Answer:

The first one is 8/12.

Step-by-step explanation:Add numerator and keep denominator same.

Answer:

5/12 + 3/12

Step-by-step explanation:

[tex]\frac{5}{12} + \frac{3}{12} = \frac{8}{12}[/tex]

This is because when adding fractions with the same denominator, you just add the numerators.

The other answer choices do not equal 8/12...

[tex]\frac{2}{4} + \frac{3}{4} + \frac{3}{4} = \frac{8}{4} = 2[/tex]

[tex]\frac{2}{3} + \frac{3}{4} + \frac{3}{5} = \frac{40}{60} + \frac{45}{60} + \frac{36}{60} = \frac{121}{60} = 2 \frac{1}{60}[/tex]

[tex]\frac{4}{6} + \frac{4}{6} = \frac{8}{6} = \frac{4}{3} = 1 \frac{1}{3}[/tex]

Answer:

The painter paint the room by himself in 12h.

Step-by-step explanation:

If we consider that the room is the distance that the painter and his friend need to paint, then each person will have a painting speed and if we sum them they will finish the room in 8 hours. If we call the speed of the painter "x" and the his time "tx", while his friend will be "y" and his time will be "ty". We can apply each case to the average speed formula:

Both working together:

speed = distance / time

x + y = room / 8

The friend alone:

y = room / ty

The painter alone:

x = room / tx

Therefore:

(room/tx) + (room/ty) = room/8

1/tx + 1/ty = 1/8

(tx + ty)/tx*ty = 1/8

8*tx + 8*ty  = tx*ty

Since tx = ty - 12, we have:

8*ty - 96 + 8*ty = ty² - 12*ty

ty² - 12*ty - 16*ty + 96 = 0

ty² - 28*ty + 96 = 0

ty = 4 or ty = 24

Since tx = ty - 12, ty can only be 24, because if it was 4, then the painter time would be negative and that is impossible. So we have:

ty = 24

tx = 24 - 12 = 12

The painter paint the room by himself in 12h.

The painter to paint the room by himself in 12 hours

Let

Friend

x = room / time taken

Painter

y = room / time taken

painter and friend

x + y = room / 8

(room/friend time ) + (room/painter time) = room/8

1/friend time + 1/painter time = 1/8

(friend time + painter time)/friend time × painter time = 1/8

8 × friend time + 8 × painter time =friend time × painter time

Since friend time = painter time - 12, we have:

8 × painter time - 96 + 8 × painter time = painter time² - 12 × painter time

Painter time² - 12 × painter time - 16 × painter time + 96 = 0

painter time² - 28 × painter time + 96 = 0

Pt = 4 or = 24

Since friend time = painter time - 12,

Painter can is 24, because if it is 4, then the painter time would be negative and that is impossible.

So,

Painter = 24

Friend time = 24 - 12 = 12

Therefore, the painter paint the room by himself in 12 hours

Step-by-step explanation:

1042 square inches is the total surface area of composite solids.

It is clear from the image that the resulting composite solid is a cuboid.

whose sides are as follows

Across the length, there are 3 blocks along the side of 7 inches each.

[tex]Length = 7 \times 3 = 21\ inch[/tex]

Width = 5 inch

Across the height, there are 4 blocks along the side of 4 inches each.

[tex]Height = 4 \times 4 = 16\ inch[/tex]

[tex]\text{Total Surface Area = } 2 (l\times w+ w \times h+ h \times l)[/tex]

We know that the total surface area of a cuboid is,

[tex]\text{Total Surface Area = } 2 (l\times w+ w \times h+ h \times l)\Rightarrow 2 (21 \times 5 + 16 \times 21 + 16 \times 5 )\\\Rightarrow 2 (105 + 336+80)\\\Rightarrow 2 \times 521\\\Rightarrow 1024[/tex]

Therefore, the total surface area = 1024 square inches.

Answer:

The cost of renting will be the same for 200 miles.

Step-by-step explanation:

Let n the number of miles and C be the cost. We can represent the cost equations for each companies:

A: C = 12 + 0.09n

B: C = 8 + 0.11n

They want to know when the cost will be the same, so we can set the above 2 equations equal to each other and solve for n:

12 + 0.09n = 8 + 0.11n

0.02n = 4

n = 200

Answer:

p = - 11, p = 3

Step-by-step explanation:

Given

p² + 8p - 33 = 0 ( add 33 to both sides )

p² + 8p = 33

To complete the square

add ( half the coefficient of the p- term )² to both sides

p² + 2(4)p + 16 = 33 + 16

(p + 4)² = 49 ( take the square root of both sides )

p + 4 = ± [tex]\sqrt{49}[/tex] = ± 7 ( subtract 4 from both sides )

p = - 4 ± 7

Thus

p = - 4 - 7 = - 11

p = - 4 + 7 = 3

Answer:

C. 6 ways

Step-by-step explanation:

When two fair dice are rolled, the sample space of the outcome  is given below:

[tex](1,1) (1,2) (1,3) (1,4) (1,5) (1,6)\\(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)\\(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)\\(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)\\(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)\\(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)[/tex]

Where in the pair (x,y), x represents the red die and y represents the white die.

The outcome in which the sum of the two dice is less than 5 are:

[tex](1,1) (1,2) (1,3) \\(2,1) (2,2) \\(3,1)[/tex]

Therefore, this result can be obtained in 6 ways.

The correct option is C.

Considering all the possible outcomes, it is found that the number of times a sum of the two dice less than 5 can be obtained is:

C. 6 ways

(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)

(2,1), (2,2), (2,3), (2,4), (2,5), (2,6)

(6,1), (6,2), (6,3), (6,4), (6,5), (6,6)

Of those, the ones with a sum of less than 5 are given by:

(1,1), (1,2), (1,3), (2,1), (2,2), (3,1)

6 ways, hence option C is correct.

Answer:

11in.2

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the quadratic equation  6x² + 24x + 7 = 0, the following steps must be followed when finding the roots using the completing the square method.

Step 1: Subtract 7 from both sides

6x² + 24x + 7 - 7= 0 -7

6x² + 24x = -7

Step 2: divide through by the coefficient of x²

6x²/6 + 24x/6 = -7/6

x² + 4x = -7/6

Step 3: Add half of the coefficient of x (i.e 4/2 = 2) to both sides of the equation to complete the square of the equation x² + 4x.

x² + 4x + 2= -7/6 + 2

(x+2)² = -7/6 + 2

(x+2)²  = 5/6

Step 4: taking the square root of both sides

√(x+2)²  = √5/6

x+2 = ±√5/6

x = -2±√5/6

x = -2+√5/6 and -2-√5/6

Based on the conclusion above, it can be seen that Yvonne made the first error in step 2. Yvonne suppose to divide through by the coefficient of x² (i.e 6)
