Answer:
f = 6
Step-by-step explanation:
<u>Plug in what you know then solve:</u>
f = d + 1
f = 5 + 1
f = 6
Answer:
Full bottle can fill 34 ounces water and 27.2 ounces left in the bottle
Step-by-step explanation:
Full bottle : 100%
6.8 ounces: 20%
100% / 20% = 5
Full bottle = 6.8 x 5 = 34 ounces
water remain in bottle = 34 -6.8 = 27.2 ounces

The value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We know that:
P + Q are complementary, which means that
P+Q = 90°
Then R is a right angle, i.e. it measures 90°.
sin(90-x) = cos (x)
cos(90-x) = sin (x)
Then sinQ = 4/5
cos(90-Q) = cosP = 4/5
Now sin²(P) + cos²(P) = 1
sin²(P) = 1 - cos²(P)
sin²(P) = 1 -[4/5]² =9/25
sin(P) = 3/5
cos(Q) = sin(P) = 3/5
cos(P) + cos(Q) = 4/5 + 3/5 = 7/5
Thus, the value of the cos P + cos Q is 7/5 if sin Q = 4/5 after applying the identities of trigonometric.
