Step-by-step explanation:
We know the two sides are equal, so first solve for p.

p=4
Now subsitute p back in for ST

Suzanne Attired makes fashionable garments. During a particular week employees worked 360 hours to produce a batch of 132 garments, of which 52 were seconds (meaning they were flawed). Seconds are sold for $90 each at Attired's Factory Outlet Store. The remaining 80 garments are sold for $200 each. What is the labor productivity ratio of this manufacturing process
Answer:
$57.44 per hour
Step-by-step explanation:
Given that :
Hours worked = 360 hours
Production = 132 batches of garment
Of the 152:
52 were flawed (sold at $90 each)
80 were sold at $200 each
Labor productivity ratio: (output value / input value (hours worked))
Output value = [(52*$90) + (80*$200)]
Output value = $20,680
Labor productivity ratio = $20,680 / 360 hours
Labor productivity ratio = $57.44 per hour

determine the range of the following graph
Answer:
Range: [-6, 8]
Step-by-step explanation:
Range is the set of y-values that are outputted by function f(x).
From the graph we see that our y-values span from -6 to 8. Since both are closed dot, they are included in the range:
[-6, 8] or -6 ≤ y ≤ 8

Find the equation of the perpendicular bisector of AB when A(-7,2) and B(3,4)
Given:
Two points are A(-7,2) and B(3,4).
To find:
The perpendicular bisector of AB.
Solution:
Slope formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Slope of AB is
[tex]m_1=\dfrac{4-2}{3-(-7)}[/tex]
[tex]m_1=\dfrac{2}{3+7}[/tex]
[tex]m_1=\dfrac{2}{10}[/tex]
[tex]m_1=\dfrac{1}{5}[/tex]
Procut of slopes of perpendicular line is -1.
So, slope of perpendicular bisect is opposite of reciprocal of [tex]\dfrac{1}{5}[/tex].
[tex]m_2=-5[/tex]
Midpoint of AB is
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-7+3}{2},\dfrac{2+4}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{-4}{2},\dfrac{6}{2}\right)[/tex]
[tex]Midpoint=\left(-2,3\right)[/tex]
Slope of perpendicular bisector is -5 and it passes through (-2,3), so the equation of perpendicular bisector is
[tex]y-y_1=m(x-x_1)[/tex]
where, m is slope.
[tex]y-3=-5(x-(-2))[/tex]
[tex]y-3=-5(x+2)[/tex]
[tex]y-3=-5x-10[/tex]
Add 3 on both sides.
[tex]y=-5x-10+3[/tex]
[tex]y=-5x-7[/tex]
Therefore, the equation of perpendicular bisector is [tex]y=-5x-7[/tex].

Given 45-45-90 triangle with hypotenuse of 3cm solve for the other sides.
Answer:
[tex]\sqrt{\frac{9}{2} }[/tex]
Step-by-step explanation:
Given dimensions:
The right angle system is a 45 - 45 - 90
Hypotenuse = 3cm
Unknown:
Adjacent and opposite sides = ?
Solution:
In this triangle, the adjacent and opposite sides are equal to one another. So,
Let adjacent = y
opposite = y
For right angle triangles as this, using the Pythagoras theorem,
hypotenuse² = adjacent² + opposite²
Insert the parameters and solve;
3² = y² + y²
2y² = 9
y² = [tex]\frac{9}{2}[/tex]
y = [tex]\sqrt{\frac{9}{2} }[/tex]

Over the course of a week, an airline has 42 flights between New York and Los Angeles. Of these flights, 28 are considered
to be "on-time."
If you chose a particular flight at random, what is the probability that it would not be on-time? Express your answer as a
fraction.
Provide your answer below:
Answer:
The probability that a particularly randomly chosen flight will not be on time is 1/3
Step-by-step explanation:
The number of flights available between New York and Los Angelis = 42 flights
The number of flights that are considered to be on time = 28 flights
The probability that a particularly randomly chosen flight will not be on time = 1 - The probability that the flight will be on time
The probability that the flight will be on time = (The number of flights considered to be on time)/(The total number of flights available)
The probability that the flight will be on time = 28/42 = 2/3
∴ The probability that a particularly randomly chosen flight will not be on time = 1 - 2/3 = 1/3
The probability that a particularly randomly chosen flight will not be on time = 1/3.
Identify the value for the variable
Answer:
-12, 4
Step-by-step explanation:
7^-9 x 7^-3 = 7^-12
When you multiply exponents with the same base, you add them.
11^-4/11^-8 = 11^4
When you subtract exponents with the same base, you subtract the exponent in the numerator by the exponent in the denominator.
Which of the following steps could be used to solve the equation 93 = x + 58?
Answer:
x=35
Step-by-step explanation:
93=x+58
-58 -58
35=x
x=35
Simply subtract 58 on both sides so it crosses out, isolating x.
Also x would be 35 in case you need that.
