Answer:

The area of the shaded sector is [tex]51.2\pi \ units^{2}[/tex]

Step-by-step explanation:

I assume that the problem is

Find the area of the shaded sector of the circle with radius equal to 16 units

step 1

Find the value of x

we know that

[tex]8x+2x=360\°[/tex]-----> by complete circle

[tex]10x=360\°[/tex]

[tex]x=36\°[/tex]

The central angle of the shaded sector is 2x

[tex]2(36\°)=72\°[/tex]

step 2

Find the area of the circle

The area of the circle is equal to

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

we have

[tex]r=16\ units[/tex]

substitute

[tex]A=\pi (16)^{2}[/tex]

[tex]A=256\pi\ units^{2}[/tex]

step 3

Find the area of the shaded sector

we know that

A central angle of 360 degrees subtends an area of circle equal to [tex]256\pi\ units^{2}[/tex]

so

by proportion

Find the area of the shaded sector by a central angle of 72 degrees

[tex]\frac{256\pi}{360}=\frac{x}{72} \\ \\ x=256\pi *(72)/360\\ \\x=51.2\pi \ units^{2}[/tex]

To solve the problem, set up two equations: X + Y = 12 and X = 2Y. Using the substitution method, replace X with 2Y in the first equation to find Y = 4, and subsequently find X = 8.

The problem given to us involves finding two numbers, X and Y, given that the sum of these two numbers is 12 and the first number, X, is twice the second number, Y. To solve for X and Y, we can set up a system of two linear equations.

The first equation comes from the sum of the two numbers:

X + Y = 12

The second equation comes from the statement that X is twice Y:

X = 2Y

Now we have a system of equations:

One method to find solutions for X and Y is by substitution. We can substitute 2Y in place of X in the first equation:

Now that we know Y is 4, we can find X using the second equation:

The two numbers are X = 8 and Y = 4.

Step-by-step explanation:

The formula of a volume of a cube:

V = s³

s - side length

We have s = 1/4 ft. Substitute:

V = (1/4)³ = 1/64 ft³

We have four cubes.

4V = 4 · 1/64 = 1/16 ft³

5x + 2y + z

Step-by-step explanation:

The perimeter of a polygon is the sum of the lengths of all the sides of the polygon. This polygons has 8 sides. Their lengths are:

x, x, x, x, x, y, y, z

The perimeter of the polygon is the sum of the lengths shown above.

perimeter = x + x + x + x + x + y + y + z

The expression above can be simplified by combining like terms.

perimeter = 5x + 2y + z

Answer: C

Since all the answers have (-6), it means that you multiply the whole equation on both sides by 6, which makes a (2/3)x become a 4x and a (1/2) become 3

Answer:

C

Step-by-step explanation:

Start by multiplying through by 3. That is the first of 2 possible steps.

3[2/3 x - 1  = 1/2]

2x - 3 = 3/2              

Now multiply by 2

2 [ 2x - 3 = 3/2]

4x - 6 = 3

That makes C the only possible answer.

oop I didn't realize this was in 2019:-:

For this case we must solve the following inequality:

[tex]x-2> 2x + 12[/tex]

We follow the steps below:

We subtract 2x on both sides of the inequality:

[tex]x-2-2x> 2x + 12-2x\\-x-2> 12[/tex]

We add 2 to both sides of the inequality:

[tex]-x> 14[/tex]

We multiply by -1 on both sides of the inequality, taking into account that the sense of inequality changes:

[tex]x <14[/tex]

Answer:

[tex]x <14[/tex]

Answer:

The guys above is wrong because it should be x < -14 because you have to balance out both sides of the equation, you can't just do something to one side of the equation and not do it to the other.

Answer:

It makes sense for the answer to be 86 degrees since it's almost a right angle.

Answer:

The correct answer is option C.   86°

Step-by-step explanation:

From the figure we can see a circle.

To find the measure of <PRQ

Consider the triangle PQR,

<PRQ  = <PTR + <RPT

From the figure we get,

<PTR = 102/2 = 51

<RPT = 70/2 = 35

<PRQ  = <PTR + <RPT

51 + 35 = 86°

Therefore the correct answer is option C.   86°

____________________________________________________

Answer:

Your answer would be C). y = 100 - 5x

____________________________________________________

Step-by-step explanation:

Let's break down the question so it would be more easier to figure out the answer.

We would be making a y = mx + b equation

Important information:

With the information above, we can use that to make our equations.

