Answer:To do so, she makes the measurements shown in the figure below.
Step-by-step explanation:
#9 You have to make the fraction a decimal, then multiply 11.8 by 6.5. This is because 11.8 is per hour.
#10 here is a hint, one quarter of an hour is 15 minutes. again change the fraction to a decimal
#11 just multiply the 2 numbers

Answer:

Step-by-step explanation:
The standard form for the equation of a circle is
where r is the radius, and the center is (h, k).
(h, k) = (-1, 2), r = 7

Answer:

Step-by-step explanation:
A line that passes through the point (4,-6) has a slope of 5/-4. Which of the following gives the equation of the line?
With the slope of 5/-4, and the ordered pair (4,-6) :
let m = 5/-4 (slope),
x1 = 4
y1 = -6
We can use those given values into the point-slope formula:
y - y1 = m(x - x1)
Plugging in those values will give you the answer:
y - (-6) =
(x - 4)
Distribute
into the terms inside the parenthesis:
y + 6 =
+ 5
Subtract 6 from both sides to isolate y:
y + 6 - 6 =
+5 - 6
The equation of the line in slope-intercept form is:
Answer:
X is 3
Step-by-step explanation:
15-x=12
X=15-12
X=3
