The volume of an average stone in the outer circle of Stonehenge is calculated by multiplying the base area, 19.5 square feet, by the height, 13 feet, resulting in a volume of 253.5 cubic feet.

To calculate the volume of a stone from Stonehenge, which is shaped like a rectangular prism, we need to multiply the height of the stone by the base area. The height is given as 13 feet, and the base area is 19.5 square feet. The formula for volume V of a rectangular prism is

V = base area × height.

So, the volume V of one of the average stones in the outer circle of Stonehenge would be:

V = 19.5 sq ft  × 13 ft

V = 253.5 cubic feet

Therefore, the volume of the stone is 253.5 cubic feet.

The answer is [tex]\frac{4y}{y+3}[/tex]

See the attached figure

Answer:

[tex] \frac { 4y } { y + 3 } [/tex]

Step-by-step explanation:

We are given the following terms and we are to find their product:

[tex] \frac { 2y } { y - 3 } \times \frac { 4y - 12 } { 2y + 6 } [/tex]

[tex] \frac { 8y^2 - 24y } { 2y^2 - 6y + 6y - 18 } [/tex]

Taking the common terms out and cancelling them to get:

[tex] \frac { 2 (4y^2 - 12y ) } { 2 (y^2 - 9 ) } [/tex]

[tex] \frac { 4y ( y - 3 ) } { ( y + 3 ) ( y - 3 ) } [/tex]

[tex]\large\boxed{V=75\ in^3}[/tex]

Step-by-step explanation:

The formula ogf a volume of  a pyramid:

[tex]V=\dfrac{1}{3}BH[/tex]

B - area of a base

H - height

We have a base length a = 5 in and a height H = 9 in.

In the base we have a square. The formula of an area of a square is:

[tex]B=a^2[/tex]

Substitute:

[tex]B=5^2=25\ in^2[/tex]

Calculate the volume:

[tex]V=\dfrac{1}{3}(25)(9)=(25)(3)=75\ in^3[/tex]

Most likely I would pick B

Answer:

f(x) = log x – 1 ⇒  x-intercept = (10 , 0)

f(x) = -(log x – 2) ⇒ x-intercept = (100 , 0)

f(x) = log(-x – 2) ⇒ x-intercept = (-3 , 0)

f(x) = -log -(x – 1) ⇒ x-intercept = (0 , 0)

Step-by-step explanation:

* lets talk about the log

- If log a = b, that means the base of the log is 10

- To solve it we will change it to exponential function

∴ [tex]10^{b}=a[/tex]

* Now do that in each one of the problem

* ∵ f(x) = log x - 1

- To find the x-intercept put y = 0

∴ log x - 1 = 0 ⇒ add 1 to both sides

∴ log x = 1 ⇒ change it to exponential function

∴ [tex]10^{1}=x[/tex]

∴ x = 10

* The x-intercept = (10 , 0)

* ∵ f(x) = -(log x - 2)

- To find the x-intercept put y = 0

∴ -(log x - 2) = 0 ⇒ Multiply both sides by -1

∴ log x - 2 = 0 ⇒ add 2 to the both sides

∴ log x = 2 ⇒ change it to exponential function

∴ [tex]10^{2}=(x)[/tex]

∴ x = 100

* The x-intercept = (100 , 0)

* ∵ f(x) = log (-x - 2)

- To find the x-intercept put y = 0

∴ log (-x - 2) = 0 ⇒ change it to exponential function

∴ [tex]10^{0}=(-x-2)[/tex] ⇒ any number to the power of zero = 1 except 0

∴ -x - 2 = 1 ⇒ add 2 to the both sides

∴ -x = 3 ⇒ multiply both sides by -1

∴ x = -3

* The x-intercept = (-3 , 0)

* ∵ f(x) = -log -(x - 1)

- To find the x-intercept put y = 0

∴ -log -(x - 1) = 0 ⇒ multiply both sides by -1

∴ log -(x - 1) = 0 ⇒ change it to exponential function

∴ [tex]10^{0}=-(x-1)[/tex] ⇒ any number to the power of zero = 1 except 0

∴ -(x - 1) = 1 ⇒ multiply both sides by -1

∴ x - 1 = -1 ⇒ add 1 to both sides

∴ x = 0

* The x-intercept = (0 , 0)

Step-by-step explanation:

your answer is A 458.90.

The answer would be A)$458.90

Total students in the class who got the quiz = 28

The average of the class average was = 82.5

Five students that were absent made up the quiz after school and their scores were a 78, 89,92,99, & 63.

The formula for an average= (sum of values) / (count of values)

As the average is given as 82.5 and there were 28 students, so sum of the 28 values will be = [tex]28\times82.5=2310[/tex]

Total students of the class = 28+5(absent) = 33

For 33 students the total score was = 2310 +(78+89+92+99+63)

= 2731

So, average for 33 students will be = [tex]\frac{2731}{33} =82.757[/tex] or 82.76

So, the new class average is 82.76

Answer:

32.50 is the total cost, so you need to find the cost of each separate ticket.

First, you take the total, 32.50, and you divide it by the number of tickets, 5.

32.50/5

The answer is A.

Step-by-step explanation:

Final answer:

The correct equation that represents the cost of each ticket is A: x equals 32.50/5, which is obtained by dividing both sides of the original equation 5x = 32.50 by 5.

