A 40-meter-long blade of a wind turbine makes one complete revolution in 10 seconds. To the nearest tenth, the linear velocity of the blade is meters per second.

Answers

Answer 1

Answer:

25.13 m/s

Step-by-step explanation:

Linear velocity = Distance / time

The distance = Circumference of turbine = 2πr

Radius, r = 40 m

Circumference= 2 * π * 40 = 251.327

The linear velocity is thus :

Circumference / time

= 251.327m / 10s

= 25.13 m/s

The cereal box has a volume of 432 in if the base has dimensions of 2 in by 12 in what is the height of the box

Answers

Answer:

Height of the cereal box = 18 in.

Step-by-step explanation:

A cereal box is in the shape of a cuboid.

And volume of a cuboid is represented by the expression,

Volume = Length × Width × Height

It's  given that volume of the box = 432 in³

Length of the base = 2 in.

Width of the base = 12 in

By substituting these values in the expression,

432 = 2 × 12 × h

h = [tex]\frac{432}{24}[/tex]

h = 18 in.

Therefore, height of the cereal box is 18 in.

Pato's current age is represented by [tex]a[/tex].

To find:

The equation that could be used to correctly solve for [tex]a[/tex].

Solution:

We know that, Pato's current age is represented by a, then

Yamir's age = [tex]2a[/tex]

After three years,

Pato's age = [tex]a+3[/tex]

Yamir's age = [tex]2a+3[/tex]

In three years, the sum of their ages will be 30.

[tex](a+3)+(2a+3)=30[/tex]

need help with working perimeter and area please

Answers

Answer:

Area = 228 m²

Perimeter = 60 m

Step-by-step explanation:

The figure given shows a rectangle that has a cut triangular portion.

✔️Area of the figure = area of rectangle - area of the triangular cut portion

= L*W + ½*bh

Where,

L = 20 m

W = 12 m

b = 20 - (8 + 8) = 4 m

h = 6 m

Plug in the values

Area = 20*12 - ½*4*6

Area = 240 - 12

Area = 228 m²

✔️Perimeter = perimeter of rectangle - base of the triangular cut portion

= 2(L + W) - b

L = 20 m

W = 12 m

b = b = 20 - (8 + 8) = 4 m

Plug in the values

Perimeter = 2(20 + 12) - 4

= 2(32) - 4

= 64 - 4

Perimeter = 60 m

the profit a company earns every month depends

Answers

Answer:

The profit that a company earns each month depend on the amount of product sold, p, for $855 each and the amount of money spent on rent, utilities, and other expenses, which always totals to $6,780. The CEO earns 15% of the profit.

ncome: p*855

Expenses: 6780

Profit = Income - expenses = 855p - 6780 = 855*250 - 6780 = 213750 - 6780 = 206970

CEO's earn = 15% * 206970 = 0.15*206970 = 31,045.5

Binaya spent 9/10 of his pocket money. He has Rs 120 left now. Find:. (i) how much money did he spend ? (ii) how much money did he have?​

Answers

Solving a linear equation we will find that they spent a total of Rs 1.080 and they initially had Rs 1,200.

How much money did he spend?

Let's assume that initially they had M money, we know that they spend 9/10 of it, so now they have:

(1/10)*M

And we also know that at the end Binaya had Rs 120, so we can write the linear equation:

(1/10)*M = Rs 120

Solving that for M we will get:

M = 10*Rs 120

M = Rs 1,200

And the amount that they spent is 9/10 of that, so it is:

(9/10)* Rs 1,200 = Rs 1,080

So, they spent a total of  Rs 1,080 and they initially had a total of Rs 1,200

h(x) = x ^ 2 - 7x - 8 1) What are the zeros of the function? Write the smaller first, and the larger second smaller I largerx = 2 ) What is the vertex of the parabola ?

Answers

Answer:

The zeros are x = -1 and x = 8

The vertex is (3.5, -20.25)

Step-by-step explanation:

When we have a quadratic equation like:

y = a*x^2 + b*x + c

The zeros of the function are the values of x such that:

a*x^2 + b*x + c = 0

And the solutions are given by the Bhaskara's equation, which is:

[tex]x = \frac{-b \pm \sqrt{b^2 - 4*a*c} }{2*a}[/tex]

And the vertex is at:

x = -b/2a

The y-value at the vertex is the function evaluated in that point.

In this case, we have the equation:

h(x) = x^2 - 7*x - 8

Then:

a = 1

b = -7

c= -8

Replacing these in the Bhaskara's equation we get:

[tex]x = \frac{-(-7) \pm \sqrt{(-7)^2-4*1*(-8)} }{2*1} = \frac{7 \pm 9 }{2}[/tex]

Then the two solutions are:

x = (7 - 9)/2 = -2/2 = -1   (this is the smaller one)

and

x = (7 + 9)/2 = 16/2 = 8  (this is the larger one)

And we will have the vertex at:

x = -(-7)/2*1 = 7/2 = 3.5

Evaluating h(x) in 3.5 we get:

h(3.5) = (3.5)^2 - 7*(3.5) - 8 = -20.25

Then the vertex is the point:

(3.5, -20.25)

Hasina starts first. The equations show the distance
each girl is from home m minutes after Jada starts.
What is the solution of the system of equations? What
does this mean in this situation?
Hasina: d = 300m + 1,500
Jada: d= 300m

Answers

The solution to the system of equations is d = 300m, which means that after Jada starts, both Hasina and Jada will be 300m away from home.

The solution to the system of equations is d = 300m. This means that after Jada starts, both Hasina and Jada will be 300m away from home. This is because the equation for Hasina states that she is 300m + 1500m away from home. Since Jada is starting second, she will only be traveling 300m from home. Therefore, the solution of the system of equations is d = 300m.

To solve the system of equations, we can use substitution. First, we can substitute 300m for d in Jada's equation. This gives us 300m = 300m, which is a true statement. We can then substitute this value for d in Hasina's equation, which gives us 300m + 1500m = 300m. To solve for m, we can subtract 1500m from both sides, giving us 0 = -1500m. To isolate m on one side, we can divide both sides by -1500, giving us -1 = m. This means that after Jada starts, both Hasina and Jada are 300m away from home.
