Answer:
l = 9 cm
Step-by-step explanation:
Using Pythagoras' identity in one of the right triangles with legs width w, length l and hypotenuse h , then
l² + w² = h²
l² + 12² = 15²
l² + 144 = 225 ( subtract 144 from both sides )
l² = 81 ( take the square root of both sides )
l = 
= 9
Answer:
5
Step-by-step explanation:
We know that we can use the Pythagorean theorem
a^2 + b^2 =c^2
where a and b are the legs and c is the hypotenuse
one of the legs is 12 and the hypotenuse (diagonal) is 15
a^2 + 12^2 = 15^2
a^2 +144 = 169
a^2 +144-144 =169-144
a^2 = 25
Taking the square root of each side
sqrt(a^2) = sqrt(25)
a = 5

The answer is A!! Hope I helped
We would have to convert 3/4 to a decimal of 0.75 (the equivalent)
0.75*23 = 17.3
-or-
3 * 23 = 69
4 * 23 = 92
Answer:
a: 448 gallons
b: 5 fish
Step-by-step explanation:
66 is the answer
76+ 38= 114
114+ 66 = 180
