Answer:

160

Step-by-step explanation:

Find the area of the base

10 × 8 = 80

Multiply the height

80 × 6 = 480

then the the pyramid prism takes 1/3 so...

we then multiply 480 by 1/3

480 × 1/3 = 160

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.

Answer:

50

Step-by-step explanation:

The measure of the angle ∠A will be 50°. The correct option is A.

Straight lines with little depth or width are present. You will learn about a number of lines, including transversal, intersecting, and perpendicular lines. 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

180 - 145 = 35

The angle A will be calculated as below,
∠A = 180 - 35 - 95

∠A = 50°

If there is a variable term and a constant on each side of the equation, then you will need to use the addition or subtraction property of equality once to isolate the variable term and once to isolate the constant.

Answer:

X-3

Step-by-step explanation:

The graph shifted 3 units to the left so you subtract from the x value.

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.

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.

Answer:

Step-by-step explanation:

parallel angles are equal

3x + 21 = 6x - 60

combine similar terms:

3x - 6x = -60 - 21

-3x = -81

x = 81/3

x = 27

now, plugin the value of x=27 back into the equation to get the angle:

= 3x + 21

= 3(27) + 21

= 102

= 6x - 60

= 6(27) - 60

= 102

as you noticed, both values are equal 102 = 102 because its a parallel angles

so the equation is 3x + 21 = 6x - 60
