Christine's parents gave her $70 to spend at the Topsfield Fair. She spent $10 on flowers and needs to buy vases. Each antique flower vase at the fair costs $3. Which represents the number of antique flower vases Christine can buy?
Answer:
a ≤ 20
Step-by-step explanation:
a = number of lower vases, in $
3a = cost of a flower vases, in $
10 + 3a = = cost of $10 worth of flowers plus a vases
10 + 3a ≤ 70 says that the cost of Christine's flowers and vases purchase
must be less than, or at most equal to $70.
Subtracting 10 rom both sides of the inequalour
gives us an equivalent inequality
3a ≤ 70 - 10 <---> 3a ≤ 60
Multiplying (or dividing) both sides by a positive number
gives us an equivalent inequality, so
a ≤ 60/3 <---> a ≤ 20
A baseball pitcher allowed 3 runs in 9 innings. At that rate, how many runs would he allow in 36 innings?
ANSWER
12 runs
EXPLANATION
We have that the baseball pitcher allowed 3 runs in 9 innings.
Let the number of runs he allowed in 36 innings be x.
This means that:
3 runs = 9 innings
x runs = 36 innings
Cross-multiply:
=> 3 * 36 = 9 * x
Divide both sides by 9:
\(\begin{gathered} x\text{ = }\frac{3\cdot\text{ 36}}{9} \\ x\text{ = }12\text{ runs} \end{gathered}\)Therefore, at this rate he would allow 12 runs
The cost of a newspaper subscription
includes a discounted initial week. Beatriz
pays $55 for 7 weeks of the newspaper
subscription and $100 for 12 weeks.
As a result, the original discounted price is $1 while the weekly normal price is $9.
How does arithmetic work with discounts?The fundamental formula for calculating a reduction is to increase the initial price by the provided percentage rate in decimal form. We must deduct the reduction from the initial price to determine the item's sale price.
From the given information, we have:
d + 6x = 55 (discounted price for 7 weeks)
d + 11x = 100 (discounted price for 12 weeks)
We can solve this system of equations by eliminating d. Subtracting the first equation from the second, we get:
5x = 45
Dividing both sides by 5, we get:
x = 9
Substituting x = 9 into one of the equations, we can solve for d. Using the first equation, we get:
d + 6(9) = 55
d + 54 = 55
d = 1

What is the probability of getting 3 heads in 4 coin tosses, given you get at least 2 heads?
The probability of getting 3 heads in 4 coin tosses, given that we get at least 2 heads, is 4/11 or 0.364.
To solve this problem, we can use the conditional probability formula. Let A be the event of getting 3 heads in 4 coin tosses, and let B be the event of getting at least 2 heads in 4 coin tosses. Then we want to find P(A|B), the probability of getting 3 heads in 4 coin tosses given that we get at least 2 heads.
By the definition of conditional probability, we have:
P(A|B) = P(A and B) / P(B)
To find P(B), the probability of getting at least 2 heads in 4 coin tosses, we can use the complement rule and find the probability of getting 0 or 1 heads:
P(B) = 1 - P(0 heads) - P(1 head)
To find P(0 heads), the probability of getting 0 heads in 4 coin tosses, we use the binomial probability formula:
P(0 heads) = (4 choose 0) * (0.5)^0 * (1-0.5)^(4-0) = 1/16
Similarly, we can find P(1 head):
P(1 head) = (4 choose 1) * (0.5)^1 * (1-0.5)^(4-1) = 4/16
So,
P(B) = 1 - P(0 heads) - P(1 head) = 11/16
To find P(A and B), the probability of getting 3 heads in 4 coin tosses and getting at least 2 heads, we can use the binomial probability formula again:
P(A and B) = (4 choose 3) * (0.5)^3 * (1-0.5)^(4-3) = 4/16
Therefore,
P(A|B) = P(A and B) / P(B) = (4/16) / (11/16) = 4/11
So the probability of getting 3 heads in 4 coin tosses, given that we get at least 2 heads, is 4/11 or approximately 0.364.

A zip wire runs between two posts, 25m apart. The zip wire is at an angle of 10 degrees to the horizontal. Calculate the length of the zip wire.

to the horizontal. Calculate the length of the zip wire
The length of the zip wire, with a 10-degree angle to the horizontal and a distance of 25 meters between the posts, is approximately 25.35 meters.
To calculate the length of the zip wire, we can use trigonometry. Let's consider the triangle formed by the zip wire, where the horizontal distance between the two posts is 25 meters and the angle between the zip wire and the horizontal is 10 degrees.
Using trigonometric functions, we can determine the length of the zip wire. In this case, we'll use the sine function because we have the opposite side (the vertical distance) and we want to find the hypotenuse (the length of the zip wire).
The formula for sine is:
sin(angle) = opposite / hypotenuse
Rearranging the formula, we have:
hypotenuse = opposite / sin(angle)
In this case, the opposite side is the vertical distance, which is h.
So, the formula becomes:
hypotenuse = h / sin(angle)
To find h, we can use the formula for the length of the zip wire:
h = 25 * tan(angle)
Substituting this into the previous formula, we get:
hypotenuse = (25 * tan(angle)) / sin(angle)
Calculating the value, we have:
hypotenuse = (25 * tan(10°)) / sin(10°)
Using a calculator, we find:
tan(10°) ≈ 0.1763
sin(10°) ≈ 0.1736
Substituting these values, we can calculate the length of the zip wire:
hypotenuse ≈ (25 * 0.1763) / 0.1736 ≈ 25.35 meters
Therefore, the length of the zip wire is approximately 25.35 meters.

