Answer:

1. 1/36

2. 9/64

Step-by-step explanation:

First Question:

1. First thing I look for is how many spots are there and how many of them are for each color: both green and orange have 1 spot each out of six spots.

2. The chances of landing on each one is 1/6.

3. Now that they have to land back to back, I multiply the fractions by using the denominator which is 1 in 36 or 1/36.

Second Question:

1. Once again I see there are eight spots and blue has 3 of those.

2. I multiply the chance of it landing on blue on the first time, 3/8, by itself for the second time, 3/8.

3. You multiply the fractions and you get 9 in 64 or 9/64.

1. 1/6 for both

2. 3/8

Find an equation of the line that is perpendicular to the graph of 2x+5y=5 and contains the point of intersection of the graphs of y=x+4 and y–2x=5.

Answers

Answer: 5(x+1) -2(y-3) = 0

Step-by-step explanation: For a given line ax+by=c and point (h, k), a perpendicular line through the point can be written as ...

b(x-h) -a(y-k) = 0

A graphing calculator shows the point of intersection of the graphs of the two lines to be (x, y) = (-1, 3), so the line perpendicular to 2x+5y=5 through that point can be written ...

5(x+1) -2(y-3) = 0

What is the greatest common factor of 16 and 80? *
What is the greatest common factor of 16 and 80? *

Answers

Answer:

Step-by-step explanation:

-The greatest common factor of 16 and 80 is 16, it is the greatest number that divides evenly into it.

-The factors of 16 are 1,2,4,8,16;

-The factors of 80 are 1,2,4,5,8,10,16,20,40,80

The greatest common factor of 16 and 80 is 16.

To find the greatest common factor (GCF) of 16 and 80, we can list the factors of each number and identify the largest factor they have in common.

The factors of 16 are 1, 2, 4, 8, 16.

The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.

Looking at the lists of factors, we can see that the largest factor they have in common is 16. Therefore, the GCF of 16 and 80 is 16.

The GCF represents the largest number that can evenly divide both 16 and 80 without leaving a remainder. In this case, 16 is the greatest number that can divide both 16 and 80, as it is a factor of both numbers.

I can't really explain this in full detail since its pretty simple but all we would have to do is take 100 (the full precentage) and subtract 47 from it because we know that this is the precentage of girls in the school, and our answer would be 53%.

lacy went to the fair. She paid $5 for the entrance fee. Each ride ticket cost $0.25. Lacy spent $12.50 at the fair. Which equation can be used to find how many ride tickets Lacey bought?

$0.25r + $5 = $12.50
$0.25r + $5r = $12.50
5r + $0.25 = $12.50
$0.25r - $5 = $12.50

Answers

Answer:

$0.25r + $5 = $12.50

Step-by-step explanation:

r represents the amount of rides Lacy went on during the day. If you do the problem in the correct order, you will get the answer

Step 1)

Subtract 5 from both sides

$0.25r + 5 (-5) = 12.50 (-5)

Step 2)

Divide by 0.25

0.25r (Divided by 0.25) = 7.50 (Divided by 0.25)

Step 3)

Answer

r = 30 rides

$0.25r+$5=12.50 this is because you will have to subtract 5from both sides and then divide the sum( which is $7.50) by $0.25. So lacy purchased 30 tickets

It advanced from behind the mountains of Jura, and the thunder burst at once with frightful loudness from various quarters of the heavens. I remained, while the storm lasted, watching its progress with curiosity and delight. As I stood at the door, on a sudden I beheld a stream of fire issue from an old and beautiful oak which stood about twenty yards from our house; and so soon as the dazzling light vanished, the oak had disappeared, and nothing remained but a blasted stump.
