Answer:
B. x ~ 5
Step-by-step explanation:
This is a right isosceles triangle!
Answer:
The x-coordinate of the solution is -4.
Step-by-step explanation:
The given system of equations have two equation.
........ (1)
...... (2)
Use elimination method to solve the equation (1) and (2).
Multiply equation (1) by 3.
..... (3)
Multiply equation (2) by 2.
.....(4)
Add equation (3) and (4).
Divide both sides by 21.
Put this value in equation 1.
The solution of the system of equations is (-4,9). Therefore the x-coordinate of the solution is -4.
Answer:
50.2
Step-by-step explanation:
Area=π×r2 =π×(4 cm)2 =16π)cm2≈50.24 cm
Step-by-step explanation:
can you send a picture so we can see at least?
A) Minute Hand:
in 1 hour (= 60 minute) the minute hand travels 360 °
So in each minute, the minute hand travels 360/60 = 6°
And in x minute it will travel x.(6°)
B) Hour Hand:
in 1 hour (= 60 minute) the hour hand travels 360/12 = 30°
So in each minute, the hour hand will travel 30°/60° = 0.5°
And in x minute it will travel x.(0.5°)
ANGLE AT 4:35?
At 4:00, angle = 4. 30 = 120°
After 35 minutes, the minute hand strops at 35.(6°) = 210°, but during this 35 minute, the hour hand traveled 35.(0.5) = 17.5°, on top of its 120°, that makes an angle of 137.5°
So at 4:35 the angle between the hour & minute hand = 210°-137.5° =72.5°
Answer A