Explanation:

To determine the cost of each ticket that Nadia bought, we can use the given equation 5x = 32.50, where x represents the cost of each ticket. To solve for x, we need to isolate the variable on one side of the equation. This can be done by dividing both sides of the equation by 5, which leads us to x = 32.50 / 5. Therefore, the correct equation that represents the cost of each ticket is A: x equals 32.50/5.

Answer:

Circumference: 64π

Ratio:      1 : 4

Measure of ∠xoy:  π/2    

Step-by-step explanation:

We are given an arc length of 16π.  Since it's in terms of pi, we use the formula

S = rФ    where r is the radius, and Ф is the measure of the angle in radians (in terms of pi)

We are given S = 16π and r = 32, plug those in and find Ф

16π = 32Ф

  16π/32 = Ф

       π/2 = Ф

This is the measure of the central angle.  

The angle is π/2 radians.  There are 2π radians in the circumference, so the circumference is 4 times the arc length created by the central angle.  (There are 4 halves in 2)  so the ratio of the arc length tothe circumference is 1 : 4

The formula for circumference is C = 2πr, where r is the radius, so we hace

C = 2π(32) = 64π

The answer is

64

1/4

90

[tex]5\ years[/tex]  

Step-by-step explanation:

we know that

The  formula to calculate the depreciated value  is equal to  

[tex]D=P(1-r)^{t}[/tex]  

where  

D is the depreciated value  

P is the original value  

r is the rate of depreciation  in decimal  

t  is Number of Time Periods  

in this problem we have  

[tex]P=\$12,000\\r=9\%=0.09\\D=\$7,500[/tex]

substitute in the formula above and solve for t

[tex]\$7,500=\$12,000(1-0.09)^{t}[/tex]  

[tex](7,500/12,000)=(0.91)^{t}[/tex]  

Apply log both sides

[tex]log(7,500/12,000)=t*log(0.91)[/tex]  

[tex]t=log(7,500/12,000)/log(0.91)=5\ years[/tex]

The overall CGPA would be 2.90 so it is not possible for hum to secure a CGPA of 3 for graduation.

Answer:

75% of the original paper’s size.

Step-by-step explanation:

Let’s say that the original size was 10 inches.

You then increase it by 50%. It is now 15 inches.

Now, you decrease it by 50%. 50% of 15 is 7.5. So, the paper is now 7.5 inches.

7.5 inches is 75% of the original paper size.

Answer:

[tex]\large\boxed{Area:\ 69\ ft^2}\\\\\boxed{Perimeter:\ 58\ ft}[/tex]

Step-by-step explanation:

Look at the picture.

The perimeter:

[tex]P=3+17+12+2+9+15=58\ ft[/tex]

We have two rectangles 12 ft × 2 ft and 15 ft × 3 ft.

Calculate the areas of the rectangles:

[tex]A_1=(12)(2)=24\ ft^2\\\\A_2=(15)(3)=45\ ft^2[/tex]

The area of the figure:

[tex]A=A_1+A_2\\\\A=24+45=69\ ft^2[/tex]

Answer:

Fourth option

Step-by-step explanation:

When graphing the given inequalities you will get a region like the one shown in the attached image. This region is delimited by 4 straight

[tex]x = 0\\\\y = 0\\\\9x + 6y = 400\\\\7x + 10y = 400[/tex]

The points indicated at the ends of the region are the maximum possible values of x and y.

We must test these points in the objective function [tex]P = 2x + 2.5y[/tex] and see which point maximizes the value of P.

Remember that the boundaries of the region are not included.

We can prove the point x = 0 and y = 39 because (0,4) is not included in the region.

[tex]P = 2(0) + 2.5(39) = 97.5[/tex]

Now we test the point x = 33 and y = 16

[tex]P = 2(33) + 2.5(16) = 106[/tex]

Now we test the point x = 44 and y = 0

[tex]P = 2(44) + 2.5(0) = 88[/tex]

Finally the optimal value is:

x = 33 oz

y = 16 oz

With a gain of $106

0.0006=6x10^-4

Since the exponent is negative, the number will get smaller. A negative exponent shows that the decimal point is shifted that number of places to the left. The exponent is -4, so the decimal place will move 4 places to the left.

Answer:

0.0006

Step-by-step explanation:

A number in scientific notation if it has the form a × 10ⁿ.

A negative exponent indicates

6 × 10⁻⁴ tells you that the decimal number is 6. with the decimal point moved four places to the left.

Thus, 6 × 10⁻⁴ becomes 0.0006

[tex]\large\boxed{(3x-8)+(2x+5)-(4x-8)=x+5}[/tex]

Step-by-step explanation:

[tex](3x-8)+(2x+5)-(4x-8)\\\\=3x-8+2x+5-4x-(-8)\\\\=3x-8+2x+5-4x+8\qquad\text{combine like terms}\\\\=(3x+2x-4x)+(-8+5+8)\\\\=x+5[/tex]

To simplify the expression (3x-8)+(2x+5)-(4x-8), distribute the negative sign, combine like terms, and simplify to x+5.

To simplify the expression (3x-8)+(2x+5)-(4x-8), we need to combine like terms. Start by distributing the negative sign in front of the parentheses that contain (4x-8):

(3x-8)+(2x+5)-4x+8

Now, combine the like terms:

3x+2x-4x-8+5+8

Combine similar terms:

1x+5

So, the simplified expression is x+5.
