Triangular pyramids contain four sides, six edges, and four vertices.

What is a pyramid?

A pyramid is a structure with triangular exterior surfaces that converge to a single step at the summit, giving the form the shape of a pyramid in the geometric sense. A pyramid's base can be cooperation agreement, quadrilateral, or any polygon form. As a result, a pyramid has at least three triangular surfaces on its outside (at least four faces including the base). A typical alternative is the squares pyramid, which has a square shape and four triangular exterior surfaces. The design of a pyramid, with the majority of the weight closer to the bottom and the select at the apex, means that less material will be pushed from above. This center of mass enabled early civilizations to build sturdy massive constructions.

Answer: About 1 to 1.5 ratio. You would use one cup rice to 1.5 cup water.

Step-by-step explanation:

The given equations, 2x + y = -3 and -2y = 6 + 4x, written in slope-intercept form is y = -2x - 3

From the question, we are to write the equations in slope-intercept form.

The given equations are

2x + y = -3

and

-2y = 6 + 4x

The slope-intercept form of the equation of a line is

y = mx + b

Where m is the slope

and b is the y-intercept

Writing 2x + y = -3 in slope-intercept form

2x + y = -3

Subtract 2x from both sides of the equation

2x - 2x + y = -3 - 2x

y = -3 - 2x

y = -2x - 3

Writing -2y = 6 + 4x in slope-intercept form

-2y = 6 + 4x

Divide through by -2

-2y/-2 = 6/-2 + 4x/-2

y = -3 - 2x

y = -2x - 3

Hence, the equation is y = -2x -3

Answer:

-8 < x ≤ 0

Let's remember what open and closed circle mean:

Open Circle:

Less than ( < ) / Greater than ( > )

Closed Circle:

Greater than or equal to ( ≥ ) / Less than or equal to ( ≤ )

Now, let's review this graph:

Let's call this unknown value 'x'

Reading the graph left to right:

x is greater than -8, but is less than or equal to (Remember!! Closed circle!)

We can right this as:

-8 < x ≤ 0

And that is our answer! If your problem wants a different variable (y, z, q, etc) just put that in place of 'x'

Let me know if this helped!

Put different values of x in the function and find values of g(x). Then plot the points on a graph.

Graphing a function involves tracing the curve on a coordinate plane that corresponds to the function. Every point on the curve will satisfy the function equation if the curve (or graph) reflects the function.

The given function is

g(x) = - 3x

Put x = - 3

g(x) = -3(-3)

g(x) = 9

Put x = - 2

g(x) = -3 (-2)

g(x) = 6

Put x = - 1

g(x) = -3 (-1)

g(x) = 3

Put x = 1

g(x) = - 3 (1)

g(x) = - 3

Put x = 2

g(x) = -3 (2)

g(x) = - 6

Plot the points on a graph, and keep the values of x on the x-axis and g(x) on the y-axis.

Answer:

365

Step-by-step explanation:

As the amount of fish the emporium sold and received are the same, the inventory of fish has not changed.  Therefore, the emporium has 365 fish at the end of the day on Tuesday.

Monday morning:  365 fish

After Monday's sales:  365 - 15 = 350 fish

Tuesday morning:  350 fish

After Tuesday's shipment:  350 + 15 = 365 fish

Answer:

End of Tuesday = 365 fishes

Step-by-step explanation:

Fishes in inventory,

→ n = 365 fishes

Let's take it as,

→ Monday (x) = 15

→ Tuesday (y) = 15

Forming the expression,

→ (n - x) + y

Let's solve the expression,

→ (n - x) + y

→ (365 - 15) + 15

→ 350 + 15

→ 365 fishes

Hence, there are 365 fishes.

step by step explanation: you literally add them up

The rate of Sam in miles per hour is 10.13.

Based on the relation between the units feet and mile, firstly converting the distance in miles.

5380 feet = 1 mile

So, 63,756 feet = 63,756 ÷ 5380

Performing division to calculate the distance in miles

63, 756 feet = 11.85 miles

Now converting the time in hour. As per the known fact, 60 minutes = 1 hour

So, 70 minutes = 70÷60

70 minutes = 1.17 hours

Now, finding the rate in miles per hour = number of miles ÷ amount of time

Rate in miles per hour = 11.85 ÷ 1.17

Performing division on Right Hand Side of the equation

Rate in miles per hour = 10.13

Thus, the rate is 10.13 miles per hour.

im not sure what her age is in seconds with scientific notation though sorry :(

The value of trigonometric function sin(x-y) = -44/125

Given ,

cos x = 3/5

sin y = 24/25

Sin( x - y) = sin(x)cos(y) - sin(y)cos(x)

substituting the values,

=> sin(x)cos(y) - sin(y)cos(x)

