Pleaseee help me this is gonna be due in a little and I need help bad it’s pretty algebra
Anarel [89]

Answer:

a.) .375 inches per day

b.) no

c.) 48 days

Step-by-step explanation:

If 8 days produces 3 inches of ice, I divided the 3 inches by the 8 days to see how much it grew per day. I got<u> .375 inches per day</u>.

Knowing how much it grew each day, I used .375 inches per day and multiplied it by 21 (3 weeks). So <u>no, it only grew 7.875 inches over the 21 days</u>.

You can double check it by dividing 10 inches / .375 inches per day and saw it would take over 26 days to reach 10 inches.

I took 1.5 feet and converted it to 18 inches. 18 inches divided by .375 inches per day equals <u>48 days.</u>

I hope this helps you! :)

How many distinct seven-digit phone numbers can you create from the numbers 4, 4, 5, 6, 7, 7, 7? (e.g. 445-6777 is one example)?
iris [78.8K]
You have 7 numbers, two numbers 4 , one 5, one 6 and three numbers 7.

From these 7 numbers you can create 7!=1\cdot2\cdot3\cdot4\cdot5\cdot6\cdot7=5040 phone numbers, but they are not all different.

If you have two numbers 4, then you have to divide obtained number by 2! (the number of all possible permutations of two numbers 4) and since you have three numbers 7 you should divide the obtained number by 3! (<span>the number of all possible <span>permutations of three numbers 7</span>). Then</span><span /><span>
</span><span>
</span><span>\dfrac{5040}{2!\cdot 3!}= \dfrac{5040}{1\cdot2\cdot1\cdot2\cdot3}=420.</span>

Answer: You can create 420 different phone numbers.<span />

Using the quadratic formula to solve x2 = 5 - X, what are the values of X?
sdas [7]

Answer:

The answer is

<h3>x =  \frac{ - 1 +  \sqrt{21} }{2}  \:  \:  \: or \:  \:  \: x =  \frac{ - 1 -  \sqrt{21} }{2}</h3>

Step-by-step explanation:

x² + x - 5 = 0

Using the quadratic formula

That's

<h3>x =  \frac{  - b\pm \sqrt{ {b}^{2} - 4ac } }{2a}</h3>

From the question

a = 1 , b = 1 , c = - 5

Substitute the values into the above formula and solve

We have

<h3>x =  \frac{ - 1\pm \sqrt{ {1}^{2} - 4(1)( - 5) } }{2(1)}  \\ x =  \frac{ - 1\pm \sqrt{1  + 20 } }{2}  \\ x =   \frac{ - 1\pm \sqrt{21} }{2}</h3>

We have the final answer as

<h3>x =  \frac{ - 1 +  \sqrt{21} }{2}  \:  \:  \: or \:  \:  \: x =  \frac{ - 1 -  \sqrt{21} }{2}</h3>

Hope this helps you
