Answer:

Step-by-step explanation:

8 out of 40 people is a ratio of 20 %

32 out of 40 people is a ratio of 80%

Therefore it would be 32 people are males. :D

Initially a wheel rotating about a fixed axis at a constant angular deceleration of 0.5 rad/s 2 has an angular velocity of 0 rad

Zigmanuir [339]

Answer:

$\theta = 5.83\ rad$

Step-by-step explanation:

given,

angular deceleration, α = -0.5 rad/s²

final angular velocity,ω_f = 0 rad/s

angular position, θ = 6.1 rad

angular position at 3.9 s = ?

now, Calculating the initial angular speed

$\omega_f^2 = \omega_i^2 + 2 \alpha \theta$

$0 = \omega_i^2 - 2\times 0.5\times 6.1$

$\omega_i = \sqrt{6.1}$

$\omega_i = 2.47\ rad/s$

now, angular position calculation at t=3.9 s

$\theta = \omega_i t + \dfrac{1}{2}\alpha t^2$

$\theta =2.47\times 3.9 - \dfrac{1}{2}\times 0.5\times 3.9^2$

$\theta = 5.83\ rad$

Hence, the angular position of the wheel after 3.9 s is equal to 5.83 rad.

Your coffee bar has two kinds of drink One cup of the first one costs 9 grams of juice , 4 grams of coffee and 3 grams of sugar

VMariaS [17]

Answer:

How many drinks should be sold to get a maximal profit? 468

Sales of the first one = 345 cups

Sales of the second one = 123 cups

Step-by-step explanation:

maximize 1.2F + 0.7S

where:

F = first type of drink

S = second type of drink

constraints:

sugar ⇒ 3F + 10S ≤ 3000

juice ⇒ 9F + 4S ≤ 3600

coffee ⇒ 4F + 5S ≤ 2000

using solver the maximum profit is $500.10

and the optimal solution is 345F + 123S

There are 158 birds on the endangered species list in some year. this is 16 more than twice the number of reptiles on the list.

S_A_V [24]

Let the number of reptiles on endangered list be 'x'

2x + 16=158

2x=158-16

2x=142

x=71

So there are 71 reptiles on the endangered list
