The radius of a circle is 1 centimeter. What is the area of a sector bounded by a 90° arc?

Answers

Answer 1

Answer:

[tex]Area = 0.785cm^2[/tex]

Step-by-step explanation:

Given

[tex]r = 1cm[/tex] -- radius

[tex]\theta = 90^{\circ}[/tex]

Required

Determine the area of the sector

This is calculated as:

[tex]Area = \frac{\theta}{360} * \pi r^2[/tex]

Substitute values for r and [tex]\theta[/tex]

[tex]Area = \frac{90}{360} * \pi * (1)^2[/tex]

Simplify 90/360

[tex]Area = \frac{1}{4} * \pi * (1)^2[/tex]

[tex]Area = \frac{1}{4} \pi[/tex]

Take [tex]\pi[/tex] as 3.14

[tex]Area = \frac{1}{4} * 3.14[/tex]

[tex]Area = 0.785cm^2[/tex]

Complete question :

Joanna had four candy bars. She wanted to find out how many people could share the bars if each person received 2/3 of a bar. Use the candy bar picture below to help you.

What is the answer to Joanna's question?

Kindly find attached candy bar picture below

Answer:

6 people

Step-by-step explanation:

From the picture, each candy bar has already been divided equally into 3. Since we have 4 candy bars. The total number of divisions we have is ; (3 * 4 = 12 candy units).

Since each person is taking 2/3 of a bar, this is equal to 2 units of candy

Hence, number of people who could share the bar :

Total units or division / units person

12 / 2

= 6 people

A teacher has 396 pieces of candy. If there are 44 students, 6 of whom are boys, if divided evenly, how many pieces of candy will each student get?

Answers

Answer:

9 pieces of candy.

Step-by-step explanation:

The information about how many boys there are is irrelevant, so we can just ignore that.

The important information is that the teacher has 396 pieces of candy and that it is split between 44 students equally.

So, to solve, we just do 396 / 44 = 9.

Therefore, each student will get 9 pieces of candy.

Julio considers the reduction of the triangle. What is the correct cross product that he should use to solve for the missing dimension? (8)(12) = 21x (8)(21) = 12x (12)(8) = 12x (12)(21) = 8x

Answers

Answer:

(8)(21) = 12x

Step-by-step explanation:

(8)(12) = 21x

(8)(21) = 12x

(12)(8) = 12x

(12)(21) = 8x

Opposite : Adjacent

12 in : 21 in

Opposite : Adjacent

8 in : x in

Equate both ratios to solve for x

12 : 21 = 8 : x

12 / 21 = 8 / x

Cross product

(12)(x) = (21)(8)

12x = 168

x = 168 / 12

When you load 8 identical chairs into a crate, the total weight is 66 lbs. When you load 11 of those same chairs into the same crate, the total weight is 84 lbs.

How many lbs does the crate weigh?

How much does each chair weigh?

Answers

Answer:

each chair weighs 6 lbs and the crate weighs 18 lbs.

Step-by-step explanation:

The solution is: 6 lbs does the crate weigh and, 18 lbs does each chair weigh.

What is equation?

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

here, we have,

given that,

When you load 8 identical chairs into a crate, the total weight is 66 lbs. When you load 11 of those same chairs into the same crate, the total weight is 84 lbs.

let, each chair weigh = x

and, the crate weigh = y

so, we get,

the equations as:

8x + y = 66 ....(1)

11x + y = 84 ....(2)

now, solving this two equations,

we get,

subtracting (2) - (1),

3x = 18

or, x = 6

so, we have,

y = 18

Hence, The solution is: 6 lbs does the crate weigh and, 18 lbs does each chair weigh.

Given:

A figure.

To find:

The four line segments that have point B as an endpoint.

Solution:

If A and B are two points, then

Segment AB is written as [tex]\overline{AB}[/tex].

Ray AB is written as [tex]\overrightarrow{AB}[/tex]. It means B is not the end point and the line is moving up to infinite.

Line segments that have point B as an endpoint are [tex]\overline{BA},\overline{BC},\overline{BH},\overline{BE},\overline{BF}[/tex].

Only option B represents the four line segments that have point B as an endpoint.

Therefore, the correct option is B.

Can someone help me on 2/3-3/8 show work

Answers

Answer:

It is 7/24

Step-by-step explanation:

So first you want a common denominator so we have to find the least common multiple of 3 and 8, which is 24.

Next you have to multiply the same to the numerator, I usually go by the phrase whatever you do to the bottom you do to the top. So 8 times 2 is 16 and 3 times 3 is nine.

Everything changed should be 16/24-9/24

then we do 16-9 is 7 and you never subtract the denominators so 2/3-3/8 is 7/24

Jaylen used the seat number for each of the 6,500 fans' seats in the stands at a college football game and put the numbers in a computer program. He randomly chose 200 numbers and found that 36 of those people had also purchased a parking voucher. Estimate the number of fans in the stands at a sold-out football game that purchased a parking voucher. Explain.

Answers

Answer:

1170 seats

Step-by-step explanation:

Given

[tex]Seats = 6500[/tex]

From the computer program, we have:

[tex]Sample = 200[/tex]

[tex]Voucher = 36[/tex]

First, we calculate the proportion (p) of those that bought the voucher

[tex]Proportion = \frac{Voucher}{Sample}[/tex]

[tex]p = \frac{36}{200}[/tex]

[tex]p = 0.18[/tex]

Using the larger population (i.e. 6500 seats), the esitimate of people that have bought the voucher is then calculated as:

[tex]Estimate= Proportion * Seats[/tex]

[tex]Estimate= 0.18 * 6500[/tex]

[tex]Estimate= 1170[/tex]

What is additive inverse?

The additive inverse of a number is its opposite number. If a number is added to its additive inverse, the sum of both the numbers becomes zero. The simple rule is to change the positive number to a negative number and vice versa.

The additive inverse of the expression is -(expression).

Now, -(-9x+3)

= 9x-3
