£53 would be the correct answer man
If there are 8 rows, there would have to be 6 in each row to make 48 (8x6=48).
If there had to be 6 white tiles in each of the 8 rows, than 6 out of 6 tiles would be white.
Therefore there would be 0 purple tiles.
Nearest tenth it would be <em><u>360</u></em><em><u /></em><u /> because the ones digit (3) is less than 5 so we have to round down.
Nearest hundred would be <em><u>400</u></em><em><u /></em><u /> because the tens and ones digit (63) is closer to 400 than it is to 300. So we would have to round up.
Hope that helps :)
3a + 3b, for a=2 and b=4 ... The first thing you'd do would be to plug the numbers in -
3 x 2 + 3 x 4
Then multiply them -
6 + 12
Then add -
18.
So your answer should be 18.
Answer:
Step-by-step explanation:
Apply the Pythagorean Theorrem. Find the sum of the squares of the two shortest sides and determine whether this sum equals the square of the longest side:
#19: 5^2 + 12^2 = ? = 13^2
25 + 144 = ? = 169 This is true, so you do have a right triange in #19.
#21: 2^2 + 4^2 = ? = 7^2, or 4 + 16 = ? = 49 This is false. Not a right
triangle.
Apply this same approach (Pythagorean Theorem) to the remaining problems.
