To make sure we don't have negatives under the square root, we specify that
(x is greater than or equal to 0). We'll use this fact later on
--------------------------------------------
Start with the given inequality
and square both sides to get
. Couple this with the fact that
means we have this compound inequality
What does this mean? It means that we can pick any value from 0 to 49 (including both endpoints) and it will be a solution to the inequality. This applies to the values
49, 48 and 44Answers: Choice C, Choice D, Choice E
Answer:
A
Step-by-step explanation:
Since DE is parallel to AB and intersects the other 2 sides, it divides those sides proportionally, that is
=
Note that AD = 33 - 22 = 11
Substitute values into the ratio
= = ( cross- multiply )
2x = 16 ( divide both sides by 2 )
x = 8
To find y use similar triangles
Δ ABC is similar to Δ DEC, thus ratios of corresponding sides are equal
= , substitute values
= = ( cross- multiply )
3y = 36 ( divide both sides by 3 )
y = 12
Thus y = 12, x = 8 → A
My math is 6%= 0.06*650=39*60 is $2,340 if i am correct please mark as brainliest thx:)
add them then divide by 3
16.00 + 40.00 + 130 = 186.00
186.00/3 = 62.00
the average is 62.00
Let's start by putting the information on the table into fraction form.
So:
O: 9/20
Y: 5/20
B: 6/20
We now know the probability of picking the different colour chips when the experiment is repeated 20 times but we want to know the probability if the experiment was repeated 80 times. So, we have to find out what number to multiply the probabilities by to get the answer over 80. So:
80/20 = 4
4x9 = 36
Thus the probability of picking an orange chip should be 36/80 and so she should expect to pick up 36 orange chips !
