Answer:
12 cm
Step-by-step explanation:
Well first we can cut the triangle in half and use the Pythagorean theorm
a^2+b^2=c^2
In this case we are going to be doing c^2-a^2=b^2
10^2-8^2=b^2
(10*10)-(8*8)=b^2
100-64=b^2
36=b^2
Now we just square root 36 (what number times itself is 36)

b=6
Since half of the one side equals 6 (DC) then the length of AC is 12!
The answer is 1.5 because of my calculations
Answer:
<h2>
2.4 Litres of water</h2>
Step-by-step explanation:
80% of (3 litres)
You can take 3 litres to be 3000 ml which is how I solved it.
<h2>
OPTION 1</h2><h2>
_________</h2>
80/100 x 3000
=2400 or 2.4 litres
The same can go with not taking ml which you can just use litres
<h2>
OPTION 2</h2><h2>
_________</h2>
80/100 x 3
=2.4 litres
I used the ml since I do not need the calculator for that one and it is faster to calculate.
The product is 28. 11-7= 4. 4×7=28
