 tickets.

Given

The drama club at Creative High School is putting on a performance to raise money for new costumes.

Since they do not have costumes, they will pay $110 to rent costumes.

They plan on charging $5.50 per ticket.

We have to determine

The equation can be used to find the number of tickets, t, they need to sell in order to raise $275.

The charger per ticket is $5.50.

Therefore,

The equation can be used to find the number of tickets, t, they need to sell in order to raise $275.

[tex]\rm t = \dfrac{Amount\ of \ tickets}{Price \ of \ ticket}\\\\t = \dfrac{275}{5.50}\\\\t =50[/tex]

Step-by-step explanation:

"When x is zero in a direct variation equation y will also be zero. ... Equations of the form y = kx + b where b is a number other than zero are not direct variation equations because when x is zero in any of these y is not zero. Normally direct variation equations are written as y = k•x or just y = kx."

Answer:

Step-by-step explanation:

If mark uses 19 gallons to travel 399 miles, that means he was able to travel 21 miles per gallon.

We get this by taking 399 divided by 19.

So if mark travels on 9 gallons of gas and goes 21 miles per gallon, he will have traveled 189 miles.

We get this by taking 21 times 9
