Two sides of a triangle measure 8 cm and 15 cm. which could be the length of the third side? 6 cm 18 cm 24 cm 28 cm

The correct answer is:  [B]:  "18 cm ". 

Explanation:

If a, b, c are the three (3) sides of triangle,  then: 

a − b < c > a + b ;  (a ≥ b)

Let "c" = the "third side" ; 

Let "b" = the "first side" ;  {since:  "(a ≥ b)" ;  → "(15 cm ≥ 8 cm)" } ;

Let "a" = the second side" ; {again; since:  "(a ≥ b)" ;  → "(15 cm ≥ 8 cm)" } ;

→ a − b < c > a + b ;  (a ≥ b) .

So;       "side a" = 15 cm ; 

             "side b" =  8 cm ;

             "side c" = the "third side" ; 

→ 15 cm − 8 cm < c > 15 cm + 8 cm ; 

→  7 cm < c > 23 cm ; 

Consider the answer choices: 

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
