Step-by-step explanation:

The maximum number of pounds p is 224

Step-by-step explanation:

Let

p ----> the maximum number of pounds he can pull without going over the weight limit

we know that

121 pound of rock in the wheelbarrow plus p pounds must be at most 345 pounds

In this problem the word "at most" means "less than or equal to"

so

The inequality that represent this situation is

solve for p

subtract 121 both sides

therefore

The maximum number of pounds is 224

Answer:

67°

Step-by-step explanation:

9x+2=74

9x=72

x=8

m<2 = 180-(5(8)-1+74)

= 180-(39+74)

=180+113

= 67°

Answer:

the timing taken to solve each math problem and each biology problem is 4 minutes each respectively

Step-by-step explanation:

Let us assume the timing taken for math problem be x

And, the time taken for biology problem be y

Now as per the question

The following equations should be considered

x + 2y = 14 .............(1)

2x + y = 16. ...................(2)

Multiply by 2 in equation 1

So,

2x + 4y = 28

2x + y = 16

3y = 12

y = 4 minutes

So, x = 14 - 2(4)

= 12 - 8

= 4 minutes

hence, the timing taken to solve each math problem and each biology problem is 4 minutes each respectively

Answer:

y=36x, I think would be the correct answer

Answer:

268.3 cm³

Step-by-step explanation:

Surface area of triangular pyramid = Base Area + ½*(perimeter of base)(height of pyramid)

Base area = 43.3 cm²

Perimeter of base = 10 + 10 + 10 = 30 cm

Height of pyramid = 15 cm

Plug in the values

Surface area = 43.3 + ½(30)(15)

Surface area = 43.3 + 225

Answer:

y = -2/3x + 1

Step-by-step explanation:

y = -2/3x + b

-1 = -2/3(3) + b

-1 = -2 + b

1 = b

y = -2/3x + 1

The height of the cone can be written as h = 3V/(π × r²).

A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.

The formula for the volume of cone is given as V = 1/3 × π × r² × h.

It can be written in terms of h by the method of solving a linear equation as follows,

V = 1/3 × π × r² × h

=> 3V = π × r² × h

=>  h = 3V/(π × r²)

Hence, the expression for height from the given formula can be written as h = 3V/(π × r²).

See Below.

Step-by-step explanation:

We have:

[tex]\displaystyle \cos\theta\cdot \cot\theta+\sin^2\theta\cdot \csc\theta=\csc\theta[/tex]

Rewrite:

[tex]\displaystyle \cos\theta\left(\frac{\cos\theta}{\sin\theta}\right)+\sin^2\theta\left(\frac{1}{\sin\theta}}\right)=\csc\theta[/tex]

Multiply:

[tex]\displaystyle \frac{\cos^2\theta}{\sin\theta}+\frac{\sin^2\theta}{\sin\theta}=\csc\theta[/tex]

Combine:

[tex]\displaystyle \frac{\cos^2\theta+\sin^2\theta}{\sin\theta}=\csc\theta[/tex]

According to the Pythagorean Identity, sin²θ + cos²θ = 1. Hence:

[tex]\displaystyle \frac{1}{\sin\theta}=\csc\theta[/tex]

Simplify:

[tex]\csc\theta=\csc\theta[/tex]

12)

We have:

[tex]\displaystyle \frac{\cos^2\theta +\sin^2\theta}{1+\tan^2\theta}=\cos^2\theta[/tex]

Pythagorean Identity:

[tex]\displaystyle \frac{1}{1+\tan^2\theta}=\cos^2\theta[/tex]

From the Pythagorean Identity, if we divide both sides by cos²θ, we acquire that tan²θ + 1 = sec²θ. Hence:

[tex]\displaystyle \frac{1}{\sec^2\theta}=\cos^2\theta[/tex]

Simplify:

[tex]\cos^2\theta =\cos^2\theta[/tex]

13)

We have:

[tex]\displaystyle \frac{\csc\theta\cdot \cos\theta}{\tan\theta +\cot\theta}=\cos^2\theta[/tex]

Rewrite:

[tex]\displaystyle \frac{1/\sin\theta\cdot \cos\theta}{\sin\theta/\cos\theta+\cos\theta/\sin\theta}=\cos^2\theta[/tex]

Multiply both top and bottom by cosθsinθ. Hence:

[tex]\displaystyle \frac{\cos^2\theta}{\sin^2\theta +\cos^2\theta}=\cos^2\theta[/tex]

By the Pythagorean Identity:

[tex]\displaystyle \frac{\cos^2\theta}{1}=\cos^2\theta[/tex]

Simplify:

Answer:

2 or 2/1

Step-by-step explanation:

First we put -"3y" to the other side of the equation to get

3y=6x+6

Now divide everything by 3 to get "y" by itself.

y=2x+2

The slope is 2 or 2/1

Answer:

b.2

Step-by-step explanation:

6x-3y+6=0

-3y=-6x-6 divide both sides by -3

y=2x+2

Graph D

Step-by-step explanation:

The slope of the data is 2.5 because 2.5 cups of flour are used for every ounce of butter. Some points on the graph we can use is (0,0) and (10,4).

(0,0): When there are 0 cups of flour, there are 0 ounces of butter.

(10,4): When there are 10 cups of flour, there are 4 ounces of butter.

Slope=m

[tex]m=\frac{Change(y)}{Change(x)}[/tex]

[tex]m=\frac{10-0}{4-0}[/tex]

[tex]m=\frac{10}{4}[/tex]

[tex]m=2.5[/tex]

Graph D is the only graph containing the point (10,4) and (0,0). So, Graoh D is the correct graph.
