Answer:
19 seconds.
Step-by-step explanation:
Given that the clock was exactly on time at 7am, and at 1pm the clock was 228 seconds late, to determine, at that rate, how slow was the clock half an hour, the following calculation must be performed:
1 PM = 13:00
13 - 7 = 6
228/6 = 38
38/2 = 19
Thus, every half hour the clock is delayed 19 seconds.

Step-by-step explanation:
Total students = 90
<u>Students who like at least one of the fruit:</u>
- 20 + 16 + 8 + 4 + 5 + 10 + 2 = 66
<u>Number of students do not like any of the fruits:</u>
Answer:
A) -4
B) 4 units apart
C) no values of x
Step-by-step explanation:
1) slope of m: (3-2)/(10-8) = ½
m(x) = ½x + c
2 = ½(8) + c
c = -2
m(x) = ½x - 2
m(16) = 6
h(4) = (4-2)²/2 = 4/2 = 2
h(4)-m(16) = 2-6 = -4
B) y-intercept of:
*h(x) = ½(0-2)² = 2
*m(x) = -2
from the equation found before
2 - (-2) = 4 units apart
C) m(x) = (x-4)/2
m(x) > h(x)
(x-4)/2 > ½(x-2)²
x-4 > x²-4x+4
x²-5x+8 < 0
(x - 2.5)² + 1.75 < 0
Never negative
Answer:
see below
Step-by-step explanation:
In decimal, the values of the fractions are ...
-0.2 = -0.200
-3/7 = -0.429
-2/8 = -0.250
So, in a, b, c order, they are ...
a = -3/7
b = -2/8
c = -0.2
