1/7 divided by 4 equals

1 answer:

6 0

1/ 28 is the answer.
= 1/7 ÷4
= 1/7 ÷ 4/1
=1/7 X 1/4
Multiply top by top, bottom by bottom
=1/28

If you do not know how to do it:
First make both sides into a fraction ( Whole numbers always have a 1 as a denominator).
Then you reciprocate (Flip) the second fraction.
Finally you multiply top by top, bottom by bottom
You get the answer!<span />

MAVERICK [17]

Answer:

$P(x) = 3x - 10$

Step-by-step explanation:

Given

$R(x) = 5x$

$C(x) = 10 + 2x$

Required

Determine $P(x) = (R - C)(x)$

In functions;

$(f - g)(x) = f(x) - g(x)$

So, we have:

$P(x) = (R - C)(x)$

$P(x) = R(x) - C(x)$

Substitute values for R(x) and C(x)

$P(x) = 5x - (10 + 2x)$

Open bracket

$P(x) = 5x - 10 - 2x$

Collect Like Terms

$P(x) = 5x - 2x- 10$

$P(x) = 3x - 10$

Answer:

z = 55.15432893

x = 59.61543424

y = 22.5166605

Step-by-step explanation:

To find length "z" you will have to use SOHCAHTOA.

Labelling the triangle will show us that the side marked "z" is the hyp and the side marked 39 is the opp.

sin 45 = $\frac{39}{z}$

z sin 45 = 39

z = $\frac{39}{sin45}$

z = 55.15432893

Using Pythagoras' theorem, you can find that the adj = 39

In the other triangles POV, the adj is actually the opp.

Therefore, use tangent to find y.

tan 60 = $\frac{39}{adj}$

y tan 60 = 39

y = $\frac{39}{tan60}$

y = 22.5166605

Use Pythagoras's Theorem to find x.

$23^{2} + 55^{2} = x^{2}\\\sqrt{23^{2} + 55^{2}} = x\\59.61543424=x$

What is the perimeter of abc with vertices a(-2 9)?

vazorg [7]

For finding the perimeter of abc (triangle), we MUST need the two others coordinates of b and c
let b(1, 2) and c (2, -4)
we need to calculate the distances ab, ac, and bc
vector (ab)=(1-(-2), 2-9)=(3, -7), so its length is ab=sqrt(3²+ (-7)²)=7.61
realising the same method, we find bc=6.08, ac=13.60

so the perimeter of abc is P= ab+bc+ca=13.60+6.08+7.61=27.29
