Answer:
Step-by-step explanation:
First change 4 3/10 to 4.3. Then you change 4.3 + -6.2 to 4.3 - 6.2.
Then you do 4.3 - 6.2 and you should get - 1.9.
1 apple is $.30. $.30 times 7 = $2.10.
Answer:
8. -6
Step-by-step explanation:
Answer:
The angle between the ramp and the horizontal is 11.54 degrees
Step-by-step explanation:
Here, we want to get the angle between the ramp and the horizontal
What we have to do here is to bring the measure of 2 m near to the edge leftwards, so we can have a right triangle
Now, the angle we want to calculate is the angle that faces the measure 2 m
The given measure of 10 m will represent the hypotenuse of the right triangle
The trigonometric ratio that links the hypotenuse and the opposite is the sine
The sine is the ratio of the opposite to the hypotenuse
Thus, we have it that;
sin theta = opp/hyp
sin theta = 2/10
sin theta = 0.2
theta = sin^-1 0.2
theta = 11.54
Answer: Radio waves. Next longer is visible, ultraviolet, and shortest is x-rays.
Step-by-step explanation:
Just a fact. Radio waves also have the lowest energy and frequency. This is a physics question.
Wavelength = speed of light/frequency
Meters = meters per second / Hertz
= meters / second × seconds
Energy = Planck's constant times frequency.
