Answer:
13meters
Step-by-step explanation:
c^2=a^2+b^2
12^2+5^2=169
find squareroot of 169 which is 13meters
Answer:
8 gallons
Step-by-step explanation:
Total gas in the car = 14 gallons
Each hour gas usage = 1.5 gallons
Total hours traveled = 4 hours
Left gas after 4 hours
= 14-1.5(4)
=14-6
=8 gallons
Left gas after t hours
=14-1.5t
Hence the answer is after 4 hours, 8 gallons are left after t hour(s) 14-1.5t
To find the area, you must split the kite into many triangles.
(5*7*0.5)*2 + (4*5*0.5)*2 = 55
Answer: 55 square meters
Answer:
second option
Step-by-step explanation:
Pythagoras for right-angled triangles :
c² = a² + b²
c is the Hypotenuse, the line opposite of the 90 degree angle.
a and b are the other 2 sides.
the distance between 2 points is the Hypotenuse of a right-angled triangle of the coordinate differences in x and y.
so, we have (-2, -3) and (3, 2)
distance² = (x1 - x2)² + (y1 - y2)² = (-2 - 3)² + (-3 - 2)² =
= (-5)² + (-5)² = 25 + 25 = 2×25 = 50
distance = sqrt(50) = sqrt(2×25) = 5×sqrt(2)
Answer:
420,000 J/Kg
Step-by-step explanation:
energy= temperature change* mass* specific heat capacity
energy= 20*5*4200
energy= 420,000
