17. The length of segment BC is approximately 45.0.

18. Angle B is approximately 26.0 degrees.

15. The length of segment DF "e" is approximately 12.9.

Step-by-step explanation:

By the law of sine, the sine of interior angles of a triangle are proportional to the length of the side opposite to that angle.

For triangle ABC:

[tex]\sin{A} = \sin{103\textdegree{}}[/tex],The opposite side of angle A [tex]a = BC = 26[/tex], The angle C is to be found, andThe length of the side opposite to angle C [tex]c = AB = 6[/tex].

[tex]\displaystyle \frac{\sin{C}}{\sin{A}} = \frac{c}{a}[/tex].

[tex]\displaystyle \sin{C} = \frac{c}{a}\cdot \sin{A} = \frac{6}{26}\times \sin{103\textdegree}[/tex].

[tex]\displaystyle C = \sin^{-1}{(\sin{C}}) = \sin^{-1}{\left(\frac{c}{a}\cdot \sin{A}\right)} = \sin^{-1}{\left(\frac{6}{26}\times \sin{103\textdegree}}\right)} = 13.0\textdegree{}[/tex].

Note that the inverse sine function here [tex]\sin^{-1}()[/tex] is also known as arcsin.

17

By the law of cosine,

[tex]c^{2} = a^{2} + b^{2} - 2\;a\cdot b\cdot \cos{C}[/tex],

where

[tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] are the lengths of sides of triangle ABC, and[tex]\cos{C}[/tex] is the cosine of angle C.

For triangle ABC:

[tex]b = 21[/tex],[tex]c = 30[/tex], The length of [tex]a[/tex] (segment BC) is to be found, andThe cosine of angle A is [tex]\cos{123\textdegree}[/tex].

Therefore, replace C in the equation with A, and the law of cosine will become:

[tex]a^{2} = b^{2} + c^{2} - 2\;b\cdot c\cdot \cos{A}[/tex].

[tex]\displaystyle \begin{aligned}a &= \sqrt{b^{2} + c^{2} - 2\;b\cdot c\cdot \cos{A}}\\&=\sqrt{21^{2} + 30^{2} - 2\times 21\times 30 \times \cos{123\textdegree}}\\&=45.0 \end{aligned}[/tex].

18

For triangle ABC:

[tex]a = 14[/tex],[tex]b = 9[/tex], [tex]c = 6[/tex], andAngle B is to be found.

Start by finding the cosine of angle B. Apply the law of cosine.

[tex]b^{2} = a^{2} + c^{2} - 2\;a\cdot c\cdot \cos{B}[/tex].

[tex]\displaystyle \cos{B} = \frac{a^{2} + c^{2} - b^{2}}{2\;a\cdot c}[/tex].

[tex]\displaystyle B = \cos^{-1}{\left(\frac{a^{2} + c^{2} - b^{2}}{2\;a\cdot c}\right)} = \cos^{-1}{\left(\frac{14^{2} + 6^{2} - 9^{2}}{2\times 14\times 6}\right)} = 26.0\textdegree[/tex].

15

For triangle DEF:

The length of segment DF is to be found, The length of segment EF is 9, The sine of angle E is [tex]\sin{64\textdegree}}[/tex], andThe sine of angle D is [tex]\sin{39\textdegree}[/tex].

Apply the law of sine:

[tex]\displaystyle \frac{DF}{EF} = \frac{\sin{E}}{\sin{D}}[/tex]

[tex]\displaystyle DF = \frac{\sin{E}}{\sin{D}}\cdot EF = \frac{\sin{64\textdegree}}{39\textdegree} \times 9 = 12.9[/tex].

A rectangular prism with a volume of 5 cubic units is filled with cubes with side lengths of 1/3 units. How many 1/3 ?unit cubes does it take to fill the prism?

Answers

Answer:

135

Step-by-step explanation:

The little cubes with side length 1/3 unit have volume (1/3 unit)³ or (1/27 unit)³.  Divide the prism volume (5 units³) by (1/27 units³) to determine how many little cubes are required to fill the prism:

5 units³

--------------- = 135 little cubes.

1/27  unit

Note:  This assumes that the dimensions of the prism are such that there is no wasted space when all these little cubes are packed inside.  For example, if the width of the prism were 3, then we assume that 3 little cubes would fit that particular dimension.

