price is 15¢. Which formula best describes the cost C in
dollars of buying D doughnuts (assuming the D > 12)?

Answer: there are no answer choices but f > 2

Step-by-step explanation:

If the sample variance of hourly wages was 10 then the sample standard deviation of hourly wages C)  $3.16

The formula for calculating the sample standard deviation is the square root of the sample variance.Since the the sample variance of hourly wages was 10 given in the question.

sample standard deviation = square root of (sample variance) = square root of 10 = $3.16.

s = sqrt(10)

s = 3.16

Therefore, the sample standard deviation is $3.16. Option C is the correct answer.

The positive angle between 0 and 2 radians that is coterminal with the angle −143 radians is 1.057 radians, which is equal to 59.8°.

To find the positive angle in radians that is coterminal with −143 radians, we must first convert the negative angle to its equivalent positive angle. The angle −143 radians is equivalent to the angle 2π - 143 radians. We can calculate this by using the formula 2π + x = 2π - |x|, where x is the given angle. In this case, x = −143. Applying this formula, we get 2π + (−143) = 2π - |−143| = 2π - 143. This is the equivalent positive angle of the given negative angle. To find the positive angle that is coterminal with the positive angle we just found, we must subtract it from 2π until we get a value that is between 0 and 2π. To do this, we subtract 2π - 143 from 2π until we get a value that is between 0 and 2π. After subtracting 2π - 143 from 2π multiple times, we get the result 1.057 radians, which is equal to 59.8°. Therefore, the positive angle between 0 and 2 radians that is coterminal with the angle −143 radians is 1.057 radians.

The statement that best describes the total cost of the Screened Loam, Round stone, and Crushed stone is; D: The total cost is greater than $325

We are given the amount of each material required for the Landscaping Project as;

Screened Loam = 3.25 cubic yards

Round stone = 1.5 cubic yards

Crushed stone = 2.5 cubic yards

Likewise we are given the cost of each of these materials per cubic yard as;

Cost of Screened Loam = $26 per cubic yards

Cost of Round stone = $112.5 per cubic yards

Cost of Crushed stone = $37.5 cubic yards

Thus;

Total Cost = (26 * 3.25) + (112.5 * 1.5) + (37.5 * 2.5)

Total Cost = 84.5 + 168.75 + 93.75

Total Cost = $347

The subspace among the given options is W = {p ∈ Ba | p(-3) = 0}.

W = {p ∈ Ba | p(-3) = 0} is a subspace because it satisfies the properties of a subspace.

To determine whether a set is a subspace, we need to verify three conditions: closure under addition, closure under scalar multiplication, and the presence of the zero vector. In the given option, W = {p ∈ Ba | p(-3) = 0} represents the set of polynomials in variable a, such that the polynomial evaluated at -3 is equal to 0.

To prove that W is a subspace, we need to show that for any two polynomials p₁ and p₂ in W, their sum p₁ + p₂ is also in W. Additionally, for any scalar c, the scalar multiple c · p is in W. Moreover, the zero polynomial, which satisfies p(−3) = 0 for all a, belongs to W.

Upon checking, we find that W satisfies all the conditions, and hence, it is indeed a subspace. The polynomials in W are closed under addition and scalar multiplication, and the zero polynomial is present in W. Thus, W meets the requirements of being a subspace.

Answer:

3 hamburger packs

5 hot dog packs

Step-by-step explanation:

Knowing that:

Gary buy ⇒ 8 packages for a total of $28.52

A package of hot dogs costs $2.29 and a package of hamburgers costs $5.69.

Solving:

Let the Hotdogs = HD

Let the Hamburgers = HB

HD + HB = 8

2.29HB + 5.69HB = 28.52

Hotdogs (HD) = 2.29

Hamburgers (HB) = 5.69

Total ( 8) = 28.52

Since we now know that

Hotdogs (HD) = 2.29

Hamburgers (HB) = 5.69

Thus,

2.29x5 = 11.45

5.69 x 3=17.07

17.07 + 11.45 = 28.52

Thus, gray buy

No, they cannot construct a cube from the square pieces of foam board.

A square has four equal sides. When we multiply the length and width of a square to determine its area, we are essentially squaring one of its sides because they are the same.

