3y+15=4y-3
Subtract 3y from both sides
15=y-3
Add 3 to both sides
Y=18
4(18)-3
72-3
69 both angles are 69
Hello! here are the basic rules that you need to know to solve these problems:
a diameter is 2 × the radius
the circumference rule is 2×π×radius
I will solve the first question to show how to format.
1: 5/2=2.5
2×2.5×π=5×π=15.7
Answer:
It takes 1.77 hours for the population to double.
Step-by-step explanation:
Equation for population growth:
The equation for population growth, after t hours, with a growth rate parameter of r, as a decimal, is given by:

Growth rato parameter of 48% per hour
This means that
. So



How many hours does it take the size of the sample to double?
This is t for which P(t) = 2P(0). So







It takes 1.77 hours for the population to double.
1.25 kilograms=2.755778 pounds
Answer:

The largest integer is 31.
Step-by-step explanation:
Hi there!
Let <em>k</em> be equal to the smallest of the integers.
Let (<em>k</em>+2) be the next odd integer.
Let (<em>k</em>+4) be the final odd integer.
We're given that the sum of these three integers is 87. Construct an equation:

Combine like terms:

Therefore, the smallest integer is 27. Because the largest integer is k+4, the largest integer is therefore 31.
I hope this helps!
