Answer:
A.
Step-by-step explanation:
Answer:
It would be C, 64.387
Step-by-step explanation:
First, you have to solve 7x1/1000. This equal to 7/1000 which should be converted into decimal form (since all the answers are in decimal form). 7/1000 is 0.007 in decimal form.
It is 0.007 since in 7/1000, the denominator is 1000, making 7 in the thousandths place (the 3rd digit to the right of the decimal point).
The only number that contains 0.007 is the 3rd one, making it your answer.
Answer:
8 rooms
Step-by-step explanation:
39 - 7 = 32. 32/4 per room is 8 rooms.
Answer:
The product of the tens in these two numbers is 4
Step-by-step explanation:
TO find this, first we need to find the number in the tens place for each of them. The tens place is the second from the decimal point.
14
42
Now we take these two and multiply them together to get the product.
1 * 4 = 4
Answer:
x = - 2
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
To obtain this form use the method of completing the square
Given
x² + y² + 4x - 6y = b ( collect x and y terms together )
x² + 4x + y² - 6y = b
add ( half the coefficient of x/ y terms )² to both sides
x² + 2(2)x + 4 + y² + 2(- 3)y + 9 = b + 4 + 9
(x + 2)² + (y - 3)² = b + 13 ← in standard form
with (h, k) = (- 2, 3)
Thus x- coordinate of centre is x = - 2
