55.5% repeating as a decimal
Answer:
55.5 ÷ 100 = 0.555
Step-by-step explanation:
When you ask, "What is 55.5 as a decimal?", we assume you want to know what 55.5 percent is as a decimal. In other words, 55.5 percent converted to decimal.
First, we will tell you why it is useful to know 55.5 as a decimal.
Normally, to calculate 55.5 percent, you would multiply a number by 55.5 percent and then you would take the product of that and divide it by 100 to get the answer.
Instead, you can simply multiply a number by 55.5 as a decimal to get the answer.
55.5 percent means 55.5 per hundred. Therefore, to get 55.5 as a decimal, all you have to do is divide 55.5 by 100 like so:
55.5 ÷ 100 = 0.555
Answer:
55.5% = 0.555
Step-by-step explanation:
55.5% = 55.5/100 = 0.555
question : 4(3x + 2) -6 x 6
Answer:
x= 24
Step-by-step explanation:
open the bracket
4×3x =12x + 4 × 2 =8
12×+ 8-6×6
12×+ 12
x= 24
Answer:
12x - 28
Step-by-step explanation:
Because of PEMDAS you start with the parentheses and distribute the 4.
So,
(12x + 8) -6 x 6
Then, solve for the 6's
(12x + 8) -36
Remove the parentheses
12x + 8 - 36
Lastly, you get
12x - 28.
This is as far as you can go because there is no equals sign so you cannot actually solve for x.

Answer:
T = 0.01925 m
Step-by-step explanation:
It is given that,
Thickness of a piece of a paper is [tex]5.5\times 10^{-4}\ m[/tex]
Total number of pieces are 35
We need to find the thickness of the whole stack. It is simply a case of unitary method.
For 35 pieces, thickness is :
[tex]T=35\times 5.5\times 10^{-4}\\\\T=0.01925\ m[/tex]
So, the thickness of the whole stack is 0.01925 metres.
T. For a science experiment, Katie had
to cool one sample bacteria to -52°C.
She had to cool a second sample
bacterium to -79°C. What is the
difference in the two temperatures?
Please help me figure out the equation too.
Answer:
Step-by-step explanation:
A "difference" indicates subtraction is being used. The difference between these 2 numbers is found the same way we find the distance between 2 points on a number line. Since both the difference and the distance have to be positive numbers, the formula to find it is
|a - b| which is the absolute value of a - b.
If a = -52 and b = -79:
| -52 - (-79) | = | -52 + 79 | = 27 OR
If a = -79 and b = -52:
| -79 - (-52) | = | -79 + 52 | = | -27 | = 27

-2x² - 4x + 5 = 2x² + 4x + 5
4x² + 8x = 0
factor out 4x
4x(x + 2) = 0
divide both sides by 4x

The standard normal curve shown below models the population distribution of a random variable. What proportion of the values in the population does not lie between the two z-scores indicated on the diagram? z = -1.2 z = 0.85
Answer:
31.28%
Step-by-step explanation:
The z score is used in statistics to determine by how many standard deviations the raw score is above or below the mean. If the raw score is above the mean then the z score is positive while if the raw score is below the mean then the z score is negative. It is given by:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
Given the z score z = -1.2 z = 0.85. From the normally distribution table, the probability that a value falls between z = -1.2 and z = 0.85 = P(z < 0.85) - P(z < -1.2) = 0.8023 - 0.1151 = 0.6872
The proportion of values that do not fall between z = -1.2 and z = 0.85 = 1 - 0.6872 = 0.3128 = 31.28%

Answer:
1×10⁻⁴ and 9.8×10⁵Step-by-step explanation:
The standard form of writing a scientific notation is expressed as [tex]a.b*10^n[/tex] where a, b and n are integers. Note that a, b and n cannot be a fraction. When writing in scientific notation, the value of 'a' must not be equal to zero and it must not be a 'two digits values' but just 'a digit value'.
Based on the above conclusion, the following numbers are correctly written in scientific notation.
1×10⁻⁴ and 9.8×10⁵
- The expression 10.8×10 −3 is not correctly written because the value of a on comparison is a two digits number i.e 10.
- Also, 0.54×10^6 is not correctly written because a is zero on comparison
- 7.6×10 2.5 is not correctly written because the power is a decimal number i.e 2.5. We must only have an integer as the degree.

