If a van traveled 240 miles in 4 hours, how far could the van travel in 5 hours?
Answers
Answer: i think 300
Step-by-step explanation: i divided 240 by 4 and got 60 then multiplied 60X5=300
Answer:
300 miles in five hours.
Step-by-step explanation:
speed = distance/time
distance = speed*time
240/4=60
d= 60*5
d=300 miles in five hours.
Word explanation:
You can use the formula, speed=distance/time to find the speed which is 60 mph. Now use the formula for distance which is distance= speed*time. The answer would be 300 miles in five hours.

Answer:
The original price of the toaster is 2000
Step-by-step explanation:
Given: Toaster price = 2240
VAT = 12%
VAT amount = ?(I'll include this one)
Assume the original price be x.
Let the original price be x
Then, x + 12% of x = 2240
x+12/100x x = 2240
100x+12x/ 100= 2240
112x/100=2240
112x = 2240 x 100 ⇒ 224000
x = 224000/112
x = 2000.
So, the original price of toaster = Rs. 2000.
The VAT amount = 2240 - 2000 ⇒ Rs. 240.
The VAT amount is Rs. 240.

Explanation:
We can use the discriminant formula to determine how many (and what type of) roots we have. The term "root" is another word for "solution" or "x intercept". It's the x value that makes y = 0.
Any quadratic is of the form ax^2 + bx + c = 0
The discriminant formula is
d = b^2 - 4ac
which is found underneath the square root in the quadratic formula.
Here are the three possible outcomes
d > 0: we get two different real number solutionsd = 0: we have exactly one real number solutiond < 0: there are no real number solutions (the two solutions are complex or imaginary numbers).With all that in mind, let's find the discriminant of the first equation on the very left.
First we need to get it into standard form ax^2+bx+c = 0
5x^2 + 2 = 4x
5x^2 - 4x + 2 = 0
We see that
a = 5b = -4c = 2Computing the discriminant gets us...
d = b^2 - 4ac
d = (-4)^2 - 4(5)(2)
d = 16 - 40
d = -24
The actual discriminant value itself doesn't matter. All we care about is whether its positive, zero, or negative.
In this case, we get a negative discriminant. So this equation goes to the "no real solutions" column.
-------------------------
Let's move onto the next quadratic
3x^2 + 24x = -48
3x^2 + 24x + 48 = 0
a = 3, b = 24, c = 48
d = b^2 - 4ac
d = 24^2 - 4(3)(48)
d = 0
The discriminant of zero means this equation goes into the "exactly one real solution" category.
-------------------------
For the next equation, we don't need to use the discriminant formula here.
Notice that the right hand side is negative, but the left side is never negative because 3 is positive and (x+5)^2 is never negative. There is no way to have 3(x+5)^2 be negative if we let x be a real number only.
The equation 3(x+5)^2 = -2 goes into "no real solutions" pile.
-------------------------
For the last equation, we have
a = 4, b = -16, c = 0
So,
d = b^2 - 4ac
d = (-16)^2 - 4(4)(0)
d = 256
The result is a positive number, so we have two different solutions.
The discriminant is a perfect square which means we not only have real number solutions, but those solutions are rational numbers. This only works when a,b,c are rational as well.

an artist is constructing a piece of art in the shape of rectangle. The artist wants to use string to tightly tie each vertex of rectangle to the other three vertices. The rectangle is 12.0 feet wide and 7.0 feet long. how much string should the artist use? round your answer to the nearest tenth of a foot
feet of string:
Answers
Answer:
An artist use 51.9 feet of string for constructing a piece of art in the shape of rectangle
Step-by-step explanation:
Here an artist is constructing a piece of art in the shape of rectangle having length 12 feet & width of 7 feet
Since the artist wants to use string to tightly tie each vertex of rectangle to the other three vertices. Hence one string will tie in a diagonal way
Hence total length of string will be
Total length = Perimeter of rectangle + length of diagonal
Perimeter of rectangle = 2( length + width ) = 2 ( 12 + 7 ) = 2 x 19 = 38 feet
Length of diagonal given by Pythagoras theorem
[tex]\mathrm{Length = { \left( { a }^{ 2 } + { b }^{ 2 } \right) }^{ 0.5 } = { \left( { 12 }^{ 2 } + { 7 }^{ 2 } \right) }^{ 0.5 } = 13.89244\:\:feet}[/tex]
Hence
Total length = Perimeter of rectangle + length of diagonal
Total length = 38 feet + 13.89244 feet = 51.9 feet
Hence an artist use 51.9 feet of string for constructing a piece of art in the shape of rectangle

