Answer:

Probability of getting Dr. Pepper the fourth time = [tex]\frac{1}7[/tex]

Probability of getting a cherry coke the fifth time = [tex]\frac{1}{3}[/tex]

Combined probability = [tex]\frac{1}{21}[/tex]

Step-by-step explanation:

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

It is given that first time a Cherry coke is chosen and it is not replaced.

So, number of cherry coke left = 2

Dr. Pepper is chosen twice and is not replaced, so

Number of Dr. Pepper left = 3 - 2 = 1

Total number of soda left = 10 - 3 = 7

So, probability of getting Dr. Pepper the fourth time = [tex]\frac{1}7[/tex]

Now, total number of soda left = 7 - 1 = 6

Probability of getting a cherry coke the fifth time = [tex]\frac{2}{6} = \frac{1}{3}[/tex]

The combined probability = probability of getting Dr. Pepper the fourth time multiplied with Probability of getting a cherry coke the fifth time

[tex]\Rightarrow \dfrac{1}7 \times \dfrac{1}{3} = \dfrac{1}{21}[/tex]

Answer:

The actual distance between the two houses is:

3.2 km

Step-by-step explanation:

Proportions:

1cm       ⇔  100000 cm

3.2 cm  ⇔  W cm

W = 3.2*100000/1

W = 320000 cm

1 km = 100000 cm

320000cm = 320000/100000 = 3.2km

Corrected Question:

The length of a rectangle is (t – 8) units, and its width is (t + 11) units. Which expression can represent the area of the rectangle?

Answer:

t² + 3t - 88

Step-by-step explanation:

Given:

Rectangle of;

length = (t - 8) units

width = (t + 11) units

The area A of a rectangle is given by;

A  = length x width ----------------------------------(i)

Substitute the given length and width into equation (i) as follows;

A = (t - 8) x (t + 11)    [expand the brackets]

A = t² -8t + 11t - 88

A = t² + 3t - 88

Therefore, the area is

(t² + 3t - 88) square units

Answer:

32

Step-by-step explanation:

We are given the expression:

[tex]\frac{-8(13-37)}{6}[/tex]

and asked to evaluate the expression.

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

Solve inside the parentheses first. Subtract 37 from 13.

⇒ 13-37= -24

[tex]\frac{-8(-24 )}{6}[/tex]

Next, multiply -8 and -24.

⇒ -8*-24= 192

[tex]\frac{192}{6}[/tex]

Finally. divide 192 by 6.

⇒ 192/6 = 32

[tex]32[/tex]

When evaluated, the expression -8(13-37)/6 is equal to 32.

Answer:

169.2cm

Step-by-step explanation:

56.4cm + 56.4=  112.8+ 56.4=   169.2cm

The combined height of the 3 stacked boxes will be 169.2 cm so option (D) will be correct.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Summation = addition of two or more numbers or variable

For example = 2 + 8 + 9

Subtraction = Minus of any two or more numbers with each other called subtraction.

For example = 4 - 8

Division = divide any two numbers or variable called division.

For example 4/8

Multiplication = to multiply any two or more numbers or variables called multiplication.

For example 5 × 7.

Given that,

Height of one box = 56.4 cm

So,

Height of two boxes = Height of one box + Height of one box

It means

Height of three boxes = Height of one box + Height of one box + Height of one box

So,

Height of three boxes = 56.4 +  56.4 +  56.4

Height of three boxes = 169.2 cm

Hence "The combined height of the 3 stacked boxes will be 169.2 cm".

Answer: Her weekly allowance is 24 dollars

Step-by-step explanation:

If she is left with $12 spending half of her weekly allowance the we could set up the equation.

1/2 of x = 12  where x is her weekly allowance.

1/2x = 12  

x = 24

Answer: x=-6

Step-by-step explanation:

9(x+3)=4x-3

9x+27=4x-3 ⇔ distributive property (take off parentheses)

5x+27=-3 ⇔ subtraction property of equality (subtract 4x on both sides)

      5x=-30 ⇔ subtraction property of equality (subtract 27 on both sides)

        x=-6

Hope this helps!! :)

Please let me know if you have any question

Answer:

simplify both sides and get 9x+27=4x+−3 then subtract 4x and get  5x+27=−3 and subtract -27 and divide answer by 5 to get x=-6

Answer:

B and C

Step-by-step explanation:

We are given a rectangular prism that consists of 10 cubes. Each cube = 1 cm³. The volume of rectangular prism given = 10cm³.

