A = 225<span>°</span> in rectangular form
is written as x = cos (225) = -0.707
y = sin (225) = -0.707
The answer is y = x
This angle is in the third quadrant, x and y have the same amplitude and both are negative.
Let Peters age be x
Phil's age is 1/5x+7---------------------------(i)
Phil's age can also be calculated as
4(1/5x+7)=2x-2--------------------------------(ii)
So,
4/5x+28=2x-2
28+2=2x-4/5x
30=10/5x-4/5x
30=6/5x
x=30*
x=25
Answer:
1:11=11:121
5:2:1=35:14:7
1.5:1.25:2.4=6:5:9.6
Step-by-step explanation:
x/11=11/121 so x equals 1
5/2=x/14 so x equals 35
1.5/x=6/5 so x equals 1.25
1.25:2.4=5/x so x equals 9.6

Step-by-step explanation:
ok
Answer: It will take 11.56 hours .
Step-by-step explanation:
Exponential growth in population or size formula :
, where = initial size
r= rate of growth
t= time period
As per given , we have
grams
At t= 1 , P(t)= 11 grams
Then,
When, the bacteria have tripled in size , P(t) = 3 x10 = 30
Then,
Hence, it will take 11.56 hours .
