At a potato chip factory there were 41 machines
working with each machine able to produce 72
chips a minute. If this is enough potato chips to
fill 3 shipping boxes, how many chips are there
per box? How do you know?
Answer:
984 Chips per box
Step-by-step explanation:
41 x 72 = 2952 ÷ 3 (boxes) = 984
Answer:
I got 984 chips per box. (I could be wrong)*
Step-by-step explanation:
My very un-detailed explanation: So you know that there are 41 machines in this potato chip factory and each machine can produce 72 chips every minute. And if this is enough to fill 3 shipping boxes, then the steps to solve this problem is as follows....
1. 41x72=2954 I did this to find the total number of chips that all of the 41 machines make every minute.
2. 2954/3=984 I did this because we know that "2954" chips is the total amount of chips in 3 boxes so to find the amount of chips in each box, we would divide the total number of chips by 3.
is the expression 3(x + 1 1/2) equivalent to 3x + 1 1/2
Answer:
No
Step-by-step explanation:
You only distribute the 3 to the x but not to 1 1/2. In order for the two equations to be the same, you have to distribute 3 to both the x and 1 1/2. Then the answer will look like this : 3x + 4 1/2 or 3x + 9/2
The original expression 3(x + 1 1/2) is not equivalent to 3x + 1 1/2; rather,it simplifies to 3x + 4.5 after distribution and simplification.
Step 1: Distribute the Number Outside the Parentheses:
To determine equivalence, distribute the 3 to both terms inside the parentheses: 3(x) + 3(1 1/2).
Step 2: Simplify Inside the Parentheses:
Multiply 3 by x: 3x.
Multiply 3 by 1 1/2: 3 × 1 + 3 × 1/2
= 3 + 1.5
= 4.5.
Step 3: Combine the Terms:
The distributed expression simplifies to 3x + 4.5.
Step 4: Evaluate the Expression in Question:
The expression provided is 3(x + 1 1/2).
The equivalent expression, as derived, is 3x + 4.5.
Step 5: Compare the Expressions:
The expression 3(x + 1 1/2) simplifies to 3x + 4.5, not 3x + 1 1/2.
Therefore, the original expression 3(x + 1 1/2) is not equivalent to 3x + 1 1/2; rather,it simplifies to 3x + 4.5 after distribution and simplification.

m x H = [tex]\left[\begin{array}{ccc}-25&37.5&-12.5\\\9\end{array}\right][/tex]
Step-by-step explanation:
Step 1; Multiply 5 with this matrix [tex]\left[\begin{array}{ccc}-1&2\\4&8\\\end{array}\right][/tex] and we get a matrix [tex]\left[\begin{array}{ccc}-5&10\\20&40\\\end{array}\right][/tex]
Multiply the fraction [tex]\frac{2}{5}[/tex] with the matrix [tex]\left[\begin{array}{ccc}-1&2\\4&8\\\end{array}\right][/tex] and we get [tex]\left[\begin{array}{ccc}-\frac{2m}{5} &\frac{4m}{5} \\\frac{8m}{5} &\frac{16m}{5} \\\end{array}\right][/tex]
Step2; Now equate corresponding values of the matrices with each other.
-5 = [tex]\frac{-2m}{5}[/tex] and so on. By equating we get the value of m as [tex]\frac{25}{2}[/tex]
Step 3; Add the matrices to get the value of matrix m.
Adding the three matrices on the RHS we get [tex]\left[\begin{array}{ccc}2&9&-9\\\end{array}\right][/tex].
Step 4; Adding the matrices on the LHS we get the resulting matrix as H +
[tex]\left[\begin{array}{ccc}4&6&-8\\\9\end{array}\right][/tex]. Equating the matrices from step 3 and 4 we get the value of H as [tex]\left[\begin{array}{ccc}-2&3&-1\\\9\end{array}\right][/tex]
Step 5; Now to find the value of m x H we need to multiply the value of [tex]\frac{25}{2}[/tex] with the matrix [tex]\left[\begin{array}{ccc}-2&3&-1\\\9\end{array}\right][/tex]
Step 6; Multiplying we get the matrix m x H = [ -25 [tex]\frac{75}{2}[/tex] [tex]\frac{-25}{2}[/tex] ]

