Answer:
Maria is 66" tall, Juan is 51" tall
Step-by-step explanation:
There are 12 inches to a foot.
Luis is 62" tall
Maria is 1/3 of a foot taller than Luis, 1/3 of 12 is 4, (multiply 12 by 1/3)
So Maria is 4 inches taller than Luis, making her 66" tall
Juan is 1 1/4 feet shorter than Maria, that's one foot and 1/4 of a foot shorter, 1/4 of 12 is 3 (multiply 12 by 1/4)
So Juan is one foot (12 inches) plus 3 more inches shorter than Maria,
Juan is 15 inches shorter than Maria, making him 51" tall
Answer:
<em>Number of nickels = 6</em>
<em>Number of dimes = 14</em>
<em>Number of quarters = 23</em>
<em></em>
Step-by-step explanation:
Total number of coins = 43
Let number of nickels = n
Let number of dimes = d
Let number of quarters = q
Money in n nickels = 
Money in d dimes = 
Money in q quarters = 
Total money = $7.45
The sum of the numbers of nickels and dimes is 3 less than the number of quarters.
i.e.
Let us put the value in (1):
Putting the value of q in (1) and (2):
n+d = 20 .... (3)
(4) - (3):
d = 14
Now, from (3):
n = 6
<em>Number of nickels = 6</em>
<em>Number of dimes = 14</em>
<em>Number of quarters = 23</em>
Answer:
Robert earned $23 for each lawn that he mowed.
Step-by-step explanation:
Identify what you know:
1) Robert earned a total of $184 dollars for mowing 8 lawns
2) He was paid the same amount for mowing each of the eight lawns.
So, let's write our equations, where x equals the total that he was paid for one lawn.
$184/8 = x
OR
x times 8 = $184
We can reverse engineer both problems!
$184 divided by 8 = $23
D = rt
We are given the rate r to be 15 mph.
We are given the time (in hours) to be 3.5.
We need to find D.
D = (15)(3.5)
D = 52.5 miles.
