You are a camp counselor and have 2/3 pound of fishing bait. If you give each
camper 1/6 pound, how many campers receive bait? Before you model and
solve this problem, estimate your answer.
Write a division expression that would represent the situation above.
Answers
C = amount of campers
so, if we give each campler 1/6 lb evenly, whatever that sum will just add up to 2/3 lb.
If we have "C" campers, the product of 1/6 * C gives use that sum, so we can say that
\(\cfrac{1}{6}C~~ =~~\cfrac{2}{3}\implies C = \cfrac{~~ \frac{2}{3}~~}{\frac{1}{6}}\implies C = \cfrac{2}{3}\div \cfrac{1}{6}\implies C = \cfrac{2}{\underset{1}{~~\begin{matrix} 3 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}}\cdot \cfrac{\stackrel{2}{~~\begin{matrix} 6 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~}}{1}\implies C = 4\)

The equivalent expression of log4 ( 1/4x²) is log4(1/4) + log4(x²) ( option D)
What are laws of logarithm?The logarithm is the inverse function to exponentiation. For example log2 (8) = 3 and 2³ = 8
The following are math logarithm rules:
loga (MN) = loga M + loga N.
loga (M/N) = loga M - loga N.
IogaMn = n Ioga M.
For example Log5 (5²) = Log5 (5) + Log5 (5)
= 1+1 = 2
this means Log5 ( 5²) = log5 ( 25) = 2
Therefore if loga (MN) = loga M + loga N.,
we can say that,
log4( 1/4x²) can also be written as ;
log4 (1/4) + log4 (x²) .
therefore the equivalent expressions for
log4 ( 1/4x²) is log4 (1/4) + log4 (x²) .

Answers
The correct answer is C. It is the graph of f(x) translated 11 units to the left.
The correct answer is:
C. It is the graph of f(x) translated 11 units to the left.
When we have a function of the form g(x) = f(x - a), it represents a horizontal translation of the graph of f(x) by 'a' units to the right if 'a' is positive and to the left if 'a' is negative.
In this case, g(x) = f(x - 11), which means that the graph of f(x) is being translated 11 units to the right. However, the answer options do not include this specific transformation. The closest option is option C, which states that the graph of g(x) is translated 11 units to the left.
The graph of f(x) = x is a straight line passing through the origin with a slope of 1. If we apply the transformation g(x) = f(x - 11), it means that we are shifting the graph of f(x) 11 units to the right. This results in a new function g(x) that has the same shape and slope as f(x), but is shifted to the right by 11 units.
Therefore, the correct answer is C. It is the graph of f(x) translated 11 units to the left.

Answers
Solution:
Calculating the polled variance
\($ S_p^2 = \frac{(n_1-1)S_1^2+(n_2-1)S_2^2}{n_1+n_2-2}$\)
= \($ \frac{(28-1)\times 119^2+(28-1)\times 125^2}{28+28-2}$\)
= 14893
Now we calculate the estimated standard error
\($ S_{M1-M2} =\sqrt {\frac{S_p^2}{n_1}+\frac{S_p^2}{n_2}}$\)
\($=\sqrt{\frac{14893}{28}+\frac{14893}{28}} = 32.61$\)
Thus , the 99 percent confidence interval is
= \($(M_1-M_2) \pm t_{54.001}\times S_{M_1-M_2}$\)
= 351 - 305 ± 2.660 x 32.6
= (46) ± 86.74
= (-40.74, 132.74)
Now the null hypothesis is :
\($H_0 : u_1-u_2 = 0$\)
Against the alternative hypothesis
\($H_0 : u_1-u_2 > 0$\)
Computing the statistics ,
\($t = \frac{(M_1-M_2)-(u_1-u_2)}{S_{M_1-M_2}}$\)

Chris has just sold a home valued at $85,000. Her
normal commission for the homes that she sells
is 8%. Determine the amount that Chris will make
on the sale of the $85,000 home.
Answers
Answer:
Amount of Chris' commission = $6800
Step-by-step explanation:
Given that:
Value of the house sold by Chris = $85,000
Percent of Chris' commission = 8%
Amount of Chris' commission = 8% of 85000
Amount of commission = \(\frac{8}{100}*85000\)
Commission = 0.08 * 85000
Commission = $6800
Hence,
Amount of Chris' commission = $6800
With a certain medical insurance policy, the customer must first pay an annual $250deductible, and then the policy covers 70% of the cost of x-rays. The first insurance claims for a specific year submitted by a person are for two x-rays. The first x-ray cost $700, and the second x-ray cost $950. How much, in total, will he need to pay for these x-rays?
I got $345, but it's wrong.
Answers
Answer:
$495 (745 if you include the $250 deductible)
Step-by-step explanation:
70% of 700 is 490
700 - 490 = 210
70% of 950 is 665
950 - 665 = 285
210 + 285 = $495
Answer:
495
Step-by-step explanation:
70% of 700= 490
700 - 490= 210
70% of 950= 665
950 - 665= 285
Add them together
210 + 285= 495
The reason you might have gotten 345 is because you subtracted 495 with 250 but 250 is how much he has to pay for the medical insurance, not how much he also get off
from a point 1.75 m above the ground and 10 m away from a tower the angle of elevation of a top of a tower is 60 degree calculate the height of the tower
Answers
Answer:

Step-by-step explanation:
Let’s call the height of the tower H. The distance from the point to the base of the tower is 10 m. The angle of elevation from the point to the top of the tower is 60 degrees.
Using trigonometry, we can calculate that:
tan (60) = H / 10
H = 10 * tan (60)
H = 10 * √3
H = 17.32 m
Therefore, the height of the tower is 17.32 meters.

