Answer: 42 (apex)
Step-by-step explanation:
![\\ \sf\Rrightarrow \dfrac{15}{20}=\dfrac{21}{28}](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5CRrightarrow%20%5Cdfrac%7B15%7D%7B20%7D%3D%5Cdfrac%7B21%7D%7B28%7D)
![\\ \sf\Rrightarrow \dfrac{1}{4}=\dfrac{1}{4}](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5CRrightarrow%20%5Cdfrac%7B1%7D%7B4%7D%3D%5Cdfrac%7B1%7D%7B4%7D)
Hence they are similar
#2
- <A=<H
- And ratio of sides are same
Hence both triangles are similar by SAS property
#3
![\\ \sf\Rrightarrow ∆KDH\sim ∆ABD](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5CRrightarrow%20%E2%88%86KDH%5Csim%20%E2%88%86ABD)
Answer:
21 is A and 23 is D
Step-by-step explanation:
Plug the numbers into the exponential growth formula:
![60100× (1+ \frac{x}{100}) ^{11}](https://tex.z-dn.net/?f=60100%C3%97%20%281%2B%20%5Cfrac%7Bx%7D%7B100%7D%29%20%5E%7B11%7D%20)
Now work backwards to get the answer:
1)Divide 120150 by 60100 to get 1.998668885
2) Find the 11th root of ANS:
![\sqrt[11]{1.998668885} =1.064976629](https://tex.z-dn.net/?f=%20%5Csqrt%5B11%5D%7B1.998668885%7D%20%3D1.064976629)
3) Minus 1 from your answer to give 0.064976629
4)Multiply your answer by 100 to give you the rate of x%, which is 6.5 to 1d.p
x=6.5 (1 d.p.)
Btw, this answer also works if you plug it back into the equation
