8 0

$\text {Volume =} \dfrac{1}{3} \pi r^{2} h$

$\text {Volume =} \dfrac{1}{3} \pi (6)^{2} (9)$

$\text {Volume =} 339.29 \ yd^3$

the area of a triangle is 6 and 3/8 square yards. The height of the triangle is 2 and 1/2 yards. What is the length of the base

Otrada [13]

Solution:

Note that:

Area of triangle = 6 3/8 yd²
Height of triangle = 2 1/2
Area of triangle = 1/2 x base x altitude

Use the formula to find the base of the triangle.

1/2 x base x altitude = 6 3/8 yd²
=> 1/2 x base x 2 1/2 = 6 3/8 yd²
=> 1/2 x base x 5/2 = 6 3/8 yd²
=> 5/4 x base = 6 3/8 yd²
=> base = 6 3/8 ÷ 5/4 yd
=> base = 51/8 x 4/5 yd
=> base = 51/2 x 1/5 yd
=> base = 51/10 yd

The length of the base is 51/10 yards.

F (x) = |x + 3| -1 . Find the average rate of change from x = -6 to x = 8

Elenna [48]

Average rate of change is (f(8) - f(-6))/(8 - (-6)) = ((|8 + 3| -1) - (|-6 + 3| -1))/(8 + 6) = ((|11| -1) - (|-3| -1))/14 = ((11 - 1) - (3 - 1))/14 = (10 - 2)/14 = 8/14 = 4/7

Fill in the missing numbers along the sides of the triangle so that it contains each of the numbers from 4 through 12 exactly on

elixir [45]

Answer: A B == 9 + 11 CD == 5 +7 E F == 6 + 10

Step-by-step explanation:

(This reminds me of a "formula" I developed a few years ago when I was photographing formal groups, and had to figyre out how many people to put in each row, and the rows had to be different lengths) Anyway--

Get the sum of the numbers at the angles, subtract that number from 32, and that's the amount needed for the row.

Once I have that number, divide by 2 and split as "n + 1 and n-1

AB side: angles given: 8 +4=12 , 32-12 =20 20/2 = 10; 10+1 =11 10-1=9

CD side: angles given: 8 + 12 =20, 32-20=12; 12/2 =6 6+1 =7 6-1 =5

EF side: angles given: 4 + 12 =16 32-16=16 My formula would have yielded 7+9, but those numbers were already used. Conveniently, 10 + 6 are left over. Same principle, but + or - 2.

Thanks for the opportunity to work in this!
