In the figure below, OMPN is a square. If the area of the circle O is 4π then what is the area of the shaded region?

Answer:

A’/A = 2.25

Step-by-step explanation:

Let the length and width of ABCD be l and w respectively.

A = lw

=====

For rectangle A’B’C’D’  

l’ = 1.5l and w’ = 1.5w

A’ = l’w’

A’ = 1.5l × 1.5 w

A’ = 2.25 lw

=====

A’/A = 2.25lw/(lw)     Cancel lw

A’/A = 2.25

The area of the dilated rectangle is 2.25 times that of the original.

Answer:

c = 1/7

Step-by-step explanation:

Here we have to solve the linear equation.

We need to find the value of c.

5 = 6 - 7c

Isolate the variable and constants

Add 7c on both sides, we get

7c + 5 = 6 - 7c + 7c

7c + 5 = 6

Subtract 5 from both sides, we get

7c + 5 - 5 = 6 - 5

7c = 1

Dividing both sides by 7, we get

c = 1/7

Answer:

The equation in point - slope form of a line that passes through the points (3,-5) and (-8,4) is: y-(-5) = -(9/11) (x-3) or y+5 = -(9/11) (x-3)

Step-by-step explanation:

P1=(3,-5)=(x1,y1)→x1=3, y1=-5

P2=(-8,4)=(x2,y2)→x2=-8, y2=4

Equation in Point-Slope Form: y-y1=m(x-x1)

Slope: m=(y2-y1)/(x2-x1)

Replacing the known values:

m=[4-(-5)] / (-8-3)

m=(4+5) / (-11)

m=(9) / (-11)

m=-(9/11)

Equation in the point - slope form:

y-(-5) = -(9/11) (x-3)

y+5 = -(9/11) (x-3)

Answer:

The length of CX is 22 ft.

Step-by-step explanation:

Given information: In triangle ABC, F, G, and H are the midpoints of sides BC, CA, and AB respectively.

The medians FA, BG and CH intersect each other at point X.

According to the property of triangle, the intersection point of medians is called centroid and the centroid divides each median in 2:1.

Since X is centroid, therefore points X divides the median CH in 2:1, therefore we can say that CX:XH is 2:1.

It is given that the length of CX is 33.

[tex]CX=\frac{2}{3}CH[/tex]

[tex]CX=\frac{2}{3}\times 33[/tex]

[tex]CX=2\times 11[/tex]

[tex]CX=22[/tex]

Therefore the length of CX is 22 ft.

Step-by-step explanation:

Answer:

X = 17°

Step-by-step explanation:

Given that triangle Δ IJK ≅ triangle Δ PQR.

Using CPCTC (corresponding parts of congruent triangles are congruent), we can say angle ∠I = angle ∠P.

given angle ∠I = 3x + 4, and angle ∠P = 72 - x.

Now solving angle ∠I = angle ∠P.

3x + 4 = 72 - x

3x = 72 - x - 4

3x = 68 - x

3x + x = 68

4x = 68

x = 68/4 = 17 degrees.

Hence, the value of x is 17°.

If all sides have the same length, then this is an equilateral triangle. Therefore, the measures of the angles are the same and amount to 60°.

Therefore we have the equations:

7x - 3 = 60    add 3 to both sides

7x = 63      divide both sides by 7

x = 9

----------------

11y + 5 = 60        subtract 5 from both sides

11y = 55     divide both sides by 11

y = 5

Check:

m∠N = (7x - 3)° → m∠N = (7(9) - 3)° = (63 - 3)° = 60°

m∠M = (11y + 5)° → m∠M = (11(5) + 5)° = (55 + 5)° = 60°

We have answered a three-part mathematical question. First, we converted 35% to a fraction, resulting in 7/20. We then calculated the sale price of inline skates by deducting this percentage from the original price to reach $81.24. Finally, we computed a 5% tax on the sales price to find a final total cost of $85.3.

This question moves through several concepts in percentage and tax calculation. The first part of the question asks you to express 35% as a fraction, which, when reduced, can be represented as 7/20.

