Draw and describe the plane section that results from the following cut: a cylinder cut parallel to the base.
When a cylinder is cut parallel to its base, the plane section that results is a circle. This circle will have the same radius as the cylinder's base. The center of the circle will be located at the center of the cylinder's base. This type of cut will create a circular cross-section that is parallel to the base of the cylinder.
1. Josh said that the square root of 100 is a perfect square and a perfect cube. Is Josh correct? Explain your reasoning.
Josh is incorrect because 100 is perfect square not a perfect cube.
We have the number 100.
Now, factorising the number 100 as
100 = 2 x 2 x 5 x 5
100= (2 x 5) x ( 2x 5)
100 = 10 x 10
As, 100 can be factorised as 10 x 10 which shows 100 is prefect square of 10.
But 100 is not a perfect cube because for the cube we need pair of three number.
Thus, Josh is incorrect.

The 20 members of the photography club are trying to raise at least $1,400 for
new photography equipment. They have already raised $540.
Let m represent the amount of money each member must raise, on average, to meet
their goal. Write an expression for the total amount of money going to be raised.
b Write an equation that represents the club raising all the money.
с
Solve the equation. What does the solution mean in context of the scenario?
d Write an inequality representing the amount of money each member must raise,
on average, to meet or exceed their goal.
Write an inequality showing the possible average amount of money each club member
needs to raise.
Answer:
i dont know if this helps, im not sure if you are telling me to do all of these things or B, c, d are answer
Step-by-step explanation:
To find the total amount of money that the photography club will raise to meet their goal, we can multiply the average amount of money each member must raise by the number of members in the club:
Average amount of money each member must raise = m
Number of members in the club = 20
Total amount of money to be raised = Average amount of money each member must raise x Number of members in the club
Total amount of money to be raised = m x 20
We know that the club is trying to raise at least $1,400, and they have already raised $540. Therefore, the amount of money they still need to raise is:
Amount of money still needed to reach goal = $1,400 - $540
Amount of money still needed to reach goal = $860
We can set up an equation to represent the total amount of money the club will raise to meet their goal:
Total amount of money to be raised = Amount of money still needed to reach goal
m x 20 = $860
We can solve for "m" by dividing both sides of the equation by 20:
m = $860 / 20
m = $43
Therefore, the total amount of money the club will raise to meet their goal is:
Total amount of money to be raised = Average amount of money each member must raise x Number of members in the club
Total amount of money to be raised = $43 x 20
Total amount of money to be raised = $860
B))) We can set up an equation to represent the total amount of money the club will raise to meet their goal:
Total amount of money to be raised = Amount of money already raised + Amount of money still needed to reach goal
We know that the club has already raised $540 and they need to raise $860 more to reach their goal of $1,400. Therefore, we can substitute these values in the equation:
Total amount of money to be raised = $540 + $860
Total amount of money to be raised = $1,400
So the equation that represents the club raising all the money is:
$1,400 = $540 + $860
C)))) To solve the equation:
$1,400 = $540 + $860
We can simplify the right-hand side of the equation by adding $540 and $860:
$1,400 = $1,400
This equation is true, which means that it is a consistent equation. The solution to this equation is that the club will be able to raise all the money they need to buy the new photography equipment.
In the context of the scenario, the solution means that the club will be able to meet their goal of raising at least $1,400 for new photography equipment. They have already raised $540, and they need to raise $860 more to reach their goal. The equation shows that the total amount of money they will raise is exactly $1,400, which is the amount they need to meet their goal.
D))))) To represent the amount of money each member must raise, on average, to meet or exceed their goal, we can use the following inequality:
Average amount of money each member must raise ≥ Total amount of money still needed to reach goal / Number of members in the club
We know that the total amount of money still needed to reach the goal is $860, and there are 20 members in the club. Therefore, we can substitute these values in the inequality:
Average amount of money each member must raise ≥ $860 / 20
To simplify the right-hand side of the inequality, we can divide $860 by 20:
Average amount of money each member must raise ≥ $43
This inequality shows that each member must raise at least $43, on average, to meet or exceed their goal of raising $1,400.
To show the possible average amount of money each club member needs to raise, we can use the following inequality:
0 < Average amount of money each member must raise ≤ Total amount of money still needed to reach goal / Number of members in the club
This inequality shows that the average amount of money each member must raise is greater than 0 (since each member must contribute something), but it is less than or equal to $43 (which is the minimum amount each member must raise to meet or exceed their goal).

