Step-by-step explanation:

When you're drawing an inequality on a number line there are a few things to focus on:

- Whether your variable is greater than or less than the number

- Whether it can be equal to the number or not

If it can be equal to the number your first dot will be filled in, if not it will be hollow

When it's less than it means you're moving to the left on your number line, if it's greater than you move right

Answer:

answer is C. Rectangle

Step-by-step explanation:

The shape of the resulting two-dimensional cross section is a rectangle.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

A right triangular prism has a base that is a right triangle, and the prism has three perpendicular rectangular faces that join the two congruent triangles.

When this prism is sliced perpendicular to its base, the resulting two-dimensional cross-section will always be a rectangle.

This is because the cut will be perpendicular to the rectangular faces of the prism and the base triangle, resulting in a rectangle.

The length of the rectangle will be equal to the base of the triangle, and the width of the rectangle will be equal to the height of the prism.

Hence,  shape of the resulting two-dimensional cross section is a rectangle.

Answer: C

Step-by-step explanation:

The slope-intercept form of a line is given by

y = mx + b

m - slope

b - y-intercept

Segment AB lies on the line 6x + 3y = 12

6x + 3y = 12

3y = -6x + 12

​​y = -6/3​x +  12/3​  

y = -2x + 4

Comparing with the slope-intercept form,

Slope = - 2

y-intercept = 4

Segment CD lies on the line 4x + 2y = 8

4x + 2y = 8

2y = -4x + 8

y = -4/2​x +  8/2

y = - 2x + 4

Comparing with the slope-intercept form,

Slope = - 2

y-intercept = 4

Both the line segments have the same slope and the same y-intercept, so the two line segments will lie exactly on top of one another.

Therefore, the correct option is (c)

Last month the amount of rain that fell each day varied about the same as the month before is the right statement about the rainfall, Option c is correct.

The average distance between each data point and the mean is the mean absolute deviation of a dataset. It offers us an indication of how variable a dataset is.

The  given data in the problem is;

Two months ago,

The mean daily rainfall in a local city was 9. 4 cm.

The mean absolute deviation was 3. 5 cm

Last month

The mean daily rainfall in that city was 11. 5 cm

The mean absolute deviation was 1. 6 cm.

We can see that there was less variation last month than the month before since the mean absolute deviation is a measure of variance.

Hence Last month the amount of rain that fell each day varied about the same as the month before is the right statement about the rainfall, Option c is correct.

Answer:

See below.

Step-by-step explanation:

1.

y = 100 + 65x

y = 40 + 80x

100 + 65x = 40 + 80x

-15x = -60

x = 4

y = 100 + 65x = 100 + 260 = 360

(4, 360)

2.

The lines intersect at the point (4, 360).

At the point of intersection, where x = 4, it shows that by doing 4 hours of labor, both shops cost the same.

3.

Mike's:

y = 100 + 65x = 100 + 65(3) = 100 + 195 = 295

Amy's:

y = 40 + 80x = 40 + 80(3) = 40 + 240 = 280

For 3 hours of labor, Amy's shop is cheaper at $280. Mike's costs $295.

Answer:

1.  (4, 360)

2.  total cost at both repair shops is the same

3.  Amy's Auto Repair:  $280

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}y=100+65x\\y=40+80x\end{cases}[/tex]

Question 1

Solve by using the Substitution Method:

[tex]\implies 40+80x=100+65x[/tex]

[tex]\implies 40+80x-65x=100+65x-65x[/tex]

[tex]\implies 40+15x=100[/tex]

[tex]\implies 40+15x-40=100-40[/tex]

[tex]\implies 15x=60[/tex]

[tex]\implies 15x \div 15=60 \div 15[/tex]

[tex]\implies x=4[/tex]

Substitute the found value of x into one of the equations and solve for y:

[tex]\implies y=40+80(4)[/tex]

[tex]\implies y=40+320[/tex]

[tex]\implies y=360[/tex]

Therefore, the point of intersection is (4, 360)

Question 2

The two lines intersect at (4, 360).  This means that the total cost at both repair shops is the same when it takes 4 hours to repair the car.  The cost at this time is $360.

Question 2

To find the cost at both repair shops if it takes 3 hours to fix the car, substitute x = 3 into both equations and solve for y:

Mike's Repair shop:

[tex]\implies y=100+65(3)[/tex]

[tex]\implies y=100+195[/tex]

[tex]\implies y=295[/tex]

Amy's Auto Repair:

[tex]\implies y=40+80(3)[/tex]

[tex]\implies y=40+240[/tex]

[tex]\implies y=280[/tex]

Therefore, Amy's Auto Repair company is the cheapest at a cost of $280.

Calculate the area of the floor:

Area = 1.6 x 2.3 = 3.68 square meters

Using the given formula: Pressure = force/area

200 = force / 3.68

Solve for force by multiplying both sides by 3.68

Force = 200 x 3.68

Force = 736 N/m^2

Correct to the nearest 5N/m^2 = 735 N/m^2

First of all we need to calculate the area of the floor and then we will find the pressure using the formula for pressure...
