Answer:
I'm not totally sure but I do think the answer is yes
The answer to your question would be 60 percent all you do is divide that and move the decimal 2 places to the left.
Answer:
The area is 83.905 cm^3
Step-by-step explanation:
The total ratio is 9 + 7 + 6 = 22
So the length of the sides are as follows;
9/22 * 44 = 18 cm
7/22 * 44 = 14 cm
6/22 * 44 = 12cm
we can use Heron’s formula to find the area of the triangle
we find a first
s = (a + b + c)/2 = (18+14+12)/2 = 44/2 = 22
Mathematically, the Heron’s formula is as follows;
A = √s(s-a)(s-b)(s-c)
where a, b and c are 18,14 and 12 respectively
Plugging the values, we have;
A = √22(22-18)(22-14)(22-12)
A = √(22 * 4 * 8 * 10)
A = √(7,040)
A = 83.905 cm^3
Answer:
= 9000³
Step-by-step explanation:
*Volume of the bigger box :-
20 × 20 × 20 = 8000
*Volume of the smaller box :-
10 × 10 × 10 = 1000
Therefore, volume of the aquarium :-
= 8000 + 1000 = 9000³
Answer:
The road width is x = 10 m.
Step-by-step explanation:
A formula for the area of the horizontal rectangle is A1 = (x)(20 m).
A formula for the small rectangle on top of that is A2 = (x)(18 - x).
The total area of the new roadway is 280 m^2.
Summing up A1 and A2 and equating the result to 280 m^2, we get:
20x + 18x - x^2 = 280
Rewriting this in the standard quadratic form:
-x^2 + 38x - 280 = 0
Here the coefficients are a = -1, b = 38 and c = -280.
The discriminant is thus b^2 - 4ac, or:
38^2 - 4(-1)(-280) = 1444 - 4(280) = 324, or 18^2.
Thus, the roots (x-values) are:
-38 ± 18
-------------- = 28 and 10
-2
Only the value x = 10 makes sense here, so we omit the other value (28).
The road width is x = 10 m.
x = ----------------------
