Find the mean:
Day 1: 2
Day 2: 1
Day 3: 4
Day 4: 5
Day 5: 0
Day 6: 7
Mean = [tex] \frac{2 + 1 + 4 + 5 + 0 + 7}{6} = 3.17 [/tex]
This does not exceed a daily mean of 3.5 hours which was set by her mom as a guideline.
Therefore we can conclude that:

The remaining honey in the beehive is 4 gallons and 2 quarts, or 4 quarts and 2 ounces.
we need to convert the given measurements to quarts and ounces and then subtract them from the original 5 gallons.
1 gallon is equal to 4 quarts, and 1 quart is equal to 32 ounces.
4 gallons can be converted to quarts by multiplying by 4:
4 gallons × 4 quarts/gallon = 16 quarts
1 pint is equal to 2 cups, and 1 cup is equal to 8 fluid ounces.
1 pint and 2 ounces can be converted to ounces:
1 pint × 2 cups/pint × 8 ounces/cup = 16 ounces
2 ounces (already in ounces) = 2 ounces
Now, let's add up the converted measurements:
16 quarts + 16 ounces + 2 ounces = 16 quarts and 18 ounces
To find the remaining honey, we subtract the converted measurements from the original 5 gallons:
5 gallons - 16 quarts - 18 ounces = 4 gallons and 2 quarts

A sound measures 42 dB. The intensity of a second sound is four times as great. What is the decibel level of this
second sound?
Answers
Answer:
The decibel level of this second sound is 48.021 decibels.
Step-by-step explanation:
The acoustic intensity ([tex]B_{dB}[/tex]), measured in decibels, is defined by the following formula:
[tex]B_{dB} = 10\cdot \log_{10}\left(\frac{I}{I_{o}} \right)[/tex] (1)
Where:
[tex]I_{o}[/tex] - Reference sound intensity, measured in watts per square meter.
[tex]I[/tex] - Real sound intensity, measured in watts per square meter.
If we know that [tex]B_{dB} = 42\,dB[/tex] and [tex]I_{o} = 10^{-12}\,\frac{W}{m^{2}}[/tex], then the real sound intensity of the first sound is:
[tex]\frac{B_{dB}}{10} = \log_{10}\left(\frac{I}{I_{o}} \right)[/tex]
[tex]\frac{I}{I_{o}} = 10^{\frac{B_{dB}}{10} }[/tex]
[tex]I = I_{o}\cdot 10^{\frac{B_{dB}}{10} }[/tex]
[tex]I = \left(10^{-12}\,\frac{W}{m^{2}} \right)\cdot 10^{\frac{42\,dB}{10} }[/tex]
[tex]I = 1.585\times 10^{-8}\,\frac{W}{m^{2}}[/tex]
The real sound intensity of the second sound is four times greater, that is:
[tex]I' = 6.340\times 10^{-8}\,\frac{W}{m^{2}}[/tex]
If we know that [tex]I_{o} = 10^{-12}\,\frac{W}{m^{2}}[/tex] and [tex]I' = 6.340\times 10^{-8}\,\frac{W}{m^{2}}[/tex], then the acoustic intensity of the second sound is:
[tex]B_{dB} = 10\cdot \log_{10}\left(\frac{I'}{I_{o}} \right)[/tex]
[tex]B_{dB} = 10\cdot \log_{10}\left(\frac{6.340\times 10^{-8}\,\frac{W}{m^{2}} }{10^{-12}\,\frac{W}{m^{2}} } \right)[/tex]
[tex]B_{dB} = 48.021\,dB[/tex]
The decibel level of this second sound is 48.021 decibels.

A golf ball is launched straight up into the air from the ground with an initial velocity of 160 ft/s. The function that models the ball's height is: h(t) = -16t^2 + 160t.
a) Find how long it takes for the golf ball to reached its maximum height.
b) Determine how long the golf ball is in the air before it hits the ground.
c) Determine the maximum height that the golf ball reaches.
Answers
Answer:
a) 5 secb) 10 secc) 400 mStep-by-step explanation:
Given is the quadratic function:
h(t) = -16t^2 + 160tThis gets maximum value at vertex, which is achieved at:
x = -b/2a, of y = ax^2 + bx + cIn our case:
t = -160/2(-16) = 5 secondsMaximum height is at vertex:
h(5) = -16*5^2 + 160*5 = 400 mTime the ball hits the ground, h(t) = 0:
-16t^2 + 160t = 0t^2 - 10t = 0t(t - 10) = 0t = 0 seconds is the starting pointt = 10 seconds is when the ball hits the groundFind the lengths of the missing sides in the pairs of similar triangles

