PACKAGING A juice manufacturer is creating new cylindrical packaging. The height of the cylinder is to be 3 inches longer than the radius of the can. The cylinder is to have a volume of 628 cubic inches. Use 3.14 for π.
The radius and height of a cylinder with volume 628 cubic inches are 5 inches and 8 inches respectively.
Volume of a CylinderThe volume of a given cylinder with radius r and height h can be calculated using the formula πr^2h.
In this question, we have the volume of the cylinder given as 628 cubic inches. The height of the cylinder is 3 inches longer than the radius of the can.
Lets assume the radius of the cylinder is equal to r
Substituting the values into the equation;
[tex]v = \pi r^2 h\\628 = \pi r^2 (r + 3)\\628 = 3.14* r^2(r+3)\\r = 5[/tex]
The radius of the equation is 5 inches and the height of the equation is 8 inches.

90 marbles in a bag represent three colors of the US flag there are three times as many red marbles as white marbles there are twice as many blue marbles as white marbles find the number of marbles for each color you select one marble at random from the bag find the probability you picked a red or blue marble
For the given question.
US flag has to be made by total 90 marbles.
Let the number of white marbles be 'x'.
Red marbles are three times the white marble = '3x'.
Blue marbles be twice of white marble = '2x'.
Total marbles = white marble + red marble + blue marble
90 = x + 2x + 3x
6x = 90
x = 15
White marble = 15.
Blue marble 2x = 2×15 = 30.
Red marble 3x = 3×15 = 45.
Probability = favourable outcomes /total outcome
The probability for picking red marble = 45/90 = 1/2.
The probability for picking blue marble = 30/90 = 1/3.
Probability (red or blue) = 1/2 × 1/3
Probability (red or blue) = 1/6
Thus, the probability for picking red or blue marble is 1/6.

Type in the answer to each problem, be sure to include the correct sign with your final answer.
Remember that when adding positive and negative numbers,there are a couple of rules to follow. For example, in this case:
[tex]-8+6[/tex]first, notice that since 8 is greater than 6, then the result will be a negative number.
Then, we substract 6 from 8 to get 2, so the final result would be:
[tex]-8+6=-2[/tex]Next, if we want to add two negative numbers, then we add the numbers and keep the negative sign, for example:
[tex]-2-3[/tex]Notice that 2 plus 3 is 5, and since both 2 and 3 are negative,we have that:
[tex]-2-3=-5[/tex]If we want to substract a negative number from another negative number, like in thiscase:
[tex]-9-(-4)[/tex]just remember that anything that is inside of a parenthesis with a negative sign will change its sign, then, we have the following:
[tex]-9-(-4)=-9+4[/tex]applying the same rules as before we have:
[tex]-9+4=-5[/tex]On the remaining cases, we have the following results:
[tex]\begin{gathered} 5-7=-2 \\ +4+3=7 \end{gathered}[/tex]If the dividend is 415 and the quotient is 83 what is the divisor
the divisor = 5
Explanation:
let the divisor be = x
dividend = number to be divided = 415
quotient = result of the division = 83
dividend/divisor = quotient
415/x = 83
cross multiply:
415 = 83x
Divide both sides by 83:
83x/83 = 415/83
x = 5
Hence, the divisor = 5
Imagine that you are a scientist studying the effects of a new medication on the treatment of patients who get headaches. You separate all the patients into three groups. Group A is given 1 pill with a dose of 20 milligrams of medication once per day. Group B is given 1 pill with a dose of 40 milligrams of the medication once per day. Group C is given 1 pill that looks like the others but is really a sugar pill that contains no medication. The results: 20 percent of the people in Group A claimed that they got fewer headaches, while 80 percent of the people in Group B daimed that they had fewer headaches. Only 1 percent of people in Group C noticed a decrease in their headaches. What might you be able to conclude from this experiment? Explain by identifying the control, the dependent variable, and the independent variable in the experiment.
The control group is the group C, since they take sugar pills.
The dependent variable is the percentage of people that got fewer headaches.
The independent variables is the type of pills they gave to each of the groups.
I'm trying to solve for x by rounding to the nearest hundredth ? can anyone help me please ?
Notice that you are asked to find side "x" in a right angle triangle. and that side "x" is adjecent to the given acute angle of 47 degrees.
Since in this triangle you know the values of the adjacent angle (47 degrees) and that of the hypotenuse (3), you can use the trigonometric function that uses those, that is the "cosine" function of the angle:
Recall that :
[tex]\cos (\theta)=\frac{adjacent}{\text{hypotenuse}}[/tex]so, we can solve for the unknown "adjacent" side (x) multiplying both sides by the hypotenuse value (3), and get:

The line is containing (−4, 9) and (4, 3) which is parallel to the line containing (−8, 1) and (4, y).
y= ?
The value of "y" that satisfies the given conditions is -8.
The first straight line passes through two points. The coordinates of the two points are (−4, 9) and (4, 3). The second straight line passes through two points. The coordinates of the two points are (−8, 1) and (4, y).

