Area of the bigger trapezoid = (6 + 2) x 1/2 x 6 = 8 x 1/2 x 6 = 4 x 6 = 24
Area of the smaller trapezoid = (4 + 2) x 1/2 x 3 = 6 x 1/2 x 3 = 3 x 3 = 9
Area of the shaded area = 24 - 9 = 15Hope that helps! :)

Graph the solution to this inequality on the number line.
The
Using a straight line and either an open circle or a closed circle to indicate the end points, we can depict inequalities on a number line by displaying the range of integers.
How do you identify inequalities?By drawing a straight line and designating the end points with either an open circle or a closed circle, we can depict inequalities on a number line by illustrating the range of integers. An open circle indicates that it excludes the value. A closed circle indicates that it does contain the value.
Both equations and inequalities are mathematical phrases created by connecting two expressions. The equal sign (=) in an equation denotes that the two expressions are regarded as equal. In contrast, an inequality indicates that the two phrases are not always equal by using the symbols >,,, or.
With regard to the inequality expression
-3m + 5 > 14
5 from each side is subtracted.
-3m + 5 - 5 > 14 - 5
-3m > 9
Subtract -3 from both sides.

After evaluating the given expressions the results could be 245 / 89 , 43/6, 33/4 .
What is expression ?
expression can be defined as with the minimum of two variables or numbers and at least one math operation.
Given that ,
7/ 8 * 14 / (3/8 * 6 ) + 2 1/5
= (7/8 * 14 )/ ((18 / 8) + 11/5)
= (98/ 8 ) / (90 + 88) / 40
= (98/ 8 ) / (178/ 40)
= (98 * 40) / (8* 78)
= 245/89
Hence the final value could be 245/53.
7/ 8 + (6*7/8 - 4 * 3/16 ) / (3/4 )
(7/8 + (21/4 - 3/4 ) ) / (3/4)
(7/8 + 18/4) / (3/4)
(43/8) / (3/4)
43/6
Hence the final value could be 43/6.
3 1/7 * (3 1/3 * (2/3 + 1/6 ) - 5/18 ) / 2 (3/7)
11/7 * (10/6 - 5/18) / (17/7)
(11/7 )* (27/ 18) /( 17/7)
(11* 27/18 )/ (17)
33/34.
Hence the final value could be 33/34.

How much is the difference between the account balances after 3 years?
Answer:
3450 because 5 percent of 3000 Is 150
Answer:
Hey, the answer is 15.375
Step-by-step explanation:
UsiNg PRT/100, the simple interest of the sum of 3000 naira invested for 3yrs at 5% per annum is 450.
Meanwhile, the first year of the compound interest, the interest generated was 150
second year 157.5

Which shape is NOT a trapezoid? I
Answer:
a shape that is not a trapezoid is a a square or a triangle
Step-by-step explanation:
Between 2020 and 2021, the population of a town decreased by 35%
In 2021, the population of the town was 94 900. What was the population of the town in 2020?
Answer:
Step-by-step explanation:
if 2021 is 35% decrease of the original number then 2020 is 100% ,and 2021 = 65%.
so, we do the rule of three:
x = (94900 * 100)/ 65
x = 146000
and that is the population in 2020.
Answer:
Hey there! Based on the information provided, it seems that the population of the town decreased by 35% between 2020 and 2021. We can use this information to calculate that in 2021, the population of the town was 65% of its population in 2020. If the population of the town in 2021 was 94,900, then we can use this information to calculate that the population of the town in 2020 was 146,155. Does that make sense?
s/4 +5=13
How do i solve thissssssss
[tex]\dfrac{s}{4} +5=13[/tex]
Simplify:
[tex]\dfrac{1}{4} s+5=13[/tex]
Subtract 5 from both sides:
[tex]\dfrac{1}{4} s+5-5=13-5[/tex]
[tex]\dfrac{1}{4} s=8[/tex]
Multiply both sides by 4:
[tex]4\times(\dfrac{1}{4} s)=4\times(8)[/tex]
[tex]\fbox{s = 32}[/tex]
s = 32.
Step-by-step explanation:1. Write the expression.[tex]\frac{s}{4} +5=13[/tex]
2. Subtract 5 from both sides of the equation.[tex]\frac{s}{4} +5-5=13-5\\ \\\frac{s}{4} =8[/tex]
3. Multiply by "4" on both sides of the equation.[tex]\frac{s}{4}*4 =8*4\\ \\s=32[/tex]
4. Verify.If the result is correct, then the equation should return the same value of both sides of the equal symbol (=) when we substitute the variable "s" by it's calculated value, 32.
[tex]\frac{(32)}{4} +5=13\\ \\8+5=13\\ \\13=13[/tex]
As you can tell, the same number appears on both sides of the equal symbol, this means that the result is correct!

