Answer:
After 4 days, the temperature will be 3/4 Fahrenheit degrees lower than today
Step-by-step explanation:
Let's calculate the change in temperature after 4 days, this way:
Today's temperature = t in Fahrenheit degrees
Tomorrow's temperature = t - 3/16 Fahrenheit degrees
The day after tomorrow's temperature = t - 2 * 3/16 = t - 3/8 Fahrenheit degrees
Therefore, the temperature after 4 days will be = t - 4 * - 3/16 = t - 3/4 Fahrenheit degrees
After 4 days, the temperature will be 3/4 Fahrenheit degrees lower than today

Type your answer as a decimal.
pages per hour.
Answer: [tex]0.8[/tex] pages per hour.
Step-by-step explanation:
For this exercise it is important to know that, by definition, Direct variation equations have the following form:
[tex]y=kx[/tex]
Where "k" is the constant of variation.
Therefore, it is a straight line that passes through the origin.
In this case, given the graph attached in the exercise, you can follow these steps in order to find the constant of variation:
Step 1: You need to choose any point on the line. Let's choose the point (5,4).
Step 2: Now you must ubstitute the coordinates of that point into [tex]y=kx[/tex]. Then:
[tex]4=k(5)[/tex]
Step 3: Finally, you must solve for the Constant of variation "k", in order to find its value. Therefore, you get that this is:
[tex]k=\frac{4}{5}\\\\k=0.8[/tex]

Write the equation of a line that contains (2,-4) and that is perpendicular to y=2/3x+2
Answer:
y = - [tex]\frac{3}{2}[/tex] x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{2}{3}[/tex] x + 2 ← is in slope- intercept form
with slope m = [tex]\frac{2}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{2}{3} }[/tex] = - [tex]\frac{3}{2}[/tex], thus
y = - [tex]\frac{3}{2}[/tex] x + c ← is the partial equation
To find c substitute (2, - 4) into the partial equation
- 4 = - 3 + c ⇒ c = - 4 + 3 = - 1
y = - [tex]\frac{3}{2}[/tex] x - 1 ← equation of perpendicular line

4/5 is greater than less then or equal to 1/2
Greater Than!
First make the denominator (the bottom number) the same for both fractions. So you can multiply the 1/2 by 5 and the 4/5 by 2.
This will make them 5/10 and 8/10.
Then, you see that 8/10 (4/5) is greater than 5/10 (1/2)
Hope that’s makes sense! :)
The fraction 4/5 is greater than 1/2. This conclusion can be reached by converting the fractions to decimal form, where 4/5 becomes 0.8 and 1/2 becomes 0.5, highlighting that 0.8 is indeed greater than 0.5.
Explanation:The question is whether the fractional value of 4/5 is greater than, less than, or equal to 1/2. To compare these fractions, it may be helpful to first convert them to decimal form, as this is often easier to understand than comparing fractions directly. 4/5 as a decimal is 0.8 and 1/2 as a decimal is 0.5. Hence, 0.8 is greater than 0.5. Therefore, 4/5 is greater than 1/2.

For which values of A, B, and C will Ax + By = C be a vertical line through the point (8, 6)
Answer:
Step-by-step explanation:
a vertical line has an undefined slope....(8,6).....its equation is x = 8 because no matter what y is, x will always be 8.
but u need it in standard form Ax + By = C
so it is written as : x + 0y = 8 <===
A = 1
B = 0
C = 8
Ax + By = C will be a vertical line passing through point (8,6) for values of A = 1 , B = 0 and C = 8.
What is a vertical line ?
In a coordinate plane, a line parallel to the Y-axis is called vertical Line. Any point in this line will have the same value for the x-coordinate.
We know that the x-axis has lines that run vertical then if you have a point use your x-ordinate.
The equation of a vertical line is :
x = C
here : C is the value of the x- coordinates the line passes through.
In the given question we have to find out the values of A , B and C for which Ax + By = C be a vertical line passing through point (8,6).
Here , the coordinate of point (x , y) is (8 , 6).
So , the equation of vertical line will be x = 8.
So , if we compare it with the general form of line , Ax + By = C, then we get :
8A + By = 8
So , values of A , B and C :
A = 1, B = 0, C = 8
Therefore , Ax + By = C will be a vertical line through point (8,6) for values of A = 1 , B = 0 and C = 8.

