Answers

Answer 1

Answer:

3 943.84π

Step-by-step explanation:

tienes que usar la fórmula de: pi por radio al cuadrado

Answer 2

Answer:

[tex]314in^{2}[/tex]

Step-by-step explanation:

Circumference is [tex]2\pi r[/tex]

Find your radius

[tex]2\pi r=62.8\\\pi r=31.4\\[/tex]

Let [tex]\pi =3.14[/tex] for simplicity

r=[tex]\frac{31.4}{3.14}[/tex]=10

Now use the equation for the area of a circle to find the area of the clock face.

Area of a circle is [tex]\pi r^{2}[/tex]

Area of clock face is [tex]\pi (10^{2} )[/tex]

=[tex]100\pi[/tex]

The base of a 14-foot ladder is 5 feet from a building, If the ladder reaches the flat roof, how tall is the building?

Answers

Using trigonometry you use cosine and get a final answer of 13.067 ft tall

The height of the wall of the building is 13.067 feet.

What is the Pythagorean theorem?

Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Given that the base of a 14-foot ladder is 5 feet from a building. The height of the building will be calculated as below:-

Applying the Pythagorean theorem to calculate the height of the building.

H² = P² + B²

14² = P² + 5²

P² = 14² - 5²

P = √171 = 13.07 feet

Therefore, the height of the wall of the building is 13.067 feet.

(Show solving steps please)

Answers

Answer:

x=r/2+y/2

Step-by-step explanation:

2x-y=r

you want x all by itself, move y first by adding y

2x = r + y

divide both r and y by 2 to leave x all by itself.

2x/2 = r/2 + y/2

2/2 = 1 so it's really 1x

Step-by-step explanation:

2(x+7)=72 no, because this only changes the value on the right side. so this equation is not about the same equality anymore.

x+7=18 yes, because both sides were transformed by the same operation (division by 2). the equality is still maintained.

2x+7=36 no, because 2x+7 is NOT equal to 2(x+7). resolving 2(x+7) is 2x+14.

x+14=36 no, because again, x+14 is NOT equal to 2(x+7).

(2×x) + (2×7) = 36 yes, because the left side is a valid transformation of 2(x+7).

2x+14=36 yes, because the left side is a valid transformation of 2(x+7).

Given the system of equations, what is the solution?

2x + y = 7
2x - 3y = -1

Answers

Answer:

[tex](\frac{5}{2}, 2)[/tex]

Step-by-step explanation:

Hi there!

We are given this system of equations:

2x + y = 7

2x - 3y = -1

And we want to find the solution

There are multiply ways to solve systems of equations, but let's solve this one by elimination, where we will add the two equations together to clear one of them, solve for the un-cleared variable, and then use the value of the un-cleared variable to solve for the cleared one

Before clearing a variable, we need to make sure that the signs on the variables are opposites; for example, -3 and 3, which will add together to get 0

We can multiply the equations beforehand if needed in order to manipulate the numbers.

For example, we can multiply the second equation by -1 in order to switch the signs of each number in that equation:

-1(2x-3y=-1)

-2x+3y=1

Now the signs in front of x are 2 and -2, so we can add the equations together to clear them:

2x + y = 7

-2x + 3y = 1

Add the equations together

4y = 8

Divide both sides by 4

y=2

Now let's use 2 as y to solve for x

In the first equation, substitute 2 for y:

2x + 2 = 7

Subtract 2 from both sides

2x = 5

Divide both sides by 2

[tex]x=\frac{5}{2}[/tex]

As a point, the answer is [tex](\frac{5}{2}, 2)[/tex]

Manuel wants 30 liters of a mixture of water and 10% lemon juice. He has a mixture of 8% lemon juice and a mixture of 20% lemon juice. How many liters of the 8% and 20% mixtures should he mix to get what he wants?

Answers

Manuel needs 20 liters of the 8% and 5 liters of 20% mixtures to be mixed so as to get 30 liters of a mixture of water and 10% lemon juice.

Let x represent the amount of 8% lemon juice in liters and y represent the amount of 20% lemon juice in liters.

Since Manuel wants to produce a 30 liters mixture from 8% lemon juice and 20% lemon juice, hence:

x + y = 30      (1)

Also, Manuel wants 30 liters of a mixture of water and 10% lemon juice, hence:

8% of x + 20% of y = 10% of 30 liters

0.08x + 0.2y = 3         (2)

Solving equation 1 and 2 simultaneously; multiply equation 1 by 0.2 and subtract equation 2 from the result:

0.12x = 3

x = 25 liters

x + y = 30

25 + y = 30

y = 5 liters

Manuel needs 20 liters of the 8% and 5 liters of 20% mixture

to get the x by itself, you need to subtract 5 from both sides

5-5 +x = -2-5

there for 0 + x = -7 which means x=-7

2. to get 8m to just m, you need to divide 8m by 8. and what you do to one side of the equation, you need to do to the other. therefore 8m/8=48/8 and 48/8=6. therefore m=6

1. 5+x=-2

x=-2-5

x= -7

2. 8m=48

m= 48/8

The question is an illustration of the sine function.

The average daily fuel consumption is 30.3The vertical shift represents the average daily fuel consumption

The function is given as:

[tex]\mathbf{C = 30.3 + 21.6\sin(\frac{2\pi t}{365} + 10.0)}[/tex]

A sine function is represented as:

[tex]\mathbf{y = a\sin(bx - c) + d}[/tex]

Where d represents the vertical shift.

In this case, d represents the average rate

So, the average daily fuel consumption is 30.3
