jek_recluse [69]

Answer:

The mom ate 49 fish.

Step-by-step explanation:

This question can be solved by a rule of three.

a mother otter is fed 7 fish for every 2 fish for its cub

if  a cub has eaten 14 fish , how many fish did the mother eat ?

For each 2 fish cub eats, the mon eats 7. How much has the mom eaten if the cub has eaten 14?

So

2 - 7

14 - x

2x = 14*7

Simplifying by 2

x = 7*7

x = 49

The mom ate 49 fish.

Suppose that ∠BNR and ∠RNA are adjacent angles where m∠BNR=12w-19,
wariber [46]

Answer:

Step-by-step explanation:

Sum of interior adjacent angle is 180 degrees.

Given  

m∠BNR=12w-19,

m∠RNA= ¼(w+199)

m∠BNA=2(12w-19).

Substitute

m∠BNR+m∠RNA=

¼(w+199)+12w-19, = 2(12w-19).

W+796+48W-76 = 96W-152

49W-96W = -152+76-796

-47W = 872

W = 872/47

W = 18.55

The number a exceeds the number b by 50 percent. By what percent is the number b smaller than the number a?
inna [77]

Answer:

   33 1/3 percent smaller

Step-by-step explanation:


The number a exceeds the number b by 50 percent.

a = b + b*.5

a = b(1.5)

Divide by 1.5

a/1.5 = b

2/3a =b



We want to find (a-b)/a  to find the percent decrease

                           (a-2/3a)/a *100percent

                             (1/3a)/a* 100 percent

                                  1/3 * 100 percent

                                     33 1/3 percent smaller
