1. PHONES Acme Phone Company charges $21 a month plus $0.05 a minute. Belltone
Phones charges $15 a month plus $0.11 a minute. Write and solve an equation to
determine how many minutes a month you must use for the costs of using either
company to be equal.
Answer:
10 minutes
Step-by-step explanation:
Let's call the Acme Company A and Beltone as B
Let m be the number of minutes
A = $21 + $0.05m
B = $15 + $0.11m
A = B$21 + $0.05m = $15 + $0.11m$6 + $0.05m = $0.11m$6 = $0.06m10 = mIt will take 10 minutes for both prices to be equal.

One of the goats on Diane's farm is sick and has a high fever. Over the course of 4 hours, its
temperature changes by-2.8°F. Diane wants to know the average change in the goat's
temperature per hour.
• Write an expression for the average change in the goat's temperature each hour.
- 2.8
4
Answer:
-2.8 / 4
Step-by-step explanation:
The equivalent expression for the change in the goat's temperature each hour is A = -0.7°F/hour
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let's say the initial temperature of the goat was T1, and the final temperature after 4 hours was T2.
Now , the total change in temperature over the 4 hours is:
T2 - T1 = -2.8°F
The average change in temperature per hour can be expressed as:
The average change in temperature per hour = total change in temperature / number of hours
The average change in temperature per hour = (-2.8°F) / 4 hours
On simplifying the equation , we get
The average change in temperature per hour = -0.7°F/hour
Hence , the expression for the average change in the goat's temperature each hour is A = -0.7°F/hour

The sound wave of two music notes can be represented by the function y = 2cos2x and y = −cos x, where x represents the time since the note is played. At what times will the frequencies of the sound waves be the same in the interval [0°, 360°)?
x = 0°, 60°, 180°, 300°
x = 0°, 120°, 240°, 180°
x = 60°, 90°, 270°, 300°
x = 90°, 120°, 240°, 270°
The sound waves are illustrations of cosine functions
The frequencies of the sound waves are x = 90°, 120°, 240°, 270°
How to determine the frequencies of the sound wavesThe equations of the sound waves are given as:
[tex]y = 2\cos^2(x)[/tex]
[tex]y =-\cos(x)[/tex]
Next, we plot the graphs of the functions [tex]y = 2\cos^2(x)[/tex] and [tex]y =-\cos(x)[/tex]
From the graphs of the functions (see attachment), we have the following x-coordinates of the points of intersection of the both curves between the interval [0°, 360°)
[tex]x =(\frac{\pi}{2},\frac{2\pi}{3},\frac{4\pi}{3},\frac{3\pi}{2})[/tex]
Express as degrees
[tex]x =(90^o,120^o, 240^o, 270^o)[/tex]

Step-by-step explanation:
Greatest Common Factor
- first list all the numbers that could be multiplied to the factors given.
30 = 1, 2, 3, 5, 6, 10, 15, & 30
24 = 1, 2, 3, 4, 6, 8, 12 & 24
- then you find the common number between them but the highest one (which is 6)
Least Common Multiple
- so we could say this is the opposite of the greatest common factor
3 = 3, 6, 9, 12, 15, 18
4 = 4, 8, 12, 16, 20

Find the area of the shaded region. The length of AC is 10 meters and the m angle CAD=140 degrees . Round your answer to the nearest tenth (don't include units).
Answer:
122 m²
Step-by-step explanation:
Radius r = 10 m.
For a whole circle, the area is πr², that is for 360° at the center.
Now the angle is 140°, so the area of the shaded region is (140/360) πr² = 140 * 3.14 * 100/360 = 122 m²
what is the slope-intercept equation for this line?
y=-3x + 4
Slope intercept form is y=mx+b
m = slope
b = y-intercept
If you look on the graph, you can see that 4 is the point in which it is intercepted on the y-axis, so that is the y-intercept. This means that b is 4.
b=4

4x^2-11x=78 quadratic formula
Assume that the weight loss for the first month of a diet program varies between 6 pounds and 14 pounds, and is spread evenly over the range of possibilities, so that there is a uniform distribution. Find the probability of the given range of pounds lost.
1) P(x = 7)
2) Between 8.25 po9unds and 12 pounds.
3) Greater than 10.50 pounds.
Please show work.
Hello!
For this uniform distribution, the shape of the density function is a line. We can begin by identifying key elements of the distribution:
Range: 6 to 14 pounds
Formula of density function:
y = 1/Range
1 - (14 - 6) = 1/8 = 0.125
f(x) = 0.125
1)
P(x = 7)
A uniform distribution is a continuous distribution, so the probability of x being an EXACT value is approximately 0.
This is the same as if we took the following integral. (Finding the area under a curve with the same start and end point)
[tex]\int\limits^a_a {f(x)} \, dx = 0[/tex]
Therefore, P(x = 7) = 0.
2)
We can think of this as finding the area of a rectangle.
The width would be the difference between 8.25 pounds and 12 pounds:
W = 12 - 8.25 = 3.75
The height would be the function (y = .125), or:
h = .125
Using the equation for the area of a rectangle: (A = h * w)
A = 3.75 * .125 = 0.469
Thus, P(8.25 < x < 12) = 0.469
3)
To find the probability GREATER than 10.50 pounds, we can subtract this value from the max value for the width:
W = 14 - 10.50 = 3.50
The height is the same as above:
h = .125
Solve for the area:
A = 3.50 * .125 = 0.4375
P(x > 10.5) = 0.4375
Solve the following inequality.
2P - 3 > P + 6
Answer:

P > 9
your final answer is P > 9

find quotient
find remainder
Answer:
quotinet = 3x² - 2x - 2
remainder = 7
Step-by-step explanation:
12x³ - 2x² - 12x + 3
= 3x²(4x + 2) - 6x² - 2x² - 12x + 3
= 3x²(4x + 2) - 8x² - 12x + 3
= 3x²(4x + 2) - 2x(4x + 2) + 4x - 12x + 3
= 3x²(4x + 2) - 2x(4x + 2) - 8x + 3
= 3x²(4x + 2) - 2x(4x + 2) - 2(4x + 2) + 4 + 3
= 3x²(4x + 2) - 2x(4x + 2) - 2(4x + 2) + 7
= (4x + 2)(3x² - 2x - 2) + 7
so
quotinet = 3x² - 2x - 2
remainder = 7

sally can paint a room in 3 hours while it takes steve 8 hours to paint the same room. how long would it take them to paint the room if they worked together ?
Answer:
2 hours 11 minutes
Step-by-step explanation:
Each hour Sally can paint 1/3 rooms, Steve can paint 1/8 rooms.
If they work together, each hour they can paint 1/3 + 1/8 = 11/24 rooms.
So They will take 1/(11/24) = 24/11 = 2.18 hours to paint a whole room.
2.18 hours = 2 hours 0.18*60 minutes
0.18 * 60 = 11
Answer: 2 hours 11 minutes
