A bag contains 1 yellow ball and 9 red balls. A ball is chosen at random from the bag. What is the BEST answer for the probability of drawing the yellow ball?
A) impossible
B) unlikely
C) very likely
D) certain

Answer:

3 hours

Step-by-step explanation:

We have the amount of miles that Tanika passed, 189 miles. We also have the speed at which Tanika was driving, 63 miles per hour. Basically, Tanika was passing 63 miles on every one hour of driving. In order to find out how much time was Tanika driving with that speed to pass those miles, we just simply need to divide the miles passed with the speed of driving:

189 / 63 = 3

So we have a result of 3, thus Tanika needed three hours with a speed of 63 miles per hour to pass 189 miles.

Question 1:

For this case we can raise a rule of three:

63 miles ---------------> 1 hour

189 miles -------------> x

Where "x" represents the number of hours it takes Tanika to travel 189 miles.

[tex]x = \frac {189 * 1} {63}\\x = 3[/tex]

So, Tanika takes 3 hours to travel 189 miles

Answer:

Three hours

Question 2:

For this case we must solve the following equations:

A) [tex]-2x <4[/tex]

Dividing between -2 on both sides of the inequality:

[tex]x <\frac {4} {- 2}\\x <-2[/tex]

B) [tex]5t + 7 <32[/tex]

We subtract 7 on both sides of the inequality:

[tex]5t <32-7\\5t <25[/tex]

Dividing between 5 on both sides of the inequality:

[tex]t <\frac {25} {5}\\t <5[/tex]

C) [tex]12s-17 \geq2s + 33[/tex]

We subtract 2s on both sides of the inequality:

[tex]12s-2s-17 \geq33\\10s-17 \geq33[/tex]

We are 17 on both sides of the inequality:

[tex]10s \geq33 + 17\\10s \geq50[/tex]

We divide between 10 on both sides of the inequality:

[tex]s \geq \frac {50} {10}\\s \geq5[/tex]

D) [tex]-8m> -24[/tex]

Dividing between -8 on both sides of the inequality:

[tex]m> \frac {-24} {- 8}\\m> 3[/tex]

E) [tex]8n + 7> 4n + 35[/tex]

Subtracting 4n on both sides of the inequality:

[tex]8n-4n> 35-7\\4n> 28[/tex]

Dividing between 4 on both sides of the inequality:

[tex]n> \frac {28} {4}\\n> 7[/tex]

Answer:

[tex]x <-2\\t <5\\s \geq5\\m> 3\\n> 7[/tex]

Answer:

y = (-1/4)x + 4 is the equation of the line in slope-intercept form.

Step-by-step explanation:

When graphing the line I like to do it from left to right. Start at the point (0,4) which is the y-intercept as a coordinate. Slope is rise over run so now go down 1 unit and 4 units to the right. Keep doing that pattern and then connect the points to form a line. Make sure to put arrows on the ends to represent that the line goes on forever in both directions. Going right to left you could go up 1 unit and 4 units to the left as well. I hope this helps.

y = (-1/4)x + 4 is the equation of the line in slope-intercept form.

A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. On the y-axis, this value c is referred to as the intercept. Key Concept. Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.

Given

m = -1/4

c = 4

y = mx+c

y = -1/4 x + c

The dependent variable is distance, the equation is y = 35x, and the dragonfly will travel 840 miles

Step-by-step explanation:

By the graph it can be seen that the distance a dragonfly can travel is dependent on the certain number of hours.

∴ Dependent variable  : Distance (on y axis)

The equation of straight line is given by :-

, here m is the slope of the line and c is the initial value of y at x=0.

From the given graph, the slope of the given line passing from (0,0) and (2,70) will be :-

Also, the value of y = 0 at x=0.

∴ The equation of the given line :

At x=24,  

∴  The dragonfly will travel 840 miles in 24 hours.

Because you are told the two are similar, find the ratio of them.

Side AB = ft and side EF is 25 feet.

This means the larger rectangle is 5 times larger ( 25 /5 = 5).

The answer is:

The x-coordinate of the solution to the system of equations is:

[tex]x=-2[/tex]

We can solve the problem writing both equations as a system of equations.

So, we are given the equations:

[tex]\left \{ {{y=x+4} \atop {3y=-2x+2}} \right.[/tex]

Then, solving by reduction we have:

Multiplying the first equation by 2 in order to reduce the variable "x", we have:

[tex]\left \{ {{2y=2x+2*4} \atop {3y=-2x+2}} \right.[/tex]

[tex]5y=2x-2x+8+2\\\\5y=8+2\\\\y=\frac{10}{5}=2[/tex]

Now, substituting "y" into the first equation, to isolate "x" we have:

[tex]y=x+4\\\\2=x+4\\\\x=2-4=-2[/tex]

Hence we have that the x-coordinate of the solution to the system of equations is

[tex]x=-2[/tex]

Have a nice day!

Answer:

The x coordinate of the solution is -2

Step-by-step explanation:

* To find the x-coordinate of the solution to the system of the

  equations y = x + 4 and 3y = -2x + 2 solve the equations by the

  substitution method

- In the substitution method we substitute one of the two variables

 by the other to make an equation of one variable

∵ y = x + 4 ⇒ (1)

∵ 3y = -2x + 2 ⇒ (2)

- Substitute the value of y in equation (2) by the value of y in equation (1)

∵ The value y = 4 + x in the equation (1)

- Put this value of y in the equation (2)

∴ 3(x + 4) = -2x + 2 ⇒ open the bracket

∴ 3x + 12 = -2x + 2 ⇒ subtract 12 from both sides

∴ 3x = -2x - 10 ⇒ add 2x to both sides

∴ 5x = -10 ⇒ divide both sides by 5

∴ x = -2

* The x coordinate of the solution is -2

Answer:

x = +√96 = +√(16*6) = + 4√6

Step-by-step explanation:

Note that this is a large triangle with 2 smaller, similar triangles inside.  The base of the large triangle is 10, so the base of either of the smaller triangles is half that, or 5.  These are all right triangles.  We can now apply the Pythagorean Theorem to find x.

According to this Theorem, x² + 5² = 11², so that x² = 121 - 25 = 96.

Taking the positive square root to be the desired side length x,

x = +√96 = +√(16*6) = + 4√6

The answer is $9.56.

The volume of a sports ball with a diameter of 29 cm can be calculated using the formula for the volume of a sphere, resulting in approximately 12,719 cubic centimeters for its volume.

The volume of a sphere (such as a sports ball) can be determined using the formula V = 4/3πr³, where V represents volume and r represents the radius of the sphere. In the situation you described, the sports ball has a diameter of 29 cm which means the radius (r) is half of that or 14.5 cm. Plugging these values into the formula gives us:

V = 4/3π(14.5)³ ≈ 12,718.951 cm³

So, the volume of the sports ball is approximately 12,719 cubic centimeters.
