Answer:
1/26
Step-by-step explanation:
For two independent events, you multiply the chances of one event times the chances of the other. .
The chances of heads in the coin flip is 1/2.
There are four 10's out of 52 cards. So 1/13 for that event.
Multiply 1/2 times 1/13 to get 1/26
1. Let
x = first piece
y = second piece
z = third piece
2. Arrange it into an equation
x + y + z = 50
3. The second piece is 4 times as long as the first piece so 4x = y.
The third piece is 5 times as long as the first piece so 5x = z
4. Now substitute the values
x + (4x) + (5x) = 50
5. Simplifying makes the equation into 10x = 50
6. Do the opposite of multiplying to get rid of the 10 which is dividing. Divide 50 by 10.
x = 50/10
x = 5
7. Now substitute x in 4x and 5x
4 * 5 = 20
5 * 5 = 25
8.
x = 5
y = 20
z = 25
Yes, two squares are congruent if their areas are same.
Answer:
Proportion states that the two ratios or fractions are equal
Given the statement:
The scale on map is 2 cm =25 miles.
Dave measured the distance to the next town at 5 cm.
We have to find the what miles away is the next town.
Let x be the distance in miles away is the next town.
By definition of proportion:
By cross multiply we get;
Simplify:
Divide both sides by 2 we get;
x = 6.25 miles
Therefore, 6.25 miles away is the next town.
