Apply the properties of operations to multiply the expression
Answers
The properties of operations to multiply the expression are commutative property, associative property, and distributive property.
Let us understand the properties of operations to multiplication:
The foundation of arithmetic is the Properties of Operations; we use them when performing computations and recalling basic facts.
There are basically three properties of operations to multiplication which are:
Commutative Property: The commutative property of multiplication states that the order in which values are multiplied does not matter and will result in the same answer. That is to say: a * b = b * aAssociative Property: The associative property of multiplication states that when three or more numbers are multiplied, the order in which the multiplication occurs has no effect on the answer. That is to say: (a * b) * c = a * (b * c)Distributive Property: Students are asked to create two groups of six (2 x 6) using connecting cubes and to locate two hidden facts inside the 2 x 6 such as 2 x 3 and 2 x 3. That is: 2 x 6 = 2 x 3 + 2 x 3.Thus, the properties of operations to multiply the expression are commutative property, associative property, and distributive property.

from 5 5/8 troy ounces of gold alloy?
Solve the problem mathematically by finding the quotient.
Answers
The Jeweler makes the number of Pendants from the total weight of gold alloy = 12
The Jeweler has the total weight of gold alloy = 5 [tex]\frac{5}{8}[/tex] = 45/8 troy ounces.
Weight of a single gold alloy pendant = 15/32 troy ounces.
Jeweler makes the number of Pendants from the total weight of gold alloy = 45/8 ÷ 15/32.
Dividing Fractions by Fractions
We just learned how to divide fractions by taking the reciprocal. Now, let us see the method of dividing fractions by fractions with an example. Have a look at the formula of the division of a fraction by fraction given below. If x/y is divided by a/b, this implies,
x/y ÷ a/b
⇒ x/y × b/a (reciprocal of a/b is b/a)
⇒ xb/ya
Now, if we need to divide: 5/8 ÷ 15/16, we will substitute the values of the given numerators and denominators.
45/8 ÷ 15/32 = 45/8 × 32/15 = 12
∴ The value of 45/8 ÷ 15/32 = 12.
Hence the Jeweler makes the number of Pendants from the total weight of gold alloy = 12

A taxi ride cost a customer a total of \$13.73$13.73dollar sign, 13, point, 73, which included 4\%4%4, percent sales tax and then a \$1$1dollar sign, 1 surcharge. What was the subtotal before the surcharge and sales tax?
Answers
The subtotal before the surcharge and sales tax is $12.2
How to determine the subtotal amount?In this question, we have the following parameters
Total = $13.73
Sales tax = 4%
Surcharge = $1
The above parameters imply that:
Total = Subtotal * (1 + sales tax) + Surcharge
Substitute the known values in the above equation, so, we have the following representation
13.73 = Subtotal * (1 + 4%) + 1
This gives
Subtotal * (1 + 4%) = 12.73
Divide both sides by 1.04
Subtotal = 12.2
Hence, the subtotal is $12.2

What is reflection?Reflection is one of the movements in transformation that involve creation of mirror image
Transformation rule for reflection over x-axis at origin (0, 0)) is
(x, y) → (x, -y)
Transformation rule for reflection over line y-axis at origin (0, 0)) is
(x, y) → (-x, y)
The reflection to be done is over line x = -3
However, reflection over line x = -3 which is (-3, 0) is done as follows
from -2 to -3 = -2 - -3 = 1 unit
reflecting 1 unit over x = -3
-3 - 1 = -4
(-4, -2)
(-2, -2) ⇒ (-2 - -3, -2) ⇒ (1, -2) ⇒ (-3 - 1, -2) → (-4, -2)
from -1 to -3 = -1 - -3 = 2 units
reflecting 2 units over x = -3
-3 - 2 = -5
(-5, 1)
(-1, 1) ⇒ (-1 - -3, 1) ⇒ (2, 1) ⇒ (-3 - 2, 1) → (-5, 1)
The calculation is simply saying put
(-2, -2) this point is just before the reflection line, the image will formed at the point just after the reflection line -3 which is -4 hence (-4, -2)

x = 18
y = 42
Step-by-step explanation:
Angle ACD = 138°
(5x + 2) + (2x + 10) = 138
7x + 12 = 138
7x = 126
x = 18
y + (5x + 2) + (2x + 10) = 180 (sum of adjacent angles on a straight line)
Substitute x = 18 into the equation.

