You need to have at least $100 in your checking account to avoid a low balance fee. You have $247 in your account, and you make withdrawals of $20 per week. What are the possible numbers of weeks that you can avoid paying the fee? Solve this problem using two different methods. PLEASE HELP
7 WEEKS is how long you can last.
First off, you need at least $100 in your account to avoid the fee and you currently have $247. With that being said, you're taking out $20 every week.
The first thing you can do would be to start at $147 (since that's $100 less than what you can use) and divide that by 20 (since that's what you're taking out every week) 147 / 20 = 7.35. That's 7 weeks because you have to round down to the nearest whole number.
Second What you can do to find how many weeks you can take this out by starting at $100 and adding $20 for every week. So 120, 140, 160, 180, 200, 220, 240. This also gives you 7.
You can take $20 out of your account for 7 WEEKS until you have to pay the low-balance fee.

Jenny's Bakery sells carrot muffins for $2.00 each. The electricity to run the oven is $120.00 per day and the cost of making one carrot muffin is $1.40. How many muffins need to be sold each day for the bakery to break even?
Answer:
D. 200 muffins
Step-by-step explanation:
Break even is a condition where the total production cost is same as the profit produced. In this question, the carrot muffin cost is $1.4 and sold at $2. Then the profit for every muffin should be: $2- $1.4= $0.6/muffin
The electricity cost is $120/day. Then to cover this cost, the muffin need to sold would be:
cost= muffin profit * muffin sold
$120= $0.6/muffin * muffin sold
muffin sold= $120 / ($0.6 / muffin)= 200 muffin

if sin theta =1/4, theta in quadrant II, find the exact value of cos[theta +pi/6]
The exact value of cos(θ + π/6) when sin θ = 1/4 and θ is in quadrant II is (-√(45) - 1)/8, found by using the Pythagorean identity and the angle sum identity.
To find the exact value of cos(θ + π/6) when sin θ = 1/4 and θ is in quadrant II, we can use trigonometric identities and properties of angles. First, we use the Pythagorean identity to find cos θ. Since θ is in the second quadrant, cos θ is negative and solving for cos θ gives cos θ = -√(1 - sin² θ) = -√(1 - (1/4)²) = -√(15)/4.
Next, we apply the angle sum identity for cosine, which is cos(α + β) = cos α cos β - sin α sin β. Using this identity, we find:
cos(θ + π/6) = cos θ cos(π/6) - sin θ sin(π/6) = (-√(15)/4)(√(3)/2) - (1/4)(1/2) = -√(45)/8 - 1/8 = (-√(45) - 1) / 8.
what is this equation in slope intercept form? 4y+12x=0
The equation 4y + 12x = 0 in slope-intercept form is y = -3x. The slope (m) is -3, and since there is no constant term, the y-intercept (b) is 0.
Explanation:The equation provided, 4y + 12x = 0, can be converted into slope-intercept form, which is represented by y = mx + b. The slope, m, indicates the steepness of the line, while the y-intercept, b, denotes the y-value when x equals zero or where the line crosses the y-axis. Let's rearrange the equation step-by-step:
First, isolate the y variable by subtracting 12x from both sides: 4y = -12x.Next, divide each side by 4 to solve for y: y = -12x / 4.This simplifies to: y = -3x.Here, the slope (m) is -3, indicating a decrease in y by 3 units for every increase of 1 unit in x. The equation does not have a b term, thereby indicating that the y-intercept (b) is 0. Hence, the slope-intercept form of the equation is y = -3x + 0, which can be simplified to y = -3x.

The sine of an angle in a right triangle is equal to the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse. ...?
Answer: The given statement is FALSE.
Step-by-step explanation: We are given to check whether he following statement is true or false :
"The sine of an angle in a right triangle is equal to the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse. "
Let us consider the right-angled triangle ABC as shown in the attached figure below.
With respect to acute angle C, we can see that
perpendicular, p = AB
base, b = BC
and
hypotenuse, h = AC.
We know that
sine of an angle in a right-angled triangle is equal to the ratio of the perpendicular to the base.
So, we must have
[tex]\sin \angle C=\dfrac{p}{h}\\\\\\\Rightarrow \sin \angle C=\dfrac{AB}{AC}.[/tex]
Since AB is the opposite side to angle C, not adjacent, therefore
sine of any angle in a right-angled triangle is the ratio of the length of the OPPOSITE SIDE to length of the hypotenuse.
Thus, the given statement is FALSE.
Final answer:
The statement is false; sine is the ratio of the opposite side to the hypotenuse, not the adjacent side to the hypotenuse.
Explanation:
The statement is false. In a right triangle, the sine of an angle is defined as the ratio of the length of the side opposite to the angle to the length of the hypotenuse, not the adjacent side to the hypotenuse. Therefore, the sine of angle A would be expressed as sin(A) = opposite/hypotenuse. The ratio of the adjacent side to the hypotenuse, on the other hand, defines the cosine of the angle, which is cos(A) = adjacent/hypotenuse.

