Answer:
A)50°F = 10°C
B)75°C = 167°F
C)-40°C = -40°F
Step-by-step explanation:
A) 50°F = 10°C
Formula
(50°F − 32) × 5/9 = 10°C
B) 75°C = 167°F

can someone help me with this
Step-by-step explanation:
so it starts with
182 = 182 × 3 / p
as the price is inversely related to D.
(a)
so, in general
D = 182 × 3/p = 546/p
(b)
D = 546/3.25 = 168 bags
if the price increases to $3.25, then they will sell only 168 bags.
I am sure, the function will not stay linear for every value of p. for example, if they increase the price to $546 per bag, they would still sell 1 bag. but I am certain, they would fall to 0 sold bags much, much earlier than that ...
Suppose g ( x ) = √ x − 3 / x − 11 . what is the domain of g?
The domain of the function g ( x ) = √ x − 3 / x − 11 is R - 11.
What does a function's domain entail?Inputs are assigned outputs by functions. The collection of all potential inputs for a function is its domain. For instance, the domain of f(x)=x2 and g(x)=1/x are all real integers with the exception of x=0.
How do you determine a function's domain?Consider the function y = f(x), which has the independent variable x and the dependent variable y. A value for x is said to be in the domain of a function f if it successfully allows the production of a single value y using another value for x.

Using relations in a right triangle, the secant of angle θ is given by:
D. 5/4.
What are the relations in a right triangle?The relations in a right triangle are given as follows:
The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.Using the Pythagorean Theorem, the hypotenuse of the triangle is given as follows:
h² = 9² + 12²
h = sqrt(9² + 12²)
h = 15.
The secant of an angle is 1 divided by the cosine, hence:
cos(θ) = 12/15 = 4/5.sec(θ) = 5/4.Which means that option D is correct.

A spinning disk with radius 10 cm rotates at 120 rpm.
1. Find the angular speed:
2. Find the linear speed of a point on the edge of the disk:
1) The angular speed is approximately 12.566 radians per second.
2) The linear speed of a point on the edge of the disk is 1.257 meters per second.
What are the angular speed and the linear speed of a spinning disk?
1) Herein we have a disk that spins at constant angular speed (ω), in radians per second, whose magnitude is found dimensional analysis and unit conversions:
ω = 120 rev / min × (2π rad / 1 rev) × (1 min / 60 s)
ω ≈ 12.566 rad / s
The angular speed is approximately 12.566 radians per second.
2) The linear speed (v), in meters per second, on the edge of the disk is described by the following formula:
v = R · ω
Where R is the radius of the spinning disk, in meters.
If we know that R = 0.1 m and ω ≈ 12.566 rad / s, then the linear speed is:
v = (0.1 m) · (12.566 rad / s)
v = 1.257 m / s
The linear speed of a point on the edge of the disk is 1.257 meters per second.

How many kg of peanuts must Heather
add to 4 kg of mixed nuts containing 60%
peanuts to make a mixture with 92%
peanuts?
37.375 kg of peanuts must be added to the 4 kg of mixed nuts to make a mixture containing 92 % of peanuts.
Total mixture of mixed nuts = 4 kg
60 % of them are peanuts.
So, we will calculate the percentage:
Let x be the amount of peanuts.
60 / 100 x = 4 kg
0.6 x = 4 kg
x = 4 kg / 0.6
x = 6.67 kg
Now let the peanuts added be y
So, 92 % of ( 4 kg + y ) should be peanuts.
So, we get the equation as:
0.92 ( 4 ) + 0.92 y = 6.67 + y
3.68 + 0.92 y = 6.67 + y
0.08 y = 2.99
y = 37.375 kg
Therefore, 37.375 kg of peanuts must be added to the 4 kg of mixed nuts to make a mixture containing 92 % of peanuts.

5. A population with mean = 37 and standard deviation = 6 is standardized so that the new mean is 50 and the new standard deviation is 10. A scale of 40 on the first scale is equivalent to what score on the new standardized scale?
Using z-scores, it is found that a scale of 40 on the first scale is equivalent to a score of 55 in the new standardized scale.
What are z-scores?The z-score of a measure X of a distribution with mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is above(in case the score is positive) or below(in case the score is negative) the mean. Looking at the z-score table, the p-value associated with the z-score is found, which represents the percentile of the measure X.For the first scale, the parameters are given as follows:
[tex]X = 40, \mu = 37, \sigma = 6[/tex]
Hence the z-score is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (40 - 37)/6
Z = 0.5.
For the second scale, we want to find X when Z = 0.5, considering the following mean and standard deviation:
[tex]\mu = 50, \sigma = 10[/tex]
Hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
0.5 = (X - 50)/10
X - 50 = 5
X = 55.
A scale of 40 on the first scale is equivalent to a score of 55 in the new standardized scale.

the peremiter of a parallelogram is 56 meters The width of the parallelogram is 4 meters less than its length find the length and the width of the parallelogram
The length of the parallelogram is 16 m and the width of the parallelogram is 12 m.
We are given that the perimeter of a parallelogram is 56 m.
Let the length of the parallelogram be x meter.
So, we get that the width of the parallelogram will be = x - 4 meter.
We also know that:
Perimeter of parallelogram = 2 ( l + b )
Substituting the values in this, we get that:
56 = 2 ( x + x - 4 )
56 = 2 ( 2 x - 4 )
28 = 2 x - 4
2 x - 4 = 28
2 x = 28 + 4
2 x = 32
x = 16
Length = 16 m
Width = 16 - 4 = 12 m
Therefore, the length of the parallelogram is 16 m and the width of the parallelogram is 12 m.

What is the alternate angle property?
The alternate angle theorem states that when two resemblant lines are cut by a transversal, also the performing alternate interior angles or alternate surface angles are harmonious. To prove If two resemblant lines are cut by a transversal, also the alternate innards angles are equal. The Alternate Exterior Angles Theorem states that, when two resemblant lines are cut by a transversal, the performing alternate surface angles are harmonious. Then, the two angles of c and d are outside of the resemblant lines and so these are two exemplifications of alternate surface angles.Equating the alternate angles,
