There are 74.227 milliliters of acid in the solution.
Explanation:
- The total amount of liquid is 373 milliliters. This is both the acid and water combined i.e amount of liquid + amount of acid = 373 milliliters
- If 19.9% of this is acid it means 19.9% of the the entire 373 milliliters is acid. So we calculate how much 19.9% of 373 milliliters is.
- 19.9% of 373 milliliters = 0.199 × 373 = 74.227 milliliters. So 74.227 milliliters of the entire solution is acid.
Answer:
area= 144ft^2
Step-by-step explanation:
width = x
length = 4x
perimeter = 2(4x+x)
60/2=5x
30=5x
x=30/5
x=6
width 6 feet
length 4(6)
= 24
area = length * width
=6*24
=144ft^2

Step-by-step explanation:
<u>Step 1: Define</u>
-6 = b8
<u>Step 2: Solve for </u><em><u>b</u></em>
- Rewrite: -6 = 8b
- Divide 8 on both sides: -6/8 = b
- Rewrite: b = -6/8
- [Fraction] Simplify: b = -3/4
<u>Step 3: Check</u>
<em>Plug in b into the original equation to verify it's a solution.</em>
- Substitute in <em>b</em>: -6 = (-3/4)8
- Multiply: -6 = -24/4
- Divide: -6 = -6
Here we see that -6 does indeed equal -6.
∴ b = -3/4 is the solution to the equation.
Answer:
c i think
Step-by-step explanation:
Answer:
9.4 feet to the nearest tenth.
Step-by-step explanation:
This makes a right triangle so we use Pythagoras:
23^2 = 21^2 + d^2 where d is the required distance.
d^2 = 23^2 - 21^2
d^2 = 88
d = √88 = 9.3808
