Answer:

3 Feet

Step-by-step explanation:

Issac's Kitchen Area - 54 sqft

Issac's Pantry Area - 54/9 = 6 sqft (His pantry is 9x smaller than his kitchen)

[tex]area = length * width[/tex]

Here we have the total area and the width, so we can substitute for finding the length:

[tex]6 = length * 2\\ \\ = > \frac{6}{2} = length\\ \\ = > length = 3[/tex]

Hence is pantry is 3 feet long.

Answer:

first one (2*2*2*3*3)

Step-by-step explanation:

2*2*2*3*3=72

Considering that a transversal line cuts two parallel lines, the relations between the angles are given as follows:

1. Corresponding angles.

2. Alternate exterior angles.

3. Consecutive interior angles.

Angles 1 and 3 are corresponding angles, as they are both at the same position relative to their lines, j for angle 1 and m for angle 3, being cut by the transversal line t.

Angles 4 and 8 are alternate exterior angles, as:

Inverse positions in both senses, left/right and up/down, hence alternate exterior angles.

Angles 2 and 3 form a supplementary pair inside the same region, between the two lines being cut by the transversal, hence they are consecutive interior angles.

It should be no mystery that amounts deposited get added to bank balance, and amounts withdrawn by any means get subtracted. Regarding the balance in the bank, a debit card withdrawal is equivalent to a cheque withdrawal.

Regarding the balance in the bank, a debit card withdrawal is equivalent to a cheque withdrawal. The debit card withdrawal differs from a check in the check register in that there is no check number (and frequently no transaction number) connected to it.

initial transaction

$100 is deposited to open the account. The starting balance is that sum.

two-way transaction

You must calculate the tax on the purchases for this issue. Normally, the store would take care of that for you, and you would write a check to cover the debt. The sum owed in this case is...

Rounding up from $43.82 to 45.5728 is 45.57.

Instead of calculating the tax individually and then adding it to the original amount, it is more convenient to use a multiplier to determine the amount with tax. You should be aware that the purchase price multiplied by 100% plus 4% equals 104%, or 1.04 times the price.

As a withdrawal, this $45.57 is deducted from the prior transaction's $100 total, resulting in a new balance of $54.43.

third action

This is a straightforward withdrawal, therefore $46.43 is obtained by deducting the sum from the prior balance.

As previously said, there is no transaction number connected to this. It can occasionally be helpful to keep track of which debit card is being used if you have several debit cards that are taking money out of the account. The final four digits of the card number are used to identify transactions on my bank statement.

Fourth action

You must calculate the payroll deposit amount for this problem. That would typically be handled for you by your employer, along with any deductions for taxes, insurance, union dues, or employee purchases. The sum deposited in this case is...

Hourly rate times 40 equals $9.75, which equals $390.

The previous value is increased by this deposit, making the new balance $436.43.

In most cases, the coupon is applied to transactions including coupons before the tax is calculated. The fact that the purchase amounts are combined should be obvious. (You can calculate the total when there are numerous items at the same price using repeated addition or multiplication; most people find multiplication to be simpler.)

The purchase from the bike shop is arguably the most difficult. The total of the values in brackets is...

$180.00 + 14.95 + 8.95 = 203.90

Then, the 15% discount is applied.

Rounding up to 30.59 from 0.15 x $203.90 = 30.585

Taking this out of the previous amount* yields (before taxes)...

$203.90 -30.59 = $173.31

The amount subject to tax can then be calculated using the same multiplier described above:

Round to $180.24 using the formula: amount with tax = $173.31 x 1.04 = $180.24

* Talk about the 15% discount

As with additional tax, you can calculate the discount using a multiplier:

100% - 15% = 85% . . . 0.85 times as much

The result of applying this multiplier to the number 203.90 is 173.315, which is typically rounded up to 173.32. But this figure results from a discount that is rounded to the nearest half cent (30.585). The discounted amount, 173.315, is rounded down to 173.31 if the discount is rounded up. The intricacy of applying a multiplier to discounts is there.

Step-by-step explanation:The walker family uses 45 pounds of crisped rice cereal per year. 1.55 pounds  they save by buying the 18-oz. box for $3.50 rather than the 12-oz. box for $2.75  by using unitary method.

What is called pound?

A pound is a unit of weight used mainly in Britain, America, and other countries where English is spoken. One pound is equal to around 0.454 kilograms. A pound of something is a quantity of it that weighs one pound.

