Fadi set out at 5am on his bike averaging at 6mph. At 8am Chris goes out on his moped averaging 15mph. What time will Chris catch up with Fadi?
Since at 8am Chris goes out on his moped averaging 15mph, the time Chris catches up with Fadi is at 10 am.
How to find the time will Chris catch up with Fadi?Since Fadi set out at 5am on his bike averaging at 6mph, the distance Fadi travels is d = vt where
v = Fadi's speed = 6 mph and t = time.So, Fadi's distance d = vt
= 6t
Now, At 8am Chris goes out on his moped averaging 15mph, the distance Chris travels is D = v't' where
v = Chris' speed and t = Chris' time of travel.So, Chris' distance D = v't'
= 15t'
Also, since Fadl sets out at 5 am on his bike and Chris goes out on his moped at 8 am, Chris sets out 8 am - 5 am = 3 hrs later.
So, Chris' time of travel t' = t - 3
So, Chris' distance D = 15t' = 15(t - 3)
Now, Chris will catch up with Fadi when they both cover the same distance
So, d = D
6t = 15(t - 3)
6t = 15t - 45
6t - 15t = -45
-9t = -45
t = -45/-9
t = 5 hours
Since Chris's time is t' = t - 3, substituting t = 5 into the equation, we have
t' = 5 - 3
= 2 hours
So, Chris catches up with Fadi 2 hours later at 8 am + 2 hours = 10 am.
So, the time Chris catches up with Fadi is at 10 am.

What does a math factor mean?
A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor in mathematics. As an illustration, 3 and 6 are factors of 12 because 12 3 = 4 and 12 6 = 2, respectively. 1, 2, 4, and 12 are the other components that make up 12.mx + nx = p

Given the perimeter, the length and width of the rectangular planter bed are 35ft and 11ft respectively.
What is the length and width of the rectangular planter bed?The perimeter of rectangle is expressed as;
P = 2( l + w )
Given the data in the question;
Let 'x' represent the width of the rectangle.
Width w = xLength = 3x + 2Perimeter P = 92ftPlug the given values into the above above equation.
P = 2( l + w )
92 = 2( ( 3x + 2 ) + x )
Solve the equation for x.
92 = 2( ( 3x + 2 ) + x )
92 = 6x + 4 + 2x
92 = 8x + 4
8x = 92 - 4
8x = 88

gary has just retired, and has 750000 dollars in his retirement account. the account will earn interest at an annual rate of 5 percent, compounded monthly. at the end of each month, gary will withdraw a fixed amount to cover his living expenses. gary wants his savings to last 30 years. how much money can he withdraw each month
The amount of money that Gary can withdraw each month is equal to $4026.18.
Given the following data:
Value of each payment, P = 750,000 dollars.Annual percentage interest rate, APR = 5% = 0.05.Time, t = 30 years.What is APR?APR is an acronym for annual percentage rate and it can be defined as a measure of an amount of money based on a yearly rate of interest, which a borrower must pay on a loan or credit card.
This ultimately implies that, the annual percentage rate (APR) would be calculated by dividing the rate of interest by twelve (12).
Rate of interest, r = APR/12
Rate of interest, r = 0.05/12
Rate of interest, r = 0.0041667
Next, we would calculate the present value of this ordinary annuity by using this formula:
Present value, PV = [P ÷ [1 - (1 + r)^{-nt}]/r]
Substituting the given parameters into the formula, we have;
Present value = [750,000 ÷ [(1 - (1 + 0.0041667)^{-30 × 12})/0.0041667]
Present value = [750,000 ÷ [(1 - (1.0041667)^{-360})/0.0041667]
Present value = [750,000 ÷ [(1 - 0.2238239)/0.0041667]
Present value = [750,000 ÷ [0.7761761/0.0041667]

A Mathematical fest was conducted in a school by a group of students. School's principal gave them the budget of ₹32000. They spend 1/4 of the budget on food stalls; 3/10 of the remainder on games and activities and 5/21 of the remainder on gift distribution event. How much money is still left with them?
The amount of money left with them is $12,800.
How much money is left?The first step is to determine the amount left after 1/4 of the budget is spent on food stalls.
Budget left : (1 - 1/4) x amount of budget
(1 - 1/4) x 32,000
3/4 x 32,000 = 24,000
The second step is to determine how much of the budget is left after spending on games and activities :
(1 - 3/10) x 24,000
7/10 x 24,000 = 16,800
The third step is to determine how much is left after spending the remainder on gift distribution
(1 - 5/21) x 16,800
16/21 x 16,800 = $12,800

Using function concepts, it is found that:
a) Point (3,-13) is not on the graph, because substituting x = 3 on the equation does not result in 13.
b) If x = 1, f(x) = -3, hence point (1,-3) is on the graph of f.
c) if f(x) = 2, x = 16, so point (16,2) is on the graph of f.
d) The domain is all real numbers except x = 4.
e) The x-intercept is of x = -8.
f) The y-intercept is of y = -2.
What are the points on the graph?The function is given by:
f(x) = (x + 8)/(x - 4).
Hence, when x = 3:
f(3) = (3 + 8)/(3 - 4) = 11/-1 = -11.
Hence:
Point (3,-13) is not on the graph, because substituting x = 3 on the equation does not result in 13.
When x = 1, we have that:
f(1) = (1 + 8)/(1 - 4) = 9/-3 = -3.
If x = 1, f(x) = -3, hence point (1,-3) is on the graph of f.
For f(x) = 2, we have that:
2 = (x + 8)/(x - 4)
2x - 8 = x + 8
x = 16.
Hence:
if f(x) = 2, x = 16, so point (16,2) is on the graph of f.
What is the domain of the function?The domain of a function is the set that contains all possible input values of the function.
This function is a fraction, meaning that the denominator cannot be zero, so:
x - 4 = 0 -> x = 4.
Hence:
The domain is all real numbers except x = 4.
What are the intercepts of the function?The x-intercept of a function is given by the value of x when f(x) = 0, that is, the value of x when the function crosses the x-axis.The y-intercept of a function is given by the value of f(x) when x = 0, that is, the value of y when the function crosses the y-axis.For this problem, we have that:
f(x) = 0.
(x + 8)/(x - 4) = 0.
x + 8 = 0
x = -8.
f(0) = 8/-4 = -2.
Hence:
e) The x-intercept is of x = -8.
f) The y-intercept is of y = -2.

A bakery sold 138 mocha cupcakes in a day, which was 46% of the total number of cupcakes sold that day. How many total cupcakes did the bakery sell that day?
Answer:
x=300
Step-by-step explanation:
138=46%x
x=300
hope this helps!
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
46% = 138
100% = 300
The total number of cupcakes sold on that day is 300.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of mocha cupcakes sold in a day = 138
The percentage of mocha cupcakes sold in a day = 46%
The percentage of total cupcakes sold in a day = 100%
Now,
46% = 138
Multiply 100/46.
100/46 x 46% = 100/46 x 138
100% = 300
Thus,
The total number of cupcakes sold on that day is 300.
