The net on the left is correct.
surface area is the sum of all side areas.

15*5 = 75
5*12 = 60
15*12 = 180
15*13 = 195

75 + 60 + 180 + 195 = 510

15*3=45
5*2=10
12*2=24
13*2=26
10+45+24+26=105

A n =−1+3(n−1) an=−1+3(n−1) what is the 55 term in the sequence

Sindrei [870]

ANSWER

$a_{55}=161$

EXPLANATION

The general term for the sequence is

$a_n=-1+3(n-1)$

To find the 55th term, we have to substitute
$n = 55$
in to the general term and simplify.

This implies that,

$a_{55}=-1+3(55-1)$

$a_{55}=-1+3(54)$

$a_{55}=-1+162$

$a_{55}=161$

Therefore the 55th term is 161.

How do you invert and multiply to divide 2/3÷4

Ira Lisetskai [31]

2/3 ÷ 4

2/3 ÷ 4/1

We invert the 4/1 to 1/4 and multiply out.

2/3 × 1/4

= 1/3 × 1/2 2 into 4 is 2.

= 1/(3 × 2)

= 1/6

Hope this helps.

Will give brainliest answer to whoever gets this correct.

yanalaym [24]

draw an imaginary line down from the 1 dimension so you have a rectangle that is 1 by 24

area = L x w = 24 * 1 = 24 square units

now you have a triangle that is 7 at the bottom and 24 tall

area of triangle = 1/2 x base x height

so you have 1/2 * 7 * 24 which =84 square units

total area = 84 + 24 = 108 units^2

Help me find a trend line for the data.

Hatshy [7]

A linear equation of the trend line that models the data points contained in the table is y = 0.09x + 16.27.

<h3>How to find a trend line for the data?</h3>

In order to determine a linear equation of the trend line (line of best fit) that models the data points contained in the table, we would have to use a scatter plot.

In this scenario, the body weight (in lbs) of the high school students would be plotted on the x-axis of the scatter plot while the backpack weight (in lbs) would be plotted on the y-axis of the scatter plot.

On the Excel worksheet, you should right click on any data point on the scatter plot, select format trend line, and then tick the box to display an equation for the trend line (line of best fit) on the scatter plot.

From the scatter plot (see attachment) which models the relationship between data points in the table, a linear equation of the trend line is given by:

y = 0.09x + 16.27
