Answer:
= 18.857 cm²
Step-by-step explanation:
The area of a segment is given by;
θ/360 × 2πr². where θ is the angle subtended by the arc to the center of the circle and r is the radius of the circle.
θ = 60, and r = 6
Therefore;
Area = 60/360 × 22/7 × 6²
= 18.857 cm²

By calculation, deduce whether triangle ABC is a right-angled triangle
Answer:
ΔABC is not a right- angled triangle
Step-by-step explanation:
Given AB = 8, BC = 5
Then AC = 22 - (8 + 5) = 22 - 13 = 9 cm
Using the converse of Pythagoras' identity
If the square of the longest side equals the sum of the squares of the other 2 sides then triangle is right.
AC² = 9² = 81
AB² + BC² = 8² + 5² = 64 + 25 = 89
81 ≠ 89, hence ΔABC is not right- angled
The weight that can be added more to the truck before it exceeds the weight limit for the bridge is 1250 pounds.
Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.
The process of doing addition is also called as finding the sum.
Given that,
Weight of the cargo truck = 8,750 pounds
Weight limit for the given bridge = 5 tons
We have the conversion factor,
1 ton = 2000 pounds
5 tons = 5 × 2000 = 10,000 pounds
Already there is a weight of 8,750 pounds for the truck.
We can add the weight such that the sum equals 10,000.
x + 8750 = 10,000
x = 10,000 - 8750
x = 1250 pounds
Hence the additional weight that can be added is 1250 pounds.

12/√7+2
Answer:
The answer is 4√7 - 8
Step-by-step explanation:
12/√7+2
Rationalize the denominator
=12/7+2 * √7-2/√7-2
=12√7-24/7-4
=12√7-24/3
By taking common from numerator we get
=12(√7-2)/3
=4√7-8
Answer:
The answer is 4√7 - 8
