To solve the system of equations, subtract one equation from another to eliminate a variable, then substitute back to find the values of x, y, and z. The correct solution is (x = 0, y = 1, z = 0).
To solve this system of equations, we can use various methods such as substitution, elimination, or matrices. Let's solve it using elimination:
Given the system of equations:
1. ( 4x + 3y + 6z = 3 )
2. ( 5x + 5y + 6z = 5 )
3. ( 6x + 3y + 6z = 3 )
We'll eliminate one variable at a time. Let's start by eliminating ( z ):
From equations 1 and 3, we see that (4x + 3y + 6z) and (6x + 3y + 6z) have the same coefficients for ( z ) but different constants. Subtracting equation 3 from equation 1, we get:
[ (4x + 3y + 6z) - (6x + 3y + 6z) = 3 - 3 ]
[ 4x - 6x = 3 - 3 ]
[ -2x = 0 ]
[ x = 0 ]
Now, substitute ( x = 0 ) into one of the original equations. Let's use equation 1:
[ 4(0) + 3y + 6z = 3 ]
[ 3y + 6z = 3 ]
[ 3y = 3 - 6z ]
[ y = 1 - 2z ]
Now, we have expressions for ( x ) and ( y ). Let's substitute ( x = 0 ) and ( y = 1 - 2z ) into equation 2:
[ 5(0) + 5(1 - 2z) + 6z = 5 ]
[ 5 - 10z + 6z = 5 ]
[ -4z = 0 ]
[ z = 0 ]
So, we found ( x = 0 ), ( y = 1 - 2z = 1 - 2(0) = 1 ), and ( z = 0 ).
Therefore, the solution to the system of equations is ( (x = 0, y = 1, z = 0) ), which corresponds to option c.

1 years since 1975 ? (1 billion = 1,000,000,000)
A) P(t) = 4(1.019)
B) P(t) = 4(1.9)
C) P(t) = 1.194 + 4
D) P(t) = 1.0197 +4
Answer:
[tex]P(t)=4(1.019)^t[/tex]
Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to
[tex]P=a(1+r)^t[/tex]
where
P ---> is the world's population
t ---> is the number of years since 1945
a ---> is the initial population in 1945
r ---> is the percent rate of growth
we have
[tex]r=1.9\%=1.9/100=0.019[/tex]
substitute
[tex]P=a(1+0.019)^t[/tex]
[tex]P=a(1.019)^t[/tex]
Remember that
There were approximately 4 billion people in the world in 1975
That means
Since year 1975 the initial value a=4 billion people
substitute
[tex]P(t)=4(1.019)^t[/tex]

The surface area of a cylinder is given by the formula SA = 2r2 + 2rh. A cylinder has a radius of 10 cm and a surface area of 1,220 cm2. What is the height
Final answer:
To find the height of a cylinder with a known radius and surface area, subtract the area of the bases from the total surface area to get the lateral surface area, and then solve for the height. Using the surface area formula SA = 2πr² + 2πrh, the height is computed to be approximately 9.4 cm.
Explanation:
To calculate the height of a cylinder when you know its surface area and radius, you use the surface area formula for a cylinder, SA = 2πr² + 2πrh, where SA is the surface area, r is the radius, and h is the height of the cylinder. Given that the surface area (SA) is 1,220 cm² and the radius (r) is 10 cm, the formula can be rearranged to solve for h (height). The first step is to calculate the area of the circular bases, which is 2πr², then subtract this value from the total surface area to get the lateral surface area (2πrh), and finally divide by (2πr) to solve for h.
First, calculate the area of the circular bases:
Area of one base = πr² = 3.14159 × 10² cm² = 314.159 cm²
Total area of both bases = 2 × 314.159 cm² = 628.318 cm²
Subtract this from the total surface area to find the lateral surface area:
Lateral surface area = SA - area of bases = 1,220 cm² - 628.318 cm² = 591.682 cm²
Finally, solve for the height:
2πrh = 591.682 cm²
h = 591.682 cm² / (2 × 3.14159 × 10 cm)
h ≈ 9.4 cm
Thus, the height of the cylinder is approximately 9.4 cm.
The height is approximately 9.42 cm.
To find the height of a cylinder when given the radius and the surface area, use the formula for the surface area of a cylinder: [tex]SA = 2\pi r^2+2\pi rh[/tex]. Here, we know the surface area (SA) is 1220 [tex]cm^2[/tex], and the radius (r) is 10 cm.
First, let's write down the formula with the given values:
[tex]1220 = 2\pi (10)^2 + 2\pi (10)h[/tex]
We can simplify the equation step by step:
Calculate [tex]2\pi (10)^2: 2\pi (10)^2=2\pi (100)=200\pi[/tex]Substitute this into the equation: [tex]1220 = 200\pi + 20\pi h[/tex]To isolate 20πh, subtract 200π from both sides: [tex]1220-200\pi =20\pi h[/tex]Approximate the value of [tex]\pi[/tex] (3.142): [tex]200\pi \approx 628.4[/tex]Subtract this value: 1220 - 628.4 [tex]\approx[/tex] 591.6Now, isolate h by dividing both sides by [tex]20\pi : h = \frac{591.6}{20*3.142}\approx9.42[/tex]Therefore, the height of the cylinder is approximately 9.42 cm.

