s the Administrator for Cloud Computing, you have created a custom object that is the detail object in a master-detail relationship with Account. What is TRUE about the OWD setting for the custom object
In the scenario where a custom object is the detail object in a master-detail relationship with Account, the Organization-Wide Default (OWD) setting for the custom object would be controlled by the OWD setting of the master object, which is Account.
In Salesforce, the Organization-Wide Default (OWD) setting determines the default level of access for records of an object within an organization. When a custom object is set as the detail object in a master-detail relationship with Account, the OWD setting for the custom object will be controlled by the OWD setting of the master object, which is Account in this case.
The OWD setting for Account will dictate the level of access for the related records of the custom object. For example, if the OWD setting for Account is set to "Private," the related records of the custom object will also inherit the "Private" access level. This means that only users with appropriate sharing interest, such as those assigned to Account roles or sharing rules, will have access to the related records of the custom object.

Answer:
y = 2
x = -3.5
Step-by-step explanation:
3y and (2x + 13) are same-side angles.
that means they are equal
(that's not the real term for it, I just forgot what it's called)
using that, you can make this equation:
3y = 2x + 13
3y - 13 = 2x
(3y - 13)/2 = x
(5y - 4) and 3y are vertical angles.
vertical angles are equal.
using this, you can make the following equation:
5y - 4 = 3y
5y - 3y - 4 = 0
5y - 3y = 4
2y = 4
y = 2
now, substitute y for 2 in the original equation.
(3y - 13)/2 = x
(6 - 13)/2 = x
-7/2 = x
-3.5 = x
How do you learn 4x tables?
When you multiply 4 with any number, you can use the doubling-up trick (that's the one you used for the two times table) twice. Here is an example: 2 x 4 is the same as 2 + 2 = 4 and then 4 + 4 = 8. So, 2 x 4 = 8.
Here is next double, double example are: 5 x 4 is the same as 5 + 5 = 10, so then 10 + 10 = 20. So, the answer is 5 x 4 = 20.

Find the next four terms in the arithmetic sequence 1/4, 3/4, 5/4
Answer:
7/4, 9/4, 11/4, 13/4
Step-by-step explanation:
+ In an arithmetic sequence, to find the pattern you must subtract a term from the term after it to find the common difference.
3/4 subtracted from 5/4 is 2/4
1/4 subtracted from 3/4 is 2/4
+ So the common difference is 2/4 (Aka 1/2, but you want to keep the same denominator)

Daniela, Kieu, and Cameron decide to go to the movies one hot summer afternoon. The theater is having a summer special called Three Go Free. They will get free movie tickets if they each buy a large popcorn and a large soft drink. They take the deal and spend a total of $22.50 on large popcorns and soft drinks. The next week, they go back again, only this time, they each pay $8 for a ticket, they each get a large soft drink, but they share one large bucket of popcorn. This return trip costs them a total of$37.50. Use systems of equations to find the price of a large soft drink and the price of a large bucket of popcorn!
Answer:
Price of a large soft drink = $3
Price of large bucket of popcorn = $4.5
Step-by-step explanation:
Let the cost of one large popcorn = $P
And the cost of one large soft drink = $S
If Daniela, Kieu and Cameron avail the deal of Three Go Free,
3P + 3S = 22.50
P + S = 7.5 -----(1)
Next time they each pay $8 for a ticket, they each get a large soft drink but they share one large bucket of popcorn.
This trip cost them = $37.50
Cost of 3 tickets + Cost of 3 large soft drinks + Cost of one large bucket of popcorn = 37.50
(3 × 8) + (3 × S) + P = 37.5
24 + 3S + P = 37.5
3S + P = 13.5 -----(2)
By subtracting equation (1) from equation (2),
(3S + P) - (P + S) = 13.5 - 7.5
2S = 6
S = $3
From equation (1),
P + 3 = 7.5
P = $4.5
Therefore, price of a large soft drink is $3 and a large bucket of popcorn is $4.5

a. (0, 3), (1, 12), (2, 48), (3, 192), and (4, 768)
The exponential function for each set of points is y = 3 * 2ˣ,
What is the exponential function?
An exponential function is a Mathematical function in form f (x) = ax, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.
The exponential function can be described as y = 3 * 2ˣ,
where,
x is the input value
and y is the output value.
This function says that for every increase in x by 1 unit, the value of y will be multiplied by 2, starting from an initial value of 3.
For example, when x = 0, y = 3 * 2⁰ = 3, and when x = 1, y = 3 * 2¹ = 12.
Hence, the exponential function for each set of points is y = 3 * 2ˣ,

The length of the rectangle is 11yd less than three times the width , and the area of the rectangle 42 yd 6^2 . Find th dimension of the rectangle
Answer:
width = 6 yards
length = 7 yards
Step-by-step explanation:
Area of a rectangle = length x width
width = w
length = 3w - 11
w x (3w - 11) = 42
3w² - 11w = 42
3w² - 11w - 42 = 0
this is a quadratic equation :
Determine factors of (3w² x -42) -126w² that add up to -11w
these factors are -18w and +7w
3w² - 18w +7w - 42 = 0
3w(w - 6) + 7(w - 6)
(3w + 7) (w - 6)
w = 6
or
3w + 7 = 0
w = -7/3
since the width cannot be negative, the width would be 6 yards
length = 3w - 11
3(6) - 11
18 - 11 = 7

A city planner wants to build a road perpendicular to D Street. What should be the slope of the new road?
The slope of the new road is zero.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
Take points from the Graph (5, 0) and (5, 4).
Slope of a line = m = tanθ
where θ is the angle made by the line with the x−axis.
For a line parallel to y−axis ,θ= π/2.
∴m = tan π/2 = undefined
The new road will therefore have 0° of inclination if it is perpendicular to D street because if they are perpendicular and D street is vertical, the new road is level and has 0° of inclination.
An horizontal line now has zero slope.

