The proportion of the drink that is juice is one part juice to four parts water. The proportion of the drink that is juice is 1:5. This can be written in fraction as 1/5 , in decimal as 0.25 and in percentage as 25%.

A ratio is a mathematical comparison of two or more values. It is typically written as a fraction, with the values being separated by a colon (e.g. 3:4). The values in a ratio can represent any type of quantity, such as length, weight, or time.

A proportion is a statement that two ratios are equal. For example, if the ratio of boys to girls in a class is 4:5, and the ratio of boys to the total number of students is 12:20, then the two ratios are in proportion. In contrast, a ratio is simply a comparison of two or more values without any equality statement.

An orange drink is made using one part juice to four parts water. The proportion of the drink that is juice is 1/5.The proportion of the drink that is juice is 1/5, which can be expressed as a decimal as 0.2 (1/5 = 0.2) or as a percentage as 20% (0.2 x 100 = 20).

The area of given figure will be sum of of triangles and rectangles included in it and area will be = 27.7 m^2.

What is a triangle?

In Geometry, triangles are the type of polygons, which have three sides and three vertices. This is a two-dimensional figure with three straight sides. A triangle is considered a 3-sided polygon. The sum of all the three angles of a triangle is equal to 180°. The triangle is contained in a single plane. Based on its sides and angle measurement, the triangle has six types.

Based on the sides of a triangle, a triangle is classified into 3 types, namely:

Scalene Triangle – All the sides are of different measures.

Isosceles Triangle – Two sides of a triangle are of the same measure and the remaining side has a different measure.

Equilateral Triangle – All the 3 sides of a triangle are of the same measure.

Based on the angles of a triangle, a triangle is classified into 3 types, namely:

Acute Angle Triangle – All the angles of a triangle is less than 90°.

Obtuse Angle Triangle – One of the angles of a triangle is greater than 90°.

Right Angle Triangle – One of the angles of a triangle is equal to 90°.

Now,

As area of rectangle=length*breadth

and area of triangle = 1/2*base*height

Therefore area of figure=1/2*1*5+2*5+1/2*2*2+1/2*2*3+1*3+1/2*1*2+3*2

=5/2+10+2+3+3+1+6

Answer:

62.5%

Step-by-step explanation:

We know that Mike's whole drink is 16 ounces.

If he drinks 6 ounces, that means we are subtracting 6 from the total (16 ounces)

16 - 6 = 10

Now that we have 10 ounces left, we have to find out what percent that is out of the total (16 ounces)

To do this, we must create a fraction: 10/16

You can simplify this by dividing both sides by 2, getting us 5/8

Now, you can either use long division, or a calculator or know that 1/8 is .125, then multiply that by 5 to get .625

Now, the question is asking us for a percent, not a decimal, so we must convert .625 to a percent by multipling everything by 100. This just means moving every number to the right 2 (keep the decimal still)

Once done, you will get 62.5% left!

We can begin by isolating the absolute value on one side of the inequality:

|1/4x+3|<3/2

We can then split this inequality into two cases, one for when 1/4x+3 is positive and one for when it is negative:

1/4x+3>0: 1/4x+3>3/2, so multiplying both sides by 4, we get x>-13 and x<-11

1/4x+3<0: 1/4x+3<-3/2, so multiplying both sides by -4, we get x<-24 and x>0

An exponential function is a function of the form f(x) = a^x, where a is a positive constant (a > 0). An exponential equation is an equation that involves an exponential function.

What exactly makes a function exponential?

A mathematical function with the formula f (x) = an x is an exponential function. where an is a constant known as the function's base and x is a variable. The transcendental number e, or roughly 2.71828, is the exponential-function base that is most frequently encountered.

For example, the function f(x) = 2^x is an exponential function, because it is of the form f(x) = a^x, where a = 2. The equation y = 2^x is an exponential equation, because it involves the exponential function f(x) = 2^x.

To determine whether an equation is an exponential equation, you can look for the presence of an exponential function. If the equation is of the form f(x) = a^x, where a is a positive constant, then it is an exponential equation.

If the equation is not in this form, but it involves an exponential function, it is still an exponential equation. For example, the equation y = 2^x + 1 is an exponential equation, because it involves the exponential function f(x) = 2^x.

Note that an exponential equation does not have to involve an exponent that is a positive integer. For example, the equation y = (1/2)^x is also an exponential equation, because it involves the exponential function f(x) = (1/2)^x.

For a linear function, we know that

if y = a+bx , then E(y)= a+b× E(x), E denotes the mean.

E(w) = E (7+2x)

       = 7+2 × E(x)

So mean of w will be 31.

As for standard deviation, σ =√Var

  Var (w) = Var( 2x+7)

               = Var(2x) + Var(7)

As variance of a constant term =0

    Var(w) = Var(2x)

As per the equation for variance Var(ax) = a²× Var(x)

So Var(w) = 2²× Var(x)   ( Standard deviation of x= √Var(x)

We have the length of CE as 18.4 cm.

Since the rectangles ABCD and DEFG are congruent, all sides of rectangle ABCD will be equal to the corresponding sides of rectangle DEFG. Since AB = 7 cm and AD = 17 cm in rectangle ABCD, we can conclude that DE = 7 cm and DF = 17 cm in rectangle DEFG.

Since CE is a diagonal of rectangle DEFG, it can be found using the Pythagorean theorem. In a rectangle, the diagonal is the hypotenuse of a right triangle formed by one side and one side's corresponding side.

Therefore, CE = √(DE² + DF²) = √(7² + 17²) = √(49 + 289) = √(338) = 18.4 cm

The area of quadrilateral BEFD, by using Heron’s Formula, is 16.

To calculate the area of quadrilateral BEFD, we first need to calculate the area of the entire triangle ΔABC. This can be done by using Heron’s Formula, which states that the area of a triangle is equal to the square root of the semi-perimeter multiplied by the product of the sides of the triangle, minus the sum of the squares of the sides.

In this case, the semi-perimeter is (a + b + c)/2, where a, b, and c are the sides of the triangle. The sides of triangle ΔABC are 9, 10 and 11, respectively. Applying Heron’s Formula, we have:

Area of ΔABC = √(9 + 10 + 11)/2 * (9 * 10 * 11) - (9^2 + 10^2 + 11^2)

= √27 * 990 – 1230

= √990

= 31.6

Now, since we know the areas of the three triangles within ΔABC (4, 9, and 7), we can subtract the sum of those three from the total area of ΔABC to calculate the area of quadrilateral BEFD.

Area of BEFD = 31.6 – (4 + 9 + 7)

= 31.6 – 20

= 11.6

A function that can change into another function in the opposite direction is known as an inverse function or anti function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. If a function is written as "f" or "F," the inverse function is written as "f-1" or "F-1."

The original value for which a function produced its output is returned by the inverse function. Consider the inverse relationship between the functions f and g: f(g(x)) = g(f(x)) = x. The initial value is fetched by a function that is its inverse. Therefore, the inverse of f is g(y) = (y-5)/2 = x. (x).
