A plane seats 480. If 3/4 of the seats were full, how many people were on the plane? (Multiplying Rational Numbers)

144 inches in 4 feet

Answer:

48 inches

Step-by-step explanation:

There is 12 inches in a foot

First, you need to convert the minutes into hours, to do this you divide the minutes by 60 (the amount of minutes in an hour). Once you've gotten the value (which is 2.5), you divide that by the amount of miles drove, then you get the unit rate, or in other words      the kilometers per hour, which equals 49.6 km/h

The third set(8, 12, 10, 13, 7) has a mean of 10.

Answer:

number three 8,12,10,13,7 is it

Step-by-step explanation:

you need to add everything on number 1

like this:

9+9+9+9+9=45

45÷5=9 that is not the mean of ten

please mark the brainiest

x + y + z = 13

y = 3x - 3

z = 4x

Because we have values for y and z, we can plug them into the original equation to find the value of x.

x + 3x - 3 + 4x = 13

Combine like terms.

8x - 3 = 13

Add 3 to both sides.

8x = 16

Divide both sides by 8.

x = 2

The value of x is 2.

Because we have the exact value of x, we can insert this into each x value to find the values of y and z.

y = 3(2) - 3

y = 3

z = 4(2)

z = 8

2 + 3 + 8 = 13

In step 1, he should have added .75x to both sides.

We are given

equation of position

[tex]s(t)=(t)ln(3t)[/tex]

Calculation of velocity:

we can find derivative

[tex]s'(t)=1*ln(3t)+t*\frac{3}{3t}[/tex]

[tex]s'(t)=ln(3t)+1[/tex]

so, velocity is

[tex]v(t)=ln(3t)+1[/tex]

now, we can set it to 0

and then we can solve for t

[tex]v(t)=ln(3t)+1=0[/tex]

[tex]t=\frac{1}{3e}[/tex]

Calculation of acceleration:

we can find derivative again

[tex]v'(t)=\frac{3}{3t} +0[/tex]

[tex]v'(t)=\frac{1}{t} [/tex]

so, acceleration is

[tex]a(t)=\frac{1}{t} [/tex]

now, we can plug value of t

[tex]a(\frac{1}{3e})=\frac{1}{\frac{1}{3e}} [/tex]

[tex]a(\frac{1}{3e})=3e [/tex]..................Answer

Answer:

4 shelves are needed

Step-by-step explanation:

32 divided by 8 = 4 shelves

Answer

4 shelves

Step-by-step explanation:

If he could place 8 books on x shelves, that would equal 32 books

so

8x=32

x=4

289/200

OR

1.445

OR

1  89/200

Answer:

68 feet

Step-by-step explanation:

30 x (30-x) = 240

30-x = 8

-x = -22

x = 22

Therefore width is 30-22 = 8 feet

8+8+30+30 = 76  total for all 4 sides.

George would need 76 feet of fencing for the dog run IF he was not using his house as one side of the run.  Therefore, taking the 76 total feet that would be required to go around all 4 sides and subtracting the feet of one width (8 feet), gives a total of 68 feet.

Answer:

b

Step-by-step explanation:

He has 7 dollars left so...

We can add 7+9+12+4 to get the amount in the beginning

32$ to start with

Final answer:

To determine how much money Darryl had at the beginning of the day, we add the amounts he spent on a book, compact disc, and magazine to the money he has left, which totals $32.

Explanation:

The question involves solving a simple arithmetic problem regarding the total amount of money Darryl had at the beginning of the day, based on his expenditures throughout the day. To find out how much money Darryl had initially, we need to add up the amounts he spent on various items and then add the money he has left.

Darryl spent:

and he has $7 left.

To find the total amount Darryl had at the beginning of the day, we add up all the expenditures and the remaining amount:

$9 (book) + $12 (compact disc) + $4 (magazine) + $7 (remaining) = $32

So, Darryl had $32 at the beginning of the day.

slope-intercept form: y = mx + b where m = slope and b = y intercept

Given: slope m = 3/5 and y intercept b = -2

So equation

y = 3/5 x - 2

btw i dont think your allowed to leak that according to RSM's policy fyi

Hi!

Answer is Yes!

Explanation: This question is super easy for me. 109 is a prime number because it has not possible to factorize it. By the other words, 109 it can only divided by the 1. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie

Answer,

R = 1

Explanation,

Subtract 10 from both sides,

-3r + 10 - 10 = 15r - 8 - 10

Simplify,

-3r = 15r - 18

Subtract 15r from both sides,

-3r - 10 = 15r - 18 - 15r

Simplify,

-18r = -18

Divide both sides by -18,

-18r/-18 = -18/-18

Simplify,

R = 1

Hope this helps :-)

To solve the equation −3r+10=15r−8 for r, we first move all r terms to one side and constant terms to the other to get -18r = -18. We then divide both sides by -18 to find that r = 1.

