Answer:
Step-by-step explanation:
sin 45 = x/12
x = 12 sin 45
x = 6√(2)
answer is D
<span>The correct answer is: 21
Explanation:
Let's first assume few variables!
x = Ishann's age (in years)
y = Christopher's age (in years)
1. Ishann is 3 times as old as Christopher can be represented mathematically as:
x = 3y ---- (1)
2. Ishann is 14 years older than Christopher can be represented mathematically as:
x = y + 14 ---- (2)
Get the value of y from Equation (1) and plug it in Equation (2):
(2) => x = (x/3) + 14
3x = x + 42
2x = 42
x = 21
Hence Ishann is 21 years old!</span>
A) 500g=$12 -> 100g=12:5 100g=$2,40
20g=2,40:5=$0,58
320g=3x2,40+0,58
320g=7,20+0,58
320g=7,78$
(311&1/4-186&3/4)/(5-3)=62&1/4
so the difference between each adjacent number is 62&1/4
when the top number is 4, the bottom number is 186&3/4+62&1/4=249 (a)
when the top number is 4, the bottom number is 311&1/4+62&1/4=373&1/2 (b)
C=10
