Answer:

B. {16, 19, 20}

Step-by-step explanation:

The triangle inequality requires for any sides a, b, c you must have ...

a + b > c

b + c > a

c + a > b

The net result of those requirements are ...

the sum of the two shortest sides must be greater than the longest side
the length of the third side lies between the difference and sum of the other two sides

If we look at the offered side length choices, we see ...

A: 8+11 = 19 . . . not > 19; not a triangle

B: 16+19 = 35 > 20; could be a triangle

C: 3+4 = 7 . . . not > 8; not a triangle

D: 5+5 = 10 . . . not > 11; not a triangle

The side lengths {16, 19, 20} could represent the sides of a triangle.

Additional comment

The version of triangle inequality shown above ensures that a triangle will have non-zero area.

The alternative version of the triangle inequality uses ≥ instead of >. Triangles where a+b=c will look like a line segment--they will have zero area. Many authors disallow this case. (If it were allowed, then {8, 11, 19} would also be a "triangle.")

PLEASE HELP!!!!! WILL GIVE BRAINLIEST!!!

enyata [817]

She burns 250 by herself and she burns 3 times as many with her sister.

Multiply the calories by herself by 3:

250 x 3 = 750

Now you need to multiply that by the number of hours.

The formula is a. t[c(h)] = 750h

Combine the like terms to create an equivalent expression: 3 + 2 + (52) + 6

devlian [24]

It would be -2z+8. Because 3z+-5 is -2 and 2+6 is 8.

I wonder if I did #9 right and I’m having trouble with #10

yaroslaw [1]

Let's see....

QUESTION: Add. Write your answer as a mixed number in simplest form.

$6 \frac{7}{9} + 9 \frac{8}{9}$

1. Rewriting our equation with parts separated

 $=6+ \frac{7}{9} +9+ \frac{8}{9}$

2. Solving the whole number parts

 $6+9=15$

3. Solving the fraction parts

 $\frac{7}{9} + \frac{8}{9} = \frac{15}{9}$

4. Reducing the fraction part, 15/9,

 $\frac{15}{9} = \frac{5}{3}$

5. Simplifying the fraction part, 5/3,

 $\frac{5}{3} = 1\frac{2}{3}$

6. Combining the whole and fraction parts

 $15+1+ \frac{2}{3} =16 \frac{2}{3}$

ANSWER: $16\frac{2}{3}$

Hope that helps!
