5/6 is equal to all of these
5/6 = 10/12 = 15/18 = 20/24
= 25/30 = 30/36 = 35/42 = 40/48
= 45/54 = 50/60 = 55/66 = 60/72
= 65/78 = 70/84 = 75/90 = 80/96

= 265/318 = 270/324 = 275/330 = 280/336
= 285/342 = 290/348 = 295/354 = 300/360
= 305/366 = 310/372 = 315/378 = 320/384
= 325/390 = 330/396 = 335/402 = 340/408
= 345/414 = 350/420 = 355/426 = 360/432

Find the measure of each marked angle. Assume the lines are parallel.
(2x - 30)° =
(x+3)° =
Answer:
Measure of each angle = 36°
Step-by-step explanation:
[tex](2x - 30) \degree = (x + 3) \degree \\ (alternate \: \angle \: s) \\ \\ 2x - 30 = x + 3 \\ \\ 2x - x = 30 + 3 \\ \\ x = 33 \\ \\ (2x - 30) \degree \\ = (2 \times 33 - 30)\degree \\ = (66 - 30)\degree \\ = 36 \degree \\ \\ (x + 3) \degree \\ = (33 + 3) \degree \\ = 36\degree[/tex]
The value of x will be equal to 33.
What are alternate exterior angles?According to the alternate exterior angle theorem, the exterior angles created on either side of a transversal when two parallel lines intersect are equal. The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Given angles (2x - 30)° and (x+3)° are alternate exterior angles so these two angles will be equal to equal to each other.
(2x - 30)° = (x+3)°
Separate all the like terms and calculate the value of x:-
(2x - 30)° = (x+3)°
2x - x = 33 + 3
x = 33
Therefore, the value of x will be equal to 33.

7) Find the sample standard deviation. 22 29 21 24 27 28 25 36
Answer:
26.5
Step-by-step explanation:
The standard deviation of 22, 29, 21, 24, 27, 28, 25, 36 is 19.75.
What is standard deviation ?"The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance. The standard deviation is calculated as the square root of variance by determining each data point's deviation relative to the mean."
"Standard deviation is an especially useful tool in investing and trading strategies as it helps measure market and security volatility—and predict performance trends. As it relates to investing, for example, an index fund is likely to have a low standard deviation versus its benchmark index, as the fund's goal is to replicate the index."
The given numbers are 22, 29, 21, 24, 27, 28, 25, 36.
The formula for standard deviation is [tex]\sqrt({ $\sum_{n=1}^{n} (xi - mean)^2/n )= 1$}[/tex]
Finding mean of given numbers = 22+29+21+24+27+28+25+36/8 = 26.5
Now for standard deviation =[tex]\sqrt((22-26.5)^2 + (26.5-29)^2 + (26.5-21)^2+(26.5-24)^2+(26.5-27)^2+(26.5-28)^2+(26.5-25)^2+(26.5-36)^2/8 )[/tex]
= 19.75
Hence, the standard deviation of the given numbers is 19.75

9/2 divided by 2/9 this is dividing fractions
Answer:
4/81
Step-by-step explanation:
Don't ask i just know
-Too much work to explain
The division of of 9/2 by 2/9 is equal to 81/4.
To divide fractions, multiply the first fraction by the reciprocal of the second fraction.
In this case, we need to divide 9/2 by 2/9.
Dividing fractions: (a/b) ÷ (c/d) = (a/b) * (d/c)
So, we can rewrite the expression as:
(9/2) ÷ (2/9) = (9/2) * (9/2)
Now, let's perform the multiplication:
(9/2) * (9/2) = (9 * 9) / (2 * 2) = 81/4
Therefore, the division gives 81/4.

Henry has a 88 average after 7 assignments in his class. He would like
to get an A in the class, which requires an 89.5% What grade is required
on the next assignment so he can get an A
Answer: He need to score 100 in next assignment to can get an A.
Step-by-step explanation:
Given: Average marks till now = 88%
Average = (sum) divided by (Number of observations)
Here, number of assignments =7
So, [tex]88=\dfrac{(sum)}{7}\Rightarrow\ sum =88\times7= 616[/tex] (i)
After next assignment, number of assignments = 8
Required Average = 89.5
[tex]89.5=\dfrac{sum}{8}\Rightarrow\ sum = 89.5\times8= 716[/tex] (ii)

Lin ran 2 3/4 miles in 2/5 of an hour, Noah ran 8 2/3 miles in 4/3 of an hour. How long would it take Lin and Noah to run 1 mile at that rate?
Answer:
Step-by-step explanation:
Lin
Distance = 2 3/4 miles
Time = 2/5 hours
= distance / time
= 2 3/4 ÷ 2/5
= 11/4 × 5/2
= 55/8
= 6 7/8
It would take Lin 6 7/8 hour to run 1 mile at a constant rate
Noah
Distance = 8 2/3 miles
Time = 4/3 hour
= distance / time
= 8 2/3 ÷ 4/3
= 26/3 × 3/4
= 26/4
= 13/2
= 6 1/2
It would take Noah 6 1/2 hour to run 1 mile at a constant rate
