Step-by-step explanation:
to round 4.645 to the nearest whole number consider the tenths’ value of 4.645, which is 6 and equal or more than 5. Therefore, we have to round up: the whole number part of 4.645, 4, increases by 1 to 5, and the decimal point and all digits (.645) are removed.
4.645 rounded to the nearest whole number = 5
The answer is “the initial deposit is $200” and “the annual interest rate is 1.5%”
Since the line bisects the right angle of the larger triangle, the angle opposite 3 in the triangle on top is 45 degrees (90/2 = 45).
sin 45 = 3/x
= ![\frac{3}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7Bx%7D)
x = 3![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
the answer is 40 minute's 250-210 is 40
