The present ages of Vijay and gautam are in ratio 2:3. five years hence,their ages will be in the ratio 3:4. find their present

Ratling [72]

Answer:

Vijay present age: a

Gautam present age : b

2/3=a/b

3a = 2b

3/4 = (a+5)/(b+5)

4a+20 = 3b +15

(3a - 2b =0) x 3---------9a - 6b = 0

(4a - 3b = -5) x 2------- 8a - 6b = -10

9a - 6b - 8a + 6b = 10

a = 10

3(10) - 2b =0

-2b = -30

b = 15

So

Vijay present age = 10

Gautam present age = 15

Bob, Bill, and Joe measured their heights. They figured out that the height of Bob is equal to b cm and he makes up 8/9 of the h

andrezito [222]

Answer:

Joe is 12 times taller than Bob

No the answer not rely on the meaning of b

Step-by-step explanation:

* Lets explain how the solve the problem

- The height of Bob is equal to b cm

- The height of Bob is 8/9 of the height of Bill

- Because 8/9 is less than one , then Bob is shorter than Bill

- The height of Bill makes up 3/32 of the height of Joe

* Lets write these information by mathematics relation

∵ The height of Bob is b

∵ The height of Bob is 8/9 height of Bill

∴ b = 8/9 the height of Bill

- Multiply both sides by 9

∴ 9 b = 8 the height of Bill

- Divide both sides by 8

∴ 9/8 b = the height of Bill

∴ The height of Bill is 9/8 b

∵ The height of Bill is 3/32 the height of Joe

∴ 9/8 b = 3/32 the height of Joe

- Multiply both sides by 32

∴ 36 b = 3 the height of Joe

- Divide both sides by 3

∴ 12 b = the height of Joe

∴ The height of Joe is 12 b

∵ b is the height of Bob

∴ The height of Joe is 12 times the height of Bob

∴ Joe is 12 times taller than Bob

- NO, the answer doesn't depend on b because the ratio between the

heights of Joe and Bob doesn't change by the change of b

IM OFFERING 100 POINTS, I NEED HELP AND ITS TIMED

Assoli18 [71]

Answer:

look below

Step-by-step explanation:

Part A: The y-intercept is $1,500

The x-intercept is 20 days

Part B: Equation of the line in point-slope form is y - 1350 = -75×(x - 2) Equation of the line in slope-intercept form is y = -75·x + 1500

Equation of the line in standard form is y + 75·x = 1500

Part C:

f(x) = -75·x + 1500

Part D: $1,125 Step-by-step explanation: The information given are; x, g(x) 0, $1,500 2, $1,350 4, $1,200 The equation of a straight line relation between the x, and y, coordinates in slope and intercept form is y = m·x + c Where; m = The slope c = The y-intercept From the data, we have two points, (x₁, y₁), (x₂, y₂) given as (0, 1,500), (2, 1350); The y-intercept = y at x = 0 = 1,500 y = -75·x + 1500 x = 1500/75 = 20
