I think the answer is 8,100,000
Answer:
15 and 1
Step-by-step explanation:
x and y are two numbers.
Two equations:
x · y = 15
x + y = 16
Rearrange one of the equations (I'll rearrange the sum equation):
x + y = 16
x = 16 - y
Substitute that to the other equation and solve for y:
x · y = 15
(16 - y) · y = 15
16 - y · y = 15
16 - y² = 15
-y² = 15 - 16
-y² = -1
y² = 1
y = √1
y = 1
Now substitute that to any of the equation and solve for x (in here, I'll choose the multiplication one):
x · y = 15
x · 1 = 15
x = 15
Now verify:
15 · 1 = 15
15 + 1 = 16
This is correct

Answer:
34,000
179,400
39,900
Step-by-step explanation:
In the number 33,762, the 3 is in the thousands place, so we look to the number behind it. If it is less than 5, we round down, and if it is more than 5 we round up.
Since 7 is more than 5, we round up, so our rounded number would be
34,000
Let’s use this logic for the rest of these numbers
179,406
4 is in the hundreds
Previous number in 0 which is less than 5, so it rounds down
179,400
39,994
9 is in the tens place
Previous number is 4 which is less than 5, so it rounds down
39,990
Answer:
8π in
Step-by-step explanation:
The Area of a Circle is πr². In this case, we're given the area as 16π, so the radius is 4 because the square root of 16 is 4.
The Circumference of a Circle is 2πr. Since the radius is 4:
Therefore, the circumference is 8π inches.
