I think for the question above, instead of 2 · 3^2 · 7 it is <span>2 · 3^2 · 5.
</span>
Two numbers have prime factorizations of 2^2 • 3 • 5 and 2 • 3^2 • 5 (note 2 squared & 3 squared).
Now, to choose the GCF, you choose, for each base factor in either number, the least exponent-ed one; so the GCF needs a factor 2, a factor 3, and a factor 5. Thus the GCF is 30 (their product). [i.e,2 squared is not a common factor]
<span>To create the LCM, you choose, for each base factor in either number, the greatest exponented one. Thus, LCM needs a factor 2 squared, 3 squared, and 5, giving LCM = 4(9)(5) = 180.</span><span />
Answer:
x=−41−−239 =−41+4i239 =−0.2500−3.8649i x=−41+−239 =−41−4i239 =−0.2500+3.8649i
Step-by-step explanation:
11.5, when rounded to the nearest tenth the answer was 11.468 but we need to round and 6 is 5 and higher so the 4 would become a 5. The answer is 11.5
Let the number of times she turns the pedal in one mile be x.
Given that her rear miles turns 875 times in one mile and the ratio of pedal turns to rear wheel turns is 4 to 7, then
Therefore, she turns the pedal 500 times in one mile.
8% of 20 is 1.6
This is because you take the percentage and divide it by 100 so that you have a decimal, then multiply that by twenty. So, 8% ÷ 100 = 0.08 then 0.08 × 20 = 1.6
Hope this helps!
