Answer:

18pi, or 56.52

Step-by-step explanation:

To start off, if you were to find the area of any whole circle, you would use the formula: pi x radius^2 = area of circle

However, since this is a semi-circle (half of a whole circle) you would divide the whole expression by 2, and then solve:

(pi x radius^2)/2 = area of semi-circle

(pi x 6^2)/2 = area of semi-circle

(36 x pi)/2 = area of semi-circle

18 x pi = area of semi-circle

18 x 3.14 = area of semi-circle

56.52 = area of semi-circle

The area of a circle is

[tex]\pi \: {r}^{2} [/tex]

So the area of a semicircle would be half of that, or

[tex] \frac{\pi}{2} {r}^{2} [/tex]

So just plug in the radius, six, to get this

[tex]18\pi[/tex]

Answer:

8/225

Step-by-step explanation:

The probability of each event would be the number of the type of currency that you have specified divided by the total number of coins, in this case the total amount of coins does not change as the coin returns to the bag.

The total number of coins is: 10 + 12 + 8 = 30

The probability of finding a quarter is:

10/30

The probability of finding dime is:

8/30

The probability of finding nickel is:

12/30

The final probability then is:

(10/30) * (8/30) * (12/30) = 960/27000

If we simplify this, dividing both numbers by 120, we are left with:

8/225

Answer:

21

Step-by-step explanation:

(9g+4)-55=

(72+4)-55=

76-55=

21

Final answer:

To find the answer, first multiply 9 by 8, then add 4, resulting in 76. Finally, subtract 55 to get the answer, which is 21.

Explanation:

To solve the problem, we need to first calculate the sum of 9g and 4 when g=8. This will be 9 × 8 + 4.

After calculating the sum, we will subtract 55 from this amount to get the final answer.

Following the steps:

Therefore, when g = 8, subtracting 55 from the sum of 9g and 4 results in  21.

Here are the low temperatures (in degrees Fahrenheit) for one week in Montreal, Canada:

                          -3.5ºF, 5ºF, 1.5ºF, -0.5ºF, -2ºF, 2.5ºF, -4ºF

Compare the weather on two different days using an inequality. Then see if their comparisons change by finding the absolute value of each.

You have to choose two days at random and compare the values of temperature registered those days and compare them, for example:

Day 1: 3rd day: 1.5ºF

Day 2: 7nth day: -4ºF

Comparison of Day 1 and Day 2:

Remember:

"<" indicates that the value from the left is less than the value from the right.

">" indicates that the value from the left is greater than the value from the right.

The temperature registered on Day 1 is 1.5ºF and the temperature registered on Day 2 is -4ºF, as you notice the second temperature is negative and therefore is less than the first temperature:

                                            1.5ºF > -4ºF

Comparison of days with absolute value:

To compare absolute values you have to disregard the sign and consider only the number of the temperature:

|Day 1|= |1.5ºF|

|Day 2|= |4ºF|

Then the registered temperature of Day 1 is less than the registered temperature on Day 2:

                                              |1.5ºF| < |4ºF|

Answer :

9

Explanation :

The expression above signifies the Permutation expression

Permutation expression is given as nPr

The Permutation expression is calculated as:

nPr = P(n, r) = n! / (n - r)!

It the above question, we were asked to evaluate the expression 9P1

From the above question, we can see that:

n = 9 and r = 1

Therefore, the expression

9P1 = 9! / ( 9 - 1) !

9P1 = 9! / 8!

= 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 / 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1

= 362880 /40320

= 9

Therefore, the evaluation of the expression 9P1 = 9

Final answer:

To evaluate the expression 9P1, we calculate the permutation for selecting 1 item from 9, which simplifies to 9/1, giving us the answer of 9.

Explanation:

The student has asked to evaluate the expression 9P1, which is a permutation problem. To find 9P1, we use the permutation formula, which is P(n, k) = n! / (n-k)!, where n is the total number of items to choose from, and k is the number of items to choose. In this case, since we want to choose 1 item from 9, the permutation is calculated as:

Therefore, the value of 9P1 is 9.

Answer:

360.82 units

Step-by-step explanation:

The circle has a circumference of 1,133.54 units.

The circumference of a circle is given as:

C = πD

where D = diameter

This implies that:

1133.54 = πD

=> D = 1133.54 / π

D = 360.82 units

Its diameter is 360.82 units

Answer:

339604.65 cubic feet

Step-by-step explanation:

We are given that 1 m is equal to 3.3 ft.

