Answer:
$5?
Step-by-step explanation:
3 x 4=12
12 is a dosen
1.25 x 4=5
The answer is x=-4, (3<span>±i)/2</span>
Answer:
x ≈ 4.2 (nearest tenth)
Step-by-step explanation:
The chord of length 4 is the base of an isosceles triangle with height of 3.7 and sides equal to the radius (x).
An isosceles triangle comprises two right triangles, each with:
- base = 2 units
- height = 3.7 units
- hypotenuse = x units
Therefore, to find x use Pythagoras' Theorem: a² + b² = c²
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
⇒ a² + b² = c²
⇒ 2² + 3.7² = x²
⇒ x² = 17.69
⇒ x = √(17.69)
⇒ x = 4.2 (nearest tenth)
Option 2:
is the right answer
Step-by-step explanation:
We have to convert the details given in Plan one to an equation
Let x be the number of visits to the gym
and y be the total cost for plan one
So,
As each visit costs $3, x number of visits will cost 3x
One time fee is $50
So the equation can be written as:

Hence
Option 2:
is the right answer
