Answer:

51.3 packets or 51 1/3 packers

Step-by-step explanation:

From the above question:

The board he needs comes in packs of three. This means

1 pack = 3 boards

Hence:

3 boards = 1 packet

154 boards = x

Cross Multiply

3x = 154

x = 154/3

x = 51.333333333 packets

Approximately = 51.3 packets or 51 1/3 packers

The builder will need to buy 51.3 packets or 51 1/3 packers

Answer:

Given the reference to the chain rule, I assuming by "calculate", you mean "take the derivative of", in which case we have:

For the first function:

[tex]y = (2u^2 + 3)^{\frac{1}{3}}\\\\\frac{dy}{du} = \frac{1}{3}(2u^2 + 3)^\frac{-2}{3}(4u)\\\\\frac{dy}{du} = \frac{4u}{3}(2u^2 + 3)^\frac{-2}{3}\\\\\frac{dy}{du} = \frac{4u}{3(2u^2 + 3)^\frac{2}{3}}[/tex]

and for the second one:

[tex]u = \sqrt{2x + 1}\\\\u = (2x + 1)^{0.5}\\\\\frac{du}{dx} = 0.5(2x + 1)^{-0.5}(2)\\\\\frac{du}{dx} = \frac{1}{\sqrt{2x + 1}}[/tex]

Answer:

y=−x+2y=4x+7   NO

y=−x+2               YES

y=4x+7            

Multiply the first equation by 4, obtaining:              4y = -4x + 8

Add the 2nd equation to this result:                          y = 4x  + 7

                                                                            --------------------

                                                                                5y = 15, and y = 3

Then, using the first equation, determine x:

y = 3 = -x + 2

      1 = -x, so x = -1

The solution is (-1, 3)

Answer: (-1; 3)

Step-by-step explanation:

y = -x + 2

y = 4x + 7

4x + 7 = -x + 2

4x + 7 + x - 7 = - x + 2 + x - 7

5x = - 5

x = - 1

y = 4(-1) + 7

y = 3

Intersection point: (-1; 3)

Answer:

B: y=sinx

Step-by-step explanation:

the parent sine function is a repeating function that goes from 0 to 1, with sin(0)=0 sin(pi/2)=1 sin(pi)=0 sin(3pi/2)=-1 and sin(2pi)=0, π≈3.1415926 and we see on this graph that the graph matches at all these major points.

the cosine parent function is essentially the same thing but shifted to the left by π/2. It is essential to familiarize yourself with the unit circle and the key angles and their respective sin and cosine values.

The answer is y = sin x!!

Answer:

x = -5 and y = 2

Step-by-step explanation:

You want to start by writing these two equations:

x + y = -3

and

x - y = -7

Then, you want to add the solutions to these two equations, like so:

-3 + -7 = -10

Then, to find the x value, because x > y, divide the answer by two:

-10/2 = -5

So, the x value is -5.

With this information, you can figure out that the y value is 2.

Check the answer:

-5 + 2 = -3

-5 - 2 = -7

Answer:

Step-by-step explanation:

Vertex form of quadratic equation with coordinate of vertex (h, k) is

y = a(x - h)² + k

Answer:

∠y° = ∠69°

∠x = ∠69°

Step-by-step explanation:

1) The question relates to parallel line theorem

The given parameters are;

AB is parallel to CD

∠111° and ∠y° are consecutive interior angles

∠69° and ∠x° are alternate interior angles

When two parallel lines are crossed by a common transversal, the consecutive interior angles are supplementary (sum up to 180°), and the alternate interior angles are equal

Therefore, we have;

∠111° + ∠y° = 180°

∠y° = 180° - ∠111° = ∠69°

∠y° = ∠69°

2) For the alternate interior angles, ∠69° and ∠x°, we have;

Alternate angles are equal, therefore ∠x = ∠69°

Answer:

1. 12  2. 12  3.1/8    4. 11  5. -15   6.-60   7.20  8.225

Step-by-step explanation:

Given that :

m=2 and n=16 , p = {1-6 =-5}  then;

1.  m+10 = 2+10 = 12

2. n-4 = 16-4 = 12

3. m / n = 2/16 = 1/8

4. 6m - 1 = 6*2 - 1 = 12 -1 = 11

5. 3p =3* -5 = -15

6.12 p = 12* -5 = -60

7. 12m-4 = 12*2 - 4 = 24 -4 =20

8. 9p² = 9*-5² = 9 * 25 = 225

5x^5/6

Step-by-step explanation:

Step-by-step explanation:

Find the radius: 6 ÷ 2 = 3m

Circumference = 2r with pi = 3cm x 3.14cm x 2 = 18.84m

Area = pi x 3cm x 3cm = 28.27m2

Calculate the circumference and area of given triangle.

Circumference of circle = 2πr

Area of circle = πr²

Radius,r = diameter/2 => 6/2 = 3 m

( i ) As we know that formula of circumference,

Circumference of circle = 2πr

[tex] \bf \: \star \: putting \: the \: values[/tex]

5x + 4y = 20 on a graph

Step-by-step explanation:

Step-by-step explanation:

Using FOIL, we have

(x + 2)(x² - 3x + 4)

= (x³ - 3x² + 4x) + (2x² - 6x + 8)

= x³ - x² - 2x + 8.

Answer:

41.25 ft^2

Step-by-step explanation:

Literally all you need to do is Pythagorean Theroem.

a = ?

b = 11ft

c = 8ft

a^2 + b^2 = c^2

a^2 + 11^2 = 8^2

a^2 + 121 = 64

64 - 121 = a^2

a = 7.5

Then area of a triangle formula is (bh)/2

(11 x 7.5)/2 = 41.25

Answer:

7

Step-by-step explanation:

6,300 divide by 900 would equal 7

Answer:

7 beams

Step-by-step explanation:

To find how many beams can be made from steel, we have to find how many times 900 goes into 6,300. So our equation is:

6,300 ÷ 900 = 7

So you can make 7 beams out of 6,300 pounds of steel (and you won't have any steel left.)

Answer:

slope= -3,y - intercept y = -2

Step-by-step explanation:

- Make y the subject by taking four on the opposite side of the equal sign.

2y = -6x - 4

- Divide throughout by 2 and from there you get the gradient which is also the slope.

- To get the y - intercept,the value of x =0. Thus you get y =-2.
