Answer:
25 and 21 hours respectively
Step-by-step explanation:
Let the number of hours worked by each welder be x and y respectively.
They worked a total of 46 hours. This means :
x + y = 46 hours.......(I)
Now, given their hourly charges, since we have the total amount of money realized, we can make an equation out of it. This means:
34x + 39y = 1669........(ii)
We then solve both simultaneously. From I, x = 46 -y
We can substitute this into ii
34(46 -y) + 39y = 1669
1564 -34y + 39y = 1669
5y = 1669 - 1564
5y = 105
y = 105/5 = 21
x = 46 - y
x = 46 - 21 = 25 hours
The numbers of hours worked by the welders are 25 and 21 respectively
Given:
Right Rectangular Prism.
It has its length, width, and height.
Surface area of a right rectangular prism has this formula:
SA = 2 (wl + hl + hw)
Volume of a right rectangular prism has this formula
V = whl
Formula of Surface Area is different from Volume.
Surface
area measures the area the whole rectangular prism surface. It computes
for the area of all 6 faces that a right rectangular prism has.
Volume measures the area within the rectangular prism. It is the space that is enclosed within the rectangular prism.
