Step-by-step explanation:

Answer:

Approximately 0.11 acres can be planted with one pound of seed

Step-by-step explanation:

You use the rule of 3

66 pounds / 7 acres = ? pounds / 1 acre

? = 66 x 1 ÷ 7

? = 66 ÷ 7

? ≈ 9.23 pounds / acre

Now you know how many pounds you have for 1 acre. You reuse the formula from before

9.23 pounds / 1 acre = 1 pound/ ? acres

? = 1x1 ÷ 9.23

? = 1 ÷ 9.23

? = 0.11 acres/pound

Verify the answer:

0.11 x 9.23 ≈ 9.33, which is approximately 1 pound

Answer:

90 pounds per acre

Answer:

The answer is Dun Dun Duuun 3 {x/4} - 1/2{x/10}

The expression equivalent to 70% of x is,

⇒ 3 (StartFraction x Over 4 EndFraction) minus one-half (StartFraction x Over 10 EndFraction)

⇒ 3 (x/4) - 1/2 (x/10)

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

The expression is,

⇒ 70% of x

Now, We an simplify the expression as;

⇒ 70% of x

⇒ 70/100 × x

⇒ 70x/100

⇒ 7x/10

By option 1;

⇒ 3 (x/4) - 1/2 (x/10)

⇒ 3x/4 - x/20

⇒ (60x - 4x) / 80

⇒ 56x / 80

⇒ 7x/10

Answer: 36

12 out of 15 people play in the school band. In the class, 36 do not play.

12:15 is equal to a ration of 36:45.

So, it is the answer. 36 out of 45 people in the class play in the band.

Hope this helps!

Answer:

9 I think

Step-by-step explanation:

I wanted to simplify 12 out of 15 and I did by dividing 3 out of both of them which would now equal 4 out of 5. I know that 4 out of 5 is 80%. so, I did 80 % of 45 which equals 36 which means 36 people were in band. So now you minus 36 from 45 which is 9

9 people did not play in band

Step-by-step explanation:

Answer:

removable

Step-by-step explanation:

f(x) = cos(1/x^2) at x = 0;

For the function f(x) = cos(1/x^2) let's substitute the value of 0 in for x...

= cos(1/(0)^2)

= cos(1/0)

Now remember that x/0 is undefined. Removable discontinuity is undefined at the point x₀, and hence our solution is "removable."

c would then equal 33, which is greater than 30

Answer:

False

Step-by-step explanation:

False

I'm assuming its because x isn't negative infinity because the leading coefficient is positive

The graph is shown below, therefore the given statement is false.

The given polynomial f(x)=2x³-9x²+11x-20 as x→-∞, f(x)→∞.

To solve a polynomial equation first, write it in standard form. Once it is equal to zero, factor it and then set each variable factor equal to zero.

Now, (0, -20), (1, -16), (2, -18), (3, -14) and (4, 8).

The graph is shown below, therefore the given statement is false.

Hey there!

The given midpoint is; X(-8,4) and G(2,-9).

To find: H

Now; You need to use formula for midpoint.

[tex]midpoint(x) = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )[/tex]

Put all values.

[tex]( - 8,4) = (\frac{ 2 + x}{2} , \frac{ - 9 + y}{2} )[/tex]

As they are equal, their corresponding elements are equal.

[tex] - 8 = \frac{2 + x}{2} [/tex]

[tex] - 16 - 2 = x[/tex]

x = -18

[tex]4 = \frac{ - 9 + y}{2} [/tex]

[tex]4 \times 2 = - 9 + y[/tex]

[tex]8 + 9 = y[/tex]

[tex]y = 17[/tex]

Therefore, y = 17.

Therefore, H =( -18,17).

A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

The sum of two sides of a triangle is greater then the third side. Mathematically -

a + b > c

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is a triangle PQR and line segment AB, which is parallel to QR.

[A] -

ΔPQR is similar to ΔPAB as -

∠P = ∠P (Common)

∠PAB = ∠PQR (Corresponding angles)

∠PBA = ∠PRQ (Corresponding angles)

Step-by-step explanation:

Answer:

I think it is (-1/9)(3/5)>-2/15

Problem 2, Part (a)

A = event elevator's 1st stop at the 2nd floor

P(A) = 3/4

Since the elevator needs to go up one floor

B = event elevator has its 2nd stop at the 3rd floor

P(B given A) = probability event B happens given event A happened

P(B given A) = 3/4

-----------

P(A and B) = P(A)*P(B given A)

P(A and B) = (3/4)*(3/4)

P(A and B) = 9/16

-----------

===============================================================

Problem 2, Part (b)

A = event elevator's 1st stop at the 2nd floor

P(A) = 3/4

B = event elevator has its 2nd stop at the 3rd floor

P(B given A) = 3/4

C = event elevator has its 3rd stop at 4th floor

P(C given (A and B)) = 3/4

-----------

P(A & B & C) = P(A)*P(B given A)*P(C given (A and B))

P(A & B & C) = (3/4)*(3/4)*(3/4)

P(A & B & C) = 27/64

-----------

===============================================================

Problem 2, Part (c)

A = event elevator's 1st stop at the 2nd floor

x = P(A) = 3/4

B = event elevator has its 2nd stop at the 3rd floor

y = P(B given A) = 3/4

C = event elevator has its 3rd stop at 2nd floor

z = P(C given (A and B)) = 1/4

D = event elevator has its 4th stop at 1st floor

w = P(D given (A & B & C)) = 1/4

-----------

P(A & B & C & D) = x*y*z*w

P(A & B & C & D) = (3/4)*(3/4)*(1/4)*(1/4)

P(A & B & C & D) = 9/256
