This can be treated as a work problem and we can solve it as follows:
Harland working alone = 15 minutes
Trudy scatters the leaves + Harland rakes = 20 minutes
We set scattering as a negative value.
1/15 - 1/x = 1/20
x = 60 minutes for Trudy to scatter the leaves alone
Answer:
Step-by-step explanation:
Take the beginning number and add or subtract each transaction to get a new balance. For example,
349.45
- 23.42 = 326.03
- 14.95 = 311.08
+ 276.50 = 587.58
- 219.93 = 367.65
- 76.84 = 290.81
Answer:
51
Step-by-step explanation:
Given parameters:
Number of heads = 30 heads
Number of legs = 84 legs
Unknown:
Number of chickens and pigs = ?
Solution:
Since a chicken has one head, the number of chicken is the same as the number of heads;
Number of chicken = 30
A pig has 4 legs,
Number of pigs =
= 21pigs
Total number of pigs and chickens = 30chickens + 21 pigs = 51
Now that must be an interesting wall
um
what is the question
I don't know but
the equation for a triangle's area is
(base times height) divided by 2
Answer:
49/144
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 49 and 144 is 1
Divide both the numerator and denominator by the GCD
49 ÷ 1
144 ÷ 1
Reduced fraction:
49
144
Therefore, 49/144 simplified to lowest terms is 49/144.
