Answer:
Step-by-step explanation:
There are 100 small squares in each large square .
On the first row we count 11 dark squares so the fraction of these is 11/20.
You then convert 11/20 to a decimal , percent and words ( 11 pieces out of 100
pieces)
For the second part we color in 20 small squares of the big square. ( 2/10 = 20/100).
Third row: I think it must be 80 pieces out of 100 :- color in 80. Fraction = 80/100 = 4/5.
For the last one color in all hundred squares on first big square and 50 on the second.

Step-by-step explanation:
i gotchu keep these coming
for x multiply 6 by sin(45) = 3sqrt(2) = 4.2426
for y since it is a right triangle with 45 degree angle both legs are equal
so y = x
Parallelogram square rectangle
Answer:
tall candles = 39
Short candles = 52
Step-by-step explanation:
let tall candles be x
and short candles be y
No. Of candles sold = x + y =91
Money made from candles will be equal to = 8x + 5y = $572
These both are simultaneous linear equations.
x + y =91 ( multiply by 5)
5x + 5y = 455
8x + 5y = $572
Subtract them:
-3x = -117
x = -117/3
x = 39
put value of x in
x + y = 91
39 + y = 91
y = 91 - 39
y = 52
x shows tall candles so they are 39
y shows short candles so they are 52
