There is a bag filled with 6 blue and 5 red marbles. A marble is taken at random from the bag, the colour is noted and then it is replaced. Another marble is taken at random. What is the probability of getting exactly 1 red?
5/11
Was there a picture or something? if so can you show it so I can help
78 x 100 = 7800
<span>How many times does 190 go into 780? </span>
<span>≈ 4....190 x 4 = 760 </span>
<span>780 - 760 = 20...bring down the extra 0 to make it 200. </span>
<span>How many times does 190 go into 200? </span>
<span>≈ 1...subtract 190 from 200 to get a remainder of 10 </span>
<span>190 ÷ 7800 ≈ 41</span>
Hope I Helped You!!! :-)
Have A Good Day!!!
Answer:
7
Step-by-step explanation:
Q R
T S
I put the letters here in order, a clockwise order starting at Q.
If you look at our diagram you will see that RT and QS are actually the diagonals of this rectangle.
The diagonals of a rectangle are congruent.
We have the measurement of RT = the measurement of QS.
That is we have this equation: 4x-16=x+5.
4x-16=x+5
Subtract x on both sides:
3x-16= 5
Add 16 on both sides.
3x = 21
Divide both sides by 3.
x = 7
Answer:
4 stacks of packages
4 * 4 = 16 pieces of pancake
Step-by-step explanation:
Maximum amount to spend ≤ $30
Milk chocolate = $3.25
Pancakes per stack = 5.50 (sold in stacks of 4)
Let number of stacks = s
In equality terms :
3.25 + 5.50s ≤ 30
5.50s ≤ 30 - 3.25
5.50s ≤ 26.75
s ≤ 26.75 / 5.50
s ≤ 4.86
Hence, 4 stacks of pancakes can be purchased
