Answer:
37
Step-by-step explanation:
-3 ^2 = 9
9 * 5 = 45
45 - 8 = 37
Answer:
The Ration of length 2.0 meters to the length 1.2 meters = 5 : 3
Step-by-step explanation:
The given two length are 2.0 m and 1.2 m
Length L1 = 2.0 m And
Length L2 = 1.2 m
SO, The ratio of L1 : L2 = ![\frac{2.0}{1.2}](https://tex.z-dn.net/?f=%5Cfrac%7B2.0%7D%7B1.2%7D)
Or, The ratio of L1 : L2 = ![\frac{20}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B20%7D%7B12%7D)
∴ The ratio of L1 : L2 = ![\frac{5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B3%7D)
Hence The ratio of L1 : L2 is 5 : 3 Answer
Answer:
5x + 8y = 24
Step-by-step explanation:
Multiply the equation 8
8 ( y = -5x/8 + 3 )
8y = -5x + 24
5x + 8y = 24
Answer:
it will take 8 minutes
Step-by-step explanation:
Here, we want to
calculate the amount of time taken to fill the tank given the total amount of water in the tank.
Mathematically, the formula go
use is ;
w= 100 + 55t
540 = 100 + 55t
55t = 540-100
55t = 440
t = 440/55
t = 8
Answer:
HK = 20
Step-by-step explanation:
LM = (1/2) HK {Mid point theorem}
![10x - 90 = \frac{1}{2}(10x - 80) \\](https://tex.z-dn.net/?f=10x%20-%2090%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2810x%20-%2080%29%20%5C%5C)
2*(10x - 90) = 10x - 80
2*10x - 2*90 = 10x - 80
20x - 180 = 10x - 80 {add 180 to both sides}
20x = 10x - 80 + 180
20x = 10x +100 {Subtract 10x from both sides from }
20x -10x = 100
10x = 100
x = 100/10
x = 10
HK = 10x - 80
= 10*10 - 80
= 100 - 80
= 20
