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
Answer:
16 3/10
Step-by-step explanation:
Think about what fraction become .3 when put into a calculator
that's a 3 in the tenths place in the decimal system so the fraction would be 3/10. Then finally add on the 16
*an aside if this is wrong it it is possible that they have rounded 1/3 to one decimal place. (1/3 is usually .33333 repeating)

Step-by-step explanation:
The triangle with side lengths 10", 24", and 26" is a right angle triangle
<u>Explanation:</u>
Given:
Sides of a triangle:
a = 10 in
b = 24 in
c = 26 in
To prove: right angle triangle
Using pythagoras theorm:
(c)² = (a)² + (b)²
(26)² = (10)² + (24)²
676 = 100 + 576
676 = 676
Right hand side is equal to left hand side.
Thus, the triangle with side lengths 10", 24", and 26" is a right angle triangle
