An integer is divisible by 3 if...
...if its digits sum to a multiple of 3
An integer is divisible by 4 if...
...if its last two digits are a multiple of 4
An integer is divisible by 6 if...
...if it divisible by 2 and 3
An integer is divisible by 9 if...
...if its digits sum to a multiple of 9
5% as a decimal and fraction
0.05 and 1/20
12.5% as a decimal and fraction
0.125 and 1/8
20% as a decimal and fraction
0.2 and 1/5
distance =
rate x time
to divide powers with the same base...
subtract the exponents and keep the base the same
what happens when an exponent is negative?
Take the reciprocal of the base and change the sign of the exponent
what happens when an exponent is negative?
Take the reciprocal of the base and change the sign of the exponent
what happens when an exponent is negative?
Take the reciprocal of the base and change the sign of the exponent
when can radicals be added and subtracted?
only when the number under the radical is the same! 6radical7 + 2radical7 = 8radical7
to multiply radicals...
...multiply the numbers under the signs and then put a single radical sign over them the new number
to divide radicals...
...divide the two numbers in question and then put them under a single radical
pythagorean triplets (2)
3:4:5 (leg:3 leg:4 hypotenuse:5)
define: parallelogram
a parallelogram has two pairs of equal sides. Opposite angles are equal. Consecutive angles add up to 180
which is bigger: 8/3 or the square root of 7?
to figure this out, square both sides. They compare 64/9 to 7 (or 63/9)...64/9 (or 8/3) is a little bigger
