The factor when Bradley is trying to find a missing factor a product is odd.
How to illustrate the information?From the information given, the product of that factor has a ones digit = 3. From the information, we have to find whether the missing factor is even or odd.
We know that, the product of two odd numbers is odd. The product of two even numbers is even.
The product of one even and one odd number is even.
If one digit of a number is odd then the number must be odd.
It means factors of odd numbers are odd.
If the product of that factor has 3 in the ones digit then, the missing factor will be odd.

Question 10 (1 point)Givenm
The measure of angle ∠AOB is 139 degrees, that is the value of m∠AOB is 139.
We are given;
m∠AOC is a straight line = linear pair
m∠AOB = 8x + 51 degree
m∠BOC = 6x - 25 degree
We know that sum of the angles of linear pair is 180 degrees.
So,
∠AOB + ∠BOC = 180 degrees
8x + 51 degree + 6x - 25 degree = 180 degrees
14x = 180 - 26 degrees
x = 154/14 degrees
x = 11 degrees
Therefore,
m∠AOB = 8x + 51 degree = 8 * 11 + 51 degrees = 139 degrees.
m∠BOC = 6x - 25 degree = 6 * 11 - 25 degrees = 41 degrees.
Thus, the measure of angle ∠AOB is 139 degrees, that is the value of m∠AOB is 139.

1A shipment of sugar fills 4 1/5containers. If each container holds 2 1/3 tons of sugar, what is the amount of sugar in the entire shipment? Write your answer as a mixed number in simplest form
Answer:
9 4/5 tons of sugar.
Explanation:
The number of containers in a shipment of sugar = 4 1/5 containers
Amount of sugar in each container = 2 1/3 tons
Therefore, the amount of sugar in the entire shipment is:
[tex]\begin{gathered} =4\frac{1}{5}\times2\frac{1}{3} \\ =\frac{21}{5}\times\frac{7}{3} \\ =\frac{7\times7}{5} \\ =\frac{49}{5} \\ =9\frac{4}{5}\text{ tons} \end{gathered}[/tex]There are 9 4/5 tons of sugar in the entire shipment.
Regular pentagon HIJKL is shown below. What is the measure of ANGLE HIK? (image attached)A. 36 degreesB. 54 degreesC. 72 degreesD. 108 degreesthank you ! :)
Given a regular pentagon HIJKL.
We are asked to find the measure of Angle HIK
To find the measure of a central angle of a regular pentagon, we make a circle in the middle of the pentagon. We know that a circle is 360 degrees around.
Now, we will divide the 360 by the five angles. Now, the measure of each central angle is equal to:
360/5
So,
Angle HIK = 360/5
Angle HIK = 72˚
Therefore, the correct option is C, which is 72˚.

Step-by-step explanation:
Which expression is not equivalent to 2rº + 10x + 12? (1) (2x + 4)(x + 3) (3) (2x + 3)(x + 4) (2) (2x + 6)(x + 2) (4) 2(x + 3)(x + 2)
(2x + 3)(x + 4) = 2x² + 8x + 3x + 12 = 2x² + 11x + 12 ≠ 2x² + 10x + 12
So, the expression (2x + 3)(x + 4) is not equivalent to 2x² + 10x + 12

Explanation:
A formula describes a function that is nonlinear if the exponent of the variable is greater than 1.
Therefore, the geometric formulas that describe functions that are nonlinear:
A = 6s²
V = (4/3)πr³
Because the variable s has an exponent equal to 2 for the first one and the variable r has an exponent equal to 3 for the second one.

point (0,6) in which quadrant and axis
Given the point:
(0, 6)
Let's find the quadrant and the axis where the point is located.
We have:
(x, y) ==> (0, 6)
The x-coordinate of the point is 0, while the y-coordinate of the point is 6.
Here, the point (0, 6) lies on the y-axis.
Also, since the x-coordinate is 0, we can say the point lies in between quadrant I and quadrant II.
From the graph above we can see the point (0, 6) is between quadrant I and II, and the point lies on the y-axis.
ANSWER:
• The point is in beween Quadrant I and II
,• The point lies on the y-axis.

A farmer is telling a rectangle field that is 63 yards long and 60 yards wide what is the distance between opposite corners of the farmers field?
87 yards
Explanations:
Given the following parameters:
• Length of the rectangle = 63 yards
,• Width of the rectangle = 60 yards
The distance between opposite corners of the farmer's field is the diagonal of the rectangle.
To determine the diagonal of the rectangle (d), we will use the Pythagoras theorem:
[tex]\begin{gathered} d^2=l^2+w^2 \\ d^2=63^2+60^2 \\ d^2=3969+3600 \\ d^2=7,569 \\ d=\sqrt[]{7,569} \\ d=87yards \end{gathered}[/tex]Hence the distance between opposite corners of the farmers' field is 87 yards

The distribution of the binomial random variable (x) has the following parameters: p = 0.3 and n = 9 Determine the P(X ≥ 2)
Answer:
Explanation:
The formula for calculating binomial probability is expressed as
P(x) = nCx * p^x * q^(n - x)
where
n is the number of trials
x is the number of successes
p is the probability of success
q is the probability of failure
From the information given,
n = 9
p = 0.3
q = 1 - p = 1 - 0.3 = 0.7
By using a binomial probability calculator,
P(x ≥ 2) = 0.804

What is delivery ?
Transporting items from a source point to a predetermined destination is known as delivery. Roads, railroads, shipping lanes, and airline networks all play major roles in the delivery of cargo (physical products). Specialized networks, such as pipelines for liquid products, power grids for electrical power, computer networks like the Internet, or broadcast networks for electronic information, may be used to distribute specific sorts of goods. [1] A specific subcategory is car transport, and an associated variation is autorack, which involves shipping cars through railroad.
Delivery, which comprises both transportation and distribution, is a crucial aspect of trade and commerce.Distribution is the overall process of providing things, while logistics is the study of efficient delivery and disposition procedures for both persons and materials. Distributors are companies that specialize in moving commercial items from their site of manufacture or storage to their point of sale, whereas delivery services are companies that focus on moving goods to consumers. Deliveries of goods for both commercial and private purposes are also made by postal, courier, and moving services.
According to the question
The new refrigerator delivered to his home for $950
tip he gave to the delivery person = $20
let tip he gave to the person in percentage be x
$20= [tex]\frac{x}{100}(950)[/tex]
