Answer:
Solution: Since, the prime factors of 308 are 2, 7, 11. Therefore, the product of prime factors = 2 × 7 × 11 = 154.
Step-by-step explanation:
13. Is 18
15. Is 86
17 is 5
19 is 15
21 is 24
23 is 29
Answer:
B
Step-by-step explanation:
Since p and v vary inversely then the equation relating them is
p = 
← k is the constant of variation
to find k use the condition p = 8 when v = 40
k = pv = 8 × 40 = 320
⇒ p(v) = 
→ B
Answer: $5
Step-by-step explanation: This can be represented by the equation
40 + 12T = 25 + 15T
We just solve for T.
Subtract 12T from both sides
40 = 25 + 3T Subtract 25
15 = 3T Divide by 3
5 = T
Answer:
5190 g
Step-by-step explanation:
Calculate the volume:
28.0 cm × 4.90 cm × 3.60 cm = 493.92 cm³
Density is mass divided by volume:
D = M / V
Solving for mass:
M = D V
Substituting values:
M = (10.50 g/cm³) (493.92 cm³)
M = 5186.16 g
Rounding to three significant figures, the mass is 5190 g.