Let's find out which of the options has same volume (10cm³) as that of the given rectangular prism.

Option A has 15 cubes = 15 cm³ in volume

Option B has 10 cubes = 10 cm³ in volume

Option C has 10 cubes also = 10 cm³ in volume

Option D has 12 cubes = 12 cm³

The rectangular prisms that have the same volume (10 cm³) with the given rectangular prism are option B and C.

3.)

•What do you know?

-It’s about 425 miles from San Jose to Los Angeles and 320 miles from San Jose to Santa Barbara.

•What do you want to find out?

-How many miles it is from Santa Barbara to Los Angeles.

•What kind of answer do you expect?

-If using variable, I expect that I will get the number of miles from one city to the other.

5.)

425 = 320 + X

6.)

425 = 320 + X

Subtract 320 from both sides.

7.)

X = 105

From Santa Barbra to Los Angeles it is 105 miles.

8.)

320 + 105 = 425

Answer:

Step-by-step explanation:

Given the equation y = 0.18x, to solve for x, we will make the variable x as the subject of the formula from the equation given.

From the equation y = 0.18x

Divide both sides by the coefficient of x i.e 0.18

y/0.18 = 0.18x/0.18

y/0.18 = x

Hence the function of the variable x = y/0.18

b) Given the amount of the bill as y and x is the tip in dollars.

Given  y = $4.95, we are to substitute the value of y = $4.95 into the resulting function in (a) to get x as shown;

Since x = y/0.18

x = $4.95/0.18

x = $27.5

Hence the bill is  $27.5

Answer:

x = -6

Step-by-step explanation:

[tex]-3x = 18\\\\\mathrm{Divide\:both\:sides\:by\:}-3\\\frac{-3x}{-3}=\frac{18}{-3}\\\\Simplify\\x=-6[/tex]

Answer:

8.7

Step-by-step explanation:

Since a square has equal side lengths, the formula for area is s^2, where s stands for side. Since we are given the area, s^2=75 square feet. Take the square root of both sides to get s is equivalent to the square root of 75 square feet. When this becomes a decimal, it is 8.66 feet. Since we are supposed to round to the nearest tenths, it rounds up to 8.7 feet per side length

9Answer: Y-1=-2(X+1) OR Y+9 = -2(X-4)

Step-by-step explanation:

Point slope form is Y-Y1=m(X-X1)

Slope (M) is (Y2-Y1)/(X2-X1)

SO M= (-9-1)/(4--1)

-10/5

M= -2

Answer:

y - 1 = -2 (x + 1)

Explanation:

point slope form: (y - y1) = m (x - x1)

m is the slope. To find m the formula is:

             (y2 - y1) / (x2 - x1)

The given ordered pairs are: (-1,1) and (4,-9)

y2 is the y in the second ordered pair (-9)

y1 is y in the first ordered pair (1)

x2 is x in the second ordered pair (4)

x1 is x in the first ordered pair (-1)

                = (-9 - 1) / (4 +1)

                 = -10/5

             m = -2

Now plug m (-2), y1 (1), and x1 (-1) into the point slope form

y - 1 = -2 (x - -1)

y - 1 = -2 (x + 1)

Answer: The value of x=1.

Measure of CD =1 unit.

Step-by-step explanation:

Given: Segment EC bisects segment AD at C.

That means , EC divided AD into two equal parts AC and CD,

i.e. [tex]AC=\dfrac{AD}{2}[/tex]  

Also it is given that [tex]AD = 6x - 4[/tex] and [tex]AC = 4x - 3.[/tex]

then, we have

[tex]4x-3=\dfrac{6x-4}{2}\\\\\Rightarrow\ 4x-3= 3x-2\\\\\Rightarrow\ 4x-3x=-2+3\\\\\Rightarrow\ x= 1[/tex]

So, the value of x=1.

Now,  CD = AC = 4(1)-3 =4-3 =1 unit.

Hence, Measure of CD =1 unit.
