The inequality would be in the direction of the arrow
The arrow is <—— so the inequality is <
The circle is colored so -3 in including making it less than or equal
x<-3
_
Or B
The possible values of x could be -5 and -1 ithink idk
Answer:
a. 754cm³ (3 s.f.)
b. 415cm² (3 s.f.)
Step-by-step explanation:
Formulas (for easier reference):
Volume of cone: 
r²
Volume of hemisphere: 
r³
Surface area of cone without base: rl
Surface area of hemisphere without base: 2r²
We can just apply the formulas for the question:
Volume of toy = ( × 6² × 
) + ( × 6³)
= 96 + 144
= 240
= 754cm³ (3 s.f.)
Surface area of toy = ( × 6 × 10) + (2 × × 6²)
= 60 + 72
= 132
= 415cm² (3 s.f.)
53 races are needed to finish.
<h3><u>Determination of quantities</u></h3>
Given that 271 sprinters enter a race, and the track has 7 lane so only 7 can compete at a time, and at the end 6 non winners are eliminated and the winners race in a later race, to determine how many races are needed to finish the following calculation must be performed:
- 271 / 7 = 38.71 (39)
- 39 / 7 = 5.57 (6)
- 45 / 7 = 6.42 (7)
- 7 / 7 = 1
- 39 + 6 + 7 + 1 = X
- 53 = X
Therefore, 53 races are needed to finish.
