The value of the given equation 3 2/3x = 2 2/5 is 36/55.

A mixed number is one that combines a whole number and a legal fraction. A number that contains both an integer (whole number) and a correct fraction is known as a mixed number or mixed fraction.

Pretzels, peanuts, Cheerios, and of course, rice and corn Chex are all included in this mix, which is why it is called a mix. Mixed numbers are those that contain both an integer and a fraction.

A mixed fraction is a fraction that is represented by both its quotient and remainder. For instance, 2 1/3 is a mixed fraction, where 2 is the quotient and 1 is the remainder. Therefore, a mixed fraction is a combination of a whole number and a proper fraction.

3 2/3x= 2 2/5

11/3 x=12/5

55x=36

x=36/55

Therefore, the value of the given equation 3 2/3x = 2 2/5 is 36/55.

According to the Pythagorean theorem, The Answer is Yes the third side is greater than 1 foot.

A right triangle is one that has an interior angle of 90 degrees. The hypotenuse, which is also the side of the right triangle that faces the right angle, is its longest side. The height and base make up the two arms of the right angle.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

The factors of the given expression 54a⁴ +16ab³ are (C) 2a(27a³+8b³).

Writing a number or other quantitative item as the result of numerous factors—typically smaller or easier objects of the same kind—is known as factorization or factoring in math.

For instance, the equation x2 - 4 and the integer 15 can both be multiplied by the number 3 5.

So, we got the expression:

54a⁴ +16ab³

Now, factorize as follows:

54a⁴ +16ab³

Both 54 and 16 are multiples of 2 and have variables as common:

Clark will have $5820.80 in his account when he turns 22.

With an example, what is compound interest?

The interest you earn on interest is known as compound interest. Simple math may be used to demonstrate this: if you have $100 and it generates 5% interest annually, you will have $105 at the end of the first year. You will wind up with $110.25 at the conclusion of the second year.

Clark reportedly placed $5000 at a constant 3.8% interest rate when he was 18 years old.

Using the compound interest calculation, we can calculate how much Clark will make when he turns 22.

[tex]A=P . e^{rT}[/tex]

A= Amount after T years.

P= Principal amount.

e= Mathematical constant e.

r= Interest rate (in decimal form).

T=  Time in years.

Let's decimalize the interest rate we've been given.

3.8 percent = 3.8/100 = 0.038

When we enter our provided values into the formula above, we will obtain,

[tex]A=5000 * e^{0.038(22-18)} \\A=5000*e^{0.038(4)}\\A=5000*e^{0.152}\\A=5000*1.1641\\A=5820.80[/tex]

The distance from the lighthouse is 64 ft and the distance from Maya to the lighthouse is 56 ft

From the question, we have the following parameters that can be used in our computation:

Height of lighthouse = 48 ft

Height of Maya = 6 ft

Using the above parameters and the attached figure, we have the following equivalent ratio

48 : x = 6 : 8

Multiply the second ratio by 8

So, we have

48 : x = 48 : 64

This means that

x = 64

From the figure, we have

y + 8 = x

Recall that

x = 64

So, we have

y + 8 = 64

3y = -4x + 7

y = -4/3x + 7/3

The slope of the given line is -4/3 so the slope of a line perpendicular to it is 3/4 (negative reciprocal).

y = 3/4x + b

Substitute x = 4 and y = 2:

2 = 3/4(4) + b

2 = 3 + b

b = -1

[tex]\lim\limits_{n \to \infty} \sum\limits_{i=1}^n x_i\cdot ln \left(1 + x_i^2 \right) \Delta x, [2, 6][/tex]

The Riemann sum can be converted into a definite integral, using the equation, [tex]\displaystyle{\lim\limits_{n \to \infty} \sum\limits_{i=1}^n f(x_i)\Delta x = \int\limits^b_a {f(x)} \, dx }[/tex]as follows;

The measurements of the figures that should be equal in order for the ratio of volumes between the volumes of the cone, sphere, and cylinder of 1:2:3 to be true is; The radius and the height

A ratio is a comparison between the magnitudes or measurements of items, expressing the number of times one item in the ratio is contained within another item in the ratio.

The formula for the volume of a cone, [tex]V_p[/tex] is, [tex]V_p[/tex] = (1/3)·π·r₁²·h₁

The formula for the volume of a sphere, [tex]V_s[/tex], is [tex]V_s[/tex] = (4/3)·π·r₂³

The formula for the volume of a cylinder, [tex]V_c[/tex], is [tex]V_c[/tex] = π·r₃²·h₃

The ratio of the volumes in the question is 1:2:3

Therefore; The volume of the sphere is twice the volume of the cone, and the volume of the cylinder is three times the volume of the cone, which indicates;

(4/3)·π·r₂³ = 2 × (1/3)·π·r₁²·h₁...(1)

π·r₃²·h₃ = 3 × (1/3)·π·r₁²·h₁...(2)

Equation (1) indicates that we have;

(4/3)·π·r₂³ = 2 × (1/3)·π·r₁²·h₁

Where, h₁ = 2·r₂, we get;

(4/3)·π·r₂³ = 2 × (1/3)·π·r₁²·(2·r₂) = (4/3)·π·r₁²·r₂

Therefore; r₁ = r₂, and the diameter of the sphere is equal to the height of the cone

The radius of the cone is equal to the radius of the sphere

Equation (2) indicates;

π·r₃²·h₃ = 3 × (1/3)·π·r₁²·h₁ = π·r₁²·h₁

Therefore;

r₃²·h₃ = r₁²·h₁

r₃ = r₁

h₃ = h₁
