Unlike the previous problem, this one requires application of the Law of Cosines. You want to find angle Q when you know the lengths of all 3 sides of the triangle.
Law of Cosines: a^2 = b^2 + c^2 - 2bc cos A
Applying that here:
40^2 = 32^2 + 64^2 - 2(32)(64)cos Q
Do the math. Solve for cos Q, and then find Q in degrees and Q in radians.
8x-4 and 4(2x-1)
4(2x-1) the four needs to be distributed in the parentheses.
4*2x=8x
4*(-1)=(-4)
8x-4=8x-4
If rounded to the nearest 100,000th it would be 600,000
if rounded to the nearest 10,000th it would be 550,000

Plz name me brainlieset thank you
Step-by-step explanation:
55% of the tables would be 33 tables times 10 chairs equals 330 Chairs That mean 60 Tables -33 tables Leaves you with 27 tables Times 8 Chairs Equals 216 Chairs So 330 and 216Equals 546 chairs
<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>To subtract fractions, we must check if the denominators of both fractions are the same.</u>
- 2/5 - 1/7
- => 2 x 7/5 x 7 - 1 x 5/7 x 5
- => 14/35 - 5/35
<u>Now, let's subtract for the result.</u>
Hence, <u>Option B is correct.</u>
Hoped this helped.
