7 0

Answer:

Option D, 110

Step-by-step explanation:

first we find x

10x+20-80=2(2x+15)

or, x=15

now, 10x+20 = 170

so, z = 360-170-80 = 110

What is the area of a circle?
Andru [333]

The area of a circle is the size of the 2-dimensional space inside the circle's
closed curved boundary.

The area can be calculated in terms of known linear measurements of the circle:

-- Area  =  (π) x (radius)²

-- Area  =  (π/4) x (diameter)²

-- Area  =  (1/2) x (circumference) x (radius)

-- Area  =  (1/4) x (circumference) x (diameter)

Any of these formulas will give you the area.  The one you decide to use
just depends on what you already know about the circle.

11111nata11111 [884]

The store which offers the greater discount is store B.

<h3>Discount</h3>

Store A:

First week = 10%

= 10/100

= 0.1

Second week = 20%

= 20/100

= 0.2

Total discount = (0.1 + 0.2) / 2

= 0.15

Store B:

25%

= 25/100

= 0.25

Therefore, the store which offers the greater discount is store B.

Is it possible to find a value of $x$ so that the value of the surface area (in square inches) is equal to the value of the volu
Annette [7]

The box has volume

11 in × 3 in × <em>x</em> in = 33<em>x</em> in³

and surface area

2 (11 in × 3 in + 11 in × <em>x</em> in + 3 in × <em>x</em> in) = (66 + 28<em>x</em>) in²

The volume and area have the same value if

33<em>x</em> = 66 + 28<em>x</em>

Solve this equation for <em>x</em> :

33<em>x</em> - 28<em>x</em> = 66

5<em>x</em> = 66

<em>x</em> = 66/5 = 13.2
