Answer:
Kami sold 28 large figurines
Step-by-step explanation:
L = number of large figurines
S = number of small figurines
L+S = 70 since he sold 70 figurines
12L = 8S since the amount of money collected for the large figurines is equal to the amount of money for the small figurines
L+S = 70
12L = 8S
Divide by 8
12/8 L = S
3/2 L = S
Substitute this into the first equation
L+S = 70
L + 3/2 L = 70
Get a common denominator
2/2 L + 3/2L = 70
5/2 L = 70
Multiply each side by 2/5
2/5 * 5/2 L = 70 * 2/5
L = 28

Answer:
c = 75 in
Step-by-step explanation:
The hypotenuse of a right triangle is found by the Pythagorean theorem:
<em>a² + b² = c²</em> (a and b are the legs, c is the hypotenuse)
Plug in: <em>45² + 60² = c²</em>
Square + square root: √(2025 + 3600) = c
Add: √5625 = c
Square root: 75 in = c (no negatives because we are finding distance)
