Answer:
16.4
Step-by-step explanation:
The law of cosines is useful here. It tells you ...
b^2 = a^2 + c^2 -2ac·cos(B)
b^2 = 22^2 +10^2 -2·22·10·cos(44°)
b^2 ≈ 267.49
b ≈ √267.49 ≈ 16.35514
b ≈ 16.4

Michael has 3 quarters, 2 dimes, and 3 nickels in his
pocket. He randomly draws two coins from his pocket,
one at a time, and they are both dimes. He says the
probability of that occurring is because 2 of the 8
coins are dimes. Is he correct? Explain.
Answers
My Answer:
The events are dependent.
The size of the original sample space is 8. It changes to 7 after the first dime is chosen.
The probability of picking the first dime is 2/8.
The probability of picking the second dime is 1/7
To find the probability of the compound event, multiply the probabilities.
I got it correct, on edge 2020/2021
Answer:
No. Choosing two dimes are dependent events. The probability of choosing the first dime is 14 and the probability of choosing the second dime is 17 . The probability that both coins are dimes is (14)(17) = 128.

A company prints 4580 copies of the same book. The number of pages in the book, including the cover pages, is 79. What is the total number of pages, including the cover pages, that the company prints?
Answers
Answer: 361,820 pages
Step-by-step explanation:
The company prints 4,580 copies of the same book and it has 79 pages including cover pages.
The total number of pages the company prints therefore is:
= 4,580 * 79
= 361,820 pages
The values of m and n are whole numbers greater than 1. Which is true about the quotient
Answers
Answer:
"The expression will always equal m" is true about the quotient of [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex]
Step-by-step explanation:
Let us solve the question
∵ The expression is [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex]
→ In the division of fractions, we change the division to multiplication
and reciprocal the fraction after the division sign
∵ The reciprocal of [tex]\frac{1}{n}[/tex] is [tex]\frac{n}{1}[/tex]
∴ [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex] = [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex]
→ In the multiplication of fractions, we can simplify the terms in
the numerators by the terms in the denominators
∵ There is n in the numerator and denominator
∴ Cancel n up and down
∴ [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex] = [tex]\frac{m}{1}[/tex]
∴ [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex] = m
∴ [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex] = m
∴ The quotient is m
∴ The expression will always equal m

line a passes through points (5,8) and (10,6). line b is perpendicular to a. what is the slope of line b?
Answers
Answer:
2/5
Step-by-step explanation:
First, we need to find the slope of line a. To do this, we subtract the two y values and then the two x values and divide these two differences.
10-5=5
6-8=-2
5/-2= -5/2
A perpendicular line's slope will always be equal to the negative reciprocal of the intersects. So, we just flip the numerator and denominator and then add a negative to our first slope to get the slope of line b.

I got some money for my birthday. I save and spend in the ratio 2:3. I save £32. How much money did I receive for my birthday?
Answers
Answer:
80 i think
Step-by-step explanation:
32.3=80
Step-by-step explanation:
Amount of money saved : spent = 2 : 3.
Since amount of money saved = £32,
Amount of money spent = £32 * (3/2) = £48.
Total amount of money = £32 + £48 = £80.
Therefore I received £80 for my birthday.

Answers
Answer:
a)
(i) 43, 56
(ii) -1,3
b)-27
c) -21 +4n
Step-by-step explanation:
For a,i, you can see that it decreses by 7 each time so you subtract 7 from 50 to get 43, then you subtract 7 from that to get 56. For a,ii it increases by 4 each time so you add 4 to -5 to get -1, then add 4 to that to get 3. For b, because it is the 15th term you are looking for, you can plug 15 into the equation as n so 78-7n to 78- 7*15, 78-105, -27. For c, you know that each time it increases by 4, so you know you add 4n, and then for the base, you have to find the term before -17 so you subtract 4 to get -21. Put it together and get -21+4n.

Write an expression for the slope of the line in the graph using the letters u,v,s, and t.
Answers
Answer:
We conclude that the slope between (s, t) and (u, v):
slope = [v - t] / [u - s]Step-by-step explanation:
We can find the slope between two points (x₁, y₁) and (x₂, y₂) using the formula
slope = [y₂ - y₁] / [x₂ - x₁]
In our case, the two points are
(x₁, y₁) = (s, t)
(x₂, y₂) = (u, v)
Thus, the slope between (s, t) and (u, v)
slope = [v - t] / [u - s]
Therefore, we conclude that the slope between (s, t) and (u, v):
slope = [v - t] / [u - s].............. Help! Easy math practice

to find the value of x. we are going to use the sine rule
It states that the ratio of the sine of an angle to the measure of the side facing the angle is fixed for a triangle
In this case;
11/ sin 27 = x/ sin 34
x = 11 sin 34/sin 27
x = 13.6
