A package of 3 pairs costs $12.00. How much would you save if you buy 2 packages instead of 6 individual pairs? Choose all answers that are correct.
a.6 × 5 = 30, 2 ×12 = 24, and 30 – 24 = 6
b.12 – 5 = 7, 7 x 2 = 14, and 14 – 6 = 8
c.12 ÷ 3 = 4, 5 – 4 = 1, and 1 × 6 = 6
d.12 ÷ 3 = 4, 4 × 5 = 20, and 20 – 12 = 8

Physics students were modeling the height of a ball once it was dropped from the top of a 10 foot ladder. The
julsineya [31]

Answer:

<em>Interval notation: [0, 2.236]</em>

<em>Set Builder notation: </em>\{t\ |\ 0\le t\le 2.236\}

Step-by-step explanation:

Given that:

Equation of height of the ball dropped from a height of 10 foot, as:

h(t) = 10 - 2t^2

Where t is the time since the ball was dropped.

To find:

The domain of the function in Interval and set builder notation.

Solution:

<em>Domain of a function </em>is defined as the set of valid input values that can be given to the function for which the function is defined.

Here, input is time.

We can not have negative values for time.

Therefore, starting value for time will be <em>0 seconds</em>.

And the value of height can not be lesser than that of 0 ft.

0= 10 - 2t^2\\\Rightarrow 2t^2=10\\\Rightarrow t^2=5\\\Rightarrow t =2.236\ seconds

Maximum value for time can be 2.236 seconds.

Therefore the domain is:

<em>Interval notation: [0, 2.236]</em>

<em>Set Builder notation: </em>\{t\ |\ 0\le t\le 2.236\}

Greeley [361]

Answer:

144 children and 170 adults

Step-by-step explanation:

make 2 equations

make :

the children as the regarded as the variable : x

the adults are the regarded as the variable  : y

<em>5x + 6 y = 1740</em>

<em>x + y = 314</em>

<h3><u>solve this by the method of elimination </u></h3>

5x + 6y = 1740

5(x + y = 314)

= 5x + 5y = 1570

5x + 6y = 1740

5x + 5y = 1570

the 5x is cancelled out

6y - 5y = 1740 - 1570

y = 170

now replace the value of y in the eqaution

5x + 6 (170) = 1740

5x =720

x = 144

hence they were 144 children and 170 adults

there would be a 99% chance of a red marble being pulled out or even a 1% chance.

because of their being five green marbles and six red there is always a chance you could pull out any one of the colors.

but i believe that both of the answers are 1/2

but im not 100% sure

Pavlova-9 [17]

Answer:

  • 30 min
  • 20%

Step-by-step explanation:

The absolute change in game length is ...

  (180 min) -(150 min) = 30 min . . . . change in game length

__

The relative change is expressed as a fraction of the original game length:

  (30 min)/(150 min) × 100% = 20% . . . . relative change in game length
