Answer:

126468 is the result of 27 multiplied by 4684

Answer:

7/9

Step-by-step explanation:

Given:

Number of yellow cards=2

Number of red cards=12

Number of blue cards=4

Total number of cards= Number of yellow cards+Number of red cards+Number of blue cards

= 2+4+12=18cards

Probability of a NON-blue card = number of non blue/ total number

where NON-blue= Number of red cards+

Number of yellow cards

= 2+12=14

P(not blue)=

=14/18

7/9

Therefore, probability that the card is not blue is 7/9

Answer:

12

Step-by-step explanation:

Since the x values are the same, we only have to look at the difference between the y values

6 - -6

6+6

12

The distance is 12

Answer:

[tex]\Huge \boxed{12}[/tex]

Step-by-step explanation:

To find the distance between two points, apply the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+ (y_2-y_1)^2 }[/tex]

Plug in the values.

[tex]d=\sqrt{(1-1)^2+ (6-(-6))^2 }[/tex]

Evaluate.

[tex]d=\sqrt{(0)^2+ (12)^2 }[/tex]

[tex]d=\sqrt{144}[/tex]

[tex]d=12[/tex]

Answer:

12.53 miles

Step-by-step explanation:

6² + 11² = x²

36 + 121 = x²

157 = x²

x = 12.53 miles

The distance from town A to town C would be; 12.53 miles.

A numerical expression is an algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

We are given that Town B is 6 miles due north of town A, and town C is due east of town A. It is 11 miles from town B to town C.

Therefore,

6² + 11² = x²

36 + 121 = x²

157 = x²

x = 12.53 miles

Hence, the distance from town A to town C would be; 12.53 miles.

Answer:

(4x + 5)(x² + 25)

Step-by-step explanation:

Given

4x³ + 5x² + 100x + 125 ( factor the first/second and third/fourth terms )

= x²(4x + 5) + 25(4x + 5) ← factor out (4x + 5) from each term

= (4x + 5)(x² + 25)

Answer:

  A.  4.11 units

Step-by-step explanation:

It can be convenient to put one of these equations into general form, then use the formula for the distance from a point to a line.

In general form, the first equation is ...

  3x -y +9 = 0

So, the distance from a point to that line is ...

  ax +by +c = 0 . . . . . . equation of a line

  d = |ax +by +c|/√(a^2+b^2) . . . corresponding distance formula

  d = |3x -y +9|/√(3^2 +(-1)^2)

Using the y-intercept of the other line as the point of interest, we find its distance to the first line to be ...

  d = |3(0) -(-4)+9|/√10 = 13/√10 ≈ 4.11

The distance between the lines is about 4.11 units.

_____

Unless the lines are vertical or horizontal, you know the distance will be less than the difference between the x- or y- intercepts. Here, the y-intercepts are separated by 9-(-4) = 13 units. The x-intercepts are -3 and 4/3, so are separated by 4 1/3 units. Any answer choice larger than 4.33 cannot be correct.

Answer:

Negative nonlinear association

Answer:

D is wrong

Step-by-step explanation:

I followed advice of a person above me and got it wrong on test. I now realise that the only logical and correct answer is C

Answer: -1^0 because any number to the 0 is 1

-1^1 because it stays the same number which is negative

Answer:

Hey there!

For question number 1.

(-1)^2, because this equals (-1)(-1), or 1.

For question number 2.

(-1)^3, becuase this equals (-1)(-1)(-1), or -1.

Answer:

C

Step-by-step explanation:

Here in this question , we are interested in calculating the total distance covered by the train in the 10 minutes that it ran.

From the first part of the question, we already know the distances in the first 5 minutes.

Now, to calculate the total distance in the second 5 minutes, we use the distance formula since we have the average speed and the time;

Mathematically; Total distance = average speed * time

From the question, average speed is 33km/h, while time is 5 minutes. To achieve a consistent unit, we convert 5 minutes to hours.

That would be 5/60 = 1/12 hours

So the total distance in the second 5 minutes is;

33 * 1/12 = 2.75 km

Now, to calculate the total distance traveled, let’s add up the distances in the first 5 minutes and convert to kilometers;

That would be;

68 + 127 + 208 + 312 + 535 = 1,250 m

Let’s convert this to km.

