Answer:

1/7

Step-by-step explanation:

Heads: 1/2

Accomplished: 14 letters

Accomplished: 4 vowels

P(vowel) = 4/14 = 2/7

P(H and vowel) = 1/2 * 2/7 = 1/7

Final answer:

The probability of tossing a head and then selecting a vowel from the word 'accomplishment' is 3/28 or approximately 0.107.

Explanation:

The question asks us to find the probability of getting a head on a coin toss and then picking a vowel from the word 'accomplishment'. First, we determine each probability separately. The probability of getting a head when tossing a fair coin is 1/2, as there are two outcomes (head or tail), and getting a head is one of them.

The word 'accomplishment' has 14 letters, of which 3 are vowels (a, o, i). Therefore, the probability of picking a vowel at random from 'accomplishment' is 3/14. To find the combined probability of both events happening in sequence (tossing a head then picking a vowel), we multiply the probabilities of the individual events: (1/2) * (3/14) = 3/28 or approximately 0.107.

Answer:

y=-65/9

Step-by-step explanation:

12(5+2y)=4y-(5-9y)

60+24y=4y-5+9y

60+24y=13y-5

60+24y-13y=-5

60+9y=-5

9y=-5-60

9y=-65

y=-65/9

The value of y that satisfies the equation is y = -65/11.

The equation is given as follows:

12(5+2y) = 4y - (5 - 9y)

To find the value of y that satisfies the equation, we can solve for y by simplifying the equation.

Given equation:

12(5 + 2y) = 4y - (5 - 9y)

First, let's simplify both sides of the equation:

60 + 24y = 4y - 5 + 9y

Next, let's combine like terms:

24y - 4y - 9y = -5 - 60

Simplifying further:

11y = -65

Finally, divide both sides of the equation by 11 to solve for y:

y = -65/11

Therefore, the value of y that satisfies the equation is y = -65/11.

Answer:

One-sixth x + 47

1 and two-thirds x + 35 minus 1 and one-half x + 12

1 and one-third x + 35 minus 1 and one-half x minus 12

Step-by-step explanation:

The original expression in this problem is

[tex]5(\frac{1}{3}x+7)-3(\frac{1}{2}x-4)[/tex]

We start by applying the distributive property and multiplying each factor outside the brackets by each factor inside:

[tex]5\cdot \frac{1}{3}x+5\cdot 7 -3\cdot \frac{1}{2}x+3\cdot 4[/tex]

So we get:

[tex]\frac{5}{3}x+35-\frac{3}{2}x+12[/tex]

Now we can rewrite this using mixed fractions:

[tex]1\frac{2}{3}x+35-1\frac{1}{2}x+12[/tex] (1)

Which can be also written as

[tex]1\frac{2}{3}x+35-(1\frac{1}{2}x-12)[/tex] (2)

And finally, by solving it, we find

[tex]\frac{1}{6}x+47[/tex] (3)

So the three correct options are

One-sixth x + 47

1 and two-thirds x + 35 minus 1 and one-half x + 12

1 and one-third x + 35 minus 1 and one-half x minus 12

Answer:

25

Step-by-step explanation:

Solving the inequality

x - 3 ≥ 2 ( add 3 to both sides )

x ≥ 5

Thus the least value of x is x = 5, hence

least possible value of 5x = 5(5) = 25

Final answer:

The least possible value of 5x, when x-3≥2, is 25, as x must be at least 5, and 5x equals 25 when x is 5.

Explanation:

The student's question asks to find the least possible value of 5x given the inequality x-3≥2. To solve this, we first find the smallest value of x that satisfies the inequality. We add 3 to both sides of the inequality to isolate x, obtaining x≥3+2, which simplifies to x≥5. Therefore, the smallest value of x is 5. Now, we multiply this value by 5 to find the least possible value of 5x, which is 5×5=25.

Answer:

[tex]x=27[/tex]

Step-by-step explanation:

Solve for x

Combine like terms

[tex](3x+99)^o=180^o[/tex]

subtract 99 both sides

[tex]3x=180-99\\3x=81[/tex]

Divide by 3 both sides

[tex]x=27[/tex]

Final answer:

The total distance from the beginning of the first house's lawn to the end of the third house's lawn is 1050 feet. This calculation is done by adding the length of the first house's lawn (300 feet), the second house's (250 feet), and double the second's lawn for the third house's (500 feet).

Explanation:

To calculate the total length of the lawns from the first to the third house, we first determine the length of each lawn individually and then add them together:

The first house has a lawn that is 300 feet long.

