A positive and a negative become a negative. First you convery the mixed fraction into an improper fraction, then you find the common denominator of all fractions, next step according to PEMDAS, you can add and subtract in any order you would like too.

1. -7 2/3 - 5 1/2 + 8 3/4

2. -23/3 - 11/2 + 35/4

3. -92/12 - 66/12 + 105/12 The common denominator is 12.

4. -92/12 - 66/12 = -158/12 A negative and a negative is addition but just add the negative sign.

5. -158/12 + 105/12 = -53/12 =

Find the missing side.

Answers

Answer:

x = 10 units

Step-by-step explanation:

The formula for the area of a triangle of base x and height h is A = (1/2)(x)(h).

Here A = (1/2)(x)(8) = 40, so 8x = 80 and x = 10 units

If we look at this triangle we can see the straight line (the height). We want to use the height to figure out the side? Well divide 40 with the height (8). And now you get 5(cause 5*8 is 40. duh)

Step-by-step explanation:

You half $5.04 (the cost of two lbs of cranberries) and get $2.52 then multiply by x (the lbs.) equals y the cost of all the lbs. of cranberries.

Therefore getting the equation of y= 2.52x

Answer: y=2.52x

Step-by-step explanation:

if you take any of the statements you can calculate it.

Let "x" be pounds, and "y" the total cost of x pounds.

2x=5.04

Divide by 2

x=5.04/2

x=2.52

Given: m∠ABC = 50°,
AC = 30
Find: OA

Answers

Answer:

OA = 19.58

Step-by-step explanation:

If we draw the segments OA and OC, we will have an isosceles triangle OAC.

With the property of inscribed angles and central angles that are related to the same arc of the circunference, we have:

mAOC = 2 * mABC

mAOC = 2 * 50 = 100°

As the triangle OAC is isosceles, we have that mOAC = mACO.

Knowing that the sum of internal angles of a triangle is 180°, we have:

mACO + mOAC + 100 = 180

2 * mACO  = 80

mACO = 40°

Now, using the law of sines, we have:

OA / sin(ACO) = AC / sin(AOC)

OA / 0.6428 = 30 / 0.9848

OA = 30.463 * 0.6428 = 19.58

You have a jar of marbles with 7 red, 12 blue, 6 yellow, and 9 white. What is the probability of selecting a marble that is not red, replacing it and then one that
is white?​

Answers

Answer:

The probability of selecting a marble that is not red, replacing it and then one that  is white is 0.2102

Step-by-step explanation:

Number of red marbles = 7

Number of blue marbles = 12

Number of yellow marbles = 6

Number of white marbles = 9

Total marbles = 7+12+6+9=34

Probability of selecting red marble =[tex]\frac{7}{34}[/tex]

Probability of selecting no red marble = [tex]1-\frac{7}{34}=\frac{27}{34}[/tex]

Now replacing it one marble is drawn again

So, Probability of getting white marble [tex]=\frac{9}{34}[/tex]

So,the probability of selecting a marble that is not red, replacing it and then one that  is white =[tex]\frac{27}{34} \times \frac{9}{34}=0.2102[/tex]

Hence the probability of selecting a marble that is not red, replacing it and then one that  is white is 0.2102

Sal is tiling his entryway. The floor plan is drawn on a unit grid. Each unit length represents 1 foot. Tile costs $1.85 per square foot. How much will Sal pay to tile his entryway? Round your answer to the nearest cent.

Answers

Answer:

$80.48

Attached is the image of the entry way

Step-by-step explanation:

Given that each unit length represents 1 foot.

To find the area of the shape shown in the attached image, we need to divide the shape into two parts at about 4 ft from the bottom.

