Good lessons!
Final answer:
The correct equation that expresses how many days Meghan used her cell phone is 45n = 540. By dividing both sides by 45, we find that n = 12, indicating she used her cell phone for 12 days.
Explanation:
The question is asking to find the equation that represents the number of days Meghan used her cell phone, given that she used it for 45 minutes each day and the total usage was 540 minutes. To solve this, you would set up an equation where the number of days (n) times the daily usage (45 minutes) equals the total usage (540 minutes).
Therefore, the correct equation would be 45n = 540.
To find out how many days she used her cell phone, you would divide both sides of the equation by 45:
45n / 45 = 540 / 45
n = 12
This means Meghan used her cell phone for 12 days.

Final answer:
To calculate the simple interest on a $400 necklace purchase with a 21.3% interest rate after 15 months, use the simple interest formula I = PRT, resulting in an interest of $106.50.
Explanation:
To calculate the simple interest added to a $400 necklace purchase with a credit card charging 21.3% simple interest after 15 months, you can use the formula for simple interest: I = PRT, where I is the interest, P is the principal amount (initial loan balance), R is the rate of interest per year, and T is the time in years. In this question, P = $400, R = 21.3% or 0.213, and T = 15/12 years (to convert months to years).
First, convert the interest rate to a decimal by dividing by 100:
R = 21.3% \/ 100 = 0.213
Next, convert the time from months to years:
T = 15 months \/ 12 = 1.25 years
Finally, calculate the simple interest:
I = P times R times T
I = $400 times 0.213 times 1.25
I = $106.50
Therefore, the interest added after 15 months would be $106.50.

Solve the inequality and graph the solution g-3>6
Answers
Answer: It should be g > 9
Step-by-step explanation:
-Solve:
[tex]g-3>6[/tex]
[tex]g-3+3>6+3[/tex]
[tex]g>9[/tex]
So, Therefore, the result is g > 9
The solution to the inequality is g > 9.
Here, we have,
To solve the inequality g - 3 > 6, we will isolate the variable g.
Adding 3 to both sides of the inequality, we get:
g - 3 + 3 > 6 + 3
Simplifying, we have:
g > 9
So, the solution to the inequality is g > 9.
To graph the solution on a number line, we represent all values of g that are greater than 9. We can denote this by shading the region to the right of 9 on the number line.
Here's a graphical representation:

In this representation, the open circle (o) indicates that 9 itself is not included in the solution since the inequality is strict (g > 9). The shaded region represents all values of g that are greater than 9.
Please note that the number line extends indefinitely in both directions, but only the relevant portion is shown here for clarity.

Two hoses of different sizes are used to fill a pool. The smaller hose can fill the pool in 1.5 times as long as the larger hose. If both hoses
are used it takes 9 hours to fill the pool. If only the larger hose is used, how many hours will it take to fill the pool?
Answers
Answer:
15
Step-by-step explanation:
Let x represent the number of hours it takes the larger hose to fill the pool. Then each hour, it contributes 1/x of the pool volume. Similarly, the other hose contributes a volume of 1/(1.5x) each hour.
The two hoses together contribute a volume of 1/9 of the pool volume each hour:
1/x +1/(1.5x) = 1/9
2.5/(1.5x) = 1/9 . . . . combine the fractions
22.5/1.5 = x . . . . . . multiply by 9x
15 = x
It takes the larger hose 15 hours to fill the pool alone.

Answers and Step-by-step explanations:
1. We need to plug in values of x into the functions f(x) and g(x):
f(2) = 2.5 * 2 - 10.5 = -5.5 g(2) = [tex]64 * (0.5^2)[/tex] = 16
f(3) = 2.5 * 3 - 10.5 = -3 g(3) = [tex]64 * (0.5^3)[/tex] = 8
f(4) = 2.5 * 4 - 10.5 = -0.5 g(4) = [tex]64 * (0.5^4)[/tex] = 4
f(5) = 2.5 * 5 - 10.5 = 2 g(5) = [tex]64 * (0.5^5)[/tex] = 2
f(6) = 2.5 * 6 - 10.5 = 4.5 g(6) = [tex]64 * (0.5^6)[/tex] = 1

