Answer:

The third one

Step-by-step explanation:

To find the middle you have to put the numbers from least to greatest. You have 27 and 31, add them together you get 58. Now you divide 58 into 2 and answer is 29. (This one is to figure out the median)

A sequence is defined by the formula f(n+1)=f(n)-3. If f(4)=22, what is f(1)?
Vlad [161]
<h3>Answer: Choice C) 31</h3>

==============================================

Explanation:

The recursive rule

f(n+1)=f(n)-3

can be rearranged to

f(n) = f(n+1)+3

after adding 3 to both sides

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

Now let's say we plug in n = 3

f(n) = f(n+1)+3

f(3) = f(3+1)+3

f(3) = f(4)+3

f(3) = 22+3

f(3) = 25

Repeat for n = 2

f(n) = f(n+1)+3

f(2) = f(2+1)+3

f(2) = f(3)+3

f(2) = 25+3

f(2) = 28

Each time we keep adding 3 to get the previous term (since the original recursive rule says to subtract 3 to get the next term; we just go backwards of what the instructions say).

Lastly, we can find that f(1) = f(2)+3 = 28+3 = 31 making the answer to be choice C.

Helppp meeeeeeeeeeeeeee
Leni [432]

Measuring the figure with a ruler, length = 2 inch and width = 1.5 inch

It is given that 1/2 inch = 4 feet

1 inch = 4*2 = 8 feet

Area of rectangle = length * width

Length = 2*8 =  16 feet

Width = 1.5*8 =  12 feet

Area of Quintoe's bedroom = 16 feet * 12 feet = 192 feet^2

Hence option C is correct.

For the past three months Grace used her cell phone for 43 minutes 62 minutes and 57 minutes how many minutes would you have to
RSB [31]

Answer:

Grace should use her phone for 58 minutes to maintain an average of 55 minutes.

Step-by-step explanation:

Usage of first month = 43 minutes

Second month = 62 minutes

Third Minutes = 57 minutes

Let, the usage of fourth month =  k minutes

Mean of the data = 5 minutes

Now, Average of a Data =  \frac{\textrm{Sumof observations}}{\textrm{Total number of observations}}

⇒55 = \frac{43 + 62 + 57 + k}{4}

or, 55  x 4 = 162 + k

⇒    220 - 162  = k

or, k = 58 minutes

So, Grace should use her phone for 58 minutes to maintain an average of 55 minutes.

The slope of the line whose equation is x + y = 6 is<br> a. -1<br> b. 1<br> c. 6
Arlecino [84]
Let's rearrange the equation x + y = 6 to slope-intercept form. Solve for y.

x + y = 6

To get the y variable on the left-hand side alone, subtract x from each side.

x + y - x = 6 - x
y = 6 - x

Rearrange the right-hand side.

y = -x + 6

Now we have it in the slope-intercept form. And to find the slope, we look at the coefficient of x. But there is no coefficient of the -x term!

In all reality, there is. However, it's just 1. -1x is the same thing as -x. We don't show the 1 because it has no effect.

So, -1 is the slope.
