The expressions that can represent the dimensions of the prim is (x), (3x+1) and (4x-1).
Answer:
Step-by-step explanation:
Let chocolate bar = c and blow pops = b
<u>As per given we have equations below:</u>
- 5c + 8b = 23.25
- 2c + 13b = 21.55
<u>13 times the first equation minus 8 times the second to eliminate b and find c:</u>
- 13(5c + 8b) - 8(2c + 13b) = 13(23.25) - 8(21.55)
- 65c - 16c = 129.85
- 49c = 129.85
- c = 129.85/49
- c = 2.65
Each chocolate bar costs $2.65
Answer:
- b
- f
- e
- c
- h
- d
- g
- a
Step-by-step explanation:
< or > will give you an open dot which means it is not filled in.
≤ or ≥ will give you a closed dot which means it is filled in.
So for example number one:
x > 0 translated is x is greater than zero.
So look on the number line for an open dot on zero going toward the left (the side where the numbers get smaller). The rest are self explanatory.
Answer:
Volume of a cylinder = 653.12 cm³
Step-by-step explanation:
Volume of a cylinder = πr²h
Where,
Height, h = 13 cm
Radius, r = 4 cm
π = 3.14
Volume of a cylinder = πr²h
= 3.14 × (4cm)² × 13 cm
= 3.14 × 16 cm² × 13 cm
= 653.12 cm³
Volume of a cylinder = 653.12 cm³
All you have to do is make the fraction of it which is 4/30. Then simplify to 2/15 which is your answer.
