Step-by-step explanation:

1 LY = 9.46 * 10¹²
S = 6.8 * 10¹³

S = 6.8 * 10¹³/9.46 * 10¹² ≈ 7.188 LY

Answer:

B)2

Step-by-step explanation:

We want to figure out the 415th digit of this repeating decimal.

[tex] \dfrac{2}{7} = 0. \overline{285714}[/tex]

Obviously it's almost impossible and absurd to find the answer by writing down all the 415 digits. So instead we're going to use some tricks to do so.

There're 6 repeating digits. dividing 415 by 6 yields 69.17. Now multiplying 69 by 6 yields 414 which means that the 414th digit of the repeating decimal would be the last digit of the repeating digits, that is,4 and hence The 415th digit of the repeating decimal is gonna be 2. Hence the answer is B

Step-by-step explanation:

21.147 may have the most numbers, but it is the smallest because there is a 1 in the tenths place

Answer:

23

Step-by-step explanation:

To find the Greatest Common Factor, or GCF, we need to factor the first 2 numbers and then find the greatest number that is both present in the prime factorization of both numbers.

253 = 1 * 11 * 23

345 = 3 * 5 * 23

Since 23 is both present in both numbers and is the greatest, the GCF of 253 and 345 is 23.

Answer:  No

Explanation:

Replace p with 2 and simplify

8 ≠ 3p + 2

8 ≠ 3(2) + 2

8 ≠ 6 + 2

8 ≠ 8

We get a false claim, so the original inequality 8 ≠ 3p + 2 is false when p = 2. Meaning that p = 2 is not a solution.

If the "not equal" sign was changed to an equal sign, then we would have a solution.

Answer:

no / false

Step-by-step explanation:

If we set the "p" in this equation to be equal to 2 (p = 2), we can test this inequality:

8 ≠ 3p + 2

8 ≠ 3(2) + 2

8 ≠ 6 + 2

8 ≠ 8

FALSE STATEMENT

so, p = 2 is not a solution to this inequality

(no)

Answer: A

Step-by-step explanation:

Let's fact check all the answer choices:

A. He used the commutative property

Well, the commutative property states that you can put the equation in any order and the result doesn't change. In step1, andrew makes the equation  -5.7+2.2 into 2.2-5.7. Both of these equations equal -3.5, so yes, he used the commutative property.

B.He used the distributive  property.

We know this is wrong because the distributive property involves multiplication. An Example of an equation that involves the distributive  property is 3(2+1), or 3x(2+1).

C. He used the associative property.

This is wrong because the associative  property involves grouping the equation into different parentheses , which doesn't happen.

D.  The answer is incorrect

Using a calculator , we know this is wrong.

A. |–4.8| > |2.5|

Step-by-step explanation:

When, you compare the distance between stuff, you always compare the absolute value of each thing. And even this equation does not ask for the distance between stuff, it still does require you to compare it with absolute value. The negative sign is only their because they are digging up the ground and not adding to the ground. However, when comparing it, we want to find what is deeper, so we use absolute value making it both positive to compare it fairly. However, if it asked which one was less deep you will use the negative signs. But based on this situation, you don't need to.

Step-by-step explanation:

you are adding exponent with the same denominator if its easier for you in this example you can set the denominator equal to 10.

Sum= adding

2/5 +4/5 =6/5 or 1 1/5

if you want to do it with the denominator equal to 10 just multiply each side by 2.

(2/5 +4/5)x 2

4/10 + 8/10 = 12/10

Answer:

3/5 of the students in the class are not in accounting majors

Step-by-step explanation:

The total number of males in the class is 3/8

3/5 of them are accounting majors

The ones who are not in accounting majors are;

3/8 - 3/5 = 9/40

The total number of female students in the class is;

8/8 - 3/8 = 5/8

1/4 of them are accounting majors

The ones who are not in accounting majors are;

5/8 - 1/4 = 3/8

Total number of students not in accounting majors;

9/40 + 3/8

= 24/40

= 3/5

The area of the quadrilateral is 39.84 sq.units.