1 m = 3.3 ft

This means that if we find the volume of a cube of 1 m, we have its volume as:

[tex]1^3 = 1 m^3[/tex]

In the same way, the volume of a cube of 3.3 ft (1 m) is:

[tex]3.3^3 = 35.937 ft^3[/tex]

This means that:

[tex]1m^3 = 35.937 ft^3[/tex]

The Kuroshio sea tank has volume of [tex]9450 m^3[/tex]. Its volume in cubic feet is therefore:

[tex]1m^3 = 35.937 ft^3\\\\9450 m^3 = 9450 * 35.937 = 339604.65 ft^3[/tex]

The volume of the tank is 339604.65 cubic feet.

Answer:

It will produce 6450 bicycles in 30 days

Aaron has 8 apples and Ben has 12 apples

Step-by-step explanation:

A)

A bicycle factory produces 1505 bicycles in a week.

No. of days in 1 week = 7

So, Number of bicycles produced in 7 days = 1505

Number of bicycles produced in 1 day =[tex]\frac{1505}{7}[/tex]

Number of bicycles produced in 30 days = [tex]\frac{1505}{7} \times 30=6450[/tex]

So, It will produce 6450 bicycles in 30 days

B)20 apples are distributed between Aaron and Ben in the ratio 2 : 3.

Let the ratio be x

So, Aaron has apples = 2x

Ben has apples = 3x

So, 2x+3x=20

5x=20

x=4

Aaron has apples = 2x =2(4)=8

Ben has apples = 3x =3(4)=12

Hence Aaron has 8 apples and Ben has 12 apples

Answer:

B. Opposite angles add up to 180 degrees.

Step-by-step explanation:

Answer Choice B is incorrect because opposite angles are actually congruent. However, adjacent angles of a parallelogram do add up to 180 degrees.

We have been given that in △CDE , CD=10 , DE=7 , and m∠E=62 degrees. We are asked to find the measure of angle D.

We will use law of sines to solve our given problem.

[tex]\frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)}[/tex], where, a, b and c are opposite sides to angles A, B and C respectively.

First of all we will find measure of angle C as:

[tex]\frac{7}{\sin(C)}=\frac{10}{\sin(62^{\circ})}[/tex]

[tex]\sin(C)=\frac{7\cdot \sin(62^{\circ})}{10}[/tex]

[tex]\sin(C)=\frac{7\cdot 0.882947592859}{10}[/tex]

[tex]\sin(C)=0.6180633150013[/tex]

Now we will use arcsin to solve for C as:

[tex]C=\sin^{-1}(0.6180633150013)[/tex]

[tex]C=38.174844995363^{\circ}[/tex]

[tex]C\approx 38.2^{\circ}[/tex]

Now we will use angle sum property to find measure of angle D.

[tex]\angle D+\angle C+\angle E=180^{\circ}[/tex]

[tex]\angle D+38.2^{\circ}+62^{\circ}=180^{\circ}[/tex]

[tex]\angle D+100.2^{\circ}=180^{\circ}[/tex]

[tex]\angle D+100.2^{\circ}-100.2^{\circ}=180^{\circ}-100.2^{\circ}[/tex]

[tex]\angle D=79.8^{\circ}[/tex]

Therefore, the measure of angle D is approximately [tex]79.8^{\circ}[/tex].

  Measure of angle D will be 79.8°.

          [tex]\frac{c}{\text{sinC}}= \frac{d}{\text{sinD}}= \frac{e}{\text{sinE}}[/tex]

        Here, c, d and e are the sides and C, D, E are the angles opposite

        to these sides of the given triangle.

Given in the question,

In ΔCDE,

CD = 10 units

DE = 7 units

m∠E = 62°

By applying sine rule,

[tex]\frac{7}{\text{sinC}}= \frac{d}{\text{sinD}}= \frac{10}{\text{sin(62)}}[/tex]

[tex]\frac{7}{\text{sinC}}= \frac{10}{\text{sin(62)}}[/tex]

[tex]\text{sin(C)}=\frac{\text{sin(62)}\times 7}{10}[/tex]

          [tex]=0.618063[/tex]

C = [tex]\text{sin}^{-1}(0.618063)[/tex]

C = 38.175°

   ≈ 38.2°

By triangle sum theorem of a triangle,

m∠C + m∠D + m∠E = 180°

38.2 + m∠D + 62° = 180°

m∠D = 79.8°

       Therefore, measure of angle D will be 79.8°.

the actual distance between the two towns is 360 miles.

The ratio used to depict the relationship between the dimensions of a model or scaled figure and the corresponding dimensions of the real figure or object is called the scale. On the other hand, a scale factor is a value that is used to multiply all of an object's parts in order to produce an expanded or decreased figure.

