Answer: We can only determine the cost for each burger if we know the total cost of all the ground beef. Let's assume that the ground beef costs $C in total.
If Coach Miller is using all the ground beef to grill 17 burgers, then the cost of each burger is:
Cost per burger = Total cost of ground beef / Number of burgers
We know that the total cost of ground beef is $C, and we know that there are 17 burgers. Substituting these values into the formula gives:
Cost per burger = C / 17
Therefore, the cost for each burger is C/17. We cannot determine the numerical value of C or the cost per burger without additional information.

Answer: Table 3
Step-by-step explanation:
exponential relationship means the y value is increasing/decreasing exponentially
In table 1: the value of y is NOT increasing/decreasing exponentially as 2 is being added continuously (linear), so not table 1
In table 2: the value of y is NOT increasing/decreasing exponentially as 4 is being subtracted continuously (linear), so not table 2
In table 3: the value of y IS increasing exponentially as the y variable is multiplied by 2, so table 3
In table 4: the value of y is NOT increasing exponentially as the y variable is only being increased by 5 constantly (linear), so not 4

Use the figure to find the length of BC.
Answer:
B) 2
Step-by-step explanation:
First, we need to find BD:
by the Pythagorean theorem, (sqrt13)^2 + (sqrt23)^2 = BD^2
we can simplify this to 13+23=BD^2, which means BD^2 = 36, and BD is 6.
Therefore to find BC, we can use the Pythagorean theorem again and create the formula:
(4sqrt2)^2 + BC^2 = 6^2
This simplifies to 32 + BC^2 = 36, which means that BC^2 = 4, and BC = 2.
The population of California is approximately 3. 8 × 107, and the population of Nebraska is approximately 1. 9 × 106. Which state has the larger population, and by how many times is its population larger than the other state’s?
California has the larger population, and it is approximately 20 times larger than Nebraska's population.
The population of California is 3.8 million, while the population of Nebraska is 1.9 million. To find the difference between the two populations, we can calculate 3.8 million minus 1.9 million, which equals 1.9 million. To find the ratio, we can divide the population of California by the population of Nebraska, which is 3.8 million divided by 1.9 million, which equals 2. Thus, California has a population that is 20 times larger than the population of Nebraska.

The perimeter of the quadrilateral GHJK is 24(1+√2) which can be by using the radius of the circle, 6cm.
What is perimeter?Perimeter is the total length of the outside boundary of any two-dimensional shape. Perimeter is calculated by adding up the length of each side of a shape.
In order to calculate the perimeter of the quadrilateral, we need to first find the length of the sides.
We can do this by using the radius of the circle, r.
The side GH is equal to r+r=2r.
The side HK is equal to (r+r)√2=2r√2.
The side JK is equal to (r+r)√2=2r√2.
And the side GJ is equal to 2r.

a concave mirror has a focal length of 16 cm . at what object distance will the magnification be -2.0?
The object distance is 0, which implies that the object is at the focus of the concave mirror.
For a concave mirror, the magnification is given by the formula:
m = -di/do
where m is the magnification, di is the image distance, and do is the object distance. Since we are given that the magnification is -2.0, we can write:
-2.0 = -di/do
Simplifying this expression, we get:
di = 2do
We can also use the mirror formula for a concave mirror:
1/f = 1/do + 1/di
where f is the focal length of the mirror. Substituting di = 2do and f = -16 cm (since the mirror is concave), we get:
1/-16 = 1/do + 1/(2do)
Multiplying both sides by -16do, we get:
do - 2f = -32
Substituting f = -16 cm, we get:
do - (-32) = -32 + 32
do = 0
This means that the object distance is 0, which implies that the object is at the focus of the concave mirror. This is a valid result, since a concave mirror can form a real, inverted image for an object placed at a distance equal to its focal length. In this case, the magnification would be -1, not -2. So, it is not possible to have a magnification of -2 for an object distance in front of a concave mirror with a focal length of 16 cm.

Edna watches TV for 2 to 7 hours every week, depending on how busy she is. If you look at a
log of the amount of time she spends watching TV weekly, what kind of sequence will you
see?
We would see a logarithmic sequence of values if we plotted the amount of time Edna spends watching TV weekly on a logarithmic scale.
If we plot the amount of time Edna spends watching TV on a logarithmic scale, we would see a continuous sequence of values that increase as her viewing time increases. Specifically, the sequence would be a logarithmic scale of the number of hours she watches TV per week.
On a logarithmic scale, each increment corresponds to a multiplication by a constant value. For example, if we use a logarithmic scale base 10, then each increment of 1 corresponds to a multiplication by 10. So, if we plot Edna's TV watching time on a logarithmic scale, we would see a sequence of values that increase by a factor of 10 as her TV watching time increases by an order of magnitude.
For example, if Edna watches 2 hours of TV per week, the logarithmic value would be log(2) = 0.3. If she watches 7 hours per week, the logarithmic value would be log(7) = 0.85. If she watches 20 hours per week, the logarithmic value would be log(20) = 1.3. As her viewing time increases, the logarithmic values would continue to increase in a continuous sequence.
Therefore, if we plotted the amount of time Edna watches TV each week on a logarithmic scale, we would see a logarithmic sequence of numbers.

