Answer:  Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Grade    Number of Students

4th                   45

5th                   25

6th                   60

7th                   50

8th                    60

9th                    45

Total number of students is given by

45+25+60+50+60+45 = 285

So, the central angle for 9th grade would be

\dfrac{45}{285}\times 360^\circ\\\\=56.8^\circ\\\\\approx 57^\circ

Hence, Option 'C' is correct.

Answer: velocity-time graph

Step-by-step explanation: The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).

HELP PLEASEEEEEEE it’d be rlly appreciated
Alex_Xolod [135]

Answer: they have

et n = number of nickels

Let d = number of dimes

given:

(1) +n+%2B+d+=+45+

(2) +5n+%2B+10d+=+360+

-------------------

Multiply both sides of (1) by 5

and subtract (1) from (2)

(2) +5n+%2B+10d+=+360+

(1) +-5n+-+5d+=+-225+

+5d+=+135+

+d+=+27+

and, since

(1) +n+%2B+d+=+45+

(1) +n+%2B+27+=+45+

(1) +n+=+45+-+27+

(1) +n+=+18+

She had 18 nickels and 27 dimes

check:

(2) +5%2A18+%2B+10%2A27+=+360+

(2) +90+%2B+270+=+360+

(2) +360+=+360+
