Answer:
k = 5
Step-by-step explanation:
First three terms of an AP are 3k-1, 4k+1, 6k-2.
First term is 3k-1
For an AP,
a₂-a₁=a₃-a₂
4k+1-(3k-1)=6k-2-(4k+1)
4k+1-3k+1=6k-2-4k-1
k+2=2k-3
Separating like terms,
k-2k=-3-2
-k=-5
k = 5
So, the value of k is 5.
He will earn $126 in interest.
How did I solve this:
Find the decimal of 4%:
4% = 0.04
Multiply 0.04 times 525:
0.04 x 525 = 21
Multiply $21 times 6 years:
21 x 6 = 126
126 is your correct and finale answer.
Hope this helps! =)
Based on the given equation above, get the value of x first so that this value can be substituted to the second equation. Value of x can be obtained by taking the arc sin of 7/11 which gives an answer of 39.52 degrees. Substituting this value to the second equation cos (90-39.52) gives an answer equals to 7/11
Im not sure what u are asking for but u can multiply5 kilometers by 25 min but if u are doing the rate then divide 5 by 25 giving u 5 kilometers for every minut that passes

Answer:
length= 100 width=70
Step-by-step explanation:
The perimeter of a rectangular field is 340 yds.
The length is 30 yds longer than the width.
2(l + w) = 340
l + w = 170
w + 30 + w = 170
2w = 140
w = 70
Hence the dimensions:
Length: 100 yds.
Width: 70 yds.