Choose a topic for you survey.
Determine and write 5 relevant questions to include in your survey.
* Write 2 flawed survey questions and identify what makes each one flawed. Then rewrite each question so it is no longer flawed.
*Write 3 survey questions that are not flawed.
Choose and describe an appropriate sampling method and explain why this method was chosen and how it will ensure an unbiased sample.
Answer:
The difference between a flawed and non-flawed survey question is usually bias; you don't want the question to seem like it's leading the reader to any one answer, it should be worded neutrally. The best method to find non-biased samples is to select your samples randomly.
Which statements are true? Select three options.
and are parallel.
Answer: line AB and RS are parallel because their lines do not interact anywhere on the model, because it is 3D. this is the only one i am sure of, you may have to ask another person to get the other two.
Answer:
A. Line AB and Line CG are parallel, C. Line CG and Line RS are perpendicular, and E. Line CG lies in plane X
Step-by-step explanation:
A. Line AB and Line CG are parallel is true because the arrows are pointing in the same directions and do intersect or cross each other.
B. Line AB and Line RS are parallel is false because although they do not intersect, they also do not go in the same direction. These are also not perpendicular lines because they do not intersect other, even though they make a right angle.
C. Line CG and Line RS are perpendicular is true because these lines intersect at exactly 90° angle (as shown by the square).
D. Line AB and Line RS must intersect is false because Line AB does not intersect Line CG (which is the line that does intersect Line RS).
E. Line CG lies in plane X is true because point C and point G are in plane X.
F. Line RS lies in plane X is false because point r and point 2 are in plane Y.
Write an equation in standard form passing through the given point and parallel to the given line: (-1,-1) y = - x - 5
A: x - y = -2
B: x + y = 0
C: x - y = 0
D: x + y = -2
Option D, x + y = -2 is the equation in standard form passing through the (-1,-1) and parallel to y = -x - 5.
What is standard form?The process of expressing a specific element in mathematics in the most typical way is known as standard form. Every element of mathematics, including big and small numbers, equations and lines, is designated in a standard form.
A standard form is a way of expressing a certain mathematical idea, such as an equation, number, or expression, in a way that adheres to a set of rules. The standard form is used to clearly represent extremely large or extremely small numbers.
To write an equation in standard form passing through the (-1,-1) and parallel to y = - x - 5, we need to find y-intercept form first
We know that parallel lines have same slope, so
y - y1 = m(x - x1)
y -(-1) = -1(x -(-1)
y + 1 = -x - 1
y = -x - 2
y + x = -2
Thus, Option D, x + y = -2 is the equation in standard form passing through the (-1,-1) and parallel to y = -x - 5.

CORRECT ANSWER
PROVIDE EXPLANATION
The length of x of a diagonal support is 13.8 feet.
What is the hypotenuse of a triangle.The hypotenuse of a triangle is the length of the longest side of the triangle. So that it is always opposite to the measure of the largest angle of a triangle.
In the question given, divide the length of the footbridge into 2 parts.
So that,
Half of the footbridge = 25/ 2
= 12.5 ft
So that applying the appropriate trigonometric function to determine the value of x using any of the congruent triangles. We have;
Sin θ = opposite/ hypotenuse
Sin 65 = 12.5/ x
x = 12.5/ Sin 65
= 12.5/ 0.90631
x = 13.792 feet
