Please help. I am stuck on this algebra question:
A homeowner wants to increase the size of his deck that now measures 15 feet by 18 feet. His homeowner's association declares that no deck is to be more than 928 square feet. if the length and the width of the deck are to be increased by the same amount, find, TO THE NEAREST TENTH, the maximum number of feet by which the length of the deck may be legally increased.

a) 14 feet
b)21 feet
c)28 feet
d)32 feet

Answers

Answer 1
Right now the deck (rectangle) is 15 feet (l) by 18 feet (w).
The area is not allowed to be more than 928 square feet.

A ≤ 928
The area of a rectangle = lw
lw ≤ 928

The variable 'x' will be the max number of feet the deck can be increased.
(x + 15)(x + 18) ≤ 928

Use FOIL to solve this.
First- (x)(x)
Outer- (x)(18)
Inner- (15)(x)
Last- (15)(18)

x² + 18x + 15x + 270 ≤ 928
x² + 33x + 270 ≤ 928

Now you can either factor or do the quadratic formula.
 x² + 33x - 658 ≤ 0
(x + 47)(x - 14) ≤ 0
x = -47 ; x = 14

-47 ≤ x ≤ 14

So the number has to be greater than/equal to -47 or less than/equal to 14.

The answer is 
A) 14 feet.

How to simplify 6/18

Answers

The numerator (12) and the denominator (18) are both divisible by 6 (so the largest number that goes exactly into both 12 and 18 is 6 and therefore the greatest common factor is 6). Therefore if you divide the numerator and denominator by 6, you can write the fraction as (12/6)/(18/6) = 2/3.

The simplified form of [tex]\frac{6}{18}[/tex] is [tex]\frac{1}{3}[/tex].

To simplify the fraction [tex]\frac{6}{18}[/tex], follow these steps:

Find the greatest common divisor (GCD) of the numerator and the denominator. The numerator is 6 and the denominator is 18. The greatest common divisor of 6 and 18 is 6.

Divide both the numerator and the denominator by their GCD.

When we divide the numerator 6 by 6, we get [tex]\frac{6}{6} = 1[/tex].

When we divide the denominator 18 by 6, we get [tex]\frac{18}{6} = 3[/tex].

Write the simplified fraction: After dividing both parts by 6, the fraction [tex]\frac{6}{18}[/tex] simplifies to [tex]\frac{1}{3}[/tex].



Write the fraction 8/9=as an equivalent fraction with the given denominator 18

Answers

16/18, which is 8/9 reduced
Final answer:

The equivalent fraction of 8/9 with the denominator 18 is 16/18.

Explanation:

To write the fraction 8/9 as an equivalent fraction with the given denominator 18, we have to find a number that we multiply by 9 (the original denominator) to get 18. This number, in this case, is 2. What we do to the bottom of a fraction, we should also do to the top, therefore we would also multiply the numerator (8) by the same number (2). So, the equivalent fraction is 8 * 2 / 9 * 2 = 16 / 18.

Is every isosceles triangle equilateral? Is every equilateral triangle isosceles? Explain

Answers

Every equilateral triangle is also anisosceles triangle, so any two sides that are equal have equal opposite angles. Therefore, since all three sides of an equilateral triangle are equal, all three angles are equal, too.
Hello There!

Not every isosceles triangle is equilateral.
This is because they don't always have equal angles.
The definition of an equilateral triangle is a triangle with all equal angles.
However, every equilateral is an isosceles.
This is because it would have at least 2 sides of equal length.
The definition if an isosceles triangle is a triangle with at least two equal side lengths.

The change in the value of an account when given to the nearest dollar

Answers

The net change in the value of the account, when rounded to the nearest dollar, is $550.

To find the net change in the value of the account, you would sum up the amounts deposited, subtract the amounts withdrawn, and add the interest earned:

Net change = (Deposits - Withdrawals) + Interest earne

Net change = ($500 - $250) + $300

            = $250 + $300

            = $550

Therefore, the net change in the value of the account, when rounded to the nearest dollar, is $550.

The probable question maybe:

"What is the net change in the value of an investment account after depositing $500, withdrawing $250, and earning $300 in interest, when rounded to the nearest dollar?"

I want to say it's 84 combined because two roller coaters can hold 14 so seperately it's 7. 7x12=84 so I believe the answer is 84. I'm sorry if it's wrong.

The rate of riders to cars is 14 divided by 2. So the unit rate is 7 riders per car. Multiply 7 riders by 12 cars to find that 84 riders can fit on the roller coaster at one time.

Jillian is selling boxes of cookies to raise money for her basketball team. The 10 oz. box costs $3.50, while the 16 oz. box costs $5.00. At the end of one week, she collected $97.50, selling a total of 24 boxes. The system of equations that models her sales is below. x+ y= 24 3.50x + 5.00y = 97.50 Solve the system of equations. How many 10 oz. boxes were sold?

Answers

The answer would be 15 boxes!

Answer:

There are 15 boxes of 10 oz boxes

Step-by-step explanation:

Let the number of boxes of 10 oz = x

and let the number of boxes of 16 oz = y

By the statement

"Total number of boxes sold is 24"

Equation for the statement will be

x + y =24 ---------------(1)

By the  statement

"she collected $97.50 while rate of 10 oz box is $3.50 and rate of 16 oz box is $5.00."

Equation for the statement will be

1.5x + 5y = $97.50 ------------(2)

From equation (1) we put the value of y = 24 - x in equation (2)

1.5x + 5(24 - x) =  97.50

1.5x + 120 - 5x = 97.50

-3.5x = 97.50 - 120

3.5x = 22.50

x = [tex]\frac{22.5}{1.5}[/tex]

x = 15

Therefore, number of 10 oz boxes is 15.

Answers

Given that the mass of the sun is 2.13525×1030 kilograms, and the mass of Mercury to be 3.285×1023 kilograms. We determine how many times greater the mass of the sun is relative to the mass of Mercury by getting the ratio of their respective masses. With this, we compute the ratio to be 2.13525×1030/3.285×1023 which is equal to 6500000. With this calculation, we can infer that the mass of the sun is 6.5x106 times greater than the mass of mercury.

We have been given that a helicopter is flying at a altitude of 785 feet, this means that altitude of helicopter is positive.

Further, the helicopter descends 570 feet, this means that altitude of helicopter is [tex]-570[/tex].

Finally, the helicopter ascends 595 feet, this means that altitude of helicopter is [tex]595[/tex].

[tex]\text{Helicopter's final elevation}=785\text{ ft}-570\text{ ft}+595\text{ ft}[/tex]

[tex]\text{Helicopter's final elevation}=810\text{ ft}[/tex]
