First, note that 1 m =100 cm.
Then
5 m = 500 cm;
3 m = 300 cm.
If Elena wants to make a scale drawing of her bedroom on a scale of 1 to 50, then
500 cm : 50 = 10 cm;
300 cm : 50 = 6 cm.
Therefore, the length of the scale drawing is 10 cm and the width of the scale drawing is 6 cm.
Answer:
Step-by-step explanation:
We never did inverse propositions when I had logic. The inverse of
if P then Q
is the proposition
if not P then not Q
We have
P: A triangle has three congruent angles
Q: it is an equilangular triangle
The inverse is thus if not P then not Q
If a triangle does not have three congruent angles then it is not an equilangular triangle.
Answer: First choice
The reason we didn't do inverses is it has the same truth value as the converse; the inverse is the contrapositive of the converse.
Answer:
-17/14
Step-by-step explanation:
To subtract fractions, you must have a common denominator. If that is not given, you make it.
You do so buy finding the LCM of denominators:
LCM of 7 and 2 = 14
Now, here you have multiplied the denominators either by 7 or 2. You do the same for the respective numerators:
2x2/14 - 3x7/14 = 4/14 - 21/14.
Now that you have the same denominator, subtract the numerators:
4-21 = - 17
Put it back as a fraction : -17/14
hope this helps.