For the second part of the question, in order to calculate the sale price, we need to compute 35% ($43.75) of the original price ($124.99) and deduct this amount from the original price, resulting in a sale price of $81.24.

Lastly, we need to calculate and add a 5% sales tax to the sale price. 5% of $81.24 is $4.06. Adding this to the sale price, we get a total cost of $85.3.

Answer:

x=1, y=4

Step-by-step explanation:

5x+y=9

10x-7y=-18

To solve by elimination, we pick a variable to eliminate, or get rid of.  I will multiply the first equation by -2 so we can get rid of x

-2( 5x+y)=9 *-2

-10x -2y = -18

Now we add this equation to the second equation

-10x -2y = -18

10x-7y=-18

-------------------------

-9y = -36

Divide each side by -9

-9y/-9 = -36/-9

y =4

We still need to solve for x

5x+y=9

Put in y=4

5x+4 = 9

Subtract 4 from each side

5x +4-4 = 9-4

5x = 5

Divide each side by 5

5x/5 = 5/5

The Difference between expressions '8 less than q' and 'ans' is q - ans - 8.

The phrase '8 less than q' can be expressed as q - 8.

To find the difference between q - 8 and the answer 'ans', you subtract the two expressions: (q - 8) - ans.

This simplifies to q - 8 - ans, or q - ans - 8.

For example, if q = 15 and ans = 5, the difference would be 15 - 5 - 8, which equals 2.

So the difference between '8 less than q' and 'ans' is q - ans - 8.

Correct answer is B.14

When 18 is divided by 4, the quotient is 4 and the remainder is 2.

The division of 18 by 4, can be performed using long division or mental math. First, understand that 'dividend' is the number being divided (18), 'divisor' is what you divide by (4), 'quotient' is the result of the division and 'remainder' is what is left over.

Step 1: Divide 18 by 4. 4 fits into 18 four times (4 x 4 = 16).

Step 2: Subtract the 16 from 18 to find the remainder. 18 - 16 equals 2.

So, the quotient of 18 divided by 4 is 4 and the remainder is 2.

Answer: The value of x = 16 units, y = 4.5 units and z = 7.5 units.

Step-by-step explanation:

Since we have given that

ABCD and EFGH are two similar polygons.

Dimensions of ABCD are as follows :

AB = 6 units

BC = 8 units

AD = x units

CD = 10 units

Dimensions of EFGH are as follows :

EF = y

FG = 6 units

EH = 12 units

GH = z

Since they are similar:

[tex]\dfrac{AB}{EF}=\dfrac{BC}{FG}=\dfrac{CD}{GH}=\dfrac{AD}{EH}\\\\\dfrac{6}{y}=\dfrac{8}{6}=\dfrac{10}z}=\dfrac{x}{12}[/tex]

First we take,

[tex]\dfrac{6}{y}=\dfrac{8}{6}\\\\y=\dfrac{36}{8}\\\\y=4.5\ units[/tex]

similarly,

[tex]\dfrac{8}{6}=\dfrac{10}{z}\\\\z=\dfrac{60}{8}\\\\z=7.5\ units[/tex]

similarly,

[tex]\dfrac{8}{6}=\dfrac{x}{12}\\\\x=\dfrac{96}{6}\\\\x=16\ units[/tex]

Hence, the value of x = 16 units, y = 4.5 units and z = 7.5 units.

To graph the inequality c ≤ 3, you draw a solid line at 3 on the number line and shade to the left. For c < 3, you draw a dotted line at 3 on the number line and shade to the left, without including 3.

To graph the inequality c ≤ 3, you will draw a line at the value of 3 on the number line and shade the region to the left of the line. This includes the value 3 as well. This is because the inequality includes the symbol ≤, which means 'less than or equal to'.

On the other hand, to graph the inequality c < 3, you will draw a dotted line at the value of 3 on the number line and shade the region to the left of the line. However, this time the value 3 is not included in the solution because the inequality uses the symbol <, which means 'less than'.
