Answer:
<h2>10.3seconds</h2>
Step-by-step explanation:
Step one:
given data
acceleration,a= 10ft/sec^2
final velocity v= 70mph
first, let is convert mph to ft/sec
1mph is 1.46667 ft/sec
70 mph is x
cross multiply we have
x= 102.7ft/s
Step two:
we are using the first equation of motion
v=u+at
initial velocity u= 0m/s
102.7=0+10*t
102.7=10t
divide both sides by 10
t=10.3seconds
You can do
3 * 2 and 11 * 2 which would be 6:22 and is still equal to the ratio 3:11. Your explanation can be the when divided by 2 or the number you multiplied by, you would get the original ratio
Examples:
6:22
9:33
12:44
Answer:
i dont know
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
what i did since we know a triangle is 180°, I added all the x's so all the x's added up to 12. i did 180÷12 because you want to find what just one x is
Answer:
(x-4)²
Step-by-step explanation:
(x-4)²
(x-4)(x-4)
x(x-4)-4(x-4)
x²-4x-4x+16
x²-8x+16
