A = bh
b = 4h
A = 324
324 = 4h * h
324 = 4h^2
324/4 = h^2
81 = h^2
sqrt 81 = h
9 = h
b = 4h
b = 4(9)
b = 36
so the height (h) = 9 cm and the base (b) = 36 cm
Answer:
x ≈ 8.3 ( to the nearest tenth )
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos41° = 
= 
= 
Multiply both sides by 11
11 × cos41° = x, thus
x ≈ 8.3
Answer:
X=16
Step-by-step explanation:
Solve 3(x-9)=21 IF X = 16
16-9 = 7
3X7= 21
A) d+q=20
0.1d+0.25q=4.40 Let's just read what this says: first, # of dimes (d) plus # of quarters (q) is 20.The second equation can be called the VALUE EQUATION; it says that one tenth of a dollar ($0.10) times the # of dimes is part of the total monetary value, and that one quarter of a dollar ($0.25) times the # of 'quarter' coins is the other part of this stash, and it totals $4.40. VOTE FOR A.
