Answer:
2 - x^2
Step-by-step explanation:
Answer:sinA=8/17
Step-by-step explanation:
Using Pythagoras principle
x=√(15^2+8^2)
x=√(15x15+8x8)
x=√(225+64)
x=√(289)
x=17
SinA=opposite/hypothenus
SinA=8/17
Answer:
Henry still has to mow 75% of the laws.
Step-by-step explanation:
It is given that Henry has 15 lawns mowed out of a total of 60 lawns.
We need to find: What percent of the lawns do Henry still have to mow?
Henry has 60 lawns in total.
He mowed 15 out of them.
The percentage of lawns mow = ![\frac{15}{60} \times 100=25 \%](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B60%7D%20%5Ctimes%20100%3D25%20%5C%25)
Henry mowed 25% of total lawns.
The percent of laws still have to mow = 100%-25%
The percent of laws still have to mow = 75%
Hence, Henry still has to mow 75% of the laws.
Answer:
x=4
Step-by-step explanation:
Hey There!
So if DE is the midsegment then to find x you divide the length of AE by 2
8/2=4
Therefore x=4
Answer:
![q=8.5](https://tex.z-dn.net/?f=q%3D8.5)
Step-by-step explanation:
The ratio of the side lengths (AB) and (BC) is given. One is also given an expression for the side lengths of each of these sides. Set up a proportion to describe this scenario, then solve using cross products;
![\frac{AB}{BC}=\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BBC%7D%3D%5Cfrac%7B3%7D%7B4%7D)
Substitute,
![\frac{60}{10q+15}=\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B60%7D%7B10q%2B15%7D%3D%5Cfrac%7B3%7D%7B4%7D)
Cross products,
![\frac{60}{10q+15}=\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B60%7D%7B10q%2B15%7D%3D%5Cfrac%7B3%7D%7B4%7D)
![(60)(4)=(10q+15)(3)\\\\240=30q+45](https://tex.z-dn.net/?f=%2860%29%284%29%3D%2810q%2B15%29%283%29%5C%5C%5C%5C240%3D30q%2B45)
Inverse operations,
![240=30q+45\\\\195=30q\\\\8.5=q](https://tex.z-dn.net/?f=240%3D30q%2B45%5C%5C%5C%5C195%3D30q%5C%5C%5C%5C8.5%3Dq)
