All circles = 360*

we can subtract 260 from that because we know the length of one so we know the other is 130.

We are then left with only 100 and we know the two sides are equivalent so 100 / 2 = 50

13a=-5
12−b=12.5
-0.1=-10c

Answers

1) 13a=-5
Make a the subject of the formula by dividing both sides by 13(the coefficient of a)
13a/13=-5/13
Therefore a= -0.385

The second one). 12-b= 12.5
You take the 12 to the other side making b subject of the formula (-b in this case)
-b= 12.5-12
-b= 0.5
(You cannot leave b with a negative sign so you will divide both sides by -1 to cancel out the negative sign)

-b/-1= 0.5/-1
Therefore b=-0.5

The third one). -0.1= -10c
You will divide both sides by the coefficient of c(number next to c) which is -10
-0.1/-10= -10c/-10

Hence, c= 0.01

the distance, in feet, the object has dropped. Find the distance when the velocity is
32 ft/sec.

Answers

Answer:

d = 0.0625 m

Step-by-step explanation:

The velocity of an object dropped from a tall building is given by :

[tex]v=\sqrt{64d}[/tex]

Where

d is the distance in feet

We need to find the distance when the velocity is 32 ft/s

Rearranging for d,

[tex]v^2=64d\\\\d=\dfrac{64}{v^2}[/tex]

Put v = 32 ft/s

[tex]d=\dfrac{64}{32^2}\\\\d=0.0625\ m[/tex]

So, the required distance is 0.0625 m.

When q = 1/2,

The 2 from the denominator of (1/2) will go up to the numerator of (18) / (1/2). We will be left with,

If P = 3x2 + xy - 5y? Q = 2x2 - xy + 3y2 and R = -6x2 + 4xy - 7y2?
what is P+Q-R?

Answers

Answer:

is this helpful tell me please if im correct :)

Answer:

[tex]P+Q-R=11x^2-4xy+10y^2[/tex]

Step-by-step explanation:

I'm assuming the 2's at the end of some of the terms are meant to be exponents. So here we have

[tex]P=3x^2+xy-5y\\Q=2x^2-xy+3y^2\\R=-6x^2+4xy-7y^2[/tex]

and we're asked to find P + Q - R. Let's handle these operations left to right to cut down on clutter. Starting with P + Q, our first job should be to combine all the like terms we can. 3x² + 2x² = 5x², and xy - xy = 0, but we still can't do anything with the terms -5y and 3y². So far, this gives us

[tex]P+Q=5x^2-5y+3y^2[/tex]

Now let's handle subtracting R from this sum. The pairs of like terms here are 5x² and -6x², and 3y² and -7y². Subtracting these parts gives us 5x² - (-6x²) = 11x² and 3y² - (-7y²) = 10y², and we can subtract off the remaing 4xy in R to give us

[tex]P+Q-R=11x^2-4xy+10y^2[/tex]

How many moles of water are produced when 3.0 moles of hydrogen gas reacts with 1.8 moles of oxygen gas?
Balanced equation: 2H2 + O2 + 2H20
O 3.0 moles of water
O 3.6 moles of water
O 5.3 moles of water
O 7.0 moles of water

Answers

Answer:

3 moles of water are produced

Step-by-step explanation:

Find the limiting reactant

3.0 moles of H2 x (2 moles of H2O/2moles of H2)=3.0 moles of H20--limiting reactant, so this is the maximum amount of product that can be produced! Hope this helps

1.8 moles of O2 x (2 moles of H20/1 moles of O2)=3.6 moles of H20

3.6 moles of water are produced when 3.0 moles of hydrogen gas reacts with 1.8 moles of oxygen gas.

What is mole ?

In chemistry, a mole is a unit of measurement used to quantify the amount of a chemical. It is defined as the amount of a substance containing Avogadro's number of entities (about 6.022 x [tex]10^{23[/tex]particles). The mole is a unit of measurement that is used to express the amount of a substance in terms of its molecular or atomic count. The mole is especially important in chemical reactions, where it is used to balance the number of atoms or molecules present in the reactants and products.

