She gets to the library at 5:30. Half an hour is equal to 30 minutes, and if she leaves at 5:00, she will be there in thirty minutes.
If Jeff writes comic strips at a rate of 3 comics an hour then you must put 3,4,7&9 into the function and add up the products.
9+12+21+27=69
(3 hours) / (8 friends) = <em>3/8</em> hour per friend
Answer:
A, B and C (close examination)
Step-by-step explanation:
A. 15m3 - 6m = 3m(5m2 - 6m)
B. 40m6-4=4(10m6-1)
- 0 = 0
- All real numbers are solutions
C. 6m2+18m=6m2(1+3m)
D. 32m4+12m3(8m+3)
This is tough one but I will explain this problem by close examination:
The problem is looking for an equation that have the variable m by itself
D is out of the picture because the equations does not have m by itself
Equation B's answer is that all numbers are solutions meaning any m value you put will become the same. (Similar to Infinite Solutions)
By close examination, The answer are A, B, and C.
Answer:
Perimeter: 18 ft
Height: 7 ft
Base Area: 12
Surface Area: (7)*(8) + 2(47) = 150
Step-by-step explanation:
To find the perimeter add all the edges together.
5 + 5 + 8 = 18
To find the height look at the diagram. 7ft shows the height of the rectangle and thus is the height for the rest of the shape.
Base Area:
Multiply the length (8ft) of the base by the height of the base (3ft)
8 * 3 = 24
Then divide by 2 to get the total area of the triangle
24 / 2 = 12.
Surface Area:
To find the surface area you to need to find the specifics of each side.
The base area we already solved for which is 12. We'll get back to this in a minute. The other double sides are of 5 * 7. That equals 35. Add together 12 + 35 to get 47. That is what will go in the 2(___) box because both of those sides have 2. It is the same number when done this way versus just adding them up.
47 * 2 = 94
12 + 12 + 35 + 35 = 94
Then for the (___)(___) that would be 7ft * 8ft because it is the only side left and does not have a double so it must be separate.
7 * 8 = 56
56+94 = 150
