Find the geometric mean of 16 and 36. Write your answer in simplest form. The geometric mean is
Answer:
Step-by-step explanation:
the geo. mean is the nth root of the product of n numbers
Here there are two numbers; geo. mean is the square root of their product
g = √(16 * 36)
g = 4 * 6
g = 24
Geometric mean is the mean which is the average of a set of a product.
The geometric mean of the given numbers is 24.
What is geometric mean?Geometric mean is the mean which is the average of a set of a product.
It can be given as,
[tex](\prod_{i=1}^{n}x_i)^{1/n}=\sqrt[n]{x_1\times x_2\times x_3...........x_n}[/tex]
Here [tex]x_i[/tex] is the values of the average and [tex]n[/tex] is the number of values.
Given information-
The numbers given in the problem is 16 and 36.
The Geometric mean for the number 16 and 36 has to find out.
Use the above formula to find the geometric mean for the number 16 and 36. Thus,
[tex]\prod=\sqrt{16\times36}[/tex]
[tex]\prod=\sqrt{576}\\\prod=24[/tex]

Find U of trapezoid TUVS
Answer:
[tex]m<U = 103[/tex]
Step-by-step explanation:
The given trapezoid is an isosceles trapezoid, meaning that the two legs of the trapezoid (sides that intersect the parallel lines) are congruent. One of the proprieties of an isosceles trapezoid is that the opposite angles are supplementary, meaning that the sum of the opposite angles is 180. One can apply this theorem here by stating the following,
[tex]m<S + m<U = 180[/tex]
Substitute,
[tex]77+m<U = 180[/tex]
Inverse operations,
[tex]77+m<U = 180[/tex]
[tex]-77[/tex]
[tex]m<U = 103[/tex]
Answer:
[tex] m\angle U = 103\degree[/tex]
Step-by-step explanation:
[tex] m\angle T + m\angle S = 180\degree [/tex] (interior angles on the same side of transversal)
[tex] m\angle T + 77\degree = 180\degree [/tex]
[tex] m\angle T = 180\degree- 77\degree[/tex]
[tex] m\angle T = 103\degree[/tex]
[tex] m\angle U =m\angle T [/tex]
(base angles of an isosceles trapezoid)
[tex] m\angle U = 103\degree[/tex]
Anyone please help I just need help with this problem
Answer:
21.91 meters
Step-by-step explanation:
Since they already give you the hypotenuse, you will find the other missing side using this formula:
A= [tex]\sqrt{c^2 - b^2}[/tex]
So c² = 1,156
and b² = 676
1156 - 676 = 480
------
The square root of 480 is around 21.91
Let's double check, to double check, pretend that you don't know the hypotenuse, but you know the a and b sides.
So: 480.05 + 676 = 1,156.05
[tex]\sqrt{1156.05}[/tex] ≈ 34

Mila and Nadia have R480 between them.
Mila has 7 times as much as Nadia.
How much does each of them have?
Answer:
Mila= 420 Nadia= 60
Step-by-step explanation:
Let's call Mila 7x. And x to Nadia. The two of them had a total of 480s.
Then we say 7x + x. Their total is 8x. So 480 = 8x. We divide both sides by 8. Here x = 60. Since Mila is 7x, we find Mila as 7.60 = 420, and since Nadia as x, we find Nadia as 1.60 = 60.

Find the missing side.
6 is A^2
10 is B^2
what is the missing side
Answer:
8
Step-by-step explanation:
This is a right triangle, which fits the Pythagorean Theorem, a^2 +b^2 = c^2. The variables a, b, and c all are sides of the triangle, while a and b are the two legs and c is the hypothenuse.
In this problem, we see that 6 and x are the legs and 10 is the hypothenuse. We put 6 as "a" and x as "b" (but it doesn't matter which is a and b) and 10 is c. Therefore, we have the equation:
6^2 + x^2 = 10^2
which further simplifies to:
36 + x^2 = 100
x^2 = 64
and so x would equal 8 (or -8, but it is impossible to have a side length of -8).
Therefore, the missing side is 8.
Answer:
The missing side is x=8
Step-by-step explanation:
The missing side equation is a²+b²=c²
So we plug in 6²+b²=10²
This gives us 8²
The formula for the circumference, C, of a circle with given radius, r, is C = 2nr.
What is the circumference of a circle with a radius of 3 1-2 meters?
(Use 21
22
as an estimate for n.)
A. 7 meters
B. 11 meters
C. 22 meters
D. 44 meters
Answer:
C. 22
Step-by-step explanation:
C = circumference
n (pi) = 22/7
r = 3 1 /2
Plug in the numbers for each variable.
C = 2x (22/7) x (3 1/2)
Change the mixed number inIto an improper fraction by multiplying 3 x 2 and adding the 1 which gives us 7 over 2 because 2 is our denominator so, 3 1/2 = 7/2. It also helps to have 1 as the denominator for 2.
C = (2/1) x (22/7) x (7/2)
Lastly, just multiply the numerators across which give us 308 then multiply the denominators across which gives us 14, so then we divide 308 by 14 and get 22.

Kristina rides her bicycle 384.25 miles over 29 weeks to and from her job. How many miles does she ride each week to and from her job if she rides the same amount each week?
Question: Mai had $14.50. She spent $4.35 at the snack bar and $5.25 at the arcade. What is the exact amount of money Mai has left?
Answer: $4.90
Steps: Step 1: Find operation: The operation in this problem is subtraction because words such as "spent" means that she used money, meaning we subtract.
Step 2: Figure out order of numbers: Now that we know that the operation is subtraction, we need to know what numbers to subtract. The problem says that Mai had $14.50, which means that this is the total amount of money she had when she started. Spent means that Mai used money, so this means that we subtract like this: $14.50-$4.35-$5.25.
Step 3: Subtract: Now that we know what operation to use, and what order to use the numbers, we can finish the problem:
$14.90 - $ 4.35 ------------------- $10.15 - $ 5.25 -------------------- $4.90--------------------------------------------------------------------------------------------------------------
Question: Kristina rides her bicycle 384.25 miles over 29 weeks to and from her job. How many miles does she ride each week to and from her job if she rides the same amount each week?
Answer: 13.25
Steps: 1: Find operation: To solve this question, we need to find the operation. Words such as "same amount each week" mean that this is division.
Step 2: Figure out order of numbers: Now, we need to figure out what to divide by. We divide 384.25 by 29 because it say that she rides 384.25 miles over 29 weeks.
Step 3: Divide: Now, we will solve the equation: 384.25 divided by 29 is 13.25, so the answer is 13.25.
Hope this helps you!
P.s. Sorry I could not show how to divide 384.25 by 29.
