Answer:
The h and v represent the center of the circle at point (h, v), and r names the radius. Specifically, h represents the horizontal displacement — how far to the left or to the right the center of the circle falls from the y-axis.
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
Diameter= 180cm
Circumference of each table
= πD
= 180π cm
Each table can fit
= 180π ÷70
= 8 guests (nearest whole number)
Since there are 18 tables, total number of guests
= 8(18)
= 144 guests
Since there are only enough tables to sit 144 guests, there are not enough tables to fit 145 guests.
Note that we cannot take the sum of the circumference for 18 tables than divide by 70 to see how many guests can fit because a guest can only be sitted on one table.
If that was done,
Total circumference
= 180π(18)
= 10179 cm (5 s.f.)
Total number of people
= 10179 ÷70
= 145 people (3 s.f.)
This is incorrect.
The answer would be 9 because 9x2 is 18 and 9x5 is 45.
Answer:
14.8
Step-by-step explanation:
13^2 + 7^2 = 218
sqrt(218) = 14.76
He lifts for 11 more minuets each day.
51 + 11 = 62
He lifted for 62 minuets on Friday.
62 + 11 = 73
He lifted for 73 minuets on Saturday.
