Answer:
It takes <u>8 4/7 </u>days for both bricklayers to build the wall together.
Step-by-step explanation:
The first bricklayer takes 15 days to build the wall, which means it builds 1/15 of the wall per day.
The second bricklayer takes 20 days to build the wall, which means it builds 1/20 of the wall per day.
So if they build the wall together, the expression below will tell how much of the wall they build per day together.
1/15 + 1/20
To add the fractions, we must find a common denominator, which is 60.
4/60 + 3/60, which equals 7/60.
So, they can build 7/60 of the wall per day together. How many days will it take them? We must find how many times 7 fits into 60, which can be done by solving 60/7, which is 8 4/7.
So, it takes 8 4/7 days for both bricklayers to build the wall together.
The height of lighthouse is 52.2 yards
<em><u>Solution:</u></em>
Given that photographer stands 60 yards from the base of a lighthouse and observes that the angle between the ground and the top of the lighthouse is 41 degree
The diagram is attached below
Consider a right angled triangle ABC
AB is the height of the lighthouse
BC is the distance between the base of a lighthouse and Photographer
As per given, BC = 60 yards
Angle between the ground and the top of the lighthouse is 41 degree
Angle ACB = 41 degree
<em><u>To find: height of lighthouse i.e AB = ?</u></em>
We know that,

Here Base is BC and perpendicular is AB

Substituting the values,

Thus the height of lighthouse is 52.2 yards
Answer:
The equation to determine the salary every given number of weeks is 14x2 ^ X = Y, and after 12 weeks, the counselor's salary will be $ 57,344.
Step-by-step explanation:
Since the initial starting salary for a summer camp counselor is $ 14 per week, and starting with the first week, the salary doubles to encourage the counselor to work for the entire summer, to write an equation that models the salary (y) of the camp counselor per week (x), and determine, if the camp runs for 12 weeks, how much would a camp counselor make, the following calculations should be performed:
14x2 ^ X = Y
14x2 ^ 12 = Y
14x4,096 = Y
57344 = Y
Therefore, the equation to determine the salary every given number of weeks is 14x2 ^ X = Y, and after 12 weeks, the counselor's salary will be $ 57,344.
