First find the area of the rectangle:
8×6=48.
Then find the area of the circle:
(pi)(r)^2= 5^2(3.14)=78.5
To find the area of the shaded area, subtract the are of the rectangle from the area of the circle:
78.5-48=30.5 cm

Which pairs of points would result in a line with a rate of change of 2:1? Select all that apply.

Helen [10]

Answer:

Options A, C, D are true.

Step-by-step explanation:

We have to choose the pair of points from that given in the attached file which will result in a line with a rate of change i.e. slope of 2:1 i.e. 2.

A. The points are (-4,-11) and (-2,-7).

Then the slope of the joining line is $\frac{-7-(-11)}{-2-(-4)} =2$

B. The points are (5,6) and (-5,12).

Then the slope of the joining line is $\frac{12-6}{-5-5} =-\frac{3}{5}$

C. The points are (0,-3) and (-4,-11).

Then the slope of the joining line is $\frac{-11-(-3)}{-4-0} =2$

D. The points are (0,-3) and (5,7).

Then the slope of the joining line is $\frac{7-(-3)}{5-0} =2$

Therefore, options A, C, D are true. (Answer)

400 grams = 480 ml<br> so,<br> 180 grams = ?

Viefleur [7K]

Answer: 216 ml

Step-by-step explanation:

400 grams = 480 ml

180 grams = ?

Since the value of 180 grams in milliliters is unknown, let the unknown be Z

Thus, 400 grams = 480 ml

180 grams = Z

To get the value of Z, cross multiply

Then, Z x 400 grams = 480ml x 180 grams

400Z = 86400

Divide both sides by 400

400Z/400 = 86400/400

Z = 216

Thus, 180 grams is equal to 216 milliliters.

Complete the sentence

ryzh [129]

Answer: b, d

Step-by-step explanation:

Corresponding angles are formed when two parallel straight lines are cut by a transversal

$\angle b=62^{\circ}$

In the figure, $\angle d\ \text{and}\ 62^{\circ}$ are alternate angle

$\therefore \angle d=62^{\circ}$

I need help with this please

Nookie1986 [14]

Answer:

steps below

Step-by-step explanation:

3.2.1 AD = DB* sin 2 = DB * sin θ .. DE // AB ∠2= θ ... (1)

By laws of sines: DB / sin ∠5 = x / sin ∠4

∠4 = θ-α ∠5 = 180°-<u>∠1</u>-∠4 = 180°-<u>∠3</u>-∠4 = 180°-(90°-θ)-(θ-α)) = 90°+α

DB = (x*sin ∠5)/sin (θ-α)

= (x* sin (90°+α)) / sin (θ-α)

AD = DB*sinθ

= (x* sin (90°+α))*sinθ / sin (θ-α)

= x* (sin90°cosα+cos90°sinα)*sinθ / sin (θ-α) .... sin90°=1, cos90°=0

= x* cosα* sinθ / sin (θ-α)

3.2.2 Please apply Laws of sines to calculate the length
