Answer:
140
Explanation:
an=-12+4(n-2)
an=-12+4([40]-2)
an=-12+4(38)
an=-152-12
an=140
The 40th term in the sequence defined by aₙ= -12+4(n-2) is 140
using AP formula,
aₙ = a + (n - 1)d
where
a = first term
d = common difference
n = number of terms
Therefore,
aₙ = -12 + 4(n-2)
n = 40
a₄₀ = -12 + 4(40 - 2)
a₄₀ = -12 + 4(38)
a₄₀ = -12 + 152
a₄₀ = 140
The 40th term of the sequence is 140.

if there are 362 men and 73 women what percentage of women are there
Answer:
16.78%
Step-by-step explanation:
Total = men+women
= 362+73 = 435
Percentage: 73/435 × 100
= 16.78%
Answer:
20%
Step-by-step explanation:
Use 362 as 100% since it is the output value and use 73 as a x value then put them into the equation 100%/x% = 362/73 then flip the equation x%/100% = 73/362

I feel it could be AAS since both angles could be alternate interior but it could also be SAS so could someone help please?
Answer: D) Side-Angle-Side (SAS)
Check out the diagram below. Note the color coding to see how the angles and sides correspond to the given information. We aren't given RT = RT, but we use the reflexive property in this case. The angles are between the sides so we use SAS.
We don't have enough information to determine anything about the other angles, so we cannot use AAS or ASA. Also, recall that SSA is not a valid congruence theorem. Luckily the angle is between the sides so we don't have to worry about SSA.

Therefore, the area of a sector of a circle would be 13.5π square units.
Step-by-step explanation:
Given
[tex]r=9[/tex] miФ = 60°The area of a sector of a circle is:
A = π r² Ф/360
A = π (9)² 60/360
A = π 81 * 1/6

The area of the rectangle flower bed shown is
20.4 square meters. How many meters of edging are needed to go around the flower bed?
Answer:
I think 5.4
Step-by-step explanation:
Take it and divide by the number of sides
The Perimeter of rectangle is 27.4 m
What is Area of rectangle?The area of rectangle is product of its length to tis width.
So, Area of rectangle = length x width
Given:
Area of the flower bed = 20.4 square meters.
length = 12 m
As a rectangle, its area be
A = l x w
20.4 = 12 w
w= 20.4/ 12
w= 1.7
Now, Perimeter of rectangle
= 2( l + w)
= 2( 12+ 1.7)
= 27.4 m
Hence, the Perimeter of rectangle is 27.4 m

IQ test scores are standardized to produce a normal distribution with a mean of = 100 and a standard deviation of = 15. Find the proportion of the population for the following IQ score. For your answer, convert each proportion into a percentage whose value is computed to 2 decimal places. Sketch a distribution to help you visualize the problem. IQ score greater than 135
Answer:
0.01
Step-by-step explanation:
Using the z score formula
z = (x-μ)/σ,
where x is the raw score = 135
μ is the population mean = 100
σ is the population standard deviation = 15
z = 135 - 100/15
z = 2.33333
P-value from Z-Table:
P(x<135) = 0.99018
P(x>135) = 1 - P(x<135)
P(x > 135) = 1 - 0.99018
= 0.0098153
Approximately to 2 decimal places
= 0.01
Therefore, the proportion of the population for the following IQ score of 135 is 0.01
Which system of inequalities can model Gabrielle’s situation, where x represents batches of brownies and y represents batches of cookies?
Answer:
2x + 2y ≤ 20
x + 3y ≤ 2
Step-by-step explanation:
this is the correct answer i got on my assignment-------
The system of inequalities can model Gabrielle’s situation is x + 2y ≤ 20
and 3x + 2y ≤ 21.
What are inequalities?The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than’, or < ‘less than’.
It follows from the task content, that the inequalities which can be used to model Gabrielle's situation be determined.
By setting variables as follows; batches of brownies = x and batches of cookies = y
Brownie:
Sugar = 1 cup
Eggs = 2
x + 2y ≤ 20
Cookie:
Sugar = 3 cups
Eggs = 2
3x + 2y ≤ 21
