If the radius of a circle is 44 cm, then what is the diameter?
no guessing!!

Answer:

15 units²

Step-by-step explanation:

Hi there!

\(A=\displaystyle\frac{1}{2} bh\) where b is the base and h is the height

Plug in the base (7.5) and height (4):

\(A=\displaystyle\frac{1}{2} (7.5)(4)\\\\A=\displaystyle\frac{1}{2} (30)\\\\A=15\)

Therefore, the area of the triangle is 15 units².

Answer: 706,000

Step-by-step explanation:

A pair of corresponding angles, alternate interior angles, and alternate exterior angles include the following:

Corresponding angles: ∠1 ≅ ∠5.

Alternate interior angles: ∠4 ≅ ∠6.

Alternate exterior angles: ∠2 ≅ ∠8

In Mathematics, corresponding angles can be defined as a postulate (theorem) which states that corresponding angles are always congruent when the transversal intersects two (2) parallel lines:

∠1 ≅ ∠5

By applying the alternate interior angles theorem to parallel lines m and n, we have the following congruent angles:

∠4 ≅ ∠6

By applying the alternate exterior angles theorem to parallel lines m and n, we have the following congruent angles:

∠2 ≅ ∠8

Step-by-step explanation:

When x = -2 and y = 5 on both equations, the equations become true.

Answer:

  1. B 15

  2. C Hexagon

Step-by-step explanation:

Euler's formula tells you the relation between numbers of faces, vertices, and edges of a polyhedron is ...

  F +V = E +2

Solving for the number of faces, we have ...

  F = E +2 -V

For the given numbers, the missing number is ...

  F = 26 +2 -13 = 15

  Faces: 15

__

The cross section (shaded figure) is described by the number of edges it has. You can count them. There are three pairs of parallel edges, for a total of 6 edges. That makes the figure a hexagon.

The drug has a half-life of 5 hours

Half-life is the time required for a quantity to reduce to half of its initial value. The term is commonly used in nuclear physics to describe how quickly unstable atoms undergo radioactive decay or how long stable atoms survive. The term is also used more generally to characterize any type of exponential decay.

The formula is given as;

T1/2 = ln2 / λ

Where;

But λ = 15% = 0.15/hr

t1/2 = ln2 / 0.15

T1/2 = 0.693/0.15

T1/2 = 4.62 = 5 hours.

Answer:

52

Explanation:

39 ÷ 3 = 13 4 × 13 = 52

Answer:

((1+2)x3) + (4x5) = 29

Step-by-step explanation:

Since 4x5 = 20 and 3x3 = 9, and 9 + 20 = 29, we put parenthesis around 1+2,

we get,

((1+2)x3) + (4x5) = 29

This is true because,

(3x3) + (4x5) = 29

(9) + (20) = 29

29 = 29

Answer:

8

Step-by-step explanation:

Substitute the values in the expression, we have:

\(\displaystyle{|-1-3|+4}\)

Evaluate:

\(\displaystyle{|-4|+4}\)

Any real numbers in the absolute sign will always be evaluated as positive values. Thus:

\(\displaystyle{|-4|+4 = 4+4}\\\\\displaystyle{=8}\)

Hence, the answer is 8. A quick note that z-value is not used due to lack of z-term in the expression.

Answer:

more than 3 I think

Step-by-step explanation:

For the given distribution, the Expectation, E(2X² + 3X) is 28.9

Now here we see that we have the distribution given to us

We need to find

E(2X² + 3X)

Now we know that

E(X) = ∑xp(x)

Hence we get

E(2X² + 3X) = 2[1 X 0.2  +  4 X 0.3  +  9 X 0.2  +  16 X 0.4] + 3[1 X 0.2  +         2 X 0.3  +  3 X 0.2  +  4 X 0.4]

= 2[0.2 + 1.2 + 1.8 + 6.4] + 3[0.2 + 0.6 + 0.6 + 1.6]

= 2 X 9.6  +  3 X 3

= 19.2 + 9

The probability of selecting five balls with numbers divisible by 3 or 7 is approximately 0.0251.

To find the probability of selecting five balls with numbers divisible by 3 or 7, follow these steps:

Determine the total number of ping pong balls.

There are 134 - 57 + 1 = 78 ping pong balls in total.

