Answer: it c
Step-by-step explanation:
1.25 x 600= 750
1.50x 500=750
Since these are right triangles you can use the pythagorean theorem
a² + b² = c²
a = one leg of the triangle
b = the other leg of the triangle
c = the hypotenuse
1. 4² + 3² = c²
16 + 9 = c²
25 = c²
√25 = √c²
5 = c
c = 5cm
2. 5² + 12² = c²
25 + 144 = c²
169 = c²
√169 = √c²
13 = c
c = 13in
4. 7² + 9² = c²
49 + 81 = c²
130 = c²
√130 = √c²
11.4 = c
c = 11.4cm
5. a² + 10² = 15²
a² + 100 = 225
a² = 125
√a² = √125
a = 11.2ft
If A is 1/3 of B then A = 1/4 the sum of A and B. 1/4 times 48 = 12
Coin A = $12
Coin B = $48 - $12 = $36
(4x - y = 3) * 9
36x - 9y = 27
7x - 9y = -2
29x = 29
x = 1
y = 4*1 - 3
y = 1
X + y = 24
x - y = 2
Adding both equations
2x = 26
x = 13
y = 11