What is the slope of the line that contains the points (-2,5) and (6-3)
Answer: m = -1
Step-by-step explanation: In this problem we're asked to find the slope of the line that contains the points (-2,5) and (6,-3).
Using our slope formula, we take the second y minus the first y which in this case is -3 - 5 over our second x minus our first x which in this case is 6 - -2.
-3 - 5 simplifies to -8 and remember that minus a negative can be thought of as plus a positive so 6 - (-2) can be thought of as 6 + (+2) which is 8.
Now we have -8/8. Notice that our slope can be simplified one step further so we have m = -1.
The variable that's used to represent slope is m.
11 - 3x is greater than or equal to 32
Answer:
x ≤ -7
Step-by-step explanation:
Symbolically, we have 11 - 3x ≥ 32
and we can solve this for x as follows:
Add 3x to both sides. We get:
11 - 3x + 3x ≥ 32 + 3x
Then 11 ≥ 32 + 3x
Reversing the order, we get 3x + 32 ≤ 11
Subtracting 32 from both sides, we get:
3x ≤ -21
Finally, dividing both sides by 3 yields:
x ≤ -7

Find the coordinates of the midpoint MM of ST. Then find the distance between points SS and TT. Round the distance to the nearest tenth. S(−2, 4) and T(3, 9)
The midpoint is [tex](\frac{1}{2}, \frac{13}{2})[/tex]
The distance between points S and T is 7.1 units
Solution:
Given points are S(−2, 4) and T(3, 9)
Find the coordinates of the midpoint of ST
The midpoint is given as:
[tex]m(x, y)=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)[/tex]
Here in this sum,
[tex](x_1, y_1) = (-2, 4)\\\\(x_2, y_2) = (3, 9)[/tex]
Substituting the values, we get
[tex]m(x, y)=\left(\frac{-2+3}{2}, \frac{4+9}{2}\right)\\\\m(x, y)=\left(\frac{1}{2}, \frac{13}{2})[/tex]
Thus the midpoint is [tex](\frac{1}{2}, \frac{13}{2})[/tex]
Find the distance between points
The distance is given by formula:
[tex]d=\sqrt{\left(x_{2}-x_{1}\right)^{2}+\left(y_{2}-y_{1}\right)^{2}}[/tex]
Here in this sum,
[tex](x_1, y_1) = (-2, 4)\\\\(x_2, y_2) = (3, 9)[/tex]
Substituting the values, we get
[tex]\begin{aligned}&d=\sqrt{(3-(-2))^{2}+(9-4)^{2}}\\\\&d=\sqrt{5^{2}+5^{2}}\\\\&d=\sqrt{25+25}\\\\&d=\sqrt{50}=7.071 \approx 7.1\end{aligned}[/tex]
Thus the distance between points S and T is 7.1 units
The coordinates of the midpoint [tex]\( M \) are \( (0.5, 6.5) \),[/tex] and the distance between points S and T approximately 7.0 units.
To find the coordinates of the midpoint M of the line segment ST, we use the midpoint formula:
[tex]\[ M = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) \][/tex]
Given the coordinates of [tex]\( S \) and \( T \) are \( S(-2, 4) \) and \( T(3, 9) \)[/tex] respectively, we substitute these values into the formula:
[tex]\[ M = \left( \frac{-2 + 3}{2}, \frac{4 + 9}{2} \right) \][/tex]
[tex]\[ M = \left( \frac{1}{2}, \frac{13}{2} \right) \][/tex]
[tex]\[ M = (0.5, 6.5) \][/tex]
Now, to find the distance between points S and T, we use the distance formula:
[tex]\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \][/tex]
Substituting the coordinates of S and T into the formula:
[tex]\[ d = \sqrt{(3 - (-2))^2 + (9 - 4)^2} \][/tex]
[tex]\[ d \approx 5 \times 1.4 \][/tex]
[tex]\[ d \approx 7 \][/tex]
The coordinates of the midpoint [tex]\( M \) are \( (0.5, 6.5) \),[/tex] and the distance between points S and T is approximately 7.0 units.
If LO = 15x+19 and QN = 10x+2 find PN
Answer:
[tex]PN=64\ units[/tex]
Step-by-step explanation:
The complete question is
Given the quadrilateral is a rectangle, if LO = 15x+19 and QN = 10x+2 find PN
see the attached figure to better understand the problem
we know that
The diagonals of a rectangle are congruent and bisect each other
so
[tex]QN=\frac{1}{2}LO[/tex]
substitute the given values
[tex]10x+2=\frac{1}{2}(15x+19)[/tex]
solve for x
[tex]20x+4=15x+19\\20x-15x=19-4\\5x=15\\x=3[/tex]
Find the length of PN
Remember that
[tex]PN=LO[/tex] ----> diagonals of rectangle are congruent
[tex]LO=15x+19[/tex]
substitute the value of x
[tex]LO=15(3)+19=64\ units[/tex]
therefore
[tex]PN=64\ units[/tex]
if 4cos° + 3sin° =5 ..find sin° and cos°
please anyone
Answer:
x = 36.87 degrees.
Step-by-step explanation:
4 cos x + 3 sin x = 5
Use the Auxiliary angle method:
R sin (α + x) = R sin α cos x + R cos α sin x
Comparing coefficients:
R sin α = 4 and R cos α = 3
R sin α / R cos α = 4/3
So tan α = 4/3
α = 53,13 degrees.
Now R^2(sin^2 α + cos^2 α ) = 3^2 + 4^2 = 25
R^2 = 25
R = 5.
R sin (x + 53.13) = 5
5 sin ( x + 53.13) = 5
sin (x + 53.13) = 1
x + 53.13 = 90
x = 36.87 degrees.

