Step-by-step explanation:
Rule for rounding :
You look at the number next to the place value you are meant to round and if the number is :
=
4 and below you round down.
5 and above you round up
Nearest hundred thousand: 100,000
This is because you look at the number next to the hundred thousand spot which is a 2 so you round down
Nearest ten thousand: 130,000
Same reason as before the number next to the 2 in the number is a 6. So you round up
Nearest thousand: 126,000
The number next to the thousandth place value is a 0 so you round down
Answer:
Step-by-step explanation:
-1 and 1.
They are both 1 away from 0, meaning that the absolute value of both are 1.
Answer:
15.5
Step-by-step explanation:
The plus of two angles in the picture are 90 degrees: 37° + 53°
P(t) = [ 64/ (1 + 11.e⁽⁻⁰ ⁰⁸t⁾]
In 1991, t = 1, hence:
P(t) = [ 64/ (1 + 11.e⁽⁻⁰ ⁰⁸ˣ¹⁾] = 5.7377 billion or rounded 5.74 billion
(Answer A)
There is no image posted. However, I will tell you how to solve for the area of a drum head.
Drum head is a circle shape. We will use the formula of finding the area of a circle to solve for the area of a drum head.
Area of a circle = π r²
π is pi. It is equivalent to 3.14. Though there are still a lot of numbers after 4. To ensure uniformity, π is 3.14
r is radius. It is the line from the center of the circle to the edge of a circle.
if the diameter of a circle is given, simply divide the diameter by 2 to get the radius.
Diameter is the line that starts from one end of the circle to the other passing through the midpoint of the circle.
Example:
The drum head has a diameter of 10. What is the area.
diameter is given, so we need to get the radius: 10 ÷ 2 = 5
Area = π r²
= 3.14 * 5²
= 3.14 * 25
Area = 78.50 square unit
Area is always in a square unit.
