A triangle has three different integer side lengths and a perimeter of 20 units. What is the max length of any one side?

Troyanec [42]

X + x+1 + x + 2 = 20
3x + 3 = 20
3x = 17 but can't start with x = 6 because 6+7+8 > 20,
so have start with 5 + 6 + 7 = 18 are the 3 sides.

what is the acceleration of a baseball when its speed increases from 1 m/sec to 25 m/sec in 1 second?

kirill115 [55]

Answer:

24 m/s²

Step-by-step explanation:

Acceleration is change in velocity over time.

a = Δv / Δt

a = (25 m/s − 1 m/s) / 1 s

a = 24 m/s²

Help me answer this please!!! i will mark you brainliest

Answer:

363 ft.

Step-by-step explanation:

To calculate the base side which is b we use the trigonometric identity called cosine.

$cos \theta=\frac{base}{hypotenuse} \\\\cos25 = \frac{b}{400}\\\\b=400*cos 25\\b=400*0.906\\b=362.5\ ft$

Since we the answer to the nearest whole number it would be b = 363 ft.
