Answer:
AD is Congruent to BC and it's given, (given just means that it was already said or stated, and you don't need to do the work to find it) Angle DAC would be congruent to angle BAC (if that doesn't work, rearrange them to look like angle CAB). AC would be congruent to DB. Triangle ADC would be congruent to triangle BCD by (since i don't know exactly which way the letters are arranged is would either be SAS or SSA) and that's because you know two of the sides are congruent to each other and one angle.
I tried hard to sketch out what the shape looked like based on the information given, and that's because I need a visual of what the shape looks like. Sorry, this took so long to answer.
Answer:
First one is 25/2
Step-by-step explanation:
12×2+1=25/2
9×4+1=36/4
cross multiply and you get
100/
divide both by 2 and you get 50/4 then you divide both by 2 again and you get 25/2 because you can't reduce it anymore
when a=4 and b=3,
3.14((4 x 2)+ (4 x 3)) = 3.14(8+12) = 3.14 x 20 = 62.8
Answer: the area of the whole shape is 0.77. hope this helped.
Step-by-step explanation:
The money was paid at an annual interest of 261.42%
Explanation:
- The initial amount of the guitar when it was loaned was $960. After a month the guitar cost $1,170. This means that in one month the price went from $960 to $1,170. Increase in cost = Difference between two costs = $1,170 - $960 = $210.
- To convert this into a percent we divide the difference in value by the original price and multiply the answer with 100 to convert it into a percentage. % increase in cost = difference between two costs / original cost % increase in cost = ($210 / $960) * 100 = 0.21785 * 100 = 21.785%
- This 21.875% was the monthly interest that was paid. To convert it into annual interest rate we multiply it with the 12 months.
- Annual interest rate = monthly interest rate * 12 = 21.785% * 12 = 261.42%. This means if the guitar was loaned for a year, you would have to pay $3469.44.
