Find the area of each shape by decomposing it into smaller shapes, and combining their area.
Answers
you can divide this picture into 2 pieces, 1 rectangle and 1 triangle.
To find the rectangle, since the opposite sides are equal to each other, the width=6.
the length is 8.
to find the area, use the formula
A = lw
A= 8 x 6
A = 48 units square
that's for rectangle.
for the triangle, use the formula
A = h x b / 2
height=10-6 = 4
base is 8 because the opposite sides are equal in rectangle.
Substitute height and base in the formula.
A= 4 x 8 / 2
A= 32/2
A=16 units square
That's the area of triangle.
Now, you can add the area of rectangle and triangle.
Total area = area of rectangle + area of triangle
A = 48 + 16
A = 64 units square
How do I find which is greater 0.49 or 0.5

a sum of RS 500 is in the form of denominators of RS5 & RS 10..if the total no. of notes is 90 ,find the no. of notes of each type................ do it by process will be mark as best
Answers
let rs.5 denominations be x , then rs 10 denominations will be 90-x
then total amount 5x + 10(90-x) which is rs.500
5x + 10(90-x) = 500
900 - 5x = 500 400 = 5x therefore x = 80 therefore no. of rs.5 is 80 no. of rs.10 is 90-x = 90-80 = 10

What is the volume of a cone that has a radius of 4 cm and a height of 9 cm?Use 3.14 to approximate pi and express your answer in hundredths.
cm3
Answers
volume of a cone= radius^2 (pi) height/3 4^2(pi)9/3 48(pi) 48(3.14)=150.72 answer= 150.72 cm^3
150.8 cm cubed because pi times radius squared times the hieght divided by 3 equals 150.79645
