Answer:
20cm
Step-by-step explanation:
for the triangle:
Perimeter = 30cm
a + a + a = 30
3a = 30
hence a = 10cm
For the rectangle:
a + a + b + b = 30
but a = 10cm
10 + 10 + b + b = 30
20 + 2b = 30
2b = 10
hence b = 5cm
Perimeter of square = b + b + b + b
= 5 + 5 + 5 + 5 = 20cm
y = mx + b
m = Slope
b = y-intercept
y = 8x - 2
m = 8
b = -2
y = 1/4x + 6
m = 1/4
b = 6
São eles: (3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17), (9, 40, 41), (11, 60, 61), (12, 35, 37), (13, 84, 85), (16, 63, 65), (20, 21, 29)
64
4^3, means 4*4*4, and it is very simple to calculate when you break it down to 4*4= 16 and then 16*4=64. So your final answer is 64.
You are looking for car b speed.
Car A traveled the distance in 2 h, and Car B traveled the distance in 1.5 h. Car B traveled 15 mph faster than Car A.
Formula r×t=d
2(s-15) = 1.5s
2s - 30 = 1.5s
2s - 1.5s = 30
0.5s = 30
S= 30/0.5
s peed of car b = 60 mph
