Answer:
(-4,0)
Step-by-step explanation:
We start at the origin (where the lines cross)
We will go left 4 units. That is the x coordinate (-4)
We go up 0. That is the y coordinate
(x,y)
C = (-4,0)
The expression we need to solve is:
To solve this problem, we need to not that we can simplify the fraction 2/10 by dividing both number by 2:
Answer:
262 square feet
Step-by-step explanation:
The lateral surface is the side surfaces, except top and bottom.
There are 3 lateral surfaces.
The 2 sides are triangles with length 20 and height 8.5
And
The back is a rectangle with length 12 and height 8.5
We sum up all the 3 surface areas, that will give us the answer.
Area of triangle is (0.5) * length * height
So,
Area of 1 triangle = 0.5 * 20 * 8.5 = 80
Area of 2 triangles = 80 * 2 = 160
Area of rectangle = length * height
so,
Area of back rectangle = 12 * 8.5 = 102
Total Lateral Surface Area = 160 + 102 = 262 square feet
Answer:
126 km/h
378 km
Step-by-step explanation:
To convert m/s into km/h, we multiply it by 3.6.
35 m/s x 3.6 = 126 km/h.
Distance travelled in 3 hours = 126 x 3 km = 378 km.
40 in2.
To find the area you multiply the width by length so you would have to find what multiplied by what would equal 100. This gives you the answer of 10. To find the perimeter you add up all the sides and because a square has 4 sides you would add 10+10+10+10 which equals 40. Hope this helped!
