All the numbers that you multiply to get 60
Area of the trapezium = 1/2 (40 + 160) x 70
Area of the trapezium = 7000 ft²
One bag of fertilizer = 4000 ft²
Number of bags of fertilizer needed = 7000 ÷ 4000 = 1.75 bags.
Since only full bags of fertilizer can be bought, 2 bags of fertilizer are needed.

Answer:
C. and E.
Step-by-step explanation:
Complimentary angles are two angles that both measures create the same degree as a right angle, or 90 degrees
Looking at the graph, we see 1 right angle, which is 9. Therefore we can cross out any answer that includes <9 in it.
Let's look at 7, this is an obtuse angle, WAY more than 90 degrees, therefore we can cross out any answer that includes <7 in it.
Meaning we only have three exceptable degrees, <6, <5, and <8.
There are only 2 answers that follow these rules. C and E

Your answer is only by color! Hope this helped!!
Let n = 1
then f(1) = 1^1 - 1 + 2 = 2 so it is true for n = 1
for the next number after n ( n+1) we have f(n+1) =
(n+1)^2 - (n+1) + 2
= n^2 + 2n + 1 - n - 1 + 2
= n^2 + n + 2
= n(n+1) + 2
Now n(n+1) must be divisible by 2 because either n is odd and n+1 is even OR n is even and n+1 is odd and odd & even always = an even number.
So the function is divisible by 2 for n+1 We have shown that its true for n = 1 Therefore it must be true for n = 1,2,3,4 ...
True for all positive integers
