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)
Answer:
21.67.
Step-by-step explanation:
Here is the correct question: Lois made a dish with 4 1/3 cups of pasta. One serving of the pasta is 0.2 cups. How many servings of pasta were in the dish Lois made?
Given: Lois made dish with
One serving of pasta= 0.2 cups
Now, using unitary method to find total number of servings of pasta were in the dish Lois made.
First, lets convert into decimal
= 4.33 cups
∴ Lois made a dish with 4.33 cups of pasta.
We know, One serving of pasta= 0.2 cups
∴ Total serving in 4.33 cups of pasta=
∴ 21.67 serving is possible in of pasta.
