First you calculate the total cost of the pears:
18,4 pounds x $1,75 = $32,2
Them you add the cost of the pineapple:
$32,2 + $2,89 = $35,09
After this you can divide the total cost (35,09) for 4 friends getting the amount due to each one:
35,09/4 = $8,77
1(Part 1). 29 yards int the 4 plays=7.25 yards penalized each play
1.(Part 2). If they were penalized 10 yards on the 5th play= 7.8 yards penalized on average each play.
2(part 1). Every friend would get 2 1/6 of a cookie.
2(Part 2).If one friend only ate half of her cookies she would have ate 1 1/12 of her cookies.
Hope this helps tell me if you got theses right. please mark brainless.
Suppose we have the repeat decimal 0.123232323.... or 0.123 with a line over the repeated part (check the diagram)
- The first thing we need to do is identify the part of the decimal that repeats, 23 in our case.
- Second, we are going to assign a variable to our original decimal:
.
- Third, we are going to multiply both sides by a power of ten whose denominator will be the number of repeating digits. We know that we have 2 repeating digits (23), so we are going to multiply both sides by
, and
is just 100; therefore we get:
- fourth, subtract our original equation from the second step from the one from above:
Now we can cancel the repeated decimals to get:
- Last but not least multiply both numerator and denominator by a power of ten equals to the decimal digits in the numerator:
We now know how to convert a repeating decimal to a fraction.
I’m gonna go with C sorry if I’m wrong
notes:
c= Colin
s=Sara
g=Gordon
c=g+36 (1)
c : g
5 : 1
c/g=5
c=g*5 (2)
=> from statement (1) => g*5=g+36
5g-g=36
4g=36
g=36/4=9 g=9 sweets
=> from statement (2)=>c=5*9=45 c=45 sweets
s : g
2 : 1
=>s/g=2/1
=> s=2g
s=2*9 s=18 sweets
sum=c+s+g
sum=45+18+9=72 sweets
