AC/AE = AB/AD
AC/(AC+15) = 8/18
18AC = 8(AC+15)
18AC = 8AC + 120
18AC - 8AC = 120
10AC = 120
AC = 120/10
AC = 12
Answer:
small=15 large=40
Step-by-step explanation:
x=large box
y=small box
55 = x + y
50x + 55y = 2825
50x + 55( 55 - x) = 2825
50x + 3025 - 55x = 2825
0 = 55x - 50 x + 2825 - 3025
0 = 5x - 200
200 = 5x
x=40
y = 15
Answer:
The car's acceleration was 3.73 metre per second square = 3.73m/s²
Step-by-step explanation:
The car accelerated from rest.
initial velocity (u) = 0m/s
final velocity (v) = 25miles/hr = 11.2m/s
time (t) = 3s
a = ?
v = u+at
a = (v-u)/t
a = (11.2 - 0) / 3
a = 11.2/3
a = 3.73
a = 3.73m/s²
a
Answer:
Just about 3.6
Step-by-step explanation:
a² + b² = c²
√(a² + b²) = c
√(2² + 3²) = c
√(4 + 9) = c
√(13) = c
3.605551275 = c
c ≈ 3.6
