Answer:

89%

Step-by-step explanation:

500-55=445

445/500=0.89

0.89x100=89

$500- $55= $445

445/500 = 89/100

89/100 × 100/1= 89%

Answer: 89%

Answer:

0.48.

Step-by-step explanation:

There are 2 ways that a tail lands once:-

Tail + head or

head + tail.

Prob(Tail on one throw) = 0.4

Prob(Head on one throw) = 1 - 0.4 = 0.6.

Prob(Tail first then head) = 0.4 * 0.6 = 0.24

Head then tail has the same probability (0.6*0.4).

So the requred probability = 0.24 + 0.24

= 0.48.

If the value of a and e is 5 and 4, then the value of b is 3. Then the equation of the ellipse will be given below.

[tex]\rm \dfrac{x^2 }{25} +\dfrac{y^2}{9} = 1[/tex]

Ellipse is a locus of a point that moves in a plane such that the sum of its distances from the two points called foci adds up to a constant. It is taken from the cone by cutting it at an angle.

The vertices (±5,0) and foci (±4,0) are given. Then the equation of the ellipse will be

We know that the general equation of the ellipse will be

[tex]\rm \dfrac{x^2 }{a^2} +\dfrac{y^2}{b^2} = 1[/tex]

Then the value of a will be

a = 5

And the value of the eccentricity will be

e = 4/5

Then the value of the b will be

[tex]\rm b^2 = a^2 - a^2e^2\\\\b^2 = 5^2 - 5^2 \times \dfrac{4^2}{5^2}\\\\b^2 = 25 - 16\\\\b \ = 3\\[/tex]

Then the equation will be

[tex]\rm \dfrac{x^2 }{5^2} +\dfrac{y^2}{3^2} = 1\\\\\rm \dfrac{x^2 }{25} +\dfrac{y^2}{9} = 1[/tex]

Using the relation between velocity, distance and time, it is found that the expression for the total time is given by:

[tex]t = \frac{9}{2x}[/tex]

Velocity is distance divided by time, that is:

[tex]v = \frac{d}{t}[/tex].

Denise bikes 3 miles to her friend's house, hence:

[tex]v_1 = \frac{3}{t_1}[/tex]

[tex]t_1 = \frac{3}{v_1}[/tex]

The average rate biking to her friend's house is twice the average rate coming home, hence, on the return, [tex]v_2 = 0.5v_1[/tex]:

[tex]v_2 = \frac{3}{t_2}[/tex]

[tex]t_2 = \frac{3}{v_2}[/tex]

[tex]t_2 = \frac{3}{0.5v_1}[/tex]

[tex]t_2 = \frac{6}{v_1}[/tex]

The total time is given by, considering [tex]v_1 = 2v_2 = 2v = 2x[/tex], as we want to consider x the rate coming home:

[tex]t = t_1 + t_2[/tex]

[tex]t = \frac{3}{2x} + \frac{6}{2x}[/tex]

The probability of getting the green apple is 7/20 option (B) 7/20 is correct.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

P(red) = 2/5

P(yellow) = 1/4

The sum of the probability of the event is 1.

P(red) + P(yellow) + P(green) = 1

2/5 + 1/4 + P(green) = 1

P(green) = 1 - (2/5 + 1/4)

P(green) = 7/20

Thus, the probability of getting the green apple is 7/20 option (B) 7/20 is correct.

Explanation:

3/6 = 1/2 of the numbers on the cube are even (2,4,6)

If we wanted both cubes to show an even number, then this comes up (1/2)*(1/2) = 1/4 of the time.

There are 6*6 = 36 outcomes total, so there are (1/4)*36 = 9 outcomes when both dice show an even number.

---------

Those nine outcomes are listed below

You probably have noticed that A has 3 choices (2,4,6) and so does B. That gives 3*3 = 9 outcomes total. This is an alternative pathway compared to the previous section.

[tex] \text{Height Of The Tree}[/tex]

[tex] \text{Let The Height of the Tree be ‘x’}[/tex]

We Know:-

[tex] \tan\theta = \frac{ \text{perpendicular}}{ \text{base} }[/tex]

[tex] \tan \theta = \frac{ \text{height of the tree}}{ \text{length of the base}} \\ \\ \implies \tan30 = \frac{ \text{x}}{25} \\ \\ \implies \text{x }= 25 \times \tan30 \\ \\ \implies \text{x }= 25 \times 0.577 \\ \\ \implies \text{x} = 14.425 \\ \\ \implies \text{x} = 14.43[/tex]

[tex] \therefore \text{height of the tree(\text{x})} = \red{14.43 \: \text{feet}}[/tex]

Option C is the correct answer

Answer: 25

Step-by-step explanation: Add all of the marbles, which is 20 in total, it is 5/20, so the ratio is 5:20

5:20 is 10:40, 15:60, 20:80, and 25:100

The answer is correct because 5:20 is 25% and 25/100 is also 25%

[tex]~~~~~~(8x-17)+(3x+2)+63 = 180\\\\\implies 11x +48=180\\\\\implies 11x = 180-48\\\\\implies 11x = 132\\\\\implies x= \dfrac{132}{11}\\\\\implies x= 12[/tex]

Answer:

x = 12.

Step-by-step explanation:

The sum of the 3 angles is 180, so:

8x - 17 + 3x + 2 + 63 = 180

11x -15 + 63 = 180

11x = 180  + 15 - 63

11x = 132

x = 132/11 = 12