We simply divide by 1000 = 1250/1000 = 1.25 km

The total distance is thus ;

1.25 + 2.75 = 4 km

Answer:

B. 90°

Step-by-step explanation:

Quadrilateral inscribed in the circle with center O is a cyclic quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

Therefore,

(b + d) + (32° + 58°) = 180°

b + d + 90° = 180°

b + d = 180° - 90°

b + d = 90°

Answer:

Step-by-step explanation:

The midpoint M of a line segment can be found by using the formula

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

G(-3,0) and H(11,- 4)

Their midpoint is

We have the final answer as

Hope this helps you

You use a compass to draw an arc (or a full circle). The radius must be kept the same so that you can copy the length of the segment properly. If the compass could move freely, then it is unlikely the arc will be a piece of a circle, and rather some squiggly curve. So this is why the compass width must be locked into place.

Answer:

You have:

2 red tins

3 white tins

This equals 5 tins of paint.

If you multiply 5 tins by 3 times it will give you 15 tins of paint.

Now: 2 red tins x 3 = 6 red tins

3 white tins x 3 = 9 white tins

6 red tins + 9 white tins = 15 tins of paint

Answer:

She will need 6 tins of Red paint

Answer:

[tex] \boxed{ \bold{ \huge{ \bold{w = 5}}}}[/tex]

Option D is the correct option

Step-by-step explanation:

[tex] \sf{8 + \frac{35}{w} = 15}[/tex]

⇒[tex] \sf{ \frac{8 \times w + 35}{w} = 15}[/tex] { w ÷ 1 = w , So, I wrote 8 × w }

⇒[tex] \sf{ \frac{8w + 35}{w} = 15}[/tex]

Apply cross product property

⇒[tex] \sf{8w + 35 = 15w}[/tex]

Move 15w to left hand side and change it's sign

Similarly, Move 35 to right hand side and change it's sign

⇒[tex] \sf{8w - 15w = - 35}[/tex]

Collect like terms

⇒[tex] \sf{ - 7 w = - 35 }[/tex]

Divide both sides of the equation by -7

⇒[tex] \sf{ \frac{ - 7w}{ - 7} = \frac{ - 35}{ - 7} }[/tex]

Calculate

⇒[tex] \sf{w = 5}[/tex]

Hope I helped!

Best regards!!

Answer:

w = 5

Step-by-step explanation:

8 + [tex]\frac{35}{w}[/tex] = 15

subtract 8 from both sides

8 +  [tex]\frac{35}{w}[/tex] - 8 = 15 - 8

simplify

[tex]\frac{35}{w}[/tex] = 7

35/7 = w

w = 5

Answer:

round up the number

Step-by-step explanation:

Answer:

Step-by-step explanation:

An Additive Verse is a pair of numbers whose sum is zero.

Example: the additive Inverse of -5 is +5

Therefore: the Additive Inverse of -10 1/4 would be +10 1/4

Given : f(x) = 3x + 10 and g(x) = x - 2

To Find : f(g(5))

[tex]:\implies\sf\:g(x) = x-2[/tex]

[tex]:\implies\sf\:g(5) = 5-2[/tex]

[tex]:\implies\bf\:g(5) = 3[/tex]

Now,

[tex]:\implies\sf\:f(x)=3x+10[/tex]

[tex]:\implies\sf\:f(g(5))=3x+10[/tex]

[tex]:\implies\sf\:f(3)=3(3)+10[/tex]

[tex]:\implies\sf\:f(3)=9+10[/tex]

[tex]:\implies\boxed{\bf{\blue{f(3)=19}}}[/tex]

Answer:

Intensity = 2500/x^2

6.25 lumem

5 Feets

Step-by-step explanation:

Given the following :

Area (A) = 0.1x^2

Intensity, Energy and Area are related by the formular :

Intensity = power / Area

A) If 250 lumens of light energy is produced :

Intensity (I) = 250 / 0.1x^2

Intensity = 2500/x^2

x = distance

B) USING THE EQUATION :

1) What is the intensity of light on an object that is 20 feet from the spotlight source?

x = 20

Intensity = 2500/x^2

Intensity = 2500/20^2

Intensity = 2500/400

Intensity = 6.25 lumen

11) How far from the spotlight is an object that recieves 100 lumens of light per square foot?

Intensity = 100

100 = 2500 / x^2

100x^2 = 2500

x^2 = 2500/ 100

x^2 = 25

x = 5 Feets
