The surface area of the sphere is 108.16π in². So, option b is correct.

<h3>What is the surface area of a sphere?</h3>

The surface area of the sphere is calculated by the formula,

A = 4πr²

In terms of diameter - d;

A = 4π × (d/2)²

  = 4π × d²/4

  = πd² sq. inches

<h3>Calculation:</h3>

The given sphere has a diameter d = 10.4 inches

So, the surface area of the sphere is calculated by

A = πd²

  = π × (10.4)²

  = 108.16 π sq. inches

So, option b is correct.

Hezekiel runs 1000 m at a rateof 3 minutes per km. how long does he take to run 500 m​
lana66690 [7]

Step-by-step explanation:

1 km = 1000 m

(hence the term "kilo" which means 1000).

so. he runs 1000 m at the rate of 3 minutes per km, that means 3 minutes per 1000 m.

now, we can see the solution already with our eyes.

but let's do it formally :

the rate or ratio between time and distance must be the same for the same speed.

so,

3 min / 1000 m = x min / 500 m

500 m × 3 min / 1000 m = x min

1/2 × 3 min = x min

3/2 = 1.5 min = x min

so, it takes him 1.5 minutes (90 seconds) to run 500 m.

Solve a Quadratic EquationUse the following equation to answer the questions:3x2 - 8x + 1 = 314 1 pointWhat is the discriminant?
emmainna [20.7K]

Δ=88

1) Using the Quadratic Equation to Solve

3x²-8x+1=3

3x²-8x+1-3=3-3

3x² -8x -2=0

2)Let's find the discriminant

Δ= (-8)²-4(3)(-2)

Δ=64 -4(3)(-2)

Δ=88

a new car, originally worth $35,795, depreciates at a rate of 17% per year. The value of the car can be represented by the equat
Sergio [31]

We have been given that a new car, originally worth $35,795, depreciates at a rate of 17% per year. The value of the car can be represented by the equation y=35795(0.83)^x, where x represents the number of years since purchase and y represents the value (in dollars) of the car.

To find the value of car of after 5 years, we will substitute x=5 in our given equation as:

y=35795(0.83)^5

y=35795\cdot (0.3939040643)

y=14099.79598

Upon rounding to nearest tenth, we will get:

y\approx 14099.8

Therefore, the car will be worth $14,099.8 after 5 years it is first purchased.

Since $14,099.8 is less than original value of car, therefore, we know hat value of car is depreciating and $14,099.8 is correct answer.

We also know that an exponential decay function is in form y=a(1-r)^x, where,

y = Final value after t years,

a = Initial value,

r = Decay rate in decimal form,

x= Time.

17\%=\frac{17}{100}=0.17

y=35795(1-0.17)^x

y=35795(0.83)^x

△ABC is similar to △LMN by the ​ AA Similarity Postulate ​ . The measure of ∠A is 57º and m∠C=2(m∠M).
Agata [3.3K]
△ABC is similar to △LMN by the ​ AA Similarity Postulate ​. The measure of ∠A is 111º and m∠C=2(m∠M).

Since the Angle of A is 111 degrees.
Another angle, Angle of C is twice the angle of M.

Angle of A = Angle of C
2 (Angle of M) = Angle of C
2 (Angle of M) = 57
<span>Angle of M = 28.5 degrees</span>
