Switching the hypothesis and conclusion of a conditional statement<span> and negating both. For example, the </span>contrapositive<span> of "If it is raining then the grass is wet" is "If the grass is not wet then it is not raining."
It's just to negate both sides :)</span>
Answer:
a= 73.2
b =36.6
c = 76.2
Step-by-step explanation:
Perimeter of the triangle is the distance round the triangle.
Let the 3 sides be a, b and c
Side a of the triangle is twice as long as side b. This means
a = 2b
Side c is 3 feet longer than side a. This means
c = a + 3
The perimeter of the triangle is 93 feets. Formula for finding the perimeter of the triangle is
(a + b + c)/2
Therefore,
93 = (2b + b + 2b + 3)/2
93 = (5b + 3)/2
5b + 3 = 93 × 2 = 186
5b = 186 - 3 = 183
b = 183/5 = 36.6
a = 2b = 2 × 36.6 = 73.2
c = a + 3 = 73.2 +3 = 76.2
The answer to this problem is x= -0.5
Pick 1: 6 yellow out of 15 total marbles = 6/15 = 2/5
Pick 2: 6 yellow out of 15 total marbles = 6/15 = 2/5
Pick 1 AND Pick 2
2/5 x 2/5 = 4/25
Convert 1.5 × 108 from scientific notation to standard form. 15,000,000 150,000,000 1,500,000,000 15,000,000,000

Step-by-step explanation:
We need to convert 1.5 × 10⁸ from scientific notation to standard form.
The scientific notation is 1.5 × 10⁸
Out of the given options, we need to choose the correct one.
10⁸ means 100000000
⇒
or
One of the zero from denominator and numerator will cancel down.
So, the correct option is b.
