the answer will be 98
Step-by-step explanation:
Answer:
k = 13
Step-by-step explanation:
20 ^ k / 20^4 = 20^9
knowing the laws of exponents, diving two numbers of the same base with exponents is like subtracting the exponents, so
k^x / k^y
= k ^ (x - y)
apply that knowledge here
20 ^ k / 20 ^ 4 = 20 ^ 9
20 ^ ( k - 4 ) = 20 ^ 9
now the bases have no use here so ignore them, and just calculate the exponents
k - 4 = 9
solve using inverse operations
k - 4 = 9
+4 +4
k = 13
Answer:
1/4 pound
Step-by-step explanation:
The maximum error is half the "rounded to" value. Here, rounding is to 1/2 pound, so the maximum error is 1/4 pound.
Answer

_ ×(-63x-52)
2
Step-by-step explanation:
Answer:
It is 27.4
Step-by-step explanation:
First you need to find the area of the three rectangle.
Area=base*high
You do 4*2 for about 3 times
Which is 8 for 4*2
Then you multiply it 3 more time and get 24.
After that you add 24+1.7+1.7 and get 27.4
