Tourists covered 255 km for a 4-hour ride by car and a 7-hour ride by train. What is the speed of the train, if it is 5 km/h greater than the speed of the car?
[tex]\\ \text{Let the speed of the car is x km/h}\\ \text{Then, the speed of the train is x+5 km/hr}\\ \text{Now, 4 hr is the time of the car}\\ \text{and 7 hour is the time of the train}\\ \text{We know the formula}\\ \text{Distance }= \text{Velocity }\times \text{ time}\\ \text{Distance travelled by car is 4x}\\ \text{Distance travelled by train is }7(x+5)\\ \text{The total distance is given by 255 km. Hence, we have}\\ 4x+7(x+5)=255\\ 4x+7x+35=255\\ 11x=220\\ x=20[/tex]
The speed of the car is 20 km/hr and hence the speed of the train is 2+5=25 km/hr.
The speed of the train is given by 25 km/hr.
Karen is considering taking out a 20-year loan with monthly payments of $260 at an APR of 5.5%, compounded monthly, and this equates to a loan of $37,796.89. Assuming that the APR and the length of the loan remain fixed, which of these is a correct statement?
The correct statement is A;If Karen monthly payment $260 the amt of the loan that he is considering taking out would be less than $37,796.89
How to calculate EMI?The EMI formula is :
[tex]\dfrac{pr(1 + r)^n}{(1 + r)^n - 1}[/tex]
Where r = 5.5/12/100 = 0.00425
p = 37,796.89
and n = 20 x 12 = 240
Putting the values in formula we get'
= (37,796.89x 0.00425 x 2.767)/1.767
= $350
Hence,
The correct statement is A; If Karen monthly payment $260 the amt of the loan that he is considering taking out would be less than $37,796.89

A car is traveling at 48 miles per hour. What is the speed of the car in centimeters per second? (1 mile = 5,280 feet, 1 foot = 12 inches, 1 centimeter = 0.39 inch)
A car is traveling at 48 miles per hour. What is the speed of the car in centimeters per second? (1 mile = 5,280 feet, 1 foot = 12 inches, 1 centimeter = 0.39 inch)
Solution:
We have 48 [tex] \frac{miles}{hour} [/tex]
To convert, miles to centimeters.
Let us convert miles to feet and then inches and then centimeters.
1miles=5280feet
And, 1 foot=12inches
So, 5280 feet or 1 miles =12*5280inches
So, 1miles=63360inches
Now, Let us convert inches to centimeters
1centimeter=0.39inches
Or, 1 inch= [tex] \frac{1}{0.39} [/tex] centimeter
So, 63360inches (or 1 mile)= [tex] \frac{63360}{0.39} [/tex] centimeter
1mile or 63360inches=162461.54centimeter
1mile=162461.54 centimeter
We have, 48 [tex] \frac{miles}{hour} [/tex]
We have, 48 *[tex] \frac{162461.54 centimeter}{60minutes} [/tex]
We have, 48* [tex] \frac{162461.54 centimeter}{60*60seconds} [/tex]
So, We have, 48* [tex] \frac{162461.54 centimeter}{3600seconds} [/tex]
=48*[tex] \frac{162461.54}{3600} [/tex][tex] \frac{centimeters}{second} [/tex]
=48*45.13[tex] \frac{centimeters}{second} [/tex]
=2166.15[tex] \frac{centimeters}{second} [/tex]
Answer:= Speed of the car in centimeters per second is 2166.15 centimeters/second

If p(x) = 2x^3 - 3x + 5, what is the remainder of p(x) divided by (x - 5)
Final answer:
Using the Remainder Theorem, after substituting 5 into the polynomial p(x), we find that the remainder when p(x) is divided by (x - 5) is 240.
Explanation:
To find the remainder of p(x) divided by (x - 5), we can use the Remainder Theorem. The Remainder Theorem states that the remainder of a polynomial p(x) divided by (x - a) is p(a). Thus, we need to evaluate p(5).
Let's substitute x with 5 in the polynomial p(x):
p(5) = 2(5)^3 - 3(5) + 5
= 2(125) - 15 + 5
= 250 - 15 + 5
= 240.
Therefore, the remainder when p(x) is divided by (x - 5) is 240.

Which graph would help solve the equation 5log(x+3)=5
The value of x is 7 for the given equation.
What is logarithm?Logarithm, a mathematical concept involving multiplication. It is the exponent or power to which a base must be raised to yield a given number.
For the given situation,
The equation is 5log(x+3)=5.
On solving this equation, we can get value of x.
⇒ [tex]5log(x+3)=5[/tex]
⇒ [tex]log(x+3)=1[/tex]
We know that, log 10 = 1
Then,
⇒ [tex]log(x+3)=log10[/tex]
⇒ [tex]x+3=10[/tex]
⇒ [tex]x=7[/tex]
Hence we can conclude that the value of x is 7 and the graph fro the logarithmic equation is shown below.

Step-by-step explanation:
the probability of winning the game is 7/10. What is the probability that they will lose?
The probability of losing the game is 3/10 or 0.3 when the probability of winning is 7/10, because the total probability must always equal 1.
If the probability of winning the game is 7/10, then the probability of losing the game is the complement of the probability of winning. This means we subtract the probability of winning from 1. Therefore, the probability of losing the game is 1 - 7/10 = 3/10 or 0.3. This is because the sum of the probabilities of all possible outcomes in a probability distribution must equal 1.
