What Is The Length Of Side BD?

Mathematics
1 answer:
emmainna [20.7K]3 years ago
8 0
This is a rectangle, meaning that all angles are right angles and all sides opposite to one another have equal length.

Since the length of CD is 24, the length of AB must also be 24.
Angle B is a right angle because this is a rectangle.

See anything? I'll you a hint. We have a right triangle with only one missing value.

What do we use to solve for missing lengths in a right triangle? The Pythagorean theorem, of course!

a^2+b^2=c^2

The length of c (the hypotenuse) is 26.
The length of a (one leg) is 24.
The length of b is unknown and we want to find it.

24^2+b^2=26^2

576+b^2=676

Subtract 576 by both sides.

b^2=100

Take square root of both sides.

b=10

The length of the missing leg is 10, meaning that the length of BD is 10.

This is what you should be needing. Enjoy!

2) A product originally costs $125. If the product goes on sale for 20% off, and then goes on sale for an additional 30% off, wh
alukav5142 [94]
To do these, always convert the percents to decimals, so you can subtract it from 1. Remember, 1 is the whole. When you subtract the part that's taken off, you are left with what you have to pay. If you have 20% off of $100, then you are paying for 80% of $100. **of means to multiply** so you would multiply: 0.8X100, which would be $80.

First, multiply 125x0.8

Multiply that answer by 0.7

You should get B. $70

3) multiple 22.90x0.93

You should get D

Answer:


Step-by-step explanation:

11) Profit = Selling price - purchase price - other expenses

= (2000*7)-12780-26=1194

12)  Profit = Selling price - purchase price - other expenses

=52.25(550)-28275-32=430.50=430(after rounding off)

13) Annual interest on bond

=INterest rate on face value of bond for 1 year

=2000(6%)=120

14)Cost of bond

= quoted value (rate)

=3500(80.5)

=2817.50

15) Cost of bond

= quoted value (rate)

=4250(83.5)

=3548.75
