Given that the time now is 11:45 a.m, the smallest and between the hour and minute hand on the o'clock will be given by:
60 min=360 degrees
the time between the min hand and the hour hand is 10 min;
thus the angle will be:
10/60*360
=60 degrees
Answer:
The sum of 8 geometric sequence is 959780
Step-by-step explanation:
We are given
this sequence is geometric
-4 , 24 , -144
First term is -4
so, 
now, we can find common ratio

we can use formula

n=8
now, we can plug values

now, we can simplify it
and we get

Answer:
2a to the second power + 3a
Step-by-step explanation:
Answer:
1.) Circumference of circle A = 131.95 metre
2.) Circumference of circle B = 175.93 metre
3.) Yes. Radius is proportional to the circumference.
Step-by-step explanation: Given that Circle A has a radius of 21 meters and Circle B has a radius of 28 meters
Circumference of a circle = 2πr
For circle A
Radius r = 21
Circumference = 2 × 3.143 × 21
Circumference = 131.95 metre
For circle B
Circumference = 2 × 3.143 × 28
Circumference = 175.93 metre
Is the relationship between the radius of a circle and the distance around the circle the same for all circles? YES
Because the radius of the circle is proportional to the distance around them ( circumference ) for all the circle. That is, the larger the radius, the larger the circumference
Answer:
k = -4
Step-by-step explanation:
(k - 10)/2 = -7
First: multiply by 2 to get rid of the denominator
2(k - 10)/2 = 2(-7)
k - 10 = -14
Next: add 10 to both sides to isolate k
k - 10 + 10 = -14 + 10
k = -4
