Trey drove 315 miles in 5 hours.
At the same rate, how many miles would he drive in 11 hours?
Within 5 hours, Trey covered 315 miles. He would need to travel 504 miles in 11 hours at the same speed.
How to calculate speed?Speed exist calculated as distance times speed. You need to be aware of the units for distance and time in order to calculate the units for speed. The units in this example will be metres per second (m/s), since the distance is measured in metres (m) and the time is measured in seconds (s). Speed (or rate, r) is a scalar number that represents the amount of time (Δt) spent traveling over the distance (d), as shown by the equation r = d/Δt.In order to compute speed, the distance traveled must be divided by the amount of time spent traveling.You must ascertain the unit rate. Divide the miles by the hours to arrive at that.
The unit rate should be found to be 63 miles per hour.
You need to double that by 8 (because it takes 8 hours),
Which is 504 miles.

how to prove 431 divides 2^43 -1
By using Fermat's Little Theorem, we were able to prove through a series of mathematical steps that 431 divides 2⁴³⁻¹
In mathematics, proving that a number divides another number means finding out if it can evenly divide the other number with no remainder.
Here we need to prove that 431 divides 2⁴³⁻¹, we can use the mathematical property of modular arithmetic.
In modular arithmetic, we are interested in finding the remainder when a number is divided by another number.
In this case, we want to find the remainder when 2⁴³⁻¹ is divided by 431.
If the result is 0, then we can conclude that 431 divides 2^43 -1.
In order to do this, we can use Fermat's Little Theorem.
Since 431 is a prime number, we can use Fermat's Little Theorem to calculate
=> 2⁴³⁰ mod 431.
If the result is 1, then we know that
=> 2⁴³ mod 431
=> 2^(43 mod 430) * 2⁴³⁰ mod 431 = 2³ mod 431.
Finally, we can calculate 2³ mod 431 and if the result is 1, we can conclude that
=> 2⁴³⁻¹ mod 431 = 1.
This means that 2 is divisible by 431 with no remainder, so we can conclude that 431 divides 2⁴³⁻¹.

What is surface area of rectangular prism?The surface area of a rectangular prism is the overall region or area that is covered by all of its faces. A three-dimensional shape is a rectangular prism. It has six faces, each of which is rectangular in shape. Consequently, a rectangular prism's two bases must likewise be rectangles.
The surface area of the rectangular prism is given by the formula:
A = 2(wl + hl + hw)
Substitute the value of A = 148, l = 4 and w = 5:
148 = 2((5)(4) + (4)h + (5)h)

a fully amortizing mortgage is made for $136,000 at 6.5 percent interest. required: if the monthly payments are $1,180 per month, when will the loan be repaid
The loan will be (ln(Time) - ln(136,000) + ln(1,180)) / ln(1 + 6.5 / 12) repaid.
What is interest ?
Interest is payment from a borrower or deposit-taking financial institution to a lender or depositor of an amount above repayment of the principal sum, at a particular rate.
Time = Loan Amount * (1 + Interest Rate / 12)^(12 * Number of Payments) / Monthly Payment
Given the loan amount ($136,000), interest rate (6.5%), and monthly payment ($1,180), we can plug these values into the formula:
Time = 136,000 * (1 + 6.5 / 12)^(12 * Number of Payments) / 1,180
To find the number of payments, we need to take the natural logarithm of both sides:
ln(Time) = ln(136,000 * (1 + 6.5 / 12)^(12 * Number of Payments) / 1,180)
ln(Time) = ln(136,000) + ln((1 + 6.5 / 12)^(12 * Number ofPayments)) - ln(1,180)
ln(Time) = ln(136,000) + 12 * Number of Payments * ln(1 + 6.5 / 12) - ln(1,180)
Next, we can isolate the number of payments on one side:
12 * Number ofPayments * ln(1 + 6.5 / 12) = ln(Time) - ln(136,000) + ln(1,180)
The loan will be (ln(Time) - ln(136,000) + ln(1,180)) / ln(1 + 6.5 / 12) repaid.

What is inequality?
Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare two values. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign in between. Sometimes it can be about a "not equal to" relationship, where one thing is more than the other or less than. In mathematics, an inequality is a relationship that results in a non-equal comparison between two numbers or other mathematical expressions.
The given inequality is y =3/5x +1
Now subtract 1 from both sides y-1 = 3/5x

The dimensions of the square are √2n by √2n
How to determine the dimensions of the squareLet's call the number of 1-blocks required to form a square "n".
The dimensions of the square can be represented as x^2 + x * (2 * n / x)
This is so because:
Each x^2 block represents a side length of x units. So, to form a square, x^2 blocks would represent x units on both sides, or x^2 units in total.Each x block represents a side length of 1 unit. To form the other two sides of the square, we need 2n/ x x blocks, each representing 1 unit, for a total of 2n units.So, we have a total of x^2 + x * (2n/x)Since the square is a perfect square, both sides of the equation must be equal:
x^2 = x * (2 * n / x)
Solving for x:
x^2 = 2n
Take the square root of both sides
x = √2n

If Caron gives $75, he will get $21 as a change, when he buys a constellation display.
To estimate the amount of change Caron will get back, we need to calculate the total cost of the two-sided tape and the star stickers. The two-sided tape costs $12 and Caron wants to buy 3 packs of star stickers which cost $14 each, so the total cost of the star stickers is 3 * $14 = $42.

