Two numbers are relatively prime if they have no common divisors other than 1. This is the case only for a) , the common divisor in other cases is:
b: 3
c: c
d: 18
The relation between the legs and the hypotenuse of the right-angled triangle can be expressed using the Pythagorean theorem as follows:
We are given that a and b are the legs and we need to compute the hypotenuse. This means that all we need to do is substitute in the above formula.
<u>Question 7:</u>
a = 6 and b = 8
hypotenuse = units
<u>Question 8:</u>
a = 5 and b = 9
hypotenuse = units which is approximately 10.3 units
<u>Question 9:</u>
a = 4 and b = 10
hypotenuse = units which is approximately 10.8 units
<u>Question 10:</u>
a = 9 and b = 1
hypotenuse = units which is approximately 9.1 units
<u>Question 11:</u>
a = 7 and b = 3.5
hypotenuse = units which is approximately 7.8 units
<u>Question 12:</u>
a = 1.4 and b = 2.3
hypotenuse = units which is approximately 2.7 units
Hope this helps :)
C) 54 is correct
Multiply all numbers! Mark with crown!
Answer:
no
Step-by-step explanation:
a^2 +b^2 = c^2
c^2 - a^2 = b^2
12^2 - 5^2 = b^2
144-25 = b^2
199 = b^2
sqrt(119) = b
10.9 = b
a = distance from the wall = 5
c = length of the ladder = 12
Q4 (a): •128 can be written as 2^7
• so 2^2a-1 = 2^7
• move 1 to the other side making it 7+1 which = 8
so no 2^2a = 2^8
divide 8 by 2 which gives 4
so a=4
