Express the ratio 7 days to 6 weeks as a decimal fraction​
Mashcka [7]

Answer:

0.166

Step-by-step explanation:

We know that,

1 week = 7 days

i.e.

6 week = 7(6) days = 42 days

We need to express ratio 7 days to 6 weeks as a decimal fraction​. So,

R=\dfrac{7\ \text{days}}{42\ \text{days}}=\dfrac{1}{6}\\\\=0.166

How do i solve this?
tigry1 [53]

Answer:

  x = 5

Step-by-step explanation:

The corresponding segments are proportional, so you can write any of several equations relating the different segment lengths. Here's one way:

  top segment/bottom segment = x/(x+5) = (x-2)/(x+1)

Multiply by the product of denominators:

  (x +1)x = (x +5)(x -2)

  x² +x = x² +3x -10 . . . . . eliminate parentheses

  10 = 2x . . . . . . . . . . . . . . add 10 -x -x² to both sides of the equation

  5 = x . . . . . divide by 2

in circle o, points a and b lie on the circle such that OA=5x-11 and OB=4(x-1) what represents the length of the circle' s diame
AysviL [449]
We know that
if <span>points a and b lie on the circle  and O is the center
so
OA is the radius
OA=OB
5x-11=4(x-1)-----> 5x-11=4x-4----> 5x-4x=11-4-----> x=7
OA=5x-11-------> OA=5*7-11-----> OA=24  units

the diameter is (OA+OB)
2*OA------> 2*24------> 48 units</span>

A toy company produces 1,000 toys per month. In January, 75 toys did not meet quality standards. The toy company generates a ran
erik [133]
Based on this sample, 100 toys will not meet standards.

There is 1 value that is 75 or lower in this simulation.  This makes the experimental probability 1/10.  1/10(1000) = 100 toys for the month.

Please help with this geometry question
Andrew [12]

It has been proven that of all line segments drawn from a given point not on it, the perpendicular line segment is the shortest.

<h3>How to prove a Line Segment?</h3>

We know that in a triangle if one angle is 90 degrees, then the other angles have to be acute.

Let us take a line l and from point P as shown in the attached file, that is, not on line l, draw two line segments PN and PM. Let PN be perpendicular to line l and PM is drawn at some other angle.

In ΔPNM, ∠N = 90°

∠P + ∠N + ∠M = 180° (Angle sum property of a triangle)

∠P + ∠M = 90°

Clearly, ∠M is an acute angle.

Thus; ∠M < ∠N

PN < PM (The side opposite to the smaller angle is smaller)

Similarly, by drawing different line segments from P to l, it can be proved that PN is smaller in comparison to all of them. Therefore, it can be observed that of all line segments drawn from a given point not on it, the perpendicular line segment is the shortest.