For this, we get the unit price per ounce of each.

3.50/ 18 = 0.1944 unit

2.75 / 12 = 0.229 unit

The walker family uses 45 pounds of crisped rice cereal per year 45 ×0.1944=8.74845 ×0.229= 10.305.

Thus ,they save 10.305 - 8.75 = 1.55

Answer:

56.4 degrees

Step-by-step explanation:

You can make a right-angle triangle from the isosceles triangle, with height 2.5cm and hypotenuse 3cm.

You have the opposite side to the angle and the hypotenuse, so you use sin x = Opposite/Hypotenuse

sin x = 2.5/3

x = [tex]sin^{-1}[/tex] (2.5/3)

x = 56.44269024

Therefore the base angle of the triangle is 56.4 degrees (3sf)

86 = 1p + 5n

n = p + 4

86 = 1p + 5(p + 4)

86 = 1p + 5p + 20

66 = 6p; p = 11

86 = 1(11) + 5n

86 = 11 + 5n

75 = 5n; 15 = n

11 pennies, 15 nickels

11(1) + 15(15) = 11 + 75 = 86

In order to solve this quadratic equation by completing the square, let's analyse the coefficient b by comparing the equation with the standard form:

We have b = -12. In order to be a perfect square, the coefficient c needs to be (-12/2)^2 = (-6)^2 = 36

We already have 30, so we just need to add 6:

Answer:

2.4

Step-by-step explanation:

tan(theta) is defined as: [tex]tan(\theta)=\frac{\text{opposite}}{\text{adjacent}}[/tex]

in the given diagram we only have the opposite and hypotenuse, but we can use the Pythagorean Theorem to solve for the other two missing sides.

Pythagorean Theorem: [tex]a^2+b^2=c^2[/tex], where c is the hypotenuse.

Plugging in known values we get the following:

[tex]a^2+12^2=13^2[/tex]

in this case the missing side, or the adjacent side is simply "a"

from here we simplify the bases with exponents

[tex]a^2+144=169[/tex]

now subtract 144 from both sides

[tex]a^2=25[/tex]

take the square root of both sides

[tex]a=5[/tex]

So now we know the adjacent side so we can plug it into the tan equation

Based on the given parameters, the amount of the investment after 4 years is $1030

The given parameters about the compound interest are

Principal Amount, P = $1000

Interest Rate, R = 0.85%

Time, t = 4

Number of times, n = 1 i.e. annually

Compound interests are different from simple interest, and they are calculated using the following compound interest formula

CI = P(1 + R/n)^nt - P

To calculate the amount, we have:

A = P + CI

So, the equation becomes

A = P + P(1 + R/n)^nt - P

Evaluate the like terms

A = P(1 + R/n)^nt

Substitute the known values in the above equation

A = 1000 * (1 + 0.85%/1)^(1 * 4)

Express 0.85% as decimal

A = 1000 * (1 + 0.0085/1)^(1 * 4)

Evaluate the sum

A = 1000 * (1.0085/1)^(1 * 4)

Evaluate the exponent

A = 1000 * 1.03

Evaluate the product

A = 1030

Hence, the value of the investment is $1030

If  x and y vary directly, than the relationship between y and x will be →

y = (16/9)x

Direct proportion or direct variation is the relation between two quantities where the ratio of the two is equal to a constant value.

Given is x and y vary directly and y = 32 when x = 18.

Since x and y vary directly, this means that -

y/x = K [constant]

Now, we have -

x = 18

y = 32

Substituting values -

32/18 = K

K = 32/18 = 16/9

y/x = 16/9

y = (16/9)x

Therefore, if  x and y vary directly, than the relationship between y and x will be → y = (16/9)x

The linear equation that models the water left in the bathtub is g = 32 - 4t.

The first step is to determine the rate of drainage of the bathtub. The rate of drainage is the ratio of the change in water to the change in time.

Rate of drainage = change in water levels in the bathtub / change in time

(20 - 36) / (7 - 3)

-16 / 4 = -4

The second step is to determine the amount of water in the bathtub before it started draining

Initial amount of water in the bathtub = 20 + (4 x 3) = 32 gallons

The form of the linear equation that can be used to determine the amount of water left in the tank is:

Water in the bathtub = initial amount of water - (rate of drainage x number of minutes)

g = 32 - 4t
