Answer: The answer for the diagram JKLM x:25

Step-by-step explanation: the diagram is a trapezium and it is made up of a triangle and rectangle. if you find the base of the triangle it will equivalent to the length of the rectangle. so the angle is 65 so we use sin to find it which will be opp/hyp. therefore sine 65=x/30,x=0.8268286949*30=24.8048603847. which is approximately 25

Find the prime factorization of 55 exponent 5 times 65 time 49 exponent 13 what is the correct answer?
igomit [66]
So 55^5 times 65 times 49^13
so this means
55 times itself 5 times times 65 times 49 times itself 13 times or 
55 times 55 times 55 times 55 times 55 times 65 times 49 times 49 times 49 times 49 times 49 times 49 times 49 times 49 times 49 times 49 times 49 times 49 times 49
so factor each
rule of exponents

55^5
55=11 times 5
55^5=5^5 times 11^5
65=5 times 13
49=7 times 7
49^13=7^26

total multiplication is 5^5 times 5 times 11 times 13 times 7^26
5^5 times 5=5^6
so prime factorization is 
5^6 times 7^26 times 11 times 13

A 12 foot board is split into 5 equal pieces. Which expression shows the length of each piece
Molodets [167]

Answer:

Find out the which expression shows the length of each piece .

To prove

As given

A 12 foot board is split into 5 equal pieces.

Than

Length\ of\ each\ piece = \frac{Total\ length\ of\ board}{Total\ number\ of\ pieces}

Here

Total length of board = 12 foot

Total number of pieces = 5

Length\ of\ each\ piece = \frac{12}{5}

Length\ of\ each\ piece = 2.4\ foot

Therefore the length of each pieces is 2.4 foot.
