0 to 12 bags is the correct answer, 12 bags will put her at exactly $40. This means she cant have more than 12 bags.
obtuse angle is anything more than 90 degrees
Answer:
C 14
Step-by-step explanation:
7 ×4 ×1/2=14
because triangle area formula is A=1/2×B×H
B= base
H= height
Answer:
You can use a calculator to find all the tan, sin, cos values! Simply enter the number, for example, 52, then press the tan button! For question d, you are finding what number that decimal is the tangent of. Press the 2nd function on your calculator, and you can see that -1 beside the tan. Enter the decimal then use that button to find the reverse tangent.
tan52 = 1.2799
sin19 = 0.3256
cos34 = 0.8290
tan-1(0.9876) = 44.6426
To solve the conveyor belt problem, you'll have to use the sine of 15. (remember, sine = opposite/hypotenuse). Set up an equation:
sin15 = ?/12m
Use a calculator to find sin15, then you can solve it like algebra.
sin15 = ?/12m
sin15*12m = ?
0.2588*12m = ?
3.1056m = ?

Our original value is $1,800. Every 7 years that value doubles, so at 7 years, our value would be $3,600. At 14 years, the value would be $7,200. At 21 years, the value would be $14,400. At 28 years, the value would be $28,800. At 35 years, the value would be $57,600. At 42 years, the value will be $115,200.
I hope this helps!
