Answer:
22738.96
Step-by-step explanation:
119.5% x 19028.42=
22738.9619
now rounded to 2 d.p is 22738.96
Answer:
5.45 hours or 5 hours 27 minutes to nearest minute.
Step-by-step explanation:
We work in rates per hour.
Kevin does 1/10 of the roof in an hour and Sam does 1/12 of the roof/hour.
Now we add to get the equation:
1/10 + 1/12 = 1 / x where x is the time they take to repair the roof working together.
Multiplying through by the LCM 60x:
6x + 5x = 60
11x = 60
x =60/11
x = 5.45 hours.
ANSWER
EXPLANATION
We use the sine rule to obtain,
We multiply both sides by 4 to obtain,
We take the inverse sine of both sides to get,
to the nearest tenth.
Carl present age is 10 years while Dennis present age is 19 years.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Let x represent Carl present age and y represent Dennis present age, hence:
x + y = 29 (1)
Also:
After 6 years:
x + 6 = y - 3 (2)
From both equations:
x = 10, y = 19
Carl present age is 10 years while Dennis present age is 19 years.
