<h3>The value after 4 years is $ 2244.16</h3>

<em><u>Solution:</u></em>

<em><u>The decreasing function is given as:</u></em>

y = a(1-r)^t

Where,

y is final value

a is initial value

r is decreasing rate in decimal

t is number of years

From given,

a = 3000

t = 4 years

r = 7 \% = \frac{7}{100} = 0.07

<em><u>Substituting the values we get,</u></em>

y = 3000(1-0.07)^4\\\\y = 3000 \times 0.93^4\\\\y = 3000 \times 0.74805201\\\\y = 2244.15603\\\\y \approx 2244.16

Thus the value after 4 years is $ 2244.16

Emilio bought 5.65 of green grapes and 3.07 pounds of red grapes
NISA [10]

The weight of each bag is 0.545 lb .

<h3>What is weight ?</h3>

Weight in maths is the value of the mass of an object on a measuring scale , It is measured in pound , ounce , kilogram etc.

It is given that

Total weight of green grapes = 5.65 lb

Total weight of red grapes = 3.07lb

Total weight = 5.65 +3.07 = 8.72   lb

Total number of bags = 16

the weight of each bag

= 8.72 / 16

= 0.545 lb

Therefore the weight of each bag is 0.545 lb .

The complete question is

Emilio bought 5.65lb  of green grapes and  3.07lb of red grapes. He divided the grapes equally into 16 bags. If each bag of grapes has the same weight, how much does each bag weigh?

An adventurous dog strays from home, runs three blocks east, two blocks north, one block east, one block north, and two blocks w
Marrrta [24]
<h2>Answer:</h2>

<u>Distance = 360.55 m</u>

<u>Direction = North-East</u>

<h2>Step-by-step explanation:</h2>

In the question,

The adventurous dog starts from O, say.

He moves 3 blocks East = 300 m

then,

2 blocks North = 200 m

1 block East = 100 m

1 block North = 100 m

2 blocks West = 200 m

So,

Distance of the Dog's <u>final position</u> from the <u>initial position</u><u>.</u>

OE is given by,

In triangle OLE, using Pythagoras theorem,

OE^{2}=OL^{2}+LE^{2}\\OE^{2}=(200)^{2}+(300)^{2}\\OE^{2}=40000+90000\\OE=360.55\,m

<em><u>Therefore, the distance of Dog from the Home is 360.55 m and the direction of Dog from Home is North-East.</u></em>
