Answer:
a= 20
Step-by-step explanation:
We can use the Pythagorean theorem to solve
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
The diagonal is the hypotenuse and the length and width are the legs
a^2 + 15^2 =25^2
a^2 +225 = 625
Subtract 225 from each side
a^2+225-255=625-225
a^2 = 400
Take the square root of each side
sqrt(a^2) =sqrt(400)
a = 20
Answer:
Step-by-step explanation:
Solution,
Here,
Total distance=200+350m=550m
Time=5 min =5×60sec =300 seconds
Now,
Speed=distance/time
Speed=550/300
Speed=18.33m/s
Again,
Displacement=350m-200m=150m
Velocity=Displacement/time
Velocity=150/300
Velocity=0.5m/s
Answer:
x≤−7
Step-by-step explanation:
Let's solve your inequality step-by-step.
3(x−4)≥5x+2
Step 1: Simplify both sides of the inequality.
3x−12≥5x+2
Step 2: Subtract 5x from both sides.
3x−12−5x≥5x+2−5x
−2x−12≥2
Step 3: Add 12 to both sides.
−2x−12+12≥2+12
−2x≥14
Step 4: Divide both sides by -2.
−2x
−2
≥
