Answer:
This is a right triangle, so we know that:
h² = b' · c'
which is this case can be specificly written as:
BD² = AD · CD
BD² = 7 · 3 = 21
BD = √21
Now that we can also notice that ΔADB is also a right triangle, therefore we can apply the pythagorean theorem:
AD² + BD² = AB²
7² + (√21)² = x²
x² = 49 + 21 = 70
x = √70
Answer:
1. 260 years
2. 3/6 I think I'm not sure
3. 5:30
4. 50 kg (I think)
5. 5 ft ( 54 in. = 4.5 ft)
6. x = 4
7. 9
8. false
9. Perpendicular
10. 40
This is a simple programming question. To calculate the average of any two numbers, where one number is 1 and the other is n, simply add the two numbers and divide by 2. Therefore, the answer is:
<span>avg = (1 + n) / 2</span>
Answer:
9, 40 and 41
Step-by-step explanation:
All right triangle have lengths that follow the Pythagorean Theorem (a²+b² = c²). Right triangles have one angle equal to 90°. The two shorter sides form the right angle and the side opposite the right angle is called the hypotenuse.
Using the lengths given, we can use guess and check to see what sum of two sides squared would equal a third side, or just plug them into the equation: a²+b² = c² and see what lengths fit this equation.
I recommend starting with squares you are familiar with:
9² + 40²= 81 + 1600 = 1681
Now, take the √1681 to find the length of 'c', or the hypotenuse:
√1681 = 41
Since these three lengths fit the Pythagorean Theoreom, the would form a right triangle.
So 5
then 5 times 5
then 5 times 5 times 5
so it seems that for x rounds, there will be 5^x
A: 4 rounds so 5^4=625 photos
B. see how many times 5 goes into 78125. the answer is 7 so 7 rounds
C. 1 million=1,000,000 so try big numbers
5^10=9,765,625 too big
5^9=1,9,53,125 too big
5^8=390625 too small
the minimum is 5^9 or 9 rounds
A:4
B:7
C:9
