Answer:

4/9

Step-by-step explanation:

The probability that the spinner lands on a 5 or a multiple of 3 will be 0.4444 or 44.44%.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

You spin a spinner with 9 equal spaces numbered 1 through 9.

Then the probability that the spinner lands on a 5 or a multiple of 3 will be

The total number of the event will be

Total events = 9

The favorable event will be

Favorable = 1 {5} and 3 {3, 6, 9}

Then the probability will be

P = 1/ 9 + 3/ 9

P = (1 + 3) / 9

P = 4/9

P = 0.4444

P = 44.44%

Answer:

Triangle 2

Step-by-step explanation:

The translation is a type of transformation, where the figure is just translated or simply moved from its original place.

The figure is not rotated or dilated but simply moved.

Here, we can see that only figure or triangle 2 is like the triangle ABC. Other triangles have undergone other transformations.

So, the correct answer is triangle 2.

Answer: (below)

Step-by-step explanation:

The functions shown are exponential functions, which have the form f(x) = a*(b)^x. "a" represents the intial value, while "b" represents the growth factor.

To determine whether a function is growing or decaying, you look at the growth factor. If the growth factor is greater than 1, the function is growing, since each value is getting larger and larger. Meanwhile, if the growth factor is between 0 and 1, the function is decaying, since each value is getting smaller and smaller.

Now, back to this question, let's look at our functions. In the function on the left, the growth factor is 0.87, which is between 0 and 1, so this function is decaying. For the function on the right, the growth factor is 1.25, which is greater than 1, so this function is decaying. Next, let's look at our graphs. In the left graph, the function is growing, so it matches with the function on the right. Meanwhile, in the right graph, the function is decaying, so it matches with the function on the left.

Answer:

Angle #4

Step-by-step explanation:

4 & 5 are equal, and opposite.

1 & 2 are also congruent by this standard.

Answer:

(-2, -1)

Step-by-step explanation:

The centre of a circle is located at the mid-point of any diameter, hence we take the average of the coordinates of the end-points.

Cx = (2-6)/2 = -2

Cy = (6-8)/2 = -1

So the centre is located at (-2, -1)

Answer:

C is the answer of this question

we assume the height of the triangle is x,

so the base length will be x+4

the triangle area will be area = 1/2 ( base * height)

48 = 1/2 (x + 4) x

96 = x2 + 4x

96 + 4 = x2 + 4x + 4

100 = (x + 2)2

10 = x + 2 (for the square 100, we ignore the -10, minus is meaningless in length )

x = 8

x + 4 = 8 + 4 = 12

so the height for the triangle is 8 unit, base is 12 unit,

Answer:

Joe Will need to pay a commission of [$7.50]. The Total amount Charged by the broker will be [$17.50]

Step-by-step explanation:

Joe will need to pay a commission of [tex]\$7.50[/tex] and Total amount charged by broker will be [tex]\$17.50[/tex].

Commission is a form of money pay as remuneration for services rendered or products sold.

We have,

Joe's current portfolio  [tex]=\$ 50,000[/tex]

Price of one stock [tex]=\$15[/tex]

So,

As his portfolio is less than [tex]\$100,000[/tex], he have to pay [tex]15\%[/tex] and [tex]\$10[/tex] trade fee,

So,

Price of [tex]50[/tex] shares [tex]=50*15=\$750[/tex]

Commission charge [tex]=1\%\ of\ 750[/tex]

                                  [tex]=\$7.5[/tex]

So, commission of [tex]\$7.5[/tex] will be paid.

So,

Total amount charged by Broker [tex]=10+7.5=\$17.5[/tex]

Hence, we can say that Joe will need to pay a commission of [tex]\$7.50[/tex] and Total amount charged by broker will be [tex]\$17.50[/tex].  .

Answer:

13.95 cm

Step-by-step explanation:

the volume of the cone =

⅓× π r². h = 180 π

⅓×π r²×15 = 180 π

(eliminate π)

=> 5r² = 180

r² = 180/5 = 36

r=√36 = 6 cm

the volume of the sand = ½×4/3 π r³

= ⅔× π ×6³ = 144π cm³

the ratio of the volume :

144π/180π = 0.8

so the value of h = ³√0.8 x 15 = 0.93× 15

= 13.95 cm

Answer:

(a) x = [tex]128^{o}[/tex]

(b) x = [tex]74^{o}[/tex]

Step-by-step explanation:

A. sum of angles in a polygon = (n - 2) 180

The polygon given is an irregular pentagon, where n = 5

So that;

sum of angles in a pentagon = (5 - 2) 180

                        = 3 x 180

                        = [tex]540^{o}[/tex]

Thus,

x + 90 + 76 + 110 + 136 = [tex]540^{o}[/tex]

x + 412 = [tex]540^{o}[/tex]

x = [tex]540^{o}[/tex] - 412

x = [tex]128^{o}[/tex]

B. The polygon given is an irregular pentagon, where n = 5.

Let the supplementary angle with angle 38 be represented by y,

y + 38 = 180

y = 180 - 38

  = [tex]142^{o}[/tex]

y = [tex]142^{o}[/tex]

Let the supplementary angle with x be represented by z, so that;

z + 72 + 120 + 100 + 142 = [tex]540^{o}[/tex]

z + 434 = [tex]540^{o}[/tex]

z = [tex]540^{o}[/tex] - 434

  = [tex]106^{o}[/tex]

z = [tex]106^{o}[/tex]

But, x + z = [tex]180^{o}[/tex]

Then;

x + [tex]106^{o}[/tex] = [tex]180^{o}[/tex]

x = [tex]180^{o}[/tex] - [tex]106^{o}[/tex]

  = [tex]74^{o}[/tex]

x = [tex]74^{o}[/tex]