=> sin(x)cos(y) - (24/25)(3/5) ------(1)

As we know ,

sin(x) = √(1 - cos²x)

sin x = √(1 - (3/5)²)

=> sin x = √1 -9/25

=> sin x = √16/25

=> sin x = 4/5

Again ,

cos y = √(1 - sin²y)

=> cos y = √(1 - (24/25)²

=> cos y = √1 - 576/625

=> cos y = √49/625

=> cos y = 7/25

Substituting the values of sin x and cos y in equation (1)

=> sin(x - y) = (4/5)(7/25) - (24/25)(3/5)

=>  sin(x - y) = (28 / 125) - (72 / 125)

=>  sin(x - y) = -44/125

The total price of 3 pencils and 1 protractor at $3 was 4 times the total price of 1 pencil and 1 eraser at $0.60. What is the price of 1 pencil?​

when pencil = p

3p + 3 = 4(p + 0.6)

expand right side:

3p + 3 = 4p + 2.4

subtract 3 from both sides:

3p + 3 - 3 = 4p + 2.4 - 3

3p = 4p -0.6

subtract 4p from both sides:

3p - 4p = 4p -0.6 - 4p

-p = -0.6

divide both sides by -1:

(-p)/-1 = (-0.6)/-1

p = 0.6

so each pencil costs $0.60

The type of function that represents the bank account as a function of time is: this is an exponential function because there is a common ratio in the balance between the months.

In order to determine the type of function that models or represents the bank account as a function of time, we would check whether or not there is a common difference or common ratio.

In Mathematics, a linear function is used to model a situation when there exist a constant or common difference between its consecutive terms. On the other hand, an exponential function there is used to model a situation when there exist a constant or common ratio between its consecutive terms.

For the common difference, we have:

d = 1,474.56 - 1,843.20 = -368.64

d = 1,843.20 - 2,304.00 = -460.8

Therefore, the bank account as a function of time is not a linear function.

For the common ratio, we have:

r = 1,474.56/1,843.20 = 0.8

r = 1,843.20/2,304.00 = 0.8

Therefore, the bank account as a function of time is an exponential function.

Step-by-step explanation:

The value of n for the given exponential function is 5/2.

Exponential function:

Exponential function means the function in the form f (x) = aˣ, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0.

Given,

Here we have the exponential function (√7)⁵ = 7ⁿ

Now, we need to find the value of n.

Based on the rule of exponent, we have written the square as 1/2, like the following,

√7 = [tex]7^{\frac{1}{2}}[/tex]

So, when we apply these on the given expression then we get,

(√7)⁵ = [tex](7^{\frac{1}{2}})^5[/tex]

Now, we have to multiply both values on the power then we get,

=> [tex](7^{\frac{5}{2}})[/tex]

When we equate this with the RHS, then we get the value of n as,

From the question, we have the following equation that can be used in our computation:

p(n)=2n

To make the equation legible, we need to rewrite it

So, we have the following representation

p(n) = 2n

Also from the question, we have

p(-1)

This means that the value of n is -1, and we calculate p(n) when n = -1

Substitute the known values in the above equation, so, we have the following representation

p(-1) =  2 * -1

So, we have the following equation

p(-1) =  2 * -1

There is no constant to add or subtract to both sides of the equation

Mean refers the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers.

Given,

Here we have the table of data.

Now, we need to estimate for the mean time some people spent mowing their lawn.

According to the given problem, the mean is calculated for each time interval, then we get,

For the time period 0 ≤ t < 10, then the mean is,

=> 3/(3 + 11 + 14 + 2)

=> 3/30

=> 0.1

For the time period 10 ≤ t < 20, then the mean is,

=> 11/(3 + 11 + 14 + 2)

=> 11/30

=> 0.37

For the time period 20 ≤ t < 40, then the mean is,

=> 14/(3 + 11 + 14 + 2)

=> 14/30

=> 0.47

For the time period 40 ≤ t < 60, then the mean is,

=> 2/(3 + 11 + 14 + 2)

=> 2/30

Step-by-step explanation:

The congruence statement that says:

△CAT ≅ △DOG,

says not only that the triangles are the same shape and size, it also says //which// angles (and sides) are conguent.

Angle C and Angle D are the same. Angle A and Angle O are the same. And Angle T and Angle G are the same.

So in △CAT, Angle C is 25° and Angle A (same as O) is 37°.

Also, all the angles in a triangle add up to 180°.

25° + 37° + T = 180°

62° + T = 180°

T = 118°

And T corresponds to G, so AngleG is also 118°.
