Answer:
1480 feet
Step-by-step explanation:
180yd x 2 = 360yd
change to feet: 360 x 3 = 1080 feet
200ft x 2 = 400ft
1080 + 400 = 1480ft
Answer:
y =47.5.
Step-by-step explanation:
First eliminate the fractions by multiplying through by the LCM of 7 and 3 which is 21:
21* 6[y-2]/7-21*12 = 21*2[y-7]/3
18(y - 2) - 252 = 14(y - 7)
18y -36 - 252 = 14y - 98
18y - 14y = -98 + 36 + 252
4y = 190
y = 190/4
y = 47.5.
Answer:
t α 1 /r ; t = k/r
Step-by-step explanation:
Given that :
Time taken, t varies inverse as rate, r
MATHEMATICALLY,
t α 1 /r
Hence,
t = k/r ;
Where, k is the proportionality constant
Hence, the situation could be expressed as :
t = k/r OR
t α 1 /r

Answer:
![\frac{y-2}{4}](https://tex.z-dn.net/?f=%5Cfrac%7By-2%7D%7B4%7D)
Step-by-step explanation:
Let's start by factoring everything:
![\dfrac{\frac{y^2+y}{y^2-2y}}{\frac{4y+4}{y^2-4y+4}}=](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cfrac%7By%5E2%2By%7D%7By%5E2-2y%7D%7D%7B%5Cfrac%7B4y%2B4%7D%7By%5E2-4y%2B4%7D%7D%3D)
![\dfrac{\frac{y(y+1)}{y(y-2)}}{\frac{4(y+1)}{(y-2)^2}}=](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cfrac%7By%28y%2B1%29%7D%7By%28y-2%29%7D%7D%7B%5Cfrac%7B4%28y%2B1%29%7D%7B%28y-2%29%5E2%7D%7D%3D)
Now, you can cancel out some terms:
![\dfrac{\frac{y+1}{y-2}}{\frac{4(y+1)}{(y-2)^2}}=](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Cfrac%7By%2B1%7D%7By-2%7D%7D%7B%5Cfrac%7B4%28y%2B1%29%7D%7B%28y-2%29%5E2%7D%7D%3D)
Now, when you divide a fraction by another fraction, that is the same as multiplying the first fraction by the reciprocal of the second one:
![\frac{y+1}{y-2}\cdot \frac{(y-2)^2)}{4(y+1)}=](https://tex.z-dn.net/?f=%5Cfrac%7By%2B1%7D%7By-2%7D%5Ccdot%20%5Cfrac%7B%28y-2%29%5E2%29%7D%7B4%28y%2B1%29%7D%3D)
![\frac{y-2}{4}](https://tex.z-dn.net/?f=%5Cfrac%7By-2%7D%7B4%7D)
Hope this helps!
