Answer:
1. Yes (side angle side)
2. I don’t know for sure but I’m thinking no
3. No
Step-by-step explanation:
Sounds like your describing complementary angles (a pair of angles that add up to be 90 degrees) but not super sure based on that description you have there.
Tell me does it look like this:
Answer:
8.75

Hope I helped
Ok lets see if i can explain this properly. sorry it's long but i had to explain it properly
A) to calculate the final value received at the end of a period of time when the percentage is known we divide the percentage by 100 to give it to us as a decimal ( lets call this "X". this value is then added to 1 to give 1+X.
1+X is then put to the power of the period of time passed. in this case 3. so this gives us 1+X to the power of 3.
the initial value is then multiplied by 1+X to the power of three to give the value of the final answer.
so the equation used is final value = initial value * (1+X)^3
to give us the percentage we rearrange the equation to give us.
<u />x= (cube root of, final value/initial value) -1
= (cube root of, 42830/42000) -1
=0.0065 to two sig figs
as mentioned before to find X we divide the interest rate by 100. so to find the interest rate here we must multiply X by 100
=0.65%
B) 6%/ 100 = 0.06
0.06+1=1.06
1.06^4=1.263 to 3 decimal places
1.263*42000=53046
yes pablo will have 50000 at the end of the 4 years
