An athlete ran a sprint of 100 ft in 3.1 s. At what speed was the athlete running in miles per hour? Round to the nearest mile p
nordsb [41]

Answer:

22 miles per hour

Step-by-step explanation:

we know that

The speed is the ratio of distance by the time

Let

d -----> distance in feet

t ----> time in seconds

s ----> the speed in ft/sec

s=\frac{d}{t}

we have

d=100\ ft\\t=3.1\ sec

substitute

s=\frac{100}{3.1}

s=32.26\frac{ft}{sec}

Remember that

1\ mi=5,280\ ft

1\ h=3,600\ sec

Convert ft/sec to mi/h

s=32.26\frac{ft}{sec}=32.26\frac{(1/5,280)}{(1/3,600)}=32.26(\frac{3,600}{5,280})=22\ \frac{mi}{h}

Which of the following expressions has a value between 5 and 6.
Airida [17]
So listen to this logic
lets say you have 3 numbers, m,a,x where they are all positivie
m>a>x
therefor
m^2>a>2>x^2
if m and a and x are square roots, therefor we can reverse the square root
confusing sorry

square 5 and 6
5^2=25
6^2=36

the number betwe 25 and 36

that would be 32

answer is √32

goes like this
5^2<32<6^2
sqrt both sides
5<√32<6

answer is √32

a 240 centimeter board is to be cut into two pieces so that the longer piece is twice as long as the shorter piece. find the len
amid [387]
You need two pieces and 1 has to be 2x longer than the other 
set x as the smaller piece (easier to always go with the smaller value as x)
the other piece is 2x (double in size)
your equations would be 3x=240>>> x= 60

so smaller piece/ x= 60
bigger piece/ 2x= 120
