Answer:
300%.
Step-by-step explanation:
Suppose the population is 100, then it rises to 300 after one hour.
So the requires percent is (300/100) * 100
= 300%.

Answer:
D) 45 and 1.2
Step-by-step explanation:
The "varies inversely" relationship is described by the equation ...
y = k/x . . . . . . y varies inversely with x (and vice versa)
The value of k can be found from known values of x and y:
xy = k . . . . . . multiply the above equation by x
(10)(6) = k = 60 . . . . using the given values
__
To check if a given pair of numbers satisfies ...
y = 60/x
you can multiply them together to see if the product is 60.
(A) 12×5 = 60
(B) 15×4 = 60
(C) 25×2.4 = 60
(D) 45×1.2 = 54 . . . . . not a possible pair of corresponding values.
45 and 1.2 are not a possible solution for x and y.
Answer: 51.9 degrees
Step by step explanation:
Sin(71)/35.6=Sin(x)/21.3
21.3Sin(71)=35.6Sin(x)
21.3Sin(71)/25.6=sin(x)
Sin^-1(21.3Sin(71)/25.6)=x
51.87827502 degrees=x
51.9= angle x
The area of a parallelogram can be found using the formula
.
We know that
and
, so we can divide 12 by 5¼ to get b.
Let's put 5¼ as an improper fraction to make dividing easier.
5 wholes = 20 fourths. 20 + 1 = <u>21 fourths</u>.
Dividing by a fraction is the same thing as multiplying by its reciprocal.
To find the reciprocal we flip the numerator and the denominator and get 4/21.
4/21 × 12 = 48/21 which as a simplified mixed number is
