Answer:
42.9%
Step-by-step explanation:
If 16 are men, this means 12 of the students are women (28 - 16 = 12)
So, 12 out of 28 are women = 12 ÷ 28 = 0.42857... = 42.857...% = 42.9%

Answer:
x = 6 degrees
Step-by-step explanation:
A straight line is 180 degrees and we can make out three angles the form it, this means the three of them add to 180 using the straight angle theorem:
5x + x + 54 + 90 = 180
6x + 144 = 180
6x = 36
x = 6
A snail travels 12 centimeters in 4 minutes. The snail travels the same distance each minute. How many milliliters did the snail travel each minute?
Answer:
the snail travels 30 mm per minute
Step-by-step explanation:
Well 12 cenitmters divided by 4 minutes equals the amount of centimeters the snail travels per minute, which is 3 centimeters (12 / 4 = 3). but be careful cuz we need to convert the 3 cm to mm. 1 cm = 10 mm so 3 cm = 30 mm.
the snail travels 30 mm per minute

-When invested at an annual
interest rate of 7% an account
earned $581.00 of simple
interest in one year. How much
money was originally invested in
account
Answer:
$8300
Step-by-step explanation:
First, you need to know the formula for this type of question.
The formula is I = Prt. These variables are: I = Interest, P = Principle investment, r = Rate, and t = Time.
Your equation will be 581 = P(0.07)(1), since 0.07*1 is 0.07, you'll earn only 7% interest.
So, we broke down the equation to 581 = P(0.07), and you have to isolate P.
Since you have to isolate P, you divide 0.07 from both sides of the equation, which is 581/0.07 = 8300.
So, your principle investment is $8300.
Good luck!
Given f (x) = 5x - 3, find f (-2)
Answer:
f(- 2) = - 7
Step-by-step explanation:
To evaluate f(- 2) substitute x = - 2 into f(x), that is
f(- 2) = 5(- 2) + 3 = - 10 + 3 = - 7

Hey can anyone help with this problem pls and ty !
Step-by-step explanation:
(x + 20)º and (4x - 5)º are supplementary angles, meaning the sum of their angles = 180º.
(x + 20) + (4x - 5) = 180
5x + 20 - 5 = 180
5x + 15 = 180
5x = 165
165/5 = 33
Answer: x = 33

Please help me do it
Step-by-step Explanation:
We are going to solve this problem using integration by parts. We can write the integrand as
[tex]\dfrac{4x}{x^2+4x+3} = \dfrac{4x}{(x+3)(x+1)}[/tex]
[tex]\:\:\:\:\:\:\:\:\:\:\:\:\:= \dfrac{A}{x+3} + \dfrac{B}{x+1}[/tex]
[tex]\:\:\:\:\:\:\:\:\:\:\:\:\:= \dfrac{Ax + A + Bx + 3B}{x^2+4x+3}[/tex]
[tex]\:\:\:\:\:\:\:\:\:\:\:\:\:=\dfrac{(A+B)x + (A+3B)}{x^2+4x+3}[/tex]
Comparing the above term to the left hand side, we can see that
(A + B)x = 4x
A + 3B = 0
Solving for A and B, we find that A = 6 and B = -2 so our integrand becomes
[tex]\dfrac{4x}{x^2+4x+3} = \dfrac{6}{x+3} - \dfrac{2}{x+1}[/tex]
We can now easily integrate this expression as follows:
[tex]\displaystyle \int{\dfrac{4x}{x^2+4x+3}}dx = 6\int{\dfrac{dx}{x+3}} - 2\int{\dfrac{dx}{x+1}}[/tex]
[tex]\:\:\:\:\:\:\:\:\:\:\:\:\:= 6\ln|x+3| - 2\ln|x+1| + C[/tex]

Factor the expression using the common factor −4 .
−12x+2.4y−48
Drag a value or operation/sign to the boxes to correctly factor the linear expression.
Answer:
-4( 3x - 0.6y + 12)
Step-by-step explanation:
The expression - 12x + 2.4y - 48 taken a common factor of - 4 we have
- 4(3x - 2y + 12).
What is a factor of a polynomial?We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.
To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.
The common factor on the other hand is the highest possible value that we can divide each of the given terms.
Given, - 12x + 2.4y - 48.
- 12x + 8y - 48.
Taking - 4 as the common factor we'll have
- 4(3x - 2y + 12).