Suppose your friend's parents invest $15,000 in an account paying 6% compounded annually. What will the balance be after 9 years? round to nearest cent
Using the formula for compound interest, the balance of a $15,000 investment at a 6% interest rate compounded annually after 9 years is approximately $25,342.19.
Explanation:To calculate the balance of an investment of $15,000 at 6% interest compounded annually after 9 years, we can use the formula for compound interest, which is:
A = P(1 + r/n)^(nt)
Where:
A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money).r is the annual interest rate (decimal).n is the number of times that interest is compounded per year.t is the time the money is invested for in years.In this case:
P = $15,000r = 6% or 0.06n = 1 (since it's compounded annually)t = 9 yearsPlugging these values into the formula gives us:
A = $15,000(1 + 0.06/1)^(1\*9)
A = $15,000(1 + 0.06)^9
A = $15,000(1.06)^9
A = $15,000\*1.689479
A = $25,342.19 approximately
So, after 9 years, the balance will be $25,342.19, rounding to the nearest cent.

parallel to x = 3 and passes through (6, 1)
Answer:
x = 6
Step-by-step explanation:
x = 3 is the equation of a vertical line parallel to the y- axis.
The equation of a parallel line will therefore be a vertical line.
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (6, 1) with x- coordinate 6, thus
x = 6 ← equation of parallel line
Final answer:
The equation of the line that is parallel to x = 3 and passes through (6, 1) is x = 6.
Explanation:
The question relates to finding the equation of a line that is parallel to another line, specifically the line x = 3, and that also passes through a given point, namely (6, 1). Since the line x = 3 is a vertical line, any line parallel to it will also be vertical and have an equation of the form x = k, where 'k' is a constant.
In this case, the line we are looking for must go through the point (6, 1), which means it will have the same x-coordinate as this point. Therefore, the equation of the line is simply x = 6.
The amount of fuel used by jumbo jets to take off is normally distributed with a mean of 4000 gallons and a standard deviation of 125 gallons. What is the probability that the mean number of gallons of fuel needed to take off for a randomly selected sample of 40 jumbo jets will be less than 3950 gallons?
Answer:
0.6554 is the probability that the mean number of gallons of fuel needed to take off for a randomly selected sample of 40 jumbo jets will be less than 3950 gallons.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 4000 gallons
Standard Deviation, σ = 125 gallons
Sample size, n = 40
We are given that the distribution of amount of fuel is a bell shaped distribution that is a normal distribution.
Formula:
[tex]z_{score} = \displaystyle\frac{x-\mu}{\sigma}[/tex]
Central limit theorem:
As the sample size increases, the distribution of sample mean has a similar popular distribution shape.
P(sample of 40 jumbo jets will be less than 3950 gallons)
P(x < 3950)
[tex]P( x < 3950) = P( z < \displaystyle\frac{3950 - 4000}{125}) = P(z < -0.4)[/tex]
Calculation the value from standard normal z table, we have,
[tex]P(x < 3950) = 0.6554 = 65.54\%[/tex]
0.6554 is the probability that the mean number of gallons of fuel needed to take off for a randomly selected sample of 40 jumbo jets will be less than 3950 gallons.
The probability that the number of gallons of fuel needed to take off for a randomly selected sample of 40 jumbo jets will be less than 3950 gallons is 0.66.
it is given that
Mean μ= 4000 gallons
Standard deviation σ = 125 gallons
Number of trials x = 3950 gallons
What is the formula for a z-score?Z-score = (x-μ)/σ
Z-score = (3950-4000)/125
Z-score = -0.4
So probbaility P(x<3950) = P(z<-0.4)
From the standard normal table,
P(x<3950) = 0.66
Therefore, the probability that the number of gallons of fuel needed to take off for a randomly selected sample of 40 jumbo jets will be less than 3950 gallons is 0.66.

