So when you add mixed numbers, you must convert it into fractions. The four would become part of the fraction and be 43/10 and the six becomes part of the fraction which is 69/10. You can find this by multiplying 4 by the denominator and then adding it to the numerator (4 Times 10 = 40 + 3 = 43/10) and same for the other one. The answer is 112/10, simplify to 11 1/5.
Answer: 9
because you need to first use the ones in the parentheses and then move on.
Answer:
Step-by-step explanation:
the formula for a circle which would be C = 2 \pi r
The 9.5*3.14 divide by two so 14.915
and this rounded would be 15.0 or 14.9 not too sure just pick whatever
Answer:
1. the y-intercept is 9.5 and it means the starting length of the candle
2. the slope is -1/2 and it means that the candle burns 1/2 an inch every hour
3. it burns an inch every 2 hours, it is 9.5 inches long, so 19 hours it'll take to burn.
False
because tan^2 45 = 1^2 = 1
and sec^2 x = 1/ cos^2 45 = (sqrt2)^2 = 2
so the sum = 3
