Answer:

Step-by-step explanation:

To find volume you have to use the formula (length x width x height.)

So by looking at it you can see that it's 3 units long, 3 units in wide, and 2 units tall. Knowing that, you then plug in those numbers to the formula. That would be 3x3x2. Any calculator will work.

Answer: 224 ounces are in 14 pounds

Step-by-step explanation:

1 pound = 16 ounces

*14            *14

14 pounds = 224 ounces

Answer: x = 5

Step-by-step explanation:

We can set up an equation to solve for x:

3x  + 4 = 19

We can subtract 4 from both sides:

3x = 15

We can divide both sides by 3:

x = 5

Answer:

the square root of 55, or 7.42

Step-by-step explanation:

Use the Pythagorean Theorem, or  a²+b²=c², where a and b are the sides or "legs" of the triangle and c is the hypotenuse.

a is 3, b is x, and c is 9

If you plug that into the equation, you get 3²+x²=8²

We can make this 9+x=64 by squaring the 3 and 8.

Then we can subtract 9 from each side to get x=55.

Finally, take the square root of 55 to get √55 or 7.42.

Answer:

x = 45

(2x-10) = 80

x+10 = 55

Step-by-step explanation:

so, make an equation to find x:

x+2x-10+x+10 = 180

collect like terms

4x = 180 (divide both sides by 4)

x = 45

sub into the formulas:

x- 10 = 45+10 = 55

2 × 45 - 10 = 80

add them together to see if it is correct:

45 + 55 + 80 = 180

Answer:

Now, let x equal the number:

10 times the number is 10x.

Sum of 10 times the number and 15, means sum of 10 times the number plus 15, which is 10x + 15.

Eleven times the same number, means 11 times x, which is 11x.

Sum of 10 times a number and fifteen is added to eleven times the same number is therefore: 10x + 15 + 11x = 21x + 15

Answer:

Step-by-step explanation:

Perimeter of a square = 4 * Length of the square

Given

Length of a square = 4y + 7

Perimeter of the square = 4(4y+7)

Open the parenthesis

Perimeter of the square = 4(4y)+4(7)

Perimeter of the square = 16y + 28

Hence the perimeter of the square is 16y+28

To save 6 months’ worth of your fixed expenses in an emergency fund will take approximately 5 months.

An emergency fund is a safety net used specifically to cover basic living expenses for at least 6 months in case future mishaps or unexpected expenses arise.

Financial experts generally recommend six months of basic living (fixed) expenses to put away in an emergency fund.

The amount to save in the emergency fund = $3,753.79 ($2,085.44 x 30% x 6)

50% of discretionary monies = $729.90 ($2,085.44 x 1 - 30%) x 50%

Months to save $3,753.79 saving $729.90 = 5 months ($3,753.79/$729.90)

Your realized income is $2,085.44, and your fixed expenses are 30%. You want to save 6 months’ worth in an emergency fund.

How many months will it take to fully fund it, excluding interest accrual?

Thus, o save 6 months’ worth of your fixed expenses in an emergency fund will take approximately 5 months.

Answer:

To calculate this, we first need to find the amount of discretionary money left after paying fixed expenses:

Discretionary money = Realized income - (Fixed expenses as a percentage of realized income)

Discretionary money = $2,085.44 - (30% x $2,085.44)

Discretionary money = $2,085.44 - $625.63

Discretionary money = $1,459.81

We want to put 50% of this toward the emergency fund each month, so:

Emergency fund contribution per month = 50% x $1,459.81

Emergency fund contribution per month = $729.91

To find out how many months it will take to fully fund the emergency fund, we divide the total amount needed by the monthly contribution:

Number of months = (Total amount needed) / (Emergency fund contribution per month)

Number of months = $18,292.65 / $729.91

Number of months = 25.06

Rounded up to the nearest whole month, it will take 26 months to fully fund the emergency fund.

Therefore, the answer is:

26 months