The rocket will hit the ground after 19.09 seconds.
How to calculate projectilea) The height of the rocket can be describe as:
h(t) = -16t² + 210t + 75
where
t = time in seconds
h(t) = height of the rocket in feet
b) To find the time at which the rocket reaches its maximum height, we need to find the vertex of the parabolic function. The vertex is given by the formula:
t = -b/(2a)
where
a = -16
b = 210
Substituting these values, we get:
t = -210/(2(-16)) = 6.5625 seconds
To find the maximum height, we substitute this value of t back into the equation for h(t):
h(6.5625) = -16(6.5625)² + 210(6.5625) + 75 = 690.625 feet
This means that the rocket reaches its maximum height of 690.625 feet after 6.5625 seconds.
c) We need to find the time interval during which the height of the rocket is greater than 721 feet. We set the height function h(t) greater than 721 and solve for t:
-16t² + 210t + 75 > 721
-16t² + 210t - 646 > 0
Solving for t using the quadratic formula, we get:
t < 2.975 or t > 14.038
Therefore, the rocket will be more than 721 feet above ground level between 0 and 2.975 seconds, and between 14.038 and infinity seconds.
d) To find the time at which the rocket hits the ground, we set h(t) equal to 0 and solve for t:
-16t² + 210t + 75 = 0
Solving for t using the quadratic formula, we get:
t = [tex]\frac{-b \± \sqrt{b^{2} - 4ac } }{2a}[/tex]
a = -16, b = 210, c = 75
t = [tex]\frac{-210 \± \sqrt{210^{2} - 4(16)(75) } }{2(-16)}[/tex]
t = [tex]\frac{-210 \± \sqrt{22225} }{-32}[/tex]
t = [tex]\frac{-210 \± 149}{-32}[/tex]
t = 2.53125 or t = 13.53125
Since the rocket was launched from the top of a 75-foot building, it will hit the ground after an additional time of:
t + 2.53125 = 5.09375 seconds or t + 13.53125 = 19.09375 seconds

Divide and state the quotient in simplest form.
The quotient of the two fractions is (x - 5) / (x - 4).
Option D is the correct answer.
We have,
To divide two fractions, we can multiply the first fraction by the reciprocal of the second fraction.
In this case, that means we need to multiply:
(x² - 2x - 15) / (x + 2) x (x + 2) / (x² - x - 12)
Notice that the (x + 2) terms in the numerator and denominator of the first fraction cancel out with the denominator of the second fraction, so we can simplify before multiplying:
(x² - 2x - 15) / 1 x 1 / (x² - x - 12)
Now we can multiply the numerators and the denominators separately:
(x² - 2x - 15) / (x² - x - 12)
To simplify further, we can factor both the numerator and the denominator:
(x - 5)(x + 3) / (x - 4)(x + 3)
Notice that the (x + 3) terms in the numerator and denominator cancel out, leaving:
(x - 5) / (x - 4)

