Answer:
y = 90 meters.
Step-by-step explanation:
It is given in the figure that we have two triangles triangle A and triangle B are similar.
So,
.......... (1)
So, the ratio of the corresponding sides of two similar triangles remain same.
Now, x = 75 meters, n = 30 meters and m = 25 meters are given we have to find the value of y.
So, from relation (1), we have
⇒ y = 90 meters. (Answer)
Answer:
105ft^2
Step-by-step explanation:
1/2(21+14)*6
1/2(35)*6
17.5*6
105
Answer:
-9
Step-by-step explanation:
set y to 0
-2x + 1/2y = 18
-2x +1/2(0)=18
-2x / -2 = 18 /-2
x = -9
Answer:
180 pages
Step-by-step explanation:
Let
x = total number of pages
Monday + Tuesday + Wednesday
2/15x + 1/3x + 2/9x
= (6x+15x+10x)/45
= 31/45x
Thursday
x - 31/45x
= (45x-31x)/45
= 14/45x
3/4 of 14/45x
= 3/4 * 14/45x
= 42/180x
Total pages read = 31/45x + 42/180x
= (124x+42x)/180
= 166/180x
If he still has 14 pages left to read on Friday
Total read from Monday to Thursday + Friday
x = 166/180x + 14
x - 166/180x = 14
(180x-166x)/180 = 14
14/180x = 14
x = 14 ÷ 14/180
x = 14 × 180/14
x = 180 pages
