Answer:

<u>Option D : c =200t</u>

Step-by-step explanation:

The number of calories burned C varies directly with the time spent exercising T

∴  ∝ t

∴ c = a t

Where a is the constant of proportion

exercising for 4 hours he burns 800 calories

∴ c = 800 when t = 4

∴ 800 = 4 a

∴ a = 800/4 = 200

∴ c = 200 t

<u>The answer is option D : c =200t</u>

How many solutions does the equation 3x − 7 = 4 + 6 + 4x have
Sunny_sXe [5.5K]

Answer:

The given equation 3x − 7 = 4 + 6 + 4x has one solution.

Step-by-step explanation:

Given : Equation 3x − 7 = 4 + 6 + 4x

We have to find the number of solutions of the given equation.

Consider the given equation 3x − 7 = 4 + 6 + 4x

Simplify, we have,

3x − 7 = 10 + 4x

Now subtract 3x both side, we hvae,

-7 = 10 + 4x - 3x

Simplify, we have,

- 7 = 10 + x

Subtract 10 both side, we have,

-7 - 10 = x

x = - 17

Thus, The given equation 3x − 7 = 4 + 6 + 4x has one solution.

Please hurry I will mark you brainliest.
ivann1987 [24]

Answer:

12862.83cm³

Step-by-step explanation:

Volume of the Box: [L×W×H] or [30x30x30] or [27000cm³]

Volume of the Sphere: [\frac{4}{3}\pi r^{3}] (\pi=pi=3.14) (r=radius=15) or [\frac{4}{3}×3.14×3375] or [14137.17cm³]

Volume of the empty space: 27000cm³-14137.17cm³=12862.83cm³

Btw there are online tools to help you find the volume of a sphere (just use it after you understand the equation)

Hope I helped!