7.003x10^-5 in standard form
Answer:
0.00007003 is the standard form of 7.003x10^-5. In scientific notation, the number is expressed as 7.003 multiplied by 10 raised to the power of negative five. To convert it to standard form, the decimal point has to move to the left by five places since the exponent is negative. The resulting number is a decimal with four zeros before the first nonzero digit. Standard form is a way of representing numbers that does not use exponents and is useful in comparing and performing operations on numbers.
An angle measures 158.2° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
the 2 angles are 169.1° and 10.9°
Step-by-step explanation:
Supplementary angles add to 180
x = first angle
y = second angle = x - 158.2
x + y = 180
x + (x - 158.2) = 180
2x = 180 + 158.2
2x = 338.2
x = 338.2/2 = 169.1
y = 169.1 - 158.2 = 10.9
x + y = 169.1 + 10.9 = 180
Each ice cube measures 1.2in high and 1in in diameter. What is the volume of all 3 ice cubes
[tex]\sf V_{3 Cylinders} =2.8274(in^{3} ).[/tex]
Step-by-step explanation:1. Find a formula for the volume (assuming the shape of the ice cubes is cylindrical).From the provided information about the ice cubes (height and diameter), it's safe to assume that they are cylinder shaped ice cubes. They could be circular cone ice cubes, but the safest assumption is cylinders. Now, to find the volume of a cylinder we use the following formula:
[tex]\sf V_{Cylinder} =\pi r^{2} h[/tex] or [tex]\dfrac{\pi d^{2} h}{4}[/tex].
For the fist equation, "r" stands for radius, and "h" for height.
On the alternate equation, "d" stands for diameter.
2. Calculate.Since we're given the diameter and height, let's use the alternate equation:
[tex]\sf V_{Cylinder} =\dfrac{\pi (1(in))^{2} 1.2(in)}{4}=\dfrac{3}{10} \pi (in^{3} )=0.9425(in^{3} ).[/tex]
3. Calculate the volume of the 3 cubes.This can be done by just multiplying the volume of a single cube ([tex]\dfrac{3}{10} \pi (in^{2} )[/tex]) by 3.
[tex]\sf V_{3 Cylinders} =(3)\dfrac{3}{10} \pi (in^{3} )=\dfrac{9}{10} \pi (in^{3} )=\boxed{\sf 2.8274(in^{3} )}.[/tex]
4. Alternative answer (assuminng the ice cubes have a circular cone shape).Assuming the ice cubes have the shape of a circular cone, this is the process for calculating the volume of all 3 cubes:
[tex]\sf V_{Cone} =\dfrac{1}{3} \pi r^{2} h\\ \\\\ \\ V_{3Cones} =3*\dfrac{1}{3} \pi r^{2} h\\ \\ \\= \pi r^{2} h\\ \\ \\=\pi (\dfrac{1(in)}{2} )^{2} (1.2(in))\\ \\\\ =\dfrac{3}{10} \pi (in^{3} )=\boxed{\sf 0.9425(in^{3} )}[/tex]

t-value?
Based the provided information, the t-value is approximately 1.824.
How do we determine the t-value?We shall work out the t-value by calculating the difference between the sample mean and the population mean, divided by the standard error of the mean.
We shall use the t-test formula to calculate the t-value:
t = (sample mean - population mean) / (sample standard deviation / [tex]\sqrt(sample size)[/tex])
where:
sample mean = 86.3
population mean = 83.5
sample standard deviation = 7.2
sample size = 22
Plugging in these values, we have:
t = (86.3 - 83.5) / (7.2 / √22)
t = 2.8 / (7.2 / 4.69)
t = 2.8 / 1.535

Level E: The repair department of the bicycle shop repairs three things: flat tires, bent handle bars and ripped seats. Today in the repair department, 25% of the bikes had flat tires only, 5% had bent handlebars only, and 10% had ripped seats only. Just 1/12th of the bikes had all three repairs to do: flat tires, bent handlebars and ripped seats. No bikes were completely fixed and there are a total of 101 repairs to be made. How many bikes are in the repair department? How many bikes need two repairs? If less than half of all the bikes have a ripped seat, what is the range of bikes that need both the tires and handlebars repaired without needing to fix the seat?
There are 960 bikes in the repair department and 1.98% of the bikes need two repairs.
The number of bikes with flat tires only is 0.25x, where x is the total number of bikes
The number of bikes with bent handlebars only is 0.05x
The number of bikes with ripped seats only is 0.1x
The number of bikes that need two repairs is 0.01Tx, where T is the percentage of bikes that need two repairs (expressed as a decimal)
The number of bikes that need all three repairs is 0.0833...x
So we have the equation:
0.25x + 0.05x + 0.1x + 0.01Tx + 0.0833...x = 101
Simplifying and solving for x, we get:
x = 960
So there are 960 bikes in the repair department.
To find the number of bikes that need two repairs, we can use the equation:
0.25x + 0.05x + 0.1x + 0.01Tx = 101 - 0.0833...x
Substituting x = 960, we get:
0.25(960) + 0.05(960) + 0.1(960) + 0.01T(960) = 101 - 0.0833...(960)
240 + 48 + 96 + 9.6T = 101 - 80
9.6T = 19
T = 1.98
