Answer:
48 minutes
240 at 60mph = 4 hrs.
240 at 50 mph = 4.8 hrs.
it would take an extra 60*.8 or 48 minutes
Step-by-step explanation:
The trip will be of 48 minutes longer when the speed is decreased by 10 miles per hour.
What is the formula for time?
The time is given by distance/speed. The unit of time is minutes or seconds.
What will be the time difference?When distance of 240 miles is cover by the speed of 60 miles per hour then the time take to travel this distance will be 240/60=4 hours
When distance of 240 miles is cover by the speed of 50 miles per hour then the time take to travel this distance will be 240/50=4.8 hours
The difference between 4.8 hours and 4 hours is of 0.8 hours or 0.8*60=48 minutes.
Therefore, the trip will be of 48 minutes longer.

The radius of the large sphere is times longer than the radius of the small sphere.
How many times the volume of the large sphere is the volume of the small sphere?
Help! Help! Help! Please!
Answer:
A. ¹/27
Step-by-step explanation:
✔️Volume of large sphere = ⁴/3πr³
r = 18.6 in.
Volume of large square = ⁴/3*π*18.6³ = 26954.26 in.³
✔️Volume of small sphere = ⁴/3πr³
r = 6.2 in.
Volume of small sphere = ⁴/3*π*6.2³ = 998.31 in.³
✔️Ratio of the volume of the smaller sphere to the larger sphere = 998.31 : 26954.26
= 1 : 27
Therefore, the volume of the large sphere is ¹/27 of the volume of the small sphere.

Answer:
Step-by-step explanation:
To evaluate such, the following must be comprehended:
Slope: Rise/Run.
X-intercept: The peculiar point in which the observed linear data intersects the x-axis.
Y-intercept: The peculiar point in which the observed linear data intersects the y-axis.
To evaluate for the slope, which is defined as the agglomerate distance between two points contained within linear data, the following equation must be utilized:
m = (y2 - y1) / (x2 - x1)
Points utilized or given: (-1, 2) and (7, 2).
2 - 2 / 7 + 1 = 0/8 ==> 0
Henceforth, the slope for the particular configuration, as provided, is understood as zero (0).
Utilizing the integral of one of the points provided, as well as slope evaluated for, the following equation could be exploited:
Point-Slope Formula:
Y- y1 = m(x - x1)
Y - 2 = 0(x - 7)
Y - 2 = 0
Y = 2
Hence, the answer to the peculiar interrogate is disclosed as 2, which is identified as where the horizontal line intersects the y-axis at (0, 2).

The simple interest formula is I = Prt, where I represents simple interest on an amount, P, for t years at a rate of r, where r is expressed as a decimal.
What is the amount of money, P, that will generate $40 in interest at a 10% interest rate over 5 years?
$60
$80
$90
$100
Answer:
80
Step-by-step explanation:
I = Prt
I = 40 R = .10 T = 5
40 = P (.10)(5)
40 = P(.5)
Divide each side by .5
40/.5 = .5P/.5
80 = P
The interest over 5 years is $80.
The correct option is B.
What is the simple interest?Simple interest is the borrowing amount added only to the principal amount.
The Formula to calculate the simple interest is;
S.I. = P x T x R / 100,
Where S.I. is simple interest, P is the principal amount, T is the time period and R is the interest rate in a year.
We can use the formula I = Prt to solve for P. We know that I = 40, r = 0.10, and t = 5. Substituting these values, we get:
40 = P(0.10)(5)
Simplifying:
40 = 0.5P
Dividing both sides by 0.5:
P = 80
Therefore, the amount of money, P, that will generate $40 in interest at a 10% interest rate over 5 years is $80.

DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD!!!!!!!!!!Use the given conditions to write an equations for the line in slope- intercept form. passing through (1,-8) and (-7,8)
Answer:
y = -2x - 6
Step-by-step explanation:
Going from the first point to the second, we see x decreasing by 8 from 1 to -7 (this is the 'run') and y increasing by 16 from -8 to +8 (this is the 'rise'). Thus, the slope of the line through these two points is m = rise/run = 16/(-8) = -2.
Using the point-slope formula y - k = m(x - h) and the point (1, -8), we get:
y + 8 = -2(x - 1), or
y = -8 - 2x + 2, or
y = -2x - 6 (in slope-intercept form)

