You would divide 21 by 3.14

Which would give you 6.687 now round up to the nearest hundredth

Misha Larkins [42]

Answer:

756.29

Step-by-step explanation:

2.04 x 105 = 214.2

and 9.07 x 107 = 970.49

970.49 - 214.2 = 756.29

What is the value of x for which m || n?<br> x = 40<br> x = 5<br> x = 105<br> x = 30

QveST [7]

Answer:

(A) x=40

Step-by-step explanation:

Given: It is given that m is parallel to n.

To find: The value of x.

Proof: It is given that m is parallel to n, from the figure it can be seen that 105° and (3x-15)° forms alternate exterior angles which are equal in measure because m is parallel to n.

Thus, $105^{\circ}=3x-15^{\circ}$

⇒ $105^{\circ}+15^{\circ}=3x$

⇒ $120^{\circ}=3x$

⇒ $\frac{120}{3}=x$

⇒ $x=40$

Thus, the value of x is 40, hence option A is correct.

Item 1 A bag contains 7 blue cards, 4 green cards, 6 red cards, and 8 yellow cards. You randomly choose a card. a. How many poss

egoroff_w [7]

Answer:

4 possible outcomes

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

so

Let

x------> size of the event space

y-----> size of the sample space

so

$P=\frac{x}{y}$

In this problem

<em>The probability of choose a blue card is </em>

$x=7$

$y=7+4+6+8=25$

substitute

$P=\frac{7}{25}$

<em>The probability of choose a green card is </em>

$x=4$

$y=7+4+6+8=25$

substitute

$P=\frac{4}{25}$

<em>The probability of choose a red card is </em>

$x=6$

$y=7+4+6+8=25$

substitute

$P=\frac{6}{25}$

<em>The probability of choose a yellow card is </em>

$x=8$

$y=7+4+6+8=25$

substitute

$P=\frac{8}{25}$

The sum of the probabilities of the 4 possible outcomes is equal to

$\frac{7}{25}+\frac{4}{25}+\frac{6}{25}+\frac{8}{25}=\frac{25}{25}$ ----> represent the 100%

Which line represents the direct variation equation y = 1/2x?

Verdich [7]

Answer:

C.

Step-by-step explanation:

y = 1/ x must pass through the origin because when x = 0, y = 0.

So its either B or C.

A positive slope rises to the right ( 1/2 is positive), so its C.

You can also see that the slope of C is 1/2 because it passes through the points (0.0) and (2, 1).

Find an equation for the perpendicular bisector of the line segment whose endpoints are (8,-5)(8,−5) and (4,3)(4,3).

Marysya12 [62]

Answer:

$Correct answer\\y=\frac{1}{2} x-4$

Step-by-step explanation:

$y-\frac{-5+3}{2} =\frac{-1}{\frac{3-(-5)}{4-8} } (x-\frac{4+8}{2} )\\y+1=\frac{1}{2} (x-6)\\y=\frac{1}{2} x-4$
