Answers

Answer:

3.9 inches

Step-by-step explanation:

area of a circle = πr²

= π 3²

= 9 π

9π = 28.3 (rounded).

area of a square = length x width

= 6 x 6

= 36 inches

36 - 28.3

= 7.7

÷2 to get the individual value

= 3.9 inches rounded

The area of the yellow region will be  [tex]3.86[/tex] squared inches.

What is area ?

Area is the space occupied by any shape.

Area of the square [tex]=side*side[/tex]

We have,

A square of [tex]6[/tex] inch in side, divided in two semi-circles.

Radius of semi-circle[tex]=3[/tex] inch

Now,

Area of the square [tex]=side*side=6*6=36[/tex] squared inches

Now,

Area of a semi-circle[tex]= \frac{\pi }{2}r^{2}=\frac{22 }{2*7} (3)^2=14.14[/tex] squared inches

So,

Area of two semi-circles[tex]=28.28[/tex] squared inches

Now,

Area of yellow part [tex]= \frac{36-28.28}{2}=3.86[/tex] squared inches

So, Area of yellow part is [tex]3.86[/tex] squared inches find out by dividing by two because other part is equals to yellow part.

Hence, we can say that the area of the yellow region will be  [tex]3.86[/tex] squared inches.

The number of full test tubes Russel fill with water must be discrete number and not rational. 36 test tubes is the answer.

How to Know Cylinder Volume ?

Volume of a cylinder can be known either by the use of formula (V = πr²h) or by measuring with the volume of a known liquid.

Given that Russel is doing an experiment for a science fair project. He fills a beaker with water three times. He puts 16.5 milliliters of water in each test tube. How many full test tubes can Russel fill with water?

1. Describe one way to estimate the solution to this problem.

By dividing the amount of milliliters of water in the baker by 16.5 ml

2. Russel calculates correctly and says the answer to the problem is 36.36 test tubes. Is Russel's answer reasonable?

No! The reason is based on the fact that the answer must be a whole number and not a decimal number since the question centered on number of full test tubes filled with water.

Therefore, the correct answer should be 36 test tubes.

Para festeja su cumpleaños,Nancy compró 15 paquetes de pizzetas. Si cocinó 288 pizzetas, cuántos paquetes completos le quedaron?

Answers

Answer:

Nancy consumió 12 paquetes de pizzetas y le quedaron 3 paquetes completos.

Step-by-step explanation:

En primer lugar, debemos descomponer el número total de pizzas como una multiplicación de números primos. Al realizar la descomposición factorial tenemos que:

[tex]288 = 2 \times 2 \times 2 \times 2 \times 2 \times 3 \times 3[/tex]

Entonces, los familia de divisores de 288 es el siguiente conjunto:

[tex]D_{288} = \{2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144 \}[/tex]

Si tanto la cantidad de paquetes de pizzetas y la cantidad cocinada de pizzetas son números enteros y positivos, siendo la última mucho mayor. Entonces, la cantidad de pizzetas debe ser un número entero y la cantidad de paquetes gastados menor a la cantidad de paquetes comprados y el número entero más cercano a esa cantidad. Entonces, concluimos que Nancy se gastó 12 paquetes de pizzetas, quedándole 3 paquetes completos.

What quadrant does (-a,b) belong

Answers

Coordinate (-a , b ) belongs to second quadrant.

What is a Quadrant?

The axes (x-axis and y-axis) of a two-dimensional Cartesian plane system divide the plane into four infinite regions called quadrants. The horizontal line or x-axis and vertical line or y-axis intersect each other at the right angle.  The intersection of two lines is known to be the reference point. All the measurement is done by taking this point as the reference (or starting point) in the coordinate system.

"A quadrant is simply defined as the region of a cartesian plane formed when the x-axis and y-axis intersect each other."

Given, Coordinate ≡ (-a , b)

1st Quadrant: The upper right-hand corner of the graph is the first quadrant. In this quadrant the values of x and y both are positive.

2nd Quadrant: The upper left-hand corner of the graph is the second quadrant. In this quadrant, the value of x is negative whereas the value of y is positive.

3rd Quadrant: The lower left-hand corner of the graph is the third quadrant. It contains the negative values of both x and y.

4th Quadrant: Finally, the fourth quarter is at the lower right-hand corner, which has a positive value of x and a negative value of y.

Hence, by the above observation, given coordinate (-a, b) belongs to the 2nd quadrant.

A family buys 5 airline tickets online. The family buys travel insurance that costs ​$16 per ticket. The total cost is ​$840. Let x represent the price of one ticket. Write an equation for the total cost. Then find the price of one ticket.

Answers

If travel insurance for 1 ticket = $16
Travel insurance for 5 tickets = $16 * 5 = $80
If the price of 1 ticket = x
The price of 5 tickets = 5 * x = 5x
The total cost of tickets and insurance = $840
5x + 80 = 840
Subtract 80 from both sides
5x + 80 - 80 = 840 - 80
5x = 760
Divide both sides by 5
5x/5 = 760/5
x = 152
The price of 1 ticket is $152
Let’s check if x = 152 is a solution for 5x + 80 = 840
5(152) + 80 = 840
760 + 80 = 840
840 = 840

What is probability?Mathematical explanations of the likelihood that an event will occur or that a statement is true are referred to as probabilities. A number between 0 and 1 represents the likelihood of an event, with 0 generally denoting impossibility and 1 denoting certainty. How likely something is to occur is known as its probability. We can discuss the probabilities of various outcomes—how likely they are—when we aren't sure how a particular event will turn out. Statistics describes the examination of events subject to probability. The probability of anything occurring is known as probability. To determine probability, divide the total number of possible outcomes by the number of possible ways an event could occur.
