Answer: 1 3/5

Step-by-step explanation:

From the question, we are informed that five friends are sharing 8 cups of lemonade and that they share the lemonade equally.

The number of cups that each friend gets will be calculated by dividing the number of cups of lemonade by the number of friends. This will be:

= 8 / 5

= 1 3/5

Answer:

£22 : £44 : £66 : £110

Step-by-step explanation:

sum the parts of the ratio, 1 + 2 + 3 + 5 = 11 parts

Divide the amount by 11 to find the value of 1 part of the ratio

£242 ÷ 11 = £22 ← value of 1 part of the ratio, then

2 parts = 2 × £22 = £44

3 parts = 3 × £22 = £66

5 parts = 5 × £22 = £110

Then £242 in the ratio 1 : 2 : 3 : 5 is £22 : £44 : £66 : £110

Answer:

9

Step-by-step explanation:

you multiply 1.5 x 6

Step-by-step explanation:

First, let us assume x = share of the first person who owns 6 tacos and y = the share of the other person whom x shared his tacos with.

[tex]6 = x + y \\ but \: y = 1.6 + x \\ 6 = x + (1.6 + x) \\ 6 - 1.6 = x + x \\ \frac{4.4}{2} = \frac{2x}{2} \\ 2.2 = x \\ \\ y = 1.6 + x \\ = 1.6 + 2.2 \\ = 3.8[/tex]

The correct statement about the graph will be;

''The graph of the function is positive on (-∞, –7).''

Option C is true.

What is Function?

A relation between a set of inputs having one output each is called a function.

Given that;

A polynomial function has a root of –7 with multiplicity 2, a root of –1 with multiplicity 1, root of 2 with multiplicity 4, and a root of 4 with multiplicity 1.  

And, The function has a positive leading coefficient and is of even degree.

Now,

A polynomial function has a root of –7 with multiplicity 2.

Then, we get;

(x + 7)²

And, a root of –1 with multiplicity 1.

Then, we get;

(x + 1)¹ = (x - 1)

And, a root of 2 with multiplicity 4.

Then, we get;

(x - 2)⁴

And, a root of 4 with multiplicity 1.

Then, we get;

(x - 4)¹ = (x - 4)

So, The polynomial is;

P(x) = a (x + 7)² (x + 1) (x - 2)⁴ (x - 4)

After rearranged we get;

P (x) = a (x + 7)²(x - 2)⁴(x + 1) (x - 4)

Now, We check all options as;

For option A; The graph of the function is positive on (2, 4).

Substitute (x, y) = (2, 4) in the polynomial;

P(3) = a  (3 + 7)²(3 - 2)⁴(3 + 1) (3 - 4)

      = a × 100 × 1 × 4 × -1

      = -400a

Thus, The graph of the function is negative on (2, 4).

So, Option A is false.

For option B; The graph of the function is negative on (4,infinity).

Substitute x = 6;

P(6) = a  (6 + 7)²(6 - 2)⁴(6 + 1) (6 - 4)

      = a × 169 × 16 × 7 × 2

      = 37,856a

Thus, The graph of the function is positive on (4,infinity).

So, Option B is false.

For option C; The graph of the function is positive on (-infinity, –7).

Substitute x = -8;

P(-8) = a  (-8 + 7)²(-8 - 2)⁴(- 8 + 1) (-8 - 4)

      = a × 1 × 10,000 × -7 × -12

      = 840,000a

Thus, The graph of the function is positive on (-infinity, –7).

Option C is true.

Therefore, The correct statement about the graph will be;

''The graph of the function is positive on (-∞, –7).''

Option C is true.

b. 11-4= 7 used books. So the ratio of used books to all books is 11/7

Answer:

16 m  × 11 m

Step-by-step explanation:

The dimension of the gym is 20 m x 15 m. An outbound of 2m width is to be cut out from the gym to form the basketball court.

The original length of gym = 20 m and original width of gym = 15 m

2 m would be cut at both sides of the gym length for the outbound. Also 2 m would be cut at both sides of the gym width for the outbound. Therefore:

Length of basketball court = 20 m - (2 * 2m) = 20 m - 4 m = 16 m

Width of basketball court = 15 m - (2 * 2m) = 15 m - 4 m = 11 m

Therefore the dimensions of the basketball court is:

16 m × 11 m

Graph below

Step-by-step explanation:

Graph of a Function

We are given the function

y = f(x) = -4/3x + 8

Since this is the equation of a line, we only need two points to draw the graph, but we'll calculate some points more.

Select values for x={-3, 0, 3, 6, 9}

For x=-3:

y = -4/3(-3) + 8 = 4 + 8 = 12

Point (-3,12)

For x=0:

y = -4/3(0) + 8 = 0 + 8 = 8

Point (0,8)

For x=3:

y = -4/3(3) + 8 = -4 + 8 = 4

Point (3,4)

For x=6:

y = -4/3(6) + 8 = -8 + 8 = 0

Point (6,0)

For x=9:

y = -4/3(9) + 8 = -12 + 8 = -4

Point (9,-4)

Now plot the points in a rectangular grid and join them. The graph is shown below.

Answer:

the gross monthly income last month is $3,318.92

Step-by-step explanation:

The computation of the gross monthly income last month is shown below:

= Total sales × commission percentage

= $82,968 × 4%

= $3,318.92

hence, the gross monthly income last month is $3,318.92

We simply multiplied the total sales with the commission percentage
