Answer: $there \ are \ 28 \ members \n the \ number \ of \ members \ renting \ skis - x\nthe \ number \ of \ members \ renting \ snowboards - y\nskis \ rent \ for \ \$16.00 \ a \ day \ and \ snowboards \ rent \ for \ \$19.00 \ a \ day\n\n\begin{cases} x+y=28 \ \ / \cdot (-16) \n 16x+19y = 478 \end{cases}$

$\begin{cases} -16x-16y=-448 \n 16x+19y = 478 \end{cases}\n+ -------\n3y=30 \ \ / :3 \ny=10 \n \n x+y=28\nx+10=28\nx=28-10\nx=18 \n \n Answer: \ 18 \ members \ rented \ skis .$

Answer 2

Answer:

Answer:

16 skis and 18 snowboards were rented.

Step-by-step explanation:

Let the number of skis rented be and the number of snowboards rented be .

If a total of people rented on a certain day, then the total number of skis and snowboards rented that particular day is also .

This gives us the equation

If skis cost $ , then number of skis cost $ .

If snowboards cost $ , then number of snowboards cost $ .

The total cost will give us another equation,

From equation (1),

We put equation (3) into equation (2) to get,

We expand the brackets to obtain,

We group like terms to get,

This implies that,

We divide both sides by to get,

We put into equation (3) to get,

Therefore skis and snowboards were rented.

Answers

Answer:

let x is the smaller number

bigger number is x + 8

The sum of two numbers is 72

x + (x+8) = 72

answer

x + (x + 8) = 72

Step-by-step explanation:

Answer:

Step-by-step explanation:

Two numbers add up to 72

let's assume they r x and y

ome number is 8 more than the other

so it will be xand x+8

Therefore x+x+8=72

Here is a mantra that I learned in Geometry class in high school. We were
all very excited, as angles had been invented only a few years earlier:

In a 30-60 right triangle ...
the side opposite the 30 is half the hypotenuse
the side opposite the 60 is half the hypotenuse times the square root of three.

So the tangent of the 30 would be (opposite) / (adjacent) = (1/2h) / (1/2h√3) .

That's (1)/(√3) or (√3)/(3) .

$Look\ at\ the\ picture.\n\ntan30^o=((a)/(2))/((a\sqrt3)/(2))=(a)/(2):(a\sqrt3)/(2)=(a)/(2)\cdot(2)/(a\sqrt3)=(1)/(\sqrt3)\cdot(\sqrt3)/(\sqrt3)=(\sqrt3)/(3)$

Chang industries has bonds outstanding with a par value of $212,000 and a carrying value of $221,000. if the company calls these bonds at a price of $216,000, the gain or loss on retirement is:

Answers

Answer:

The gain on retirement is $5,000

Step-by-step explanation:

In this question, we are asked to calculate the gain or loss on retirement if a company calls some bonds at a particular price.

From the question, we can identify the following needed parameters to solve the question;

The carrying value of bonds = $221,000

Call price of bonds = $216,000

Mathematically, the gain on retirement can be calculated as follows;

Gain on retirement = carrying value - call price

= $221,000 - $216,000 = $5,000

Hence , the gain on retirement is $5,000
