5 1/3 + (-4 1/6)+ (-2 1/2)
nlexa [21]

Answer:

-\frac{4}{3}

Step-by-step explanation:

We are given that

5\frac{1}{3}+(-4\frac{1}{6})+(-2\frac{1}{2})

We have to find the value of given expression

\frac{5(3)+1}{3}-(\frac{4(6)+1}{6})-(\frac{2(2)+1}{2})

=\frac{15+1}{3}-\frac{24+1}{6}-\frac{4+1}{2}

=\frac{16}{3}-\frac{25}{6}-\frac{5}{2}

LCM(2,3,6)=6

=\frac{32-25-15}{6}

=\frac{32-40}{6}

=\frac{-8}{6}

=-\frac{4}{3}

yarga [219]

Answer:

area of a cricle is

πr^2

take π to be 22÷7

A= πr^2

A=22÷7*15*15

A=22÷7*225

7 divides 225

22*34.142

A= 751.124

angelo rode his bike around a bike trail that was 1/4 of a mile long.he rode his bike around thetrail 8 times.Angelo says he rod
forsale [732]
Hi there!

From this problem we can pull out some key information and remove any excess.

- The trail is 1/4 of a mile long.
- Angelo rode around the trail 8 times.
- Angelo claims he rode 8/4 miles.
- Teresa claims he rode 2 miles.

From that we know that if Angelo rode around the trail 8 times and the trail is 1/4 a mile, he in total rode 8/4 of a mile.

However, Teresa claims he rode 2 miles!

And the answer is... they're both correct!

Angelo did indeed ride 8/4 miles however that is equivalent to 2 miles so they are both in the right.

marusya05 [52]

Answer:

17 1/4mph

Step-by-step explanation:

As you can see, Sarah rides her bike 5 3/4 in 1/3 hours. All you need to do is multiply 5 and 3/4 by 3 since it's thirds. 5x3=15. 3/4x3=9/4. 9/4= 2 1/4. 15+2 1/4= 17 1/4mph.
