Answer:

{10, -8} (A)

Step-by-step explanation:

Since it is absolute value, n-1 can equal both 9 or -9.

First you solve for n-1=9.  That would make n=10

Then you solve for n-1= -9 .That would make n=-8

Answer:

A) {10, -8}

Step-by-step explanation:

Since it is absolute value, you must split it into two equations:

n-1=9

n-1=-9

Now solve for n in both equations

n=10

n=-8

Therefore, the answer is A

Answer:

36

Step-by-step explanation:

Let Brandon's age be b. We can write 4b = b + 27 which gives us b = 9. Because Michael is 4 times as old as Brandon, he is 9 * 4 = 36 years old.

Answer:

36

Step-by-step explanation:

Micheal is 4 times as old as Brandon.

y = 4x

Micheal is also 27 years older than Brandon.

y = x +27

Y represents Micheal's age, and x represents Brandon's age.

Since both equations above are equal to the same value, y, you can set the two equations equal to each other.  Solve for x.

4x = x + 27

3x = 27

x = 9

Brandon is 9 years old.  

Plug Brandon's age into one of the equation to solve for Micheal's age.

y = x + 27

y = 9 + 27

y = 36

Micheal is 36 years old.

Answer:

3 < 5

Step-by-step explanation:

3 < 5

We can write this inequality, because three is less than five, and < means less than.

An inequality is a mathematical sentence which

states that two expressions are not equal.

The "<" symbol means less than.

Since 3 is less than 5, we can write this as 3 < 5.

Take a look below I have attached the same problem

Answer:

5/6

Step-by-step explanation:

On a standard 6-sided die, there is only one 2. That means that there are 5 other numbers that it could land on (1, 3, 4, 5, 6).

Using that information, the probability of it not landing on a 2 is 5 out of 6 or 5/6. This is because you must do part over whole. The "part" in this situation is the 5 "wanted" numbers, and the "whole" is 6 because there are six potential numbers that it could land on.

I hope this helps.

The probability that it will not land on a 2 is 5/6

Probability is the likelihood or chance that an event will occur.

It will land on 2, Prob (land on 2) = 1/6

It will not land on 2, the probability will be given as:

Prob (not land on a 2) = 1 - 1/6

Prob (not land on a 2) = 5/6

Hence the probability that it will not land on a 2 is 5/6

Step-by-step explanation:

Let's call the angles 2x, 3x, 5x and 8x and since the sum of angles in a quadrilateral is 360 degrees we can write:

2x + 3x + 5x + 8x = 360

18x = 360

x = 20 which means the angle measures are 40°, 60°, 100° and 160°

Answer:

40°,60°,100° and 160°

Step-by-step explanation:

First add all the ratio's together

2 + 3 + 5 + 8 = 5 + 13 = 18

Now we utilise the fact that angles in quadrilaterals add up to 360. We form an equation like this 18x = 360 to find the value of x and then substitute back into the ratio's

18x = 360

→ Divide both sides by 18 to isolate x

x = 20

Multiply 20 by each of the ratio's to find the angles of this quadrilateral

2 × 20 = 40

3 × 20 = 60

5 × 20 = 100

8 × 20 = 160

So the angles of a quadrilateral with the ratio of 2: 3 : 5 : 8 is 40,60,100 and 160

Answer:

S(t) = 10 - 0.5t

Step-by-step explanation:

initial depth of snow = 10 inches

melting rate =  0.5 inches per hour

it means that, in one hour snow depth will decrease by 0.5 inches

thus , in t hours  snow depth will decrease by 0.5*t = 0.5t inches

Thus, depth of snow after t hours can be calculated by

we will take initial depth of snow and them subtract the depth of snow which melted in t hours.

we are subtracting as snow is melting and will thus decrease the depth of snow

depth of snow after t hours can = initial depth of snow - decrease of the depth of snow after snow melts for t hours

depth of snow after t hours can = 10 inches - 0.5t inches

                                                       =  (10 - 0.5t )inches

Thus ,S(t), representing the depth of snow on Mason's lawn, in inches, t hours after the snow stopped falling is S(t) = 10 - 0.5t

Answer:

5

Step-by-step explanation:

4a + 6b = 24

6a - 12b = -6

Rewrite the first equation below. Divide both sides of the second equation by 2 and write below the first equation. Then add the equations.

      4a + 6b = 24

+     3a - 6b = -3

----------------------------

      7a         = 21

Divide both sides by 7.

a = 3

Now substitute 3 for a in the first equation and solve for b.

4a + 6b = 24

4(3) + 6b = 24

12 + 6b = 24

6b = 12

b = 2

a = 3, and b = 2

a + b = 3 + 2 = 5

Answer:

C

Step-by-step explanation:

this is because perpendicular lines have the opposite reciprocal slopes. So, 3/2 is the opposite reciprocal of -2/3 since it is negative and that is the opposite sign. Then, it is the reciprocal of the fraction since the numerator and the denominator are switched. If you check the other answer options, you will see that none of the slopes are the exact opposite reciprocal.

Answer:

Length of the fencing required = 201.06 meters

Step-by-step explanation:

Architect is planning a circular playground with diameter = 64 m

We have to calculate the fencing required to cover this playground.

Length of fencing = circumference of the playground

Since circumference of a circle = π × (Diameter)

                                                    = 64π

                                                    = 201.06 meters

Therefore, length of fencing required to keep the kids in a circle will be 201.06 meters.

Example A

How many ways can 5 students sit in a row?

Solution: If we consider the students sitting in one of five seats, then we have 5 students to choose from for the first seat, four remaining to choose from for the second seat and so on until all the seats are filled.

5–×4–×3–×2–×1–=120 So there are 120 ways to seat the students.

More Guidance

The way we just wrote out 5–×4–×3–×2–×1– can also be expressed as a factorial. A factorial is the product of a number with each number less than itself. We use the notation, 5!, which is read as “five factorial” to represent the expression 5–×4–×3–×2–×1–. It is important to note that 0!=1!=1. Students are often perplexed that both zero and one factorial are equal to one but think back to the context for illustration. If you want to arrange zero items, how many ways can you do it? If you want to arrange one item, how many ways can you do it? There is only one way to “arrange” zero or one item.