(a) Notice that at 14 on the x-axis, the blue line is above 4. Meanwhile, at 14, the red line is less than 2. Obviously, we can see that if the printed ad revenue was less than 2 and the online ad revenue was greater than 4, that's more than a double, so the lead marketing executive is correct.
(b) The approximate year that the revenues were equal is the place where the lines intersect. It's approximately at Year 7.5.
3.
(a) The Western Beach is clearly decreasing; it is decreasing by 2 ft per year. Meanwhile, the Dunes Beach is clearly increasing; it's increasing by 5 ft per year. (I'm not sure what kinds of "patterns" you're looking for).
(b) Year 11 and 12; this is because here, Western is going from 78 to 76 ft and Dunes is going from 75 to 80, so they'll likely coincide sometime in that time interval.
(c) One thing you can do is to create equations (of the form y = mx + b) for each of the beaches and then set those linear equations equal to each other.
Answer:
Page 1:
f(2) = -5.5
f(3) = -3
f(4) = -0.5
f(5) = 2
f(6) = 4.5
Notice the values are increasing by 2.5
g(2) = 16
g(3) = 8
g(4) = 4
g(5) = 2
g(6) = 1
Notice the values are getting divide by half
Page 2:
A:
At 14 years, the revenue for online ads are a little over 4 million dollars. However, for printed ads, the revenue is only about 1.5 million dollars. If you double 1.5 million, you will only get 3 million. That is less than 4 million. So, the lead marketing executive was correct.
B:
The approximate year that the two revenues were equal was approximately 7 and a half (or 7.5).
Page 3:
A:
For the Western Beach, the width is decreasing by exactly 2 feet per year. For the Dunes Beach, the width is increasing by exactly 5 feet per year.
B:
The beaches will have the same width somewhere between years 11 and 12.
C:
A good way to get an even better approximation on when these beaches will have the same width, is to write them in slope-intercept form. The Western Beach equation will look like f(x) = -2x + 100 and the Dunes Beach equation will look like g(x) = 5x + 20.

A car travels at a steady speed of 10 m/s what distance is covered in one minute
Answers
Answer:600
Step-by-step explanation:
There are 60 seconds in one minute so you would need to multiply 60 by 10
A car traveling at a steady speed of 10 m/s will cover a distance of 600 meters in one minute.
Explanation:The distance covered by a car moving at a steady speed can be calculated from the simple physics formula for speed: speed = distance/time. In this case, the speed of the car is given as 10 m/s, and the time is given as 1 minute. However, time needs to be in the same units as the speed, so we need to convert minutes to seconds. As one minute is equal to 60 seconds, we can use this conversion. Now, to solve for distance, we rearrange the equation to look like: distance = speed * time. Substituting the given speed and time, we get: distance = 10 m/s * 60 s = 600 m. Therefore, a car traveling at a steady speed of 10 m/s will cover a distance of 600 meters in one minute.

two trains leave the station at the same time, one heading west and the other east. the westbound train travels at 80 miles per hour. the eastbound train travels at 60 miles per hour. how long will it take for the two trains to be 392 miles apart? do not do any rounding.
Answers
Answer:
let this happens after t hours
so
80t + 60t = 392
140 t = 392
t = 392/140
=2.8 hours

There were 75 roasted turkeys at Ally's Eats. Bob's Goods had 4/5 as many roasted turkeys as Ally's Eats. If Ally's Eats had 5/6 as many roasted turkeys as Charlotte's Market what was the average number of roasted turkeys owned by each of the three shops?
Answers
Answer:
Step-by-step explanation:
Roasted turkey in Ally's Eats = 75
Roasted turkey in Bob's goods = 4 / 5 x Ally's Eats
= (4 / 5) x 75
= 60
Roasted turkey in Charlotte's Market = N ( let )
Given
5/6 N = 75
N = 6 / 5 x 75
= 90
Roasted turkey in Charlotte's Market = 90 .
To find the average number of roasted turkeys owned by each of the three shops, add up the number of turkeys owned by all three shops and divide by the number of shops. In this case, the average is 75 turkeys.
Explanation:To find the average number of roasted turkeys owned by each of the three shops, we need to calculate the total number of roasted turkeys owned by all three shops and then divide it by the number of shops.
First, we find the number of roasted turkeys owned by Bob's Goods, which is 4/5 * 75 = 60 turkeys.
Next, we find the number of roasted turkeys owned by Charlotte's Market, which is 75 / 5/6 = 90 turkeys.
Finally, we add up the number of turkeys owned by all three shops: 75 + 60 + 90 = 225 turkeys.
To find the average, we divide the total number of turkeys by the number of shops: 225 turkeys / 3 shops = 75 turkeys.
Therefore, the average number of roasted turkeys owned by each of the three shops is 75 turkeys.

