Answer:
Step-by-step explanation:
The given equation is
This is a quadratic equation in
To solve using the quadratic formula, we substitute
Answer:
u = -20
Step-by-step explanation:
-52 - 3u = 8
-3u = 8 + 52
-3u = 60
<u>u</u><u> </u><u>=</u><u> </u><u>-</u><u>2</u><u>0</u>
Answer:
0.889
Step-by-step explanation:
I think it is multiplied.
10 *9 = 90
which is the total number of ways you can draw 2 cards without replacement.
I think it is easier to figure out how many possibilities there are over 62 and go from there.
10*9
10*8
10*7
===========
9*8
9*7
So there are 5 combinations that are over 62. There are 5 more possibilities because you could draw them in the reverse order
9 * 10
8 * 10
7 * 10
8* 9
7 * 9
In all there are 10 ways of drawing numbers that are over 62
So what is the probability of drawing 2 cards above 62?
10/90 = 1/9 = 0.111
Therefore, there must be a probability of 1 - 0.111 for under 62 = 0.889
53.65 gallons → B
Since the tanks are equal in size then to find the volume of 1 tank
divide the total by 12
one tank = = 53.65
Answer:
15 units.
Step-by-step explanation:
The hypotenuse of the smaller triangle = sqrt (3^2 + 4^2)
= sqrt 25 = 5.
As the scale factor is 1:3 the hypotenuse of the larger triangle = 5 * 3
= 15.
