Answer:

radius = 7.0

Step-by-step explanation:

length of arc* 360/ 285 = circumference

-> 34.8 *360/285 = 43.957 cm

circumference = 2*pi*radius

-> 43.957 = 2* 3.14 * radius

->radius = 6.99996 = 7.0 cm

At a fruit stand, for every 5 apples sold there are 4 oranges sold. What is the ratio of oranges sold to apples sold?
Mashcka [7]
The ratio of oranges to apples would be 4 to 5, because every 5 apples sold, 4 oranges are sold, and we must put it oranges to apples.
Hope this helps!

I really need help on this question! Thank you!
KIM [24]

Answer:

A

Step-by-step explanation:

We know the following:

OE=5\\\\FG=4\\\\EF=8\\\\

so the segment EF is equal to

EF=EG+GO+OF\\\\

and here we can do a trick :)

EF=(EG+GO)+GO+(OF+OG)-2GO\\\\

you see it's the same

EF=EO-GO+FG\\\\

now we plug the values given

8=5-GO+4\\\\8=9-GO\\\\GO=9-8\\\\GO=1

so it's option A

What is the primary goal and secondary goal of the Fried Liver Opening in chess? <br />
polet [3.4K]

Play usually continues 7.Qf3+ Ke6 8.Nc3 (see diagram). Black will play 8...Nb4 or 8...Ne7 and follow up with c6, bolstering his pinned knight on d5. If Black plays 8...Nb4, White can force the b4 knight to abandon protection of the d5 knight with 9.a3?! Nxc2+ 10.Kd1 Nxa1 11.Nxd5, sacrificing a rook, but current analysis suggests that the alternatives 9.Qe4, 9.Bb3 and 9.O-O are stronger. White has a strong attack, but it has not been proven yet to be decisive.

Because defence is harder to play than attack in this variation when given short time limits, the Fried Liver is dangerous for Black in over-the-board play, if using a short time control. It is also especially effective against weaker players who may not be able to find the correct defences. Sometimes Black invites White to play the Fried Liver Attack in correspondence chess or in over-the-board games with longer time limits (or no time limit), as the relaxed pace affords Black a better opportunity to refute the White sacrifice.

Sam earned $40 on his investment of $400. He earned 5% interest on his investment. How long did Sam leave his money in the bank?
gogolik [260]

Answer:

2yrs

Step-by-step explanation:

Given parameters:

Amount of interest earned  = $40

Principal  = $400

Interest rate  = 5%

Unknown:

Time taken for the money to be in bank = ?

Solution:

   The formula for interest is given as:

         I = \frac{PRT}{100}  

    Where I is the interest

              P is the principal

               R is the rate

               T is the time

    So;

    100I  = PRT

       T  = \frac{100I }{PR}   = \frac{100 x 40}{400 x 5}  = 2yrs
