Answers

Answer 1

Answer: Given:
8 2/3 hours per month
12 months in a year.

Number of hours she play soccer in a year.

8 2/3 must be converted to improper fraction.

((8*3)+2)/3 = 26/3

26/3 * 12 = (26 * 12)/3 = 312/3 = 104

Yolanda spends 104 hours in a year playing soccer.

Answer 2

Answer: (8+2/3)*12=96+2*12/3=96+2*4=96+8=104
Approximatively 104h per year

A farmer decides to enclose a rectangular garden, using the side of a barn as one side of the rectangle. What is the maximum area that the farmer can enclose with 80 feet of fence? What should the dimensions of the garden be to give the area?

Answers

garden
max area is if the sides are as equal as possible
so he should try to make a square (ideal is a circle, but barn walls are normally straight)
squaer perimiter=4 times legnth of 1 side
perimiter=amount of fencing=80
80=4s
divide 4
20=s
one sides=20

area=legnth times width
in squaer, legnth=width

20=legnth
20=width
area=20 times 20=400

dimetions are 20ft by 20ft to give 400ft^2
(fun fact, if it were a circle, the area would be about 509.5ft^2)

answer is 20ft by 20ft and area=400ft^2

6. A choc frog is 11 cents dearer than a green frog. 3 green frogs and 2 choc frogs cost 57 cents. What is the cost of a choc frog I cents?

Answers

1. 3 consecutive odd numbers are x, x+2, x+4
x+x+2+x+4=405
x+x+x+2+4=405
3x+6=405
3x=399
x=133 (smallest of the numbers)

2. Let the number =x
5x-7=7x+13
-7-13=7x-5x
-20=2x
x=-10

3. Chris earns 4v, Vesna earns v, Dawn earns v-17
4v+v+v-17=163
6v-17=163
6v=180
v=$30
Chris earns 4v=$120

4. Ginny is x years old, Percy is x+8 years old
  In 10 years time, Percy will be x+8+10=3x
  x+18=3x
  18=2x
x=9
  Percy is 9+8 years now=17 years

5. Perimeter of the triangle=sum of its sides
  385=x+2+x+2+x+6
