This problem involves finding arc lengths. The formula for arc length
is s = r*theta, where r is the radius and theta the central angle.
In 15 minutes, the minute hand sweeps out 1/4 of a circle, or pi/2 radians. This is the central angle. The arc length (how far the minute hand moves in 15 min) is then
s = (6 inches)(pi/2 rad) = 3pi inches, or about 9.42 inches.
25 minutes is equivalent to a central angle of (25/60)pi rad, or 1.31 radians. What is the associated arc length? Calculate this in the same way as I did for a central angle of pi/2.
1) JPR, JRP, PJR, PRJ, RJP, RPJ
2) To start with there are 4 green marbles and a total of 6 marbles.
First drawing: p(green) = 4/6 = 2/3
He replaces the first marble, so for the second drawing he has again 4 green marbles out of a total of 6 marbles.
p(green) = 4/6 = 2/3
The combined probability is the product of the 2 probabilities.
p(green followed by green) = p(green) * p(green) = 2/3 * 2/3 = 4/9
3)
Total number of combinations of 3 different shirts and 2 pairs of pants is 3 * 2 - 6. You are interested in a single combination out of a possible 6.
p(white shirt & tan pants) = 1/6
Answer:
0,4 1,2 2,1 3.5 4.25
Step-by-step explanation:
because i know
57 - 4t > = 13.....subtract 57 from both sides
-4t > = 13 - 57
-4t > = - 44 ...divide both sides by -4, and change the inequality sign
t < = -44 / -4
t < = 11
u solve inequalities much like u do equations except for one very important rule. In an inequality, if u divide/multiply by a negative number, u have to change the inequality sign.
Answer:
y = 2x + 2

just trust me i took test and it had this question on it lol
