Tresset [83]3 years ago

Answer:

Step-by-step explanation:

No. When you cross multiply the numbers should be equal.

So (3)(18) = (4)(24) but they are not equal so it is not a proportion

8. Mitchell bought 600 shares of Centerco two years ago $34.50 per share. He sold them yesterday for $38.64 per share.

g100num [7]

Answer:

a. percentage increase in price per share = 12%

b. The total purchase price for the 600 shares is $20,700

c. The profit for the 600 shares is $2,484

d. The profit for the 600 shares is $2,484

Step-by-step explanation:

a. Initial price per share = $34.50

Current price per share = $38.64

Change or increase in price = $38.64 - $34.50 = $4.14

percentage increase in price per share = 12/34.50 x 100% = 12%

b. Total number of shares = 600

Price = $34.50

The total purchase price for the 600 shares = ($34.5x600) = $20,700

c. Total cost of 600 shares = ($34.5x600) = $20,700

Total revenue from sales = ($38.64x600) = $23,184

Profit from the 600 shares = Total selling price - total cost price

= $23,184 - $20,700 = $2,484

d. Total cost of 600 shares = ($34.5x600) = $20,700

Total revenue from sales = ($38.64x600) = $23,184

Profit from the 600 shares = Total selling price - total cost price

= $23,184 - $20,700 = $2,484

Solve for x b=1/6π n ^2 x

Setler [38]

Answer:

$\large\boxed{x=\dfrac{6b}{\pi n^2}}$

Step-by-step explanation:

$b=\dfrac{1}{6}\pi n^2x\qquad\text{multiply both sides by 6}\\\\6b=\pi n^2x\qquad\text{divide both sides by}\ \pi n^2\neq0\\\\\dfrac{6b}{\pi n^2}=b$

Karen has 1/2 cup of sugar. She is baking cookies and needs 1 1/3 cups for a recipe. How much more sugar does she need If she wa

Evgen [1.6K]

Answer:

3 1/2 cups

Step-by-step explanation:

Let's start by figuring out how much sugar Karen needs in total.

She needs (1+1/3) cups for her original recipe. To triple that, we need (1+1/3) 3 times. We can calculate this by multiplying it by 3.

(1+1/3) * 3 = 3 + 1 = 4

Karen needs 4 cups in total. She has 1/2 cup. The difference is how much more she needs. Therefore, she needs 4 - 1/2 = 3 1/2 cups

Example:

Aleonysh [2.5K]

Answer:

AB // CD and AD // BC, then ABCD is a parallelogram

Step-by-step explanation:

Step 2: Show AD // BC

A = (-3 , 3) and D = (0 , 0)

Find the slope of AD

$m_{AD}=\frac{0-3}{0--3}=\frac{-3}{3}=-1$

B = (2 , 5) and C = (5 , 2)

$m_{BC}=\frac{2-5}{5-2}=\frac{-3}{3}=-1$

The slope of AD = the slope of BC

So AD // BC because they have the same slope

Step 3:

Each two opposite sides are parallel in quadrilateral ABCD

So the quadrilateral is a parallelogram
