Let x be the number of hour babyitting and y be the number of hour tutoring. Part A Select the inequality that repreent the number of hour Samir could work to earn enough to buy the game ytem. Part A
Select the inequality that repreent the number of hour Samir could work to earn enough to buy the game ytem. A) y≥ − 0. 6x 45
B) y ≥ − 123x 75
C) y > 123x − 75
D) y > 6x 10
Answer:
Step-by-step explanation:
The required inequality is y ≥ - 0.6x + 45 which represents the number of hours Samir could work to earn enough to buy the game system. which is the correct answer would be an option (A).
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
The video game system will cost at least $450.
He earns $6 per hour babysitting and $10 per hour tutoring.
Let x be the number of hours babysitting and y be the number of hours of tutoring.
According to the given situation, we can write the inequality would be as:
⇒ 6x + 10y ≥ 450
Rearrange the terms of variables in the above inequality,
⇒ 10y ≥ 450 - 6x
Divided by 10 into both sides of the above inequality,
⇒ 10y/10 ≥ 450/10 - 6x/10
⇒ y ≥ 45 - 0.6x or
⇒ y ≥ - 0.6x + 45
Thus, the required inequality is y ≥ - 0.6x + 45 which represents the number of hours Samir could work to earn enough to buy the game system.

Over the last three evenings, Maria received a total of 154 phone calls at the call center. The second evening, she received 10 more calls than the first evening. The third evening, she received 4 times as many calls as the first evening. How many phone calls did she receive each evening?Number of phone calls the first evening:Number of phone calls the second evening:Number of phone calls the third evening:
Data
• Total phone calls: 154
,• Second evening ( ,s ,): 10 more calls than the first evening ( ,f ,)
,• Third evening ( ,t ,): 4 times as many calls as ,f
Procedure
We have to translate the given information into algebraic expressions.
• Maria received a total of 154 phone calls at the call center:
\(f+s+t=154\)where f represents the first evening, s the second, and t the third.
• The second evening, she received 10 more calls than the first evening:
\(s=10+f\)• The third evening, she received 4 times as many calls as the first evening:
\(t=4\times f\)As t and s can be used in terms of f, we will replace the second and third equations that we build in the first one:
\(f+s+t=154\)\(f+(10+f)+(4\times f)=154\)Eliminating the parenthesis we get:
\(f+10+f+4f=154\)Solving for f:
\(6f=154-10\)\(f=\frac{144}{6}\)\(f=24\)Thus, the number of phone calls the first evening was 24.
Then, we have to replace this calculated value in the other equations to get s and t.
• Solving for ,s
\(s=10+f\)\(s=10+24\)\(s=34\)• Solving for ,t
\(t=4f\)\(t=4\cdot24\)\(t=96\)To prove our answers are correct, we can do the following:
\(24+34+95=154\)\(154=154\)Answer
• Number of phone calls the first evening: 24
• Number of phone calls the second evening: 34
• Number of phone calls the third evening: 96