The top shape is a trapezoid of base length 4 ft, top length 7 ftand height 5 ft, while the bottom shape is a parallelogram with one side equal to 4 ft and height 4 ft

Area of a Trapezium = 1/2 × (a+b)h

a = 4ft, b= 7ft, h = 5ft

Substituting the values;

Area of trapezoid = 1/2 × (7 + 4)x 5

Area of trapezoid = 27.5 ft^2

Area of a parallelogram = length × height

Length = 4 ft, height = 4 ft

Substituting the values;

Area of parallelogram = 4 x 4

Area of parallelogram = 16 ft^2

Total area = area of trapezium + parallelogram

Total area = 27.5 + 16 = 43.5 ft^2

Cost per square foot = $ 1.85

Total cost = cost per square foot × area

Total cost = $1.85 per square foot × 43.5ft^2

Total Cost = $80.48

Answer:

Sal will pay $ 80.48  to tile his entryway.

Step-by-step explanation:

Separate the entryway into simpler shapes: a trapezoid and a parallelogram.

Find the area of the simpler figures. Count units to find the dimensions.

Trapezoid

A =   1/ 2

h(b₁ + b₂)

A =   1/ 2

(5)(4 + 7)

A =   1/ 2

(5)(11)

A = 27.5

The area of the trapezoid is 27.5 ft  

2 .

Parallelogram

A = bh

A = 4 · 4

A = 16

The area of the parallelogram is 16 ft  

2 .

Find the area of the entryway.

A = 27.5 + 16

A = 43.5

The area of the entryway is 43.5 ft  

2 .

Calculate how much Sal will pay to tile his entryway.

Area · Cost per foot =  Total Cost

43.5 · $1.95 =  $84.83

Sal will pay $84.83 to tile his entryway.

Use conversions to solve the problem. Yesenia buys juice to make punch for all her friends. She buys 1 quart of juice and one eighth gallon of juice. How many cups of juice does she ​buy?

Answers

Answer:

The cups of juice that Yesenia buys are:

6 cups.

Step-by-step explanation:

To solve this, you need to know the conversión below:

1 gallon = 16 cups.

Now the paragraph mentions that Yesenia buys 1 quart of juice (that refers to a quart of gallon), then, having the conversion above we can operate with a rule of three:

1 gallon = 16 cups1/4 gallon = X

Solving this we have:

(1/4 * 16)/1 = 4 cups

In the first purchase, Yesenia actually buys 4 cups (that is the same to 1 quart of gallon), next she buys one eighth, then we operate again with the first conversion but using this new quantity:

1 gallon = 16 cups1/8 gallon = X

Solving this we have:

(1/8 * 16)/1 = 2 cups

By last, we add every purchase:

Number cups of juice purchased by Yesenia = 4 cups + 2 cups = 6 cups.

2.2

Answers

Answer:

A. 4.5

Step-by-step explanation:

Given:

20, 12, 27, 23, 18, 20, 30, 26

Mean = 22

Required:

Calculate the Mean Absolute Deviation (M.A.D)

Since, we have the mean; we start calculating M.A.D by subtracting the mean from each data

20 - 22 = -2

12 - 22 = -10

27 - 22 = 5

23 - 22 = 1

18 - 22 = -4

20 -22 = -2

30 - 22 = 8

26 - 22 = 4

The we find absolute value of the result above

|-2| = 2

|-10| = 10

|5| = 5

|1| = 1

|-4| = 4

|-2| = 2

|8| = 8

|4| = 4

Lastly, we calculate the mean of the above to give M.A.D

[tex]M.A.D = \frac{2 + 10 + 5 + 1 + 4 + 2 + 8 + 4}{8}[/tex]

[tex]M.A.D = \frac{36}{8}[/tex]

[tex]M.A.D = 4.5[/tex]

Option A is correct.

The value of the mean absolute deviation is 4.5 hours if the mean of the data set is 22 hours, option first is correct.

What is the mean absolute deviation?

It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance is known as the MAD.

We have data:

20, 12, 27, 23, 18, 20, 30, 26

Mean of the data X = 22 hours

∑(x - X) = 36

MAD = 36/8 = 4.5 hours

Thus, the value of the mean absolute deviation is 4.5 hours if the mean of the data set is 22 hours.
