You can remove the % sign if you divide the number by 100:
This is because % is defined as 1/100, and the name (per-cent) actually meant this originally!
we can also simplify it: let's divide it by 4:
Answer:
650ml
Step-by-step explanation:
30% = 0.30
0.30 x 500 = 150
500 + 150 = 650
For this problem you have yo set up two equations.
White shirts = w Yellow shirts = y
1st: w + y = 21
2nd: 9.95w + 11.50y = 235.30
Now we're going to do system of equations using substitution.
If w + y = 21, then y = 21 - w
If y = 21 - w, then you can substitute this in the second equation for y.
9.95w + 11.50(21 - w) = 235.30
9.95w + 241.5 - 11.50w = 235.30
-1.55w + 241.5 = 235.30
-1.55w = -6.2
w = 4, so 4 whites shirt were sold.
Now I'm finding out how many yellow shirts were sold using one of the two equations at the top.
w + y = 21
4 + y = 21
y = 17
So 17 yellow shirts were sold and 4 white shirts were sold.
Answer:
08, 15, 17
Step-by-step explanation:
Use the Pythagorean theorem.
Where the sum of both legs squared is equal to the hypotenuse squared.
8² + 15² = 17²
64 + 225 = 17²
289 = 17²
289 = 289
The side lengths that represent Pythagorean triplets are 08, 15, 17.
