Hopefully this helps you

Answer:

360

Step-by-step explanation:

270 = 75% of x

270 = 0.75 × x

0.75x = 270

x = 270/0.75

x = 360

Answer: 360

Answer:

360

Step-by-step explanation:

We have, 75% × x = 270

or, 75/100 × x = 270

Multiplying both sides by 100 and dividing both sides by 75,

we have x = 270 × 100/75x = 360

If you are using a calculator, simply enter 270×100÷75, which will give you the answer.

Using exponential function concepts, it is found that it represents a decay of 0.9%.

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

In this problem, the function is:

[tex]A(t) = 9300(0.991)^{6t}[/tex]

Hence:

[tex]1 - r = 0.991[/tex]

[tex]r = 0.009[/tex]

Thus, it represents a decay of 0.9%.

Answer:

4378

Step-by-step explanation:

Step-by-step explanation:

y = 16x²

you put the x values one after the other in place of x and do the calculations.

x = -4

y = 16×(-4)² = 16×16 = 256

x = -3

y = 16×(-3)² = 16×9 = 144

x = -2.5

y = 16×(-2.5)² = 16×6.25 = 100

x = -2

y = 16×(-2)² = 16×4 = 64

x = -1.5

y = 16×(-1.5)² = 16×2.25 = 36

x = -1

y = 16×(-1)² = 16×1 = 16

x = -0.5

y = 16×(-0.5)² = 16×0.25 = 4

x = 0

y = 16×0² = 16×0 = 0

x = 0.5

y = 16×0.5² = 16×0.25 = 4

x = 1

y = 16×1² = 16×1 = 16

and so on.

36, 64, 100, 144, 256

as you can see, the y values are the same for the positive and the negative values.

because squaring a negative number is the same as squaring the same positive number. that is, because (if you remember) squaring something means to multiply that something with itself. and minus multiplied by minus is plus, as plus multiplied by plus is plus.

and that creates the symmetry around the y-axis or x = 0. everything left of the y-axis is mirrored on the right side of the y-axis (and vice versa).

Solution:

Answer: 4xy+6x+2x^2

Step-by-step explanation:

4xy-2x+2x^2+8x

we can combine the terms that only have an x (Ax for any number A)

in this case that's -2x and 8x

-2x+8x=6x

the other things can't be combined

thus you end up with

4xy+6x+2x^2

Answer:

50 players

Step-by-step explanation:

Let x be the amount of players last year and y be the amount of players this year then...

y=3x+2

y=152

We can solve this using substitution. Substitute 152 for y:

y=3x+2

152=3x+2

Subtract 2 from both sides (subtraction property of equality)

152-2=3x+2-2

150=3x

Divide both sides by 3 (division property of equality)

x=50

There were 50 players last year.

Answer:

3

Step-by-step explanation:

3 is not a factor of 16.

Is that a valid answer? lol

Hi there!

First of all, let's determine the factors of 16.

Remember, a factor is a number that a number can be evenly divided by.

Example: 5 is a factor of 10, because 10 can be evenly divided by 5.

So, the factors of 16 are:

1, 2, 4, 8, and 16.

Now, there's an infinite amount of numbers that are not factors of 16. Here are some of them:

3, 5,7,9, 10,11, 12, 13, 14, 15...

Hope it helps.

Step-by-step explanation:

Answer:

infinite number of solutions

Step-by-step explanation:

we can use the substitution method because the second equation is already solved for 'y'

we can substitute 'x-4' for the 'y' in the first equation to get:

x - (x-4) = 4

x-x+4 = 4

x-x = 0

what 'x-x=0' indicates is that there are an infinite number of values that would be solutions

Check:

if we solve the first equation for 'y' we get:

-y = -x + 4

divide all terms by -1 to get:

y = x - 4 which matches the other equation which means this two equations are equal and will create only one line

Answer:

base times height

Step-by-step explanation:

Lets say its a cube with a length of 6, a width of 6, and a height of 6. I would find the base first by multiplying the width times length, which you probably know how to do.  The base would be 36, then I would multiply it by the height which is six which would be 216.

Answer:

$1.28

Note for you:

I hope this helps!

Answer and Step-by-step explanation:

The computation is shown below;

As we know that

The simple interest is

Simple interest = Principal × rate × time

For Account A, the principal would be

2 = Principal × 3.2% × 3

So, the principal is $20.83

For account B, the principal would be

38.50 = Principal × 2.2% × 30

So, the principal is $58.33

Now the interest for both the accounts are as follows

For account 1

= $20.83 × 3.2%

= $0.67

And, for the account 2

= $58.33 × 2.2%

= $1.28

As it can be seen that the account 2 has the highest interest

The same is to be considered

You can use the circumference of the circle that the blade makes to calculate the linear velocity at the end of the blade.

The linear velocity at the end of the blade is 13571.7 inches per minute

You can think of it as if some circle is being drawn by the end of the blade and then that circle is like wheel of a bicycle and its travelling on road. Each rotation will make it cover distance equal to its circumference. Since there are 60 revolutions of the blade in each minute, thus, 60 rounds of that wheel.

The total distance in 1 minute = 60 times circumference of the circle made by the end of the blade of the lawnmower.

Since the blade is 36 inches long, it can be taken as radius of that circle.

The circumference is thus calculated as [tex]2 \times \pi \times 36 = 226.19 \: \rm inches[/tex]

Thus, linear velocity = 226.19 times 60 inches per minute = 13571.7 inches per minute

Thus,

The linear velocity at the end of the blade is 13571.7 inches per minute

Answer:

[tex]v=800(0.75)^t[/tex]

$189.84 (nearest cent)

Step-by-step explanation:

If a computer loses 1/4 of its value each year, then each year it will be 75% of the value of the previous year, since 100% - 25% = 75%.  

Therefore, we need to model this as an exponential function.

General form of an exponential function: [tex]y=ab^x[/tex]

where:

From the given information:

Substituting the values into the formula:

[tex]\implies v=800(0.75)^t[/tex]

When x = 5, t = 5

[tex]\implies v=800(0.75)^5=189.84375[/tex]

⇒ v = $189.84 (nearest cent)
