Answer 1

Answer:

3/50

Step-by-step explanation:

3 g, 5 r, 2 o

3 + 5 + 2 = 10

Orange = 2 jelly beans

Probability of selecting an orange jelly bean: 2/10 or 1/5

If you put the jelly bean back in, there is still 10 jelly beans.

Green = 3 jelly beans

Probability of selecting a green jelly bean: 3/10

Multiply the probabilities:

1/5 x 3/10

= 3/50

Dilate this by 1/3

Answers

For this shape there are four points. The plotted ordered pairs are:
M = (3, 9)
N = (6, 0)
O = (3, 6)
P = (-3, 0)

All you have to do is multiply the BOTH x- and y-values by 1/3 on EACH ordered pair. And if it’s easier, you can divide by 3 as well. It’s the same thing.

M = (3, 9) = (3*1/3, 9*1/3) = (1, 3)
N = (6, 0) = (6*1/3, 0*1/3) = (2, 0)
O = (3, 6) = (3*1/3, 6*1/3) = (1, 2)
P = (-3, 0) = (-3*1/3, 0*1/3) = (-1, 0)

(1, 3) , (2, 0) , (1, 2) , and (-1, 0) are your points.

A ball is thrown from an initial height of 6 feet with an initial upward velocity of 17 ft/s. The ball's height h (in feet) after t seconds is given by the following.


h=6+17t-16t^2


Find all values of t for which the ball's height is 10 feet.


Round your answer(s) to the nearest hundredth.
(If there is more than one answer, use the "or" button.)
t=___seconds

Answers

Answer:

6 + 29t - 16t^2 = 18

16t^2 - 29t + 12 = 0

t = (29 +- √(29^2 - 4*12*16))/32

t = (29 +- √73)/32

t  = 0.639249882958827, 1.1732501170411

Step-by-step explanation:

The values of t for which the ball's height is 10 feet are approximately 0.71 seconds or 0.35 seconds

The given equation for the height of the ball is a quadratic equation, which is solved using the quadratic formula to find the values of t.

The quadrature formula for ax² + bx + c = 0 is:

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

Given that,

The initial height of the ball: 6 feet

The initial upward velocity of the ball: 17 ft/s

The equation for the ball's height after t seconds: h = 6 + 17t - 16t²

The goal is to find the values of t for which the ball's height is 10 feet.

To find the values of t when the ball's height is 10 feet,

Set the equation h = 10 and solve for t.

Plugging in the given equation h = 6 + 17t - 16t²

And substituting h with 10, we get:

10 = 6 + 17t - 16t²

Rearrange the equation to solve for t.

16t² - 17t + 4 = 0

To find the values of t, we can use the quadratic formula:

In this case,

a = 16,

b = -17, and

c = 4.

Plugging these values into the quadratic formula, we get:

[tex]t = \frac{17 \pm \sqrt{((-17)^2- 4 \times 16 \times 4)}}{2 \times 16}[/tex]

Simplifying this equation, we have:

[tex]t = \frac{(17 \pm \sqrt{(289 - 256)}}{32}[/tex]

[tex]t = \frac{(17 \pm \sqrt{33})}{32}[/tex]

t ≈ 0.710 or 0.351

Hence,

Rounding to the nearest hundredth, we get two possible values for t:

t ≈ 0.71 seconds or 0.35 seconds

11m^2

Step-by-step explanation:

So first it would probably help to split it into different shapes. then you find the area of those shapes and add them.  

36 + 45 + 30 = 111 m^2

The area would be 111m^2.
First I broke the figure into three pieces and I did 12x5 which is 60, then 10x3 which is 30. Add them together and get 90. Lastly, 7x3 is 21 so add 21+90 and this gets you the area of 111m.

How do you subtract mixed numbers?

Answers

You make the mixed number an improper fraction, then, if not already, make the two improper fractions have common denominators, then you subtract thresh two numerators to get your answer


For Example:

2 1/3 - 2 1/6 =

7/3 - 13/6 =

14/6 - 13/6 = 1/6

Answer:

Step-by-step explanation:

lets take 2[tex]\frac{2}{5}[/tex] - 1[tex]\frac{3}{10}[/tex]

you have to convert 2 into [tex]\frac{10}{5}[/tex] so it would be [tex]\frac{12}{5}[/tex]

you also have to convert 1 into [tex]\frac{10}{10}[/tex] so it would be [tex]\frac{13}{10}[/tex]

since the denominators and different were ganna have to make them the same by mutiplying

you can easily do 5x2 to get 10

since you multiplied by 2 on the bottom do it on the top and you will get [tex]\frac{24}{10}[/tex]

now subtract them [tex]\frac{24}{10}[/tex]-[tex]\frac{13}{10}[/tex]=[tex]\frac{11}{10}[/tex]

24-13=11 but you need to simplify it and make it [tex]1\frac{1}{10}[/tex]
