Answer:
-2
Step-by-step explanation:
4x:3=6:5.
4x/3=6/5
4x × 5=6×3
20 X=18
X=18-20
X=-2
Okay so three quarters of an hour is 45 minutes.
6 hours = 360 minutes.
360/45 = 8.
So the scale factor is 8.
Just do 24 x 8 and you get the answer (192 carpet tiles)
I think this is right ??
The probability of choosing two yellow marbles = 5/26
Step-by-step explanation:
Step 1 :
Given
Total number of marbles in the bag = 13 marbles
Number of yellow marbles = 6.
We choose 2 marbles from the bag without replacing and need to determine the probability that both are yellow.
Step 2 :
Probability of finding yellow marble in the first try = Number of yellow marbles / Total number of marbles = ![\frac{6}{13}](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B13%7D)
Once the yellow marble is selected we have 5 yellow marbles among 12 remaining marbles in the bag.
Probability of finding yellow marble in the second try = Number of yellow marbles / Total number of marbles = ![\frac{5}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B12%7D)
Step 3:
P(yellow in first 2 tries) = P(yellow in first try) * P(yellow in second try)
P(yellow in first 2 tries) =
= ![\frac{5}{26}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B26%7D)
Step 4:
Answer:
The probability of choosing two yellow marbles = 5/26
We are given the expression S = 2πr^2 + 2πrh and is asked to solve for h. This is the formula of the surface area of a cylinder. In this case,
S - 2πr^2 = 2πr h dividing the whole equation by 2πr, thenh = (S - 2πr^2) / 2πrh = S/2πr - r
Answer:
The x value
Step-by-step explanation:
Basically, the question is asking you to find the straight line distance from the y axis to a given point. The y-axis on a coordinate plane is the axis that goes up and down, and the x axis is the one that goes left and right. In a coordinate pair (x,y), x is how far left or right the point is and y is how far up or down it is. so the point (3,9) is three to the right and three up. (See screenshot)
So, the distance that (3,9) would be from the y-axis would be how far right it is, or x, which is 3!
