Answer:
14. (0,1)
Step-by-step explanation:
To find the solution set, substitute and evaluate each point into the given equation. If it makes it true then it is part of the solution set.
14. y = 4x + 1
(2,-1)
-1 = 4*2 + 1
-1 = 9 FALSE
(1,5)
5 = 4*-1 + 1
5 = -3 FALSE
(9,2)
2 = 4*9+1
2 = 37 FALSE
(0,1)
1 = 4*0+1
1=1 TRUE
Ratio
if 13.3:9.5=2.52:1.8 then they ar similar
we do
13.3/9.5=2.52/1.8?
1.4/1=1.4/1
ratio is 1.4:1 or invert 1:1.4
answer is 2nd choice
yes; 1:1.4
Number of rooms left excluding a quarter of 140 is: 105 rooms.
<h3>What is a Quarter of a Number?</h3>
A quarter is one-fourth. A quarter of a number is therefore, one-fourth of that number or 1/4 part of the number.
Therefore, number of rooms cleaned = 1/4(140) = 35.
A quarter of the 140 rooms is: 35.
Number of rooms left for cleaning in the afternoon = 140 - 35
Number of rooms left for cleaning in the afternoon = 105 rooms.

Answer: Archimedes go to sleep at 8.32 metres away from the rock.
Step-by-step explanation:
Given that the rock beside which he slept was 5 meters tall
Height h = 5m
Angle Ø = 31 degree
To get distance x away from the rock, we will use trigonometry function. SohCahToa
TanØ = opposite/adjacent
Tan 31 = 5/x
x = 5/tan31
x = 8.32m
