a rectangle is 12 feet longer than it is wide. Find the dimensions of the rectangle if the area is 220 sq ft

Answers

Width - x

Length - (x+12)

Area - x(x+12)

x(x+12)=220

x²+12x-220=0     -220 =22*(-10), 12=22-10

(x+22)(x-10)=0

x=-22, x=10

For width, we can use the only positive number,

so, the width is 10 feet.

Length is 10+12=22 feet.

A drawer contains 30 pens of various colors: 4 are black, 10 are blue, 3 are red, 6 are green, 6 are blue and red, and 1 is white. A white pen is removed from the drawer.

Answers

Answer:

the probability in the case when the white pen would be removed from the drawer is 1 ÷ 30

Step-by-step explanation:

The computation of the probability in the case when the white pen would be removed from the drawer is given below

= Favorable outcome ÷ total outcome

= 1 ÷ 30

Hence, the probability in the case when the white pen would be removed from the drawer is 1 ÷ 30

The present price of a motorcycle is
Rs. 2,25,000. If its price is depreciated per year by 8 %, after
how many years will be the price of the motorcycle be
Rs. 1,75,204.80 ? Find it.​

Answers

Answer:

3.25 years

Step-by-step explanation:

The computation of the number of years is shown below:

Given that

PV = $225,000

RATE = 8%

PMT = $0

FV = $175,204.80

The formula is shown below:

= NPER(RATE;PMT;PV;FV;TYPE)

After applying the above formula, the number of years would be 3.25 years

The same would be considered

One way to divide decimal numbers is to use an equivalent expression.

Complete the statements below to explain one way to find 8.4 ÷ 2.1.

Answers

Answer:

104

Step-by-step explanation:

To determine how much a decimal was multiplied, you need to find how many places the decimal moved.

In this case we can see the decimal moved once. How many times the decimal moved can be represented by the zeros in the number. So 10 = 1

100 = 2     1,000 = 3 and it keeps going.

So since the decimal moved 1 time, the answer to question one is 10

Now question 2.

Both 8.4 ÷ 2.1 and 84 ÷ 21 will give the exact same answer. It is just easier to solve. So solve which one is easier for you. I did 84 ÷ 21.

84 ÷ 21 = 4

We can verify our answer by multiplying the the divisor by the quotient

21 * 4 = 84

So 4 is the answer to question 2

A shirt priced at x dollars is discounted before tax is added. The final
price in dollars is described by the expression below.
1.05(x-0.6x)
What is the sales tax for the shirt?

Answers

Answer:

not sure if that is right

The sales tax for the shirt is 0.05(0.4x).

What is the sales tax?

Calculating the sales tax applied to a purchase is a matter of simply multiplying the tax rate by the purchase price using the equation sales tax = purchase price × sales tax rate. Adding the sales tax to the original purchase price gives the total price paid with tax.

Given that, a shirt priced at x dollars is discounted before tax is added.

In the final price, (x-0.6x) represents the discount of 60% on the shirt.

After that sales tax was applied which was 1.05 ≈ 105%. So, the sales tax is 5%

Then the sales tax is

5% × (x - 0.6x)

5% × (0.4x)

0.05(0.4x)

Therefore, the sales tax for the shirt is 0.05(0.4x).

Answers

Answer:

may be A?? i dont really know bt i think A

Answer: B

Step-by-step explanation:

First, let's take the point of the origin so (0,0).

Let's substitute it back into the equations:

0 is x, 0 is y

A: 0> -1 true

B: 0 ≥ -1 also true

C: 0 < -1 not true

D: 0 ≤ -1 not true

So now, for C and D the region containing the (0,0) is the unwanted region (shaded) because the inequality is not true.

However, the graph has the side with point (0,0) unshaded.

So we know that the answer is A or B.

In linear programming signs <> are expressed as dotted lines and ≤≥ as unbroken lines.

The graph has an unbroken line so answer B is correct as it has the sign ≥ (representing an unbroken line) and satisfies the inequality.

Kianas soccer teams ratio of wins to losses is 5:3. Her team has played 24 games how many games have they won? 

Answers

Given:

Kianas soccer teams ratio of wins to losses is 5:3.

Her team has played 24 games.

To find:

The number of games they won.

Solution:

Let the number of games they won be 5x and the number of games they lost be 3x.

Total number of games is 24.

[tex]5x+3x=24[/tex]

[tex]8x=24[/tex]

[tex]x=\dfrac{24}{8}[/tex]

[tex]x=3[/tex]

Now, the number of games they won is:

Number of games they won = [tex]5x[/tex]

                                               = [tex]5(3)[/tex]

                                               = [tex]15[/tex]

Therefore, they won 15 games.
