Answer:

x = 30

Step-by-step explanation:

\frac{3}{5}(30) + \frac{1}{3}(30) = 28

\frac{3}{5}(30) = 18

\frac{1}{3}(30) = 10

18 + 10 = 28

\frac{3}{8} x +  \frac{1}{3} x = 28

\frac{9}{24} x +  \frac{8}{24}x  = 28

\frac{17}{24} x = 28

x = 28 \div  \frac{17}{24}

x = 28 \times  \frac{24}{17}

x =  \frac{672}{17}

Answer : 672/17

Suppose F⃗ (x,y)=4yi⃗ +2xyj⃗ . Use Green's Theorem to calculate the circulation of F⃗ around the perimeter of a circle C of radi
Juliette [100K]

Answer:

-9π

Step-by-step explanation:

∫c (4y dx + 2xy dy)

= ∫∫ [(∂/∂x)(2xy) - (∂/∂y)(4y)] dA, by Green's Theorem

= ∫∫ (2y - 4) dA

Now convert to polar coordinates:

∫(r = 0 to 3) ∫(θ = 0 to 2π) (2r sin θ - 4) * (r dθ dr) --- first integration

= ∫(r = 0 to 3) (-2r cos θ - 4θ) * r {for θ = 0 to 2π} dr

= ∫(r = 0 to 3) -2πr dr

= -πr² {for r = 0 to 3}

= -π(3²) - -π(0)²

= -9π

A unicorn’s favorite food is marshmallows. They can find other food resources, but marshmallows are their absolute favorite. Usi
Tpy6a [65]

Answer:

69813.33 marshmallow

the calories required (i.e 10,920,800 ) is greater than the energy provided (i.e 7,500,000) hence the 2 unicorns cannot survive

Step-by-step explanation:

Given:

Unicorn weights = 440 kg

Marshmallow weighs = 0.5 grams

Unicorn needs = 34 calories/kg of body weight/day

Marshmallow offers = 3 calories/gram

Calories required by Unicorn in a week

= Calories needed × Weight of unicorn × Total days in a week

= 34 × 440 × 7

= 104,720 calories

Now,

Marshmallows required = \frac{\textup{Calories required}}{\textup{Energy offered by marshmallow}}

= \frac{\textup{104,720}}{\textup{3}}

= 34906.67 grams

Therefore,

the number of marshmallows required = \frac{\textup{Mass of marshmallow required}}{\textup{Mass of marshmallow}}

= \frac{\textup{34906.67}}{\textup{0.5}}

= 69813.33 marshmallow

b) Total calories provided by the marshmallow

= 5,000,000 × 0.5 × 3

= 7,500,000 calories

and,

calories required by 2 unicorns in an year

= weight of 2 unicorn × calories needed × number of days in an year

= 2 × 440 × 34 × 365

= 10,920,800

Since,

the calories required (i.e 10,920,800 ) is greater than the energy provided (i.e 7,500,000) hence the 2 unicorns cannot survive
