I am thinking of two positive numbers in the ratio $5:3$. The difference between the two numbers is $90$. What is the sum of the two numbers?.
The sum of the two numbers is $ 360
Let the bigger number be x
Let the smaller number be y
From the question given above, we were told that two numbers exist in ratio $ 5 : $ 3
Thus,
x : y = 5 : 3
x/y = 5/3
Cross multiply
x = 5y/3 ............ (1)
Also, we were told from the question that difference between the two numbers is $ 90 i.e
x – y = 90 ........... (2)
Substitute the value of x in equation (1) into equation (2). We have:
x = 5y/3 ............ (1)
x – y = 90 ........... (2)
5y/3 – y = 90
Multiply through by 3
5y – 3y = 270
2y = 270
Divide both side by 2
y = 270 / 2
y = $ 135
Substitute the value of y into equation 1 to obtain the value of x.
x = 5y/3 ............ (1)
y = $ 135
x = (5 × 135)/3
x = 675 / 3
x = $ 225
Finally, we shall determine the sum of the two numbers.
x = $ 225y = $ 135Sum =?Sum = x + y
Sum = 225 + 135
Sum = $ 360
Thus, the sum of the two numbers is $ 360

A student is bouncing on a trampoline. At her highest point, her feet are 95 cm above the trampoline. When she lands, the trampoline sags 25 cm before propelling her back up.
The time she spent in contact with the trampoline is 0.1619 seconds.
The objective of this question is to determine for how long she is in contact with the trampoline?
The conservational force is exerted on the trampoline is equivalent to the sum of the potential energy at the highest point and the elastic energy at the lowest point.
∴
From the given information;

Which of the following is most clearly an example of a theme.
Would sound waves travel slower through air at the north pole or at the equator?.
yes they would travel slower at the north pole than the equator because the air is more dense and is harder to pass through
Yes, sound waves would travel slower at the North Pole than at the equator because the air is denser and is harder to pass through.
What are equators?The Equator is the midline of the earth. A vibration results in a sound. We refer to these motions as "sound waves." Sound waves require a specific medium to travel through. The three different types of media are solid, liquid, and gas.
Keep in mind that since a "solid medium" is denser than the other two, sound waves move through it more quickly. Because water is more densely packed with particles than gas is, sound waves travel faster in liquid than in gas (such as air).
Therefore, yes, because the air is heavier and more difficult to get through at the North Pole than it is at the Equator, sound waves would move more slowly there.

Sunlight changes the distribution of traits in a population because the environment can factor into the distribution of traits.
What is the significance of Sunlight?Sunlight emits light and heat, or solar energy, which allows life to exist on Earth. Sunlight is required for plant growth. Plants are required by animals, including humans, for food and the oxygen they produce.
Earth would freeze if the sun did not provide heat. The sun is necessary for human health and well-being. The health benefits of sunlight include vitamin D production, bone health support, blood pressure reduction, disease prevention, and mental health promotion.

Sea level is currently rising at 5 mm/yr, and scientists predict that global warming could cause a rise in sea level of 7 m if left unabated. How long will it take the sea to rise 7 m at the current rate?.
Answer:
1400 years
Explanation:
Let us convert everything to the same units first. For simplicity, I will convert everything to millimeters.
7 m = 7 m x (1000 mm / 1 m) = 7000 mm
Since the rate is 5, we can use this equation:
rate*time=length
5*years=7000
solve
years=1400
F(x, y) = e−x + y2, e−y + x2 , c consists of the arc of the curve y = cos(x) from − ???? 2 , 0 to ???? 2 , 0 and the line segment from ???? 2 , 0 to − ???? 2 , 0.
Given that y = cos(x) makes up part of the boundary of C, I suspect you mean the given points to be (-π/2, 0) and (π/2, 0).
I also assume the given vector field is
[tex]\vec F(x,y) = \left\langle e^{-x} + y^2, e^{-y} + x^2 \right\rangle[/tex]
Since [tex]\vec F[/tex] has no singularities on C or in its interior, Green's theorem applies:
[tex]\displaystyle \int_C \vec F(x,y) \cdot d\vec r = \iiint_D \frac{\partial(e^{-y}+x^2)}{\partial x} - \frac{\partial(e^{-x}+y^2)}{\partial y} \, dA = 2 \iiint_D (x + y) \, dA[/tex]
where D is the interior of C, the region
[tex]D = \left\{ (x, y) : -\dfrac\pi2 \le x \le \dfrac\pi2 \text{ and } 0 \le y \le \cos(x) \right\}[/tex]
The integral then reduces to
[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \int_0^{\cos(x)} (x + y) \, dy \, dx[/tex]
[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \left( x\cos(x) + \frac12 \cos^2(x) \right) \, dx[/tex]
[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \left( x\cos(x) + \frac{1 + \cos(2x)}4 \right) \, dx[/tex]
[tex]\displaystyle 2 \iint_D (x + y) \, dA = \frac12 \int_{-\frac\pi2}^{\frac\pi2} \left( 4x\cos(x) + 1 + \cos(2x) \right) \, dx[/tex]
Since 4x cos(x) is an odd function over the symmetric interval [-π/2, π/2], its contribution to the integral is 0, and the remaining integral is trivial.
[tex]\displaystyle 2 \iint_D (x + y) \, dA = \frac12 \int_{-\frac\pi2}^{\frac\pi2} \left( 1 + \cos(2x) \right) \, dx = \boxed{\frac\pi2} [/tex]

A 1. 5-kilogram lab cart is accelerated uniformly from rest to a speed of 2. 0 meters per second in 0. 50 second. What is the magnitude of the force producing this acceleration?.
The magnitude of the force producing this acceleration is found to be 3.0 N.
What is Force?Force may be defined as the process of pushing and pulling an object with an appropriate mass in order to cause it to change its velocity with respect to time.
Force is a vector quantity as it has both magnitude and direction. Force is an external agent which is generally capable of changing a body's state of rest or motion with respect to time.
According to the question,
The total mass of an object = 1.5 kg.
The speed of an object = 2.0 m/sec.
So, the formula for calculating the magnitude of the force is as follows:
Force = Mass × Acceleration.= 1.5 kg × 2.0 m/sec = 3.0 N.
Therefore, the magnitude of the force producing this acceleration is found to be 3.0 N.
