Answer: 12/30
and 40 percent
Step-by-step explanation:
Well it’s 12 to 30 so just put a fraction bar
and 12 divided by 30 is .4
Answer:
The answers are 12/30 and 10%
Step-by-step explanation:
It's 40% because the ratio of males to total students is 12 to 30, or 12:30, which is equal to 12/30.
The other answer is 10% because the ratio of males to total students is 3 to 30, or 3:30, which is equal to 1/10. Then you would do 100 divided by 10 which would give you 10 so it's 10%.
Hope this helps!

Which statement provides a set of arguments that supports the relationship
between the measures of <2 and <7?
A. Since <2 has the same measure as <8, and <8 has the same measure as
27, then <2 has the same measure as <7.
B. Since <2 has the
same measure as <6, and <6 has the same measure as
<7, then <2 has the same measure as <7.
C. Since <2 is supplementary to <6, and <6 has the same measure as <7,
then <2 is supplementary to <7.
D. Since <2 is supplementary to <8, and <8 is supplementary to <7, then
<2 is supplementary to <7.

Naomi buys an antique dresser for $1200. Each year, it appreciates (increases in value) by 3.5%. Write an equation to determine its value V(n) after n number of years
9514 1404 393
Answer:
V(n) = 1200·1.035^n
Step-by-step explanation:
The value multiplies by 1+3.5% = 1.035 each year. After n years, that growth factor has been applied n times, so the value is ...
V(n) = 1200·1.035^n

Which of the following equations is equivalent to ab − 8 = 3b, when solving for b .
a = 11
b = 8/2a
b = -8/3 - a
b = -8/a - 3
The equivalent equation for the given equation is b=8/(a-3).
What is an equivalent equation?Algebraic equations with equivalent solutions or roots are called equivalent equations. An analogous equation is one that is created by adding or removing the identical quantity or expression from both sides of a given equation. An equation is equivalent if both sides are multiplied or divided by the same non-zero value.
The given equation is ab-8=3b.
Now, transpose 3b to other sides of an equation, we get
ab-3b=8
b(a-3)=8
b=8/(a-3)
Therefore, the equivalent equation for the given equation is b=8/(a-3).

Answer: 0.000021 in scientific notation is
2.1 × 10-5
Step-by-step explanation:
All numbers in scientific notation or standard form are written in the form
m × 10n, where m is a number between 1 and 10 ( 1 ≤ |m| < 10 ) and the exponent n is a positive or negative integer.
To convert 0.000021 into scientific notation, follow these steps:
Move the decimal 5 times to right in the number so that the resulting number, m = 2.1, is greater than or equal to 1 but less than 10
Since we moved the decimal to the right the exponent n is negative
n = -5
Write in the scientific notation form m × 10n
= 2.1 × 10-5
Therefore,
2.1 × 10-5 is the scientific notation form of 0.000021 number and 2.1e-5 is the scientific e-notation form for 0.000021