We know that the place has a 100 gallon fish tank. in the question, it says that for the equation, the tank was full, so that would be our "beginning point" or "starting value. From the equation, it would represent our "B" value.

Our equation should look like this now:

y = mx + 100

Now we need to find the rate of change.

In the question, it says that the tank DRAINS at around 5 gallons per minute, meaning that we would have to subtract 5 (-5). That would represent your "m" value on the equation. Your equations should now look like this:

y = -5x + 100

F.Y.I: y = 100 - 5x is the same that as -5x + 100, it's just flipped, and y = 100 - 5x is the answer choice that looks close to the one we made.

Answer choice C). y = 100 - 5x would be your FINAL answer.

____________________________________________________

The equation that describes the situation where a 100-gallon tank is drained at a rate of 5 gallons per minute is y = 100 - 5x. This because each minute, the volume decreases by 5 gallons from the starting amount of 100 gallons.

The question is about how to represent a process which decreases at a constant rate in terms of mathematical expression. In this case, Patti's Pet Palace is draining a 100-gallon fish tank at a rate of 5 gallons per minute. The total amount of water in the tank decreases as time progresses and the tank drains.

This process can be represented using a negative slope linear equation. If y represents the amount of water in the tank after x minutes, the initial amount is 100 gallons and it decreases by 5 gallons each minute.

Therefore, the equation to represent this process is y = 100 - 5x. That means option C is the correct answer. For each minute that passes (represented as 'x'), 5 gallons are subtracted from the initial 100 gallons.

Answer:

From the information, we know that the plate will hold 3 pieces of sushi, each with a diameter of 1 1/2 inches, and there be 1/2 inch space from the edge of the of the suchi to the edge of the plate.

The diamter of the suchi plates we need to puchase should be the sum of the diameter of the sushi and the the space between them and the edge of the plate:

  (3 . 1 1/2) + (2 . 1/2)

= (3 . 3/2) + 1

= 9/2 + 1

= 9/2 + 2/2

= 11/2 = 5.5 (inches)

Answer:

From the information, we know that the plate will hold 3 pieces of sushi, each with a diameter of 1 1/2 inches, and there be 1/2 inch space from the edge of the of the suchi to the edge of the plate.

The diamter of the suchi plates we need to puchase should be the sum of the diameter of the sushi and the the space between them and the edge of the plate:

  (3 . 1 1/2) + (2 . 1/2)

Part a) The total length of the circular portions is [tex]12\pi\ in[/tex]

Part b) The total length of wire needed is tex]53.7\ in[/tex]

Part c) The total weight of the ornament is [tex]97\ g[/tex]

Step-by-step explanation:

Part a) Find the total length of the circular portions in terms of pi

we know that

The diameter of the circle is equal to the length side of the square

[tex]D=4\ in[/tex]

The total length of the circular portions is equal to the circumference of three complete circle

Because each circular portion is equal to 3/4 of circle

so

[tex](3/4)*4=3[/tex]

The circumference of four three quarter circles is equal to

[tex]C=3(\pi D)[/tex]

substitute the diameter

[tex]C=3(\pi (4))[/tex]

[tex]C=12\pi\ in[/tex]

Part b) Find the total length of wire needed

The total length of the circular portions is [tex]12\pi\ in[/tex]

assume

[tex]\pi =3.14[/tex]

[tex]12(3.14)=37.68\ in[/tex]

The total length of the square portion is equal to

[tex]4b=4(4)=16\ in[/tex] -----> perimeter of a square

Adds the lengths

[tex]37.68+16=53.68\ in[/tex]

Round to the nearest tenth

[tex]53.68=53.7\ in[/tex]

Part c) Find the total weight of the ornament

we know that the ornament weights 1.8 grams per inch

so

Multiply the total length by 1.8 to obtain the total weight

[tex]53.7(1.8)=96.66\ g[/tex]

Round to the nearest gram

[tex]96.66=97\ g[/tex]

(20+2)(10+9)

Step-by-step explanation:

The area model is written as (a+b)(c+d). To write a multiplication problem into an area model, split it into numbers which add to it. Multiples of 10 are most commonly used.

For example 22*19 becomes (20+2)(10+9).

Answer: The answer is 12.6 Meters Squared

You get that from multiplying 120 to 3.5 and 2.5 . After doing that you will get 420 cm and 300 cm. Knowing that a meter is 100 cm you will get 4.2 meters and 3 meters. To find the area of the kitchen space you will multiple 4.2 and 3 meters together and get 12.6 Meters, therefore 12.6 meters squared is the area of the kitchen floor.
