Step-by-step explanation:
We can use basic exponent rules to simplify this expression.
We know that [tex]a^b \div a^c = a^{b-c}[/tex].
Since we have the same base (7) and different exponents (x, y), we can subtract the exponents and raise the base to that power.

Of the students in the marching band, 55%
plan to go to the school dance. If there are
110 students in the marching band that are
going to the dance, how many students
are in the marching band?
Answers
The answer is 200 because when you divide 110 from 55% you get 200.
Of the students in the marching band, 55% plan to go to the school dance, so there are 200 students in the marching band.
What is Percentage?A certain portion or amount in every hundred is referred to as a percentage. The fraction is denoted by the sign "%," and its denominator is 100.
The Latin word "per centum," which means "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentages are fractions. To put it another way, it's the relationship between a component and a whole in which the value of the whole is always assumed to be 100.
From the given values in the question,
Assume that total number of students in marching band is x.
55% of x = 110 or,
(55/100) × x = 110
x = (110 × 100) / 55
x = 200.
Hence, it concludes that there are total 200 students are in the marching band.

Given emelia earns $8.74 per hour plus a gas allowance of $3.50 per day at her job
We need to find how much does emelia's job pay in a day when she works 5 and a half hours
Let us write the given data in the form of expression.
8.74x+3.50
Now for 5 and half hours we have to calculate
8.74(5.5)+3.50

A figure called an angle is one in which two rays originate from the same point. In this area, you could also encounter contrasting and related viewpoints.
Given that the two angles are 85 and 145. The internal angles will be calculated as,
180 - 85 = 95

Answers
Answer:
x = 14Step-by-step explanation:
7x + 9 + 5x + 3 = 180
7x + 5x = 180 - 3 - 9
12x = 168
x = 168 / 12
x = 14
Answer:
14
Step-by-step explanation:
By applying the vertical angle theorem to 5x + 3, using same-side exterior angle theorem, we can find that:
(7x + 9) + (5x + 3) = 180
Now to find x, we can just solve for x in the equation we found.
(7x + 9) + (5x + 3) = 180
Combine like terms.
12x + 12 = 180
Subtract 12 from both sides.
12x = 168
Divide both sides by 12.
x = 14
So the value of x would be 14.

the sum of a rational number and a irrational number
Answers
Answer: The sum of rational and irrational number is always irrational...
Answer:
When both rational and irrational numbers are written in decimal form, rational numbers can be written as finite decimals and infinite recurring decimals, such as 4=4.0, 4/5=0.8, 1/3=0.33333... and irrational numbers can only be written as infinite non-recurring decimals, such as √ 2=1.414213562…………According to this point, people define irrational numbers as infinite non-recurring decimals. 2. All rational numbers can be written as the ratio of two integers; irrational numbers cannot.
(Rational number): A number that can be accurately expressed as the ratio of two integers. Such as 3, -98.11, 5.72727272..., 7/22 are all rational numbers. Integers and fractions are all rational numbers. Rational numbers can also be divided into positive rational numbers, 0 and negative rational numbers. Irrational numbers refer to infinite and non-recurring decimals such as: π ·The difference between irrational and rational numbers: 1. When both rational and irrational numbers are written in decimal form, rational numbers can be written as finite decimals and infinite cyclic decimals. For example, 4=4.0, 4/5=0.8, 1/3=0.33333... and irrational numbers can only be written as infinite and non-cyclic decimals. For example, √2=1.414213562…………According to this point, people define irrational numbers as infinite and non-cyclic decimals. 2, all rational numbers can be written as the ratio of two integers; irrational numbers cannot. Based on this, some people suggested that irrational numbers should be removed from the "irrational" hat, and rational numbers should be called "comparative numbers" and irrational numbers should be called "irrational numbers". Originally, irrational numbers are not unreasonable, but people don't know much about it at first. Using the main difference between rational and irrational numbers, we can prove that √2 is irrational. Proof: Assume that √2 is not an irrational number, but a rational number.Since √2 is a rational number, it must be written as the ratio of two integers: √2 = p / q Since p and q do not have a common factor to be reduced, p / q can be considered to be the reduced fraction, the simplest form of fraction. Put √2 = p / q squared on both sides Get 2 = (p ^ 2)/(q ^ 2) Is 2 (q ^ 2) = p ^ 2 Since 2q ^ 2 is an even number, p must be an even number, so set p = 2m From 2 (q ^ 2) = 4 (m ^ 2) Get q ^ 2 = 2m ^ 2 Similarly, q must be an even number, let q = 2n Since p and q are both even numbers, they must have a common factor of 2, which contradicts the previous assumption that p/q is a reduced fraction. This contradiction is caused by the assumption that √2 is a rational number. Therefore √2 is an irrational number.