This confirms that y(x) = x^c * x^(-2) is indeed a solution of the differential equation xy' + 2y = 3x.
To find the value of c so that y(1) = 5, we need to substitute x = 1 and y = 5 into the solution y(x) = x^c * x^(-2):
y(1) = 1^c * 1^(-2) = 5
1^c = 5 * 1^2 = 25
c = log_1(25)
c = log_10(25) / log_10(1) = log_10(25)
So, c = log_10(25) is the value of c that makes y(1) = 5.

what is the area of the shaded portion in the figure? If, it is a square and the lines are parts of a circle and the side of the square is 10 unit. Give answers in terms of pi.
The area of the shaded part is 50(2-π)
What is area?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
The area of the shaded part = area of a square - area of a semi circle
area of square = l× l = 10 × 10 = 10²
=100 squared units
the area of the semi circle = πr²/2
= π ×10²/2
= 50π

find the value of m for which the simultaneous equations 3x my = 5 (m 2)x 5y = m a have infinitely many solutions b have no solution.
In the simultaneous equations the value of m is 3 and the equation have many solution.
The term called equation in math is known as a condition on a variable (or variables) such that two expressions in the variable have equal value.
Here we have know that the general solution is calculated as,
=> x = (m-5)/(m-3)
and
=> y = 2/(m-3)
When we equate the equations then we get,
=> (m - 5) / (m -3) = 2/(m - 3)
=> m - 5 = 2
=> m = 3
So this dependent system has infinitely many solutions.
When m=3 the equations become look like 3x+3y=5 and 5x+5y=3.

A tree that is 12 feet tall is growing at a rate of 2 1/2
feet each year. A tree that is 15 feet tall is growing at a rate of 1 foot each year.
Enter the number of years it will take the two trees to reach the same height.
HELP please
The number of years taken for the tree to reach the same height found using mathematical expression is 2 years.
What is an expression?
Mathematical statements are called expressions if they have at least two terms that are related by an operator and contain either numbers, variables, or both. Addition, subtraction, multiplication, and division are all possible mathematical operations.
Let x be the number of years taken to reach the same height.
Height of the first tree after x years,
12 + 2.5(x)
Height of the second tree after x years,
15 + 1(x)
Given that both heights are the same after x years.
So,
12 + 2.5x = 15 + x
1.5x = 3
x = 2
Therefore the number of years taken for the tree to reach the same height is 2 years.

The alternating current in an electric inductor is I = E/Z , where E is the voltage and Z = R+XLi is impendance. If E = 7(cos 50 degrees +i sin 50 degrees), R=6, and XL=4, find the current.
The value of the current 'I' for the given relation of current , impedance, and voltage I = E/ Z is equal to I = ( 4.5 + 5.4i ) / ( 6 + 4i ).
Here R=6, and XL=4
Impedance Z = R+ XL i
⇒ Z = 6 + 4i __(1)
Where
E = 7(cos 50 degrees +i sin 50 degrees)
Simplify the above expression to get the value of voltage E.
⇒ E = 7 ( 0.6428 + i 0.7660 )
⇒ E = 4.4996 + i( 5.362 )
⇒ E = 4. 5 + 5.4i ____(2)
Now alternating current ,
I = E / Z
Substitute the value of E and Z from (1) and (2) we get,
⇒ I = ( 4.5 + 5.4i ) / ( 6 + 4i )
Therefore, the value of the current I is equal to ( 4.5 + 5.4i ) / ( 6 + 4i ).

Which substitution should best be used in solving the recurrence T(n) = 5T(4n/3) + 2?a) n = (3/4)^kb) n = (4/3)^kc) n = (15/4)^kd ) n = (20/3)^ke) n = (3/20)^kf ) n = (3/15)^kg ) n = 2^kh ) n = 3^ki ) n = 4^kj ) n = 5^k
The substitution that should best be used in solving the recurrence T(n) = 5T(4n/3) + 2 is "n = (4/3)^k".
The idea behind choosing a substitution for a recurrence relation is to simplify the relation and make it easier to solve. In this case, we want to simplify T(4n/3) to something involving T(n). By setting n = (4/3)^k, we can rewrite T(4n/3) as T((4/3)^(k+1)).
This substitution allows us to express T(4n/3) in terms of T(n) and simplify the relation.
T(n) = 5T(4n/3) + 2
becomes
T(n) = 5T((4/3)^(k+1)) + 2
We can then use this substitution to solve the relation using, for example, the Master Theorem.
In conclusion, the substitution "n = (4/3)^k" is the best option because it simplifies the relation and makes it easier to solve.
