Answer:
[tex]\frac{131}{99}[/tex]
Step-by-step explanation:
Let
[tex]x=1.323232...[/tex]
Multiply x by a power of [tex]10[/tex], one that keeps the decimal part of the number the same:
[tex]100x=132.3232..[/tex]
Subtract [tex]x[/tex] from [tex]\\100x[/tex]
[tex]100x-x=132.3232...-1.3232...=131[/tex]
The repeating decimals should cancel out
[tex]\\99x=131[/tex]
solve for x
Divide by [tex]99[/tex] both sides
[tex]x=\frac{131}{99}[/tex]
What is the surface area of the regular pyramid given below?
Answer: the answer is 189 units^2
Step-by-step explanation: Apex
The surface area of the given regular pyramid is 140 units^2, calculated using the formula Surface Area = B + 1/2Pl, where B is the base area, P is the perimeter of the base, and l is the slant height.
The surface area of a regular pyramid is calculated by adding the area of the base to the total area of the triangular faces.
The formula to calculate this is: Surface Area = B + 1/2Pl, where B is the base area, P is the perimeter of the base, and l is the slant height.
Given the dimensions, 10cm is base and 7cm as a slant height, we can calculate that the base area (B) is 100 cm2 and the perimeter (P) is 40 cm.
Plugging these values into the surface area formula, we find that the surface area is 140 cm2 (100 cm2 for the base and 140 cm2 for the triangular faces).
Therefore, the correct answer is B. 140 units2.

The triangles are isosceles and ABC:JKL what is the length of JL
the quotient of 100 and the sum of b and 24
To find the quotient of 100 and the sum of b and 24, divide 100 by the sum of b and 24.
Explanation:The quotient of 100 and the sum of b and 24 can be found by dividing 100 by the sum of b and 24. This can be expressed as:
Quotient = 100 / (b + 24)
For example, if b is 5, the sum of b and 24 is 29. So, the quotient of 100 and 29 would be approximately 3.4483.

Answer:
615.6
Step-by-step explanation:
First find the number of cubic feet.
V = B * h
B is a triangle with a right angle on your left and two 6 foot lengths on each leg.
Area = 1/2 b * h
b = 6 feet
h = 6 feet
Area = 1/2 * 6 * 6 = 18 square feet.
The volume = B * h
h = 11.4
B = 18 sq ft
Volume = 18 * 11.4
Volume = 205.2 Cubic Feet.
Each cubic foot costs 3.00 dollars
Cost = volume * cost/cu foot
Cost = 205.2 * 3
Cost = 615.6

Answer:
$20,160
Step-by-step explanation:
They don't have a year to pay it back. They have four months so you just use that as time.
Write the equation
A = 15,000 x (1 + 0.086 x 4)
( ) first.
0.086 x 4 = 0.344
rewrite.
A = 15,000 x (1 + 0.344)
( ) again.
1 + 0.344 = 1.344
rewrite
15,000 x 1.344 = 20,160

The student made a calculation error in converting 4 months into a year fraction. It should be 0.333..., not 0.33. With the correct conversion, the maturity value can be accurately calculated using the formula A=P(1+RT).
Explanation:
From the details that you've given, the student used the formula A=P(1+RT) correctly, where A is the maturity value of the loan, P stands for the principal amount, R for the rate of interest, and T for time.
In this question, P = $15000, R = 8.6%, and T = 4 months. The student correctly changed 8.6% to 0.086 (since percentage must be converted to decimal form by dividing by 100 in calculations) and also accurately converted 4 months into 0.33 (since the term of the loan is expressed in terms of a year).
However, the correct conversion of 4 months into year should be 4/12 = 0.333.... (since 1 year is equal to 12 months), not 0.33. So T = 0.333...
Let's plug in these values:
A = 15000(1+0.086*0.333...)
This will give you the accurate maturity value.

Deanna's scores for a computer game are 18, 20, 22, 25, 12, and 20. Lilly's scores are 20, 20, 21, 21, 16, and 16. Who has the higher mean score? By how much?
Answer: Deanna has the higher mean score by .5
Step-by-step explanation: The important piece of information to remember here is that the mean is the average. In order to solve the question, the first thing that you need to do is calculate the average of each of their scores.
Deanna = 18+20+22+25+12+20 = 117
The mean = 117/6 = 19.5
Lilly = 20+20+21+21+16+16 = 114
The mean - 114/6 = 19
how to simplify |x + 120| when x < -120
Start with definition of absolute value, |x|.
It says,
|x| = x, for any x >= 0 and
|x| = -x, for any x < 0
Now, instead of x, we have the expression x+120 inside the absolute value brackets:
|x+120|
Play the same game as above - what is the absolute value here?
|x+120| = x+120 for (x+120)>=0 and
|x+120| = -(x+120) for (x+120)<0
Now, recognize that the last condition (x+120)<0 is the same as writing x<-120. That is the condition in the question. Therefore the absolute value |x+120| will equal the second expression (for that condition), namely -(x+120), or -x-120.
To simplify |x + 120| when x is less than -120, you change the sign of the expression inside the absolute value to get the simplified form as -x - 120.
To simplify |x + 120| when x < -120, we need to consider the definition of absolute value. The absolute value of a number is the non-negative value of that number without regard to its sign. Since x is less than -120, x + 120 is a negative number, and to find its absolute value, we change the sign to positive.
Therefore, the simplification of |x + 120| when x < -120 is simply -(x + 120), which equals -x - 120.

