Answer:
12.5%
Step-by-step explanation:
105 is what percent of 120?
you can use this proportion:
if/of = %/100
in this problem:
is = 105
of = 120
'what percent' = p/100
105/120 = p/100
cross-multiply to get:
120p = 10500
p = 10500/120
p = 87.5
So the electrician used 87.5%, out of 100%, meaning 12.5% went unused
Answer:
343
Step-by-step explanation:
7³ = 7 × 7 × 7
= 343
The answer is A. If you use synthetic division to solve. You get the remainder of 0 therefore its A
We will use the equation:
r t = 3/4 r ( t+12 ) /:r
t = 3/4 t + 9
t - 3/4 t = 9
1/4 t = 9
t = 9 * 4 = 36 minutes ( takes a trip to the market )
36 + 12 = 48 minutes
The ride home takes 48 minutes.
Answer:
The two equations are;
w = 52 h
and h = w/52
Step-by-step explanation:
From the question, we are told that she earns $52 in an hour
So therefore ,
W(h)= 52h
where h is the number of hours she has worked and w is the wages earned for the number of hours worked
The two equations are;
w = 52h
or w/h = 52
