PLEASE HELP X= 8 9 10
1 answer:
Answer:
8
Step-by-step explanation:
This can be solved using intersecting chord theorem. This tells us that when 2 chords intersect inside a circle, the 4 segment it creates, each individual segments' products are equal.
Thus, we can say that the product of 5 and x is equal to the product of 10 and 4. Thus:
Hence x = 8 is the correct answer

<h3>What is right circular cone?</h3>
" A right circular cone is the 3 dimensional solid shape, which has an axis that is perpendicular to its circular base."
Formula used
Pythagoras theorem
(Hypotenuse)² = (adjacent side)² + (opposite side)²
According to the question,
Slant height 'l' of the cone = 13cm
height 'h' of the cone = 12cm
Let 'r' be the radius of the base of the cone.
As per the diagram,
InΔABC,
Apply Pythagoras theorem, we get
(l)² = (h)² +(r)²
Substitute the values of 'l' and 'h' in the formula we get,
(13)² =(12)² + (r)²
⇒ (r)² = 169 - 144
⇒ r =√25
⇒ r = 5cm
Hence, length of the radius of the cone is equals to 5 cm.

Answer:
<em>Sherita would need to make 10 free throws</em>
Step-by-step explanation:
<u>Proportions</u>
Sherita made 46 of her first 60 free throws in this basketball season. Calculating the average we get:
Sherita wants to have a free throw average of at least 80% in her next x free throws. This means she will have 46+x made throws out of 60+x total throws. For this new performance, the new average would be:
And we equate it to 80% (0.8 in decimal):
Multiplying by 60+x:
Operating:
Subtracting 46 and 0.8x:
0.2x=2
Dividing by 0.2
x = 10
Sherita would need to make 10 free throws
