Answer:
w=38m
Step-by-step explanation: w ∝ m
w = km
w = number of words
m= minutes
k = constant of proportionality = 28
Hence w=38m
The formula for of a ball is:
S = 4*r^2*pi
or if we express diameter in it:
S = D^2*pi because D=r/2
S1-S2 = (D1^2 - D2^2)*pi
1 = (100 - D2^2)*3,1415
100-D2^2 = 1/3.1415
D2^2 = 100-1/3.1415
D2 = 9.984cm
which means that Diameter will decrease by rate of:
0.016cm/min
Answer:
-2
Step-by-step explanation:
the slope is 2, aka 2/1, aka y goes up twice when x goes up once
Answer:
250 students
Step-by-step explanation:
100 students ÷ 40% = 250 students
8n + 5 = 139
You would re-Arrange it to make it
8n = 139 + 5
Then take minus five to make it look like
8n=134
Next step would be to divide
Divide 8 on both sides which would leave you with
N= 67 over 4
you will have to convert it if you don’t want a fraction
