Which value is included in the solution set for the inequality graphed on the number line?

Estimate the total cost of 31 televisions at £196.50 each and 19 DVD players at £50.99 each

Gwar [14]

Answer:

Solution,

Cost of one television=£196.50

cost of 31 televisions:

 $= 196.50 \times 31 \\ = 6091.5$ 

Cost of one DVD player=£50.99

Cost of 19 DVD player:

 $= 50.99 \times 19 \\ = 968.81$ 

Now,

Total cost

= cost of 31 televisions + cost of 19 DVD player

=6091.5+968.81

=£7060.31

Hope this helps...

Good luck on your assignment..

Find the surface area of the composite solid. Round your answer to the nearest hundredth.

horrorfan [7]

Answer:

The answer is

A. 529.66 ft²

Step-by-step explanation:

The picture of the composite figure is not given,

But find attached the figure.

The composite consists of two solid shapes

1. Cylinder

2. Rectangular prism

To solve for the total surface area of the composite

Let us solve for the total surface area of the cylinder

Given radius r= 4ft

Height h=5ft

A= πr²+2πrh-πr²

N/B we subtracted the second circular surface since it is joined to the rectangular prism

A= 3.142*4²+2(3.142)*4*5-3.142*4²

A= 50.272+125.68-50.272

A=125.68ft²

We proceed to find the area of the rectangular prism

We know that the prism has 6 sides

Hence area

A= 2(11*6)+ 2(8*6)+2(11*8)

A= 132+96+176

A= 404ft²

Hence total surface area is

404+125.68= 529.68ft²

Find angle ADB of the equation

Aloiza [94]

Answer:

$m\angle ADB = 59\°$ .

Step-by-step explanation:

Given:

$\angle BDC = 31\°$

We need to find $\angle ADB$ .

Solution:

Now we can see that given figure is a rectangle with diagonals drawn in it.

So by properties of rectangle which states that;

"All angles of a rectangle are 90°."

So we can say that;

$\angle A = \angle B = \angle C = \angle D = 90\°$

But

$\angle D = \angle BDC + \angle ADB$

Substituting the values we get;

$31\°+\angle ADB = 90\°$

Subtracting both side by by 31 we get;

$31\°+\angle ADB -31\°= 90\°-31\°\\\\m\angle ADB = 59\°$

Hence $m\angle ADB = 59\°$ .
