The length of each side of the base of the pyramid is 14 cm

From the question, we are to determine the length of each side of the base of the pyramid

The volume of a square-based pyramid is given by

V = 1/3(b²h)

Where V is the volume

b is the length of the base

and h is the height

From the given information,

V = 392 cm³

h = 6 cm

Putting the parameters into the equation, we get

392 = 1/3(b²× 6)

392 = b² ×2

b² = 392/2

b² = 196

b = √196

b = 14 cm

Hence, the length of each side of the base of the pyramid is 14 cm

Part 1

By the inscribed angle theorem, arc PA measures 62 degrees.

Part 2

Angles inscribed in the same arc are congruent, so angle PRA measures 31 degrees.

Part 3

Diameters form semicircles, and the arc of a semicircle measures 180 degrees, so arc PAR measures 180 degrees.

Part 4

Subtracting arc PA from arc PAR, we get arc AR measures 118 degrees.

Answer:

Hence, 0.0000087 can be expressed as [tex]$8.71 \times 10^{-6}$[/tex].

Step-by-step explanation:

- Given 0.00000871

- Move the decimal point so that the factor is greater than or equal to 1 but less than 10 .

- Then count n and write no. as product with a power of 10 .

Step 1 of 1

Consider 0.00000871,

8.71

Decimal has moved 6 places to right.

The power will be negative as the original no. is less than 1 .

[tex]$$\begin{array}{r}8.71 \times 10^{-6} \\0.0000087=8.71 \times 10^{-6}\end{array}$$[/tex]

The solution to the given product is:

-6i*(6 - 2i) = -12 - 36i

Here we want to solve:

-6i*(6 - 2i)

Here the thing that you need to remember is that i² = -1.

Expanding the product, we get:

-6i*(6 - 2i) = (-6i)*6  + (-6i)*(-2i)

               = -36i + (6i)*(2i) = -36i + 12i² = -36i - 12

Then we conclude:

Answer:

Step-by-step explanation:

we can find the area of a trapezoid from its bases and height in the following formula:

[tex]A=\frac{a + b}{2}h[/tex]

where...

A: area

a: one base

b: other base

h: height

here, we can see that our two bases are 9 and 17, and that our height is 8.

Now, let's plug these values into our formula:

a: 9

b: 17

h: 8

[tex]A=\frac{a + b}{2}h[/tex]

[tex]A=\frac{9 + 17}{2}8[/tex]

Now, we can simplify:

[tex]A=\frac{9 + 17}{2}8[/tex]

[tex]A=\frac{26}{2}8[/tex]

A = 13 · 8

A = 104

so, the area of this trapezoid is 104m²

(note: we write area as squared / in square units)

The maximum value of allowable emissions in the year 2031 is equal to 3,502.

In order to determine the maximum value of allowable emissions in the year 2031, we would use an exponential function which also relates to compound interest as follows:

A = P(1 - r)^t

For the time, we have:

Time, t = 2031 - 2022

Time, t = 9

Substituting the given parameters into the formula, we have;

A = 4,200(1 - 0.02)^9

A = 4,200(0.98)^9

A = 4,200 × 0.8338

The value of the given algebraic expression is -63/8.

To evaluate an algebraic expression, we substitute the values of the variables in the expression, and then follow the rules of solving a numeral expression.

In the question, we are asked to evaluate the algebraic expression:

{(3a - b)/2c} + {(3a - c)/(c - b)}, given the values of a = 3, b = -2, and c = -4.

To evaluate the expression {(3a - b)/2c} + {(3a - c)/(c - b)}, given the values a = 3, b = -2, and c = -4, we substitute these values in the expression and solve as follows:

{(3(3) - (-2))/2(-4)} + {(3(3) - (-4))/((-4) - (-2))}

= {(9 + 2)/(-8)} + {(9 + 4)/(-4 + 2)}

= {-(11/8)} + {-(13)(2)}

= -(11/8) - (13/2)

= -(11/8) - (52/8)

= -(63/8).

Thus, the value of the given algebraic expression is -63/8.

Answer:

(b) 25 muffins

(c) 38 muffins

Step-by-step explanation:

Given:

Forming system of linear equations:

muffins (m) + cookies (c) = 200 treats

1.60m + 0.80c = $200

Solve by Substitution:

m + c = 200

1.6m + 0.8c = 200

using m + c = 200, solve for m by subtracting c:

m + c - c = 200 - c

m = 200 - c

we can now plug in m tot he second equation,

1.6(200 - c) + 0.8c = 200

320 - 0.8c = 200

320 - 320 - 0.8c = 200 - 320

-0.8c = -120

-0.8c/-0.8 = -120/-0.8

c = 150

plug c back in to find m,

m = 200 - c

m = 200 - 150

m = 50

(b) if you buy 200 cookies, then how many muffins?

we use this equation as we want to stay in the price limit: 1.6m + 0.8c = 200

c = 200 so 1.6m + 0.8(200) = 200

1.6m + 0.8(200) = 200

1.6m + 160 = 200

1.6m = 200 - 160

1.6m = 40

1.6m/1.6 = 40/1.6

Step-by-step explanation:

The sum of the probabilities of all possible outcomes is 1.

As the die is loaded so that the number 4 occurs 3/10 of the time, and the other numbers occur with equal frequency, then the probability of numbers 1, 2, 3, 5, 6, 7 and 8 being rolled is 1/10.

Create a probability distribution table for X, where X is the score on the loaded 8-sided die:

[tex]\begin{array}{ | c | c | c | c | c | c | c | c | c |}\cline{1-9}x & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 \\\cline{1-9} & & & & & & & &\\ \text{P}(X=x) & \dfrac{1}{10} & \dfrac{1}{10} & \dfrac{1}{10} & \dfrac{3}{10} & \dfrac{1}{10} & \dfrac{1}{10} & \dfrac{1}{10} & \dfrac{1}{10}\\& & & & & & & &\\\cline{1-9}\end{array}[/tex]

Add a product row and a totals column:

[tex]\begin{array}{ | c | c | c | c | c | c | c | c | c | c |}\cline{1-10}x & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 &\text{Total} \\ \cline{1-10} &&&&&&&&& \\ \text{P}(X=x) & \frac{1}{10} & \frac{1}{10} & \frac{1}{10} & \frac{3}{10} & \frac{1}{10} & \frac{1}{10} & \frac{1}{10} & \frac{1}{10} & 1\\ &&&&&&&&&\\ \cline{1-10} &&&&&&&&&\\\text{Product} & \frac{1}{10} & \frac{2}{10} & \frac{3}{10} & \frac{12}{10} & \frac{5}{10} & \frac{6}{10} & \frac{7}{10} & \frac{8}{10} & \frac{44}{10} \\ &&&&&&&&&\\\cline{1-10}\end{array}[/tex]

(The Product is row is the product of the score on the die and its probability).

The expected value (EV) is the sum of the product of each outcome and its probability.  

Therefore, the expected value (EV) of this die is 44/10 = 4.4