Step-by-step explanation:
[tex]xy+7ey=7[/tex]
Differentiate both sides of the equation.
[tex]\frac{d}{dx} (xy+7ey)=\frac{d}{dx}(7e)[/tex]
Differentiate the left side of the equation.
By the Sum Rule, the derivative of [tex]xy+7ey[/tex] with respect to x is [tex]\frac{d}{dx} [xy]+\frac{d}{dx}[7ey][/tex]
Evaluate [tex]\frac{d}{dx} [xy][/tex]

Since [tex]7e[/tex] is constant with respect to [tex]x[/tex], the derivative of [tex]7e[/tex] with respect to [tex]x[/tex] is [tex]0[/tex].
Reform the equation by setting the left side equal to the right side.
[tex]xy'+7ey'+y=0[/tex]
Solve for [tex]y'[/tex].
Subtract [tex]y[/tex] from both sides of the equation.
[tex]xy'+7ey'=-y[/tex]
Factor [tex]y'[/tex] out of [tex]xy'[/tex].
[tex]y'x+7ey'=-y[/tex]
Factor [tex]y'[/tex] out of [tex]7ey'[/tex].
[tex]y'(x)+y'(7e)=-y[/tex]
Factor out [tex]y'[/tex] out of [tex]y'(x)+y'(7e)[/tex]
[tex]y'(x+7e)=-y[/tex]
Divide each term in [tex]y'(x+7e)=-y[/tex] by [tex]x+7e[/tex] and simplify.
[tex]\frac{y'(x+7e)}{x+7e} =\frac{-y}{x+7e}[/tex]

Directions - Graph the following slope intercept equation:y=2/3x-2
Answer
Explanation
The best way to plot graphs, especially straight line graphs, is to use the intercepts. The intercepts are the point(s) that the graph of the function crosses or touches the x and y axis.
The equation is
y = (2/3)x - 2
when x = 0,
y = (2/3)x - 2
y = (2/3)(0) - 2
y = 0 - 2
y = -2
The first point on the graph is (0, -2)
when y = 0,
y = (2/3)x - 2
0 = (2/3)x - 2
(2x/3) = 2
Cross multiply
2x = (2) (3)
2x = 6
Divide both sides by 2
(2x/2) = (6/2)
x = 3
The second point on this graph is (3, 0)
So, the two points are (0, -2) and (3, 0)
We can then easily plot this graph by marking out those two points on the graph and connect the two points for the equation of that line.

The length of the radius of the circle is √61.
Here there are two endpoints of the circle (-7,-4) and (3,8)
To find the length between the two points we have a formula:
length = [tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1} )^{2} }[/tex]
So here we have
([tex]x_{1} , y_{1}[/tex]) = (-7, -4)
([tex]x_{2} , y_{2}[/tex]) = ( 3,8)
Putting the value we have,
[tex]\sqrt{(3 -(-7)^{2} + ( 8-(-4)^{2} }[/tex]
=[tex]\sqrt{10^{2} + 12^{2} }[/tex]
=[tex]\sqrt{100+ 144}[/tex]
=√244
=2√61
The diameter is 2√61
radius = diameter/2
= 2√61/2
= √61

The amount y (inThe cups) of flour is proportional to the number x of eggs in a recipe.The recipe calls for 5 cups of flour for every 3 eggs.Interpret the slope
we have
y -----> cups of flour
x ----> number of eggs
so
slope=y/x
slope=5/3 cups of flour per egg
therefore
slope means 5/3 cups of flour per eggIn this problem the slope is equal to the unit rate
to find out the slope divide the total cups of flour by the total number of eggs
so
we have
5/3=1.67
that means

The monthly cost (in dollars) of a long-distance phone plan is a linear function of the total calling time (in minutes). The monthly cost for 49 minutes of calls is$13.08 and the monthly cost for 86 minutes is $16.41. What is the monthly cost for 72 minutes of calls?Monthly costin dollars)
Answer
The monthly cost for 72 minues of calls = $15.15
Explanation
Let the monthly cost in dollars of the long distance phone plan be represented by y.
Let the total calling time in minutes be represented by x.
We are told that montly cost in dollars of the long distance phone plan, y, is a linear function of the total calling time in minute, x. In mathematical terms and using the equation of a straight line model,
y = a + bx
where
a = fixed amount paid monthly
b = dollar per unit time rate charged on the calls
when x = 49 minutes, y = 13.08 dollars
13.08 = a + 49b ........... equation 1
when x = 86 minutes, y = 16.41 dollars
16.41 = a + 86b ........... equation 2
Combining these simultaneous equations
a + 49b = 13.08 .............. equation 1
a + 86b = 16.41 .............. equation 2
Subtract equation 1 from equation 2
a - a + 86b - 49b = 16.41 - 13.08
37b = 3.33
Divide both sides by 37
(37b/37) = (3.33/37)
b = 0.09 dollars per minute.
We can now solve for a
when b = 0.09
a + 49b = 13.08
a + 49(0.09) = 13.08
a + 4.41 = 13.08
a = 13.08 - 4.41
a = 8.67 dollars
So, the linear function that relates the montly cost in dollars of the long distance phone plan, y, to the total calling time in minute, x is
y = a + bx
a = $8.67 and b = $0.09 per minute
y = 8.67 + 0.09x
When total calling time in minutes, x = 72 minutes, we can now calculate the monthly cost, y.
y = 8.67 + 0.09x
y = 8.67 + 0.09(72)
y = 8.67 + 6.48
y = $15.15
Hope this Helps!!!