A quadrilateral is a polygon with four sides.

The quadrilateral ABCD is divided into 2 triangles by its diagonal

The area of Quadrilateral will be equal to the sum of the area of tho scalene triangles

The area of a scalene triangle is given by

[tex]\rm A = \sqrt{s (s-a)(s-b)(s-c)[/tex]

s is the semi perimeter = (a+b+c)/2

The sides of the Triangle ADC is 3.54, 17.29, 17.21

and The sides of the Triangle ABD is 7.84, 17.29, 9.59

s for ADC = (3.54+17.29+17.21)/2 = 19.02

s for ABD = 17.36

A for Triangle ADC is = 30.36

A for Triangle ABD is= 9.48

The total area of the quadrilateral is 30.36+ 9.48 = 39.84

Answer: G.

Step-by-step explanation:

The formula for a circle's circumference is C = 2[tex]\pi r[/tex]

r = radius

We know the rectangle ABCD has a perimeter of 72 cm.

The rectangle is divided into 6 perimeter sides: AP, PB, BC, CQ, QD, and DA.

If we divide 6 sides to the rectangle's perimeter, we can calculate the length of one side.

72 / 6 cm = 12 cm

A side of the perimeter of the rectangle ABCD is equal to 12 cm, which means PQ, the radius of the circle is equal to 12 cm.

C = 2[tex]\pi r[/tex]

radius = 12 cm

C = 2[tex]\pi[/tex] * 12 cm

C = 2 * 12 * Pi cm

C = 24[tex]\pi[/tex]

Answer = G.

Hope I Helped!

Answer:

24pi (G)

Step-by-step explanation:

This question might seem hard at first, but we know one crucial piece of information- line PQ- is the circle's radius. We also know that Q "fits perfectly" on line DC, and that angle QPB is a right angle. Since the line is straight and passes through THE MIDDLe of the rectangle, we can assume that line PQ divides the rectangle into two squares. Since squares have 4 corresponding sides, or sides with the same length, we can rewrite the equation as x+x+2x+2x, which is 6x = 72. Apply and find your answer.

EASIER EXPLANATION:

the radius is at a right angle, meaning it divides the rectangle into two squares.

It is stated that the perimeter of the rectangle is 72, meaning if we write it into an equation where x = short sides and y = long sides.

x+x+y+y = 72

However, the long sides really equal 2x, so we can rewrite the equation

x+x+2x+2x = 72

Simplify

X+x+x+x+x+x = 72

Simplify more

6x = 72

solve

x = 12

We also know that 2x is the dimeter, which is 24.

Apply to the circumference equation

C= Dpi

Since all our answeres are in pi form, we don't need to solve

Answer:

2

Step-by-step explanation:

ist you have to lind the lcd of each fraction. that would be 10.

1/2x5/5=5/10 of the boys have brown eyes

1/5x2/2=2/10 of the boys have blue eyes

3/10=3/10 of the boys have hazel eyes

The question is asking to see how many more boys have brown eyes than hazel eyes.

Subtract 3/10 from 5/10

and that gives you 2/10

The answer is 1/5.

We know that half of the boys in Jason's class has brown eyes, while three-tenths of the boys in his class have hazel eyes. Therefore, if we subtract the two values, you should get your answer.

[tex]\frac{1}{2} -\frac{3}{10} =\frac{2}{10}[/tex]

1/5 is the simplified version of 2/10. Therefore, 1/5 is your answer.

Answer:

False

Step-by-step explanation:

The first part of the statement is correct with it saying to have an open circle on -3, but the shading should go on the right because x is bigger than -3. When you picture a number line, the numbers on the right of -3 are bigger than the numbers on the left.

The statement " To graph the inequality x > -3, draw an open circle on -3 and shade to the left" is wrong.

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

The first part of the statement is correct, as it states that an open circle should be placed on -3, but the shading should be placed on the right because x is greater than -3. On a number line, the numbers to the right of -3 are larger than the numbers to the left.
