Answer:221
Step-by-step explanation:20+201=221
Answer:
New price = $210
Step-by-step explanation:
Given:
Original price = $120
Increase in cost = 75%
Find:
New price
Computation:
New price = Original price + Increase in cost
New price = 120 + 120(75%)
New price = 120 + 90
New price = $210
The image is a bit hard to make out, so I'm going to make some guesses. It looks like it says
![PN=12](https://tex.z-dn.net/?f=PN%3D12)
,
![QP=8](https://tex.z-dn.net/?f=QP%3D8)
, and
![PM=17](https://tex.z-dn.net/?f=PM%3D17)
, and you're asked to find
![QR](https://tex.z-dn.net/?f=QR)
.
You know that
![\Delta NPM](https://tex.z-dn.net/?f=%5CDelta%20NPM)
and
![\Delta NQR](https://tex.z-dn.net/?f=%5CDelta%20NQR)
are similar, which means their corresponding sides are proportional in length. So there's some constant
![c](https://tex.z-dn.net/?f=c)
such that
![NP=cNQ](https://tex.z-dn.net/?f=NP%3DcNQ)
![PM=cQR](https://tex.z-dn.net/?f=PM%3DcQR)
![MN=cRN](https://tex.z-dn.net/?f=MN%3DcRN)
To find
![QR](https://tex.z-dn.net/?f=QR)
, you need to know
![PM](https://tex.z-dn.net/?f=PM)
and the constant
![c](https://tex.z-dn.net/?f=c)
.
Clearly,
![NQ=NP+PQ=12+8=20](https://tex.z-dn.net/?f=NQ%3DNP%2BPQ%3D12%2B8%3D20)
. So, the first equation becomes
![NP=cNQ\iff12=20c\implies c=\dfrac{12}{20}=\dfrac35](https://tex.z-dn.net/?f=NP%3DcNQ%5Ciff12%3D20c%5Cimplies%20c%3D%5Cdfrac%7B12%7D%7B20%7D%3D%5Cdfrac35)
Then in the second equation, you have
Answer:
no 2 should be 19
Step-by-step explanation:
maximum high temp is the highest he temperature went therefore its 19
15x5 is the answer because if you multiply 15 and 5 you get 75.
