Solving for the variable gives f = 100 - 2h/5

Subject of formula can be defined as the variable that is expressed in terms of other variables in a given expression, function of equation.

It is the variable worked out in an equation and left to stand on its own on one side of the equality sign

Given the equation;

5f+2h = 100

To make 'f' the subject of formula, we take the following steps;

Take '2' over the equality sign

5f = 100 - 2h

Now, let's make 'f' the subject by dividing both sides by its coefficient which is 5

We have;

5f/5 = 100 - 2h/5

Divide through

f = 100 - 2h/5

Thus, solving for the variable gives f = 100 - 2h/5

$72 is 4.5% of 6.25 amount. 6.25 Percentage of  72 is 4.5.

By considering the given information

[tex]72\times x=4.5\\x=\frac{4.5}{72}\times 100\\ x=6.25[/tex]

A number or ratio that can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage therefore refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it. percent, which is a relative value used to denote hundredths of any quantity. Since one percent (symbolized as 1%) is equal to one hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.

By using Heron's formula and standard formula for the area of a triangle, the area of the composite figure is 921006.497 square meters.

In this problem we must determine the area of a composite figure, which consists in subtracting the area of an isosceles triangle from the area of the equilateral triangle:

Big triangle

The area of the big triangle is determined by Heron's formula:

s = [3 · (520 m)] / 2

s = 780 m

A = √[(780 m) · (1560 m - 520 m)³]

A ≈936693.077 m²

Small triangle

H = (520 m) · sin 60°

H ≈ 450.333 m

h = 450.333 m - 390 m

h = 60.333 m

A = 0.5 · (520 m) · (60.333 m)

A = 15686.580 m²

Then, the area of the composite figure is 921006.497 square meters.

The length of the base will be equal to 65.99 centimeters.

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

The formula for the Pythagorean theorem is given below:-

H² = B² + P²

Given that in a right triangle if the hypotenuse is 70 cm and the shorter leg is one-third the length of the longer leg.

P = 70/ 3 cm

H = 70 cm

The value of the leg will be calculated as:-

H² = B² + P²

70² = B² + (70/3)²

B² = 70² -  (70/3)²

B = √4355

B = 65.99 cm

Therefore, the length of the base will be equal to 65.99 centimeters.

  angle 5

Step-by-step explanation:

Given transversal x crossing lines y and z and angles numbered 1 to 8, you want the number of the angle that is an alternate interior angle to angle 4.

In this context, "alternate" mean the angles are on opposite sides of the transversal. "Interior" means the angles are between the lines the transversal crosses.

The term "alternate interior angles" is used to refer to angles that have their vertices at the intersection points where the two lines cross the transversal. (It excludes angles that have the same vertex, or do not share a side.)

The angle that is an alternate interior angle relative to angle 4 is angle 5.

The length with scale factor to form quadrilateral 1/2, A'B' is √5 units when AB is √20.

The formula to find the distance between the two points is usually given by

d=√((x2 – x1)² + (y2 – y1)²).

Given :

Quadrilateral ABCD is dilated at the center (0,0) with a scale factor of 1/2 to form quadrilateral A'B'C'D'.

Points - A(0,4), B(4,2), C(4,-4), and D(-2,-2).

So, the points of the quadrilateral ABCD becomes:

So,  length of A'B'

AB = √(4-0) ² +(2 -4)²

AB = √16 + 4

AB = √20

AB = 2√5

A'B' = 1/2 AB