h(x) = x^2 - 1
Over which interval does h have a negative average rate of change?
The function h(x) = x^2 - 1 has a negative average rate of change over the interval from x = -∞ to x = 0, which is where the parabola is decreasing toward its vertex at the origin.
Explanation:The student asked over which interval the function h(x) = x^2 - 1 has a negative average rate of change. The average rate of change is negative when the function is decreasing. In the case of h(x) = x^2 - 1, which is a parabola opening upwards, the function decreases as x moves from the left to the right towards the vertex. Therefore, the interval in which the function has a negative average rate of change is from x = -∞ to x = 0, because this is where the function values are falling. To find the average rate of change between two points x1 and x2, we can use the formula: (h(x2) - h(x1)) / (x2 - x1). If x1 is to the left of the y-axis (x1 < 0) and x2 is the y-axis (x2 = 0), we will get a negative result since h(x2) < h(x1) in that interval, showing a negative average rate of change.
The function h(x) = x^2 - 1 has a negative average rate of change over the interval − 3 ≤ x ≤ 1. This interval includes the vertex of the parabola at x = 0, where the function is decreasing, resulting in a negative rate of change.
The function h(x) = x2 - 1 has different average rates of change depending on the interval we are considering. To find an interval where the average rate of change is negative, we need to look at intervals where the function is decreasing. The function h(x) will be decreasing on any interval that includes the value x = 0 since this is where the vertex of the parabola represented by h(x) is located, and it is a parabola opening upwards.
Analyze intervals around x = 0 to find where the function decreases. Looking at Choice C (−3 ≤ x ≤ 1), we can calculate the average rate of change as:
[(h(1) - h(-3)) / (1 - (-3))] = [(12 - 1) - ((-3)2 - 1)] / (4) = [0 - (9 - 1)] / 4 = -8 / 4 = -2Since the average rate of change is negative (-2), Option C is the interval over which h(x) has a negative average rate of change.

351 rounded to the nearest 10
Answer:
350 is your answer
Step-by-step explanation:
anything lower than five you wouldn't round up you'd round down so basically the 1 is pointless
Rounding 351 to the nearest 10 gives us 350, as per the rule of place value while rounding.
When rounding a number to the nearest 10, we consider the digit in the tens place. If the digit in the unit's place is 5 or greater, we round up; otherwise, we round down.
In the case of 351, the digit in the tens place is 5, and the digit in the units place is 1. Since the digit in the unit's place is less than 5, we round down. Therefore, when rounding 351 to the nearest 10, we get 350.
Rounding 351 to the nearest 10 essentially means approximating it to the nearest multiple of 10. In this case, 351 is closer to 350 than to 360, which is the next multiple of 10.
So, rounding 351 to the nearest 10 gives us 350.

What is the equation for the line of reflection? On a coordinate plane, triangle A B C has points (6, 3.7), (5.4, 2), (1, 3). Triangle A prime B prime C prime has points (3.7, 6), (2, 5.4), (3, 1). x = 3 y = 3 y = x x = 6
Answer:
The answer is y = x
The equation for the line of reflection can be found by using the midpoint formula and the slope formula. The equation for the line of reflection for the given points (6, 3.7) and (3.7, 6) is y = -x + 9.7.
Explanation:The equation for the line of reflection can be found by using the midpoint formula and the slope formula. The midpoint of each corresponding pair of points can be calculated to find the coordinates of the image points. Then, the slope of the original line and the slope of the reflected line can be calculated. Using the midpoint and slope, the equation of the line of reflection can be determined.
For example, to find the equation for the line of reflection for points (6, 3.7) and (3.7, 6), we can calculate the midpoint: ( (6 + 3.7) / 2, (3.7 + 6) / 2 ) = (4.85, 4.85).
Next, we can calculate the slope of the original line using the points (6, 3.7) and (5.4, 2) using the slope formula: (2 - 3.7) / (5.4 - 6) = -1.7 / -0.6 = 2.83.
Finally, we can calculate the slope of the reflected line using the points (4.85, 4.85) and (3.7, 6) using the slope formula: (6 - 4.85) / (3.7 - 4.85) = 1.15 / -1.15 = -1.
So, the equation for the line of reflection is y = -x + b. To find b, we can use the point (4.85, 4.85). Substituting the values into the equation, we get 4.85 = -(4.85) + b, which simplifies to b = 9.7.
Therefore, the equation for the line of reflection is y = -x + 9.7.