The question is asking us to solve the equation −3r+10=15r−8 for the variable r. To do this, we first combine all terms involving r on one side of the equation and constant terms on the other side. Therefore, the equation becomes:

−3r - 15r = -8 - 10

which simplifies to:

-18r = -18.

We then divide both sides of the equation by -18 to solve for r:

r = 1.

Note that the slope-intercept form is: y = mx + b

First, set the equation as such

2x (-2x) + 3y = (- 2x) + 15

3y = -2x + 15

Isolate the y. Divide 3 from both sides

(3y)/3 = (-2x + 15)/3

y = (-2/3)x + 5

-2/3 is your slope

A

three times x = 3 × x = 3x

less 5 means subtract 5 from 3x, hence

3x - 5 → A

Answer:

[tex]3x-5[/tex]

Step-by-step explanation:

"five less than three times x"

The unknown number is x

Three times x means we multiply 3 with x

So the expression becomes 3x

5 less than 3x means we subtract 5 from 3x

To get the expression we use variables and operators like +,- . x or divide

So the final expression becomes

[tex]3x-5[/tex]

16 should be your answer, because 112 divided by 7 equals 16!

When you convert this improper fraction 112/7 to a whole number is just 16.

Okayyy, so the answer is 7.830. Adding a negative number is the same as subtracting a positive number so you can rewrite it as d-5.004=2.826, then you will add 5.004 to 2.826 and for your answer you will get 7.830.

Answer:

d=7.83

Step-by-step explanation:

Do the following

d +(-5.004)=2.826  

1) To eliminate the Parenthesis we're going to operate the plus times  -5.004:

What gives us:

d - 5.004 = 2.826

2) Let's add 5.004 to both sides to leave d alone, on ther first member:

d-5.004 +5.004= 2.826+5.004

d+0=7.830

d=7.83

Alright, let's break this down:

1. First, we will solve the addition problem on the left, which is 6.4 plus 0.92. When you add these two numbers together, you will get 7.32.

2. Secondly, we will solve the subtraction problem on the right, which is 15.74 minus 2.64. When you subtract these two numbers, you will find that the result is 13.1.

So the answer to our problem is (7.32, 13.1).

quintic means degree of 5.

a negative quintic would be: f(x) = -x⁵ +              

an example with one real zero could be: -x⁵ + x³ + x + 3   (see attachment)

Well let's start with y = -x^5 and y = - x^5 +1

The graph looks like the one on the right for these two.  The red one is y = - x^5 and the blue one is y = - x^5 + 1

See below on the right

You can tell that these two are correct because there is only 1 x axis intercept for each of them.  That means there is only 1 real solution which is what you are calling for.

Another one could be something like

y = -(x - 5)(x^2 + 2)(x^2 + 3)

The graph of that is on the left.

Remark

Velocity is speed that has a direction. So the answer excludes both being true. C and D are both incorrect for the same reason: you cannot have both together when a direction is given.

Speed has no direction.

Answer: B  Velocity has direction and a magnitude of speed.

As given,

Current value = [tex]1.2\times10^{7}[/tex] dollars

Twenty years ago value was = [tex]9.6\times10^{5}[/tex] dollars

suppose x times the investment has increased, so,

[tex]9.6\times10^{5}[/tex]*x=[tex]1.2\times10^{7}[/tex]

x = [tex]\frac{1.2\times10^{7}} {9.6\times10^{5}}[/tex]

this gives x = 12.5 times.

Hence, option B is the correct answer.

The answer is

[tex]\sqrt{x}[/tex]

because,

[tex]a^{x/n} = \sqrt[n]{x}[/tex]

Hey there!

When you write an equation in function notation, one side of the equation is, "f(x)".

You can replace x with another variable such as n if you are using a different one.

f(x) takes the place of y in an equation.

For example, the equation y = 3x + 2 in function notation is f(x) = 3x + 2.

Hope this helps!

ANSWER

[tex]5N^2=3^{2} \times 5^{5} \times x^{6}[/tex]

EXPLANATION

[tex]N=3\times5^2 \times x^3[/tex].

[tex]5N^2=5(3\times5^2 \times x^3)^2[/tex]

Recall this property of exponents;

[tex](a^m)^2=a^{m} \times a^m[/tex]

So our product becomes;

[tex]5N^2=5(3\times5^2 \times x^3) \times (3\times5^2 \times x^3)[/tex]

[tex]5N^2=5\times 3\times 3 \times 5^2 \times 5^2 \times x^3 \times x^3[/tex]

[tex]5N^2=3\times 3\times 5 \times 5^2 \times 5^2 \times x^3 \times x^3[/tex]

Recall this law of exponents:

[tex]a^m \times a^n =a ^{m+n}[/tex]

[tex]5N^2=3^{1+1} \times 5^{1+2+2} \times x^{3+3}[/tex]

[tex]5N^2=3^{2} \times 5^{5} \times x^{6}[/tex]
