Answer:
For the one with the 2.5 radius the circumference is 15.7 and the answer for the one with 9 diameter is 28.26
Step-by-step explanation:
Since c=2(pi)(radius)
half of the diameter is the radius and pi=3.14
Answer:
7/3
Step-by-step explanation:
The distances have the ratio ...
(Q -P) = (2/3)(R -P)
Q = P +(2/3)R -(2/3)P = (2R +P)/3
Qy = (2Ry +Py)/3 = (2·0 +7)/3 = 7/3
We need more information.
Step-by-step explanation:
to compare day 1 with day 2 :
100% = 8
1% = 100%/100
25% = 25×1% = 100% × 25/100 = 8 × 1/4 = 2
so, on day 2 he walks 8+2 = 10 laps.
on day 3 he walks then 10-1 = 9 laps.
so, now, to calculate the % decrease compared to day 2
100% = 10
1% = 100%/100 = 0.1
how many % is represented by this 1 lap he was walking less ?
1 / 1% = 1 / 0.1 = 10%
so he had a 10% decrease from day 2 to day 3.
Answer:
Step-by-step explanation:
Hello,
qop(2)=q(p(2))
p(2) = 4+3=7
![q(7) = \sqrt{7+2}=\sqrt{9}=3](https://tex.z-dn.net/?f=q%287%29%20%3D%20%5Csqrt%7B7%2B2%7D%3D%5Csqrt%7B9%7D%3D3)
so
qop(2)=3
and poq(2)=p(q(2))
![q(2)=\sqrt{2+2} = \sqrt{4}=2](https://tex.z-dn.net/?f=q%282%29%3D%5Csqrt%7B2%2B2%7D%20%3D%20%5Csqrt%7B4%7D%3D2)
p(2) = 7
so poq(2)=7
thanks
