Answer:
x = 0.72
Step-by-step explanation:
Given
3.8x = 2.736 ( divide both sides by 3.8 )
x = 0.72
Answer:
1/6 hours
Step-by-step explanation:
It takes leo 15 minutes = 15/60 = 0.25 hours to circle to school with speed of
12km/hr .
Distance covered = speed*Time.
Distance covered = 12*0.25
Distance covered= 3 km
So the distance to be covered each time is 3km.
If speed increase to 18 km/he
Time taken = distance/speed
Time taken = 3/18
Time= 1/6 hour
Or 1/6 * 60 = 60/6 = 10 minutes
Answer:
The third choice
Step-by-step explanation:
We need to find the slope and y-intercept of the line and then put it into y = mx = b form. To find the slope, pick a point on the line; I will use (-2, 5); count how many units up you need to go to get to the next point on the line, which in this case it would be 3. The count how many to the right or left you would need to go, which is 1 to the left. Moving left means a negative, so it is -1. Your slope fraction would be , since slope is rise over run. You can sub this fraction in for m in y = mx + b, which will give you a revised equation of y = -3x = b. To find the y intercept, or b, just find the point where the line crosses the y-axis, which is -1. So, the equation is now y = -3x - 1.The correct answer is third choice.
We have an rectangle triangle
Pythagoras therorem:
hypotenuse²=side₁²+side₂²
hypotenuse=61 feet
side₁=11 feet
side₂=height
(61 feet)²=(11 feet)²+ side₂²
3721 ft²=121 ft²+ side₂²
side₂²=3721 ft²-121 ft²
side₂²=3600 ft²
side₂=√(3600 ft²)
side₂=60 ft.
heigth=60 feet
Answer:
Step-by-step explanation:
The slope is , which matches the second option.