Solve the equation above 2x+18=7x-30
Answer:
9.6
Step-by-step explanation:
✯Hello✯
↪ so first we need to 'kill' the smaller x. This can be done by taking 2x from 7x
↪ That leaves us with 18= 5x-30. Add 30 on both sides and we get 48=5x
↪ we divide by 5 on both sides
↪ that gives us 9.6
HOPE THIS HELPS
❤Gianna❤
To solve the equation 2x+18=7x-30, subtract 2x from both sides, add 30 to both sides, and divide both sides by 5 to find x = 9.
Explanation:To solve the equation 2x+18=7x-30, we need to isolate the variable x on one side of the equation. First, we can start by simplifying both sides of the equation. Subtracting 2x from both sides gives us 18 = 5x - 30. Next, we can add 30 to both sides to get rid of the -30 on the right side. This gives us 48 = 5x. Finally, divide both sides by 5 to solve for x. The final solution is x = 9.

1) Rewrite the expression without using absolute value |2x−8| , if x<4
Answer:
8 - 2x
Step-by-step explanation:
|2x -8| , x < 4
Two conditions:
(a) |2x - 8| = (2x - 8) if (2x - 8) ≥ 0
(b) |2x - 8| = -(2x - 8) if (2x - 8) < 0
If x < 4, (2x - 8) <0, so condition (b) applies.
|2x - 8| = -(2x - 8) or
|2x - 8| = 8 - 2x
The equivalent expression is 8 - 2x.

EXPLANATION
The given limit is
[tex] lim_{x \to \: 0}( {x}^{2} - 1) [/tex]
To evaluate this limit by direct substitution,
We put x=0 in the function.
This implies that that ,
[tex] lim_{x \to \: 0}( {x}^{2} - 1) = {0}^{2} - 1[/tex]
This simplifies to,
[tex] lim_{x \to \: 0}( {x}^{2} - 1) = 0 - 1[/tex]

Answer:
the art teacher still needs 68 sticks of clay
Step-by-step explanation:
9*10=90
6*7=42
90+42=132
200-132=68 please can you answer my newest question im so stuck
The teacher needs 74 more sticks of clay which can be bought in 7 large boxes. The total cost for these boxes is $98.
Let's solve this step by step:
Step 1: Calculate the total number of clay sticks provided by the donated boxes.
Assuming each small box contains 6 sticks of clay and each large box contains 12 sticks of clay (these are reasonable assumptions for this problem).The art shop donates 9 small boxes and 6 large boxes.Total from small boxes: 9 boxes * 6 sticks = 54 sticksTotal from large boxes: 6 boxes * 12 sticks = 72 sticksTotal donated sticks: 54 + 72 = 126 sticksStep 2: Calculate the number of additional sticks needed.
Total sticks needed: 200 sticksAlready donated: 126 sticksAdditional sticks needed: 200 - 126 = 74 sticksStep 3: Calculate the number of large boxes needed to obtain the additional 74 sticks.
Each large box contains 12 sticks.Number of large boxes required: 74 sticks / 12 sticks per box = 6.1667Since the teacher needs whole boxes, round up to the next whole number: 7 large boxesStep 4: Calculate the total cost of the boxes.
Cost per large box: $14Total cost: 7 boxes * $14 = $98Therefore, the total cost for the additional 7 large boxes of clay is $98.
An office supply store carriers a all-in-one printer with a regular price of $240. The printer is on sale at 15% off. In addition, the store is offering a $20 mail-in rebate. How much will it cost a customer to purchase this printer, including 5% sales tax on the in-store purchase price?
Answer:
Price of the printer is = $193.20
Step-by-step explanation:
Office supply store purchased an all in one printer wit a regular price = $240
After 15% off price of the printer = $240 - 15% of $240
= [tex]240-\frac{15\times 240}{100}[/tex]
= 240 - 36
= $204
The store is offering $20 mail in rebate so the price of printer after rebate
= $204 - $20
= $184
Now price of the printer including sales tax = 184 + 5% of 184
= 184 + [tex]\frac{5\times 184}{100}[/tex]
= 184 + 9.20
= $193.20