D.x^3+7x^2-13x+4
Final answer:
To simplify (x - 4)(x^2 + 3x - 1), use the FOIL method to distribute each term and combine like terms, resulting in x^3 - x^2 - 12x + 4 (option B).
Explanation:
To simplify the expression (x − 4)(x2 + 3x − 1), we need to use the distributive property, also known as the FOIL method, which stands for First, Outside, Inside, Last. We will multiply each term in the first binomial by each term in the second binomial.
Multiply the first terms: x * x2 = x3.Multiply the outside terms: x * 3x = 3x2.Multiply the inside terms: (-4) * x2 = -4x2.Multiply the last terms: (-4) * (3x) = -12x.Multiply the last terms: (-4) * (-1) = 4.Combine like terms:
x3 + 3x2 - 4x2 - 12x + 4
Simplify the expression by combining 3x2 and -4x2:
x3 - x2 - 12x + 4
Therefore, the simplified form of the expression is x3 - x2 - 12x + 4, which corresponds to option B.

Im totally lost! A sample from a refuse deposit near the Strait of Magellan had 60% of the carbon 14 of a contemporary living sample. Estimate the age of the sample ...?
Final answer:
The sample from the refuse deposit near the Strait of Magellan, with 60% carbon-14 remaining compared to a contemporary living sample, is estimated to be approximately 7777 years old, based on the known half-life of carbon-14 being 5730 years.
Explanation:
The age of a sample can be estimated using radiocarbon dating, which measures the decay of carbon-14 (14 C). Since the half-life of 14 C is known to be approximately 5730 years, we can use this information to estimate the age of the sample. Radiocarbon dating works on the principle that living organisms continually replenish carbon while alive, maintaining a constant level of 14 C relative to 12 C. When an organism dies, it no longer absorbs carbon, and the 14 C begins to decay at a known rate.
In the case of the refuse deposit near the Strait of Magellan, the sample had 60% of the carbon-14 of a contemporary living sample. To determine the age, we use the half-life formula, which is Time = Half-life / log2 (Starting amount / Remaining amount). Here, starting amount is 100% (contemporary living sample), the remaining amount is 60%, and the half-life is 5730 years.
So the calculation will be: Age of sample = 5730 / log2 (100/60). Calculating this, we get:
Age of sample = 5730 / log2 (1.6667)
Age of sample = 5730 / 0.737
Age of sample ≈ 7777 years
Thus, the sample from the refuse deposit near the Strait of Magellan is estimated to be approximately 7777 years old.

You deposit 6000 in an account that pays 5.25 interest compounded semiannually. after 10 years, the interest rate is increased to 5.4% compounded quarterly. what will be the value of the account after 18 years. (round to the nearest dollar)
The account value after 18 years with an initial deposit of $6,000 and a change in interest rate and compounding periods is approximately $15,526 when rounded to the nearest dollar.
Explanation:To calculate the value of the account after 18 years with a change in the interest rate and compounding periods, we need to use the compound interest formula separately for the two different periods and rates.
First, we compound the original $6,000 at 5.25% semiannually for 10 years:
A = P(1 + r/n)(nt)
A = $6,000(1 + 0.0525/2)(2*10) = $6,000(1.02625)20 = $9,984.21 (rounded)
Now, we take the amount after 10 years and compound it at 5.4% quarterly for the remaining 8 years:
A = P(1 + r/n)(nt)
A = $9,984.21(1 + 0.054/4)(4*8) = $9,984.21(1.0135)32 = $15,526.14 (rounded)
So, after 18 years, the value of the account would be $15,526 (rounded to the nearest dollar).

How many 20 cm by 30 cm rectangular tiles would you need to tile the outdoor are shown below?
I calculated that the area of the shape is 10.95m squared, but the answer in the book (183 tiles) is different then the answer I got.
Where did I go wrong?
The issue was inconsistent units - converting everything to cm squared, the appropriate number of 20 by 30 cm tiles to cover an area of 10.95m squared is 183.
Explanation:The problem here involves area measurement and conversions. The area of the outdoor space is given in square meters (m²), while the area of the tiles is given in square centimeters (cm²). Therefore, the first step here is to convert all measurements to the same unit.
Since 1 meter is equal to 100 centimeters, we can convert the area of the outdoor space to square centimeters by squaring 100 (which equals to 10,000) and then multiplying it by the area in square meters. That gives us 109,500 cm².
Next, to find the area of a single tile we multiply its length by its width, which is 20 cm by 30 cm, giving us 600 cm². The number of tiles needed will be the total area divided by the area of one tile. So, 109,500 cm² divided by 600 cm² equals to about 182.5.
Since we cannot have a half tile, we round up that number to 183 tiles. Therefore, the correct answer is 183 tiles.
