The height of the lighthouse is :
h = 14 ft ( same as the distance from Kelly to a lighthouse ).
tan y = 14 / ( 14 + 12 ) = 14 / 26 = 0.5384615
y = tan^(-1) 0.5384615 = 28.3°
Answer: y = 28.3°
Answer:
Water a tank can hold = 14 1/2 = 29/2
Volume of bucket 1 1/4 = 5/4
The expresson can be
29/2 / 5/4
No. of buckets used = 29/2 x 4/5
The system<span> is : (i) x^{2} +</span>y<span> ^{2} =</span>6<span> and (ii) x^{2} -</span>y=6<span> rewrite </span>equation<span> (ii) as x^{2}=</span>y+6<span> and substitute x^{2} in </span>equation<span> (i) with </span>y+6<span> so </span>equation<span> (i) becomes (</span>y+6)+y<span> ^{2} =</span>6 y<span> ^{2} +</span>y<span>=0 factorize to find the roots</span>
Answer:
they will play together again in 28 days
Step-by-step explanation:
Answer:
I think the equation is written as 3r + 2.5p, where r is the number of roses and p is the number of petunias. To find the total cost, substitute 777 to r and 888 to p. The total cost would then be:
Total Cost = 3r + 2.5p
Total Cost = 3(777) + 2.5(888)
Total Cost = 4551
The total cost would be $4,551.
