Let's take a look at the triangles ABC and DCB
1. angles : B=C=90° because they are right triangles (AB perpendicular to BC and DC perpendicular to BC)
2. AC=BD (given)
3. BC is in common (the two triangles have it, you can say it like BC=BC)
So we proved that by SAS(side angle side), the triangles are congruent ABC= DCB
Since the triangles are congrueny, all their sides are equal so we can say that AB=DC
Sales tax on food = total cost of food x sales tax = $16 x 5.75% = $0.92
Bill after tax = total cost of food + sales tax on food = $16 + $0.92 = $16.92
Tip owned = total cost of food x tip in percent = $16 x 0.1 = $1.60
Total bill = bill after tax + tip owed = $16.92 + $1.60 = $18.52
Surface area=area around+2(cap)
area around =circumference times height=2*pi*6*15.1=569.257
caparea=circle area=pi*r^2=3.14*6^2=113.097
we need twice of that so 226.195
total surface area=569.257+226.195=795.451 square inches
answer is C
Answer:
You subtract the final temperature from the starting temperature to find the difference. So if something starts at 50 degrees Celsius and finishes at 75 degrees C, then the change in temperature is 75 degrees C – 50 degrees C = 25 degrees C. For decreases in temperature, the result is negative.
Step-by-step explanation: really not sure how to explain but in my understood thats my answer