Solve the initial-value problem: y" - 4y' + 8y = 0, y(0) = 1, y'(0) = 2.
Answer:
The solution of the problem is \(y(t) = e^{2 t} cos(2 t)\)
Step-by-step explanation:
First we will write the characteristic equation which is
\(x^{2} -4x + 8 = 0\)
Now, we will solve this quadratic equation using the general formula.
Given a quadratic equation of the form, \(ax^{2} +bx +c = 0\), then
From the general formula,
\(x = \frac{-b+\sqrt{b^{2}-4ac } }{2a}\) or \(x = \frac{-b-\sqrt{b^{2}-4ac } }{2a}\)
From the characteristic equation, \(a = 1, b = -4,\) and \(c = 8\)
Hence,
\(x = \frac{-(-4)+\sqrt{(-4)^{2}-4(1)(8) } }{2(1)}\) or \(x = \frac{-(-4)-\sqrt{(-4)^{2}-4(1)(8) } }{2(1)}\)
\(x = \frac{4+\sqrt{-16} }{2}\) or \(x = \frac{4-\sqrt{-16} }{2}\)
\(x = \frac{2+4i }{2}\) or \(x = \frac{2-4i }{2}\)
\(x = 2 + 2i\) or \(x = 2 - 2i\)
That is, \(x\) = \(2\) ± \(2i\)
Then, \(x_{1} = 2 + 2i\) and \(x_{2} = 2 - 2i\)
These are the roots of the characteristic equation
The roots of the characteristic equation are complex, that is, in the form
(\(\alpha\) ± \(\beta i\)).
For the general solution,
If the roots of a characteristic equation are in the form (\(\alpha\) ± \(\beta i\)), the general solution is given by
\(y(t) = C_{1}e^{\alpha t} cos(\beta t) + C_{2}e^{\alpha t} sin(\beta t)\)
From the characteristic equation,
\(\alpha = 2\) and \(\beta = 2\)
Then, the general solution becomes
\(y(t) = C_{1}e^{2 t} cos(2 t) + C_{2}e^{2 t} sin(2t)\)
Now, we will determine \(y'(t)\)
\(y'(t) = 2C_{1}e^{2 t} cos(2 t) - 2C_{1}e^{2t}sin(2t) + 2C_{2} e^{2t}sin(2t) +2C_{2}e^{2t}cos(2t)\)
From the question,
y(0) = 1
and
y'(0) = 2
Then,
\(1 = y(0) = C_{1}e^{2 (0)} cos(2 (0)) + C_{2}e^{2 (0)} sin(2(0))\)
\(1 = C_{1}e^{ 0} cos(0) + C_{2}e^{0} sin(0)\)
(NOTE: \(e^{0} = 1, cos(0) = 1\) and \(sin(0) = 0\) )
Then,
\(1 = C_{1}\)
∴\(C_{1} = 1\)
Also,
\(2 = y'(0) = 2C_{1}e^{2 (0)} cos(2 (0)) - 2C_{1}e^{2(0)}sin(2(0)) + 2C_{2} e^{2(0)}sin(2(0)) +2C_{2}e^{2(0)}cos(2(0))\)\(2 = 2C_{1}e^{0} cos(0) - 2C_{1}e^{0}sin(0) + 2C_{2} e^{0}sin(0) +2C_{2}e^{0}cos(0)\)
\(2 = 2C_{1} +2C_{2}\)
Then,
\(1 = C_{1} +C_{2}\)
\(C_{2} = 1 - C_{1}\)
Recall, \(C_{1} = 1\)
∴ \(C_{2} = 1 - 1 = 0\)
\(C_{2} = 0\)
Hence, the solution becomes
\(y(t) = e^{2 t} cos(2 t)\)

how much would we pay per barrel of crude oil if the price goes up to US$ 75 and the US$ exchange rate drops to 5.865?
If the price per barrel of crude oil goes up to US$75 and the U.S. dollar exchange rate drops to 5.865, the amount to be paid per barrel of crude oil is $439.875 in the domestic currency.
What is the effect of the exchange rate on oil prices?When the price of oil increases, there is a depreciation of the U.S. dollar's exchange rate.
Similarly, when the U.S. dollar weakens, crude oil prices increase.
The implication is that a stronger U.S. dollar ensures that fewer U.S. dollars are spent to purchase a barrel of oil. On the other hand, when the U.S. dollar is weak, the price of oil is higher in dollar terms.
Thus, if the price per barrel of crude oil goes up to US$75 and the U.S. dollar exchange rate drops to 5.865, the amount to be paid per barrel of crude oil is $439.875 in the domestic currency.