Given, On a map, the distance between two towns is 12 centimeters.

Also given, 3 centimeters represent 90 miles on the map.

Since 12 centimeters represent the distance between the two towns on the map, we can set up the proportion:

3 centimeters : 90 miles = 12 centimeters : x miles

where x represents the actual distance between the two towns in miles.

To solve for x, we can cross-multiply and simplify:

3 centimeters * x miles = 90 miles * 12 centimeters

3x = 1080

x = 360

Therefore, the actual distance between the two towns is 360 miles.

Answer:

Value of h greater than 5.4 will make inequality false.

Step-by-step explanation:

This question is incomplete; here is the complete question.

The Jones family has saved a maximum of $750 for their family vacation to the beach. While planning the trip, they determine that the hotel will average $125 a night and tickets for scuba diving are $75. The inequality can be used to determine the number of nights the Jones family could spend at the hotel 750 ≥ 75 + 125h. What value of h does NOT make the inequality true?

From the given question,

Per night expense (expected) = $125

If Jones family stays in the hotel for 'h' days then total expenditure on stay = $125h

Charges for scuba diving = $75

Total charges for stay and scuba diving = $(125h + 75)

Since Jones family has saved $750 for the vacation trip so inequality representing the expenses will be,

125h + 75 ≤ 750

125h ≤ 675

h ≤ [tex]\frac{675}{125}[/tex]

h ≤ 5.4

That means number of days for stay should be less than equal to 5.4

and any value of h greater than 5.4 will make the inequality false.

We have been given that the 5th term in a geometric sequence is 160. The 7th term is 40. We are asked to find the possible values of 6th term of the sequence.

We know that an geometric sequence is in form [tex]a_n=a\cdot r^{n-1}[/tex], where,

[tex]a_n[/tex] = nth term of sequence,

a = First term,

r = Common ratio,

n = Number of terms.

We will get two equations using our given information as:

[tex]160=a\cdot r ^{5-1}...(1)[/tex]

[tex]160=a\cdot r ^{4}...(1)[/tex]

[tex]40=a\cdot r ^{7-1}...(2)[/tex]

[tex]40=a\cdot r ^{6}...(2)[/tex]

Upon dividing equation (2) by equation (1), we will get:

[tex]\frac{40}{160}=\frac{a\cdot r^6}{a\cdot r^4}[/tex]

[tex]\frac{1}{4}=r^{6-4}[/tex]

[tex]\frac{1}{4}=r^{2}[/tex]

[tex]r^{2}=\frac{1}{4}[/tex]

[tex]\sqrt{r^{2}}=\pm\sqrt{\frac{1}{4}}[/tex]

[tex]r=\pm\frac{1}{2}[/tex]

Let us solve for a.

[tex]160=a\cdot (\frac{-1}{2})^{4}[/tex]

[tex]160=a\cdot \frac{1}{16}[/tex]

[tex]160\cdot 16=a\cdot \frac{1}{16}\cdot 16[/tex]

[tex]2560=a[/tex]

So our formula would be [tex]a_n=2560\cdot (\pm\frac{1}{2})^{n-1}[/tex].

We cannot determine whether the common ratio would be positive or negative, so we will take both values.

[tex]a_6=2560\cdot (\pm\frac{1}{2})^{6-1}[/tex]

[tex]a_6=2560\cdot (\pm \frac{1}{2})^{5}[/tex]

[tex]a_6=2560\cdot \pm \frac{1}{32}[/tex]

[tex]a_6=\pm 80[/tex]

Therefore, the 6th term of the sequence would be [tex]\pm 80[/tex] and option C is the correct choice.

Step-by-step explanation:

V = l*w*h for the rectangular  tank

V = 70* 40*40

  =112000 cm^3 = 1mL

The water is 84000

Make this a fraction

84000/112000  = 3/4

The water fills 3/4 of the tank

1-3/4 = 1/4

It is 1/4 from the top

Find the volume of the treasure chest

V = 12*10*8 =960

Tower

V = pi r^2

  3.14 * 10^2 *10

  =3140

Water + chest + tower

84000+960+3140 =88100

This is less than 112000 so the water will not overflow

Answer:

a) 10 cm

b) Will not overflow

Step-by-step explanation:

8400 = base area × height

84000 = 70 × 40 × h

h = 30

From the top: 40 - 30 = 10cm

b) Capacity of the tank:

70 × 40 × 40

112,000 cm³

Combined volume of the two vessels:

(12 × 10 × 8) + (3.14 × 10² × 10)

960 + 3140

4,100 cm³

4100 = 70 × 40 × rise

rise = 1.464285715 cm

Since 1.464285715 < 10
