Answer:
1. 50 m
2. 80 cm
Step-by-step explanation:
1. There are 2 triangles, subtract the area of 1 of them from the other.
The triangle that needs to be subtracted: b = 20 m, h = 10 m
A = 1/2b * h = 1/2(20) * 10 = 10*10 = 100 m
The big triangle, the one that needs to be subtracted plus the one you need to find the area of: b = 20 cm, h = 15 cm, 1/2(20) * 15 = 10 * 15 = 150
150 - 100 = 50 c
2. Divide it into 3 parts:
1- 3*4 = 12
2. 7*(4 + 4) = 7*8 = 56
3. [(4 + 4) * (13 - 7 - 3)]/2 = (8*3)/2 = 24/2 = 12
12 + 56 + 12 = 80 cm
She needs 0.1 because 4x4 is 16. :)
900-2*x>500
2x<900-500
2x<400
x<200
Answer:Beth can ride the bus less 200 times
there isnt much here but answer is width=X and length=Y and X times Y
for example, if you had a room that was 3 feet long and 10 feet wide, it would be 30 square feet.
A decagon has 10 sides therefore it has 10 interior angles
