21.5in^2 is your answer.
the formula for a circles area is pi•r^2
since the square is the same height as the circle, we can conclude that side length of the square is equal to the diameter of the circle.
the radius (r) is half the diameter.
so using our area formula we will write our formula as 3.14•5^2 and your answer is 78.5. Thats the area of the circle but we are looking for the area of the shaded region. find the area or the square by squaring the side length 10^2 or 10•10. to get the area of the square, 100. now subtract 100-78.5 to get the area of the shaded leftover region.

John is 1 8 meter shorter than Paul, and Paul is 0.25 meter taller than Andrew. If John’s height is 1 3 4 meters, what is Andrew

9966 [12]

Answer:

Andrew's height is $1\frac{5}{8}$ meters

Explanation:

We know that John's height is $1\frac{3}{4}$ meters

We are given that:

John is $\frac{1}{8}$ meters shorter than Paul

This means that:

Paul's height = John's height + $\frac{1}{8}$

Paul's height = $1\frac{3}{4} + \frac{1}{8} = 1\frac{7}{8}$ meter

We are given that:

Paul is 0.25 meters taller than Andrew

This means that:

Andrew's height = Paul's height - 0.25

Andrew's height = $1\frac{7}{8} - 0.25 = 1\frac{5}{8}$ meters

Hope this helps :)

Solve the quadratic equation. 22 – 9 = 16

Colt1911 [192]

Answer:

22-9=16

so,

22-9

is 16

then you would take

16=16

so, you would have to divide the 2 numbers

then 1 is your answer

when asked to write a point slope equation for a line passing through the points (-3,-5) and (2,4) a student wrote y-4=-9/5(x-2)

Eduardwww [97]

(-3,-5)(2,4)
slope(m) = (4 - (-5) / (2 - (-3) = (4 + 5) / (2 + 3) = 9/5

y - y1 = m(x - x1)
slope(m) = 9/5
(2,4)...x1 = 2 and y1 = 4
sub
y - 4 = 9/5(x - 1)....this is the correct answer

the student figured the slope wrong....it is 9/5...not -9/5
