Find BC in angle ABC
Round to the nearest tenth.

BC=?

Answer:

B: 27π units²

Step-by-step explanation:

[tex]\textsf{Area of a sector of a circle}=\left(\dfrac{\theta}{360^{\circ}}\right) \pi r^2[/tex]

where:

Given:

Substituting given values into the formula:

[tex]\begin{aligned}\implies \textsf{Area of a sector of a circle }& =\left(\dfrac{120^{\circ}}{360^{\circ}}\right) \pi \cdot 9^2\\ & = \dfrac13 \cdot \pi \cdot 81\\ & = 27 \pi\: \sf units^2\end{aligned}[/tex]

The area of the asked sector is 27π units².

A sector of a circle is a portion or part of a circle that is composed of an arc and its two radii.

Given that a circle L, we radius 9 and a central angle of 120°, we need to find the area of the sector, which is intercepted by the central angle,

So,

The area of a sector of a circle = central angle / 360° × area of the circle,

So,

A = 120°/360° × π × 9²

= 1/3π × 81

= 27π

Hence, the area of the asked sector is 27π units².

Answer:

what will be the price of the next model= 59,748

Step-by-step explanation:

7748 is 14.9% of 52000

Solution:

What is 14.9% of 52000?

Y is 14.9% of 52000

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 14.9% * 52000

Converting percent to decimal:

p = 14.9%/100 = 0.149

Y = 0.149 * 52000

Y = 7748

To find the price for the next model

7748 + 52000

=> 59,748

Step-by-step explanation:

=> No. of roses in a dozen = 12

=> No. of roses in half dozen = 12/2 = 6

=> No. of roses in 2 1/2 dozen = 2(12)+6 =30

Answer:

8/8 , 12/12, 16/16

Given:

A fraction 4/4.

To find:

An equivalent fraction to a given fraction.

Solution:

A fraction equivalent to 4/4 is 8/8.

To answer this question, first of all, we should know that the equivalent fractions of a number or value are the fractions having different numerators and denominators but when simplified they are all equal to the same value or number.

There is no limit to equivalent fractions of a given number.

Now,

we have,

a fraction 4/4,

To get its equivalent fraction, we will multiply the same number in its numerator and denominator.

Let's multiply 2 in both numerator and denominator of 4/4.

We get

4x2/4x2 = 8/8

So, an equivalent fraction to 4/4 is 8/8.

In notice of this 12/12 and 16/16

the solution is:

u should at the first find the volume of the small bag that V= LWH ( Lenght, width, height)

so it will be 82.5

since the Volume of the large bag is 2 times the volume of the small bag so the volume of large bag will be 165

so H = V / LW

H = 165 / 5×3

H = 165 / 15

So the Answer is H = 11

An expression has numbers, variables, and mathematical operations. The expression that represents the profit made by the organization is 5x-200.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

As it is given that the profit is the difference between the revenue and cost. Therefore, the expression that represents the profit can be written as,

[tex]\rm Profit = Revenue - Cost[/tex]

        [tex]= (3x^2+4x-60)-(3x^2-x+200)\\\\= 3x^2+4x-60-3x^2+x-200\\\\=5x-260[/tex]

Thus, the expression that represents the profit made by the organization is 5x-200.

In mathematics, a rational function is any function that can be defined by a rational fraction, which is an algebraic fraction such that both the numerator and the denominator are polynomials.

Answer: 4 yd, 130 in, 10ft

Step-by-step explanation:

So first you turn everything into inches

130 inches is already in inches.

4 yards = 12 ft

1ft = 12 in

12 *12 = 144 in

so 4 yards is 144 inches

10 ft = 12*10

12*10 = 120

so 10ft is 120 inches

144 inches is the greatest and 120 inches is the least.

The answer needs to be in the original form.
