ABCD is a square of side length 15cm. APC and AQC are arcs of the circles with centres D and B. Calculate the area of the unshaded part?

Answers

The area of the shadedregion is 96.75 cm².

What is a square?

A square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is side²

We have,

Square:

Side = 15 cm

Area of a circle = πr²

APC and AQC are arcs of the circles with centers D and B.

If we remove 1/4 of the area of the circle from the circle we get one part of the unshaded region.

There are two similar unshaded parts.

Now,

The area of the unshaded part.

= 2 (side² - (1/4)πr²)

= 2 (15² - 1/4 x 3.14 x 15²)

= 2 x 15² (1 - 0.785)

= 2 x 225 x 0.215

= 96.75 cm²

Thus,

The area of the shadedregion is 96.75 cm².

What is the quotient of 6.39 divided by 0.3?

Answers

Answer: 21.3

Step-by-step explanation:

Hi, a quotient is the quantity produced by the division of two numbers.

In this case the numbers are 6.39 and 0.3. So the result is the next calculation:

6.39 ÷ 0.3 = 21.3

The quotient of 6.39 divided by 0.3 is 21.3.

6.39 / 0.3 = 21.3 <====

Eqyivalent expresion to 3√m^2n^5

Answers

The first step to solving this expression is to factor out the perfect cube
$\sqrt[3]{m^(2) n^(3) X n^(2) }$
The root of a product is equal to the product of the roots of each factor. This will make the expression look like the following:
$\sqrt[3]{ n^(3) }$ $\sqrt[3]{ m^(2) n^(2) }$
Finally,, reduce the index of the radical and exponent with 3
n $\sqrt[3]{ m^(2) n^(2) }$
This means that the correct answer to your question is n $\sqrt[3]{ m^(2) n^(2) }$ .

Tanesha’s utility and telephone bills for the month totaled $150. The utility billwas 4 times as much as the telephone bill. How much was each bill?

Answers

X represents the cost of the phone bill

4x + x = 150
5x = 150
X = (150/5)
X = 30

Therefore the telephone is $30 and the utility bill is $120

What is the study of mathematical probabilities, distributions and deviations?

Answers

Statistics. Statistics is a branch of mathematics which is the scientific study of mathematical values pertaining to qualitative descriptions and transcribe them into quantifying values such as the descriptive statistics and infuses these quantities in the field of inferential statistics. In these two categories involve probabilities, distribution and deviations which are mainly compositions of the descriptive statistics. Inferential statistics will involve comparison and variation of the given values. Methods are t-test, analysis of variance, and two-way analysis of variance and other methods.

O 40.0%

Answers

The probability of chosen student choosing apple wedges and he is from high school is 9% so option (A) is correct.

What is probability?

The probability of an event occurring is defined by probability.

Probability is also called the chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.

Do not take underestimate probability it has several uses in daily life whether forecasts or like that.

In our daily time, there are several instances in the everyday world where we may need to draw conclusions about how everything will turn out.

Probability of choosing apple wedges and he is from high school ⇒

P(Apple wedge and high school) = P(Apple wedge) × P(high school/apple wedge)

Now,

Probability = desired/total

So,

P(Apple wedge) = 90/400

Now,

P(high school/apple wedge) = 36/90

So,

P(Apple wedge and high school) = (90/400) × (36/90)

P(Apple wedge and high school) = 0.09 ⇒ 9%

Hence "The probability of chosen student choosing apple wedges and he is from high school is 9%".
