Answer:

12. 10/3, which simplifies to 3 1/3

13. 5/6

Step-by-step explanation:

The equation for best represents y, the total cost of x pounds of lean ground beef is y = 7.25x.

Given that,

Lean ground beef costs $7.25 per pound.

The total cost of x pounds of lean ground beef.

We have to determine,

The equation which represent y.

According to the question,

Lean ground beef costs $7.25 per pound.

The total cost of x pounds of lean ground beef.

The equation for representation the total cost y of x pounds is written as.

Total cost of pounds = Lean ground beef costs $7.25 per pound × cost of x pounds of lean ground beef.

The equation for total cost of y of x pounds,

y = (7.25).(x)

y = 7.25x

Hence, The equation for best represents y, the total cost of x pounds of lean ground beef is y = 7.25x.

Answer:

8190 ways

Step-by-step explanation:

Given

[tex]Teachers = 6[/tex]

[tex]Students = 15[/tex]

Selection

[tex]Students = 4[/tex]

[tex]Teachers = 5[/tex]

Required

Number of ways of selection

4 students can be selected from 15 students in:

[tex]Students= ^{15}C_4[/tex]

Similarly.

5 teachers can be selected from 6 teachers in:

[tex]Teachers= ^{6}C_5[/tex]

So, the required number of selection is:

[tex]Selection = ^{15}C_4 * ^6C_5[/tex]

Apply combination formula:

[tex]Selection = \frac{15!}{(15-4)!4!} * \frac{6!}{(6-5)!5!}[/tex]

[tex]Selection = \frac{15!}{11!4!} * \frac{6!}{1!5!}[/tex]

[tex]Selection = \frac{15*14*13*12*11!}{11!*4*3*2*1} * \frac{6*5!}{1*5!}[/tex]

[tex]Selection = \frac{15*14*13*12}{4*3*2*1} * \frac{6}{1}[/tex]

[tex]Selection = \frac{32760}{24} * 6[/tex]

[tex]Selection = 1365 * 6[/tex]

Answer:

1/2cup

as if 3and1/2cup is divided into 4people then in every one will get half cup.

Answer:

Each person gets [tex]\frac{7}{8}[/tex] cup of pudding.

Step-by-step explanation:

The problem is essentially asking;

[tex]3\frac{1}{2}[/tex] ÷ 4

(4 because the pudding has to be divided amongst Regina and her 3 friends, hence 4 people)

To divide fractions, first one has to convert from improper fractions to mixed numbers;

[tex]\frac{7}{2}[/tex] ÷ 4

Next, one has to reciprocate the second fraction, since the second number is an integer, one simply has to put the number as the denominator, and set the numerator to 1.

[tex]\frac{7}{2}[/tex] * [tex]\frac{1}{4}[/tex]

Now, one has to perform the multiplication, simply multiply the numerators and denominators together (there is no way of simplifying in this problem);

[tex]\frac{7}{8}[/tex]

Each person gets [tex]\frac{7}{8}[/tex] cup of pudding.

Answer:

We conclude that the initial value of the function is 6.

Hence, option D is correct.

Step-by-step explanation:

The initial value of the function can be determined by setting x = 0 and determining the corresponding y value.

In other words, the initial value is basically the y-intercept of the graph.

It is the output value when the input value x = 0.

Given the graph, it is clear that:

at x = 0, y = 6

Thus, at x = 0, the value of y is 6.

i.e. the y-intercept b = 6.

Therefore, we conclude that the initial value of the function is 6.

Hence, option D is correct.

Answer:

6

Step-by-step explanation:

The initial value is the y-intercept or where the line crosses the y axis.

Answer:

y = -2/3x + 4/3

Step-by-step explanation:

If two lines are perpendicular, the product of their slopes is -1

comparing what we have with the general form;

y = mx + b

The slope of the given equation is 3/2

To get the slope of other;

3/2 * m = -1

3m = -2

m = -2/3

So we want to write the point-slope equation

y-y1 = m(x-x1)

y-2 = -2/3(x + 1)

3y - 6 = -2x -2

3y = -2x -2 + 6

3y = -2x + 4

y = -2/3x + 4/3

Step-by-step explanation:

The current ratio is 3/4 pound of dried apples per 1/2 pound of dried pears. Since the new amount of dried pears is 1 pound or double the initial amount, the new amount of dried apples will be double the initial amount:

[tex]\frac{3}{4}\cdot 2=\frac{6}{4}=\frac{3}{2}=1\frac{1}{2}\:\mathrm{pounds}[/tex].

Answer:

m ≥ 0

Step-by-step explanation:

Since the cost is represented by c = 0.12m, the domain should be a positive number, this is because number of minutes can't be written in negative. Therefore, the most reasonable number for the domain would be the set of positive whole numbers which means, m≥0.

Answer:

315

Step-by-step explanation:

So with the ratio, you can tell that 11/18 of the people at the festival are kids, and 7/18 are adults.

Since you want to find the number of adults, just multiply.

7/18 x 810

You can cross multiply to get rid of 18 and 810 will simplify into 45. So then you are left with multiplying

7 x 45

=315

So, 315 is your answer

Answer: 315 Adults.

Step-by-step explanation:

Let the number of adults is x.

Then the number of kids is (810-x).

The ratio of kids to adults is

810 - x/x = 11/7

It is your basic equation, which you get from the condition.

To solve it, cross multiply; then simplify

7*(810-x) = 11x

7*810 - 7x = 11x

7*810 = 11x + 7x

7*810 = 18x

x = 7 x 810/18 = 315.
