Answer:
about 9.4 units
Step-by-step explanation:
Distance formula:
√(x1 - x2)² + (y2 - y1)²
Coordinates:
A (4, 2)
B (9, 10)
Let's make 9 = x1
Let's make 4 = x2
Let's make 10 = y1
Let's make 2 = y2
Substitute into the distance formula:
√(x1 - x2)² + (y2 - y1)²
√(9 - 4)² + (2 - 10)²
Solve:
√(9 - 4)² + (2 - 10)²
√(5)² + (-8)²
√25 + 64
√89
≈ 9.4
Therefore, the length of AB is approximately 9.4 units.
Answer:
I believe it is 9
Step-by-step explanation:
alls I did was add the adults to the students then I divide 375 by 44 I got a weird decimal so I rounded it up to 9
Answer:
cube root of volume
Step-by-step explanation:
Answer:
3.98
Step-by-step explanation:
From the above question,
Cost is directly proportional to the Number of pounds
Hence:
C ∝ N
= C = kN
Where k = Proportionality constant
We are told:
Last week, she bought two pounds and paid $7.96,
Hence:
7.96 = 2k
k = 7.96/2
k = 3.98
This week she bought only one half pound and paid $1.99,
1.99 = k × 1/2
k = 1.99/ 1/2
k = 3.98
Hence, the constant rate of proportionality is 3.98