A=s²

If we already know the area, we can work backward and take the square root to find the side:

√169=√s²

13=s

13 inches is the side length.

The length, breadth, and height of a cube are all equal. These three measurements are multiplied to determine a cube's volume; since they are equal, this essentially equals cubing the side length:

V=s³

The volume is 1728, so we have the following:

1728=s³

We take the cubed root and move backwards:

∛1728=∛s³

12=s

Answer:

x = 15°

Step-by-step explanation:

∠2 and ∠4 are same-side interior angles, meaning they add up to 180

2x + 10 + 4x + 80 = 180

Rearrange (collect like terms)

6x = 180 - 80 - 10

6x = 90

x = 15°

Answer:

Step-by-step explanation:

∠2 = 2x + 10

∠4 = 4x + 80

∠2 and ∠4 are supplementary angles, this mean ∠2 + ∠4 = 180

2x + 10 + 4x + 80 = 180

The ratio of the cooling time of Earth to the cooling time of the exoplanet is 16,777,216.

An exoplanet, also known as an extrasolar planet, is a planet that orbits a star other than the Sun, which is part of our solar system. An exoplanet is one of many planets that might exist in the universe outside of our solar system.

The ratio of the cooling time of Earth to the cooling time of the exoplanet can be determined using Stefan-Boltzmann's Law and Wien's Law.

We first need to use the Stefan-Boltzmann Law in order to calculate the cooling time.

σT⁴ = L/(16πR²)

σ(5780)⁴ = (3.846 × 10²⁶ W)/(16π(6.3781 × 10⁶)² m²)

Ratio of the exoplanet's radius to the Earth's radius:

re/rE = 8.00

Ratio of the exoplanet's mass to the Earth's mass:

me/mE = (re/re)³ = 8³ = 512 (since density is assumed to be the same for both planets)

Ratio of the exoplanet's luminosity to the Earth's luminosity:

Le/LE = (me/mE)(re/rE)² = 512(8)² = 32768

Ratio of the exoplanet's temperature to the Earth's temperature:

Te/TE = (Le/LE)¹∕⁴ = 32768¹∕⁴ = 32.0

The Wien Law can now be used to determine the ratio of the cooling times of the two planets.

(T/wavelength max)E = 2.898 × 10⁻³ m K(5780 K) = 1.68 × 10⁻⁸ m (using Earth as the comparison planet)

(T/wavelength max)e = 2.898 × 10⁻³ m K(Te)(8.00) = wavelength max (using the exoplanet)

Ratio of the wavelengths:

wavelength max,e/wavelength max,E = (Te/TE)(re/rE) = 32.0 × 8.00 = 256

Ratio of the cooling times:

cooling time,e/cooling time,E = (wavelength max,e/wavelength max,E)³ = 256³ = 16,777,216

Hence, the ratio of Earth's cooling time to the exoplanet's cooling time is 16,777,216.

Answer:

Step-by-step explanation:

If two angles are complementary, then their sum is 90°.

So we can build an equation using this information.

The angles are 3x + 23 and 3x + 25, respectively.

\(\bf{3x+23+3x+25=90}\)

Combine the like terms

\(\bf{6x+48=90}\)

Now just solve for x

\(\bf{6x=90-48}\)

\(\bf{6x=42}\)

\(\bf{x=7}\)

Knowing that x = 7, we can plug it into the expressions

3x + 25

3(7) + 25

21 + 25

46

Now the other angle is:

3x + 23

3(1) + 23

21 + 23

44

Hence, the measures of  \(\angle A\) and \(\angle B\) are 44 and 46, respectively.

Answer:

m∠3 = 70°

Step-by-step explanation:

By the properties of a parallelogram,

- Opposite angles of a parallelogram are equal in measure.

- Adjacent angles of a parallelogram are supplementary angles.

m∠2 = m∠4 and m∠1 = m∠3

4x + 30 = 2x + 70

4x - 2x = 70 - 30

2x = 40

x = 20

Therefore, m∠2 = m∠4 = 110°

Since, m∠2 + m∠3 = 180°

110° + m∠3 = 180°

m∠3 = 180° - 110°
