Answer:
5mL
Step-by-step explanation:
Volume is mass
12.5 is 25% of x
percent means parts out of 100
25%=25/100=1/4
12.5=1/4 of a number
mulitply both sides by 4
50=number
the number is 50
Answer:
3. angles forming a linear pair to sum to 180
4. Def of supplementary angles
A(1, 1), B(7, 1), C(1, 9)
AB = 7 - 1 = 6
AC = 9 - 1 = 8
Use the Pythagorean theorem:
AB² + AC² = BC²
Substitute:
BC² = 6² + 8²
BC² = 36 + 64
BC² = 100 → BC = √100 → BC = 10
The perimeter of ΔABC:
P = 6 + 8 + 10 = 24
<h3>Answer: 24 units</h3>