Seth’s father is thinking of buying his son a six-month movie pass for $40. With the pass, matinees cost $1.00. If matinees are normally $3.50 each, how many times must Seth attend in order for it to benefit his father to buy the pass?
Answer:
In order for it to benefit his father to buy the pass Seth have to attend the movies for 11 times.
Step-by-step explanation:
Given:
Cost of movie pass = $40
Cost per matinees with pass = $1.00
Cost per matinees without pass = $3.50
To Find:
Number of times must Seth attend in order for it to benefit his father to buy the pass = ?
Solution:
Let x be the number of times he wants to visit
To profit his father
The number of visits without pass = the number of visits with passin the cost of $3.50
Then, without pass if he visits for x times then the cost will be = 3.50x
Also with pass, the number of times he can visit the pass = [tex]\frac{40}{3.50}[/tex]

A total of $30,000 is invested in two corporate bonds that pay 5.5% and 6.25% simple interest. the investor wants an annual interest income of %1800 from the investments. what is the most that can be invested in the 5,5% bond?
Answer:
$10,000
Step-by-step explanation:
Let x represent the amount invested in the 5.5% bond.
For an annual income of $1800, we want ...
(5.5%)x + (6.25%)(30,000-x) = 1800
(-0.75%)x + 1875 = 1800
-0.0075x = -75 . . . . . . . . . subtract 1875
x = 10,000 . . . . . . . . . . . . . divide by -0.0075
At most $10,000 should be invested at 5.5% to obtain at least $1800 in interest.
When 238 is divided by the natural number n, the quotient is 3 more than n, and there is no remainder. What is n?
Answer:
n = 14
Step-by-step explanation:
Write the equation in algebraic (numbers and symbols) form
[tex]\frac{238}{n}[/tex] = n + 3 Rearrange the equation
[tex]n\frac{238}{n}[/tex] = n(n + 3) Multiply both sides by 'n'
238 = n(n + 3) On the left, multiplying and dividing by 'n' cancels out
238 = n² + 3n Distributed right side
0 = n² + 3n - 238 Rearranged to standard form for quadratic equations
Remember standard form for quadratic equations is: ax² + bx + c = 0
State the variables a, b and c:
a = 1; b = 3; c = -238
When a quadratic equation is in standard form, you can use the quadratic formula to solve for 'n'. (Usually, you see the variable 'x', but the quadratic formula can solve for 'n' as if it is 'x', as long as it's in standard form.)
[tex]n = \frac{-b±\sqrt{b^{2}-4ac}}{2a}[/tex] (ignore the Â, it's a formatting error)
[tex]n = \frac{-(3)±\sqrt{(3)^{2}-4(1)(-238)}}{2(1)}[/tex] Substitute the values for 'a', 'b' and 'c' from the equation
[tex]n = \frac{-3±\sqrt{9-(-952)}}{2}[/tex] In the root, two negatives make a positive
[tex]n = \frac{-3±\sqrt{9+952}}{2}[/tex] Add inside the root
[tex]n = \frac{-3±\sqrt{961}}{2}[/tex] Find the square root of 961
[tex]n = \frac{-3±{31}{2}[/tex] Split the equation at the ±
Split for adding:
[tex]n = \frac{-3+31}{2}[/tex] Simplify
n = 14
Split for subtracting:
[tex]n = \frac{-3-31}{2}[/tex] Simplify
n = -17
You get the answers 14 and -17 for 'n'. Decide which one is 'inadmissible', meaning it can't be right even if it solves the equation.
The problem says 'n' is a natural number. Natural numbers are all non-partial numbers count up from 1. (Non-partial means as a fraction, they are reduced to a number over 1). Since -17 is less than 1, it is inadmissible because it is not a natural number.
Therefore, 'n' is 14.

25. Belle had the choice of taking out a 4-year car loan at
8.5% simple interest or a 5-year car loan at 7.75%
simple interest. If she borrows $15,000, how much
interest would she pay for each loan? Which option
will require less interest?
Answer:
the first loan is cheaper
Step-by-step explanation:
convert percent values to decimals
8.5/100=.085
7.75/100=.0775
find the value for the first loan
1550*.085*4=527
find the value for the first loan
1550*.0775*5=600.625
compare
Belle would pay $5100 in interest for the 4-year loan at 8.5% and $5812.50 for the 5-year loan at 7.75%. Therefore, less interest would be paid with the 4-year loan.
Explanation:To calculate the simple interest, we use the formula I = P*R*T, where P is the principal amount, R is the interest rate, and T is the time in years.
For the 4-year loan at 8.5%, interest would be: I = $15,000 * 8.5/100 * 4 = $5100
For the 5-year loan at 7.75%, interest would be: I = $15,000 * 7.75/100 * 5 = $5,812.50.
So, the 4-year loan at 8.5% will require less interest payment.

