Step-by-step explanation:
Let a = the number of apples
And b = the number of bananas. Then,

Check:

OK.
Answer:

Step-by-step explanation:
AD = BD (CD bisects AB means that it divides the line into two equal parts)
So,
AD = BD = AB/2
So,
AD = 3/2
AD = 1.5
<u><em>Now, Finding AC using Pythagorean Theorem:</em></u>

Where c is hypotenuse (AC), a is base (AD) and b is perpendicular (CD)



Taking sqrt on both sides

Answer:
50
Step-by-step explanation:
Steven = 13 marbles
Julio = 13 marbles
Megan has twice the number of marbles as Steven and Julio combined
Megan = 2 (13 + 13) = 2(26) = 52 marbles
Among the options (26, 13, 50, 169, 338), the only reasonable estimate is 50
Answer:

Step-by-step explanation:
Given that from a well shuffled set of playing cards (52 in number) a card is drawn and without replacing it, next card is drawn.
A - the first card is 4
B - second card is ace
We have to find probability for

P(A) = no of 4s in the deck/total cards = 
After this first drawn if 4 is drawn, we have remaining 51 cards with 4 aces in it
P(B) = no of Aces in 51 cards/51 = 
Hence

(Here we see that A and B are independent once we adjust the number of cards. Also for both we multiply the probabilities)