find the area of the region inside the circle r=4cosθ and to the right of the vertical line r=secθ.
The area of the region inside the circle r = 4cos(θ) and to the right of the vertical line r = sec(θ) is \(2\pi - 2\cos^{-1}\left(\frac{1}{4}\right) - \sqrt{15}\).
To find the area of the region inside the circle r = 4cos(θ) and to the right of the vertical line r = sec(θ), we need to determine the limits of integration for θ.
First, let's find the values of θ where the circle and the vertical line intersect:
r = 4cos(θ)
sec(θ) = 4cos(θ)
To simplify the equation, let's convert sec(θ) to its reciprocal form:
1/cos(θ) = 4cos(θ)
Multiplying both sides by cos(θ), we get:
1 = 4\(cos^2\)(θ)
Rearranging the equation, we have:
4\(cos^2\)(θ) - 1 = 0
Using the identity \(cos^2\)(θ) - \(sin^2\)(θ) = 1, we can rewrite the equation as:
\(cos^2\)(θ) - \(sin^2\)(θ) = 1/4
Applying the double-angle formula for cosine, we get:
cos(2θ) = 1/4
Taking the inverse cosine of both sides, we have:
2θ = ± \(\cos^{-1}\left(\frac{1}{4}\right)\)
Solving for θ, we get two values:
θ = ± (1/2) \(\cos^{-1}\left(\frac{1}{4}\right)\)
Since we are interested in the region to the right of the vertical line, we'll consider the positive value of θ:
θ = (1/2) \(\cos^{-1}\left(\frac{1}{4}\right)\)
Now, we can find the area by evaluating the integral:
A = ∫[θ, π/2] 1/2 (\(r^2\)) dθ
Substituting the equations for r, we have:
\(A = \int_{\theta}^{\frac{\pi}{2}} \frac{1}{2} (4\cos^2(\theta)) \, d\theta\)
Simplifying further:
\(A = \int_{\theta}^{\frac{\pi}{2}} 8\cos^2(\theta) \, d\theta\)
Using the double-angle formula for cosine, we have:
A = ∫[θ, π/2] 4(1 + cos(2θ)) dθ
Integrating term by term, we get:
A = [4θ + 2sin(2θ)] evaluated from θ to π/2
Now, Substituting the limits of integration, we get:
A = [4(π/2) + 2sin(2(π/2))] - [4θ + 2sin(2θ)] evaluated from θ to π/2
Simplifying:
A = 2π + 2sin(π) - (4θ + 2sin(2θ))
Since sin(π) = 0, we can simplify further:
A = 2π - (4θ + 2sin(2θ))
Now, we need to substitute the value of θ, which we found earlier:
θ = (1/2) \(\cos^{-1}\left(\frac{1}{4}\right)\)
Substituting this value, we have:
A = 2π - (4(1/2) \(\cos^{-1}\left(\frac{1}{4}\right)\) + 2sin(2(1/2) \(\cos^{-1}\left(\frac{1}{4}\right)\)))
Simplifying:
A = 2π - (2 \(\cos^{-1}\left(\frac{1}{4}\right)\) + 2sin(\(\cos^{-1}\left(\frac{1}{4}\right)\)))
Since cos(\(\cos^{-1}\left(x\right)\)) = x, we have:
A = 2π - (2 \(\cos^{-1}\left(\frac{1}{4}\right)\) + 2(√(1 - (1/4)^2)))
Simplifying further:
A = 2π - (2 \(\cos^{-1}\left(\frac{1}{4}\right)\) + 2(√(15/16)))
A = 2π - 2 \(\cos^{-1}\left(\frac{1}{4}\right)\) - √15
So, the area of the region inside the circle r = 4cos(θ) and to the right of the vertical line r = sec(θ) is \(2\pi - 2\cos^{-1}\left(\frac{1}{4}\right) - \sqrt{15}\).

