Answer:
48 square unit
Step-by-step explanation:
For a rectangle, area is given by
A=bh
Where b is base and h is height as shown in the attached diagram
For a triangle, area is given by
A∆=½bh
Given that ½bh=48
Then bh=2*48=96 square units
The overall area is 96 square units.
The area for 1&2 combined will be given by deducting the area of triangle from the overall area
Area is 96-48=48 square units
The data about the number of minutes per day is so confusing. I'll just answer it based on what I understood from the data provided:
Monday: 480 minutes
Tuesday: 450 minutes
Wednesday: 495 minutes
Thursday: 480 minutes
Friday: 300 minutes
We need to add up all the minutes worked for the week:
480 + 450 + 495 + 480 + 300 = 2,205 minutes
2,205 minutes / 60 minutes = 36.75 hours
36.75 hours is less than the maximum number of hours worked in a week which is 40 hours.
36.75 hours translates to 36 hours and 45 minutes of work for the week.
Let candy bars =xLet drinks =y Set up the two equations. 60x + 110y = 265120x + 90y = 270 Solve through elimination. Multiple the first equation by 2 and subtract the second equation from the first. When we multiply the first equation by two, we get: 2(60x +110y = 265) = 120x + 220y = 530 Then, when we subtract the second from the first we get: (120x + 220y = 530) - (120x +90y = 270) The result is 130y = 260 So, y=2 Then, we plug that back in to the original equation to find x. 60x + 220 = 265 Subtract 220 from both sides. 60x = 45 x = .75 So, drinks cost 2 dollars and candy bars cost 75 cents.
Hope this helps! :)
"deci" means ten. So 3x10 = 30. With this information the answer is obvious that it is equal not more than.
ANSWER
B. infinite solutions
EXPLANATION
We want to solve the equation;
and
We multiply the second equation by 3 to get:
We now subtract equation (1) and (3).
This implies that
Hence the equation has infinitely many solutions.
