Answer:
He must study for at least 7.5 hours each week
Step-by-step explanation:
Here, we want to know the number of hours that Mr Smith must study each week
From the question, we are told that he must study a minimum of 60 hours total over the course of the 8 weeks
The number of hours he must study each week will be 60/8 = 7.5 minimum number of hours each week
The answer is d. 384 m3.
The volume (V) of the box is:
V = l × w × h
l - the length of the box
w - the width of the box
h - the height of the box
If V1 = 48 m³ = l × w × h and all its dimensions are doubled to create box B, then:
V2 = 2l × 2w × 2h = 2 × 2 × 2 × l × w × h = 8 x l × w × h
We know that l × w × h is 48 m³, so:
V2 = 8 x l × w × h = 8 × 48 = 384 m³
<u>Find the diagonal length:</u>
a² + b² = c²
c² = 4² + 6²
c² = 52
c = √52
-
<u>Find the length AB:</u>
a² + b² = c²
c² = (√52)² + 1²
c² = 52 + 1
c² = 53
c = √53
-
Answer: Length AB = √53
<span>First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. If your answer is a negative number then this is a percentage decrease.</span>