You have completed 1000 simulation trials, and determined that the average profit per unit was $6.48 with a sample standard deviation of $1.91. What is the upper limit for a 89% confidence interval for the average profit per unit
The upper limit for the 89% confidence interval of the average profit per unit, based on the 1000 simulation trials, is estimated to be $6.98.
Find the upper limit of the 89% confidence interval ?To find the upper limit for an 89% confidence interval for the average profit per unit, we can use the following formula:
Upper limit = sample mean + margin of error
The margin of error can be calculated using the following formula:
Margin of error = z* (standard deviation/ sqrt(n))
where z* is the z-score associated with the level of confidence we are interested in, n is the sample size, and the standard deviation is the sample standard deviation.
To find the z-score associated with an 89% confidence interval, we can use a standard normal distribution table or a calculator. The z-score for an 89% confidence interval is approximately 1.645.
Substituting the given values in the formula, we get:
Margin of error = 1.645 * (1.91 / sqrt(1000)) = 0.099
Now, we can calculate the upper limit as:
Upper limit = sample mean + margin of error = 6.48 + 0.099 = 6.579
Therefore, the upper limit for an 89% confidence interval for the average profit per unit is $6.579.

How do we convert 1 g/cm3 to kg/m3
The units g/cm3 and kg/m3 are both used to express the density of a material, which is a measure of its mass per unit volume. Here's how you can convert g/cm3 to kg/m3: Multiply the density in g/cm3 by a conversion factor of 10^-3. Divide the result by a conversion factor of 100^3.
The conversion between g/cm3 and kg/m3 involves multiplying the density in g/cm3 by a conversion factor that takes into account the differences in units of mass (g vs. kg) and volume (cm3 vs. m3).
For example, let's consider the density of water, which is 1 g/cm3. To convert this density to kg/m3, we multiply by 10^-3 to get 0.001 kg/g. Then, we divide by 100^3 to get the final result: 1 g/cm3 * 10^-3 kg/g / 100^3 cm^3/m^3 = 0.001 kg/g * 1/10^9 cm^3/m^3 = 0.001/10^9 kg/m^3 = 1 kg/m^3.This is how you can convert g/cm3 to kg/m3.

Find the product of 32 and 46. Now reverse the digits and find the product of 23 and 64. The products are the same!
Does this happen with any pair of two-digit numbers? Find two other pairs of two-digit numbers that have this property.
Is there a way to tell (without doing the arithmetic) if a given pair of two-digit numbers will have this property?
Let's calculate the products and check if they indeed have the same value:
Product of 32 and 46:
32 * 46 = 1,472
Reverse the digits of 23 and 64:
23 * 64 = 1,472
As you mentioned, the products are the same. This phenomenon is not unique to this particular pair of numbers. In fact, it occurs with any pair of two-digit numbers whose digits, when reversed, are the same as the product of the original numbers.
To find two other pairs of two-digit numbers that have this property, we can explore a few examples:
Product of 13 and 62:
13 * 62 = 806
Reversed digits: 31 * 26 = 806
Product of 17 and 83:
17 * 83 = 1,411
Reversed digits: 71 * 38 = 1,411
As for determining if a given pair of two-digit numbers will have this property without actually performing the multiplication, there is a simple rule. For any pair of two-digit numbers (AB and CD), if the sum of A and D equals the sum of B and C, then the products of the original and reversed digits will be the same.
For example, let's consider the pair 25 and 79:
A = 2, B = 5, C = 7, D = 9
The sum of A and D is 2 + 9 = 11, and the sum of B and C is 5 + 7 = 12. Since the sums are not equal (11 ≠ 12), we can determine that the products of the original and reversed digits will not be the same for this pair.
Therefore, by checking the sums of the digits in the two-digit numbers, we can determine whether they will have the property of the products being the same when digits are reversed.

The base of a triangle is twice that of its height. If the area is 36 square centimeters, then find the length of its base and height.
Answer:
height = 6 cm
base = 12 cm
Step-by-step explanation:
Let the base of the triangle is denoted by b
Let the height of the triangle is denoted by h
We are given that base of a triangle is twice that of its height,
b = 2h
Recall that area of a triangle is given by,
A = ½×b×h
We are given that area of the triangle is 36 cm²
36 = ½×b×h
Substitute b = 2h in the above equation
36 = ½×2h×h
36 = h×h
h² = 36
h = √36
h = 6 cm
Therefore, the height of the triangle is 6 cm
b = 2h
b = 2(6)
b = 12 cm
Therefore, the base of the triangle is 12 cm
Verification:
A = ½×b×h
A = ½×12×6
A = ½×72
A = 36 cm²
Hence proved