There are 135 cubes in the cube with a volume of 5 cubic units and the small cube has a side length of 1/3 unit.

What is a cube?

It is defined as three-dimensional geometry that has six square faces and eight vertices.

As we know, the volume of the cube = side³

The volume of the rectangular prism = 5 cubic units

The volume of the small cube with side lengths of 1/3 unit is:

= (1/3)×(1/3)×(1/3)

= 1/27

The number of cubes in the big cube = 5/(1/27)

= 5×27

= 135 cubes

Thus, there are 135 cubes in the cube with a volume of 5 cubic units and the small cube has a side length of 1/3 unit.

D. m<GCB + m<CBE = 180°
E. m<BEG + m<EGC = 230°
F. The sum of all exterior angles of BEGC is equal to 360°.​

Answers

Answer:

The sum of all exterior angles of BEGC is equal to 360° ⇒ answer F only

Step-by-step explanation:

* Lets revise some facts about the quadrilateral

- Quadrilateral is a polygon of 4 sides

- The sum of measures of the interior angles of any quadrilateral is 360°

- The sum of measures of the exterior angles of any quadrilateral is 360°

* Lets solve the problem

- DEGC is a quadrilateral

∵ m∠BEG = (19x + 3)°

∵ m∠EGC = (m∠GCB + 4x)°

∵ The sum of the measures of its interior angles is 360°

∴ m∠BEG + m∠EGC + m∠GCB + m∠CBE = 360

∴ (19x + 3) + (m∠GCB + 4x) + m∠GCB + m∠CBE = 360 ⇒ add the like terms

∴ (19x + 4x) + (m∠GCB + m∠GCB) + m∠CBE + 3 = 360 ⇒ -3 from both sides

∴ 23x + 2m∠GCB + m∠CBE = 375

∵ The sum of measures of the exterior angles of any quadrilateral is 360°

∴ The statement in answer F is only true

Step-by-step explanation:

Janet can do a job in 3 hours while Garry can do the same job in 2 hours. If Janet works for an hour before Garry began helping her, how long will it take them to finish the job together?

Answers

Answer:

4/5 hour (48 minutes)

Step-by-step explanation:

Janet works at the rate of ...

(1 job)/(3 hours) = (1/3) job/hour

So, in 1 hour, she has worked 1/3 of the job, leaving 2/3 of the job remaining when Garry shows up.

Garry works at the rate of ...

(1 job)/(2 hours) = 1/2 job/hour

So, together they work at the rate of ...

(1/3 job/hour) + (1/2 job/hour) = (2/6 +3/6) job/hour = 5/6 job/hour

Then the time it takes to do the remaining 2/3 job is ...

(2/3 job)/(5/6 job/hour) = (2/3·6/5) hour = 4/5 hour

It will take 4/5 hour for them to finish the job together.

Answer: 4/5 of an hour or 48 minutes

Step-by-step explanation:

Janet's Rate : 1 job / 3 hours = 1/3 job/hour

In 1 hour, 1/3 of the job is already finished by her, so there is 2/3 of the job left.

Garry's Rate:

1 job / 2 hours = 1/2 job/hour

Janet an Garry's Rate:

1/3 job/hour + 1/2 job/hour = 2/6 +3/6 job/hour = 5/6 job/hour

Time to do remaining 2/3 of job:

2/3 job / 5/6 job/hour = 2/3 * 6/5 hour = 4/5 hour

Answer:

It will take 4/5 of an hour for them to finish the job together.

First differences are 3, 5, 7, 9, and the differences of these (2nd differences) are constant at 2. The degree of the polynomial function describing the sequence is equal to the number of the differences that are constant. Here, that is 2nd differences, so the sequences is described by a 2nd-degree (quadratic) polynomial.

The area of the base of a rectangular prism is 36 cm2. The height of the prism is 3 5 6 cm. What is the volume of the prism?

Answers

Answer:

138 cm³

Step-by-step explanation:

Given in the question that base of the rectangular prism = 36 cm²

Height of the prism = 3 5/6 cm = 23/6

We know that the volume of a rectangular prism with base area B and height H is given by

Volume = B(H)

Plug values in the formula above to find the volume of the prism

Volume = 36(23/6)

              = 6(23)

              = 138 cm³

So the volume of prism = 138 cm³

Answer:

108 cm³, 138 cm³, 180 cm³, 216 cm³

Step-by-step explanation:

I'm not if you meant to calculate three possible volumes for the prism, for heights of 3, 5 and 6 cm or if it was meant as 3 5/6... so I prepared you all the answers below.

