A box of matching game pieces contains 8 red pieces, 5 green pieces, and 7 yellow pieces. You reach in and randomly take out one piece and then a second piece. Find the probability of drawing a green piece followed by a red piece.
Answer:
The correct answer is 2/19
Step-by-step explanation:
Step 1
We start by breaking up the process into 2 parts. The first part of the process is finding the probability of selecting a green piece out of 20 pieces. Since there are 5 green pieces, this probability is 5/20
Step 2
The second part of this process is that of selecting a red piece out of 19 pieces since the first piece was not replaced. If the first piece was green, taken without replacement, there are now 8 red pieces out of 19 pieces in total
Step 3
The next step is t find the probability using the multiplication rule. To find the probability of finding green piece followed by a red piece we just multiply the probabilities from step 1 and 2.
When = 3, what will the value for y be for the equation - 4x + 5y = 18?
If x equals 3 then y must equal 1.2
Answer: y=6
-4(3)+5y=18
-12+5y=18
add 12 to both sides
-12+5y+12=18+12
5y=18+12
5y=30
divide both sides by 5
5y÷5=30÷5
y=30÷5
y=6

Rachel has already written 10 pages, and she expects to write 1 page for every additional hour spent writing. How many hours will Rachel have to spend writing this week in order to have written a total of 27 pages?
Answer:
27?
Step-by-step explanation:
because 1 page per 1 hour leads up to 27 hours for 27 pages. Or if your not counting the 10 pages she has already written, she spent 17 hours.
What is the value of y in the picture
A. 83
We can see that the Y value is less than 90 degrees or right angle. So we can cross out answer options C and D.
And we should know that all of the triangles add up to 180 degrees.
So the math would do is:
46+51=97
180-97=83
So...
The Y value is 83.

How do I find the slope of the line from the graph?
Answer:
The slope is most easily defined as rise over run.
First, find a point you like because it is directly on the line and is where for example starting from the origin which you know should be always (0, 0).
Then find another point that is on the line and is perfectly aligned where on the graph is like (1, 2).
Then, as I said earlier, rise over run. So you climb up from for example the origin which is in the graph and climb up to the (1, 2) point. It should go up two units because it is increasing in intervals of 2 but has the notches in the half mark of 1.
So the rise is 2 because it climbed from 0 to 2.
The run is running from the 0 in the origin on the x-axis and running to the 1 because it is (1, 2) where it is in the form (x,y).
Since it is rise over run, the rise is 2 and the run is 1 so 2 over 1 is 2.
Hence the slope is 2.

Yosemite Falls is the highest waterfall in North America and the fifth highest in the world. When viewed from the valley, it appears to be a single waterfall. However, it actually has three parts. The upper fall has the longest drop of 1430 feet. The middle cascade is 675 feet long, and the lower fall drops another 320 feet. What is the total length that the water falls?
Answer:
The water falls a total length of 2,425 feet
Step-by-step explanation:
In order to calculate the total length of the waterfall, we will find the sum of the three parts of the waterfall.
Length of upper fall = 1430 feet
Length of middle cascade = 675 feet
Length of lowe fall = 320 feet
Total length of fall = (Length of upper fall) + (Length of middle cascade) + (Length of lowe fall)
= 1430 + 675 + 320 = 2,425 feet
Total length that the water falls = 2,425 feet

1.Two cyclists are 7 miles apart when they begin biking away from each other in opposite directions. The speed of the first cyclist is 12 miles per hour. The speed of the second cyclist is b miles per hour greater than the speed of the first cyclist.
How many miles does the first cyclist bike in 45 minutes?
Answer:
9 miles
Step-by-step explanation:
If 1 hour is 12 miles, then 30 mins is 6 miles, then 15 minutes is 3 miles.
30+15=45
6+3=9
The first cyclist bikes 9 miles in 45 minutes.
Since two cyclists are 7 miles apart when they begin biking away from each other in opposite directions, and the speed of the first cyclist is 12 miles per hour, to determine how many miles does the first cyclist bike in 45 minutes the following calculation must be done:
60 = 12 45 = X 45 x 12/60 = X 540/60 = X 9 = X
Therefore, the first cyclist bikes 9 miles in 45 minutes.

Jaxon was asked 40 questions on a test he answered 80% incorrectly how many did he get correct
Answer:
8 correct.
Step-by-step explanation:
80 / 100 = x / 40 (Since he got 80% INCORRECT you will subtract the value of x from 40)
100x = 80 x 40
x = 3200 / 100
x = 32
40 - 32 = 8

Answer: its either a or b
Error is the difference between the actual length of an object and its measured length.
The closest to the percent error for Diego's measurement is 4.3%
Step 1: Find the error
Error = Actual length - Measured length
= 23cm - 22cm
= 1 cm
Step 2: Find the percent error
Formula = Error/ Actual length × 100
= 1 /23 × 10
= 4.35%
Therefore, the closest to the percent error for Diego's measurement is 4.3%

2. Sarah has some blue marbles, twice as many red marbles as blue, and 8 yellow marbles. If she has a total of 32 marbles, how
many red marbles does she have?
A.8
B.12
C.16
D.24
Given:
Number of blue marbles, twice as many red marbles as blue, and 8 yellow marbles.
She has a total of 32 marbles.
To find:
The number of red marbles.
Solution:
Let number of blue marbles be x.
Then, number of red marbles = 2x
Number of yellow marbles = 8
Total number of marbles = 32
[tex]x+2x+8=32[/tex]
[tex]3x=32-8[/tex]
[tex]3x=24[/tex]
[tex]x=8[/tex]
Now,
Number of red marbles [tex]=2(8)=16[/tex]
Therefore, there are 16 red marbles.
