What is the value of n in the equation (2n + 4) + 6 = -9 + 4(2n
+
1)?
(Edulastic)
Answer:
5/2
Step-by-step explanation:
(2n+4)+6=-9+4(2n+1)
2n+4+6=-9+8n+4
2n+10=-9+8n+4
2n-8n=-9+4-10
-6n=-5-10
-6n=-15
6n=15
n=15/6
simplify
n=5/2
HELP ILL GIVE BRAINIEST THIS MY LAST QUESTION!
Jim and Regina can complete one job in 4 hours when working together. When working alone, Jim works twice as quickly as Regina.
• How long will it take each of them to do the job when working alone? Show all work supporting your answer.
• If Regina works as quickly as Jim, how long will it take both of them to do the job working together? Show all work supporting your answer.
Answer:
Jim = 6 hoursRegina = 12 hoursTogether at same rate = 3 hoursStep-by-step explanation:
Let Jim's speed is J and Regina's speed is R and the work is WWe have:
(J + R)*4 = WJ = 2RSubstitute J with 2R:
(2R + R)*4 = W12R = WRegina needs 12 hours to complete work
and
Substitute R with J/2:
(J + J/2)*4 = W 6J = WJim needs 6 hours to complete same work
If Regina works as quickly as Jim:
J + R = 2JThen
Jim can complete 1/6 of work in one hour, they both can complete twice work:
1/6*2 = 1/3Time to complete work:
1: 1/3 = 3 hoursAnswer:

Find the equation of the curve that passes through the point (x, y) = (0, 0) and has an arc length on the interval x is between 0 and pi over 4 inclusive given by the integral the integral from 0 to pi over 4 of the square root of the quantity 1 plus the cosine squared x, dx . (5 points)
Answer:
[tex]\displaystyle y=\sin(x),\text{ where } 0\leq x\leq\pi/4[/tex]
Step-by-step explanation:
The curve passes through the point (x, y) = (0, 0) and has an arc length on the interval [0, π/4] given by the integral:
[tex]\displaystyle \int_{0}^{\pi/4}\sqrt{1+\cos^2(x)}\, dx[/tex]
And we want to find the equation of the curve.
Recall that arc length is given by:
[tex]\displaystyle L=\int_a^b\sqrt{1+\Big(\frac{dy}{dx}\Big)^2}\, dx[/tex]
Rewrite our original integral:
[tex]\displaystyle \int_{0}^{\pi/4}\sqrt{1+(\cos(x))^2}\, dx[/tex]
So:
[tex]\displaystyle \frac{dy}{dx}=\cos(x)[/tex]
It follows that:
[tex]\displaystyle y=\sin(x)+C[/tex]
Using the initial condition:
[tex]0=\sin(0)+C\Rightarrow 0=0+C\Rightarrow C=0[/tex]
The equation for our curve is:
[tex]\displaystyle y=\sin(x),\text{ where } 0\leq x\leq\pi/4[/tex]

What is the first step Anika made from the original equation.
Answer:
She factored out a 4 from the equation.
Step-by-step explanation:
So our original equation is 12x + 4 = 20x - 12
Anika's first steep of her equation is 3x + 1 = 5x - 3
We know that the terms were not moved around, so the first step was likely multiplication or division.
We also see that a 4 has been factored out of the entire equation, like this:
12x + 4 = 20x - 12
4(3x + 4) = 4(5x - 3)
And these 4's cancel each other out.
So, I conclude that Anika's first step was dividing the entire equation by 4 or factoring out a 4 from the equation.

Answer:
FD = 26Step-by-step explanation:
CD = ED --- (secant property)
so, ==>>
13x - 16 = 4x + 11
13x - 4x = 11 + 16
9x = 27
x = 27÷9
x = 3
side ED = 4x + 11 = 4×3 + 11
side ED = 23
side FE = 12
ΔFED = 90° ...... (tangent secant property)
so.........
FE² + ED² = FD² ......... ( by pythagoras theorm)
12² + 23² = FD²
144 + 529 = FD²
673 = FD²
√673 = FD
26 = FD

What is unitary method?Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit
What is the current marked value of US dollar to Canadian dollar?1 United States Dollar = 1.28 Canadian Dollar
According to the question
Chevy Volt costs in the United States = $29,600
As, per current marked value
1 United States Dollar = 1.28 Canadian Dollar
Cost in Canada = 29,600 * 1.28 Canadian Dollar
= 37,888 Canadian Dollar
Hence, the Chevy Volt costs in Canada is 37,888 Canadian Dollar

winston works 40 hours a week as a pharmacist. if he made 75,400 last year, how much was he paid per hour?
Answer:
If I'm calculating correctly, it might be $36.15. Or, if you're rounding, $36.2.
Step-by-step explanation:
There are about 52.14 weeks in a year. If you multiply 40 by 52.14 you get 2085.6. Then you divide 75,400 by 2085.6 and that's how I got my answer. If I'm wrong, someone feel free to correct me.

The measure of one interior angle of a parallelogram is 5 times the measure
of another angle. What's the measurement of the larger interior angle?
Answer:
Step-by-step explanation:
The sum of these adjacent angles must sum to 180 degrees (also the sum of all angles must be 360)
a+5a=180
6a=180
a=30
The larger angle is 5a so the larger angle is
5(30)=150 degrees.

Step-by-step explanation:
Given:
ABCD is PARALLELOGRAM
∠CDA = 81°
Find:
∠DAB
Computation:
ABCD is PARALLELOGRAM
So,
∠CDA + ∠DAB = 180°
81° + ∠DAB = 180°
∠DAB = 99°

The area of a
circular fountain is
225πft2. What is the
diameter of the
fountain?
Using the formula for area of a circle: area = pi x r^2
You now have:
225pi ft^2 = pi x r^2
Divide both sides by pi:
225 = r^2
Take the square root of both sides:
r = 15
The radius is 15 feet.
The diameter is the radius x 2:
Diameter = 15 x 2 = 30 feet.
Answer: 30 feet.
