Answer:
30 mph
Step-by-step explanation:
First we need to find the distance travelled in the first 1h30m.
We can do that multiplying the speed by the time travelled, so we have:
Distance1 = 50 * 1.5 = 75 miles
If the total distance is 120 miles, Michael still needs to travel 120 - 75 = 45 miles.
And if the total time travelled is 3 hours (10 AM - 7 AM), the second part of the travel has a duration of 3h - 1.5h = 1.5h
So if the distance is 45 miles and the time is 1.5 hours, we can find the speed of the second part:
45 = speed * 1.5
speed = 45/1.5 = 30 mph
Answer: B, A, B
<u>Step-by-step explanation:</u>
Let's find the z-score for both companies using the formula: 
Company A: 
Company B: 
The z-score from Company B is closer to 0 than the z-score of Company A so it it more likely that a package of 43 lozenges is produced by Company B
Answer:
Number of whole tiles need = 120,000 tiles
Step-by-step explanation:
Given:
Area of room = 300 m²
Dimension of each tile = 5cm x 5cm
Find:
Number of whole tiles need
Computation:
Dimension of tile in meter = 5 /100 = 0.05 m
Area of each tile = 0.05 x 0.05
Area of each tile = 0.0025 m²
Number of whole tiles need = Area of room / Area of each tile
Number of whole tiles need = 300 / 0.0025
Number of whole tiles need = 120,000 tiles
Total 120,000 tiles need to cover 300 m² room.
Answer: i dunno
Step-by-step explanation: realy
Answer:
A
Step-by-step explanation:
Note that
x² + 12x + 36 is a perfect square → (x + 6)², hence
= 
= (x + 6)
Hence
f(x) × g(x)
= (x + 6)(x³ - 11)
= 
- 11x + 6x³ - 66
= + 6x³ - 11x - 66 → A
