Answer:
A. triangle 4 and triangle 3.
Step-by-step explanation:
If you look at triangle 4, you can see that it need to be rotated and reflected.
If you look at triangle 3, you can see that it needs to be reflected.
Use arithmetic sequence in order to get to answer:
a_n= a₁ rⁿ⁻¹
r is a common ratio, a₁ is the first term and a_n is the summation.
a_n= 1 (2/1)¹⁵⁻¹= 16384 pennies
Answer:
Step-by-step explanation:
10
the answer is 10
2/2, 4/4, 5/5, 7/7, or any fraction with the same numerator and denominator will be equivalent. All fractions equal 1.
Answer:
c = 20 inches
Step-by-step explanation:
To find the sides of a right triangle, you use the Pythagorean Theorem.
a² + b² = c²
You know a and b, and you need to find c, the hypotenuse.
Plug in a and b.
(12)² + (16)² = c²
Simplify by solving the exponents.
144 + 256 = c²
Combine the constants.
400 = c²
Take the square root of both sides.
√400 = √c²
Solve the √
±20 = c
The length cannot be negative, so you can eliminate that as an option.
So, c = 20
