Answers
Answer:
r = 0.05 or 5%
Step-by-step explanation:

450 = 9000 · r
450/9000 = r
r = 0.05 or 5%

it rained nine days in the month of april .based on this ,what is the probaility that is does not rain on the first day of may?
Answers
==========================================================
Explanation:
There are 30 days in April. Since it rained 9 of those days, the empirical probability of it raining in April is 9/30 = (3*3)/(3*10) = 3/10.
If we assume that the same conditions (ie weather patterns) hold for May, then the empirical probability of it raining in May is also 3/10. By "raining in May", I mean specifically raining on a certain day of that month.
The empirical probability of it not raining on the first of May is therefore...
1 - (probability it rains)
1 - (3/10)
(10/10) - (3/10)
(10-3)/10
7/10
We can think of it like if we had a 10 day period, and 3 of those days it rains while the remaining 7 it does not rain.

16 out of 16016/160*100% = 10%If the surface area of the cone shown below is 628.32m2, find its volume.
Answers
Answer:
Solution given:
diameter [d]=16m
radius [r]=8m
let slant height =l
surface area =628.32m²
πr(r+l)=628.32m²
π×8(8+l)=628.32
8+l=628.32/(8π)
8+l=25
l=25-8
l=17m
now
height of cone [h]=√{17²-8²}=15m
Again
Volume of cone =⅓πr²h=⅓×π×8²×15=320π 0r 1005.31m³
The required volume is 320π 0r 1005.31m³
The Volume of the given Cone is: 1005.469 cubic. cm.
V=1005.469 cubic. cm.
What is Volume of cone?The volume of a 3 -dimensional solid is the amount of space it occupies.
The volume V of a cone with radius r is one-third the area of the base B times the height h .
V= [tex]\frac{1}{3} \pi r^{2} h[/tex]
Surface area of cone= 628.32
[tex]\pi r(l+r)[/tex]= 628.32
3.14 x 8 (l + 8)= 628.32
l+8= 25.01
l= 17.01 cm
height= 15.01 cm
Now volume of cone,
V= [tex]\frac{1}{3} \pi r^{2} h[/tex]
= [tex]\frac{1}{3} *3.14 *8^{2}* 15.01[/tex]
=1005.469 cubic. cm.
volume of cone, V= 1005.469 cubic. cm.

2x + 50 = 180
just in case:
2x + 50 = 180 *subtract 50 from both sides*
2x = 130 *divide by 2*

Find the prices of the pots and succulents.
Answers
S=15
System-
Equation 1: 2p + 4s = 76
Equation 2: p + 3s = 53
Solve by elimination.
2p + 4s = 76
-2(p + 3s) = 53
Equation 2 turns into -2p - 6s = -106
2p + 4s = 76
-2p - 6s = -106
Combine alike terms
-2s = -30
s = 15
Use one of the original equation and plug “s” in.
p + 3(15) = 53
p + 45 = 53
p= 8
