15-8 which is seven and then u better know how to do the rest
The numbers in this addition problem are given in scientific notation. First we should convert these values into decimal notation by moving the decimal points over by the power of 10 that the significant figures are being multiplied by.
The first number is being multiplied by 10^3, so the decimal place will move to the right 3 places to become 1240.
The second number is being multiplied by 10^4, so it becomes 23000.
Add these together to get:
1240 + 23000 = 24240
The answer is 24240.
<u>Answer</u>
4.71 cm²
<u>Explanation</u>
Area of a circle = πr²
Where r is the radius of the circle.
For a sector which is part of a circle, its area is given by;
Area of a sector = (Ф/360)πr²
where Ф is the angle making the sector at the center of the circle.
∴ Area of a sector = (Ф/360)πr²
= 60/360 × π × 3²
= 1/6 × π × 9
= 4.71 cm²
The Greatest Common Factor of GCF of 20 and 45 is 5
I believe the correct answer is C. The variation of the function y/x^2=5 would be stated as " y varies directly as the square of x." It is a direct variation since as the y value increases, the value of x increases but increases raise to the power of 2.
