First, add the 0.7 over
0.3=0.5f-0.7
1=0.5f
Then divide by 0.5 on both sides
f=2
Step 1: Divide $5.25 by 5
=1.05
Step 2: Multiply 1.05 by 3
= 3.15
Step 3: You're done!
Answer:
9 pounds per square inch
Step-by-step explanation:
Let V = the gas' volume and P = its pressure. The volume of a gas in a container varies inversely with the pressure on the gas:
V = k/P
where k is a constant. To find the value of k, plug in the one known point, V = 390 cubic inches when P = 7 pounds per square inch and solve for k:
V = k/p
390 = k/7
390*7 = k
2730 = k
The full equation, then, is:
V = 2730/P
To find the volume when P = 9 pounds per square inch:
V = 2730/9 = _____ cubic inches
Answer:
Ratio of their perimeters is 6:7
Step-by-step explanation:
Ratio of Area of Hexagon = 36: 49
We need to find ratio of their perimeters
The formula used to find Area of Hexagon is: 
So, we can write:

So, we get a₁=6 and a₂=7
Now, finding ratio of perimeters:
The formula used is:

Ratio will be:

So, Ratio of their perimeters is 6:7
The one-digit integers that satisfy the inequality k>0 are 1, 2, 3, 4, 5, 6, 7, 8, and 9.
<h3>What is a number line?</h3>
A number is a line that is made up of positive and negative numbers with the distance between the preceding and succeeding unit to be 1.
- The negative values on the number line are -1, -2, -3...-9 while the value greater than zero are 1, 2, 3, 4,...9
- Hence the one-digit integers that satisfy the inequality k>0 are 1, 2, 3, 4, 5, 6, 7, 8, and 9.
