Answer:
60% is the answer 60/100
Step-by-step explanation:
30:50 is the ratio
60% is the percentage
as 60/100 is = 30:50
if it was 30% then the gallons held by her car would be 100
because it was 50 we just multiply the top to make a percentage equal to 30 x 2 = 60.
As 50 x 2 =100
= 60/100
The answer is 0.948

Answer:
It'll take approximately 9.1 minutes
Step-by-step explanation:
The decay of this element can be modeled by the following expression:
m(t) = 540*(1 - 0.179)^t
Where m is the mass of the element in a given minute t. This expression comes from a compounded interest formula, with negative rate, since they will work in the same manner. Therefore to find how long until it reaches 90 g, we need to make m = 90 and solve for t.
90 = 540*(0.821)^t
(0.821)^t = 90 / 540
(0.821)^t = 1/6
ln(0.821^t) = ln(1/6)
t*ln(0.821) = ln(1) - ln(6)
t*ln(0.821) = - ln(6)
t = -ln(6)/ln(0.821) = 9.08452
It'll take approximately 9.1 minutes
Answer: 6 sqrt2
Step-by-step explanation:
Sqrt = square root shorthand.
In a 45-45-90, the legs can be represented as x and the hypotenuse as x root2.
12 = x (sqrt2)
12/sqrt2 = x
Let’s rationalize this by putting the square root on top:
12sqrt2 / 2
Simplify:
6sqrt2
Answer:
Third table
Step-by-step explanation:
For the relationship to be proportional
y/x = constant
First table y/x = 8/4 = 2 then 7/11 doesn't =2 so it is not
Second table y/x =52/5 = 5 then 49/7 doesn't =5 so it is not
Third table y/x = 3/6=1/2 then 5/10 = 1/2 then 7/14 = 1/2 it is proportional
Last table y/x = 6/3 = 2 then 11/8 doesn't =2 so it is not
