As the only prime factor of denominator is
2
, in fact there are three twos (
2
×
2
×
2
) we can can convert the fraction
7
8
by multiplying numerator and denominator by
5
×
5
×
5
.
Hence,
7

=

=

1000
=
0.875
(This is always possible if only prime factors of denominator are
2
's and
5
's - just multiply by as many
5
's and
2
's).

2800*0.15= 420
Answer:
m=5
Step-by-step explanation:
1. Convert the logarithm into exponential form using the fact that 
(x)=b is equal to x=
so ... 4m-10=
2. Any expression raised to the power of 1 equals itself so ... 4m-10=10
3. Move the constant to the right-hand side and change its sign so ... 4m=10+10
4. Add the numbers so ... 4m=20
5. Divide both sides of the equation by 4 so ... m=5, m>
6. Check if the solution is in the defined range so ... m=5
Answer:
1:12 One sketch every 12 minutes. Four Easy Steps Below!
Step-by-step explanation:
The ratio will be sketches:minutes
*We try to find how many minutes it takes him to make 1 sketch, since it's asking for lowest terms!
- find the larger ratio= 5:60 *60 minutes in an hour, we're finding minutes! Convert one hour to minutes*
- 5:60.... Divide 60 by 5. *You're finding the time it takes for one sketch*
- 12
- 1:12 1 sketch every 12 minutes. This is the lowest term.
