The next two terms of the sequence 0.3, -0.09, and 0.0027 are -0.00027 and 0.000027, achieved by continuously multiplying each term by -1/10.
Explanation:To find the next terms of the sequence 0.3, -0.09, and 0.0027, you need to understand the pattern in the sequence. Here, each term is multiplied by -1/10 (or -0.1) to get the next term. So, to find the next term, we multiply the last given term (0.0027) by -1/10, which gives -0.00027. Therefore, the fourth term of the sequence is -0.00027. For the fifth term, we do the same process and multiply -0.00027 by -1/10, to get 0.000027. So, the next two terms in the sequence are -0.00027 and 0.000027.

A painter is working on a canvas that has a total area of 338 square inches. The canvas is x inches wide and twice as long as it is wide. Find the value of x.
A) 13
B) 18.4
C) 112.7
D) 69
Answer:
C
Step-by-step explanation:
Area = 338
Width = X
Length = 2x
2x * x = 338
3x = 338
x = 112.7
The value of x from the rectangular shaped canvas box is x = 13 inches
What is the Area of a Rectangle?The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
Let the area of rectangle canvas be A = 338 inches²
Let the width of the canvas = x inches
And , length = 2 x ( width )
Now , the length of the canvas = 2x inches
So , Area of Rectangle = Length x Width
On simplifying , we get
Area of Rectangle = 2x ( x )
Area of Rectangle = 2x²
338 = 2x²
Divide by 2 on both sides , we get
x² = 169
Taking square roots on both sides , we get
x = 13 inches
Hence , the value of x of the canvas is 13 inches

solve 4x-9=k for x
Answer:
The value of x is [tex]\frac{k+9}{4}[/tex]
Step-by-step explanation:
Given : equation 4x - 9 = k

B is between A and C, D is between B And C, and C is between B and E. AE = 28cm, BC =10cm. AB = DB = DC. what is the length of CE ?
Final answer:
By using the given lengths of AE and BC, along with the equality of AB, DB, and DC, we can solve for CE to be 14.67cm.
Explanation:
The lengths of AE, BC, AB, DB, and DC are given or can be determined with the information provided. Since AB = DB = DC and BC is given as 10 cm, we can deduce that AB + BC + CE = AE. Given AE is 28cm and BC is 10cm, we can find the length of AB by realizing that AB + AB + AB (which is AB + DB + DC) is the same as BC or 10cm. This makes each section AB, DB, and DC equal to 10cm / 3.
With AB, DB, and DC all being equal to 10cm / 3, and knowing AE is 28cm, we can then calculate the length of CE:
AE = AB + BE (and BE = BC + CE)
28cm = (10cm/3) + (10cm + CE)
To find CE, rearrange the equation:
CE = 28cm - 10cm - (10cm/3)
CE = 28cm - 10cm - 3.33cm
CE = 18cm - 3.33cm
CE = 14.67cm
To solve for the length of CE in a line segment configuration, we calculate CE = AE - BC - DC after determining the lengths of AB, BC, and DC. The solution reveals that CE is 9cm.
Explanation:The student has a geometry problem, which involves calculating the length of segment CE on a line segment AE. We know that AE = 28cm and BC = 10cm, with AB, DB, and DC being equal in lengths.
Since B is between A and C, and D is between B and C, and C is between B and E, we can write the entire length AE as AB + BC + CE. Because AB = DB = DC, we can substitute DB and DC for AB in the sums to get 2(DB) + BC = 28cm.
We are given that BC = 10cm, so we can set up an equation: 2(DB) + 10cm = 28cm. Solving for DB, we find that DB = 9cm. Since DC is equal to DB, DC is also 9cm. CE can be found by subtracting BC and DC from the total length of AE: CE = AE - BC - DC, so CE = 28cm - 10cm - 9cm, resulting in CE = 9cm.
which of the following are necessary when proving the opposite angles of a parallelogram are congruent? Check all that apply.
A) Opposite sides are perpendicular
B) Corresponding parts of similar triangles are similar
C) Opposite sides are congruent
D) Corresponding parts of congruent triangles are congruent
The opposite angles of a parallelogram are congruent this can be proved by the fact that;
Opposite sides are congruent Corresponding parts of congruent triangles are congruentTo prove opposite angles in a parallelogram are congruent, it's necessary to recognize that opposite sides are congruent and use the property that corresponding parts of congruent triangles are congruent.
Explanation:To prove that the opposite angles of a parallelogram are congruent, it's not necessary that opposite sides be perpendicular. Instead, let's consider the properties that are relevant to this proof:
Opposite sides are congruent (C)Corresponding parts of congruent triangles are congruent (D)In this case:
Option A is not relevant because a parallelogram does not require opposite sides to be perpendicular; that is a characteristic of a rectangle.Option B refers to similar triangles, which is not necessary for proving the opposite angles are congruent in parallelograms. Similar triangles have proportional sides and identical angles, which is not the focus here.Option C is a defining property of parallelograms and is necessary to help prove that opposite angles are congruent.Option D can be used in the proof if one demonstrates that two triangles within the parallelogram are congruent, therefore their corresponding angles must be congruent; this includes the opposite angles of the parallelogram.The proper proof would rely on establishing congruent triangles within the parallelogram and then using the property that corresponding parts of congruent triangles are congruent to show that the opposite angles are congruent.

