Can someone help me find the value of n? For this problem
Answer:
n = 129
Step-by-step explanation:
Reference angle = 60°
Hypotenuse = n
Adjacent side = 64.5
Apply CAH, which is:
Cos 60 = adj/hyp
Cos 60 = 64.5/n
Multiply both sides by n
n×Cos 60 = 64.5
Divide both sides by cos 60
n = 64.5/Cos 60
n = 64.5/0.5
n = 129

A coffee shop sells 5 different types of cake and 6 different kind of drinks. Ruby wants to order a cake and a drink. How many different combinations of cake and drink could she choose?
Answer:
She could choose 30 different combinations of cake and drink
Step-by-step explanation:
A coffee shop sells 5 different types of cake and 6 different kind of drinks.
This means that:
For each type of cake, there are 6 different kind of drink.
At all, there are 5 different types of cake.
So
6*5 = 30
She could choose 30 different combinations of cake and drink

What's the correct formula for this function?
Answer:
Option C. y = -2x + 3
Step-by-step explanation:
When we look at this function we see that it has a negative slope and the y-intercept is equal to (0,3). From this we know that the function we are looking for will be looking like...
y = mx + 3
And as I said earlier since the slope is negative, the only right option is this case will be Option C
Answer:
The correct anwer is (C) : y = - 2x + 3

Pentagon ABCDE is similar to pentagon RSTUV . The perimeter of pentagon ABCDE is 36.8 centimeters.
What is the length of ST ?
19.8 cm
18 cm
25.8 cm
15 cm
Answer:
ST = 15 cm
Step-by-step explanation:
find BC first by adding four other sides and subtracting from 36.8
sum of 4 sides is 30.8, so BC = 6
Now find ST by creating a proportion from corresponding sides:
BC / ST = DE / UV
6 / ST = 13.2 / 33
Cross-multiply:
13.2ST = 198
ST = 198/13.2
ST = 15

Answer:
8606.4 Miles
Step-by-step explanation:
Since we know that each lap was the same length, we can do 137,702.4/16 and get 8606.4
Answer:
8606.4

In a manufacturing plant, a work center is a specific production facility that consists of one or more people and or machines and is treated as one unit for the purposes of capacity requirements planning and job scheduling. If the jobs arriveat a particular work center at a faster rate than they depart, the work center impedes the overall production process and is referred to as a bottleneck. This sample was collected by an operations manager for use in investigating a potential bottleneck work center. There are 315 hours in the work week when items can come into the work center. The manager selects every 15th hour and counts how many items come into the work center during that hour. What type of sample is this?
Answer:
Systematic sampling
Step-by-step explanation:
Systematic sampling is a sampling technique in which the first sample selection is a random selection but other subsequent selection of samples occurs within a fixed sampling interval. The determination of this interval is based on the division of the population size by sample size.
Let assume that, our first random selection is [tex]i^{th}[/tex] unit, then the other fixed selection occurs at a fixed sampling interval of k.
Therefore, using systematic sampling method, the sampling unit will be every [tex]k^{th}[/tex] unit after the [tex]i^{th}[/tex] unit.
From the question given:
We notice that the manager selects a sampling unit every 15th hour. This tells us that he is taking the sampling unit by the usage of a fixed time interval.
Hence, this appears to be a systematic sample.

How to subtract -2 1/6-2/3
Answer:
Conversion a mixed number 2 1/6
to a improper fraction: 2 1/6 = 2 1/6
= 2 · 6 + 1/6
= 12 + 1/6
= 13/6
Multiply the whole number 2 by the denominator 6. Whole number 2 equally 2 * 6/6 = 12/6
To find new numerator: 13/6 - 2/3= 13/6 - 2 · 2/ 3 · 2 = 13/6- 4/6= 13 - 4/6= 9/6= 3 · 3/3 · 2= 3/2
Add the answer from previous step 12 to the numerator 1. New numerator is 12 + 1 = 13
Write a previous answer (new numerator 13) over the denominator 6.
Two and one sixth is thirteen sixths
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(6, 3) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 3 = 18. In the next intermediate step , cancel by a common factor of 3 gives 3/2
.
In words - thirteen sixths minus two thirds = three halfs.
I'm not sure if this is right but if it's not I did math for nothing-.
What is the product of 3.6 x 4.2
How did you find it.
Answer:
15.12
Step-by-step explanation:
3.6 x 4.2
first aline the decmials like you would regularly do to multiply.
Then multiply 2 x 6=12 and then 2 x 3=6 and put them down were you would already do noramly multiplying.
and then muliply 4x6=24 and 4x3=12 and do the same thing as you would do normaly and then add 72 and 144 to get 1512 and then count your decmail placing. which is 2 placeing in total which makes 1512 into 15.12
and now you done!
Example of how it should look...
3 . 6
× 4 . 2
+ 7 . 2
+ 1 4 4
= 1 5 1 2

The probability that I will go sailing today AND the fair six-sided die will come up even on the next roll is .3.
these events are independent, what is the probability that I will go sailing today?
Answer:
Step-by-step explanation:
Let us consider P(A) to be the probability for the fact that I will go for sailing today
Likewise, P(B) will be the probability of a die to come up on an even number in the next roll.
Now, according to the question,
P(A and B) = 0.3
It is known to us that the probability of a die to land with an even number on its side up =
Moreover, we are given with the fact that both P(A) and P(B) are independent.
∴ P(A and B) = P(A) × P(B)
⇒ 0.3 = P(A) × 0.5
⇒ P(A) = = 0.6
pls this is due soon helopppp

When a card is selected from a deck, find the probability of getting a. A club b. A face card or a heart c. A 6 and a spade d. A king e. A red card
Answer:
Kindly check explanation
Step-by-step explanation:
Number of clubs = 13
Number of face cards = 12
Number of hearts = 13
Number of King's = 4
Number of reds = 26
Number of spade = 13
Number of 6's = 4
Total possible outcomes = total number of cards = 52
Probability = required outcome / Total possible outcomes
1.) P(A club) = 13 / 52
2.) P(face card or heart) =
p(face card) + p(heart)
12 / 52 + 13/52
= (12 + 13) / 52 = 25 /52
3.)
(A 6 and a spade)
4/52 * 13/52
= 52 / 2704
= 1/52
4.) A king
P(king) = 4 /52 = 1/13
5) A red
P(red) = 26 / 52 = 1/2
