Answer:

First, make the double negative a positive.

So, (-6/13) + (7/15)

Then multiply the numerator, 6×7=42

And denominator 13×15=195

42/195 simplify by dividing both by 3 so 14/65

Answer:

Step-by-step explanation:

given:  -6/13 - (-7/15)

= -6/13 + 7/15

= (-6/13)(15/15) + (7/15)13/13)

= -90/195 + 91/195

=  - 1/195

A GE Lightbulb is suppose to last for 1200 hours. In fact light bulbs of this type last only 1,185 hours with a standard deviati
Andre45 [30]
This can be solved using the formula for t test which is = x - mu over standard deviation divided by the square root of the number of samples. In this case, it is 1185 - 1200 over 70 divided by square root of 100 which give us a value of 2.14 which is equal to .9839 in area. Only rarely, just over one time in a hundred tries of 100 light bulbs, would the average life exceed 1200 hours.

Evaluate the following expression. (8 ^1 ) 0<br><br> A) 0<br> B) 1<br> C) 8
Mice21 [21]
Given that the equation looks like: (8^1)0

This means that our first step is to do what is in Parenthesis. 8^1 is = to 0

This means our equation now looks like:
(8)0

When you multiply anything by zero, it becomes zero.

This means your answer should be A.0

A building in a city has a rectangular base. the length of the base measures 65 ft less than twice the width. the perimeter of t
dybincka [34]

By solving a system of equations, we will see that the width is 170ft and the length 275 ft.

<h3>How to get the dimensions of the base?</h3>

For a rectangle of length x and width y, the perimeter is:

P = 2*(x + y).

Here we know that:

x = 2y - 65ft

p = 890ft = 2(x + y)

So we have a system of equations.

To solve this, we need to replace the first equation into the second one:

890ft = 2(x + y)

890ft = 2(( 2y - 65ft) + y)

Now we can solve this for y.

890ft = 4y - 130ft + 2y

890ft + 130ft = 6y

1020ft/6 = y = 170ft

So the width is 170ft, and we know that:

x = 2y - 65ft = 2*(170ft) - 65ft = 275ft

So the length is 275 ft.
