Step-by-step explanation:
A) minute 1) diameter = 7.995946004446154 mm
minute 2) diameter = 24.07378170048816 mm
(I'll assume that you can round if necessary)
B) The diameter of the new ink spot is roughly 3X larger

Each figure below is made up of congruent
trapezoids. Find the area of the figure.
Answers
Answer:
the area of trapizoid is 54 and all togather will be 108
Answer:
108 cm^2
Step-by-step explanation:
The formula for calculating the area of a trapezoid is (a+b)*h/2, a and b being the bases and h being the height.
Since the height of the figure is 12 cm, the height of each trapezoid is 12/2 = 6 cm because the trapezoids are congruent.
With this information we can calculate each trapezoid's area: (base 1 + base 2)*height / 2 = (6+12)*6/2 = 18*3 = 54 cm^2.
We know the area of one trapezoid is 54 cm^2, so two trapezoids would have an area of 108 cm^2 (the figure is composed of two trapezoids).

A popular art teacher at a school asks a sample of students if they would be interested in taking an art class next year. Of the 30 students he asks, 85% are in one of his art classes this year. Only 15% of the students in the school are in one of his art classes this year. Will this sample be biased? *
Yes, because students who are in one of his art classes this year will be more likely to take one of his art classes next year.
No, because students who are in one of his art classes this year will be less likely to take one of his art classes next year.

Step-by-step explanation:
Luz drives at an average speed of 60 miles per hour.
She has driven for 2 hours and has traveled a distance of 120 miles.
This situation can be represented with a linear equation written in point-slope form, where x represents the number of hours and y represents the number of miles.
Use this information to complete each statement about the linear equation
Answers
Answer:
1) This linear equation has a slope of 60
2) (2, 120)
3) [tex]y - 120 = m(x - 2)[/tex]
Step-by-step explanation:
1) This situation represents a linear time-distance relationship where:
x represents the time
y represents the distance travelled
Slope is equal to △y/△x
Substituted form: [tex]\frac{120}{2}[/tex]
Slope is equal to 60.
2) Using the statement:
She has driven for 2 hours and has traveled a distance of 120 miles, we know that knowing that x represents the time and y represents the distance:
A possible coordinate is (2, 120)
3) Using the point slope standard equation and our known values, we can substitute the values. The correct answer is y - 120 = m(x - 2)

The answer most likely is 80
Step-by-step explanation:
By useing a bit of geometry instead of useing two angles to find your last angle.
So first notice how there are two of the same sides (14)but one differnt side(18) okay nice
With that info it is clear that it is a isosoles triangle (triangle with two equal sides and angles) so from that information two of the angles are gonna be the same. Luckely you were given an angle.
So that means there are two 50 angels and an X angle and to solve for X angle you need to add 50 + 50 = 100 then subtract to 180 then boom 80

1/6, 5/6, 1 3/6, ...
A.1 5/6
B.2 2/6
C.2 4/6
D.2 1/6
Answers
Answer:
D. 2 1/6
Step-by-step explanation:
To visualize the problem easier, start by converting all the fractions to improper fractions, this will allow you to just add the denominators and simplify the question:
1/6, 5/6, 1 3/6 —> 1/6, 5/6, 9/6
Now that the sequence is rewritten, you can simply add 4 to the numerator, which equals 13/6.
Rewrite this again by finding how many times 6 goes into 13, and use the remainder as the numerator of the new fraction, which will end up as 2 1/6.
A box of cereal measures 8 in by 3 in by 10 in. 80% of it is filled with cereal. How much cereal is in the box?
Answers
Answer:
192
Step-by-step explanation:
The area of the cereal box = 8 x 3 x 10 = 240
Therefore, if 100% of the box is filled with
cereal, the amount of cereal in the box
will be 240.
now, 80% is x
80/100 = x/240
cross multiplying,
100x = 80×240
100x = 19 200
dividing both sides by 100
x = 192

41n(7x) = 8
Remove parenthesis around (7x)
41n * 7x = 8
Reorder the terms for easier multiplication:
41 * 7n * x = 8
Multiply 41 * 7
287n * x = 8
Multiply n * x
287nx = 8
Solving
287nx = 8
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Divide each side by '287x'.
n = 0.02787456446x-1
Simplifying
n = 0.02787456446x-1

Which of the points below does not lie on the graph of the line –2x + 3y = 6?
25 points
Answers
If we substitute the x and y value from B into the equation; ( 6 = x and -2 = y), both sides of the equation will not be equal;
-2x + 3y = 6
-2 (6) + 3(-2) = 6
-12 + (-6) = 6
-18 = 6
Since both sides of the equal sign are not 6, the point does not lie on the line.