Ms C's car uses 20 gallons of gas to travel 400 miles. If she currently has 3 gallons of gas in her car, how much gas is needed to travel 250 miles? Round your answer to the nearest tenth.
Answers
Using the concept of proportion, amount of gas needed to travel 250 miles is 9.5 gallons.
Given that,
Ms C's car uses 20 gallons of gas to travel 400 miles.
We have to first find the number of gallons of gas to be used to travel 250 miles.
Amount of gas used to travel 400 miles = 20 gallons
Using the concept of proportion,
Amount of gas used to travel 1 mile = 20 / 400
= 0.05 gallon
Amount of gas used to travel 250 miles = 0.05 × 250
= 12.5 gallons
There is already 3 gallons of gas in her car.
Amount of gas needed = 12.5 - 3 = 9.5 gallons

An equation of the line that goes through the point (-1, -3) and (3, 5) is y = 2x - 1.
An equation of the line in slope-intercept form that is perpendicular to the equation for obstacle 1 is y = -x/2 + 3.
How to determine an equation of this line?In Mathematics, the point-slope form of a straight line can be calculated by using the following mathematical expression:
y - y₁ = m(x - x₁) or \(y - y_1 = \frac{(y_2- y_1)}{(x_2 - x_1)}(x - x_1)\)
Where:
m represent the slope.x and y represent the points.At data point (-1, -3), a linear equation in slope-intercept form for this line can be calculated by using the point-slope form as follows:
\(y - y_1 = \frac{(y_2- y_1)}{(x_2 - x_1)}(x - x_1)\\\\y - (-3) = \frac{(5- (-3))}{(3-(-1))}(x -(-1))\\\\y +3 = \frac{(5+3)}{(3+1)}(x +1)\)
y + 3 = 2(x + 1)
y = 2x + 2 - 3
y = 2x - 1
In Mathematics, a condition that must be met for two lines to be perpendicular is given by:
m₁ × m₂ = -1
2 × m₂ = -1
m₂ = -1/2.
At point (-4, 5), an equation of the line can be calculated by using the point-slope form as follows:

What is compounded interest?Compounded interest refers to the interest system that charges interest on both principal and accumulated interest.
The period of compounding in a year determines the worth of the future value.
The future value can be ascertained using an online finance calculator as follows:
Interest periods: = 4 times yearly (Quarterly)
Principal = $5,000
Annual interest rate = 9%
Number of years: 18
N (# of periods) = 72 quarters (18 years x 4)
I/Y (Interest per year) = 9%
PV (Present Value) = $5,000
PMT (Periodic Payment) = $0

Future Value (FV) = $24,815.83
Total Interest = $19,815.83
Interest periods: = Annually
N (# of periods) = 18 years
I/Y (Interest per year) = 9%
PV (Present Value) = $5,000
PMT (Periodic Payment) = $0

The average rate of growth for human hair is about 0.3 millimeters per day. How many days will it take a hair that is 12 millimeters long to grow to be 16.5 millimeters?
Answers
It will take 15 days for the hair to grow from 12mm to 16.5mm
What do you mean by average rate?By "average rate" in this context, we mean the typical or usual amount of hair growth per unit of time, which is often measured in millimeters per day. This rate can vary slightly depending on factors such as age, gender, genetics, diet, and overall health.
Let's first find out how much the hair needs to grow by subtracting its initial length (12mm) from its target length (16.5mm):
16.5mm - 12mm = 4.5mm
Now we can divide this growth by the average rate of hair growth to find the number of days it will take to grow this much:
4.5mm ÷ 0.3mm/day = 15 days
Therefore, it will take 15 days for the hair to grow from 12mm to 16.5mm.

What is the slope of the line perpendicular to the line 14x-7y=6
Answers
Answer:
\((-1/2)\).
Step-by-step explanation:
In a cartesian plane, if the equation of a line is in the slope-intercept form \(y = m\, x + b\), then \(m\) would be the slope of that line.
Rewrite the equation of the given line to obtain the slope-intercept equation for this line:
\(\displaystyle 2\, x - y = \frac{6}{7}\).
\(\displaystyle -y = -2\, x + \frac{6}{7}\).
\(\displaystyle y = 2\, x - \frac{6}{7}\).
In other words, the slope of the given line is \(2\).
Let \(m_{1}\) denote the slope of the given line, and let \(m_{2}\) denote the slope of the line perpendicular to the given line.
If two lines in a cartesian plane are perpendicular to one another, the product of their slopes would be \((-1)\). In other words, \(m_{1} \cdot m_{2} = -1\). Rearrange to obtain an expression for the slope of the line perpendicular to the given line:
\(\displaystyle m_{2} = -\frac{1}{m_{1}}\).
The slope of the given line has been found: \(m_{1} = 2\). Hence, the slope of the line perpendicular to this given line would be:
\(\begin{aligned}m_{2} &= -\frac{1}{m_{1}} \\ &= -\frac{1}{2}\end{aligned}\).