Normally, the volume of a prism is calculated with Length x Width x Height.  The (Length x Width) part is form the base of the prism.  Since we already have that base measurement, we'll use the formula: Base x Height

So, if you meant 3 different calculations (for heights 3, 5 and 6 cm):

V = Base x Height

For a height of 3 cm, we have: V = 36 x 3 = 108 cm³

For a height of 5 cm, we have: V = 36 x 5 = 180 cm³

For a height of 6 cm, we have: V = 36 x 6 = 216 cm³

If however, you meant a single measure with 3 5/6:

For a height of 3 5/6 cm (23/6), we have: V = 36 x 23/6 = 6 * 23= 138 cm³

P(Male or Type B) > P(Male | Type B) P(Male or Type B) = P(Male | Type B) P(Male or Type B) < P(Male | Type B) There is not enough information.

Answers

Answer:

P(Male or Type B) > P(Male | Type B)

Step-by-step explanation:

Total Female = 85 type A, 12 type B  ⇒ 97 Female.

Total Male = 65 type A, 38 type B   ⇒ 103 Male

Total type A = 65 + 85 = 150

Total type B = 12 + 38 = 50

total number of people = 97 + 103 = 200

Then the probability would be:

P(Male | Type B) = [tex]\frac{number of male in B}{total number of male}[/tex]

                           = [tex]\frac{38}{103}[/tex]

                           = 0.368

P(Male or Type B) = [tex]\frac{total number of male + (total number of people in B - total number of male in B)}{total number of male}[/tex]

                              =  [tex]\frac{103 + (50 - 38)}{200}[/tex]

                              = [tex]\frac{103 + 12}{200}[/tex]

                              = [tex]\frac{115}{200}[/tex]

                              = 0.575

 Hence, P(Male or Type B) > P(Male | Type B)

Answer:

Part a) [tex]y=400(2.5)^{x}[/tex]

Part b) [tex]3,814,697\ rice\ weevil\ population[/tex]

Part c)  [tex]16.1\ weeks[/tex]

Step-by-step explanation:

Part a) Write and simplify a formula that can be used to predict the rice weevil population for any week after the beginning of the study

we know that

100%+150%=250%=250/100=2.5

In this problem we have an exponential function of the form

[tex]y=a(b)^{x}[/tex]

where

a is the initial value

b is the base

y ----> is the rice weevil  population

x ----> the number of weeks

In this problem

a=400 rice weevils

b=2.5

substitute

[tex]y=400(2.5)^{x}[/tex]

Part b) Use the formula to predict the rice weevil population 10 weeks after the beginning of the study. Show your work

we have

[tex]y=400(2.5)^{x}[/tex]

so

For x=10 weeks

substitute

[tex]y=400(2.5)^{10}=3,814,697\ rice\ weevil\ population[/tex]

Part c) Use the formula to predict when the rice weevil population will reach 1,000,000,000.

we have

[tex]y=400(2.5)^{x}[/tex]

so

For y=1,000,000,000 rice weevil  population

substitute in the formula and solve for x

[tex]1,000,000,000=400(2.5)^{x}[/tex]

Simplify

[tex]2,500,000=(2.5)^{x}[/tex]

Apply log both sides

[tex]log(2,500,000)=x*log(2.5)[/tex]

[tex]x=log(2,500,000)/log(2.5)=16.1\ weeks[/tex]

A function assigns the values. The number of weeks it will take for the population of 400 to be 1,000,000,000 is 16.1 weeks.

What is a Function?

A function assigns the value of each element of one set to the other specific element of another set.

A.) Given there are 400  rice weevils at the beginning. And the population is expected to grow at a rate of 150% each week. Therefore, the function that can represent the population can be written as,

Population after n weeks = 400×(1+1.5)ⁿ = 400×(2.5)ⁿ

where n is the number of weeks.

