Answer:

The linear equation showing the total cost of tiling Dani's bathroom floor is: y = 3x + 50

The equation is in the form of "y = mx + b", where y represents the total cost, x represents the number of square feet, m represents the cost per square foot ($3), and b represents the fixed cost ($50). The linear equation is determined by using the information provided in the problem, which is the cost per square foot and the fixed cost.

Step-by-step explanation:

Yellow block closest side and farthest side: 2x1=2 2x2=4

Yellow block right and left side: 1x1=1 1x2=2

Yellow block bottom: 2x1=2

Yellow block top: 2x1=2

Purple block closest side and farthest side: 5x2=10 10x2=20

Purple block right and left side: 2x3=6 6x2=12

Purple block bottom: 5x3=15

Purple block top: 5x3=15 15-2=13

2+2+2+1+1+13+10+10+6+6+15= 68

The overlap effects the calculation of the surface area because the bottom of the yellow block and a part of the purple block overlaps making it so that you would count it two times instead of the area that is visible.

I like to think of it as spray painting the blocks and seeing where the paint sprays.

Answer: 3rd one

the 4th one doesn’t have anything to multiply it with

Answer: PART A:

Recall that the equation of a line in standard form is of the form:

ax + by = c

where a, b, and c are constants.

The equation of a line passing through two points:

and

is given by:

Given that Amir rented a scooter at $43 for 3 hours. If he rents the same scooter for 8 hours, he has to pay a total rent of $113.

This,

and

Thus, the equation of the line is given by:

Therefore, the equation of the line in standard form is

PART B:

To write the equation with a function notation, we first express y in terms of x and then change y notation to f(x) notation.

Recall from part 1:

Therefore, the equation obtained in Part A written using function notation is given by:

PART C:

To graph the equation obtained above, we draw the x- and y- axis with the x-axis labelled 'number of hours' and the y-axis labelled 'total rent'.

Next, we choose appropriate scales for x- and y- axis. Depending on the size of your graph book, you can choose an interval of 1 unit for the x-axis and an interval of 10 units for the y-axis.

From part A, we know that the line of the equation passes though points (3, 43) and (8, 113), mark these points and draw a straight line passing theough these points.

Answer:

y = 3/4x -1/4

Step-by-step explanation:

First, find the slope using the points (3, 2) and (-1, -1):

Slope = m = y2 -y1 / x2 -x1 = -1 -2 / -1 -3 = -3/-4 = 3/4

Find the y-intercept, b, by substituting x = -1, y = -1 and m = ¾ in y = mx + b.

-1 = ¾(-1) + b

-1 = -¾ + b

Add ¾ to both sides

-1 + ¾ = b

(-4 + 3)/4 = b

-¼ = b

Substitute m = ¾ and b = -¼ in y = mx + b.

The equation would be:

✅ Y = 3/4x - 1/4

Step-by-step explanation:

Answer: $81.32

Step-by-step explanation:

Answer: 1/9

Step-by-step explanation: We can start the problem by using the concept of unit rate.

We know that the gardener spread 2/3 of a bag of mulch over his 6 vegetable beds. To find the amount of mulch per bed, we can divide the total amount of mulch by the number of beds.

So, the unit rate of mulch per bed is (2/3) / 6 = 1/9 of a bag of mulch.

So, the gardener put 1/9 of a bag of mulch on each vegetable bed.

Answer: 1/9

Step-by-step explanation:

If it was one bag, it would have been 1÷6 and the answer would have been 1/6 for each vegetable bed.

So if we do the same with 2/3, this is (2/3)/6. Let’s try this:

=[tex]\frac{2}{3}[/tex]÷[tex]\frac{6}{1}[/tex]
=[tex]\frac{2}{3}[/tex]×[tex]\frac{1}{6}[/tex]

=[tex]\frac{2}{19}[/tex]

=[tex]\frac{1}{9}[/tex]

Therefore, the gardener put 1/9th of the bag of mulch on each vegetable bed.

Answer:

make two points or three points on the graph to make sure you're correct

First point: x=2  y=2x4=8  (2,8)

Second point x=0 y=0  (0,0)

Third point: x= -2 y= -2x4= -8  (-2,-8)

Answer: A basic definition of surface area would be defined  as the amount of space that is covering the outside of a 3D shape. A example of real world surface are would be to find out how much frosting you would need to put on the surface of a cake

Answer: 4 gallons

Step-by-step explanation:

I am pretty sure it is 4 gallons because if you multiply 3.8(2)=7.6 and then 3.8(3)=11.4 and finally 3.8(4)=15.2

So that is why I think that the smallest gallon water cooler they will need too by is a 4-gallon cooler.

Answer: 27 students have black shoes.

There are 3 people who have black shoes out of 7 (3+4=7)

You have: 3/7

Find the variable: 3/7: x/63

63 divided by 7 = 9

3x9=27 students who have black shoes

Answer: A = 490.63 mm^2

Step-by-step explanation:  Hello! To find the area of a circle, you have to find the radius of the circle from the circumference given.  The formula is Circumference/2(3.14) = Radius.  To find the circumference, multiply 25 x pi, or 25 x 3.14.  25 x 3.14 is 78.5.  Put 78.5 in the equation for the circumference.  78.5/2(3.14) = Radius

Simplify:
78.5/6.28 = 12.5

The radius is approximately 12.5.

The formula for the area of a circle is 3.14 x r^2  = A

Put 12.5 in for r or radius

3.14 x 12.5^2 = A, 12.5^2 = 156.25

3.14 x 156.25 = A

3.14 x 156.25 = 490.625

Rounded to the nearest hundredth is A = 490.63

Answer: hope this helps ♡

The approximate area of the circle is 49.736 mm²

Step-by-step explanation:

Area of circle = π × r²

To find the radius:

25 ÷ 3.14 = 7.96178343949 (← diameter  d = 2r)

7.96178343949 ÷ 2 = 3.98089171974 (radius)

π × r² =

3.14 × 3.98089171974² =

3.14 × 15.8474988843 =

49.7611464967 ≈ 49.736

Answer:

The table will fit

Step-by-step explanation:

Table: 2 3/8 = 19/8

Door: 2 3/4 = 11/4

(Mixed fraction to Improper fraction)

Door: 2 3/4 = 11/4 = 11/4*2 = 22/8

19/8 (Table) > 22/8 (Door)

(Hopefully thats the answer 'cause the question isn't very readable)
