A doctor is administrating medicine to a patient and needs to adjust the dosage based on the patients weight. The number of teaspoons of medicine t that a person of a certain weight w, in pounds, should take is approximated by the equation t=3+0.05w. Which of the following is the appropriate dosage of medicine, in ounces, for the doctor to administer to a 180 lb person?
Answer: The appropriate dosage of medicine for a 180 Ib person is 12 ounces.
Step-by-step explanation:
From the word problem, we know that:
t = number of teaspoons of medicinew = the weight of the personequation: t= 3 + 0.05wThe person weighs 180 lbSince we are given w (the amount the person weighs is 180 Ib), we can plug the value into the equation to solve for t.
t= 3 + 0.05 (180)
t = 3 + 9
t = 12
So the appropriate dosage of medicine for a 180 Ib person is 12 ounces.

QUESTION: AOB is a right isosceles triangle of vertex O. [OH] is the altitude relative to [AB]. P is the symmetric of H with respect to (OA).
Prove that OHAP is a square.
×i have did half of the question i still the other half, how to proof HA=PA so i xan prove it as a rhombus then to a square.PLEASE HELP I NEEEED ITT NOWWW!
Answer:
Step-by-step explanation:
To prove that OHAP is a square, we need to show that all four sides are congruent and all four angles are right angles.
Since AOB is a right isosceles triangle, we know that angle OAB and angle OBA are both congruent to 90 degrees, which means that they are both right angles. Since [OH] is the altitude relative to [AB], it bisects angle OAB, which means that angle AOH and angle HOA are both congruent to 45 degrees. Since P is the symmetric of H with respect to OA, we know that OA is congruent to OP, and we also know that OH is congruent to OP. Therefore, all four sides of OHAP are congruent, which means that OHAP is a square.
if the radius of the circle below is 9m find the approximate area of the shaded region
The approximate area of the shaded region of the circle is 191 metres squared.
How to find the area of a region in a circle?The radius of the circle below is given as 9 metres. The approximate area of the shaded region of the circle can be found as follows:
area of the shaded region = area of the circle - area of the sector uncoloured
Therefore,
area of the circle = πr²
where
r = radiusTherefore,
area of the circle = π × 9²
area of the circle = 81π m²
Hence,
area of the sector uncoloured = ∅ / 360 × πr²
where
∅ = central angler = radiusTherefore,
area of the sector uncoloured = 90 / 360 × π × 9²
area of the sector uncoloured = 1 / 4 × π × 81
area of the sector uncoloured = 81 / 4 π
Hence,
area of the shaded region = 81π - 20.25π
area of the shaded region = 60.75π
area of the shaded region = 190.755

We shall evaluate the domain of the function f(g(x)) as follows:
f(g(x)) = 1 ÷ 12/[(x - 2) + 4]
f(g(x)) = 1 ÷ [12 + 4(x - 2)]/(x - 2) {simplify the denominator to a single fraction}

One aircraft has a capacity of 64 more seats than a second
aircraft. A third aircraft has 152 seats less than twice the seating
capacity of the second aircraft. If their total number of seats is
1900, find the number of seats for each aircraft.
Using the provided conditions and values, This is solved with the concept of word problem, The answer is first, second and third aircrafts have 576,512 and 864 seats.
What is word problem?A word problem in mathematics is a problem that is written in natural language (i.e., words) rather than in mathematical notation. It presents a real-world scenario that requires the use of mathematical concepts and skills to solve. Word problems often involve finding unknown quantities based on given information, and they can be challenging because they require students to understand the problem and translate it into mathematical equations or formulas. They are often used in primary and secondary education to help students apply their math skills to real-world situations and develop critical thinking skills.
What do you mean by mathematical expression?A mathematical expression is a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) that represents a mathematical statement or equation. Mathematical expressions can be evaluated to find a numerical value. They can also be simplified by applying the order of operations (PEMDAS) to combine like terms or to remove unnecessary parentheses. Additionally, mathematical expressions can also be used to represent the relationship between different variables.
Let x be the number of seats on the second aircraft. Then, the first aircraft has x+64 seats and the third aircraft has 2x-152 seats.
We know that the total number of seats for all three aircraft is 1900, so we can set up the following equation:
x + (x+64) + (2x-152) = 1900
Solving this equation gives us x = 512, which means the second aircraft has 512 seats. We can then use this information to find the number of seats for the other two aircraft:
First aircraft: 512 + 64 = 576 seats
Third aircraft: 2(512) - 152 = 864 seats.

ment with a Future Value of $2,000?
Answer:
To find out how many years it would take to double an initial investment with a 1% annual interest rate, you can use the rule of 72. The rule of 72 states that you can divide 72 by the annual interest rate to find out how many years it would take to double an investment.
In this case, you would divide 72 by 1 to get 72 years. Therefore, it would take 72 years for an investment of $1,000 at a 1% annual interest rate to have a future value of $2,000.

The curved surface area of a cylindrical lampshade is 3520cm₂ . if the height is 40cm calculate its radius (Take π = 3.142) PLS HELP
Answer:
Step-by-step explanation:
S= 2πrh
<=> 3520= 2x3.142xrx40
=> r ≈ 14
The radius of the cylindrical lampshade is approximately 13.98 cm.
The formula for the curved surface area of a cylinder is 2πrL, where r is the radius, L is the height and π is pi. Given that the curved surface area of a cylindrical lampshade is 3520 cm² and the height is 40cm.
We know that:
2πrL = 3520cm²
So we can solve for the radius by dividing both sides by 2πL:
r = 3520cm² / (2π * 40cm)
Substituting the value of pi we have
r = 3520cm² / (6.284 * 40cm) = 3520cm² / 251.36cm = 13.98cm
The radius of the cylindrical lampshade is approximately 13.98 cm.

1. On June 10, Bertha Wooten deposited $8,241.78 in a
that pays 5.5% interest compounded
savings account daily. How much interest will the money earn in 31 days?
Answer:
To calculate the interest earned on an investment, we can use the formula:
A = P(1 + r)^t
Where A is the amount in the account after time t, P is the initial principal or deposit, r is the interest rate, and t is the time in years.
In this case, the initial deposit is $8,241.78, the interest rate is 5.5% (or 0.055 as a decimal), and the time is 31 days.
Since the interest is compounded daily, we need to calculate the number of compounding periods for 31 days, which is 31 days.
Therefore, the formula becomes:
A = 8241.78(1+0.055)^31
To calculate the interest earned, we will subtract the initial deposit from the final amount in the account
Interest = A - P
So the interest earned in 31 days will be:
$8241.78 * (1+ 0.055)^31 - $8241.78 = $35094.06

Hi, can any of you help me with this circle question?
Answer:
We can use the formula for the area of a circle and the information provided to find the approximate area of the circle.
The formula for the area of a circle is A = πr², where r is the radius of the circle.
We know that the distance from the center of the circle to the chord AB is 6 and the length of the chord AB is 10.
We can use the Pythagorean theorem to find the radius of the circle.
The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
So, we can use this theorem to find the radius of the circle as follows:
r² = (length of the chord /2)² + (distance of the chord to the center)²
r² = (10/2)² + 6²
r² = 25 + 36
r² = 61
r ≈ 7.8
Now that we know the radius of the circle, we can use the formula for the area of a circle to find the area of the circle:
A = πr²
A ≈ π (7.8)²
A ≈ 191.8
The approximate area of the circle is 192 square units.
