There is a string of red and blue lights strung around a window. The red lights blink every 3 seconds٫ and the blue lights blink every 5 seconds. How many times will they blink at the same time in one minute?

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

okey so the slope is -3/5 and the y -intercept is 7/5

hope this if needed hmu
