Answer:

Ria earns 14.88 dollars each week

Step-by-step explanation:

Amount earned by peter every week = $12.40

If Ria earns 1.2 times as money per week as Peter, then;

Amount Ria earns = 1.2 * 12.40

Amount Ria earns = 14.88

Hence Ria earns 14.88 dollars each week

Answer:

$26.25

Step-by-step explanation:

We are told that Marco needs to buy some cat food. At the nearest store, 3 bags of cat food cost $15.75.  

First of all we will find cost of 1 bag of cat food by dividing 15.75 by 3.

Now we will find the amount that Marco has spend for 5 bags of cat food by multiplying 5.25 by 5.  

Therefore, Marco has spend $26.25 for purchasing 5 bags of cat food.    

Answer:

5.25 per bag

Step-by-step explanation:

Just divide the amount of money by the number of bags needed.

15.75 divided by 3 = 5.25

Answer:

9.19 ft

Step-by-step explanation:

Since it's a square, we know that all the sides are equal to 26/4 which equals 6.5. Then, we use the Pythagorean theorem to calculate the diagonal (since the diagonal is splitting the square into two right triangles). So we to a^2+b^2=c^2. So 42.25+42.25=84.5. The square root of 84.5 rounded to the nearest tenth is 9.19

Answer:

The perimeter of the pentagon is;

29 units

Step-by-step explanation:

Let A, B, C, D, and E represent the vertices of the pentagon

The "x" and "y" coordinates of the vertices of the pentagon are given as follows;

A(-6, 2), B(-2, -2), C(5, -2), D(5, 2), E(-2, 5)

The length of the sides between each pair of coordinates can be found using the following formula;

[tex]l = \sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}[/tex]

Therefore, we have;

Length of segment AB = √((-2 - (2))² + (-2 - (-6))²) = 4·√2

Length of segment BC = √((-2 - (-2))² + (5 - (-2))²) = 7

Length of segment CD = √((5 - 5)² + (2 - (-2))²) = 4

Length of segment DE = √((5 - 2)² + (-2 - 5)²) = √58

Length of segment EA = √((5 - (2))² + (-2 - (-6))²) = 5

The length of the perimeter of the pentagon = 5+√58 + 4 + 7 + 4·√2 ≈ 29.2726273554 ≈ 29

The length of the perimeter of the pentagon ≈ 29.

Answer:

c(0) = 24*0 = 0  

c(8) = 24*8 = 192  

Your range is [0,192]

Step-by-step explanation:

Answer:

You have 8 cups of flour it takes 1 cup of flour to make 24 cookies the function c(f)=24f

c represents the number of cookies

f represents the cups of flour

You have 8 cups of  flour, we can use only 0 to 8 cups of flour.

so domain f is 0 to 8 cups [0,8]

Now we find the range

1 cup of flour to make 24 cookies

So 8 cups of flour = 24* 8 = 192 cookies

using 8 cups you can make 192 cookies

So number of cookies is from 0 to 192

Range is [0,192

Hello there! ;)

1 is neither prime nor composite.

Prime numbers have 2 factors.

Composite numbers have 3 or more factors.

However, 1 has 1 factor.

Therefore, it's neither prime nor composite.

Answer:

Elimination

Step-by-step explanation:

The following system of equations can be easily solved by elimination as we can simply eliminate x-term.

Substitution will take a lot of time because you need to move to make either x-term or y-term as the subject then substitute in.

Graphing Method — You need to find the intercepts of both equations. You also have to convert into slope-intercept form which takes a lot of time.

Answer:

The answer is 35

Step-by-step explanation:

It wants to know how many basketball and baseball players there are. If there are 20 basketball players and the ratio is 4:3 then you need to divide the number of basketball players by 4 then multiply by 3. Add 20 to that number and the answer is C

Answer:

35

Step-by-step explanation:

I came up with 35 because 20/4= 5, so we are multiplying players by 5. Similarly, 3x5=15 for baseball players. 20 basketball players plus 15 baseball players is 35. I hope this helps!

Answer:

10

Step-by-step explanation:

To obtain the length of the segment :

a² + b² = c²

a = 8 ; b = 6

8² + 6² = c²

64 + 36 = c²

100 = c²

Square root of both sides :

Sqrt(100) = sqrt(c²)

10 = c

Mistake in the solution is that 6² = 36 and not 12

Answer:

E

Step-by-step explanation:

The statements that are not true are:

The graph has a y-intercept at (0,5) is not true.

The graph has a relative maximum point (-3,4) is not true,

The graph has zeros at x = -5 and x = -1 is not true.

Options, A, B, and E are the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

- The y-intercept can be found by setting x=0, which gives f(0)=-5.

So the y-intercept is (0,-5).

- To find the relative maximum,

We need to find the vertex of the parabola.

The x-coordinate of the vertex is given by -b/2a, where a=-1 and b=-6.

So, x=3 is the x-coordinate of the vertex.

To find the y-coordinate, we plug in x=3 into the function:

f(3) = -(3²) - 6 (3) - 5 = -32.

So the vertex is (3,-32), which is a relative minimum, not a maximum.

- To find the x-intercepts,

We set y  =0 and solve for x.

-x² - 6x - 5 = 0.

Factoring or using the quadratic formula,

We get x = -5 and x = -1.

- The y-axis is a line of symmetry for any parabola of form f(x)=ax²,

f(-x) = a (-x)² = ax² = f(x).

- To find the zeros,

We set f(x) = 0 and solve for x.

-x² - 6x - 5 = 0.

Factoring or using the quadratic formula,

We get x = -5 and x = -1.

So the graph has zeros at x = -5 and x = -1, not x = -2 and x = 3.

- The graph represents the function f(x) = -x2 - 6x - 5.

The graph is true.

Thus,

The graph has a y-intercept at (0,5) is not true.

The graph has a relative maximum point (-3,4) is not true,

The graph has zeros at x = -5 and x = -1 is not true.
