Answer:
The redaction does not explain the situation. If we assume that 15 balloons were used to make one ballon poodle and three giraffes, then the answer would be 7,5 balloons for 1 poodle, and 2,5 balloons for a giraffe
Step-by-step explanation:
With 15 balloons we make 1 poodle and 3 giraffes. This means that 7,5 balloons were used to make 1 poodle, and other 7,5 balloons were used to make 3 giraffes.
If we divide 7,5 balloons between 3, we obtain 2,5. This means that with 2,5 balloons we make 1 giraffe
I'd start by writing an equation for each of the right triangles. (Pythagorean theorem)
y² + 9² = z²
x² + z² = (4+9)²
4² + y² = x²
we want to find z so combine the equations by substituting the other variables x,y out.
substitute y² for (x² - 4²) in 1st equation.
(x² - 4²) + 9² = z²
now by rearranging the 2nd equation we can substitute x² for (13² - z²)
(13² - z²) - 4² + 9² = z²
169 - z² - 16 + 81 = z²
234 - z² = z²
234 = 2z²
234/2 = z²
117 = z²
√(117) = z
√(9*13) = z
3√(13) = z
13 goes in the box
Answer:
B = 119! The answer is 119!
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
Notice:
32 = (8 x 4)
72 = (8 x 9)
Hence,
32 + 72
= (8 x 4) + (8 x 9) (factorize out the 8)
= 8 x (4 + 9)
therefore the musing number is 8
