Answer:
Option (2) [Graph on the top right]
Step-by-step explanation:
To find the temperature decrease by 0.5 degrees every hour we will find the slopes of the lines given in every option.
Option (1) [Top left graph]
Slope = 
= 
= -10
Option (2) [Top right]
Slope = 
= -0.5
Option (3) [Bottom left]
Slope = 
= -1
Option (4) [Bottom right]
Slope = 
= -12
Therefore, Graph given in option (2) will represent the decrease in temperature by 0.5 degrees per hour.
Answer:
15,17,19
Step-by-step explanation:
assume the first number is X which means the third number will be X+4 so X+ X+4=34
solve for X which will be 15
thus the numbers are 15,17 and 19
Answer:
19
Step-by-step explanation:
10 x 19 = 190
190 divided by 2 = 95
95 x 12 = 1140
Student 1 was correct. When compass is placed at M and width is adjusted to L, that distance between M and L corresponds to the angle ∠LQM. Therefore the distance between L and M should be equal to the distance between N and point T which is to be constructed. IF the distance LM = NT then the angles ∠LQM and ∠NPT are equal . these are corresponding angles which means that PT and QR are parallel.
PT straight segment is extended. Since opposite sides in a rhombus should be equal, the compass width is adjusted to QR and compass is placed on P to mark the distance of where point S will line on the extended PT line. This is so that PS = QR.
hence, a line PS is drawn that is parallel to QR and equal in length
