What is the Anwser if a divide 33 into 2 groups so the ratio is 4 to 7
Naddika [18.5K]
You have to solve this algebraicly.
To do this set up the proportion and add x to each term.
You get 4x and 7x
Set this equal to 33
4x+7x=33
Combine like terms and get 11x=33
Divide by 11
x=3
Now go back to 4x and 7x
Multiply them by x and get 12(4×3=12) and 21(7×3=21)
One group is 12 and the other is 21.

Sara works for 40 hours a week. She attends meetings for 0.28 of the time she is working. How much time does Sara spend at meeti
Roman55 [17]

Answer:

11.2 hours or 11 hours 12 minutes

Step-by-step explanation:

In this question, we are to calculate the amount of time spent by Sara in attending meetings weekly.

In the question, we are made to understand that she attends a meeting at a rate of 0.28 multiplied by the total amount of time she works.

To get the time she attends the meeting, we only need to multiply the decimal by the number of hours she works

Mathematically that would be 0.28 * 40 = 11.2 hours per week

We might take it further to get the time in the format of hours and minutes. That would be 0.2 * 60 yo convert the hours to minutes. This gives 12 minutes .

She attends meeting 11 hours 12 minutes per week

Alenkasestr [34]

Answer:

Domain: {-4, -2, 1, 2, 4}

Range: {-4, -2, -1, 1, 4}

The relation is a function.

Step-by-step explanation:

A <u>relation</u> is any set of ordered pairs, which can be thought of as (input, output).

A function is a <em>relation</em> in which no two ordered pairs have the same first component and different second components.

Remember that a function can only take on <u>one output for each input</u>. We cannot plug in a value and get out two values.

The Vertical Line Test allows us to know whether or not a graph is actually a function.  If a vertical line intersects the graph in all places <u><em>at exactly one point</em></u>, then the relation is a function.

I did the Vertical Line Test on your given graph. As you can see from the attached screenshot, each vertical line crosses the graph only once. Therefore, the given relation is a function.

The <u><em>domain</em></u> of the given relation is the set of x-values, while the <em><u>range</u></em> is the set of y-values. You'll have to list the ordered pairs in order to determine the domain and range of the given relation.

Relation:  {(-4, -1), (-2, 1), (1, -2), (2, 4), (4, -4)}.

Domain: {-4, -2, 1, 2, 4}

Range: {-4, -2, -1, 1, 4}
