Answer:

z=28

Step-by-step explanation:

6=1/4z-1

1) take the -1 over to the other side of the equation, so it becomes +1

2) 6+1=7, so your new equation is 7=1/4z

3) to get "z" on its own, you'll have to time the 7 by 4 which is 28

4) your equation is now 28=z and that is your answer.

You can check by inserting 28 instead of z into the equation and it gives you 6. E.G. 1.4 X 28 -1 =6

Answer:

61

Step-by-step explanation:

mean formula: sum of all terms/number of terms

sum of all terms: 366

    31

    55

+   68

    70 70 72

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

TOTAL: 366

number of terms: 6

31, 55, 68, 70, 70, 72

366/6 = 61

Answer:

24

Step-by-step explanation:

In a stem-and-leaf plot, each leaf represents a number or piece of data.

Each the leaf will only show the last digit of the number, and the stem will have the rest.

Examples:

stem value of 1 with a leaf value of 2 = 12

a stem value of 3 with a leaf value of 0 = 30

So, this is your plot:

Stems| Leaves

 1      |   2  3  5

 2     |   8  8

 3     |   0

 4     |   2

Your data is 12, 13, 15, 28, 28, 30, 42.

Add up all these numbers and divide by the number of leaves.

Sum of data = 12 + 13 + 15 + 28 + 28 + 30 + 42 = 168

Number of leaves = 7

168 ÷ 7 = 24

The mean is the values in the stem-and-leaf plot is 24.

Answer:1/36

Step-by-step explanation:

Since the first one has a 1/6 chance because it is a 6-sided dice, and the second roll has to be 1/6. Once you multiply 1/6 by 1/6 you get 1/36

Answer:

Step-by-step explanation:

so since it is $40 per month for 12 months we would have to multiply 40x12 and that would give you $480

Answer:

D

Step-by-step explanation:

to find which ordered pair is a solution to the equation.

substitute the x- coordinate into the right side of the equation and if the value obtained is equal to the y- coordinate then the ordered pair is a solution.

A (0, 0 )

y = - 3(0) - 5 = 0 - 5 = - 5 ≠ 0 ← not a solution

B (- 1, 8 )

y = - 3(- 1) - 5 = 3 - 5 = - 2 ≠ 8 ← not a solution

C (1, - 2 )

y = - 3(1) - 5 = - 3 - 5 = - 8 ≠ - 2 ← not a solution

D (1, - 8 )

y = - 3(1) - 5 = - 3 - 5 = - 8 ← solution

then (1, - 8 ) is a solution to the equation

Answer:

D. (1, -8)

Step-by-step explanation:

Given: y = -3x - 5

Using substitution, we can substitute the given value of coordinates into the equation to see which coordinate makes a true statement.

A. (0, 0)

0 = -3(0) - 5

0 = -5

This is a false statement.

B. (-1, 8)

8 = -3(-1) - 5

8 = 3 - 5

8 = -2

This is a false statement.

C. (1, -2)

-2 = -3(1) - 5

-2 = -3 - 5

-2 = -8

This is a false statement.

D. (1, -8)

-8 = -3(1) - 5

-8 = -3 - 5

-8 = -8

This is a true statement.

Therefore, the correct answer is D.

Answer: There will be 16,777,216 bacteria by the end of the day.

Step-by-step explanation: This situation can be represented by a geometric sequence, in which the quotient of consecutive terms is always the same, called the common ratio.

The nth term of a geometric sequence is:

In which is the term at the initial moment and q is the common ratio.

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

Initially, 1 bacteria, which means that

Double every hour, thus,

After n hours, the number of bacteria will be given by:

By the end of the day, that is, 24 hours, the amount will be:

There will be 16,777,216 bacteria by the end of the day.

Answer:

He needs to score a 19

Step-by-step explanation:

First, I found the mean of the three test scores. The mean was below 17 so I knew he needed a grade higher than the ones he already has. So I went up from 18. So my first equation was 15+18+16+19=68. then I divided by 4 which gives you a mean of 17. (Mean=average)

Answer:

= 3 (3x + 5y)

Step-by-step explanation:

First find the GCF of 9 and 15 which would be 3. Then the GCF which is 3 is placed on the left of the parentheses. then you plug in the numbers. So 9x divided by 3 is 3x, and 15y divided by 3 is 5y.

               Factor the expression 9x+15y using the GCF.

[tex]\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}[/tex]

First, let's find the GCF of this expression.

Expressions, like numbers, have GCF's, and we're asked to find it.

The factors of the first term, 9x, are:-

1, x, 3

The factors of the second term, 15y, are:-

1, y, 3, 5

Common factors:-

1, 3

Greatest common factor (GCF):-

3

So we divide both terms by 3:-

3(3x+5y)

Answer:

154

Step-by-step explanation:

bc z is striaght line = 180

so 180 -26 = 154

remember

y + 26 = z

Answer:

∠y = 154°

Step-by-step explanation:

- angle ∠z is a straight angle meaning it equals 180 180°

this is also known as...

supplementary angles (when two angles whose sum is 180°)

- one of the two angles are given:

angle 1: 26°

angle 2: ∠y °

26 + ∠y = 180 °

subtract 26 from both sides to get y alone

26 -26 + ∠y = 180 ° - 26

∠y = 154°

∠y is an obtuse which is confirmed by 154°
