The average of 5 numbers is 23. If the 4 numbers are 18, 27,22 and 20 then find the 5th number?

Answers

Answer 1

Answer:

5th number = 28

Step-by-step explanation:

23*5 = 115

The sum of the 5 numbers is

115

Then:

18 + 27 + 22 + 20 + a = 115

a = 5ft number

87 + a = 115

a = 115 - 87

a = 28

Check:

(18+27+22+20+28)/5 = 23

115/5 = 23

Answer 2

Answer: The fifth number is 28

Step-by-step explanation:

All numbers = 18, 27, 22, 20, x

5th number is x


So,  
[tex]\frac{18+27+22+20+x}{5}[/tex]  = 23  (as the there are 5 numbers)

=> [tex]\frac{87+x}{5}[/tex] = 23

=> 87+x = 115

=> x = 28

Therefore the 5th number is 28

Jeff had $20. He spent 3/8 of his money on lunch. How much money does Jeff have left?

A. $12.50

B. $7.50

C. $8.25

D. $16.75

Answers

Answer: Option A, $12.50

Step-by-step explanation: Jeff spent 3/8 of his money, which can be represented by the equation as follows:

1 - 3/8 = 5/8

where 1 represents 8/8, or $20, and 5/8 represents the remainder of Jeff's money.

To find how much money Jeff has left, we can multiply his initial investment by 5/8:

$20 × 5/8 = $100/8, or $12.50

Hence, Jeff has $12.50 leftover, which is represented by option A.

20 divided by 3/8 is 7.5

Jeff has $7.50

The perimetre of a rectangle is 38cm length is 12.5, What is the Area?..

Answers

Answer:

[tex]\boxed{\mathtt{Area = 81.25cm^{2}}}[/tex]

Step-by-step explanation:

[tex]\textsf{For this problem, we are asked to solve for the \underline{Area} of a Rectangle.}[/tex]

[tex]\textsf{We are given the \underline{Perimeter}, and the \underline{Length}.}[/tex]

[tex]\textsf{We should begin by identifying the formulas for Perimeter and Area.}[/tex]

[tex]\mathtt{Perimeter = Length + Length + WIdth + Width}[/tex]

[tex]\mathtt{Area = Length \times Width}[/tex]

[tex]\textsf{Because we're given the Perimeter and the Length, we can identify the Width.}[/tex]

[tex]\large\underline{\textsf{Substitute:}}[/tex]

[tex]\mathtt{38 cm = 12.5 + 12.5 + Width + Width}[/tex]

[tex]\large\underline{\textsf{Combine Like Terms:}}[/tex]

[tex]\mathtt{38 cm = 25 cm+ 2(Width)}[/tex]

[tex]\large\underline{\textsf{Subtract 25 from both sides:}}[/tex]

[tex]\mathtt{13 cm = 2(Width)}[/tex]

[tex]\large\underline{\textsf{Divide By 2:}}[/tex]

[tex]\mathtt{6.5 cm = Width}[/tex]

[tex]\textsf{Now that we know the Width, we can identify the Area.}[/tex]

[tex]\large\underline{\textsf{Substitute:}}[/tex]

[tex]\mathtt{Area = 12.5 cm \times 6.5cm}[/tex]

[tex]\boxed{\mathtt{Area = 81.25cm^{2}}}[/tex]

The angles which are formed inside the two parallel lines, when intersected by a transversal, are equal to its alternate pairs.

q and t are alternate interior

r and k are alternate interior

W is 79

The mistake he made is equating an alternate interior angle to an alternate exterior angle

1 .When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These angles are always equal.

Alternate exterior angles are those angles that have different vertices, lie on the alternate sides of the transversal, and are exterior to the lines. When a transversal intersects two parallel lines, the alternate exterior angles formed are always equal.

2. check the picture for translation of the angles

The box plots below show the average daily temperatures in April and October for a U.S. city:



What can you tell about the means for these two months?

The mean for April is higher than October's mean.
There is no way of telling what the means are.
The low median for October pulls its mean below April's mean.
The high range for October pulls its mean above April's mean.

Answers

Answer:

A mean in math is the average of a data set, found by adding all numbers together and then dividing the sum of the numbers by the number of numbers. For example, with the data set: 8, 9, 5, 6, 7, the mean is 7, as 8 + 9 + 5 + 6 + 7 = 35, 35/5 = 7. So, assuming that's the type of "Mean" your talking about, there is no way of telling what the means are seeing as the picture only shows the averages.

milk seller had 23.45 L. milk. He added 3.625 L water to it. How much was the quantity of the resultant mixture?

