Answer:

3\sqrt{5}/2

Step-by-step explanation:

As given, AC = BC, its an isosceles triangle.

Now, CD is perpendicular to AB, therefore AD = DB = 0.5AB = 3/2

Now take triangle ACD,

using Pythagoras theorem,

AC = \sqrt{AD^{2} + CD^{2}   }

AC = 3\sqrt{5}/2

b)  Draw a rectangle of sides 9 cm by 1 cm. Divide the rectangle into nine equal parts. Shade seven out of the nine parts to give the fraction 7/9

c)  Draw a rectangle of sides 12 cm by 1 cm. Divide the rectangle into twelve equal parts. Shade ten out of the twelve parts to give the fraction 10/12

d)  Draw a rectangle of sides 12 cm by 1 cm. Divide the rectangle into twelve equal parts. Shade eight out of the twelve parts to give the fraction 8/12

e)  Draw a rectangle of sides 5 cm by 1 cm. Divide the rectangle into five equal parts. Shade four out of the five parts to give the fraction 4/5

The total amount of deductions from an employee’s gross pay is $83.20. If the gross pay is $378.18, what percent of their gross
Masja [62]

Answer:

22%

Step-by-step explanation:

A percent of something can be thought of as part of that thing divided by the total amount of the same thing and multiplied by 100%.

In this case, the part of the thing is part of a paycheck. The total thing is the total paycheck.

Percent=\frac{Part}{Total} *100%%

Percent=\frac{83.20}{378.18} *100=0.2200*100=22.000%
