John rides his motorcycle with a constant speed of 76 km/h. How far can he travel in 1 1/2 hours?
Answers
Answer: the answer would be 114 KM in 1 and a half hour
Step-by-step explanation: since there is no answer choice, this is only my assumption, and by assumtion i mean math calculation like 76 + 38 equals 114. 1/2 an hour john travels 38 KM's, so add it with how far john travels in 1 hour (78 KM's) and you get 114 KM's in 1 and a half hours.
if you rolled two dice what is the probability that you would roll a sum of 10
Answers
The probability of rolling a sum of 10 with two dice is 1/12.
What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.
Given that two dice are rolled and find the probability of a sum of 10.
The sample space of the event of rolling two dice is
S = {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6),
(2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6),
(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6),
(4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6),
(5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6),
(6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)}
The total possible outcomes is 36.
The favorable outcomes that is the outcomes where the sum is 10 is
(1, 4), (2, 3), (3, 2).
The number of favorable outcomes are 3.
To find the probability of rolling a sum of 10 with two dice, write the sample space and then determine the number of favorable outcomes that is the outcomes where the sum is 10 and the total number of possible outcomes.
The formula to find out the probability of any event is:
\(\text{P(event)} = \dfrac{(\text{number of favorable outcomes})}{\text{total number of possible outcomes}}\)
By using the data and formula, the probability of rolling a sum of 10 is,
\(\text{P(event)} = \dfrac{(\text{number of favorable outcomes})}{\text{total number of possible outcomes}}\)
\(\text{P(rolling a sum of 10)} = \dfrac{3}{36}\)
On dividing both numerator and denominator by 3 gives,
\(\text{P(rolling a sum of 10)} = \dfrac{1}{12}\)
Hence, the required probability of rolling a sum of 10 with two dice is 1/12.

The probability that you would roll a sum of 10 if you rolled two dice is 1/12.
We need to consider all the possible outcomes and count the favorable outcomes to determine the probability of rolling a sum of 10 when rolling two dice.
When rolling two dice, each die has six possible outcomes, ranging from 1 to 6. To find the total number of outcomes, we multiply the number of outcomes for each die: 6 * 6 = 36.
Next, we need to count the number of favorable outcomes, which are the combinations of two dice that result in a sum of 10. These combinations include:
1. Rolling a 4 on the first die and a 6 on the second die: (4, 6)
2. Rolling a 5 on the first die and a 5 on the second die: (5, 5)
3. Rolling a 6 on the first die and a 4 on the second die: (6, 4)
There are three favorable outcomes.
Therefore, the probability of rolling a sum of 10 when rolling two dice is:
Probability = (Number of favorable outcomes) / (Number of total outcomes) = 3/36 = 1/12.
Hence, the probability is 1/12.

Paul and Cindy own different pizza shops. Paul makes 12 pizzas the first day and 6 pizzas each day after that. Cindy makes 16 pizzas the first day and 4 pizzas each day after that. Who will have made more pizzas after 9 days? How many pizzas will that person have made?
A.
Paul. He has made 80 pizzas after 9 days.
B.
Cindy. She has made 132 pizzas after 9 days.
C.
Paul. He has made 60 pizzas after 9 days.
D.
Cindy. She has made 48 pizzas after 9 days.
Answers
Answer:
c
Step-by-step explanation:
Paul made 60 pizzas after 9 days because he made 12 pizzas in the first day so 8 days is left and if you multiply 6×8=48 and you add the 12 pizzas of the first day you get 60.
6×8+12=60
Two factory plants are making TV panels. Yesterday, Plant A produced 4 times as many panels as Plant B. Three percent of the panels from Plant A and 2% of the panels from Plant B were defective. How many panels did Plant B produce, if the two plants together produced 1260 defective panels?
Answers
Answer:
Step-by-step explanation:
x=# of panels plant B produced
3x=# of panels plant A produced
2%(x)+5%(3x)=1360
0.02(x)+0.05(3x)=1360
0.02x+0.15x=1360
0.17x=1360
17x=136,000
x=136,000/17
x=8,000 panels were produced by plant B

Answers
Answer:
Last option: {-5, -1, 2, 11}
Step-by-step explanation:
Required inequality is x > -6
That means every item in the set of values indicated should be > - 6
We should eliminate answers with - 6 since -6 is not greater than -6 it is ≥ -6
That leaves 2 and 4
When comparing negative numbers, a negative number which has absolute value greater than the absolute value of another number will always be less than the other number
For example, -11 has absolute value 11
- 6 has absolute value 6
11 > 6
So - 11 < -6
All the values in option 2 are therefore < - 6
Therefore last option is the correct one
-5 > -6, -1 > -6 and positive numbers are always greater than negative numbers
A jar contains 5 blue marbles, 8 red marbles, 4 white marbles, and 3 purple marbles. Suppose you pick a marble at random without looking. Find the probability of the event.
Answers
Answer: A 1/5
Step-by-step explanation:
Probability of getting blue marble, red marble, white marble, and purple marble are 1/4, 2/5, 1/5 and 3/20 respectively.
What is probability ?
Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.
Given that,
Number of blue marbles = 5,
Number of red marbles = 8,
Number of white marbles = 4,
And number of purple marbles = 3.
Total number of marbles = 5 + 8 + 4 + 3 = 20
Probability of getting blue marble = number of blue marbles/total number of marbles
=5/20=1/4
Apply same formula,
Probability of getting red marble= 8/20 = 2/5
Probability of getting white marble = 4/20 = 1/5
Probability of getting purple marble = 3/20
Answer:
A 1/5

3) 4(5 + x)(10 + x) = 600
(5 + x)(10 + x) = 150

Step 3: -110 = 22x
Step 4: -5 = x
