Answer:
C
Step-by-step explanation:
Use the sine ratio in the left, right triangle to find the common side to both triangles and the exact values
sin60° =
, cos45° =
, thus
sin60° =
=
=
( cross- multiply )
2 × opp = 21 ( divide both sides by 2 )
opp = 
Now consider the right triangle on the right, using the cosine ratio
cos45° =
=
=
( cross- multiply )
x =
×
=
→ C
Answer:
16. 
17. 
18. 
19. 
Step-by-step explanation:
Equation is
where k is a constant of proportionality.
16.

So, equation is 
17.

Equation is 
18.

Equation is 
19.

Equation is 
Answer:
2p+3>2(p−3)
Use the distributive property to multiply 2 by p−3.
2p+3>2p−6
Subtract 2p from both sides.
2p+3−2p>−6
Combine 2p and −2p to get 0.
-3>6
This is true for any p.
p∈R

Answer:
The answer is $44.73 and what ever the explain part said on the question is not reasonable.
Step-by-step explanation:
I say this because there are 5 friends and each bill for them is $7.75 so $7.75 times 5 equal $38.75 and then the extra money for dessert is 2.99 but two times so when u add those two to $38.75 it equals $44.73.
Step-by-step explanation:
since all sides of a cube have the same length (same principle as e.g. for a square), this means also the length and width are 10 in long.
the volume is therefore
10 × 10 × 10 = 1000 in³
