Well, you need to add together how much wood you need. one side is 4 1/4 long & the other side is 5 1/8 long. you need to find a common denominator before you add.
multiply the numerator and denominator of the first number by 2.
4 1/4 × 2 = 4 2/8
multiply the numerator and denominator of the second number by 1 because you already have common denominators.
5 1/8 × 1 = 5 1/8
now you can add.
4 2/8 + 5 1/8 = 9 3/8
9 3/8 does not simplify.
therefore Mrs. Edwards only needs to buy the smallest amount of wood available, which is 12 inches.
Answer:
11,232,000 different plates
Step-by-step explanation:
Figure it out like this:
2letters × 3digits × 1letter
Nothing can repeat. There are 26 letters in the alphabet. If we use 1 of those letters, then there are only 25 letters left to choose from. That's why we start with 26 × 25.
Now for the digits, we have 10 choices for the first digit, then 9 choices for the second digit, then 8 choices for the third digit. That's why we follow the letters with 10 × 9 × 8.
For the last letter, we had 24 choices left, so the whole thing is found by multiplying:
26 × 25 × 24 × 10 × 9 × 8 × 24 = 11,232,000
3x/2 + x/1 = 9/4
(3x+2x)/2=9/4
5x/2 = 9/4
10x = 9
x = 9/10
You can use the Law of Cosines, if only one of which is missing: three sides and one angle. Hence, if the known properties of the triangle is SSS(side-side-side) or SAS (side-angle-side), this law is applicable.
You can use the Law of Sines if you want to equate the ratio of the sine of an angle and its opposite side. This can be used if the known properties of the triangle is ASA(angle-side-angle) or SAS.
The ambiguous case is the SAS triangle. This could be easily solved using Law of Sines than Law of Cosines. Take for example: side a = 4, side b = 10, angle A = 23°. Then, we can determine angle B through Sine Law.
sin 23°/4 = sin B/10
B = 77.64°
