Answer:

The expression is : 20(15+35)-300

Step-by-step explanation:

Every week for 20  weeks, Kathy earned $15  for mowing lawns and $35 for delivering newspapers.

In 20 weeks, the earnings from mowing lawns will be = 15*20

In 20 weeks, the earnings from delivering newspaper will be = 35*20

At the end of 20 weeks she spent $300 and was left with :

(15*20+35*20)-300 dollars

Or can be written as : 20(15+35)-300 dollars

This is the expression to solve the problem.

The diagram shows a 5 cm x 5 cm x 5 cm cube.
Nitella [24]

Answer:

8.7 cm

Step-by-step explanation:

The question is a 2-two-step Pythagoras theorem. (c^2 = a^2 + b^2)

Consider as such, If I were to draw a diagonal line along the base of the cube what is the length of the diagonal line. To find out that we use the theorem. We can substitute a for 5 and b for 5 as well. So

a^2 +b^2 = c^2

5^2 + 5^2 = c^2

25 + 25 = c^2

√50 = c

Then since the line side of the cube is on a 3d angle we need to do the same process again but now using the imaginary diagonal line that we just calculated and the height (5).

a^2 +b^2 = c^2

√50^2 + 5^2 = c^2

50 + 25 = c^2

√75 = c

c = 8.6602...

<em>when rounded to 1 d.p.</em>

c = 8.7

Line AB is 8.7 cm long.
