Answer:
a) 62
b) 31/45
Step-by-step explanation:
a) The table tells you there are 42 males, and 20 more females that study biology.
42 +20 = 62 . . . are male or study biology or both
__
b) Of the total of 90 people, 62 are male or study biology (or both). The probability that any person is in that category is ...
62/90 = 31/45 = P(male or biology)
$60. You change 25% to the decimal of .25 and multiply it by $240 to see what 25% of $240 is.
Answer:
x=1
Step-by-step explanation:
Step 1: Subtract 3x from both sides.
x+4−3x=3x+2−3x
−2x+4=2
Step 2: Subtract 4 from both sides.
−2x+4−4=2−4
−2x=−2
Step 3: Divide both sides by -2.
-2x/-2 = -2/-2
Hello,
A=πr²
dA/dt=2πr*dr/dt
if dr/dt is constant, dA/dt is linear.
