Answer:

[tex]\displaystyle \frac{\frac{9}{-5}}{\frac{-3}{8}}=\frac{24}{5}[/tex]

Step-by-step explanation:

Operations With Fractions

The division of the fractions \frac{a}{b} and \frac{c}{d} can be calculated by multiplying the first by the reciprocal of the second fraction:

[tex]\displaystyle \frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a}{b}*\frac{d}{c}[/tex]

We are given the following division of fractions:

[tex]\displaystyle \frac{\frac{9}{-5}}{\frac{-3}{8}}=\frac{9}{-5}*\frac{8}{-3}[/tex]

Multiplying and simplifying:

[tex]\displaystyle \frac{\frac{9}{-5}}{\frac{-3}{8}}=\frac{9}{5}*\frac{8}{3}[/tex]

[tex]\displaystyle \frac{\frac{9}{-5}}{\frac{-3}{8}}=\frac{9*8}{5*3}[/tex]

Simplifying by 3:

[tex]\displaystyle \frac{\frac{9}{-5}}{\frac{-3}{8}}=\frac{3*8}{5}[/tex]

[tex]\mathbf{\displaystyle \frac{\frac{9}{-5}}{\frac{-3}{8}}=\frac{24}{5}}[/tex]

Answer:

216[tex]\pi[/tex]

Step-by-step explanation:

Given the figure.

And the perimeter in the ratio 4: 2: 1.

Perimeter of smallest circle = [tex]8\pi[/tex]

To find:

Area of shaded region.

Solution:

To find the area, we need to have radius first.

And radius can be calculated by the given perimeter.

Formula for Perimeter is given as:

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

[tex]8\pi = 2\pi r\\\Rightarrow r = 4\ cm[/tex]

Radius of smallest circle = 4 cm

Ratio of perimeter is equal to the ratio of the radii.

Radius of 2nd smallest circle by the given ratio = 8 cm

Radius of largest circle = 16 cm

Area of a circle is given the formula:

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

Area of the smallest circle = [tex]\pi 4^2 = 16\pi\ cm^2[/tex]

Area of the 2nd smallest circle = [tex]\pi 8^2 = 64\pi\ cm^2[/tex]

Area of the largest circle = [tex]\pi 16^2 = 256\pi\ cm^2[/tex]

Area of the shaded region = Area of largest circle + 2 [tex]\times[/tex] Area of 2nd smallest circle + 3 [tex]\times[/tex] Area of smallest circle - 2 [tex]\times[/tex] Area of smallest circle - 3 [tex]\times[/tex] Area of 2nd smallest circle

Area of the shaded region = Area of largest circle - Area of 2nd smallest circle + Area of smallest circle = [tex]256\pi - 64\pi +16\pi = 216\pi[/tex]

Answer:

C(t) = 25+34.37t

Step-by-step explanation:

It is given that,

The monthly fee to be a member is $25 and the total cost of membership, including the joining fee, would be $300 for 8 months.

We need to write an equation for C in terms of t representing the total cost of the gym membership over t months.

At t=0, Jonathan pays $25 as joining fee.

Equation will be :

C(t) = Co+kt

Initially, Co = 25

C(t) = 25

At t = 8,

C(8) = 25 + k(8) = 300

8k = 275

k = 34.37

⇒ C(t) = 25+34.37t

Hence, this is the required equation.

Step-by-step explanation:

since the dilatation is centred at the origin , then multiply each of the coordinates of A, B, C by the scale factor 2, that is

A' = (2(- 2), 2(- 2) ) = A'(- 4, - 4 )

B' = (2(1), 2(- 1) ) = B'(2, - 2 )

C' = (2(2), 2(0) ) = C'(4, 0 )

Answer:

BCA = 20 degrees

Step-by-step explanation:

A rhombus is an equilateral quadrilateral, with all four of its sides having the same length. In addition to that, one important geometric property that will really help us with this problem is the fact that the opposite sides of a rhombus are parallel.

This means that BC ||AD.

Consequently, because  BC ||AD,

m∠CAD = m∠BCA.

This is because they are alternate angles.

The alternate angle equality can be used in geometrical problems where you detect two parallel lines cut across by a transversal. in this, our case, the parallel lines BC and AD were transversed by AC.

This makes m∠CAD = m∠BCA because they are alternate angles)

Step-by-step explanation:

Answer:

The area of the rectangle VWXY is 52 square units

Step-by-step explanation:

The formula of the area of the rectangle is A = L × W, where

From the given figure

∵ VWXY is a rectangle

∵ V = (3, -9) and W = (-1, -9)

∵ X = (-1, 4) and Y = (3, 4)

∵ Its length is WX or VY

∴ WX = VY

∵ Its width is VW or XY

∴ VW = XY

→ Let us find its length and its width

∵ Points W and X have the same x-coordinates

∴ y1 = -9 and y2 = 4

→ By using the 4th note above

∴ WX = 4 - -9 = 4 + 9 = 13  

∴ L = 13 units

∵ Points X and Y have the same y-coordinates

∴ x1 = -1 and x2 = 3

→ By using the 3rd note above

∴ XY = 3 - -1 = 3 + 1 = 4  

∴ W = 4 units

→ By using the formula of the area above

∵ A = 13 × 4

∴ A = 52 square units

∴ The area of the rectangle VWXY is 52 square units

Step-by-step explanation:

450 - 396 = 54

(54/450) * 100% = 12%

Hence the decrease is 12%.

Answer:

Step-by-step explanation:

The way to solve is to divide the number.

396/450 = 0.88 or 88%

Now, we subtract 88 from 100 to get 12, since we wanted the percent decrease.

Answer:  √117

Step-by-step explanation:

Since no diagram present, am assuming hypotenuse AB and right angle C.  Let side opp angle B be b, and side opposite angle A be a. Altitude CD is x.

a^2 + b^2 = 22^2 (Pythagorean)

Using Pythag on two smaller triangles,

x^2 + 13^2 = a^2

x^2 + 9^2 = b^2

Substituting in first equation,

x^2 + 13^2 + x^2 + 9^2 = 22^2

x^2 = 117, so x = √117
