Let the money alleli initially had be x
Money after buying clothes = x-(1/2)x=(1/2)x
Money spent on shoes = (1/2)x × (1/3)x=(1/6)x
Remaining money = x minus( (1/2)x + (1/6)x)= (1/3)x
Also we know the remaining money is 1000
Therefore
(1/3)x = 1000
Multiplying 3 on both sides
X = 3×1000
X = 3000
The initial amount she had is 3000
Hope this is right!!
Answer:
Step-by-step explanation:
In general, graphs that go from lower left to upper right have a positive slope (think of it as going up the stairs...positive), and graphs that go from upper left to lower right have a negative slope (think of it as going down the stairs...negative). I don't see graphs here but use this general idea and you'll be fine. Of course, this applies to graphs of lines of the form y = mx + b.
Answer:
P = 2/16 This is based on 14/16 chance that the next pastry will be something else.
Step-by-step explanation:
We can also expand and say P= 2/16 = 1/8
Not P= 7/8
Answer:
The given argument is valid by the law of detachment
Step-by-step explanation:
Law of Detachment states that if the following two statements are true:
(1) If a , then b .
(2) a
Then we can say a third true statement:
(3) b.
Given:
1) If a triangle has an angle with a measure more than 90°, then the triangle is an obtuse triangle.
2) The measure of an angle in △ABC is 110°.
Let the statement a be "If a triangle has an angle with a measure more than 90°" , and b be the statement "the triangle is an obtuse triangle."
then, (1) and (2) can be written as:
1) If a , then b.
2) a
so, by the Law of Detachment, we can say that b is true i.e,
is an obtuse triangle.