Answer:

Step-by-step explanation:
The inner and outer triangles are similar, thus the ratios of corresponding sides are equal, that is

for Every 3 people at the concert singing along. there are 5 people not singing along. if there are 180 more people not singing along. how many total people are at the concert
Answers
Answer:
288
Step-by-step explanation:
First Divide 180/5=36. So then do 3 times 36=108. (108=People Singing, 180=People not singing). So add 108+180 to get 288.
The total number of people who attend the concert is 288.
Given that, for every 3 people at the concert singing along, there are 5 people not singing along.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Ratio of the number of people singing along at the concert to the number of people not singing along
= 3:5
Now, 3+5=8
The number of more people not singing along = 180
Let the total number of people be x
So, 5/8 × x=180
⇒ x=(180×8)/5
⇒ x=36×8
⇒ x=288
Therefore, the total number of people who attend the concert is 288.

Answer:
x = 43000/9 or 4777.7 (i'm not 100% sure on this, so i apologize if i'm incorrect)
Step-by-step explanation:
The equation you were given was:
amount of solution • rate of concentration = amount of pure acid
By looking at the question, you can conclude that the amount of solution being used is 18%. You need to turn that into a decimal, therefore it'd be 0.18.
You can also conclude that the amount of pure acid being used is 860 milliliters. So, from this, you're able to fill in 2 parts of the equation:
0.18 • x = 860 mL
Now, all there's left to do is solve for x! To do this ,you'll need to rearrange the multiplication problem into a division problem.
860 / 0.18 = x
x = 43000/9 or 4777.7

3) A diver springs up off of a diving board at an initial velocity of 24 ft/sec. The diving board is 30 feet above the water. The function that models the diver's height is: h(t) = -16t^2 + 24t + 30.
a) Find how long it takes for the diver to reach maximum height. Why can't we double this time to find how long the diver is in the air before hitting the water?
b) Determine the maximum height of the diver.
c) How far is the diver from the water after 2 seconds?
Answers
Answer:
a) 3/4 secb) 39 feetc) 14 feetStep-by-step explanation:
Given function:
h(t) = -16t^2 + 24t + 30a) Maximum height is the vertex of the graph. Time needed:
t = -24/2(-16) = 24/32 = 3/4 secIf we double this time then diver will pass the peak point and it doesn't double the height
b) Maximum height is at vertex:
h(3/4) = -16*(3/4)^2 + 24*3/4 + 30 = 39 feetc) Distance from water after 2 seconds:
h(2) = -16*2^2 + 24*2 + 30 = 14 feetFind the unit rate. 5/8 mile in 1/4 hour
Answers
The unit rate in miles per hour is 2.5 mph.
Step-by-step explanation:
1/4 x 4 = 1 hour
5/8 x 4 = miles that would have been covered in one hour
20/8 of a mile would have been covered in one hour
20/8 = 2.5
2.5 miles would have been covered in an hour, with which his speed was 2.5 mph.
A grey squirrel population was introduced in a certain county of Great Britain 30 years ago. Biologists observe that the population doubles every 6 years, and now the population is 100,000. what is the formula
Answers
Answer:
The formula for the gray squirrel population is [tex]n = 3125\cdot 2^{\frac{t}{6} }[/tex].
Step-by-step explanation:
The statement indicates that gray squirrel population increases geometrically, population is doubled every 6 years. That is:
[tex]\frac{n_{t+6}}{n_{t}} = 2[/tex] (1)
If the population after 30 years is 100000, then we construct the following relationship:
[tex]\frac{n_{6}}{n_{o}} \cdot \frac{n_{12}}{n_{6}}\cdot \frac{n_{18}}{n_{12}}\cdot \frac{n_{24}}{n_{18}}\cdot \frac{n_{30}}{n_{24}} = 2^{5}[/tex]
[tex]n_{30} = 2^{5}\cdot n_{o}[/tex]
[tex]n_{o} = \frac{n_{30}}{2^{5}}[/tex] (2)
[tex]n_{o} = \frac{100000}{2^{5}}[/tex]
[tex]n_{o} = 3125[/tex]
A geometric progression for the grey squirrel population is defined by the following formula:
[tex]n = 3125\cdot 2^{\frac{t}{6} }[/tex] (3)
Where:
[tex]t[/tex] - Time, measured in years.
[tex]n[/tex] - Population of gray squirrels.
