Write an expression that represents the difference of (4x + 2/3y) and (4/12y - 8.7x)
Help
Answers
Explanation:
(4x + 2/3y) - (4/12y - 8.7x) = 12.7x+1/3y
Convert 12.7x in the difference to a fraction, which is 127/10x.
Factor out 1/30 from 127/10x + 1/3y
Solution: 1/30x (381x+10y)
12.7x+1/3y
Maria has the following scores on exams in her social studies class: 86, 75, 97, 58, 94, and 58.
A. Find the mean, median, and mode of the scores.
B. Should Maria’s social studies teacher use the mean, median, or mode of the exam scores to convince Maria that she needs to study more regularly for her exams?
Answers
Answer:
Below in bold.
Step-by-step explanation:
Arrange the scores in ascending order:
58 58 75 86 94 97
A. The mean = (58+58 +75+ 86+ 94+ 97)/6
= 468/6
= 78.
The median = (75+ 86)/2 = 80.5.
The mode = 58.
B. She should use the mode as it is the lowest score.
Explanation: the mean is the average number in a data set, meaning you have to add all of the numbers and divide by the number of values (86 + 75 + 97 + 58 + 94 + 58) / 6
Median: 80.5
Explanation: The median is the value that separates the higher half from the lower half in a data set. in this case, you have to order the numbers least to greatest and since there is an even amount of numbers, you take the two middle ones and find the average of the two. (75 + 86) / 2
Mode: 58
Explanation: the mode is the value that appears most frequently in a data set, in this case it is 58
Part B: Maria’s social studies teacher should use the mode of the exam scores to convince Maria that she needs to study my regularly for her exams because it is the lowest score

88cm2
Step-by-step explanation:
You need to first find the area of all sides except the bottom, as you can see the bottom is a rectangle which means the triangles across from each other will have the same measurements.
To find the area of a triangle the formula is 1/2ab
1/2*8*6= 24
1/2*8*5=20
20*2+24*2=88
Therefore the answer is 88 cm2

There are 364 people that have to go from the airport to the hotel. One van can transport 12 people. How many vans are needed?
A. 4
B. 30
C. 31
D. 32
Answers
Answer:
30
Step-by-step explanation:
all you need to do is divide please let me know if the answer is incorrect
Answer:
Technically speaking: 31. (Or C.)
Step-by-step explanation:
We can solve this quite simply by dividing 364(amount of people) by 12(amount of people per van).
Which would look like this: 364/12=30.3333
The reason being for it being 31 and not 30 is because you would need one extra van to take the remaining 4 people that was not picked up by the 30th van, otherwise only 360 people would've been picked up.
