Answer:

5% of 13.5 is 0.675

Step-by-step explanation:

We need to determine 5% of 13.5 now and the procedure explaining it as suchStep 1: In the given case Output Value is 13.5.Step 2: Let us consider the unknown value as x.Step 3: Consider the output value of 13.5 = 100%.Step 4: In the Same way, x = 5%.Step 5: On dividing the pair of simple equations we got the equation as under13.5 = 100% (1).x = 5% (2).(13.5%)/(x%) = 100/5Step 6: Reciprocal of both the sides results in the following equationx%/13.5% = 5/100Step 7: Simplifying the above obtained equation further will tell what is 5% of 13.5x = 0.675%Therefore, 5% of 13.5 is 0.675

Mario can paint a house alone in 3 days. ben can paint the same house alone in 5 days. how long would it take them to paint the

Elan Coil [88]

The combined time taken if Mario and Ben work together will be 1.875 days.

Time taken:

Mario alone = 3 days
Ben alone = 5 days

Work rate :

Rate = 1 / time taken
Mario's rate = 1 / 3
Ben's rate = 1/5

Their combined rate can be written thus :

Mario's rate + Ben's rate = combined rate
1/3 + 1/5 = 8/15

Time taken if they work together :

Reciprocal of combined work rate
Combined time taken = 1 ÷ 8/15 = 15/8 = 1.875 days

Therefore, the time taken of they work together is 1.875 days

See the attached diagram, it has all the information you need.

(a) If the green radii are all 1, then the orange diameters are all 2 + √2, so that the orange radii are (2 + √2)/2 = 1 + √2/2.

This is because we can join the radii of two adjacent green circles to form the sides of a square with side length equal to twice the radius - i.e. the diameter - of the green circles. The diagonal of any square occurs in a ratio to the side length of √2 to 1. Then we get the diameter of an orange circle by summing this diagonal length and two green radii, and hence the radius by dividing this by 2.

(b) We get the blue diameter in the same way. It has length (2 + √2) (1 + √2/2) = 3 + 2√2, so that the blue radius is (3 + 2√2)/2 = 3/2 + √2.
