The area of the plate is 7850 square millimeters.

Important information:

Circumference of a circle with radius [tex]r[/tex] is:

[tex]C=2\pi r[/tex]

[tex]100\pi=2\pi r[/tex]

[tex]\dfrac{100\pi}{2\pi}=r[/tex]

[tex]50=r[/tex]

The radius of the plate is 50 millimeters.

Now, the area of the plate is:

[tex]A=\pi r^2[/tex]

[tex]A=(3.14)(50)^2[/tex]

[tex]A=(3.14)(2500)[/tex]

[tex]A=7850[/tex]

Therefore, the area of the plate is 7850 square millimeters.

Answer:

Step-by-step explanation:

We would apply the formula for determining the volume of a square based pyramid which is expressed as

Volume = 1/3 × base area × height

From the information given,

Side length = 230m

Height = 145m

Since the base is a square,

Base area = 230² = 52900

Therefore,

Volume = 1/3 × 52900 × 145

Volume = 2556833.3 cubic meters

The amount of stone needed is expressed in volume.

Answer: C, 224 inches squared

Step-by-step explanation:

When formed into a solid, the triangles are folded upwards to make a pyramid. You can find the surface area by finding the areas of the individual shapes.

There are four triangles with a height of 10 inches and a base of 8 inches.

There is one square with a side length of 8 inches.

Triangle area formula : A = (b * h) / 2

Square area formula: A = s^2

(10 * 8) / 2 = 40

8 ^ 2 = 64

There are four triangles with area of 40 and one square with area of 64.

40 + 40 + 40 + 40 + 64 = 224 inches squared. The correct answer choice is C.

The surface area of the pyramid is 224 in².

The surface area of a solid object is a measure of the total area that the surface of the object occupies.

Given net will form a square pyramid, so we will find the surface area of the square pyramid.

Therefore,

The area of the pyramid = side² + 2 × side × height

= 8² + 2 × 8 × 10

= 64 + 160

= 224

Hence the surface area of the pyramid is 224 in².

Answer:

x = 135,

y = 45

Step-by-step explanation:

45 and y are vertical angles.  That means they are equal

y = 45

45 and x form a straight line which means they sum to 180

45+x = 180

Subtract 45 from each side

45+x-45 =180-45

x = 135

Answer:

Number of miles = dependent variable

Number of gallons used = independent variable

Step-by-step explanation:

In order for the driver to see how many miles the car can run, they must first see how many gallons of gas they have in the car. The number of miles depend on the number of gallons used. So, your answer would be letter choice A.

The statement which best represents the relationship is that, the number of miles is the dependent quantity and the number of gallons is the independent quantity.

Dependent variable are variables which depends on another variable to take it's value.

Independent variables are those which does not depend on other variables.

Given is a table which represents the number of miles travelled and the number of gallons of gas used.

From the table, if x represents the number of gallons of gas used and y represents the number of miles travelled, then the equation can be written as,

y = 35x

It is clear that, the value of y depends on the value of x.

So, x is the independent variable and y is the dependent variable.

That is, number of gallons of gas used is the independent variable and number of miles travelled is the dependent variable.

Hence the number of miles is the dependent quantity and the number of gallons is the independent quantity.

Answer:

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

Step-by-step explanation:

this is because to be able to find the perimeter you use the formula 2(l) + 2(w)

The expression for the perimeter of the rectangle is 10x + 2.

Given the sides of the rectangle:

Length = 3x+4

Width = 2x-3

To determine the expression for the perimeter of the rectangle, we need to consider that the perimeter of a rectangle is given by the sum of all its sides.

The expression for the perimeter (P) is calculated as follows:

Perimeter = 2(Length + Width)

Plug these values into the perimeter formula:

P = 2(3x+4 + 2x-3)

Now, let's simplify the expression:

P = 2(5x + 1)

Finally, we can further simplify it:

P = 10x + 2

Therefore, the perimeter is 10x + 2.

Answer:

51 feet

Step-by-step explanation:

To find how many feet will Natalie run, we just need to sum the four sides of the park that she will run:

Total distance = 15 + 10 + 12 + 14 = 51 feet

So if Natalie runs the sides of the park, she will run a total of 51 feet.

This value is also the perimeter of the park, that is, the sum of all 4 sides of the park.

(C)x=11.6, y=23.2

Step-by-step explanation:

Using Theorem of Intersecting Secant and Tangent

Applying this theorem in the diagram, we have:

[tex]TQ$ X TP=TR^2[/tex]

[tex]10(10+x+4)=16^2\\10(14+x)=256\\140+10x=256\\10x=256-140\\10x=116\\$Divide both sides by 10\\x=11.6[/tex]

Next, we apply Theorem of Intersecting Chords

PV X VQ=SV X VR

4 X x= 2 X y

Recall earlier we got: x=11.6

2y=4 X 11.6

2y=46.4

Divide both sides by 2

y=46.4/2=23.2

Therefore: x=11.6, y=23.2