B.) The population of the rice weevils after 10 weeks will be,

Population after 10 weeks = 400×(2.5)¹⁰ = 3,814,697.266 ≈  3,814,697

C.) The time needed for the population to reach 1,000,000,000 will be,

1,000,000,000 = 400(2.5)ⁿ

2,500,000 = 2.5ⁿ

n = 16.0776 ≈ 16.1 weeks

Hence, the number of weeks it will take for the population of 400 to be 1,000,000,000 is 16.1 weeks.

Tim throws a stick straight up in the air from the ground. The function h = –16t2 + 48t models the height, h, in feet, of the stick above the ground after t seconds. Which inequality can be used to find the interval of time in which the stick reaches a height of more than 8 feet?

Answers

The inequality that can be used to find the interval of time in which the stick reaches a height of more than 8 feet is  -[tex]16t^2 + 48t > 8[/tex]

To solve this inequality, let's rearrange it:

-[tex]16t^2 + 48t - 8 > 0[/tex]

Now, we have a quadratic inequality. To solve it, we'll first find the critical points by setting the expression equal to zero:

[tex]-16t^2 + 48t - 8 = 0[/tex]

Now, we'll use the quadratic formula to find the roots:

[tex]t = [ -b ± √(b^2 - 4ac) ] / (2a)[/tex]

Where a = -16, b = 48, and c = -8.

Plugging in these values, we get:

[tex]t = [ -48 ± √(48^2 - 4(-16)(-8)) ] / (2(-16))[/tex]

[tex]t = [ -48 ± √(2304 - 512) ] / (-32)[/tex]

[tex]t = [ -48 ± √(1792) ] / (-32)[/tex]

[tex]t ≈ [ -48 ± 42.35 ] / (-32)[/tex]

Now, we have two critical points:

t1 ≈ (-48 + 42.35) / (-32) ≈ 0.186

t2 ≈ (-48 - 42.35) / (-32) ≈ 2.814

Now, we'll test intervals between and outside these critical points to determine when the inequality is satisfied:

For t < 0.186: The quadratic term dominates, leading to a negative value.

For 0.186 < t < 2.814: The quadratic term dominates, leading to a positive value.

For t > 2.814: The linear term dominates, leading to a negative value.

So, the solution to the inequality is 0.186 < t < 2.814.

Thus, the stick reaches a height of more than 8 feet between approximately 0.186 seconds and 2.814 seconds.

Solution :-

As per the provided information in the given question, we have been given that the radius of the sphere is 5 units. We have been asked to find or calculate the surface area of the sphere.

To calculate the surface area of the sphere, we will apply the formula below :-

[tex]\bigstar \:\:\:\boxed{\sf{\:\:Surface \: Area_{(Sphere)} = 4\pi r^2 \:\:}}[/tex]

Substitute the given values into the above formula and solve for surface area :-

[tex]\sf:\implies Surface \: Area_{(Sphere)} = 4\pi r^2[/tex]

[tex]\sf:\implies Surface \: Area_{(Sphere)} = 4 \times \pi \times \: (5 \: units)^2[/tex]

[tex]\sf:\implies Surface \: Area_{(Sphere)} = (5 \: units)^2 \times 4 \times \pi[/tex]

[tex]\sf:\implies Surface \: Area_{(Sphere)} = 25 \: units^2 \times 4 \times \pi[/tex]

[tex]\sf:\implies Surface \: Area_{(Sphere)} = 100 \: units^2 \times \pi[/tex]

[tex]\sf:\implies \bold{Surface \: Area_{(Sphere)} = 100\pi \: units^2}[/tex]

Therefore :-

The surface area of the sphere is 100π units². Thus, the 2nd option, B makes it as the correct answer.

Answer:

  10.8 ft

Step-by-step explanation:

The height from the base can be found from the formula for the volume. Fill in the given information and solve for the height.

  V = (1/3)Bh = (1/3)s²·h

  432 ft³ = (1/3)(12 ft)²·h . . . . . fill in side length and volume

  h = 432 ft³/(48 ft²) = 9 ft . . . divide by the coefficient of h

The slant height is the hypotenuse of a right triangle with this height as one leg and half the side length as the other leg.

  slant height = √((9 ft)² +(12 ft/2)²) = √(117 ft²) = 3√13 ft

  slant height ≈ 18.817 ft ≈ 18.8 ft
