Answer:

Step-by-step explanation:

Angle (x+1) is equal to 92 degrees, and x equals 91. If x equals 91, then (x+1) equals 92. (x+1) and angle y are equal angles, so therefore, you can determine that angle y is equal to 92 degrees.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

8% = 50 people

Multiply 100/8 on both sides,

100% = 100/8 x 50 people

100% = 625 people

Thus,

There are 625 readers.

In a two-digit number, the tens digit is 5 less than the units digit. The number itself is five more than three times the sum of its digits. What is the number?

Answers

38. Mark Brainliest Please

The tens digit is 3 and the unit digit is 8. So, the number is 38.

Important information:

The tens digit is 5 less than the unit digit.The number itself is five more than three times the sum of its digits. System of equations:

Let x be the tens digit and y be the unit digit.

The tens digit is 5 less than the unit digit.

[tex]x=y-5[/tex] ...(i)

The number itself is five more than three times the sum of its digits.

[tex]10x+y=3(x+y)+5[/tex]

[tex]10x+y-3x-3y=5[/tex]

[tex]7x-2y=5[/tex] ...(ii)

Using (i) and (ii), we get

[tex]7(y-5)-2y=5[/tex]

[tex]7y-35-2y=5[/tex]

[tex]5y=40[/tex]

[tex]y=8[/tex]

Substitute this value in (i).

[tex]x=8-5[/tex]

[tex]x=3[/tex]

Therefore, the number is 38.

Make x the subject of formula x²/a²+y²/b²=1

Answers

Answer:

x = ± [tex]\sqrt{\frac{a^2b^2-a^2y^2}{b^2} }[/tex]

Step-by-step explanation:

Given

[tex]\frac{x^2}{a^2}[/tex] + [tex]\frac{y^2}{b^2}[/tex] = 1

Multiply through by a²b² to clear the fractions

b²x² + a²y² = a²b² ( subtract a²y² from both sides )

b²x² = a²b² - a²y² ( divide both sides by b² )

x² = [tex]\frac{a^2b^2-a^2y^2}{b^2}[/tex] ( take the square root of both sides )

x = ± [tex]\sqrt{\frac{a^2b^2-a^2y^2}{b^2} }[/tex]

In formula x²/a²+y²/b²=1

Value of x as subject, x = ± [a√(b² - y²)]/b

What is equation?

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side.

Given equation,

x²/a² + y²/b² = 1

moving y²/b² to right side

x²/a² = 1 - y²/b²

multiplying a² on both sides

a². x²/a² = a². 1 - a². y²/b²

Simplifying

x² = a² - a²y²/b²

x = ± √(a² - a²y²/b²)

x = ± a√(1 - y²/b²)

x = ± [a√(b² - y²)]/b

Hence, value of x = ±[a√(b² - y²)]/b in formula x²/a² + y²/b² = 1
