You have to get X all by itself so you divide 20 and 30 which gives you a fraction. X= 20/30
Then = 2/3
Answer:
5/14
Step-by-step explanation:
The total number of cards is 8
There are 5 blue cards
P(1st card is blue) = blue/total = 5/8
We take away a blue card
The total number of cards is 7
There are 4 blue cards
P(2nd card is blue) = blue/total = 4/7
The probability of blue blue is P(blue blue ) =
P(1st card is blue)*P(2nd card is blue) =
5/8* 4/7
20/56
We can divide the top and bottom by 4
5/14
Answer:

Step-by-step explanation:
because this eats the other organisims
Answer: Hello mate!
We know that you have a graph of y vs t, and we know that this is an "altitude" graph.
Then we can assume that the y represents the altitude, and t represents the time, and this graph shows the altitude of something as a function of the time.
the t-intercept means that the graph passes through the y-axis, this means that, in this point, y is equal to zero:
Then, at the t-intercept, we have y = 0, which means that at this time (where is the intersection) the altitude is equal to zero.
The y-intercept means that the graph passes through the y-axis, where t = 0
this is the initial value of the altitude, where t = 0 usually denotes the time where we start to measure.
Answer:
28 portraits
Step-by-step explanation:
Let's first figure out how many portraits Lamy can paint in 1 week, which is his <u>unit rate</u>. To calculate this, we just have to divide the number of portraits he paints by the amount of time it takes him to paint them.
In this case, the former quantity is 84 portraits, and the latter quantity is 6 weeks, so his unit rate is 
= 14 paintings per week.
Now, we know that in 1 week, Lamy can paint 14 portraits. Therefore, since this is a <u>directly proportional relationship</u>, all we have to do to find how many portraits he can paint is 2 weeks is double the unit rate. This is because in a directly proportional relationship, if you multiply one variable by a number, you have to multiply the other by the same number to maintain equality, and here we are multiplying weeks by 2 so we need to multiply paintings by 2 as well.
Thus, Lamy can paint 14 · 2 = 28 paintings in 2 weeks.
Hope this helps!
