Alexander is a stockbroker. He earns 14% commission each week. Last week, he sold $5,400 worth of stocks. How much did he make

Vlada [557]

Answer:

In that one week, his commision was $896, over all 52 weeks, he made $46592

Step-by-step explanation:

So, he makes 14% commision on any stock he sells. This week, he sold $6,400 worth of stocks, and, hes going to make 14% on it. So, take 6400 and divide that by 14%, and what do you get? $896! So, he made $896 that week. Now, say he made that amount EVERY WEEK. so, all you have to do is know how many weeks are in a year (52) and multiply that by 896, which gives you 46592.

The gas tank in Sharon’s car can hold up to 16.5 gal of gas. About how many liters of gas can the tank hold? 1 L≈1.06 qt

Andreas93 [3]

we know that

a) $1$ gallon is equal to $4$ quarter of gallon

so

by proportion

$16.5$ gallons is equal to

$\frac{1}{4} =\frac{16.5}{x} \\ x=16.5*4\\ x=66$ quarter of gallon

b) $1$ liter is equal to $1.06$ quarter of gallon

by proportion

$66$ quarter of gallon is equal to

$\frac{1}{1.06} =\frac{x}{66} \\ x=\frac{66}{1.06} \\ x=62.26\\ x=62.3$ liters

therefore

the answer is the option

$62.3L$

Tom has 120 meters of fencing. He will use it to form three sides of a rectangular garden. The fourth side will be along a house

mezya [45]

Answer:

a) Function A(x) = (60*x - 1/2*x²)

b)Side length x = 60 m the other side y = 30 m

c) A (max) = 1800 m²

Step-by-step explanation:

Area of rectangular garden with length " x " and wide "y"

A = x*y

Perimeter of rectangular area ( only three sides 2*y and 1*x)

P(r) = 2*y + x

P(r) = 120 = 2*y + x

y = ( 120 - x ) /2

Area of the garden as function of x is

A(x) = [( 120 - x ) /2]*x ⇒ A(x) = (60*x - 1/2*x²)

Taking derivatives on both sides of the equation:

A´(x) = 60 - x

A´(x) = 0 60 - x = 0

x = 60 m

Then

y = ( 120 - x ) / 2 ⇒ y = (120 - 60 )/2

y = 30 m

A(max) = 30 * 60

A(max) = 1800 m²

1. The number of gallons of water produced is 460 gallons

2. The amount in cm the sea would increase after 6 years is 392 cm

<h3>1. How to determine the number of gallons produced</h3>

We'll begin by by converting 1.9 m³ to cm³. This is illustrated below:

1 m³ = 1×10⁶ cm³

Therefore,

1.9 m³ = 1.9×10⁶ cm³

Next, we shall determine the volume of water produced from 1.9 m³ (i.e 1.9×10⁶ cm³) of ice. This is illustrated below:

From the question given,

1 cm³ of ice = 0.92 cm³ of water

Therefore,

1.9×10⁶ cm³ of ice = 1.9×10⁶ × 0.92

1.9×10⁶ cm³ of ice = 1.748×10⁶ cm³ of water

Finally, we shall determine the number of gallons produced. This is illustrated below:

From the question given,

3800 cm³ of water = 1 gallon

Therefore,

1.748×10⁶ cm³ of water = 1.748×10⁶ / 3800

1.748×10⁶ cm³ of water = 460 gallon

Thus, 460 gallons were produced

<h3>2. How to determine the amount in cm the sea would increase to after 6 years</h3>

From the question given above,

1000 Km³ = 364 cm

Therefore,

179.4 Km³ = (179.4 × 364) / 1000

179.4 Km³ = 65.3016 cm per year

To obtain the increase after 6 years, multiply 65.3016 by 6 as shown below:

65.3016 × 6 = 392 cm

Thus, the sea will increase 392 cm after 6 years