just before a referendum on a school budget, a local newspaper polls 377 voters to predict whether the budget will pass. suppose the budget has the support of 54% of the voters. what is the probability that the newspapers sample will lead it to predict defeat?
The probability that the newspapers sample will lead it to predict defeat is 92.36%.
To solve this problem, we need to use the binomial distribution formula.
Let's define the following:
X: number of voters in the sample who do not support the budget (i.e., the sample leads to a prediction of defeat).
n: sample size, which is 377.
p: proportion of voters who support the budget, which is 0.54 (since 54% support it, 46% do not support it).
The probability of the sample leading to a prediction of defeat is:
P(X = k) = (n choose a) * pᵃ * (1-p)ⁿ⁻ᵃ
where (n choose a) = n! / (a! * (n-a)!) is the binomial coefficient.
We want to find P(X >= 189), which means that at least 189 voters in the sample do not support the budget.
P(X >= 189) = 1 - P(X < 189)
To calculate P(X < 189), we can use a normal approximation to the binomial distribution, since n is large and p is not too close to 0 or 1.
The mean of the binomial distribution is mu = n * p = 377 * 0.54 = 203.58
The standard deviation is sigma = √(n * p * (1-p)) = √(377 * 0.54 * 0.46) = 10.20
We can standardize X using the z-score formula:
z = (X - mu) / sigma
P(X < 189) = P(z < (189 - 203.58) / 10.20) = P(z < -1.43)
Using a standard normal table or calculator, we can find that P(z < -1.43) = 0.0764.
Therefore, P(X >= 189) = 1 - P(X < 189) = 1 - 0.0764 = 0.9236.
So the probability that the newspaper's sample will lead it to predict defeat is approximately 0.9236, or 92.36%.

the agent earns a 6% commission on the first $300,000 of the sales price and 3% of that portion of the sales price that exceeds $300,000. the commission is $21,150. what is the sales price?
As per the given commission, the sales price of the property is $405,000.
To do this, we need to break down the commission earned by the agent into two parts: the commission earned on the first $300,000 and the commission earned on the remaining amount. The commission earned on the first $300,000 can be calculated as:
Commission on first $300,000 = 6% of $300,000
Commission on first $300,000 = 0.06 x $300,000
Commission on first $300,000 = $18,000
So, the remaining commission earned by the agent on the amount that exceeds $300,000 is:
Total commission - Commission on first $300,000 = $21,150 - $18,000
Total commission - Commission on first $300,000 = $3,150
Now, we know that the commission earned on the remaining amount is 3% of the sales price that exceeds $300,000. Let's assume the sales price of the property is x. Then we can write the following equation:
3% of (x - $300,000) = $3,150
We can simplify this equation as follows:
0.03(x - $300,000) = $3,150
x - $300,000 = $3,150 / 0.03
x - $300,000 = $105,000
x = $300,000 + $105,000
x = $405,000

The formula for the volume of a cylinder is V= π r2 h. What is the radius for a cylinder that has a volume of 160π m3 and a height of 8m? express your answer in simplest radical form and as a decimal rounded to the nearest tenth
The cylinder has a radius of 2 times the square root of 5 meters, or roughly 4.5 meters rounded to the nearest tenth.
The formula for the volume of a cylinder is:
V = πr²h
where V is the volume, r is the radius, and h is the height.
In this case, we have:
V = 160π m³
h = 8 m
Substituting these values into the formula, we get:
160π = πr²(8)
Simplifying the equation by canceling out π on both sides, we get:
160 = 8r²
Dividing both sides by 8, we get:
20 = r²
Taking the square root of both sides, we get:
r = √20
Simplifying the radical by factoring out 4, we get:
r = 2√5
To express the radius as a decimal rounded to the nearest tenth, we can use a calculator to get:
r ≈ 4.5
Therefore, the radius of the cylinder is 2√5 meters or approximately 4.5 meters to the nearest tenth.

The inner surface area of the vessel, given the diameter of the hemisphere and the total height, is 133π cm².
How to find the inner surface area ?To find the inner surface area of the vessel, we will consider the hemisphere and the cylinder separately, and then sum their inner surface areas.
Hemisphere:
The diameter of the hemisphere is 14 cm, so its radius (r1) is half of that:
r1 = 14 cm / 2 = 7 cm
Inner surface area (hemisphere) = 2 * π * r1² / 2 = π * r1² = π * (7 cm)² = 49π cm²
The radius of the cylinder is the same as the hemisphere's (r2 = r1 = 7 cm). The height (h) of the cylinder can be found by subtracting the height of the hemisphere from the total height of the vessel:
h = total height - hemisphere height = 13 cm - 7 cm = 6 cm
Inner surface area (cylinder) = 2 x π x r2 x h = 2 x π x (7 cm) x (6 cm) = 84π cm²
Total inner surface area = inner surface area (hemisphere) + inner surface area (cylinder)
Total inner surface area = 49π cm² + 84π cm² = 133π cm²

A car's wheels are 20 in. in diameter. How far (in mi) will the car travel if its wheels revolve 10,000 times without slipping. ______mi
If the car's wheels revolve 10,000 times without slipping, the car will travel approximately 9.92 miles.
How far (in mi) will the car travel if its wheels revolve 10,000 times without slipping?The circumference of a circle (which is the distance around it) is given by the formula:
C = πd, where d is the diameter of the circle.
In this case, the diameter of the car's wheels is 20 in., so the circumference of each wheel is:
C = πd
C= π(20 in.) =
C = 20π in.
If the car's wheels revolve 10,000 times without slipping, then the total distance the car travels is:
distance = number of revolutions × circumference
distance = 10,000 × (20π in.)
To convert this distance to miles, we need to divide by the number of inches in a mile, which is 63,360 in.
distance = (10,000 × 20π in.) / 63,360 in./mi
