a. to find the percentage, we take the total amount of white squares and divide it over the total number of squares. So it's 5/20 = 25%
b. If 80% of the cost is laying the tiles, that means the rest of the cost comes in buying the tiles (20%) this means that the ratio of that would be
80% : 20%
or simplified to
4% : 1%
Answer:
RT = 81
Step-by-step explanation:
RT = RS+ST
13y – 23 = ( 6y+2) + (3y+7)
13y – 23 = 9y +9
13y – 9y = 9+23
4y = 32
y = 32/ 4
y=8
RT= 13y – 23 = 13 (8) – 23 = 104 – 23 = 81
___o___o___
If you want RS , ST
RS = 6y +2 = 6(8)+2 = 48 +2=50
ST = 3y +7 = 3(8) +7 = 24 + 7 =31
I hope I helped you^_^
All together is - 60 cupcakes
Jim placed - 0.45 or 5 cupcakes
Dora placed - 10
Ada placed - 25% or 15
Kim placed the remaining and that is - 30
10 + 5 = 15 and 15 + 15 = 30 so Kim had 30 that means 30 + 30 = 60 cupcakes
Kim is your answer
Answer: There are 9 outcomes in this experiment.
Step-by-step explanation:
Rock-Paper- Scissor is a simple game, in which Rock beats scissor, scissor beats paper, paper beats rock. If any two people made the same gesture it will be a tie.
So if two roommates are playing the game , total outcomes in the sample space = 3 x 3 [By fundamental principal of counting]
= 9
Hence, there are 9 outcomes in this experiment.
So... our numbers... let's say the first one is hmmm "a"
so the second and subsequent are
a
a+1
a+2
a+3
a+4
there, 5 consecutive whole numbers or integers for that matter
now, we know the sum of the square of the first three,
is the same as the sum of the square of the last two
so
do a binomial theorem expansion on those, solve for "a"