Answers

Answer:

Volume of milk = 23.45 L

Volume of water = 3.625 L

Total volume of the mixture = Volume of milk + Volume of water

Total volume of the mixture = 23.45 L + 3.625 L

Total volume of the mixture = 27.075 L

Therefore, the quantity of the resultant mixture is 27.075 L.

Answer is 27.075 because the milk is 23.45 L then you add the water which is 3.625 L

Gianna and her family went for a drive. They traveled 175 miles in 3 hours. What was their average speed?


Would you write an inequality or an equation?

Answers

To find the average speed, we divide the total distance traveled by the time taken:

Average speed = Total distance ÷ Time taken

Therefore, Gianna and her family's average speed is:

Average speed = 175 miles ÷ 3 hours = 58.33 miles per hour (rounded to two decimal places)

We use an equation to solve this problem.

Equation: Average speed = Total distance ÷ Time taken

Where:

Total distance = 175 miles

Time taken = 3 hours

Substituting these values into the equation, we get:

Average speed = 175 miles ÷ 3 hours

Therefore, the answer is an equation:

Average speed = 175 miles ÷ 3 hours

The answer would be 175 divided by 3.

A student is buying thank you cards. Each than you card cost $2. The equation t = 2c represents the total cost, t, this student will spend to buy c cards. Which variable is the independent variable in the equation? Which is the dependent variable? Explain how you know.

Answers

Answer:

t is dependent and c is independent because if c increases so will t

The independent variable is the variable that is being manipulated or controlled in an experiment, and it is typically plotted on the x-axis of a graph. In this equation, "c" represents the number of thank you cards being purchased, which is something that the student can control or manipulate. The student can decide to buy 1 card, 2 cards, 3 cards, etc., and the cost will vary accordingly.

The dependent variable, on the other hand, is the variable that is being measured or observed, and it is typically plotted on the y-axis of a graph. In this equation, "t" represents the total cost of the thank you cards, which is something that depends on the number of cards being purchased. The cost is not something that the student can control directly, but rather it is determined by the number of cards being purchased.

Therefore, in the equation t = 2c, "c" is the independent variable because it is being manipulated by the student, and "t" is the dependent variable because it depends on the value of "c".

How much alcohol must a pharmacist add to 10 cm^3 of an 8% alcohol solution to strengthen it to an 80% solution? PLS ANSWER URGENT THANKS

Answers

The pharmacist must add [tex]36 cm^3[/tex] of pure alcohol to the [tex]10 cm^3[/tex] of 8% alcohol solution to obtain an 80% alcohol solution.

What is alcohol ?

Alcohol, also known as ethanol is a clear, colorless liquid that is produced by the fermentation of sugars and carbohydrates by yeasts.

Let's start by writing down the equation that relates the amount of alcohol in the original 8% solution to the amount of alcohol in the final 80% solution:

[tex]0.08 x 10 cm^3[/tex] [tex]+ x = 0.80 x (10 cm^3 + x)[/tex]

Here, x represents the amount of pure alcohol that we need to add to the [tex]10 cm^3[/tex] of 8% solution to obtain the desired 80% solution.

The left-hand side of the equation represents the amount of alcohol in the original solution (which is 8% alcohol), while the right-hand side represents the amount of alcohol in the final solution (which is 80% alcohol).

Now we can solve for x:

[tex]0.08 x 10 cm^3 + x = 0.80 x (10 cm^3 + x)[/tex]

[tex]0.8 cm^3 + x = 8 cm^3 + 0.8x[/tex]

[tex]0.2x = 7.2 cm^3[/tex]

[tex]x = 36 cm^3[/tex]

Therefore, the pharmacist must add [tex]36 cm^3[/tex] of pure alcohol to the [tex]10 cm^3[/tex] of 8% alcohol solution to obtain an 80% alcohol solution.

The singh family orderd a large pizza with a diameter of 20 inches for dinner. If one of the members ate one-eighth of the pizza, how many square inches of pizza are remaining? (use 3.14 for pi)

Answers

Answer:

275.5 square inches of pizza remaining

Step-by-step explanation:

The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle.

The diameter of the pizza is 20 inches, so the radius is half of that, or 10 inches.

The area of the entire pizza is:

A = πr^2 = 3.14 x 10^2 = 314 square inches.

If one member of the family ate one eighth of the pizza, then the amount of pizza remaining is 7/8 of the original amount.

The remaining area of the pizza is:

(7/8) x 314 = 275.5 square inches.

Therefore, there are 275.5 square inches of pizza remaining.
