Answer:

2352071 ft ^3

Step-by-step explanation:

formula for volume of a sphere is

V= 4/3 * \(\pi\) * r ^3

V = 4/3 * \(\pi\) * 82.5 ^3 = 2352071 ft ^3

Answer:

4/45 = x

Step-by-step explanation:

Strongly suggest that you enclose the fractional coefficients inside parentheses to reduce possible ambiguity:

(3/4)x + 2/5 = 4x - (1/4)x

Consolidate the x terms on the right side and leave the 2/5 on the left:

2/5 = (4 - 1/4 + 3/4)x, or

2/5 = (4 1/2)x   or 2/5 = (9/2)x

Solving for x:  Multiply both sides by (2/9):

(2/9)(2/5) = (2/9)(9/2)x, or:

4/45 = x

A restricted lifestyle is not an advantage of renting.

Option D is the correct answer.

Renting a property has several advantages, such as ease of mobility, fewer responsibilities, and lower initial costs.

We have,

Ease of mobility is an advantage because it is easier for renters to move to a new location since they are not tied down to a specific property.

Fewer responsibilities are another advantage because the landlord is usually responsible for maintaining the property, making repairs, and paying for utilities.

This means that renters do not have to worry about these tasks or expenses.

Lower initial costs are also an advantage because renters do not have to pay for a down payment or closing costs, which can be a significant expense when purchasing a property.

A restricted lifestyle is not an advantage of renting.

This is because renters may be limited in terms of decorating, making changes to the property, or having pets.

Renters may also have to abide by certain rules set by the landlord or property management company.

This can limit their freedom and personalization of the space.

Thus,

A restricted lifestyle is not an advantage of renting.

The truth value of the given statement is false.

The given conditional statement is “If two angles are acute, then they are supplementary.” To determine the truth value of the statement, we have to consider its hypothesis and conclusion.If two angles are acute (hypothesis), then they are supplementary (conclusion).

Let’s take some acute angles and check whether they are supplementary or not. Consider two acute angles of 60° each. As the sum of the measures of two acute angles is less than 180°, they can’t be supplementary. Therefore, the statement is false, and a counterexample has been given.

Hence, the truth value of the conditional statement is false. If two angles are acute, they can't be supplementary.

Proof:Suppose we consider two acute angles A and B. If the two angles are acute, then it means their measures are less than 90°.A + B < 180° (sum of the measures of the angles)< 90° + 90°= 180°

Hence, the sum of the measures of the two acute angles is less than 180°. Therefore, the given statement is false.

Step-by-step explanation:

In this triangle, the product of tan A and tan C is `(BC)^2/(AB)^2`.

The given triangle ABC has angle A measuring 45 degrees, angle B measuring 90 degrees, and angle C measuring 45 degrees , Answer: `(BC)^2/(AB)^2`.

We have to find the product of tan A and tan C.

In triangle ABC, tan A and tan C are equal as the opposite and adjacent sides of angles A and C are the same.

So, we have, tan A = tan C

Therefore, the product of tan A and tan C will be equal to (tan A)^2 or (tan C)^2.

Using the formula of tan: tan A = opposite/adjacent=BC/A Band, tan C = opposite/adjacent=AB/BC.

Thus, tan A = BC/AB tan C = AB/BC Taking the ratio of these two equations, we have: tan A/tan C = BC/AB ÷ AB/BC Tan A * tan C = BC^2/AB^2So, the product of tan A and tan C is equal to `(BC)^2/(AB)^2`.

Answer: `(BC)^2/(AB)^2`.

The correct option is C, It will reduce the margin of error by one-half. This is because the margin of error is inversely proportional to the square root of the sample size.

if Malia quadruples her sample size from 100 to 400, the square root of the sample size increases by a factor of 2, and the margin of error is reduced by a factor of 2.

The square root of a number is a value that, when multiplied by itself, gives the original number. It is denoted by the symbol "√", which is called the radical sign. For example, the square root of 9 is 3 because 3 multiplied by 3 equals 9.

The square root is an important concept in mathematics and has many applications in various fields. It is used in geometry to find the length of the sides of a right triangle, and in physics to calculate the magnitude of a vector. Square roots can be either positive or negative, although when we write √x, we usually mean the positive square root. There are also imaginary square roots, which involve the imaginary unit "i," and are used in complex analysis.