Belinda is thinking about buying a house for $179,000. The table below shows the projected value of two different houses for three years:
Number of years 1 2 3
House 1 (value in dollars) 186,160 193,606.40 201,350.66
House 2 (value in dollars) 190,000 201,000 212,000
Part A: What type of function, linear or exponential, can be used to describe the value of each of the houses after a fixed number of years? Explain your answer. (2 points)
Part B: Write one function for each house to describe the value of the house f(x), in dollars, after x years. (4 points)
Part C: Belinda wants to purchase a house that would have the greatest value in 30 years. Will there be any significant difference in the value of either house after 30 years? Explain your answer, and show the value of each house after 30 years. (4 points)
There are several types of functions, but this question is limited to just 2 types, which are the exponential function and the linear function.
House 1 has an exponential function of [tex]f(x) = 179000 * 1.04^x[/tex] while house 2 has a linear function of [tex]f(x) =11000x+179000[/tex]. House 1 will have a greater value in 30 years and the difference between the values of the two houses is significant.The given parameters can be represented as:
[tex]\begin{array}{cccc}{Years} & {1} & {2} & {3} & {House\ 1} & {186,160 } & {193,606.40 } & {201,350.66} & {House\ 2} & {190,000 } & {201,000 } & {212,000} \ \end{array}[/tex]
(a): The type of function
First, we check if the function is linear by calculating the difference between each year
House 1
[tex]d = 193606.40 - 186160 = 7446.4[/tex]
[tex]d = 201350.66 - 193606.40 = 7744.26[/tex]
The difference are not equal; hence, the function is not linear. So, we can assume that it is exponential
House 2
[tex]d = 201000 - 190000 =11000[/tex]
[tex]d = 212000 - 201000 =11000[/tex]
The difference are equal; hence, the function is linear.
(b): The function of each
House 1
An exponential function is represented as:
[tex]y = ab^x[/tex]
When [tex]x = 1;\ y =186,160[/tex]
We have:
[tex]186,160 =ab^1[/tex]
[tex]186,160 =ab[/tex] ---- (1)
When [tex]x = 2;\ y =193606.40[/tex]
We have:
[tex]193606.40 =ab^2[/tex] --- (2)
Divide (2) by 1
[tex]\frac{193606.40}{186160} =\frac{ab^2}{ab}[/tex]
[tex]1.04 = b[/tex]
[tex]b = 1.04[/tex]
Make a the subject in (1)
[tex]186,160 =ab[/tex]
[tex]a = \frac{186160}{b}[/tex]
[tex]a = \frac{186160}{1.04}[/tex]
[tex]a = 179000[/tex]
So, the function for house 1 is:
[tex]f(x) = 179000 * 1.04^x[/tex]
House 2
A linear function is represented as:
[tex]y = mx + b[/tex]
First, we calculate the slope (m)
[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]
So, we have:
[tex]m = \frac{201000 - 190000}{2 - 1}[/tex]
[tex]m = \frac{11000}{1}[/tex]
[tex]m = 11000[/tex]
So, the equation is:
[tex]y =m(x-x_1) + y_1[/tex]
Substitute known values
[tex]y =11000(x-1) + 190000[/tex]
[tex]y =11000x-11000 + 190000[/tex]
[tex]y =11000x+179000[/tex]
So, the function for house 2 is:
[tex]f(x) =11000x+179000[/tex]
(c): House with the greatest value in 30 years
This means that:
[tex]x = 30[/tex]
For house 1, we have:
[tex]f(x) = 179000 * 1.04^x[/tex]
[tex]f(30) = 179000 * 1.04^{30}[/tex]
[tex]f(30) = 580568.15[/tex]
For house 2, we have:
[tex]f(x) =11000x+179000[/tex]
[tex]f(30) = 11000 * 30+ 179000[/tex]
[tex]f(30) = 509000[/tex]
By comparison;
[tex]580568.15> 509000[/tex]
House 1 will have a greater value in 30 years
And the difference between the values is significant
The difference is:
[tex]d =580568.15-509000[/tex]
[tex]d =71568.15[/tex]

Consider the function, y = - 13x +52. Find the inverse of the function by solving it for
x. Then, use the inverse to find a value of y such that x = 182.
Answer:
The customary method of finding the inverse is some variant of the method I'm going to use below. Whatever method you use, make sure you do the exact same steps in the exact same order every time, so you remember those steps when you get to the test.
Find the inverse of y = 3x – 2.
Here's how the process works:
Here's my original function:
y = 3x - 2
Now I'll try to solve for "x =":
y + 2 = 3x
(y + 2)/3 = x
Once I have " x =", I'll switch x and y; the "y =" is the inverse.
y = (x + 2)/3
Then the inverse is y = (x + 2) / 3
If you need to find the domain and range, look at the original function and its graph. The domain of the original function is the set of all allowable x-values; in this case, the function was a simple polynomial, so the domain was "all real numbers". The range of the original function is all the y-values you'll pass on the graph; in this case, the straight line goes on for ever in either direction, so the range is also "all real numbers". To find the domain and range of the inverse, just swap the domain and range from the original function.
