One number is 3/8 of another number. The difference of the two numbers is 4.2. What is the lesser number
boyakko [2]

Answer:

2.52.

Step-by-step explanation:

If one number is x then the other = 3x/8.

Also x - 3x / 8 = 4.2

x - 0.375 x = 4.2

0.625x = 4.2

x = 4.2 / 0.625

x = 6.72.

So the lesser number is 6.72 * 0.375 = 2.52.

Can someone please help me real quick?
Dima020 [189]

Answer:

3.5p ≤ 40

Step-by-step explanation:

The inequality that best describes this problem is 3.5p ≤ 40;

Given parameters:

Total amount with me = $40

Cost per package of hot dog  = $3.5

Unknown;

The inequality that represents the problem  = ?

Solution:

p is the number of hotdogs that can be bought.

  So, total hotdog that can be bought if each hotdog cost $3.5 per box is;

                    p x 3.5

Now,

    this will equal the total amount at hand;

       p x 3.5 ≤ 40

         3.5p ≤ 40

Pls help
KATRIN_1 [288]

Answer:

169.04 in² (nearest hundredth)

Step-by-step explanation:

Surface area of a cone = \pir² + \pirl

(where r = radius of the base and l = slant height)

Given slant height l = 10 and surface area = 188.5

Surface area  = \pir² + \pirl

188.5 = \pir² + 10\pir

\pir² + 10\pir - 188.5 = 0

r = \frac{-10\pi +\sqrt{(10\pi )^2-(4\times\pi \times-188.5)} }{2\pi } = 4.219621117...

Volume of a cone = (1/3)\pir²h

(where r = radius of the base and h = height)

We need to find an expression for h in terms of l using Pythagoras' Theorem a² + b² = c², where a = radius, b = height and c = slant height

r² + h² = l²

h² = l² - r²

h = √(l² - r²)

Therefore, substituting found expression for h:

volume of a cone = (1/3)\pir²√(l² - r²)

Given slant height l = 10 and r = 4.219621117...

volume = 169.0431969... = 169.04 in² (nearest hundredth)
