someone PLEASE help me. this is an area of sectors problem and im confused.

explaining your answer = brainliest/five stars

The radius of a circle is 6 feet. What is the area of a sector bounded by a 126° arc?

give your exact answer in SIMPLEST FORM

Given:

Area of a rectangle = [tex]x^3-5x^2+3x-15[/tex]

Width of rectangle = [tex]x^2+3[/tex]

To find:

The length of the rectangle.

Solution:

The area of a rectangle is:

[tex]A=l\times w[/tex]

Where, l is length and w is the width.

It is can be written as:

[tex]\dfrac{A}{w}=l[/tex]

[tex]l=\dfrac{A}{w}[/tex]

Putting [tex]A=x^3-5x^2+3x-15[/tex] and [tex]w=x^2+3[/tex], we get

[tex]l=\dfrac{x^3-5x^2+3x-15}{x^2+3}[/tex]

[tex]l=\dfrac{x^2(x-5)+3(x-5)}{x^2+3}[/tex]

[tex]l=\dfrac{(x^2+3)(x-5)}{x^2+3}[/tex]

[tex]l=x-5[/tex]

Therefore, the length of the rectangle is [tex]x-5[/tex].

Step-by-step explanation:

2+5/2 is hard to add since first you have to make 2 into a fraction with the denominator 2. If you use the associative property, you can just easily combine -1/2 and 5/2 without any converting into fractions

Answer:

Step-by-step explanation:

8(2 + x) = 3x + 16 + 5x

=> 16 + 8x = 3x + 16 + 5x

=> 8x - 3x - 5x = 16 - 16

=> 0x = 0

=> x = 0 (Ans)

Answer:0

Step-by-step explanation:

everything cancels out

$138.00

Step-by-step explanation:

Steven earns in 4 hours -$23.00

he earns in 6 hours-$34.50

there fore in 10 hours -23.00+34.50=$57.50

in 20 hours -57.50+57.50=$115

and in 4 hours-$23.00+115.00=138.00$

then he earn $138.00 one day

Yes

Step-by-step explanation:

Try it.

Answer: 1st: No, 2nd: No, 3rd: Yes, 4th: Yes

Step-by-step explanation: You only flip the inequality when you divide a negative number on both sides. The only reason why you would divide would be to get the variable by itself -  in this case the coefficient would need to be negative. That only applies to the third and 4th equations.

Answer:

Around 376.99

Step-by-step explanation:

the formula is 2πrh+2πr²

so if we plug in everything we get 2π(4)(11)+2π(4)²

When we simplify that, we would get 376.99

Answer:

6.25 cups of sugar

Step-by-step explanation:

Let's make a proportion expression:

2.5/48 = x/120

Let x be the amount of sugar needed to make 120 sugar cookies.

Cross multiply:

120*2.5=48x

48x=300

x=6.25

So, you would need 6 1/4 cups or 6.25 cups of sugar to make 120 sugar cookies.

Answer:

Diameter: 10.8 cm

Circumference (in terms of π): 10.8π cm

Circumference (approximate): 33.91 cm

Step-by-step explanation:

Hi there!

We're given:

1) Determine the diameter

[tex]d=2r[/tex]

Multiply the radius 5.4 cm by 2

5.4 × 2 = 10.8

Therefore, the diameter of the circle is 10.8 cm.

2) Determine the circumference of the circle

[tex]C=\pi d[/tex]

Plug in the diameter 10.8

[tex]C=10.8\pi[/tex]

Therefore, the circumference of the circle in terms of π is 10.8π cm.

3) Determine the approximate circumference of the circle

[tex]C=10.8\pi\\C=10.8(3.14)\\C=33.91[/tex]

Therefore, the approximate circumference of the circle is 33.91 cm.

I hope this helps!

Answer:

The degree of the polynomial ≈ 4

Step-by-step explanation:

The degree of a polynomial, is given by the highest value of the sum of the exponents (powers) of the of the variables (monomials) that are present in the polynomial expression

The given polynomial expression is x²·y² + y³ + 4

The sum of the exponents; 2 + 2 = 4, and 3

The sum of exponents 4 > 3

Therefore, the degree of the polynomial = 4.

Answer:

There are 24 girls in the class.

Step-by-step explanation:

Write out the problem like this:

40 = (g-8)+(g)

40 is the total amount of students. (g) is the unknown number of girls in the class, and (g-8) is the amount of boys since there are 8 fewer boys than girls.

First, eliminate the parentheses.

40 = g - 8 + g

Next, combine like terms. Both g's are positive, to we get 2g

40 = g - 8 + g

40 = 2g - 8

Then, add 8 to both sides of the equation, because the 8 that was already present is negative and needs to be canceled out.

40 + 8 = 2g - 8 + 8

48 = 2g

Lastly, divide both sides by 2, so that the (g) is by itself.

40/2 = 24, 2g/2 = g

g=24

This can be tested as the correct answer by subtracting 8 from 24 to count the boys...

24 - 8 = 16

...and adding the two amounts together to get the total amount of students.

24 + 16 = 40

There are 24 girls in the class.

Answer and Step-by-step explanation:

2x + 2 is the answer.

If the boy is twice as old, and the sister's age is represented by x, then we multiply 2 to x to represent the boy's age.

Then we add 2 when 2 years pass by.

Answer: 500

Step-by-step explanation:

Given

6 g butter is required to make a cupcake

If there is 3 kg butter

We know, 1 kg is equivalent to 1000 g i.e. 3 kg is 3000 gm

No of cup-cakes made

Answer:

7.5 bag

Step-by-step explanation:

Carton #1: 19 berries

Carton #2: 26 berries

^^add them up together to get hte total amount of berries! 19 + 26 = 45

She has 45 berries in total, then you divid it by 6 aka the amount of berries she wants in each bag 45 ÷ 6 = 7.5

When she divids them up she has 7 bags with 6 berries in each and 1 bag with 3 berries.

Step-by-step explanation:

Volume of a circular cone : pi*r^2*h/3

I applied the formula to find these answers

Answer:

V = 75 pi

Step-by-step explanation:

We know the volume of a cylinder is given by

V = pi r^2 h where r is the radius and h is the height

V = pi ( 5)^2 (3)

V = pi (25)(3)

V = 75 pi

===============================================

Work Shown:

r = 5 is the radius

h = 3 is the height

V = pi*r^2*h .... volume of a cylinder

V = pi*5^2*3

V = pi*25*3

V = pi*75

V = 75pi ..... exact volume in terms of pi

V = 75*3.14

V = 235.5

If you used the approximation pi = 3.14, then the approximate volume is about 235.5 cubic units. Use more decimal digits of pi to get a more accurate answer.

Note how the pi*r^2 portion represents the area of the circular base. So we can say

volume = (area of base)*(height)

Answer:

Quinn's Taxi Service

Step-by-step explanation:

a) Yesterday, 37% of the drivers for Quinn's Taxi Service worked.

Hence, the percentage for Quinn's Taxi Service drivers that are working is 37%

b) At Bella's Taxi Express, 3 out of 10 drivers worked.

The percentage for Bella's Taxi drivers that are working is calculated as:

3/10 × 100

= 30%

Therefore, the taxi service that had a greater percentage of its drivers working is Quinn's Taxi Service with a high percentage of 37%

Answer:

3.754 • 10^-4

Step-by-step explanation:

Put decimal point back until in front of a whole number( not zero ;D). So it would be 3.754 and since it was going left or backwards the exponent would be negative. Therefore, giving our answer!
