If y varies directly as x, and y is 180 when x is n and y is n when x is 5, what is the value of n?

Mathematics

Answer:

n = 30

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 180 when x = n, then

180 = kn ( divide both sides by n )

k = \frac{180}{n}

y = \frac{180}{n} x ← equation of variation

y = n when x = 5, thus

n = \frac{180}{n} × 5 = \frac{900}{n} ( multiply both sides by n )

n² = 900 ( take the square root of both sides )

n = \sqrt{900} = 30

I need help to find m
Neko [114]

Answer:

∠MNO = 75°

Step-by-step explanation:

∠mno = 1/2 ( arc MLP - arc MOP )

arc MLP = 241 and arc MOP = 91

so ∠MNO = 1/2 ( 241 - 91 )

241 - 91 = 150

150/2 = 75

Hence, ∠MNO = 75°

Taylor is making a mini apple pie with a radius of 3.14 in for her math class. what is the area of her mini pie?
artcher [175]

So First of all we need to know how to find the area of a circle.

Assuming that the apple pie is the shape of a circle

The formula for area is \pi r^{2}

Well we know that the radius = 3.14

And we know that \pi = 3.14 as well.

All we have to do is multiply..

3.14 x 3.14^{2} = 30.95

So the area of the pie is 30.95 in


Good Luck! :)

23 and 25 <br> how do you do the work?<br> find the areas of each
stiks02 [169]

Answer:

  23)  35.77 in²

  25)  48.19 cm²

Step-by-step explanation:

Use the appropriate area formula with the given information.

__

23) The area of a triangle is given by the formula ...

  A = 1/2bh . . . . . base b, height h

  A = 1/2(9.8 in)(7.3 in) = 35.77 in²

__

25) The area of a parallelogram is given by the formula ...

  A = bh . . . . . . base b, height h

  A = (7.9 cm)(6.1 cm) = 48.19 cm²

_____

The <em>height</em> in each figure is <em>measured perpendicular to the base</em>. This tells you that the length 10.6 cm of the diagonal side of the triangle is not relevant to finding the area.