the sum of the 5th term of the 7th term of an ap is 52 and the 10th term is 46 find the AP
Answer:
The AP is, 1 , 6, 11, 16, 21, 26, 31, .....................
Step-by-step explanation:
From the question;
Sum of fifth term and 7th term is 52 That is; 5th term + 7th term = 5210th term is 46We are required to find the AP;
We need to know that in an AP ;nth term = a + (n-1) d , where a is the first term and d is the common difference
Therefore, In this case;5th term = a + 4d
7th term = a + 6d
Therefore;5th term + 7th term = 2a + 10d = 52 ..........eqn 1
10th term = a + 9d
Thus, a + 9d = 46 ............. eqn 2We can solve eqn 1 and eqn 2 simultaneously to get the value of a and d2a + 10d = 52
a + 9d = 46
Multiplying the second equation by 2, we get;
2a + 10d = 52
2a + 18d = 92
Eliminating a by subtracting the two equations; we get;
-8d = -40
d = 5
Solving for a
a + 9d = 46
a = 46 - 9d
= 46 - 9(5)
= 46 - 45
a = 1
Thus, the first term, a= 1 and the common difference, d= 5
Therefore;
First term = a = 1
Second term = a + d = 1 + 5 = 6
Third term = a + 2d = 1 + 2(5) = 11
Fourth term = a + 3d = 1 + 3(5) =16
Fifth term = a + 4d = 1 + 4(5) = 21
Sixth term = 1 + 5d = 1 + 5(5) = 26
Seventh term = 1 + 6d = 1 + 6(5) = 31
Thus,
The AP is, 1 , 6, 11, 16, 21, 26, 31, .....................

How do we solve for “p”, when
P= 75 + 45h
Answer:
See below.
Step-by-step explanation:
The equation is already solved for p.
p = 75 + 45h
Final answer:
To solve for the fluid density 'p', use the hydrostatic pressure formula P = pgh. By rearranging the formula to p = P / (gh) and inputting the known values for P (atmospheric pressure) and h (height of the water column), the density can be calculated.
Explanation:
To solve for density 'p' when given the equation P = 75 + 45h, where P represents atmospheric pressure and h is the height of a column of fluid, we need to incorporate the concept of hydrostatic pressure. The formula for hydrostatic pressure is P = pgh, where 'p' is the fluid density, 'g' is the acceleration due to gravity, and 'h' is the height of the fluid column. If we know the value of 'P' and the value of 'h', we can isolate 'p' by rearranging the equation to p = P / (gh). This calculation assumes that 'g', the acceleration due to gravity, is a known constant.
Let's assume 'P' is given as 1.00 atm (standard atmospheric pressure) for a water column which is the fluid we're working with. The density 'p' of water that creates this pressure can be calculated by inserting the known values into the expression for 'h'. For instance, if 'h' is 10 meters, the equation would be p = 1.00 atm / (9.81 m/s² × 10 m). To get 'p' in appropriate units, we would convert atm to pascals, and the result will provide the density in kg/m³.
Two weeks in a row, the golf course hosts a group of golfers. The second week had 10 more golfers than the first week. Use the dot plots to choose the true statement.
A. The range for Week 1 equals the range for Week 2.
B. The range for Week 1 is greater than the range for Week 2.
C. The median for Week 1 is less than the median for Week 2.
D. The mean for Week 1 is greater than the mean for Week 2.
Answer:
The true statement is: A. The range for Week 1 equals the range for Week 2.
Step-by-step explanation:
Let's recall that the range of a data set is the difference between the largest number and the smallest number.
As we can confirm in the plot for week 1, the range is:
Range for week 1 = Largest number - smallest number
Range for week 1 = 89 - 62 = 27
In the same way, we can confirm in the plot for week 2 that the range is:
Range for week 2 = Largest number - smallest number
Range for week 2 = 89 - 62 = 27
Ranges for week 1 and 2 are equal, thus,
The true statement is: A. The range for Week 1 equals the range for Week 2.