The answer is 20

Step-by-step explanation:

6/8 = 15/y

(6) × y = (8) × (15)

6y = 120

6y/6 = 120/6

y = 20

Thus, The value of y is 20

Answer:

\( \sf \: y = 20\)

Step-by-step explanation:

Given equation,

\( \sf \rightarrow \: \frac{6}{8} = \frac{15}{y} \)

Now the value of y will be,

\( \sf \rightarrow \: \frac{6}{8} = \frac{15}{y} \)

\( \sf \rightarrow \: 6y = 15 \times 8\)

\( \sf \rightarrow \: 6y = 120\)

\( \sf \rightarrow \: y = \frac{120}{6} \)

\( \sf \rightarrow \boxed{ \sf y = 20}\)

Hence, the value of y is 20.

Answer:

Ages are as follows:
Father: 40

Mother: 37

Son: 11

Each twin daughter: 6

Step-by-step explanation:

Interesting puzzle!

Let

F denote the age of the father

M the age of the mother

S the age of the son

D the age of each of the twin daughters

Total of all ages is

F + M + S + 2D = 100  [1]

We also have

F + S = 51   ==>  S = 51- F    [2]

F - M = 3    ==>  M = F - 3    [3]

S - D = 5 ==> D = S -5  [4]

==> D = (51-F) -5  

==> D = 46 - F         [5]

Substitute this in equation [1] to get

We now have everyone's age in terms of the father's age F

Substituting each of equations [2], [3]  and [5] into [1] we get one equation in terms of F

F + (F-3) + (51-F) + 2(46-F) = 100

(F + F - F -2F ) + (-3 + 51 + 92) = 100

-F + 140 = 100

- F = 100 - 140

-F = -40

or

F = 40

From [3]

M = F - 3 = 40 - 3 = 37

From [2]

S = 51 - F = 51 - 40 = 11

From [4]

D = S - 5  = 11 - 5 = 6

Verify:

F + M + S + 2D = 40 + 37 + 11 + 2 x6 = 100

Step-by-step explanation:

a = father age

b = mother age

c = son age

d = daughters age

1. a + b + c + 2d = 100 (don't forget : twin-daughters)

2. a + c = 51

3. a = b + 3

4. d = c - 5

we need to transform the equations 2-4 to express 3 variables by the 4th, and then put that into the first equation and solve for that one variable.

once we have that, we can use again the equations 2-4 to solve for the other variables.

2. tells us that

c = 51 - a

3. tells us that

b = a - 3

4. and 2. tells us that

d = c - 5 = (51 - a) - 5 = 46 - a

with that we get in 1.

a + (a - 3) + (51 - a) + 2(46 - a) = 100

a + a - 3 + 51 - a + 92 - 2a = 100

2a - 3a + 48 + 92 = 100

-a + 140 = 100

-a = -40

a = 40

b = a - 3 = 40 - 3 = 37

c = 51 - a = 51 - 40 = 11

d = c - 5 = 11 - 5 = 6

so, the father is 40 years old

the mother is 37 years old

the son is 11 years old

both of the twin daughters are 6 years old.

Answer: theres no picture

Step-by-step explanation:

the values of a, b, c, and x are:

\(a = 1, b = 0, c = -1.125×10^-6, x = 0.0015\)

The chemical equation for the dissociation of nitrous acid, HNO2, is:

HNO2 + H2O ⇌ H3O+ + NO2-

The acid dissociation constant, Ka, is given as Ka = [H3O+][NO2-]/[HNO2]. Since HNO2 is a weak acid, we can assume that its dissociation is small compared to its initial concentration. Therefore, we can assume that [HNO2] ≈ 0.00250 M and [NO2-] ≈ [H3O+], and substitute these values into the expression for Ka:

\(Ka = [H3O+]^2 / [HNO2]\)

\(4.5×10^-4 = [H3O+]^2 / 0.00250\)

Multiplying both sides by 0.00250, we get:

\(0.00250 × 4.5×10^-4 = [H3O+]^2\)

a = 1, b = 0, and c = -0.00250 × 4.5×10^-4 = -1.125×10^-6. Therefore, the quadratic equation is:

\(x^2 - 1.125×10^-6 = 0\)

Using the quadratic formula, we can solve for x:

\(x = [-b ± sqrt(b^2 - 4ac)] / (2a)\)

Substituting the values of a, b, and c, we get:

\(x = [0 ± sqrt(0 - 4(1)(-1.125×10^-6))] / (2(1))x = [± sqrt(4.5×10^-6)] / 2x = ± 0.0015\)

Since [H3O+] cannot be negative, the only valid solution is:

x = 0.0015
