Answer: 7th total= 46
more= 28
less=18
8th total= 27
more=15
less=12
both 7th and 8th total= 73
more=43
less=30
Step-by-step explanation:
7th total: it says that 46 7th graders were surveyed so 46 7th graders were surveyed.
7th more: it said that 28 7th graders spent more then a hour so 28 7th graders spent more then an hour on the survey.
7th less: it said the there were 16 7th graders surveyed and 28 7th graders that spent more than an hour on the survey so 46-28=18 so 18 7th graders spent less than an hour on the survey.
8th total: it said 27 8th graders were surveyed so 27 8th graders were surveyed.
8th more: it said 43 students were surveyed more than an hour and that 28 7th graders were surveyed over an hour so you have to subtract 43 by 28, so 43-28=15 so 15 8th graders were surveyed over an hour.
8th less: it said 27 8th graders were surveyed and we found out that 15 8th graders spent over an hour so you have to subtract 27 by 15 so 27-15 is 12 so 12 8th graders spent less than an hour on the survey.
7th and 8th total: it said 46 7th graders were surveyed and that 27 8th graders were surveyed so you have to add 46 and 27, so 46+27=73 so 73 students were surveyed.
7th and 8th more: it said that 43 students were surveyed over an hour so 43 students were surveyed over an hour.
7th and 8th less: we found out that 18 7th graders were surveyed under an hour and 12 8th graders were surveyed under an hour so we have to add 18 and 12, so 12+18=30 so 30 students were surveyed under an hour.

Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (negative 4, 1), (negative 4, 4), (2, 1). What are the coordinates of point S'?
Answers
Answer:
D. (2, -1)
Step-by-step explanation:
I took the test and got it right.
Triangle QRS is rotated 180° about the origin. On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1). So, the coordinates of point S will be (2, -1).
How does rotation by 90 degrees changes coordinates of a point if rotation is with respect to origin?Let the point be having coordinates (x,y).
If the point is in first quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
If the point is in the second quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
Triangle QRS is rotated 180° about the origin.
On a coordinate plane, triangle Q R S has points (-4, 1), (-4, 4), (2, 1).
So, the coordinates of point S will be (2, -1).

m = 1
Answer:
The answer is 1
Step-by-step explanation:
to calculate the slope m use the
gradient formula
m = y2 - y1/x2 - x1
let (x1, y1) = (4, 9) and (x2, y2) = (1, 6)
⇒ m = 6 - 9/1 - 4 = -3/-3 = 1.

This graph shows the distance vs. time relationship for the Lane 1 and Lane 2 turtles. Here are their equations:
Lane 1: d= 6+ 1t
Lane 2: d = 3t
Select all of the true statements.
(Select all that apply.)
1. The Lane 2 turtle is faster than the Lane 1 turtle.
2. At 3 seconds, the turtle in Lane 2 is 12 feet from the start.
3. At 12 seconds, the turtle in Lane 1 is 6 feet from the start.
4. The Lane 1 turtle has a head start.
Answers
Answer:
True statements are:
(i) The lane 2 turtle is faster than the lane 1 turtle.
(iv) The lane 1 turtle has a head start.
Step-by-step explanation:
Now we proceed to check the value of truth for each choice:
(i) The lane 2 turtle is faster than the lane 1 turtle.
Speed of the turtle is the slope of the linear function, the greater the slope, the faster the turtle. Hence, the lane 2 turtle is faster than the lane 1 turtle. (Answer: TRUE)
(ii) At 3 seconds, the turtle in Lane 2 is 12 feet from start.
Let the position of the turtle in Lane 2 be represented by [tex]d = 3\cdot t[/tex]. For [tex]t = 3\,s[/tex], then [tex]d = 3\cdot (3) = 9[/tex]. Hence, the turtle in Lane 2 is just 9 feet from the start. (Answer: FALSE)
(iii) At 12 seconds, the turtle in Lane 1 is 6 feet from the start.
Let the position of the turtle in Lane 1 be represented by [tex]d = 6 + t[/tex]. For [tex]t = 12\,s[/tex], then [tex]d = 6+12 = 18[/tex]. Hence, the turtle is 12 feet from the start. (Answer: FALSE)
(iv) The lane 1 turtle has a head start.
According to graph, Lane 1 turtle starts at a position of 6 feet, whereas Lane 2 turtle start at a position of 0 feet. Hence, Lane 1 turtle has a head start. (Answer: TRUE)

Lucy, Mary and Nora's father leaves them an inheritance in the
ratio 5: 3:2. Mary gets £4500, How much was there in total?
Answers
Answer:
£15000
Step-by-step explanation:
Lucy, Mary and Nora's father leaves them an inheritance in the
ratio 5: 3:2. Mary gets £4500, How much was there in total?
Giving the ratio of inheritance 5:3:2
5+3+2 = 10
Mary's ratio = 3
Marys share = £4500
Total share x can be gotten as thus
3/10 × x = 4500
3x/10 = 4500
3x = 45000
x = 45000/3
x = 15000
Hence £15000 was there in total