Find the number of balls that are divisible by 3 or 7.

There are 26 numbers divisible by 3 (from 57 to 134), and 11 numbers divisible by 7 (from 57 to 134). However, there are

3 numbers divisible by both 3 and 7, so there are 26 + 11 - 3 = 34 balls that are divisible by either 3 or 7.

Calculate the probability of selecting one ball that is divisible by 3 or 7.

The probability of selecting one ball that is divisible by 3 or 7 is 34/78.

Calculate the probability of selecting five balls that are all divisible by 3 or 7.

Since we are selecting five balls, the probability would be

(34/78) × (33/77) × (32/76) × (31/75) × (30/74) = 0.02512

(rounded to five decimal places). Round the final answer to four decimal places.

The probability of selecting five balls with numbers divisible by 3 or 7 is approximately 0.0251.

Step-by-step explanation:

Given equation

12 = -4(-6x - 3)

Divide -4 on both sides

12 / (-4) = -4(-6x - 3) / (-4)

-3 = -6x - 3

Add 3 on both sides

-3 + 3 = -6x - 3 + 3

0 = -6x

Divide -6 on both sides

0 / -6 = -6x / -6

The slope of the line is -4 / 5

The slope of the line is the ratio of the rise to the run, or rise divided by the run.

The slope of a line is the change in y divided by the change in x.

Therefore,

slope = change in y / change in x

slope = y₂ - y₁ / x₂ - x₁

Therefore,

(2, -3)(-3, 1)

y₂ = 1

y₁ = -3

x₁ = 2

x₂ = -3

Therefore,

slope = 1 + 3 / -3 - 2

slope = 4 / -5

slope = - 4 / 5

A set is mathematically represented in a straightforward way using roster notation. The elements (or members) of a set are listed in a row inside the curly brackets in the roster form. If the set contains more than one element, a comma is used in a roster notation to indicate the separation of every two elements. A list of the elements of a set, each separated by a comma, enclosed in a set of curly brackets, can be used to describe the contents of the set.

Using the constant of proportionality the value of x when y is 72 is 9.

What is a COP?

The ratio between two quantities that are directly proportional is the constant of proportionality. When two quantities grow and shrink at the same rate, they are directly proportional.

If y varies directly as x, it means that y can be expressed as a constant multiple of x, i.e., y = kx, where k is the constant of proportionality.

To find k, we can use the given information that y = 48 when x = 6 -

y = kx

48 = k(6)

k = 8

Now that we know k, we can use it to find x when y = 72 -

y = kx

72 = 8x

x = 9

Therefore, when x = 72, the value of x = 9.

Answer:

B. 504 units²

Step-by-step explanation:

We multiply 6 and 8, we don't need to divide by 2 since there are two congruent triangles. That gets us 48. Now, we multiply 19 and 8. That gets us 152. Now, we multiply 6 and 19. That gets us 114. We have found the area of all sides but one. To do this one, we need to calculate the hypotenuse of the triangle. The following screenshot has the formula to calculate hypotenuse. If a is equal to 6, and b is equal to 8, we can do this formula. 6² is 36, and 8² is 64. Now, we add 36 and 64. That gets us 100. The square root of 100 is 10. That means the hypotenuse of this triangle is 10. Now, we multiply 10 and 19 to get 190. Now, we add up the area of all the sides (48 + 152 + 114 + 190). That gets us 504. That means B is our answer.

Based on the cost of her items, if Kim hands over $100, she will get back $9.85.

The total that Kim will pay includes the cost of all three items as well as the sales tax.

The total cost of the three items is:

= Blouse + Skirt + Purse

= 17.16 + 28.19 + 35.14

= $80.49

The total including the sales tax will be:

= Cost + (Cost x Sales tax)

= 80.49 + (80.49 x 12%)

= $90.15

The change she will get is:

= 100 - 90.15

Continuous random variable is a random variable that can take on a continuum of worth. In alternative words, a random variable is said to be continuous if it supposes a value that falls between a particular interval.

A continuous random variable can be described as a random variable that can take on an infinite number of possible values. Due to this, the probability that a continuous random variable will take on a fixed value is 0.

The probability density function of a continuous random variable can be explained as a function that gives the probability that the value of the random variable will drop between a range of values. Let X be the continuous random variable, then the formula for the pdf, f(x).
