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

The hole for a support needs to be 4 feet deep. It is currently 1 foot 6 inches deep. How much deeper must the hole be? Show two ways to solve this problem. Use the conversion factor 12/1.
The hole needs to be __ in deeper
Answers
Answer:
4 feet = 48 inches
1 foot 6 inches = 18 inches
The hole needs to be 30 inches deeper.
4 feet - 1 1/2 feet = 2 1/2 feet = 30 inches
The hole needs to be 2 1/2 feet = 30 inches deeper.
Which is a way to find the equation of a line that best fits this data?
Answers
A way to find the equation of a line that best fits this data include the following: A. Use the coordinates of points B and D to find the slope and then the equation of the line that passes through them.
What are the characteristics of a line of best fit?In Mathematics, there are different characteristics that are used for determining the line of best fit on a scatter plot and these include the following:
The line should be very close to the data points as much as possible.The number of data points that are above the line should be equal to the number of data points that are below the line.By critically observing the scatter plot using the aforementioned characteristics, we can reasonably infer and logically deduce that data points B and D represent the line of best fit because they are in a linear pattern.

A bullet train covers 895.65km in 5 hours. What distance will it cover in an hour?
Answers
Answer:
179.13km/1hr (or 179.13 km)
Step-by-step explanation:
Distance is speed/time.
Using that, we can input
895.65 KM / 5 H
To convert 5 hours to one hour to find the speed, we need to divide both 5 and 895.65 by 5:
179.13km/1hr
which is your answer :)
Step-by-step explanation:
5 hours = 895.65km
Let 1hrs = x
:895.65/5 = x
=179.13= x
so, therefore 1hours bullet train covers 179.13km

Answer: "B. -5"
Step-by-step explanation:
STEP 1: Plug -5 into the equation where "X" currently is; 10 (-5) - 5 = -55
STEP 2: Multiply 10 (-5) [-50].
STEP 3: Update the equation to reflect Step 2; -50 - 5 = -55
STEP 4: Subtract 5 from -50 [-55].
STEP 5: Update the equation to reflect Step 4; -55 = -55
It is true that -55 = -55, so, therefore, the answer is "B. -5."

there r other ways you can do it tho :)
Answer: 20:60, 12:36, 2:6.
Step-by-step explanation: 4:12 = 1:3. The ratio 4:12 is equal to 1:3. which means that the second number (sn) is 3 times the first number (fn). sn = 3 * fn. The first equation: sn = 3 * 20. 3 * 20 is 60, so the second number would be 60. The second equation: 36 = 3 * fn. Divide each side by three, so the equation reads 12 = fn. The last equation: 6 = 3 * fn. Divide each side by three, so the equation reads 2 = fn.
A town is designing a rectangular park that will be 600 feet wide by 1000 feet long. On a scale drawing, the dimensions of the park are 12 inches wide by 20 inches long. A rectangular area of the park for swing sets is 0.5 inch wide by 2 inches long on the scale drawing.
What is the actual length of the swing set area of the park?
Enter your answer in the box.
The actual length of the swing set area of the park is ______ feet.
Answers
Answer: The dimensions of the park on the scale drawing is 12 inches and 20 inches.
Dimension
Actual dimensions:
Park = 600 feet by 1000 feet
Swing set = 25 feet by 100 feet
Swing set on the scale drawing= 0.5 inch by 2 inches
Hence:
Dimension of park on drawing:
Width = 600×1/50
Width = 12inches
Length = 1000×1/50
Length= 20inches
In conclusion the dimensions of the park on the scale drawing are 12 inches and 20 inches.

72° + angle b = 90°

Choose...

square units.
The area of the triangle is half the area of the rectangle, so the area of the triangle is
Choose...
square units.
Answers
Answer:
Length of the rectangle = 5 units
Width of rectangle = 4 units
Area of rectangle = 20 units
Area of triangle = 10 units
Step-by-step explanation:
Since I don't know the answer choices, I am assuming the base of the triangle as the length and the height as the width. Check your answer choices and switch 4 and 5 if it is the other way around
Using the graph
The rectangle formed by rotating the triangle and placing it along the original rectangle will have a length(base)
= length of the base of the triangle
= 5 units
The width of the rectangle will be the same as the height of the rectangle = 4 units
The area = length x width = 5 x 4 = 20 units
Area of triangle = half area of rectangle = 20/2 = 10 units

Find the circumradius of the triangle(side lengths 29, 29, 40)

Answers
Answer:
See explanation below
Step-by-step explanation:
△ABC is isosceles right triangle because AB = BC = 29. Therefore the height of △ABC (which we can call AD) will bisect base AC at 90 degrees.
We can calculate the height of AD using Pythagorean theorem with BC is the hypotenuse (which is 29), and the side DC (equals 1/2 AC = 40/2 = 20)
=> BC^2 = BD^2 + DC^2
=> BD^2 = BC^2 - DC^2 = 29^2 - 20^2 = 841 - 400 = 441
=> BC = 21
so area of △ABC = hb/2 = (21 x 20)/2 = 210
To find the circumradius, we need to use formula A = abc/4R
=> R = abc/4A
R = (29)(29)(40)/(4 x 210) = (29 x 29 x 10)/210 = 40.05
If you find this helpful, please give brainliest.
20 units is the circumradius of the triangle which has side lengths 29, 29, 40.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
To find the circumradius of a triangle with side lengths a, b, and c, use the formula:
circumradius = abc / 4Δ
where Δ is the area of the triangle.
To find the area of the triangle, use Heron's formula:
s = (a + b + c) / 2
Δ = √(s(s-a)(s-b)(s-c))
where s is the semiperimeter of the triangle.
In this case, the side lengths of the triangle are 29, 29, and 40. The semiperimeter is:
s = (29 + 29 + 40) / 2 = 49
Using Heron's formula, the area of the triangle is:
Δ = √(49(49-29)(49-29)(49-40))
= √(49×20×20×9)
=√176400
= 420
Now, using the formula for the circumradius, we have:
circumradius = abc / 4Δ
= (29×29×40) / (4×420)
=20 units
Therefore, the circumradius of the triangle is 20 units
