The triangle that is formed by AMB is a 45 45 90 triangle, so meaning the legs are equal. so in can be concluded that AD = MD, since M is the midpoint of CD, then CD = 2AD
CD = 2(6) = 12 cm
so the perimeter is of the rectangle ABCD is
P = 2l + 2w
P = 2(6) + 2(12)
P = 12 + 24
P = 26 cm
Answer:
Step-by-step explanation:
We have the length of AC which is opposite angle B; we also have the length of the hypotenuse. We will use trig here to solve for angle B. The sin ratio is the one that fits.
sin(B) = side opposite / hypotenuse:
so
sin(B) = .9411764706
Now we will use the 2nd button on our calculators. This will give us the missing angle value. Press 2nd then sin and you will see on your screen:
![sin^{-1 (](https://tex.z-dn.net/?f=sin%5E%7B-1%20%28)
Enter that decimal after the open parenthesis and hit "enter" to get
B = 70.25 or 70°
Answer:
V = 1120 cm^3
Step-by-step explanation:
Which figure?
I'll assume it's a cube.
V = l* w* h
V = 10 * 8 *14
V = 1120 cm^3
Answer:
c
Step-by-step explanation:
To find out the box number the boxes, extract the same number of balls as the number of the box, calculate the total weight.
<h3>What are the steps to find the box with the 29 kg balls?</h3>
Considering you can only weigh the balls extracted once and you need to find the box with balls that are 1-kilo lighter; here are the steps you can follow:
- Number the boxes from 1 to 19.
- Extract the same number of balls as the number given to the box. For example, from box 9 extract 9 balls.
- Weight all the balls together.
- Find out the box with the 29 kg balls. Here is an example:
The total weight using this method would be 6,300 kg which is the result of adding 30 kg (first box) + 60 kg (second box)... However, since there is a box with lighter balls the total weight will be less.
Let's imagine the weight is 6,290, this means there are 10 fewer kilos and therefore the box with the lighter balls is box 10 since this is the box number from which 10 balls were extracted.