A drawer contains 30 pens of various colors: 4 are black, 10 are blue, 3 are red, 6 are green, 6 are blue and red, and 1 is white
A green pen is removed from the drawer and replaced before a black pen is removed.
Answers
Answer:
2/75
Step-by-step explanation:
6 of the 30 pens are green, so the probability of selecting a green pen is 6/30 = 1/5.
The pen is then replaced, so there are still 30 pens in the drawer. 4 of the pens are black, so the probability of selecting a black pen is 4/30 = 2/15.
The probability of both events is therefore 1/5 × 2/15 = 2/75.

Using the linear combination method, what is the solution to the system of linear equations 7 x minus 2 y = negative 20 and 9 x + 4 y = negative 6?
Answers
Answer:
(- 2, 3 )
Step-by-step explanation:
Given the 2 equations
7x - 2y = - 20 → (1)
9x + 4y = - 6 → (2)
Multiplying (1) by 2 and adding to (2) will eliminate the term in y
14x - 4y = - 40 → (3)
Add (2) and (3) term by term to eliminate the term in y
23x = - 46 ( divide both sides by 23 )
x = - 2
Substitute x = - 2 into either of the 2 equations and evaluate for y
Substituting into (2)
9(- 2) + 4y = - 6
- 18 + 4y = - 6 ( add 18 to both sides )
4y = 12 ( divide both sides by 4 )
y = 3
Solution is (- 2, 3 )
The required solution of the given simultaneous equation is x = -2 and y = 3.
What are simultaneous linear equations?Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
Given equations,
7x - 2y = -20 - - - - - (1)
9x + 4y = -6 - - - - - (2)
Multiply equation 1 with 2 and add both equations,
14x - 4y + 9x + 4y = -40 - 6
23x = -46
x = -2
Now,
7(-2) - 2y = -20
-2y = -6
y = 3
Thus, the required solution of the given simultaneous equation is x = -2 and y = 3.

If f(x) = -x^2 – 1, and
g(x) = x + 5, then
g(f (x)) = -x^2+[ ?]x + [ ?]
Answers
By substituting the expression for f(x) into g(x), g(f(x)) simplifies to -x^2 + 4. The coefficient of x^2 is inherited from f(x), and the constant term changes due to the addition in g(x).
To find g(f(x)), substitute the expression for f(x) into g(x):
g(f(x)) = g(-x^2 - 1)
Now, replace x in g(x) with -x^2 - 1:
g(f(x)) = (-x^2 - 1) + 5
Combine like terms:
g(f(x)) = -x^2 + 4
So, the given expression g(f(x)) = -x^2 + 4. The coefficient of x^2 remains -1 from f(x), and the constant term changes from -1 to +4 after adding 5 in the expression g(x).
Here g(f(x)) simplifies to -x^2 + 4, where the coefficient of x^2 is inherited from f(x), and the constant term changes due to the addition in g(x).

Which do the following most specifically describes a rhombus?? A.a plane figure that is a polygon. B.a quadrilateral with 2 pairs of equal length. D. A polygon with four sides
Answers
Answer:
B. A quadrilateral with 2 pairs of equal length
Step-by-step explanation:
analyzing the options:
A. A polygon is a very general definition (polygon is a figure with 3 or more sides) so it does not specifically describe a rhombus.B. This option is much more specific to a rhombus than the other two options because it mentions that it is a quadrilateral so it reduces the generality of calling it a polygon, and it also mentions that there are 2 pairs of equal sides which is true for the rhombus (the top and bottom sides are equal, and the sides are also equal). So this option is correct.C. It is a little more specific than option A because it mentions that you must have 4 sides, but it is not as specific for the rhombus as option BAnswer:
B.a quadrilateral with 2 pairs of equal length
Step-by-step explanation:
A rhombus is a quadrilateral with 4 equal sides in length. A quadrilateral is a closed figure or shape with 4 sides . Other quadrilaterals are parallelograms, square and rectangle .
Opposite sides of a rhombus are parallel and opposite angles are equal. The diagonals meet at the center to form a right angle. The best description of a rhombus among the option is that it is a quadrilateral with 2 pairs of equal length.
Note polygon is too broad to be used to describe a rhombus .Moreover rhombus is not a regular polygon since all the angles are not equal.
