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:

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.

32/50 = 0.64 * 100 = 64%

Step-by-step explanation:

The row 'girls' represents the population of girls who answered the survey. There were 50 total, and 32 answered for brand A. 32/50 is the fraction representing the number of the total girls which answered brand A.

Answer:

Option A, 64%

Step-by-step explanation:

Step 1:  Determine the percentage of girls that were surveyed that prefer Brand A cell phones

There are a total of 50 girl students and out of those 32 girls prefer Brand A cell phones.  This means that 32/50 = 64% of all the girl students prefer a Brand A phone.

Answer:  Option A, 64%

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

Answer:

Step-by-step explanation:

Total number of marbles = 5 + 2 + 3 = 10

Probability of choosing 1 green marble = 2/10

Probability of choosing 1 yellow marble = 3/10

Notice (and this is important) that the denominator didn't change. Why?

Because you replaced the first marble into the bag. That word replacement is critical in a problem of this nature. There is the term non replacement which means that the second draw would have a denominator of 9.

So what is the probability of P(green then yellow)?

P(green then yellow) = 3/10 * 2/10 = 6/100

Answer: P(green then yellow) = 3/50 because 6 / 100 reduces.

The expression that represents the height of the triangular base of the pyramid is given by: Option B: (5/2)√3 untis

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

[tex]|AC|^2 = |AB|^2 + |BC|^2[/tex]

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

The question is incomplete, and the upper part of the completed question is:
"The base of a solid oblique pyramid is an equilateral triangle with an edge length of 5 units. A solid oblique pyramid has an equilateral triangle base with an edge length of 5 units. "

The diagram of the base of the considered pyramid is attached below.

The perpendicular from A to BC is touching BC at C, and is bisecting it (it can be proved).

Consider the triangle ADB. It is a right angled triangle.

We need the length of AD which represents the height of the triangle ABC.

This is obtained using Pythagoras theorem as:

[tex]|AB|^2 = |AD|^2 + |DB|^2\\\\|AD|^2 = |AB|^2 - |DB|^2\\\\|AD| = \sqrt{5^2 - \left( \dfrac{5}{2}\right)^2}[/tex]

(took positive root because of |AD| being length, which is a non-negative quantity).

SImplifying it, we get:

[tex]|AD| = \sqrt{5^2 - \left( \dfrac{5}{2}\right)^2}\\\\|AD| = \sqrt{\dfrac{5^2(4-1)}{4}} = \dfrac{5\sqrt{3}}{2} = \dfrac{5}{2} \times \sqrt{3} \: \rm units[/tex]

Answer:

779

Step-by-step explanation:

Given Arithmetic series is: 150+143+136+…+(-102)+(-109)

Here,

First term (a) = 150

Common difference (d) = 143 - 150 = - 7

[tex]n^{th}\: term:\:a_n = -109[/tex]

The formula for [tex]n^{th}\: term[/tex] of an arithmetic series is given as:

[tex]a_n = a +(n-1)d[/tex]

Plugging the values of a, d and [tex]a_n[/tex] in the above formula, we will find the number of terms that exist from 150 to (-109)

[tex]-109 = 150+(n-1)(-7)[/tex]

[tex]\implies\: -109 -150=(n-1)(-7)[/tex]

[tex]\implies\: -259=(n-1)(-7)[/tex]

[tex]\implies\: \frac{-259}{-7}=(n-1)[/tex]

[tex]\implies\: 37=n-1[/tex]

[tex]\implies\: 37+1=n[/tex]

[tex]\implies\: n=38[/tex]

Thus, there are total 38 terms in the given Arithmetic series.

Now,

Sum of n terms of an arithmetic series is given by the formula: [tex]S_n=\frac{n}{2}(a +a_n)[/tex],

Plugging in the values, we find:

[tex]S_{38}=\frac{38}{2}[150 +(-109)][/tex]

[tex]\implies S_{38}=\frac{38}{2}[150 +(-109)][/tex]

[tex]\implies S_{38}=19[150 -109][/tex]

[tex]\implies S_{38}=19[41][/tex]

[tex]\implies S_{38}=779[/tex]
