Answer:

648 in^2

Step-by-step explanation:

your must find the surface area of the rectangular prism

this can be modelled by

2(9 * 9) + 2(13.5 * 9) + 2(13.5 * 9)

or

2(9 * 9) + 4(13.5 * 9)

then you do whats inside the parenthesis

2(81) + 4(121.5)

and lastly you multiply and add

162 + 486 = 648

A line has a slope of 0.5<br> and passes through the point (0,5). What is the equation of the line?
EleoNora [17]

Step-by-step explanation:

Hi there!

From the question;

The slope of the line is 5/10 or 0.5.

Also the equation of the line passes through the point (0,5).

Note: Use one point formula. {i.e (y-y1)=m(x-x1)}

So, use the formula here and keep the values;

(y-5) = 5/10(x-0)

or, 10(y-5) = 5x

or, 10y-50 = 5x

or, 5x - 10y +50 = 0

Therefore, the required equation is 5x - 10y +50 = 0 or x-2y+10 = 0.

Hope it helps!

Answer:

The are 8 dimes and 12 nickels

Step-by-step explanation:

1.We set n+d=20 because 20 is the total number of dimes and nickels in the jar.We have $0.05 n because for ever nickel,we earn $0.05.Adding this to the value of dimes,represented similarly by $0.1,then we set this to the amount of money we have in total,which is $1.40.

2.Subtract d from both sides of the first equation to get it by itself.Substitute-d for n in the second equation.The divide both sides by 0.5 to obtain the answer.

3.Substitute 8 in for d to obtain the value or n.
