Two friends race. The first friend gets a head start and runs at a steady rate of 0.20 miles per minute. The second friend waits 1 minute and then runs at a steady rate of 0.25 miles per minute. How long will it take for the second runner to catch up with the first?
Step-by-step explanation:
In this problem we are expected to solve for the time taken for the second person to meet with the first.
given that
first person's speed=0.2mph
let time taken be= x
we know that
velocity= distance/time
0.2=distance/x
distance=0.2x----1
second person's speed= 0.25mpm
time taken=x-1
we know that
velocity= distance/time
0.25=distance/x-1
distance=0.25(x-1)
distance=0.25x-0.25-----2
equating equation 1 and 2 we have
0.2x=0.25x-0.25
0.2x-0.25=-0.25
-0.05x=-0.25
divide both sides by -0.05 we have
x=-0.25/-0.05
x=5
we know that the second person's time is described by
=x-1
=5-1=4min
The second person will catch up after 4 minutes
ce is the angle bisector of dcb and m
Answer:
We are given that ray CE is an angle bisector of angle ACD. With this, we have the equation,
mACE = mECD
Next, we look at the choices
mECD = mECB > This not possible since ray CD is between the two angles
mACE = mACD > This is still not possible since ray CE is between the two angles
mACE = mDCB > This is possible since angles ACE, ECD and DCB are complementary angles.
mECD = mACD > This is not possible since ray CE is between the two rays

125x^3+343y^3
Answer:
(5x + 7y)(25x² - 35xy + 49y²)
Step-by-step explanation:
125x³ + 343y³ ← is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b³) , thus
125x³ + 243y³
= (5x)³ + (7y)³
= (5x + 7y)((5x)² - 5x(7y) + (7y)² )
= (5x + 7y)(25x² - 35xy + 49y²)

A theater company charges $5.50 per ticket for people of all age groups. If c represents the total number of children who brought tickets and a represents the total number of adults who bought tickets, which expression best represents the total money earned by the company from the sale of tickets?
Answer:
[tex]5.50c+5.50a[/tex]
Step-by-step explanation:
Cost of 1 ticket = $5.50
Total number of children who brought tickets = c
Total number of adults who bought tickets = a
Amount earned from selling tickets to children = 5.50 c
Amount earned from selling tickets to adults = 5.50 a
Therefore,
Total money earned by the company from the sale of tickets = [tex]5.50c+5.50a[/tex]
A number x is twice its reciprocal. What is x^6?
Answer:
8
Step-by-step explanation:
x = 2/x <=== It must be: x ≠ 0. Solve for x. Multiply both sides by x.
x^2 = 2.
Hence:
x = ±√2.
Both -√2 and √2 give 8 when they are raised to the power of 6.
(-√2)^6 = (√2)^6 = 8.
The value of the given expression [tex]x^6[/tex] is 8 and this can be determined by using the arithmetic operations.
Given :
A number x is twice its reciprocal.
The following steps can be used in order to determine the value of [tex]x^6[/tex]:
Step 1 - The arithmetic operations can be used in order to determine the value of [tex]x^6[/tex].
Step 2 - The mathematical expression of the given statement "A number x is twice its reciprocal" is:
[tex]x = \dfrac{2}{x}[/tex]
Step 3 - Simplify the above expression in order to determine the value of 'x'.
[tex]x = \pm\sqrt{2}[/tex]
Step 4 - Now, substitute the value of 'x' in the given expression.
[tex]x^6= (\sqrt{2} )^6\\x^6 = 8[/tex]
So, the value of the given expression [tex]x^6[/tex] is 8.

Einstein once developed the formula, E = mc2, to describe the theory of relativity, where E is the total energy in the system, m is the total mass, and c2 is the speed of light. If the equation was to be rearranged in order to solve for the total mass, which formula below should be used?
A - m = E/c2
B - m = E — c2
C - m = Ec2
D - m = E + c2
Answer:
The formula which should be used is [tex]m=\frac{E}{c^{2}}[/tex] ⇒ A
Step-by-step explanation:
To solve an equation of different variables to one of these variables do that
Write the equation and underline the variable you want to solve for itSeparate this variable on one side and all other terms on the other sidesLet us do that with the question
∵ E = mc²
→ E is the total energy
→ m is the total mass
→ c² is the speed of light
∵ We need to solve the equation for the total mass m
→ We need to take c² to the other side
∵ c² is multiplied by m
∴ Divide both sides by c² to move it from the right side to the left side
∴ [tex]\frac{E}{c^{2}}=\frac{mc^{2}}{c^{2}}[/tex]
→ Cancel c² with c² on the right side
∴ [tex]\frac{E}{c^{2}}=m[/tex]
→ Switch the two sides
∴ [tex]m=\frac{E}{c^{2}}[/tex]
The formula which should be used is [tex]m=\frac{E}{c^{2}}[/tex] ⇒ A

At a fast food restaurant, customers are asked if they want to “round up” their bill to the next highest dollar and donate the additional money to charity. The cashier is instructed to tell the customer that their bill is X dollars and Y cents. Assume that the values of Y are equally likely to be any value from 0 to 99 cents and that customers are equally likely to “round up” regardless of the amount of their bill. The density curve below models Y, the donation amount. (a) What is the shape of the distribution of donations? (b) What proportion of donations are at least 85 cents? (c) What percent of donations are between 30 and 40 cents?
Answer:
(a) 0.1414
(b) 0.1010
Step-by-step explanation:
(a)
The density curve is rectangular in shape.
This implies that the distribution of donations is Uniform.
(b)
Compute the probability of donations at least 85 cents as follows:
[tex]P(X\geq 85)=\int\limits^{99}_{85} {\frac{1}{99-0} \, dx[/tex]
[tex]=\frac{1}{99}\times [x]^{99}_{85}\\\\=\frac{99-85}{99}\\\\=0.1414\\\\[/tex]
Thus, the proportion of donations that are at least 85 cents is 0.1414.
(b)
Compute the probability of donations between 30 and 40 cents as follows:
[tex]P(30\leq X\leq 40)=\int\limits^{40}_{30} {\frac{1}{99-0}} \, dx[/tex]
[tex]=\frac{1}{99}\times [x]^{40}_{30}\\\\=\frac{40-30}{99}\\\\=0.1010[/tex]
Thus, the probability of donations between 30 and 40 cents is 0.1010.