Assume that females have pulse rates that are normally distributed with a mean of μ-750 beats per minute and a standard deviation of e=125 beats per minute. Complete parts (a) through (c) below
B. If 4 adult females are randomly selected, find the probability that they have pulse rates with a mean between 69 beats per minute and 81 bears per minute
Answers
The probability that these four females have pulse rates with a mean between 69 beats per minute and 81 bears per minute, using the normal distribution and the central limit theorem, is of:
0.663 = 66.3%.
Normal Probability DistributionThe z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The parameters for the problem are given as follows:
[tex]\mu = 75, \sigma = 12.5, n = 4, s = \frac{12.5}{\sqrt{4}} = 6.25[/tex]
The probability that these four females have pulse rates with a mean between 69 beats per minute and 81 bears per minute is the p-value of Z when X = 81 subtracted by the p-value of Z when X = 69, hence:
X = 81:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
Z = (81 - 75)/6.25
Z = 0.96
Z = 0.96 has a p-value of 0.8315.
X = 69:
Z = (69 - 75)/6.25
Z = -0.96
Z = -0.96 has a p-value of 0.1685.
0.8315 - 0.1685 = 0.663 = 66.3%.

Step-by-step explanation:
The interior and corresponding exterior angle of a triangle are always supplementary.
Therefore, we can set the sum of the two given angle measures to 180°:
[tex](2m-12) \textdegree + (3m+7) \textdegree = 180 \textdegree[/tex]
and solve algebraically for m.
[tex]2m-12 + 3m+7 = 180[/tex]

Answers
The required speed is 45 mph in each direction.
What is speed?
The definition of speed is a measurement of how quickly an object's location changes in any direction. Speed is defined as the ratio of distance to the amount of time it took to cover that distance.
We know that distance=rate*time
d=rt
45=rt
45=(r+30)(t-2)
rt=(r+30)(t-2)
This shows,
rt=rt+30t-2r-60
0=30t-2r-60
if 45=rt, then r=45/t
substitute in the equation
0=30t-2(45/t)-60
multiply both sides by t
0=30t²-90-60t
on solving this quadratic equation, we get t= 3 s, t=-1 s

Answer:
m∠1 = 126°
m∠2 = 154°
Step-by-step explanation:
First, find the measure of angle that is supplementary to ∠1. (I will call it ∠A)
We know that the measures of the interior angles of a triangle add to 180°.
Therefore,
m∠A + 96° + 30° = 180°
m∠A + 96° = 150°
m∠A = 54°
From this value, we can solve for m∠1, since it is supplementary to ∠A:
m∠A + m∠1 = 180°
54° + m∠1 = 180°
m∠1 = 126°
To solve for ∠2, we must first solve for the adjacent supplementary angle that I have named ∠B.
First, the measures of the interior angles of a triangle add to 180°:
28° + m∠1 + m∠B = 180°
28° + 126° + m∠B = 180°
m∠B = 26°
Finally, we can solve for m∠2 because it is supplementary to ∠B.
m∠B + m∠2 = 180°
26° + m∠2 = 180°
m∠2 = 154°

What is mean, median, mode and range?The "mean" is the standard "average," which is calculated by adding up all the numbers and dividing the result by the total number of numbers.
The value that sits in the middle of a set of numbers is known as the "median." Before you can find the median, your numbers must be listed in numerical order from smallest to greatest. This means that you might need to redo your list.
The "mode" value is the one that shows up the most often. There is no mode for the list if no number on the list is repeated.
A list of numbers' "range" is just the range between the largest and lowest values. It conveys "spread," which is the degree to which the values are scattered (or how concentrated they are).
Mean=(3+6+9+7+4+6+7+0+7)/9
Mean = 49/9

Since the congruent angle is a right angle and it is not included, the two congruent sides of the triangles must include their hypotenuses and one of their legs.The triangles would be congruent by the hypotenuse leg theorem, which states that if the hypotenuse and one leg of a right triangle is congruent to the hypotenuse and a leg of another right triangle, the triangles are congruent.Answer:hypotenuse leg theorem