HELP!!
Answer: More than 40 students
Step-by-step explanation:
Let x be the number of students .
Given : Mrs. Williams is deciding between two field trips for her class. The Science Center charges $80 plus $5 per student.
i.e. Total cost : [tex]80+5x[/tex] (1)
The Dino Discovery Museum simply charges $7 per student.
i.e. Total cost : [tex]7x[/tex] (2)
The inequality that shows Science Center charge less than the Dino Discovery Museum charges will be :-
[tex]80+5x<7x[/tex]
Subtract 5x on both sides , we get
[tex]80<2x[/tex]
Divide both sides by 2 , we get
[tex]40<x[/tex]
Hence, for more than 40 students the Science Center charge will less than the Dino Discovery Museum charges.

Answer:
C) $1412.79; D) monthly salary of $2995; B) $18.94; C) $573.75
Step-by-step explanation:
Getting paid semimonthly means there will be two paychecks a month. There are 12 months in the year, so this is 24 checks per year. To find the gross pay on each check, divide the salary by 24:
33907/24 = 1412.79
There are 52 weeks per year. This means a weekly salary of 781 would be an annual income of 781(52) = 40,612.
A biweekly salary means getting paid every two weeks. This means there will be 52/2 = 26 paychecks per year; this gives an annual income of 26(1430) = 37,180.
Semimonthly pay means there will be 24 paychecks per year; this gives us an annual income of 24(1550) = 37,200
There are 12 months in the year; this gives us an annual salary of 12(2995) = 35,940. This is the smallest amount in our given choices.
25% = 25/100 = 0.25; this makes the tip 0.25(75.77) = 18.9425 ≈ 18.94.
11.25 per hour for 35 hours is 11.25(35) = 393.75. 4.5% commission is 4.5/100(4000) = 0.045(4000) = 180. Together this gives us
393.75+180 = 573.75

HELP ME PLS!!!!!!!!!!!!!!!!!!!
the number inside the parenthesis includes the interest rate ( annual percentage
looking at the possible functions, if you raise the interest rate to the power of 12, you would need to divide the number of years (t) by 12 as well
so the function could be rewritten as A=1000(1.023^12)^t/12
since the annual percentage rate is 2.3% ( 0.023)
divide 0.023/12*100 = 0.19% per month interest
What are the real and imaginary parts of the complex number?
-6-i
Answer:
Real part: -6
Imaginary part: -1
Step-by-step explanation:
A complex number is a number that has a real part and an imaginary part. These numbers usually are represented in the form a + bi where a and b are real numbers and b is the imaginary part (i is actually the solution to the equation [tex]x^{2} +1=0[/tex] or x²=-1 which has no roots in the real numbers and therefore we call the solution √-1=i)
Now, proceeding to the complex number you wrote, if we write it as a + bi we would have a = -6 b = -1
Therefore the real part is a = -6 and the imaginary part would be -1.
