<em><u>Fractions</u></em><em><u> are integers that have both a numerator and a denominator. </u></em>They are represented as;  \frac{x}{y}

Where:

<em>x = Numerator</em>

<em>y = Denominator.</em>

<em />

To solve the above question, we would be applying the operations of the addition of fractions.

It will take both of them  27\frac{3}{11}  hours if they worked together.

From the question,

Nyesha takes 50 hours a week to render services to her customers.

Shantese takes 60 hours a week to do the same amount of work.

Let us represent the number of hours it will take them both to decorate the room working together as "T"

Hence,

1/T = 1/50 + 1/60

Lowest Common Denominator for (50, 60 ) = 300

Hence,

1/T = 6 + 5 / 300

1/T = 11/300

Find the reciprocal of both sides

T = 300/11 hours

T = 27\frac{3}{11} <u>hours</u>

Therefore, it will take them both of them 27\frac{3}{11} hours in they both work together.

Please explain how you got your answer!!! The dot plots below show the ages of students belonging to two groups of salsa classes
Rudik [331]

Answer:

Group b most likely has a lower mean age of salsa students

Step-by-step explanation:

Arithmetic Mean of the data is the average of a set of numerical values, calculated by adding them together and dividing by the number of terms in the set.

Here we are given with two groups that are Group A and Group B

both having total number of students = 20

Here the mean age of the data is addition of the all ages of different students divided by total number of students.

For group a

total age of the group = 3 × 5 + 4 × 10 + 6 × 17 + 4 × 24 + 3 × 29

= 15 + 40 + 102 + 96 + 87

=340

The mean age of salsa students= 340 ÷ 20 = 17

For group b

total age of the group = 6 × 7 + 3 × 10 + 4 × 14 + 5 × 16 + 2 × 21

= 42 + 30 + 56 + 80 + 42

=250

The mean age of salsa students= 250 ÷ 20 = 12.5

So the group b most likely has a lower mean age of salsa students

Solve for x<br> Logx-log(x+13)=1<br><br> Step by step explanation please
Lostsunrise [7]

Answer:

Step-by-step explanation:

Applying logarithm rule

Log A - Log B= Log(A/B). Division rule

Now, Logx-log(x+13)=1

Log(x/(x+13))=1

Assume that the log is a natural log whose base is 10.

Then apply logarithm law

Log10 base 10=1

Comparing this to Log(x/(x+13))=1

This implies that

x/(x+13)=10

x=10(x+13)

x=10x+130

x-10x=130

-9x=130

x=130/-9

x=-14.444

7x = -67 - 11v<br> 5x = -73 - 11v
Burka [1]

Answer:

x = 3, v = -8

Step-by-step explanation:

Substitute x.

\frac{-67-11v}{7}

[5 • \frac{-67-11v}{7} = -73 - 11v]

Isolate v.

5 \frac{-67-11v}{7} = -73 - 11v

v = -8

Substitute v.

x = \frac{-67-11(-8)}{7}

x = 3
