Answer:

The expressions for the payment made to Mary are,

(Monday) 90 = 15m + b

(Tuesday) 62 = 8m + b

where m and b are the fee per student and the base fee, respectively. Solving for m and b, the values are 4 and 30.

The equation that represents Mary's earning is

y = 4x + 30

For 20 students,

y = 4(20) + 30 = 110

For Lisa's earnings,

y = 8x + 15

Substituting 20,

y =8(20) + 15 = 175

Thus, Lisa would earn more than Mary by $65.

(Btw this is not my work, I got it from someone else on brainly and wanted to help lol)

Baseballs and softballs com in different sizes for different leagues. If the diameter of a baseball is 3 inches and a softball i
Vanyuwa [196]

Answer:

Step-by-step explanation:

Alright, lets get started.

Diameter of baseball is given as 3 inches.

Hence the radius of baseball will be : \frac{3}{2}=1.5

Hence the volume of baseball is : \frac{4}{3}\pir^3

Hence the volume of baseball is : \frac{4}{3}\pi1.5^3

Hence the volume of baseball is : 14.13 inches cube

Now, diameter of softball is given as 3.8 inches.

Hence the radius of softball will be : \frac{3.8}{2}=1.9

Hence the volume of baseball is : \frac{4}{3}\pir^3

Hence the volume of baseball is : \frac{4}{3}\pi1.9^3

Hence the volume of baseball is : 28.72 inches cube

Hence the difference of volumes will be: 28.72-14.13

Hence the difference of volumes will be 14.59 or 14.6 inches cube

So the answer is 14.6 inches cube.    :    Answer

Hope it will help :)

Billy graphed the system of linear equations to find an approximate solution.
jeka57 [31]

The points that are possible approximations for this system are; (2.2, -1.4) and (2.2, -1.35)

<h3>How to find the solution of a linear graph?</h3>

We are given the equations of the linear graphs as;

y = ⁷/₄x + ⁵/₂

y = ³/₄x - 3

Notice that the lines intersect each other and by definition, if the lines of the system of equations intersect, then the system has one solution. This means that the point of intersection of the lines is the solution of the system. It can be written as:

(x, y)

x is the x-coordinate .

y is the y-coordinate.

In this case, we can identify that:

- the x-coordinate of the point of intersection is between; x = 2 and x = 3

- The y-coordinate of the point of intersection is between y = -1 and y = -2

Based on the above, we can conclude that the points that are possible approximations for this system are; (2.2, -1.4) and (2.2, -1.35)
