Answer:

x > -2/5

Step-by-step explanation:

To solve this, you need to divide -5 on both sides to isolate x.

-5x < 2

x > -2/5

Because we divided by a negative number, the sign has to change direction.

−y+3 ≤ 8 and y+2>9 Solve the inequality

ankoles [38]

Answer:

y > 7

Step-by-step explanation:

The solution to the first inequality can be found by adding y-8 to it:

-5 ≤ y

The solution to the second can be found by subtracting 2 from it:

y > 7

Since the solution must satisfy both inequalities, the intersection of the partial solutions is the solution space. The area of overlap of these partial solutions is ...

The radius of circle A is three feet less than twice the diameter of circle B. If the sun mmm of the diameters of both circles i

yanalaym [24]

Answer:

Area of Circle A = 1133.54

Circumference of Circle A= 119.32

Step-by-step explanation:

Given: Sum of both circle diameters= 49 feet.

Circle A radius= Three feet less than twice the diameter of circle B.

Lets assume diameter of Circle B is "x"

∴ Circle A radius (r)= $(2x-3)$

We know, the diameter of circle is $2r$

Diameter of Circle A is $2\times (2x-3)$

Next as given sum of both circle diameter is 49 feet.

∴ $2(2x-3)+x= 49\ feet$

distributing 2 with 2x and -3

⇒ $4x-6+x= 49$

⇒ $5x-6= 49$

Adding both side by 6

⇒ $5x=55$

Cross multiplying both side.

⇒ $x=\frac{55}{5} = 11$

∴ Diameter of circle B is 11 feet.

Next, subtituting the value of x to get the value of radius for Circle A.

Radius of circle A= $(2x-3)$

⇒ Radius of circle A= $(2\times 11-3)= 22-3$

∴ Radius of circle A= 19 feet.

Area of circle= $\pi r^{2}$

Taking π= 3.14

Area of circle A= $3.14\times 19^{2} = 3.14\times 361$

∴ Area of circle A= 1133.54

Circumference of circle= 2πr

Circumference of Circle A= $2\times 3.14\times 19= 119.32$

∴ Circumference of Circle A= 119.32

$\huge\pink{\fbox{\underline{\underline{\maltese{Answer}\maltese}}}}$

$\\$

Ratio of the sides of the similar triangles are equal ,

$\frac{DG}{EF} = \frac{CD}{CE}$

=> $\frac{10}{30} = \frac{9x–3}{36}$

=> $9x – 3 = \frac{36}{3}$

=> $9x – 3 = 12$

=> $9x = 15$

=> $x = \frac{15}{9}$

=> $x = \frac{5}{3}$