Now, to get the volume of scoop which is in the shape of sphere we put formula:
Diameter = [tex]2\frac{7}{8} =\frac{23}{8} \ inches.[/tex]
Thus radius (r) = Diameter ÷ 2 [tex]=\frac{\frac{23}{8}}{2} =\frac{23}{16} \ inches.[/tex]
[tex]Volume = \frac{4}{3} \pi r^3[/tex]
[tex]Volume = \frac{4}{3} \times 3.14\times \frac{23}{16} \times \frac{23}{16} \times \frac{23}{16}[/tex]
[tex]Volume=1.33\times 3.14\times 1.44\times 1.44\times 1.44[/tex]
[tex]Volume=12.47\ inches^3.[/tex]
The volume of one scoop of ice cream = 12.47 inches³.
So, as the volume of scoop of ice cream is more than the volume of cone.
Thus, if placing one scoop of ice cream in the cone and let it melt, the cone will not hold all of the ice cream.
Therefore, no the cone will not hold all of the ice cream.
The ice cream scoop will not fit into the cone due to volume differences.
The ice cream scoop will not fit into the cone. To determine this mathematically, we need to compare the volume of the cone to the volume of the ice cream scoop.
The volume of the cone can be calculated using the formula for the volume of a cone: V = 1/3 × π × r² × h.
Similarly, the volume of the sphere (ice cream scoop) can be calculated using the formula for the volume of a sphere: V = 4/3 × π × r³.
By plugging in the given measurements, we can determine that the volume of the ice cream scoop will be greater than the volume of the cone, indicating that the ice cream scoop will not fit into the cone.

Answer:
8.2
Step-by-step explanation:
Use cosine law:
BC² = 7² + 9² - 2(7)(9)cos(60)
BC² = 67
BC = sqrt (67)
BC = 8.1853
BC = 8.2 (nearest tenth)
If there are 45 guests at the party, predict how many would choose a gift card?
Answer:
Since there is a 50-50 chance of a person at the party choosing a gift card, and since there can only be 1 of 2 outcomes, we can assume that there will either be more people choosing a gift card than not, or there will be more people not choosing a gift card than are. So, that means that there would be 23 people (more or less) choosing a gift card and 22 people (more or less) not choosing a gift card or vice-versa.

Answer:
The costs of the ski packages will be the same if you set them equal to each other. The cost will be the same after 5 hours. The cost will be $35 for both packages.
Step-by-step explanation:
5 + 5x = 20 + 2x Set the equations equal
-5 -5 Subtract 5 from both sides
5x = 15 + 2x
-2x -2x Subtract 2x from both sides
3x = 15 Divide both sides by 3
x = 5
A cup is filled with
100 milliliters of water. Every second, 2
milliliters of water are poured out of the
cup. Which function shows the amount
of water in the cup after t seconds?
Answer:
t=100-2x
Step-by-step explanation:
The amount of water in the cup after t seconds can be represented by the linear function Y = 100 - 2t. This equation is derived from the initial amount of water in the cup and the rate at which water is being poured out.
Explanation:The function that shows the amount of water in the cup after t seconds is a linear function. It can be represented as Y = 100 - 2t. In this equation, Y represents the amount of water left in the cup and t represents time in seconds.
This equation comes from the initial amount of water (100 milliliters) minus the rate of water being poured out of the cup (2 milliliters per second times the number of seconds). For example, after 3 seconds, the amount of water left would be 100 - 2*3 = 94 milliliters.
