Time is 9:42 a.m. when they meet will at the starting point again.
We have, Cheko and Sharko started running at the same time and starting point. The shape of ground or stadium is circular. Time taken by Cheko to complete the one round of stadium
= 7 minutes
Time taken by Sharko to complete the one round of stadium = 6 minutes.
At 9.00 a.m, both are start running together. We have to calculate time they will meet at the starting point again. So, they will starting together after LCM ( 7, 6) minutes. LCM stands for least common multiple of 7 and 6. The factors of 7 and 6 are the following, 7 = 1×7
=> 6 = 2× 3 × 1
So, LCM (6,7 ) = 2×3×7×1 = 42 minutes
Thus, the again starting time = 9:00 a.m. + 42 minutes = 9: 42 a.m.
Hence, the required time is 9: 42 a.m.

Nice work on getting part (a) correct.
The 261% falls in the "250-300%" range, so they pay 8.5% of their yearly income toward health insurance.
8.5% of $65,500 = 0.085*65500 = 5567.50
That represents the yearly contribution. Divide that by 12 to find the monthly contribution.
5567.50/12 = 463.95833 = 463.96 approximately
Then round to the nearest dollar to get 464
Answer to part (b) is 464a library has 2500 books.40% of the books are fiction.How many books are not fiction books
A library has 2500 books.40% of the books are fiction, number of not fiction books are 1500.
A percentage is a relative figure that represents one tenth of a quantity. Since one percent (symbolised as 1%) is equal to one tenth of anything, 100 percent stands for everything, while 200 percent refers to double the amount specified.
Total amount of book in library are 2500 ,
Out of that 40% are fiction so the number of the non fiction books are 60%
so 60% of 2500 will give us the value of non fiction books,
Number of non fiction = 2500 x 60%
= 2500 x 60/100
= 25 x 60
= 1500
Therefore, Number of non fiction books are 1500.

A (4,0).B (1.5), and C(-3,-5) are three vertices of a parallelogram ABCD. What is the ordered pair for D, the fourth vertex of the parallelogram?
Answer: In a parallelogram, opposite sides are equal in length and parallel, so if we subtract the vectors AB and BC from each other, we will get the vector for CD.
Given A = (4,0), B = (1.5,0), and C = (-3,-5), we can calculate the vectors AB and BC as follows:
AB = B - A = (1.5, 0) - (4, 0) = (-2.5, 0)
BC = C - B = (-3, -5) - (1.5, 0) = (-4.5, -5)
Next, we subtract these vectors to find the vector for CD:
CD = BC - AB = (-4.5, -5) - (-2.5, 0) = (-2, -5)
Finally, we add the vector CD to vertex C to find vertex D:
D = C + CD = (-3, -5) + (-2, -5) = (-5, -10)
So, the ordered pair for vertex D is (-5, -10).

$2,250 was invested at 2% and the remaining $3,500 was invested at 12%. The combined interest earned amount for the first year was $475.
The financial planner invested $5,750 of the couple's money. Let x be the amount of money invested in the savings account paying 2% annual simple interest and y be the amount of money invested in the riskier mini-mall development plan paying 12% annual simple interest. Since the combined interest earned for the first year was $475, we can write the equation 2x + 12y = 475. Since the total amount of money invested was $5,750, we can add the equation x + y = 5,750 to our system of equations. Solving the system of equations yields x = 2,250 and y = 3,500. Thus, $2,250 was invested at 2% and the remaining $3,500 was invested at 12%. The combined interest earned for the first year was $475.

C′(−3, 6)
C′(−3, 14)
C′(−1, 6)
C′(−1, 14)
Answer:
(d) C'(-1, 14)
Step-by-step explanation:
You want the coordinates of C' after the point C(-1, -6) is reflected across the line y = 4.
ReflectionReflection across the horizontal line y=4 will not change the x-coordinate of the point, so C' has an x-coordinate of -1.
The point (-1, 4) on the line of reflection will be the midpoint of C and C', so we have ...
(C +C')/2 = (-1, 4)
C +C' = 2(-1, 4) = (-2, 8) . . . . .multiply by 2
C' = (-2, 8) -C
C' = (-2, 8) -(-1, -6) = (-1, 8+6)
C' = (-1, 14)
__
Additional comment
Effectively, the reflection across the line y=4 is the transformation ...
(x, y) ⇒ (x, 8 -y)
Answer:
C'(-1, -6).
Step-by-step explanation:
the reflection across y = 4 for point C(-1, -6).
When reflecting a point across a horizontal line like y = 4, the y-coordinate remains the same, and the x-coordinate is inverted with respect to the line of reflection.
For point C(-1, -6), the y-coordinate remains -6, and the x-coordinate is inverted across y = 4:
New x-coordinate = -1
So, the reflected image of point C across y = 4 is C'(-1, -6).
None of the provided options match this reflection, so it seems there might be an error in the given answer choices. The correct reflection of point C(-1, -6) across y = 4 is C'(-1, -6).

Find a formula for the tenth term in this arithmetic sequence: a1=28 a2=21 a3=14 a4=7
Answer:
an = - 7n+35
Step-by-step explanation:
In an arithmetic sequence, the difference between consecutive terms is constant. To find this difference, we can subtract the first term from the second term and the second term from the third term, etc.
a2 - a1 = 21 - 28 = -7
a3 - a2 = 14 - 21 = -7
Since the difference between consecutive terms is the same, we can conclude that the difference is -7.
The nth term in an arithmetic sequence can be found using the formula: an = a1 + (n-1)d, where d is the common difference.
For this sequence, the nth term can be found as: an = 28 + (n-1)(-7) = 28 - 7(n-1) = 28 - 7n + 7 = 35 - 7n.
So, the formula for the nth term in this arithmetic sequence is an = - 7n+35
