Find the approximate radius of a circle with a circumference of 198 centimeters. Use 3.14
for it Round to the nearest hundredth.

A. 63.06
B. 31.53
C. 621.72
D. 310.86

Answers

Answer 1

The radius of the circle is around 31.65 cm. Choice B

The formula C = 2πr , where C is the circle's circumference and r is its radius, yields the circumference of a circle. In this illustration, the circle's circumference is given as 198 cm

C = 2πr

The formula to calculate the radius can be revised as follows:

r = C / (2π)

r = 198 / (2 * 3.14)

To perform the calculation, divide the numbers:

r ≈ 198 / 6.28

r ≈ 31.65

The circle's estimated radius is 31.65 centimetres as a result.

So, rounded to the closest hundredth, the estimated radius of the circle with a circumference of 198 centimetres is 31.65 centimetres.

The closest option to 31.65 in the list of possible answers is B. 31.53. It's crucial to keep in mind that choosing 3.14 as an approximation for involves some mistake and that the precise radius number might change slightly.

When rounded to the next hundredth, the radius is 31.65. This result can be compared to the other solutions to show that:

B. 31.53.

Veronika works as a cook at Toyem Catering, she makes $58,200/year. She pays 18% in taxes and $125/month for health insurance. What is Veronika's net income per month?

a
$4,200
b
$3,852
c
$4,850
d
$2,989

Answers

Veronika's net income per month is $3,852. Option B

How to calculate Veronika's net income per month

The annual  amount of taxes that Veronika pays:

Annual taxes = 0.18 x $58,200 = $10,476

Annual health insurance = $125/month x 12 months = $1,500

we can calculate Veronika's net annual income by subtracting the taxes and health insurance from her annual salary:

Net annual income = $58,200 - $10,476 - $1,500 = $46,224

We can calculate her net income per month by dividing her net annual income by 12:

Net monthly income = $46,224/12 = $3,852

C. There are infinitely many solutions because the variables cancel each other.
D. There is no solution because 9 ≠ -3.

Answers

Answer:

D. There is no solution because 9 ≠ -3.

Step-by-step explanation:

For finding out the statement let's check it ourselves

x + 9 - 4x = - 3x - 3

-3x + 9 = - 3x - 3

9 ≠ - 3

So there is no solution for the equation.

Given this set of data: 132 127 106 140 158 135 129 138 What are the lower outlier limit and the upper outlier limit ? Answers separated by a comma and a space. Ex. 11, 179 * 1 point

Answers

Answer:

(111.5, 155.5)

Step-by-step explanation:

Given the data:

132 127 106 140 158 135 129 138

The Outlier formula :

Lower = Q1 - 1.5(IQR)

Higher = Q3 + 1.5(IQR)

Using a calculator :

Q1 = 128

Median, Q2 = 133.5

Q3 = 139

IQR = Q3 - Q1 = 139 - 128 = 11

Lower = Q1 - 1.5(IQR) = 128 - 1.5(11) = 111.5

Higher = Q3 + 1.5(IQR) = 139 + 1.5(11) = 155.5

(111.5, 155.5)

What is the green dashed line called?

Answers

Answer:

The line (or "axis") of symmetry is the y-axis, also known as the line x = 0. This line is marked green in the picture. The graph is said to be "symmetric about the y-axis", and this line of symmetry is also called the "axis of symmetry" for the parabola.

The equation of the function g(x), after the translation, is given as follows: g(x) = (x + 2)² + 4.

What is a translation?

A translation happens when either a figure or a function are moved horizontally or vertically.

The four translation rules for functions are given as follows:

Left a units: f(x + a).

Right a units: f(x - a).

Up a units: f(x) + a.

Down a units: f(x) - a.

The parent function for this problem is given as follows:

f(x) = x².

For this problem, the parent function was moved:

2 units left, hence g(x) = f(x + 2).

4 units up, hence g(x) = f(x + 2) + 4.

Hence the function g(x) is defined as follows:

g(x) = (x + 2)² + 4.

The time to complete the language arts assignment has a mean of 12 minutes and a standard deviation of 4 minutes. The time to complete the mathematics and the time to complete the language arts homework has a correlation rho = -0.75. The variance of the time to complete the entire homework assignment is

Answers

Answer:

4

Step-by-step explanation:

Given that:

X = time taken to complete mathematics homework

Y= time taken to complete language homework

Standard deviation of X ; SD(X) = 3

Standard deviation of Y ; SD(Y) = 4

rho = - 0.375

rho = Cov(X, Y) / SD(X) * SD(Y)

-0.375 = COV(X, Y) / 3 * 4

COV(X, Y) = 12 * - 0.375

COV(X,Y) = - 4.5

Variance(X, Y) = V(X, Y)

V(X, Y) = V(X) + V(Y) + 2COV(X,Y)

V(X) =SD(X)² = 3² = 9

V(Y) = SD(Y)² = 4² = 16

V(X,Y) = 9 + 16 + 2(-4.5)

V(X, Y) = 16

SD(X, Y) = sqrt(V(X, Y)) = sqrt(16) = 4

Hence, standard deviation to complete entire homework, SD(X, Y) = 4

Answers

Answer:

a. Velocidad = 16 m/s

b. Deceleración = 0.64 m/s²

Step-by-step explanation:

Dados los siguientes datos;

Tiempo = 25 segundos

Distancia = 400 metros.

a. Para encontrar la velocidad;

Velocidad = distancia/tiempo

Velocidad = 400/25

Velocidad = 16 m/s

b. Para encontrar la desaceleración;

Durante una desaceleración, la velocidad inicial es mayor que la velocidad final.

Deceleración = (v - u)/t

Sabemos que la velocidad final es igual a cero (0) porque el automóvil se detiene.

Deceleración = (0-16)/25

Deceleración = 16/25

Deceleración = 0.64 m/s²

Omar is planning to buy some new baseball shoes. He has already saved $22.50

The shoes cost at least 38 dollars.

At least means, greater than or equal to which is represented by the sign

The inequality is given as

22.50 + x ≥ 38

x ≥ 38 - 22.50

x ≥ 15.5