A. d = 2.67
B. d = 3.67
C. d = 5.57
D. d = 5.67
Answer: A d=2.67
Step-by-step explanation:
Simplifying

In ΔGHI, g = 3.4 cm, i = 8.2 cm and ∠I=29°. Find all possible values of ∠G, to the nearest 10th of a degree.
Answer:
11.6°
Step-by-step explanation:
In ΔGHI, g = 3.4 cm, i = 8.2 cm and ∠I=29°. Find all possible values of ∠G, to the nearest 10th of a degree.
We solve the above question using Law of Sines
= g/sin G = I / sin I
Substituting
= 3.4/ sin G= 8.2/ sin 29
Cross Multiply
3.4 × sin 29 = sin G × 8.2
sin G = 3.4 × sin 29/ 8.2
G = arc sin[3.4 × sin 29/ 8.2]
G = arcsin [0.2]
G = 11.59653°
Approximately = 11.6°
∠G = 11.6°
Given that f(x)=x^2=11x+30 and g(x)=x-5, find f(-g)(x) and express the result as a polynomial in simplest form.
Hey there,
We have,
f(x) = x² + 11x + 30g(x) = x + 6
Now,
(f.g)(x) = f(g(x))
Substituting...
g(x) = x + 6f(g(x)) = f(x + 6)
Now,
f(x + 6)= (x + 6)² + 11(x + 6) + 30= x² + 12x + 36 + 11x + 66 + 30= x² + 23x + 132
So,The value is x² + 23x + 132
the cookies in a jar contain a total of 1000 chocolate chips. all but one of these cookies contains the same number of chips; it contains one more chip than the others. the number of cookies in the jar is between one dozen and three dozen. what is the sum of the number of cookies in the jar and the number of chips in the cookie with the extra chocolate chip?
The total number of chocolate chips in the cookies is 1000. All the cookies, except one, have the same number of chips, while the remaining cookie has one more chip than the others. The number of cookies in the jar is between one dozen (12 cookies) and three dozen (36 cookies).
To find the sum of the number of cookies in the jar and the number of chips in the cookie with the extra chocolate chip, we can follow these steps:
1. Let's assume the number of cookies in the jar is "x". Since the number of cookies is between one dozen and three dozen, we have the inequality: 12 ≤ x ≤ 36.
2. Since all the cookies, except one, have the same number of chips, we can divide the total number of chocolate chips by the number of cookies minus one. This gives us the number of chips in each cookie (excluding the one with the extra chip). So, the number of chips in each cookie is 1000 ÷ (x - 1).
3. The cookie with the extra chip has one more chip than the others. Therefore, the number of chips in the cookie with the extra chip is 1000 ÷ (x - 1) + 1.
4. To find the sum of the number of cookies in the jar and the number of chips in the cookie with the extra chocolate chip, we add the number of cookies (x) and the number of chips in the extra chip cookie (1000 ÷ (x - 1) + 1).
Remember that the number of cookies in the jar is between one dozen and three dozen, so the sum will vary depending on the number of cookies. You can substitute different values within the given range (12 ≤ x ≤ 36) to find different possible sums.

Use the integration capabilities of a graphing utility to approximate to two decimal places the area of the surface formed by revolving the polar equation over the given interval about the polar axis. r = 7 cos(20), [0, Phi/4]
The approximate area of the surface formed by revolving the polar equation over the given interval about the polar axis is 67.59 square units.
To solve the question, we can use the integration capabilities of a graphing utility to approximate to two decimal places the area of the surface formed by revolving the polar equation over the given interval about the polar axis. Polar curve is a type of curve that is made up of points that represent polar coordinates (r, θ) instead of Cartesian coordinates.
A polar curve can be represented in parametric form, but it is often more convenient to use the polar equation for a curve. According to the question, r = 7 cos(20), [0, Phi/4] is the polar equation and we need to find the approximate area of the surface formed by revolving the polar equation over the given interval about the polar axis.
To solve the problem, follow these steps: Convert the polar equation to a rectangular equation. The polar equation r = 7 cos(20) is converted to a rectangular equation using the following formulas: x = r cos θ, y = r sin θx = 7 cos (20°) cos θ, y = 7 cos (20°) sin θx = 7 cos (θ - 20°) cos 20°, y = 7 cos (θ - 20°) sin 20°
Sketch the curve in the plane. We can sketch the curve of r = 7 cos(20) by plotting the points (r, θ) and then drawing the curve through these points. Use the polar equation to set up the integral for the volume of the solid of revolution.
The volume of the solid of revolution is given by the formula: V = ∫a b πf2(x) dx where f(x) = r, a = 0, and b = Φ/4.We can find the volume of the solid of revolution using the polar equation: r = 7 cos(20) => r2 = 49 cos2(20) => x2 + y2 = 49 cos2(20)Thus, f(x) = √(49 cos2(20) - x2) = 7 cos(20°) sin(θ - 20°)
So, V = ∫a b πf2(x) dx = ∫0 Φ/4 π(7 cos(20°) sin(θ - 20°))2 dθStep 4: Use a graphing utility to evaluate the integral to two decimal places. Using a graphing utility to evaluate the integral, we get V ≈ 67.59.
