Un coche tarda 9hrs en recorrer un trayecto siendo su velocidad de 85km/h, ¿Cuánto tardará en recorrer el mismo trayecto a 70km/h?
The time taken to travel the distance 70 Km/h is 11 hours.
What is speed distance formula?Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took.
The formula can be rearranged in three ways:
speed = distance ÷ timedistance = speed × timetime = distance ÷ speedGiven:
time = 9 hours
speed = 85 Km/h
Now, distance
=speed * time
=85 * 9
= 765 km
As, the speed is 70 km/h
time = distance/ speed
time = 765 / 70
time = 10.92
time= 11 hours
Hence, the time taken to travel the distance 70 Km/h is 11 hours.

What are polynomial functions ?In mathematics, polynomial function can be defined as the equation which consist of coefficient, variables and exponents. All the equations such as quadratic equation, cubic equation which has non negative number as their powers are part of polynomial equation.
Some examples of polynomial equation are :
2x+53x = 93x² + 5x+19(x-3)³Now, for the given question,
let d = number of daisies
t = number of tulips
according to statement polynomial equation is,
d + t = 24 , say equation (i)
Twice as many daisies as tulips:
d=2t
Put the value of d in equation (i)
2t + t = 24
3t = 24
t = 8
As, number of daisies = 2 (number of tulips)
Therefore, d = 2t = 2 (8) = 16

f(x)=b x and g(x)=logbx are inverse functions. Explain why each of the following is true.
a. The translation f₁(x)=b x-h of f is equivalent to a vertical stretch or compression of f .
The function f₁(x) can be either vertical stretch or vertical compress: TRUE
What do we mean by Logarithmic Function?The following is the formula for basic logarithmic functions: Where b > 0, f(x) = logbx(r), y = logbx.It is the reciprocal of the exponential function x=b∧y.Log functions are denoted by natural logarithm (ln) and common logarithm (log).Here are a few examples of logarithmic functions:
f(x) = ln (x - 2)g(x) = log2(x + 5)-2h(x) = 2 log x, etc.So,
Given function:
f(x) = bˣg(x) = logbxThen,
f₁(x)=b^(x-h)f₁(x)=b^x/b^hNow, Put bˣ=f(x):
f₁(x)=f(x)/b^hf₁(x)=b^(-h)f(x)f₁(x)=c f(x)We discovered that:
c=b^(-h)So, depending on the values of b and h, c can be greater than or less than one.
Therefore, the statement "the function f₁(x) can be either vertical stretch or vertical compress" is TRUE.

A composite function exists as a function that depends on another function. A composite function exists formed when one function exists substituted into another function.
The value of f(g(x)) = (2x-6)/2 and g(f(x)) = x - 6.
What is meant by composition function?In mathematics, function composition exists as an operation ∘ that takes two functions f and g, and has a function h = g ∘ f such that h(x) = g. In this operation, the function g exists used to the result of applying the function f to x.
Function composition is a mathematical procedure where two functions, f, and g, are taken and a function, h = g ∘ f, is produced such that h(x) = g(f(x)). The function g exists used in this operation on the outcome of applying the function f to x.
Let the given functions be f(x) = x-3/2 and g(x) = 2x - 3
f(g(x)) = f(2x-3)
simplifying the above equation, we get
f(g(x)) = f(2x-3) = ((2x-3) - 3)/2
f(g(x)) = f(2x-3) = (2x-6)/2
f(g(x)) = (2x-6)/2
g(f(x)) = g(x-3/2)
simplifying the above equation, we get
g(f(x)) = g(x-3/2) = 2((x-3)/2) - 3
g(f(x)) = g(x-3/2) = x - 6
g(f(x)) = x - 6
Therefore, the value of f(g(x)) = (2x-6)/2 and g(f(x)) = x - 6.

If BD = 3, then it means that CD is also equal to 3 by definition of Isosceles triangle.
What is the missing length of the triangle?
We are given a triangle with the condition that BA ≅ CA. This means that side BA has a length equal to that of side CA.
Now, an Isosceles triangle is defined as a triangle that has at least two sides of equal length. This means that the given triangle ABC is an Isosceles triangle.
Now, since Triangle ABC is an Isosceles triangle, it means that when we draw a perpendicular line through the point joining the two equal sides, it bisects the third side of the triangle.
Thus, it means that BD is congruent to CD.
If BD = 3, then it means that CD is also equal to 3 by definition of Isosceles triangle.

