Jim is given $10 every day.if he spends $7 every day and saves the rest,how much does he save in a week?

Amount saved every day

$ 10 - $7 = $3


Amount saved in a week

$3 x 7 = $21


$21

21 dollars
Because if he gains 10 dollars every day for a week multiply 10 by (for the days in a week) and you should get 70. Then because he uses 7 of those 10 dollars multiply 7 by 7 to get 49 and that is how much he used so then you need to take 70 and subtract 49 which should give you 21

Question 1:

sin(t) = 0.29
t = sin⁻¹(0.29)
t = 16.86°

this value of sin(t) is in quadrant 1, as shown below. all trigonometric function in quadrant 1 is positive. in quadrant 2, only sine function is positive. in quadrant 2, sin(t) = 0.29 is given by the value of t = 180°-16.86° = 163.2°

sin(w) = 0.43
w = sin⁻¹ 0.43
w = 25.47°

in quadrant 2, sin(w) = 0.43 is given by the value of w = 180°-25.47° = 154.58°

163.2° > 154.53° = t > w

question 2:

cos(t) = -0.42
t = cos⁻¹ (-0.42)
t = 114.8

this value of t is in quadrant 2, where the value of cosine is negative. in quadrant 3, the value of cos(t) = -0.42 is given by t = 180°+65.2° = 245.2°

cos(w) = -0.80
w = cos⁻¹ (-0.80)
w = 143.13

in quadrant 3, the value of cos(t) = -0.80 is given by t = 180°+36.87° = 216.87°

245.2° > 216.87° = t > w
