3/5 * 5/6
= 15/30
Step-by-step explanation:
So the answer is the third one in line
Answer: The value of x is 3.5
Explanation:
<u>Equation</u>:
y = 2x - 7
When the equation's Line intersects the x-axis, the value of y shall be always 0
<u>Insert y = 0, to find x intercept</u>
⇒ 0 = 2x - 7
⇒ 2x - 7 = 0
⇒ 2x = 7
⇒ x = 3.5
So coordinates: (x, y) → (3.5, 0)
Answer:
a = 36 and a = 27
Step-by-step explanation:
The geometric mean of two numbers is the square root of the product of the two numbers.
Say for example we have the numbers x and y, the geometric mean z is mathematically;
z = √xy
For the first question, our z is 12, x and y are 4 and a respectively.
12 = √4a
square both sides
144 = 4a
a = 144/4
a = 36
For the second question
z is 9, x and y are 3 and a respectively
9 = √3a
square both sides
81 = 3a
a = 81/3
a = 27
Answer:
b, c, and f
just divide 24/30 and youll arrive at .8! .8 is also the same as 8/10 and 80%
