Answer:
2/15
Step-by-step explanation:
LCD(4/5, 2/3) = 15
so then when you find the Least Common Denominator it will be 12/15-10/15 and then it equals 2/15

The number of views on a viral video can be modeled by the function Q(t)=410(5)^{2t}.Q(t)=410(5) 2t . Write an equivalent function of the form Q(t)=ab^t.Q(t)=ab t .
Answer: Q(t) = 410*(5)^(2t) = 410*(5^2)^t = 410*(25)^t
Step-by-step explanation:
We start with the equation:
Q(t) = 410*(5)^(2t)
And we want to rewrite this in the form:
Q(t) = a*b^t
To do this, we need to use the property:
(a^x)^y = a^(x*y)
Using this, we can rewrite:
Q(t) = 410*(5)^(2t) = 410*(5^2)^t = 410*(25)^t
And this is the form that we wanted:
Answer:
13120(16)^t

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.
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.

Explain the importance of putting your data set in order from least to greatest
Answer:
The mean may not be a fair representation of the date
Step-by-step explain the average is easily influenced by outliers (very small or large values in the data set that are not typical). The median is another way to measure the center of a numerical data set. ... Thus, the median is truly the middle of the data set.
If Mr. Jones buys paddles for $35 instead of $50 and uses the same percent increase on price how many paddles most Mr. Jones sell for the total paddle sales before tax and to be at least $250 explain your answer
Answer: 4 paddles
Step-by-step explanation:
Mr. Jones buys the paddle for $35 and sells at 180% of the purchase price:
= 35 * 180/100
= $63
For the number of paddle sales to be at least $250, he should sell:
= 250/63
= 3.97
= 4 paddles
How many centimetres are there

Write an expression for the slope of the line in the graph using the letters u,v,s, and t.
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]line a passes through points (5,8) and (10,6). line b is perpendicular to a. what is the slope of line b?
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.

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?
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
She uses 13 of her supply of sunflower seeds to make a salted snack mix and 29 of her supply to make an unsalted snack mix. If Cecile uses 10 pounds of sunflower seeds, how many pounds of seeds are in her supply?
Answer:
18 pounds
Step-by-step explanation:
Here is the full question :
Cecile packages snack mix at a health food store.
She uses 1/3 of her supply of sunflower seeds to make a salted snack mix and 2/9 of her supply to make an unsalted snack mix. If Cecile uses 10 pounds of sunflower seeds, how many pounds of seeds are in her supply?
Let x = Cecile's supply
1/3 of x = 1/3x
2/9 of x = 2/9x
1/3x + 2/9x = 10
adding the fraction together gives 5/9
5/9 x = 10
solve for x = 18 pounds
