V=81 000cm³
V=Ab *h
Ab=L*w
Ab=45*30
Ab=1350cm²
V=1350*h
1350*h=81 000
h=81 000/1 350
h=60cm answer variant b)
Answer:
2 step proof, Subtraction Property
Step-by-step explanation:
This one is pretty easy if you know a shortcut. Addition, Subtraction, Multiplication, and division properties.
Think about it this way. Subtract angle 1 from QUS. Then subtract angle 2 from RUT. Knowing RUT is equal to QUS means that the differences are the same.
Don't know if this is right or not but hope this helps.
Here's my work
The Common Denominator is the bottom part of a fraction which has been matched to 2 or more fractions. For example 1/2 + 1/4 is easier if you use 2/4 + 1/4 = 3/4. You can also use it for 3/5 + 1 2/3 Becomes 3/5 + 5/3 (Improper fraction) and you change that to 9/15 + 25/15 = 34/15 = 2 4/15
