Answer:
No
Step-by-step explanation:
Ratio of areas = (Ratio of diameters)²
Ratio of areas = 2² = 4
6 x 7 = 42
And the missing number is 8, because 7 x 8 = 56.
Answer:
- the pressure will decrease
(volume is doubled ,the pressure reduced by half).
Step-by-step explanation:
P_1 V_1=P_2 V_2
This equation shows that, as volume increases, the pressure of the gas decreases in proportion.
Similarly, as volume decreases, the pressure of the gas increases.
Answer:
240 sodas, 160 water, 100 juice
Step-by-step explanation:
multiply everything by 10
Answer:
The student is correct.
Step-by-step explanation:
Given that 5x² = 20:
It is true that the value of x = 2 because 2² = 4, and when you multiply 4 with 5, you'll get a product of 20:
5x² = 20
5(2)² = 20
5(4) = 20
20 = 20
Therefore, the student is correct that x = 2.
