Explanation- just did it :)
Square units are the units of measuring area. Therefore, this question asks for the area of the room.
The room has the shape of a rectangle with:
length = 13 units and width = 9 units
The are of the rectangle can be calculated using the following rule:
area of rectangle = length * width
area of the room = 13 * 9 = 117 square units
Do 3.14 times 4 because if one similar charm has a 1cm diameter and a circumference of 3.14 you could just multiply it
Y = mx + n
m = Slope
To two lines be perpendicular to each other the slopes need to meet the condition: ma x mb = -1
y = 2x + 5
ma = 2
D: y = -1/2x + 5
mb = -1/2
ma x mb = -1
2 x -1/2 = -1
2/1 x -1/2 = -1
-2/2 = -1
-1 = -1
It's true.
Answer: D.
Step-by-step explanation:
i think you missed a decimal place for 8.5°
when temperatures drop it means minus
so
-7.5-5-8.5= -21°
