That way is:
6 $4
15 ?
4×15=60
60÷6=10
so answer is $10
Answer: 12
Step-by-step explanation:
You can use what is called geometric mean to solve this.
The hypotenuse of this triangle is split into two sections. One section corresponds to/equal to the altitude which is our "X", which corresponds to/equal to the second section.
You find "X" by using geometric mean and the proportion:
16/X=X/9
Then cross multiply to get 16 x 9= 144
then 144=x²
Solve for X.
X=12
It would be 3/10
(100 pennies in a dollar)
($3 dollars = 300 pennies)
90 x
----- ------
300 100
cross mutiply and divide
90 x 100 = 9000
9000/300 = 30
30/100 = 3/10
Answer:
2(C)
Step-by-step explanation:
You can use the slope formula to answer this which is y₁ - y₂ divided by x₁ - x₂. Let's say that (x₁, y₁) is (6,6) and the (x₂, y₂) is (1, -4). We can then substitute these values into the formula.
This would become 6- (-4) divided by 6-1.
This can be further simplified as shown:
=6+4 divided by 5
=10/5
=2
Therefore, 2 is the slope of the line
