The required solution in scientific notation is 2 × 10¹ .

Scientific notation can be used to indicate values that are either too large or too little to be conveniently written in decimal form (typically would result in a long string of digits).

The given expression is (6.4 × 10³) ÷ (3.2 × 10²)

Simplifying we get :

(6.4 × 10³) ÷ (3.2 × 10²) = 20

This can be written in the scientific notation as : 2 × 10¹

Therefore the required solution is 2 × 10¹

Step-by-step explanation:

14 percent means that for each 100, there are 14 of something.

This is the most common method to calculate 14% of 600. 600 is the Whole, 14 is the Percent, and the Part is what we are calculating. Below is the math and answer to "What is 14% of 600?" using the percent formula.

Percent Formula:

(Whole × Percent)/100 = Part

(600 × 14)/100 = 84

14% of 600 = 84

Answer - The constant proportionality constant of proportionality between the actual dimensions of the pavers and the model is 9. The proportionality constant for the area is 81.

Step-by-step explanation: To solve this problem, let's transform all quantities to the same units (inches)

The actual dimensions of the pavers are:

Then we divide the real dimensions between those of the model:

Width:

Long =

Then, the constant of proportionality between the actual dimensions of the pavers and the model is 9.

Actual length = model length * (9)

The "A" area of a paver is the product of its width multiplied by its length.

So:

(real width) * (real length) = ((9) Model width) * ((9) model length)

(real width) * (real length) =  * (Model width) * (model length)

(real area) = 81 * (Model area)

The proportionality constant for the area is 81.

Answer:

40

Step-by-step explanation:

x + 3x = 300 - 140

4x = 160.

The meaning of vertical intercept in this context can be inferred from the options to mean that the helicopter took off from a height of 50 ft.

In a linear problem or a graph, the vertical intercept, which is also known as the y-intercept, refers to the value of y when the value of x is 0.

Assuming y in this problem refers to the height and x refers to the minutes, the vertical intercept would be the height at 0 minutes.

If the vertical intercept is 50 ft then it means that the helicopter took off from 50 feet because at takeoff, the value of x would be 0 minutes.

The distance between each pair of points (-1,4) and (1,-1) exists √29 units after utilizing the distance formula.

It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.

The distance formula can be given as:

[tex]$\mathrm{d}=\sqrt{\left(\mathrm{x}_2-\mathrm{x}_1\right)^2+\left(\mathrm{y}_2-\mathrm{y}_1\right)^2}[/tex]

It is given that:

The distance between each pair of points (-1,4) and (1,-1)

Two points are (-1,4) and (1,-1)

To estimate the distance between the above two points utilize the distance formula:

[tex]$\mathrm{d}=\sqrt{(1-(-1))^2+(-1-4)^2}$$[/tex]

[tex]$\mathrm{d}=\sqrt{(1+1)^2+(-1-4)^2}$$[/tex]

The arithmetic operation can be described as the operation in which we do the addition of numbers, subtraction, multiplication, and division

d = √[(2)² + (-5)²]

simplifying the above equation, we get

d = √(4 + 25)

d = √29 units

Therefore, the distance between each pair of points (-1,4) and (1,-1) exists √29 units after utilizing the distance formula.

The rate of the water being pumped into the tank is 289,753 cm3/min

d = 4m

∴ r = 2m

h = 6m

Therefore r = h/3

The formula for the volume of the cone is:

V=(1/3)π•r2h

substitute:

V=(1/3)π (h/3)2h

V=(1/27)π h3

Derive both sides with respect to time:

dV/dt = (1/9) π h2• dh/dt

When h= 2 meters = 200 cm when dh/dt = 20

dV/dt = (1/9) π (200)2• (20)

dV/dt = (800,000/9) π ~ 279,252.68

Meaning the volume of water is increasing at a rate of 279,252.68 cm3/min.

However, it's leaking out at a rate of 10,500 cm3/min. Therefore the rate of the water being pumped into the tank is:

279,252.68 + 10,500 = 289,752.68 ~ 289,753 cm3/min

The percentage of puffin eggs that hatch given in decimal form by the quadratic function, f(x) = -0.379•(x - 46)² + 2.62•(x - 46) - 3.61, gives;

a. At 51 °F, 1.5% of the eggs will hatch

b. The temperature at which the maximum percentage of puffin eggs will hatch is approximately 49.5 °F

The maximum percentage of eggs that hatch is approximately 91.8 %

A quadratic function is a polynomial of the second degree (degree 2) such that the highest power of the variables in a quadratic function is 2

The quadratic function is presented as follows;

f(x) = -0.379•(x - 46)² + 2.62•(x - 46) - 3.61

Where;

f(x) = The percentage of the eggs that hatch

x = The mean sea surface temperature of the area in degrees Fahrenheit

a. The percentage of the eggs that will hatch at 51° is therefore;

f(51) = -0.379•(51 - 46)² + 2.62•(51 - 46) - 3.61 = 0.015

The percentage of the eggs that hatch at 51° d is f(51) = 0.015 × 100% = 1.5%

b. The temperature for which the percentage of hatched puffin eggs is a maximum, is given by the maximum value of the quadratic function as follows;

At the maximum value of the quadratic function, f(x) = a•x² + b•x + c, we have;

x = -b/(2•a)

Therefore, where we have;

f(x) = -0.379•(x - 46)² + 2.62•(x - 46) - 3.61

At the maximum value;

x - 46 = -2.62/(2×(-0.379)) = 1310/379

Which gives;

Second part;

The percentage of eggs that hatch at the temperature that gives the maximum percentage of eggs is the maximum percentage of eggs, which is found as follows;

f(46 + 1310/379) = -0.379•(1310/379)² + 2.62•(1310/379) - 3.61 ≈ 0.9179683

Answer:

Weight on Mars:  1,475.32 kg

Step-by-step explanation:

The formula is Weight on Mars= (Weight on Earth/9.81m/s2) * 3.711m/s2.

If a space rover has a mass of 3900 kg on Earth, the mass on Mars when it lands will be 3900kg.

Mass is a dimensionless quantity representing the amount of matter in a particle or object. The standard unit of mass in the International System (SI) is the kilogram.

Given,

The mass of a space rover is 3900 kg.

We need to check what is its mass in Mars.

The mass of space rover  in Mars will also be same 3900 kg because the mars is same quantity it wont change according to place or time, it remains constant. Where as weight would be changed.

The mass of the object is always constant, anywhere it is on the Earth or Moon or any other planet.

Hence, If a space rover has a mass of 3900 kg on Earth, the mass on Mars when it lands will be 3900kg.

Therefore:

⇒ 8x + 11 = 5x + 68

⇒ 8x + 11 - 5x = 5x + 68 - 5x

⇒ 3x + 11 = 68

⇒ 3x + 11 - 11 = 68 - 11

⇒ 3x = 57

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

In mathematics, a line's slope, also known as its gradient, is numerical representation of  line's steepness and direction. The letter m is the frequently used to represent slope; the reason for this usage is unclear, although it can be found in O'Brien's (1844) and Todhunter's (1888) formulations of the equation for the straight line as "[tex]y = mx + b[/tex]" and "[tex]y = mx + c[/tex]," respectively.

The ratio of "vertical change" to "horizontal change" between the (any) two unique points on a line is used to compute slope. The ratio can also be written as a quotient ("rise over run"), which produces the same number for every two distinct points on the same line. A declining line has a negative "rise." The line might be useful, as determined by a road surveyor, or it might appear in a diagram that represents a road or a roof as a description or design.
