I first used substitution to get my answer and then used graphing to check. You can easily get a graphing equation by rearranging the second equation.<span />
Answer:
8 pints because 16 cups is one gallon so 4 pints is one gallon
Step-by-step explanation:
Answer:
<u>Option B. sin(s) = cos(u)</u>
Step-by-step explanation:
The rest of the question is the attached figure.
Complementary angles - two angles that add to 90 degrees.
The sine of one of them will be equal to the cosine of other angle.
For the attached figure:
The set all complementary angles are:
- angle s and angle t
- angle u and angle v
- angle s and angle u
- angle t and angle v
We will check the options:
A. sin(t) = sin(u) ⇒(<u>wrong</u>) because t and u are not complementary angles
B. sin(s) = cos(u) ⇒ (<u>True</u>) ⇒ s and u are complementary angles and sine of one of them will be equal to the cosine of other angle.
C. cos(s) = sin(v) ⇒(<u>wrong</u>) because t and u are not complementary angles
D. cos(t) = cos(v) ⇒(<u>wrong</u>) because t and v are complementary angles but sine of one of them should be equal to the cosine of other angle.
<u>The answer is option B. sin(s) = cos(u)</u>
I think it’s 26.4
