4/4​

The amount of sugar that went into each pitcher was 0.375, which was taken from the 3(3/4) cups of sugar utilized for the lemonade stand.

Division allows us to divide a large number of objects into equal-sized groups. Division is represented by the symbol ÷.

We can use the distributive property to divide larger numbers by breaking them down into smaller factors.

It is implied that Lucy made her lemonade stand using 3 3/4 cups of sugar.

Further, she distributed the sugar into 6 pitchers in equal portions.

Therefore, we need to divide the total cups of sugar by 6 to get the value of sugar that went into each pitcher.

sugar went into each pitcher = 3(3/4) ÷ 6

                                                 = (9/4) ÷ 6

                                                 = 2.25 ÷ 6

                                                 = 0.375

Therefore, each pitcher of sugar contained 0.375 of the 3(3/4) cups of sugar utilized for the lemonade stand.

The values of the composite function are (f o g)(x) = √2x² - 8 and (f o g)(x) = 2x - 8, while their domains are x > 2 and 0 < x < oo, respectively

Lastly, the value of (g o f)(3) is -2

Composite function 1

The functions are given as

f(x) = √x

g(x) = 2x² - 8

The composite function definition is given as

(f o g)(x)

This composite function is calculated using the following composite function formula

(f o g)(x) = f(g(x))

Substitute the known values in the above equation

(f o g)(x) = √g(x)

This gives

(f o g)(x) = √2x² - 8

For the domain, we have

2x² - 8 > 0

This gives

x > 2

Composite function 2

The functions are given as

f(x) = √x

g(x) = 2x² - 8

The composite function definition is given as

(g o f)(x)

This composite function is calculated using the following composite function formula

(g o f)(x) = g(f(x))

Substitute the known values in the above equation

(g o f)(x) = 2f(x)² - 8

This gives

(g o f)(x) = 2(√x)² - 8

Evaluate

(g o f)(x) = 2x - 8

The function is a linear function

So the domain is the set of all real values

Substitute 3 for x in (g o f)(x) = 2x - 8

(g o f)(3) = 2(3) - 8

Evaluate

(g o f)(3) = -2

The time (in hours) taken by the bus and the car to travel between the two towns in terms of x is 5 hours 20 minutes and 4 hours respectively and the equation in x formed is [tex]x^2 + 15x -2700=0[/tex]

Given that:-

Distance between towns A and B = 240 km

A bus takes 80 minutes longer than a car to travel between the two towns.

The car is travelling at 15 km/h faster than the bus which is travelling at x km/h.

Let the speed of the bus be s km/hr and,

The time taken by the car to travel from A to B be t hours.

Hence,

(15+x)*t = (t + 80/60)*x

15t + xt = xt + 4x/3

15t = 4x/3

t = 4x/45 hours.

Hence,

(15 + x)*(4x/45) = 240

x(x + 15)/45 = 60

[tex](x^2 + 15x) = 60*45[/tex]

[tex](x^2 + 15x) = 2700\\x^2 + 15x -2700=0\\x^2-45x+60x-2700 = 0[/tex]

x(x-45) +60(x - 45) = 0

(x - 45)(x + 60) = 0

x = 45,-60

As the time cannot be negative,

x = 45 km/hr

t = (4*45)/45

t = 4 hours (time taken by car)

Time taken by bus = 4 hours + 80 minutes = 5 hours 20 minutes

The correct equation that is balanced using the given numbers once is;

5(-1 + (-3)) = (7 * -4) + 8

There are some properties of Algebra such as;

Commutative Property of Addition or multiplication

Associative Property of Addition or multiplication

Transitive Property

Distributive Property

Now, looking at the given numbers, one good idea is to use only a positive digit outside the bracket on the left hand side of the equation to make it easy to balance on the right hand side of the equation. Thus, for the left hand side we will try;

5(-1 + (-3))

When that is solved we will get -20

Now, to balance that on the right hand side , we will have;

The value of n in the right triangle is 12 cm.

The shortest side of a right angle triangle is 6cm shorter than the hypotenuse.

The difference in length of the other two sides is 3cm.

The hypotenuse side is the longest side of a right triangle.

Hence,

hypotenuse side = n - 3 + 6

hypotenuse side = n + 3

Shortest side of the right triangle = n - 3

Other side = n

Therefore, using Pythagoras theorem,

(n + 3)² = (n - 3)² + n²

(n + 3)(n + 3) = (n - 3)(n - 3) + n²

n² + 3n + 3n + 9 = n² -3n -3n + 9 + n²

n² + 6n + 9 = 2n² - 6n + 9

Therefore,

2n² - n² + 9 - 9  = 6n + 6n

n² = 12n

n² - 12n = 0

n(n - 12) = 0

n = 0 and n = 12

The area of mathematics known as algebra is used to help express issues or circumstances into mathematical expressions. We employ integers with definite or fixed values in algebra, such as 2, 7, 0.068, etc. In addition to integers, algebra uses variables like x, y, and z.

The solution is written as below:

Given: d= f

2d + 4e - 3f = 1 --------------1

and - 3d + 2e + 4f = 5----------------------2

Put the value of f as d because it is given,

thus equation becomes; 2d+ 4e - 3d= 1 ⇒ 4e- d= 1 ----3

-3d+2e +4d= 5 ⇒  2e+ d=5 ----4

Thus on solving 3 and 4 we get;

[tex]4e-d=1\\+2e+d=5\\[/tex]

We get 6e= 6 which implies e= 1

And putting this value of e in equation 3 we get,

Guess it's 7.040 yards in 4 miles

Step-by-step explanation:

8.800÷5= 1.760 in 1 yard

4×1.760=7.040

prove me wrong

Answer:

In both number lines, from 0-8,800 and 0-5 there are 5 notches from the first and last, so what you first want to do is solve for the first number line. You can do this by divideing the largest number by the number of notchest on the line:

8,800/5 = 1760

So the notch after 0 will be 1760. To finish the pattern, you want to add the number you got after dividing the total, by itself, 4 more times, as shown:

1,760 + 1,760 = 3,520

3,520 + 1,760 = 5,280

5,280 + 1,760 = 7,040

7,040 + 1,760 = 8,800

Now the number line will look like this:

0, 1760, 3520, 5280, 7040, 8800

0, 1, 2, 3, 4, 5

Compared to the second number line we find that there are 7,040 yards in 4 miles!

To get the slope, let us use points A and B;

A(0, 0) and B(1, 0.9)

Thus;

Slope = (0.9 - 0)/(1 - 0)

Slope = 0.9