The second house has a lawn that is 50 feet shorter than the first lawn, so it is 300 - 50 = 250 feet long.

The third house has a lawn that is twice the length of the second house's lawn, so it is 2 × 250 = 500 feet long.

Add the lengths of the three lawns together to find the total distance from the beginning of the first house's lawn to the end of the third house's lawn:

300 feet + 250 feet + 500 feet = 1050 feet

Therefore, it is 1050 feet from the beginning of the first house's lawn to the end of the third house's lawn.

Final answer:

By dividing the total hours of bike use (8 hours) by the total cost ($42), you find that a customer gets approximately 0.19 hours of bike use per dollar when renting a bike at Keller's Bike Rentals, rounded to the nearest hundredth.

Explanation:

To determine how many hours of bike use a customer gets per dollar at Keller's Bike Rentals, we need to perform a simple division calculation using the information provided. The total cost of renting a bike for 8 hours is $42.

Dividing the total hours of bike use by the total cost gives us the hours of bike use per dollar:

Hours per dollar = Total hours of bike use / Total cost

Hours per dollar = 8 hours / $42

Now, we perform the division:

Hours per dollar = 0.19047619...

When rounded to the nearest hundredth, this is approximately 0.19 hours per dollar.

Answer:

2.62 seconds

Step-by-step explanation:

Let

t ----> the time in seconds

h(t) ----> he height of the ball, in feet

we have

[tex]h(t)=-16t^2+40t+5[/tex]

we know that

When the ball hits the ground, the height is equal to zero

so

[tex]-16t^2+40t+5=0[/tex]

The formula to solve a quadratic equation of the form

[tex]at^{2} +bt+c=0[/tex]

is equal to

[tex]t=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}[/tex]

in this problem we have

[tex]-16t^2+40t+5=0[/tex]

so

[tex]a=-16\\b=40\\c=5[/tex]

substitute in the formula

[tex]t=\frac{-40\pm\sqrt{40^{2}-4(-16)(5)}} {2(-16)}[/tex]

[tex]t=\frac{-40\pm\sqrt{1,920}} {-32}[/tex]

[tex]t=\frac{-40+\sqrt{1,920}} {-32}=-0.12\ sec[/tex]

[tex]t=\frac{-40-\sqrt{1,920}} {-32}=2.62\ sec[/tex]

Answer:

148/15 or 9 13/15

Step-by-step explanation:

7 2/3 + 2 1/5

7 2/3 needs to be translated into a bigger fraction by taking 7 and multiplying it with the denominator and then adding onto the numerator.

7 2/3 = 23/3

The same goes for 2 1/5.

2 1/5 = 11/5

Now we have 23/3+11/5 so we need to find a common denominator which would be fifteen.

23/3 + 11/5

23/3 x 5/5 = 115/15

11/5 x 3/3 = 33/15

115/15 + 33/15 = 148/15

The value of 7 2/3 + 2 1/5 is 9 13/15

The lowest common multiple of 3 and 5 is 15. Therefore, 7 2/3 + 2 1/5 will be calculated thus:

= 7 2/3 + 2 1/5

= [7 + 2/3× 15] + [2 1/5 × 15]

= 7 10/15 + 2 3/15

= 9 13/15

In conclusion, the value of the fraction 7 2/3 + 2 1/5 is 9 13/15

Answer:

  A. just as it leaves the bat

Step-by-step explanation:

It depends on the assumptions you make.

If you assume that the speed is reduced by air resistance, and that the hit is a fly ball, then the speed begins to slow as soon as the ball leaves the bat. Its maximum speed will be just as it leaves the bat.

__

If you assume no air resistance and that the ball takes 1 second to reach the ground, the speed will be a maximum just as the ball hits the ground, a second after it leaves the bat.

__

If you assume no air resistance and that the ball takes 2 seconds to reach the ground, the speed will be a maximum just as the ball hits the ground, two seconds after it leaves the bat.

__

Depending on the nature of the pitch and the hit (and the assumptions you make about energy loss and gain), the maximum speed may be as the ball leaves the pitcher's hand, or just as the ball hits the bat.

__

My guess is that the assumptions listed for the first case are the ones you're most likely expected to use. The answer above reflects that choice.

[tex]$212960\div1000=\frac{212960}{1000}[/tex]

Here, we have 3 zeros in the denominator.

So, the decimal point is move 3 digit to the left of the last digit.

[tex]$212960\div1000=212.96[/tex]
