5:4 You just put a Colen In the middle EDIT*THERE WOULD ACTUALLY BE A INFINITE AMOUNT OF ANSWER FOR EXAMPLE IT COULD BE 10:8 BECAUSE YOU MULTIPLY BY 2 SO EVERY TIME U DO DAT U HAVE MANY ANSWERS.
Answer:
20:25
Step-by-step explanation:
add how many parts (4+5=9)
45/9=5
4*5=20, 5*5=25
therefore, 20:25
Answer:
3,4,55 by-step explanation:
We determine first the real dimension of the circular fountain by using the scale factor given.
(18 cm) x (4 ft / 3 cm) = 24 ft
Then, calculate for the area of the base of the circular fountain by the equation,
A = πD²/4
where A is are and D is diameter. Substituting,
A = π(24 ft)²/4 = 144π ft² ≈ 452.4 ft²
Thus, the area of the base of the circular fountain is approximately 452.4 ft².
Answer:
the area is 68 feet
Step-by-step explanation:
-first pretend that one spot is filled and if you do that the whole rectangle is 8 by 10.
- the area of something is length times width and so 8 times 10 is 80
- however, we can't pretend that we don't have a hole anymore so to figure out that tiny rectangles area we have to find its width and length which is 4 and 3.
- 4 times 3 is 12 and since we have that we subtract 12 from 80 and we get 68.
