Step-by-step explanation:
Yes they are congruent by SSS
AB = AC because triangle ABC is isosceles
BD = CD because triangle BDC is isosceles
AD is common to both triangles
conguent by SSS
Answer:
6 3/4 (six and three fourths)
Step-by-step explanation:
First, we must turn 4 6/7 into an improper fraction, AKA 28/7. Now, you can't subtract 1/4 from 28/7, can you? So what you need to do is find the greatest common factor of 4 and 7. The GCF would be 28 (7 x 4 = 28, 4 x 7 = 28).
Now we know that the GCF is 28, we can turn the numbers into 28/28 and 1/28. But wait! We aren't done yet. Now we have to change the numerators. Since you multiplied the denominator (7) by 4 to get 28, you must now multiply 28 by 4 as well. (If you do something to the bottom, you have to do it to the top!) Because of this, we are now at 196/28.
Next, we must do the numerator of 1/28. Since we multiplied the denominator (4) by 7 to get 28, we must now multiply 1 by 7. This gets you to 7/28.
It's finally time to subtract. 196 - 7 is 184, so we are at 184/28. But hey, that's an improper fraction! You have to simplify. 184 divided by 28 is 6.75. 0.75 is 3/4 when turned into a fraction.
Mash 6 and 3/4 together, and you've got your answer! 6 3/4.
The formula is
A=p (1+r/k)^kt
A future value 10000
P present value 6000
R interest rate 0.0375
K compounded every two months 6
T time?
We need to solve for t
T= [log (A/p)÷log (1+r/k)]÷k
T=(log(10,000÷6,000)÷log(1+0.0375÷6))÷6
T=13.7 years
Round your answer to get
T=14 years