Trying to factor by splitting the middle term
2.1 Factoring 2t2-15t+22
The first term is, 2t2 its coefficient is 2 .
The middle term is, -15t its coefficient is -15 .
The last term, "the constant", is +22
Step-1 : Multiply the coefficient of the first term by the constant 2 • 22 = 44
Step-2 : Find two factors of 44 whose sum equals the coefficient of the middle term, which is -15 .
-44 + -1 = -45
-22 + -2 = -24
-11 + -4 = -15 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -11 and -4
2t2 - 11t - 4t - 22
Step-4 : Add up the first 2 terms, pulling out like factors :

Add up the last 2 terms, pulling out common factors :

Step-5 : Add up the four terms of step 4 :

Theory - Roots of a product
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
3.2 Solve : 2t-11 = 0
Add 11 to both sides of the equation :
2t = 11
Divide both sides of the equation by 2:
t = 11/2 = 5.500
Solving a Single Variable Equation:
3.3 Solve : t-2 = 0
Add 2 to both sides of the equation :
t = 2
Supplement : Solving Quadratic Equation Directly
Solving 2t2-15t+22 = 0 directly
Earlier we factored this polynomial by splitting the middle term. let us now solve the equation by Completing The Square and by using the Quadratic Formula
Parabola, Finding the Vertex:
4.1 Find the Vertex of y = 2t2-15t+22
Parabolas have a highest or a lowest point called the Vertex . Our parabola opens up and accordingly has a lowest point (AKA absolute minimum) . We know this even before plotting "y" because the coefficient of the first term, 2 , is positive (greater than zero).
Each parabola has a vertical line of symmetry that passes through its vertex. Because of this symmetry, the line of symmetry would, for example, pass through the midpoint of the two x -intercepts (roots or solutions) of the parabola. That is, if the parabola has indeed two real solutions.
Parabolas can model many real life situations, such as the height above ground, of an object thrown upward, after some period of time. The vertex of the parabola can provide us with information, such as the maximum height that object, thrown upwards, can reach. For this reason we want to be able to find the coordinates of the vertex.
For any parabola,At2+Bt+C,the t -coordinate of the vertex is given by -B/(2A) . In our case the t coordinate is 3.7500
Plugging into the parabola formula 3.7500 for t we can calculate the y -coordinate :
y = 2.0 * 3.75 * 3.75 - 15.0 * 3.75 + 22.0
or y = -6.125-0

The rule is the number of line which is n. (n-2)*(n-1) divided by 2
The slope of that line through the origin that divides the region bounded is 1.0315
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
given that,
y = 5x - 3x2
5x - 3x2 = 0
x(5 - 3x) = 0
x = 0 , x = 5/3
Area under y = 5x - 3x2 is A = [0 to 5/3] 5x - 3x2 dx
A = [0 to 5/3] 5x2/2 - 3x3/3
A = [0 to 5/3] 5x2/2 - x3
A = 5(5/3)2/2 - (5/3)3 = 125/54
line passing through origin is in the form of y = mx
==> mx = 5x - 3x2
==> 3x2 + mx - 5x = 0
==> 3x2 + x(m -5) = 0
=> x(3x + (m -5)) = 0
==> x = 0 , x = (5 -m)/3
Area under y = 5x - 3x2 and y = mx is (125/54)/2 = 125/108
==> ?[0 to (5 -m)/3] 5x - 3x2 -mx dx = 125/108
==> ?[0 to (5 -m)/3] (5 - m)x - 3x2 dx = 125/108
==> [0 to (5 -m)/3] (5 - m)x2/2 - x3 = 125/108
==> (5 - m)[(5 -m)/3]2/2 - ((5 -m)/3)3 = 125/108
==> (5 -m)3/18 - (5 -m)3/27 = 125/108
==> (5 -m)3/54 = 125/108
==> (5 -m)3 = 125/2
==> (5 -m) = 3.9685
==> m = 5 - 3.9685
==> m = 1.0315
Hence slope of line = 1.0315
