During a field trip , 60 students are put into equal sized groups

Answer:

[tex]\frac{4}{3}[/tex]hrs/house

Step-by-step explanation:

Rate is the amount of work done per unit of time;

  Let Cara's rate  = C

   Let Jena's rate  = J

        C + J  = 4  ------ i

Now;

  Working alone:

             Jena takes twice as long as Cara

                          J  = 2C  ---- i

How long does it take Cara to clean a house alone

           C + J  = 4

             J = 2C

        C + 2C = 4

           3C = 4

              C = [tex]\frac{4}{3}[/tex]hrs/house

Answer:

v = 0.416 m/s

Step-by-step explanation:

Give that,

Distance covered by a train, d = 50 m

Time taken, t = 120 s

We need to find the speed of a train. The formula for speed of an object is equal to the total distance covered divided by total time taken. It can be given by :

[tex]v=\dfrac{d}{t}\\\\v=\dfrac{50\ m}{120\ s}\\\\v=0.416\ m/s[/tex]

So, the speed of a train is 0.416 m/s.

Answer:

8 years

Step-by-step explanation:

The time period such that interest earned was $55.20 on an investment of $230 has a rate of 3% will be 8 years.

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific time.

Unlike compound interest, which adds the interest from the principal of prior years to determine the interest of the following year, the principal amount in simple interest remains constant.

As per the given,

Principle amount P = $230

Rate of interest R = 3 %

Interest earned = $55.20

It is known that.,

Interest earned = PRT/100

55.20 = (230 x 3 x T)/100

(55.20 x 100)/(230 x 3 ) = T

T = 8 years

Hence "The time period such that interest earned was $55.20 on an investment of $230 has a rate of 3% will be 8 years".

Answer:

the answer is d. 4x²+x-6

Step-by-step explanation:

In order to combine the fractions, they need to have the same denominator.

So, multiply each of their numerators by the denominator they need to be equivalent.

This would look like this:

3x/x+3 --> 3x(x)/x(x+3)        ---simplify this as--> 3x²/x(x+3)

x-2/x  --> (x-2)(x+3)/x(x+3)  ---simplify this as --> x²+x - 6/x(x+3)

3x                    3x(x)                                     x-2                   (x-2)(x+3)

-----      --->        -----                 and             --------   --->           ---------

x+3                   x(x+3)                                    x                        x(x+3)

now that both fractions have the same denominator, we can add their numerators.

3x² + x²+x-6 = 4x²+x -6

This should now look like this:

4x²+x -6

Answer:

None of the answers choices.

Step-by-step explanation:

Slope-intercept form is [ y = mx + b ] where m = slope and b = y-intercept.

We are given the slope, so we need to find the y-intercept.

y = 2x + b

19 = 2(5) + b

19 = 10 + b

9 = b

Fill in the formula with everything we solved for.

y = 2x + 9

Answer:

n=9

Step-by-step explanation:

7n+5=68  Subtract 5 on both sides.

    -5  -5

7n=63       Divide both sides by 7.

/7   /7

n=9

Hope this helps! Have a nice day ^^

Answer:

n = 9

Step-by-step explanation:

1) Move similar terms to one side. Here we are moving the 5 over to the side with 68 by subtracting it. We also have to subtract 5 from the other side too (what you do to one side you must do to the other)

7n + 5 = 68

     - 5   -5

      7n = 63

2) Isolate the variable. We do this by dividing the 7 from 7n. We also have to divide 7 from other other side too.

     7n = 63

     /7    /7

       n =9

Following are the solution to this question:

Step-by-step explanation:

They provide various boxes or various objects.  It also wants objects to be distributed into containers, so no container is empty.  All we select k objects of r to keep no boxes empty, which (r C k) could be done.  All such k artifacts can be placed in k containers, each of them in k! Forms. There will be remaining [tex](r-k)[/tex] objects. All can be put in any of k boxes.  Therefore, these [tex](r-k)[/tex] objects could in the [tex]k^{(r-k)}[/tex] manner are organized.  Consequently, both possible ways to do this are

[tex]=\binom{r}{k} \times k! \times k^{r-k}\\\\=\frac{r! \times k^{r-k}}{(r-k)!}[/tex]

Consequently, the number of ways that r objects in k different boxes can be arranged to make no book empty is every possible one

[tex]= \frac{r!k^{r-k}}{(r-k)!}[/tex]

Hey there! We can solve this problem by setting up the equation in slope-intercept form and changing it into standard form.

(I'm assuming that the problem meant the slope is [tex]\frac{1}{2}[/tex].)

[tex]\begin{aligned}y&=mx+b&&\smash{\Big|}&&\text{Start with slope-intercept form.}\\y&=\frac{1}{2}x+3&&\smash{\Big|}&&\text{Substitute in the known values.}\\-\frac{1}{2}x+y&=3&&\smash{\Big|}&&\text{Move the variables to the left.}\\x-2y&=-6&&\smash{\Big|}&&\text{Multiply everything by $-2$.}\end{aligned}[/tex]

Given:

Flour used to bake a cake = [tex]\dfrac{3}{5}[/tex] kg

He use [tex]\dfrac{1}{2}[/tex] kg less flour to bake some cookies.

To find:

The quantity of flour he used to bake the cookies.

Solution:

Mr. Alam use  [tex]\dfrac{3}{5}[/tex] kg kg of flour to bake and cake and use [tex]\dfrac{1}{2}[/tex] kg less flour to bake some cookies.

Quantity of flour he used to bake the cookies is

[tex]\text{Required Flour}=\dfrac{3}{5}-\dfrac{1}{2}[/tex]

[tex]=\dfrac{6-5}{10}[/tex]

[tex]=\dfrac{1}{10}[/tex]

Therefore, he use [tex]\dfrac{1}{10}[/tex] kg flour to bake some cookies.
