Evaluate and simplify the following complex fraction.:6/7 ÷ 3/11​

Mathematics
1 answer:
inna [77]2 years ago
3 0

Answer:

3  7/50

Step-by-step explanation:

so you need them to become common denominators

a common multiple they both have would be is 77

6/7 becomes 66/77 and 3/11 becomes 21/77

now we divide

keep the 66/77 as is and flip 21/77 (keep, change, flip)

so now our equation looks like this: 66/77 x 77/21

and your answer is 3.14

but as a fraction it is 157/50 and to simplified it would be 3 7/50 (mixed fraction)

Is the expression 2f + 4f + 2 – 3 equivalent to 6f – 1? 6f – 1 evaluated at f = 9 is 53. 2f + 4f + 2 – 3 evaluated at f = 9 is a
morpeh [17]
We have that

the expression 2f + 4f + 2 – 3-------> we can group it   (2f+4f)+(2-3)
(2f+4f)+(2-3)=(6f-1)
therefore
the expression [2f + 4f + 2 – 3] is equivalent to [6f-1]

if the expression [6f-1] for f=3 is 17
then
the expression [2f + 4f + 2 – 3] for f=3 is also 17

<span>let's check it
</span>[2*3 + 4*3 + 2 – 3]--------> [6+12+2-3]=[20-3]=17------> is ok

Nuetrik [128]

Answer: v= 56 ft per second


Step-by-step explanation:

Given: A quarterback throws a football to a teammate.

Projectile motion formula is given by :-

h(t)=-16t^2+vt+h_0, where h_0=6.5

Now, to find  v at h=5 and t=3.5, substitute these values in the above equations, we get

5=-16(3.5)^2+v(3.5)+6.5\\\Rightarrow5=-16(12.25)+3.5v+6.5\\\Rightarrow5=-196+6.5+3.5v\\\Rightarrow\ 5=-189.5+3.5v\\\Rightarrow\ 3.5v=5+189.5\\\Rightarrow\ 3.5v=194.5\\\Rightarrow\ v=55.57142\approx56
