I think using a computer software would be the best answer because it is then fair
Hi there!
If Bruce reads for 3/4 of an hour each night and he wants to know how long he'll have read in 4 nights, then we'll need to do some multiplication. We need to multiply 3/4 * 4/1. Multiply straight across to get 12/4, which simplifies to 3 hours in 4 nights.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
136 units²
Step-by-step explanation:
The surface area (SA) is calculated as
SA = area of base + area of 2 congruent sloping faces + area of 2 triangular ends
area of base = 6 × 7 = 42 units²
area of sloping faces = 2 (7 × 5) = 2 × 35 = 70 units²
area of triangular faces = 2 × × 6 × 4 = 6 × 4 = 24 units²
SA = 42 + 70 + 24 = 136 units²
Answer:
-2g - 11
Step-by-step explanation:
Expand the brackets, multiply 2 over 3g and -4. One plus and one minus make a minus.
2(3g-4) - (8g+3) = 6g - 8 - 8g - 3
Evaluate like terms.
6g - 8 - 8g - 3 = -2g - 11
