Answer: C. 6 hours


Step-by-step explanation:

Roy worked for 2 hours and earned $12.

First you want to know how much money he made in one hour. So you divide 12 by 2.

12 ÷ 2 = $6 per hour

Now you wanna know how many hours must he work at the same rate to earn $36.


$6 × 6hours = 36

So the answer is C. 6 hours

The Sognefjord is the deepest fjord in Norway at 1,308 metres (4,291 ft) If a submersible floating on the surface was to dive ve
natali 33 [55]

Answer:

36 minutes

Step-by-step explanation:

Depth of the fjord = 1308 m

Rate at which the submersible dives = 35 meters/minute

Distance to the bottom of the fjord should be 48 m

Distance the submersible has to go underwater is 1308-48=1260\ \text{m}

Time is found by dividing the distance the submersible has to go underwater by rate at which the submersible dives

\dfrac{1263}{35}=36\ \text{minutes}

The time taken by the submersible to dive the required distance is 36 minutes.

The lowest common denominator for the fractions 8/64 and 8/32 is ?
FrozenT [24]
The lowest common denominator (LCM) is the lowest whole number divisible by both denominators without a remainder.

EASY LCM:
multiply the two denominators, then divide the total by the greatest common factor (GCF) between the two denominators.

=(64*32)/32
=2,048/32
=64

-OR-

DETAILED METHOD
STEP 1:
Find prime factors of denominators.
8/64
64: 2 x 2 x 2 x 2 x 2 x 2

8/32
32: 2 x 2 x 2 x 2 x 2

STEP 2:
If factors occur more than once, multiply them the greater number of times they occur.

2 x 2 x 2 x 2 x 2 x 2= 64

ANSWER: The LCM of 8/64 and 8/32 is 64.

Hope this helps! :)
