Answer:

d = √91 ft = about 9.53 ft

Step-by-step explanation:

use pythagorean theorem which is a²+b²=c²

(the hypotnuse which is opposite side of the right angle is always going to be C in the pythagorean theorem)

a = 3 b = ? c = 10

(3)² + b² = (10)²

9 + b² = 100

subtract 9 from both sides

b² = 91

take the square root of both sides

b = ±√91

so the side d = √91 ft = about 9.53 ft

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..

Ms cais class is studying a study pattern.the rule for the tile pattern is y=10x-18.kalil thinks that figure 12 of this pattern

Allisa [31]

I assume that x = figure no.

It's better to write this as

Tiles = 10n-18

Thus 10(12) - 18

=120 - 18

= 102

THUS HE IS WRONG.
