For the first digit you have 10 options (0..9).
For each next digit you can't choose the same digit, so you have 9 options.
So number of combinations is 10*9*9*9*9 = <span>65610</span>
Answer:
7/4 - 8/3 - |1/6 - 3/4|
criss cross both sides to find their respectively simplified forms.
let's do (7/4 - 8/3) first.
(4 × 8) - (7 × 3) / 3 × 4
= 32 - 21 / 12
= 11 / 12.
then simplify |1/6 - 3/4| by criss crossing the pure numbers inside the absolute value.
Remember, no number can get out of the absolute value while being negative.
= |6 × 3 - 4 / 24|
= |18 - 4 / 24|
= |14/24|
= | 7 × 2 / 12 × 2 |...cancel the 2's
= |7 / 12| --> 7/12
11 / 12 - 7 / 12
= 4 /12
= 4 × 1 / 4 × 3....cancel the 4's
= 1 / 3.
Answer:
C
Step-by-step explanation:
Since its a perfecr square root
Answer:
by multiplying or dividing
Step-by-step explanation:
Two ratios that have the same value are called equivalent ratios. To find an equivalent ratio, multiply or divide both quantities by the same number. It is the same process as finding equivalent fractions.
X = 8
y = 40
the two base angles are equal to each other so you would do 5x = 40 and solve for x
a triangle has 180 total degrees. 40*2 = 80
180 - 80 = 100
2y + 20 = 100
2y = 80
y = 40