While at the beach Daniel buys lunch for his family from a food stand he purchased one hotdog for $2.50 and three hamburgers if you spent $13 total right and solve an equation to find H the amount of each hamburgers cost
The cost of each hamburger is $ 3.5
Solution:
Given that, Daniel purchased one hotdog for $2.50 and three hamburgers
He spent $ 13 in total
Let "H" be the cost of each hamburger
From given,
one hotdog for $2.50 + three hamburgers each for "H" = $ 13
Thus we get,
[tex]1 \times 2.50 + 3 \times H = 13\\\\2.50 + 3H = 13\\\\\text{Solve the above equation for H}\\\\3H = 13 - 2.50\\\\3H = 10.5\\\\\text{Divide both sides of equation by 3}\\\\H = 3.5[/tex]
Thus cost of each hamburger is $ 3.5
Daniel buys one hotdog for $2.50 and three hamburgers, spending a total of $13. We find the cost of each hamburger by the equation $2.50 + 3H = $13, solve for H, and determine that each hamburger costs $3.50.
Explanation:The problem involves finding the cost of each hamburger that Daniel buys, given that he purchases one hotdog for $2.50 and three hamburgers for a total of $13. To solve this equation, we let H represent the amount each hamburger costs. The total cost of the hotdog and hamburgers together is $13. Therefore, the equation we can write is 1 hotdog + 3 hamburgers = total cost, or $2.50 + 3H = $13. To find H, we subtract the cost of the hotdog from the total cost, which gives us 3H = $13 - $2.50, resulting in 3H = $10.50. Finally, we divide both sides by 3 to find the cost of one hamburger: H = $10.50 / 3, which is H = $3.50. Therefore, each hamburger costs $3.50.

5. If APQR = ASTU.
Find the measure of angle U.
Answer:
∠ U = 117°
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent.
∠ T = ∠ Q = 27°
The sum of the 3 angles in a triangle = 180°, thus
∠ U = 180° - (∠ s + ∠ T) = 180° - (36 + 27)° = 180° - 63° = 117°
