Answer:
240, 1800, 2040
Step-by-step explanation:
First find the surface area of the shape - base = 3 x 15 x 2 + 40 x 15 + 40 x 3 x 2 = 930 m ^2
Now find the area of base = 40 x 15 = 600
Now, the cost of painting = 10 pounds for 25 m^2. SO here cost = 600 / 25 x 10 = 24 x 10 = 240 pounds.
Now cost of tiles = 600 x 3 = 1800
Total cost = 1800 +240 = 2040
Hi!
I think that there is a mistake in your question: only the first student says 5, not each student.
From the second student on, the student will say the previous number +4-1, that is the previous number +3.
So the second student will say 8, third 11, etc...
this will be repeated 9 times when Victor says his number (the first student doesn't have to change anything), so the number will increase 9 times: so it will increase 9*3=27
So Victor will say 32: 27 plus the original 5.
And all the numbers said will be:
5
8
11
14
17
20
23
26
29
32 - Victor
His hike changed 247 m in elevation.
Answer:
It will always be the case when A and B are opposites
Step-by-step explanation:
sin(x) = -sin(-x) so ...
sin(A -A) = (A -A) = sin(A) -sin(A) = 0
That is, the given expression is true when B=-A.
5 Points away could mean it is either (-2, -2) or (-2, -12)
