To find an angle you need to use trig ratios (tan, sin, and cos).
In this case to find ∠R you would need to use sin or cos because both of the legs are not across or adjacent to it.
To find ∠R you would need to do the "opposite" formula which would be (for sin) 5/13 <span>≈ 0.38.. asin = 22.26</span>
By geometry, there is a relationship between the tangent PA and the segments PB and PE, namely
PA^2=PB*PE
so
PE=PA^2/PA=6^2/4=9
BE=PB-PE=9-4=5
A. 8 pizza pies at 10 pc. per pie = 80 available pieces
B. Let X be the number of children. Number of pieces eaten = 5 per child = 5X.
c. 22 pieces are left over.
D. Combine line A and line C. Total number of pieces eaten = 80 original minus 22 left over. Result 58 pieces were eaten by X children: 58 = 5X.
E. Solve the equation 58 = 5X by dividing both sides by 5.
WHOOPS! Is this a trick question? Solving the above results in the answer that there are 11.6 children at the party. Hmmm. That 0.6 child is a question mark for me.
Looks like someone miscounted the pizza slices. Or omitted some pertinent information. But, I’m sure there is a logical answer.
The answer is 33.5 or 33minutes and 30 seconds
2/45= 22.5
22.5 +11=33.5
Answer: a) 300000 b) 200 c) 20000
Step-by-step explanation:
Round so that there is only 1 sig. fig. in the answer
a) 300000 (rounded up to 300,000 not 280,000 as there would be 2 sig figs, 2 and 8)
b) 200 (rounded down)
c) 20000 (rounded up to 20,000 not 18,000 as there would be 2 sig figs, 1 and 8)
The trailing zeroes do not count as sig. figs. so the above answers all have only one sig. fig.
