What is percentage?
A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
here, we have,
to find the number which is 0.4% of 20.
so, we get,
let, the number be x
now, 20* 0.4% = x
or, 20/100= x/0.4
then cross multiply 20/250=x
x = 0.08
which 0.08
Hence, the answer is 0.08

Answer:
Amount in liters is 47.9 liters
Step-by-step explanation:
The Question is incomplete, it does not provide the measurements or options to choose from, but we can estimate the answer
Step one:
Given data
Taryn Bought 12.6gallons of gasoline
1 gallon of gasoline is 3.8 liters
We want to convert from gallons to liters
Step two:
----if 1 gallon has 3.8 liters
then 12.6 gallons will have x liters
cross multiply we have
x= 12.6*3.8
x=47.88 liters
Hence the estimated amount in liters is 47.9 liters

10d + 25q = 1025
Multiply the first equation by 10.
10(d + q = 50) --> 10d + 10q = 500
We combine this with the second equation
10d + 25q = 1025
10d + 10q = 500
--------subtract--------
15q = 525 iff
q = 35
Plug in q = 35 into any of the original equations,
d + q = 50
d + 35 = 50 iff
d = 15
There are 15 dimes, and 35 quarters.

Answer:
Step 1: Remove parentheses using the Distributive Law:
-3 + 5(p+2) = -3 + 5p + 5(2)
Step 2: Collect like terms:
-3 + 5p + 10
The simplified expression is:
5p + 7
Step-by-step explanation:
Step-by-step explanation:
To remove parentheses using the Distributive Law and then collect like terms, follow these steps:
Step 1: Distributive Law
Multiply each term inside the parentheses by the number outside the parentheses:
-3 + 5(p) + 5(2)
Step 2: Simplify
-3 + 5p + 10
Step 3: Collect Like Terms
Combine the constant terms (-3 and 10) and the like terms with 'p' (5p):
5p + 7
So, the simplified expression after removing parentheses and collecting like terms is 5p + 7.
