. Solve: 5x < 9x-1 / 2
<span>-4x < - 1/2 , now divide by -4 and switch signs </span>
<span>x > 1/8 </span>
<span>2. There is a 20% chance that it will snow on Monday and a 40% chance on Tuesday. What is the probability that it will NOT snow on both Monday and Tuesday? </span>
<span>P( NOT snow on both Monday and Tuesday) = (1-.2)(1-.4) = 12/25 </span>
<span>c. 12/25 </span>
<span>3. The total cost of renting a sailboat is $120 plus $60 a day. How many days was a sailboat rented if the total cost was $360? Solve. </span>
<span>120 + 60d = 360 </span>
<span>60d = 360 - 120 = 240 </span>
<span>d = 4 </span>
<span>4. Two cards are chosen at random without replacement from a deck of 52 cards containing 4 kings. Which expression could be used to find the probability of choosing two kings? </span>
<span>b. 4/52 x 3/51 </span>
<span>There are 4 x 3 ways to pick 2 kings </span>
<span>There are 52 x 51 ways to pick any two cards</span>
In this question, we can determine Maggie car initial speed (15m/s), final speed(0m/s) and the time her car moves (2.5s). Then to calculate the distance she travels, we need to multiply the average speed with time. The equation would be:
Distance traveled= (initial speed+final speed)/2 x time
Distance traveled= (0m/s + 15m/s)/2 x 2.5 second= 7.5m/s x 2.5s= 18.75m
Answer:
The right answer is amount of deposit, i just took the quiz
Step-by-step explanation:
1 dozen = 12
12 x 2 = 24
8/3 = x/24
3x=192
x=64
two dozen socks would cost $64
Answer:
10 sqrt(3)/3 =x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp side /adj side
tan 30 = x/10
10 tan 30 =x
10 ( sqrt(3)/3) = x
10 sqrt(3)/3 =x