(F) 5/4i (H) 5+5 i / 4 (G) 10-10i / 4-4i (I) 5-5i / 4
An equivalent form of 5 / ( 2 + 2 i ) is ( 5 -5 i ) / 4 [ option I ]
Given,
5 / ( 2 + 2 i )
To find its equivalent form we need to simplify the term by using the concept of conjugates.
Conjugate of a term results in opposite power of the imaginary part.
The conjugate of 2 + 2 i = 2 - 2 i
Multiply and divide the term with the conjugate
=> 5 * ( 2 - 2 i ) / ( 2 + 2 i ) * ( 2 - 2 i )
=> 10 - 10 i / 2 ² - ( 2 i ) ² [ ( a + b ) ( a - b ) = a ² - b ² ]
=> 10 - 10 i / 4 - (-4) [ i ² = - 1 ]
=> 10 - 10 i / 8
=> 5 - 5 i / 4
This matches with option I

you draw a red ball and you will win $12 is you draw a yellow ball. How much do you expect to
win or loss if you play this game 100 times?
After playing 100 times the player will loose $-16.67.
Given the outcomes and the probability is:
Outcome Probability
-$10 1 (cost to play)
$14 draw red 5/12
$12 draw yellow 4/12
therefore, expected probability = ∑x.p(x)
x is no of trials and
p(x) is probability of the results.
E(x) = (14)5/12 + (12)4/12 + (0)3/12 - 10
E(x) = -2/12
E(x) = -10.1667
For 100 games the expected value E(100x) =
E(100x) = E(x) × 100
E(100x) = -10.1667 × 100
E(100x) = -16.67 i.e loss after game.

The solution to the system where the system contains linear equations is (59/16, -65/32)
What are linear equations?Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to determine the solution to the system?A system of linear equations is a collection of at least two linear equations.
In this case, the system of equations is given as
2x + 12y = −17
3x + 2y = 7
Multiply through 3x + 2y = 7 by 6
So, we have
18x + 12y = 42
Subtract the equation 2x + 12y = −17 from 18x + 12y = 42
So, we have
18x - 2x + 12y - 12y = 42 + 17
Evaluate the like terms
So, we have
16x = 59
Divide both sides by 16
So, we have
x = 59/16
Substitute x = 59/16 in 3x + 2y = 7
3 x 59/16 + 2y = 7
This gives
177/16 + 2y = 7
So, we have
2y = 7 - 177/16
Evaluate the difference
2y = -65/16
Divide by 2
y = -65/32
Hence, the solution to the system where the system contains linear equations is (59/16, -65/32)

I am a 4-digit number larger than 2,500. No two of my digits are the same. The product of the thousands digit and the hundreds digit is equal to the ones digit. The sum of my digit is 16.
Read the clues. Find the number
Step-by-step explanation:
4-digit number abcd
a >= 2
a×b = d
so, 2 <= b <= 4 to allow a single digit result of a×b, and if b would be 1 or 0, the result would be either a copy of a or of b violating the rule that no 2 digits are the same.
that means a >= 3, because with a = 2 and b <= 4 the number can't be larger than 2500.
and that again means 2 <= b <= 3 and 3 <= a <= 4 to allow a single digit result of a×b.
the sum of "my digit" ? I guess you mean the sum of all digits is 16.
a + b + c + d = 16
so, my first guess :
a = 3
b = 2
therefore
d = 3×2 = 6
that means we have already 11 as sum of the digits, that leaves 5 for c.
so, the number would be
3256
the only alternative would start with a = 4 and then b = 2.
but that would make d = a×b = 8. abd 8 + 4 + 2 = 14, and that leaves for c only 2 to sum up to 16, and that would duplicate b.
so, 3256 is the only solution.

A customer should buy minimum 16 boxes of pavers.
In this question, a customer is ordering brick pavers to cover a rectangular walkway that is 3 feet by 15 feet and a square sitting area that is 6 feet on a side.
First we find the total area that will be covered by pavers.
Area of rectangle = length × width
Area of rectangle = 15 × 3
Area of rectangle = 45
And the area of square = side²
area of square = 6²
area of square = 36
So, the total area would be,
Total area = area of rectangle + area of square
Total area = 45 + 36
Total area = 81
So, the total area is 81 square feet.
one box of pavers covers 5.28 square feet.
So using unitary method,
81 / 5.28
= 15.534
≈ 16 boxes
This means, approximately 16 boxes will require to cover the above area.
Therefore, the customer should buy minimum 16 boxes of pavers.

Any real number that can be represented in the form of p/q, where q is not equal to 0 is called a rational number. The decimal expansion of rational numbers is terminating and repeating.
Calculation of the product of two rational numbers
Given two rational numbers,
8y - 4 / 10y - 5 and 5y -15 / 3y - 9
We need to multiply both the numbers i.e.
= (8y - 4 / 10y - 5) × (5y -15 / 3y - 9)
= (8y -4) × (5y - 15) / (10y - 5) × (3y - 9)
= (40y² - 140y + 20) / (30y² - 105y + 45)
= (8y² - 28y + 4) / (6y² - 21y + 9)
= (8y² - 28y + 4) / (6y² - 21y + 9)
The restriction is that the denominator, 6y² - 21y + 9 should not be 0.
