Max scored 71 and 65 on his first
two tests in Biology 101. What is the
lowest he must score on the third
test to get an average for the
three tests above 77?
Answers
Answer:
Step-by-step explanation:
If he scored 71 and 65 and needs an average above 77, you took the average needed of 77 and times by 3 since you will have 3 test total. 3*77=231. Take the 231- what you already have which is 136, to get 95. He will need a score of at least 95 to average the 77. 71+65+95=231 231/3= 77
So, x≥95. X is the next test. It would need to be greater than or equal to 95.

The value of the expression is, [tex]\frac{1}{x+6}[/tex].
Step-by-step explanation:
The expression is as follows:
[tex]\frac{5x^{2}+6x+1}{x^{2}+7x+6}\div (5x+1)[/tex]
Solve as follows:
[tex]\frac{5x^{2}+6x+1}{x^{2}+7x+6}\div (5x+1)=\frac{5x^{2}+6x+1}{x^{2}+7x+6}\times \frac{1}{5x+1}[/tex]
[tex]=\frac{5x^{2}+5x+x+1}{x^{2}+6x+x+6}\times\frac{1}{5x+1}\\\\=\frac{(5x+1)(x+1)}{(x+6)(x+1)}\times\frac{1}{5x+1}\\\\=\frac{1}{x+6}[/tex]
Thus, the value of the expression is, [tex]\frac{1}{x+6}[/tex].

Step-by-step explanation:
4z^3 · z^2 · 5z
first, multiply 4z · 1z = 4z and add the exponents 3 + 2 = 5
4z^5 · 5z
multiply 4z · 5z and keep the exponents
20z^5
2m^3p^4 · 4m^2p^3 · 3mp^0
find just the "m" variables: 2m^3 · 4m^2 and same as before multiply then add the exponents = 8m^5
now do the same for the "p" variables: 3p^4 · 2p^3 = 6p^7
and for the "mp" variable: 3mp^0
put it all together and this is the simplest form because we don;t know the values of the variables:
8m^5 · 6p^7 · 3mp^0

A rope is wound round s drum of diameter 21cm is attached to a bucket that is resting at the bottom of a well in depth 9.89 m. Find the number of turns required to bring up the bucket such that the bottom of the bucket is suspended just above the mouth of the well
Answers
Answer:
15
Step-by-step explanation:
Depth of well = No. of turns × length of one turn
Given: Depth of well = 9.89m = 989cm [1m = 100cm]
Let number of turns be x
Length of one turn = 2πr or π×diameter
Now , 989=x×π×21
989=x×(22/7)×21
x=989×7/(22×21)
x=14.98 ≈15 turns
[Number of turn never be in decimals]
Hence number of 15 complete turns of the handle required to bring up the bucket

John has 3 ½ pounds of Skittles. He wants to share them with his friends. He decides to give ¾ pounds of Skittles to each friend. The leftover Skittles he keeps for himself.
Answers
Given :
John has 3 ½ = 7/2 pounds of Skittles.
He decides to give ¾ pounds of Skittles to each friend.
To Find :
How much the leftover Skittles are.
Solution :
Let, his number of bands are x.
So, amount of Skittles left is :
[tex]L= \dfrac{7}{2}-\dfrac{3x}{4}\\\\L = \dfrac{24-3x}{4}[/tex]
Therefore, amount of leftover Skittles are [tex]\dfrac{24-3x}{4}[/tex] pounds if number of friends are x.
Hence, this is the required solution.

To solve for x, we want to use our properties to isolate x.
2x-7=14 [add both sides by 7]
2x=21 [divide both sides by 2]
x=10.5
Now, we know that x=10.5.
