We know that one wall side is 5m.
To find the area of one wall, we do 5²=25m²
We know there is 4 walls. So we have to find total area of all four walls.
Which is 25×4=100m²
To find the total cost of white washing the room, we have to do:
100(total area)×23(cost per m²)=$2300
So the total cost of the area is $2300
Best not to use "x" to denote multiplication. "x" is usually a variable name in algebra.
3 times 3/5 comes out to 9/5, which is equivalent to 1 4/5.
You'd need to draw not one but two circles and divide each circle into 5 equal "slices." Then you'd shade one circle completely and shade 4 of the 5 slices of the other circle. 9 fifths (9 slices) would be shaded in all.
Answer:
h(4) = 1/2 (4) - 8 = 2 - 8 = -6
Step-by-step explanation:
Answer: 55°
Step by step:
80 + x = 180
x = 100
Because the bottom of the figure is a line which equals 180°, so you would subtract 80 from 180 to get the angle on the other side of the line dividing the triangles.
Then, you would use the triangle sum theory which states that the angles of a triangle equals to 180.
100 + 25 + x = 180
125 + x = 180
x = 55°
So angle CBD = 55°