We have the balanced Equation:

2[tex]H_2[/tex] +  [tex]O_2[/tex] ----> 2[tex]H_2O[/tex]

As, 3.0 moles of Hydrogen gas reacts with 1.8 moles of oxygen gas.

So, 1.8 moles of [tex]O_2[/tex] x (2 moles of [tex]H_2O[/tex] /1 moles of [tex]O_2[/tex])

= 3.6 moles of [tex]H_2O[/tex]

Also, 3.0 moles of Water is the limiting reactant.

Answers

Answer: The walking path around it.

Step-by-step explanation:

Remember the Pythagorean's theorem, for a triangle rectangle with catheti A and B, and with hypotenuse H, we have:

A^2 + B^2 = H^2

or

H = √(A^2 + B^2)

Here, A + B is the total distance for the path, while the hypotenuse is the distance for the bridge

Here we can see that:

A = 1170 ft

B = 520 ft

Then:

H = √( (520 ft)^2 + (1170 ft)^2) = 1280.4 ft

Now, let's compute the costs.

For the bridge, we know that each foot costs $11, then for 1280.4 ft the cost is:

Cost of the bridge = (1280.4)*$11 = $14,084.4

And for the walking path, the cost is $6 per foot, then the total cost of the path is:

Cost of the path = (520 ft + 1170 ft)*$6 = $10,140

We know that the bridge is preferred if it is within the range of $1500 for the path's cost.

This range is:

($10,140 - $1,500, $10,140 + $1,500) = ($8,640, $11,640)

Here we can see that the cost of the bridge does not belong to this range, (is higher) so the option we should recommend is the walking path around.

Please help I need to pass my class

Answers

Answer:

Step-by-step explanation:

sin(D) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

         = [tex]\frac{7}{14}[/tex]

         = [tex]\frac{1}{2}[/tex]

         = 0.5

cos(D) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

          = [tex]\frac{12.124}{14}[/tex]

          = 0.866

tanD = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

        = [tex]\frac{7}{12.124}[/tex]

        = 0.577

Since, sinE = cosD

Therefore, sinE = 0.866

Since, cosE = sinD

Therefore, cosE = 0.5

Since, tanE = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

                   = [tex]\frac{12.124}{7}[/tex]

                   = 1.732

A circle is centered at (0,0) and has a radius of 2\sqrt{3}

Where does the point M(−3,2) lie?

Answers

Answer:

Outside of the circle

Step-by-step explanation:

First, find the equation of the circle by plugging in the center point and radius:

(x - h)² + (y - k)² = r²

(x - 0)² + (y - 0)² = ([tex]2\sqrt{3}[/tex])²

x² + y² = 12

Plug in point M to see where it lies:

x² + y² = 12

(-3)² + (2)² = 12

9 + 4 = 12

13 ≠ 12

Since this statement is false, point M lies outside of the circle.

where y and x are variables, m is the slope of the graph and b is the y intercept.

A system of linear equations has infinitely many solutions, when the lines overlap at every point. In other words, they're the same exact line, having the same equation when simplified.

Which of these strategies would eliminate a variable in
the system of equations?
8x + 8y = 2
8x + 5y = 1

Answers

Answer:x = -1 / 12

Step-by-step explanation: am i right??

8x + 8y = 2 -------(1)

8x + 5y = 1 -------(2)

subtract equation (2) from equation (1)

The 8x will be eliminated, leaving us with;

3y = 1

Divide bothside of the equation by 3

y = 1/3

substituting y = 1/3 in equation (1)

8x + 8y = 2

8x + 8(1/3) = 2

8x + 8/3 = 2

subtract 8/3 from both-side

8x + 8/3 -8/3 = 2 -8/3

8x = 2 - 8/3

8x = 6 - 8 / 3

8x = - 2/3

Divide both-side of the equation by 8

8x / 8 = -2/3 ÷ 8

x = -2/3 × 1/8

x = -1 / 12
