If a is inversely proportional to x, a=15 when x=25 find the constant of variation, k

Mathematics

Answer:

Step-by-step explanation:

"Inversely proportional to x" in this situation is represented by a = k/x.

Find k:

Let a = 15 and x = 25, then calculate k:

15 = k/25)

Multiplying both sides by 25 yields k = 15(25), or k = 3/5

                       3

and so a = -----------

                      5x

mezya [45]

Answer:

a. \pi r^2h

b. \frac{4\pi r^2h}{5}

Step-by-step explanation:

Volume of the container denotes its quantity. It is a three-dimensional space.

Let V denotes the volume of the container, h denotes the height of the container and r denotes the radius of the container.

a.

The total capacity of the container in terms of π is \pi r^2h<u />

b.

As the cylindrical container is four-fifths full of powder, so the volume of the powder in terms of π is \frac{4}{5}\times volume of the container i.e., \frac{4\pi r^2h}{5}

The mean age of Mr Jasmi,Miss Haslinda and their three children is 38 years. The mean age of their three children is 18 years. C
DedPeter [7]
Answer: 68

Explanation:

Let x be the age of Mr Jasmi
y be the age of Miss Haslinda
a + b + c be the age of the 3 children

We can write:
(x + y + a + b + c)/5 = 38

But:
(a + b + c)/3 = 18
a + b + c = 18(3)
a + b + c = 54

Substitute this value to our first equation

(x + y + 54)/5 = 38
x + y + 54 = 38(5)
x + y + 54 = 190
x + y = 190 - 54
x + y = 136

Thus:
Mean age of (mr jasmi and miss Linda) = (x+y)/2

But x + y = 136

=> mean age = 136/2 = 68

How do you do this??
astra-53 [7]

welll...you have there written just one relationship...it is berween 280 and 4 hours...you have to figure out speed:

280 \div 4 = 70

it is speed per hour

then you just connect time and speed:

  1. 140 - 2
  2. 280 - 4
  3. 350 - 5
  4. 420 - 6
  5. 560 - 8
  6. 700 - 10
