Answer:
4 gallons of water.
Step-by-step explanation:
1. There is 1 gallon of 10% solution
2. There is 2% saline in water
3. The equation is 10% of 1 gallon = 2% of solution of x gallons of water + saline
0.1 = 0.02(x + 1)
Subtracting 0.02 from both sides, we get
0.1 -0.02= 0.02x +0.02 -0.02
0.08 = 0.02x
Dividing both sides by 0.02, we get
0.08/0.02 = 0.02x/0.02
x = 4.
4. The answer is 4 gallons of water.
Hope you will understand the concept.
Thank you.
Answer:
100%
Step-by-step explanation:
When the dimensions double, the perimeter doubles.
The percent change can be found from ...
percent change = ((new value)/(old value) -1) × 100%
Filling in your values, you have ...
percent change = ((2×(old perimeter))/(old perimeter) -1) × 100%
= (2 - 1) × 100%
= 100%
The perimeter increases by 100% from the first garden to the second.
Answer:
-4/3
Step-by-step explanation:
2^(8x-8)=4^7x
2^8x-8=4^7x
2^8x-8=4^2×7x
8x-8=2×7x
8x-8=14x
-8=14x-8x
-8=6x
-8/6=x
-4/3=x
x=-4/3
Answer:
the graph of the function is non-linear
the table can be represented by the equation y=4x+4
Step-by-step explanation:
non linear because 1+7=8 and then 10+2 = 12 so they have different numbers to add each time
represented by the equation because the x numbers (1,2,3,4,) all multiplied by 4 and added by 4 gives you y
any more help just ask :)
Answer:
4/7
Step-by-step explanation:
Number of Blue vans = 4
Number of white vans = 3
Total number of vans = Number of Blue vans + Number of white vans
= 4 + 3
= 7 vans
Number of blue vans : Number of white vans = 4 : 3
Fraction of vans that are blue = Number of Blue vans / Total number of vans
= 4 / 7
Fraction of vans that are blue = 4/7
