what is the answer 3⁻⁶ x (3⁴ ÷ 3⁰)² =

Answer: 140 female runners

Step-by-step explanation:

First find out the number of runners:

= 42% * 10,000

= 4,200 runners

Then find out the number of female runners:

= 4,200 * 1/3

= 1,400 female runners

Sally finished faster than 90% of the female runners which means that 10% finished faster or at the same time as her.

= 10% * 1,400

= 140 female runners

Answer:

B.

Step-by-step explanation:

To answer, lets look at the definitions of each name.

First, a quadrilateral. A quadrilateral is a polygon in Euclidean plane geometry with four edges and four vertices, so it basically just has 4 sides, which this figure has, so this figure is a quadrilateral.

Next, a parallelogram. A parallelogram is a four-sided plane rectilinear figure with opposite sides parallel. So as long as a figure has 4 sides and at least 2 opposite sides that will never collide, it is a parallelogram. Because our figure has 4 sides and each pair of opposite sides is parallel, this figure is a parallelogram.

Last, a rectangle. A rectangle is a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square. So, as long as there are 4 sides and 4 right angles, and 2 of the opposite sides are longer than the other set of opposite sides, it is a rectangle, and this figure fills all the requirements.

So, since the figure is a quadrilateral, a parallelogram, and a rectangle, the answer is B.

Hope this helps :)

Answer:

m∠PNO = 60°

m∠O = 33°

Step-by-step explanation:

∡NPO is 87° because it's a vertical angle with the 87° angle

3) ∡PNO is supplementary to the 120° angle (they must add to 180°)

4) m∠O = 180 - (60 + 87) = 33

Answer:

Assuming they are equal to each other, X = -4

Step-by-step explanation:

6x + 25 = x + 5

Subtract 5 from both sides

6x + 20 = x

subtract 6x from the left side

20= 5x

divide by 5

-4 = x

Step-by-step explanation:

ok lets imagine if the variables were x and y

the equation would be as follows

y=3x+2

y=-1/3x+7

The answer will be an ordered pair, (x,y) because that specifies exactly where on graph, instead of a general location which you would get if you only had the x or only had the y

Step-by-step explanation:

Answer:

the distance is about 106.36 feet

The distance between the courthouse and the bank is about 81.8 feet.

The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.

|AC|^2 = |AB|^2 + |BC|^2  

We are given that;

Height of court house= 90 foot

Height of bank= 54 foot

Now,

Use the tangent function to write two equations relating x, y, and the angles. For example:

tan(72°)=x90​

tan(35°)=y54​

Solve for x and y by multiplying both sides by x and y respectively. For example:

xtan(72°)=90

ytan(35°)=54

Divide both sides by tan(72°) and tan(35°) respectively to get x and y. For example:

x=tan(72°)90​≈24.8

y=tan(35°)54​≈77.9

Use the Pythagorean theorem to find z in terms of x and y. For example:

z2=x2+y2

Substitute the values of x and y and simplify to get z. For example:

z2=(24.8)2+(77.9)2

z2=615.04+6068.41

z2=6683.45

z=6683.45​≈81.8

Therefore, by Pythagoras theorem the answer will be 81.8 feet.

Answer:

80p2 - 180r2

20(4p²-9r²)

20(2p+3r)(2p-3r)

Answer:

20(2p - 3r)(2p + 3r)

Step-by-step explanation:

Given

80p² - 180r² ← factor out 20 from each term

= 20(4p² - 9r²) ← difference of squares which factors in general as

a² - b² = (a - b)(a + b)

4p² - 9r²

= (2p)² - (3r)² ← with a = 2p and b = 3r

= (2p - 3r)(2p + 3r)

Thus

80p² - 180r² = 20(2p - 3r)(2p + 3r) ← in factored form

Answer:

x = 5/2   y = 3/2

Step-by-step explanation:

You need to write what the question is besides the information in the problem.  I assume the question is to find the values of x and y.

Going on that premise, Let equation (1)   be -5x + 3y = -8 and

equation (2)  be 3x - 7y = -3

Lets multiply (1) by 3 and (2) by 5 and we get equations (4) and (5)

(4)   -15x + 9y = -24    and  (5)    15x - 35y = -15  Now add (4) and (5)

-15x + 9y = -24

15x - 35y = -15

      -26y = - 39

y = 3/2     Now substitute y = 3/2 in equation (1).  -5x + 3)(3/2) = -8

                                                                                 -5x + 9/2 = -8

                                                                                  -10x + 9 = -16

                                                                                  -10x = -25

                                                                                      x = -25/-10 = 5/2  

x = 5/2   y = 3/2

Check:  Substitute your answers into equation (2) and see if they work.

3(5/2) -7(3/2) = 15/2 - 21/2 = -6/2 = -3   Hooray!  We have the correct values for x and y that makes each equation true

Answer:

no solutions

Step-by-step explanation:

Given the 2 equations

y = - 7x + 8 → (1)

y = - 7x - 8 → (2)

Substitute y = - 7x - 8 into (1)

- 7x - 8 = - 7x + 8 ( add 8 to both sides )

- 7x = - 7x + 16 (add 7x to both sides )

0 = 16 ← not possible

This indicates the system has no solutions

Hey there!

The answer to your question is [tex]no[/tex] [tex]solutions[/tex]

To solve this, we will set the equations equal to eachother. We know that since the two expressions, [tex]-7x+8[/tex] and [tex]-7x-8[/tex] both equal [tex]y[/tex], then the expressions are equal. (Somebody comment what property that is, I forgot what it's called) So:

[tex]-7x+8=-7x-8\\[/tex]

Add [tex]8[/tex] to both sides:

[tex]-7x+16=-7x[/tex]

Add [tex]7x[/tex] to both sides:

[tex]16 = 0[/tex]

Therefore, there are [tex]no[/tex] [tex]solutions[/tex].