Question. 7 Let abc be a three-digit number. Then, abc + bca + cab is not divisible by (a) a + b + c (b) 3 (c) 37 (d) 9
Answer:
D. 9
Step-by-step explanation:
Let
abc=100a+10b+c
bca=100b+10c+a
cab=100c+10a+b
abc + bca + cab=(100a+10b+c) + (100b+10c+a) + (100c+10a+b)
=100a + 10b + c + 100b + 10c + a + 100c + 10a + b
Collect like terms
=100a + a + 10a + 10b + 100b + b + c + 10c + 100c
=111a + 111b + 111 c
Factorise
=111(a+b+c)
abc + bca + cab = 111(a+b+c)
Factors of 111(a+b+c)= 1, 3, 37, 111, and (a+b+c)
abc + bca + cab is divisible by a+b+c because it is a factor of 111(a+b+c)
abc + bca + cab is divisible by 3 because 3 is a factor of 111(a+b+c)
abc + bca + cab is divisible by 37 because 37 is a factor of 111(a+b+c)
abc + bca + cab is not divisible by 9 because 9 is not a factor of 111(a+b+c)

point ₂ ( 3 , 3 ). x₂ = 3 , y₂= 3
Now, let's find the slope:
Slope ( m ) = [tex] = \frac{y2 - y1}{x2 - x1} [/tex]
[tex] = \frac{3 - ( - 1)}{3 - ( - 3)} [/tex]
[tex] = \frac{3 + 1}{3 + 3} [/tex]
[tex] = \frac{4}{6} [/tex]
[tex] = \frac{2}{3} [/tex]
At ( 3 , - 1 )
y = mx + c , where m is the gradient / slope amd c is called the intercept on y-axis
[tex] - 1 = \frac{2}{3} \times ( - 3) + c[/tex]
Solve for c
[tex] - 1 + 2 = c[/tex]
[tex]c = 1[/tex]
Since, The red line is dotted line. Therefore it does not include the equal to part. And the shaded region is upper part. Hence, ' > ' should be used.
The answer would be:
[tex]y > \frac{2}{3} x + 1[/tex]

81cm squared
Step-by-step explanation:
Area for triangle:
base x height x 1/2 =
5cm x 6cm x 1/2 =
30cm/2 = 15cm squared
Area for rectangle:
length x width:
11cm x 6cm = 66cm squared
Add the totals together = 66cm + 15cm = 81cm squared
Answer:
(triangle)
A. A= b × h ÷ 2
= 5cm × 7cm ÷ 2
= 35cm ÷ 2
= 17.5cm²
(rectangle)
B. A= L × W
= 11cm × 6cm
= 66cm²
(total of both area)
Total = A+B
=17.5cm² + 66cm²
=83.5cm²
Step-by-step explanation:
To find the area of a triangle, you must do the following formula:
Area= base × height ÷ 2
=x²
To find the are of the rectangle, you must do the following formula:
Area= Length × Width
= x²
Then you add the are of the first shape, A, with the second shape, B.
Total= A + B
=x²

Find the mean, median, and mode
Answer:
Mean = $70.8
Median = $70
Mode = $60
Step-by-step explanation:
From the line plot attached,
Prices of the sunglasses are,
$20, $20, $50, $50, $50, $60, $60, $60, $60, $60, $60, $70, $70, $70, $80, $80, $80, $80, $90, $90, $90, $90, $100, $100, $130
Since mean of the data = Average of the terms
[tex]=\frac{\text{Sum of the terms in the data set}}{\text{Number of terms}}[/tex]
= [tex]\frac{2(20)+3(50)+6(60)+3(70)+4(80)+4(90)+2(100)+130}{(2+3+6+3+4+2+1)}[/tex]
= [tex]\frac{40+150+360+210+320+360+200+130}{25}[/tex]
= [tex]\frac{1770}{25}[/tex]
= $70.8
Median = Middle term of the data set
Since number of terms of the data set are odd (25)
Therefore, median = [tex](\frac{n+1}{2})\text{th term}[/tex] [where n = number of terms in the data set]
= [tex]\frac{25+1}{2}[/tex]
= 13th term
13th term of the data set is $70.
Therefore, Median = $70
Mode = Term repeated the most
In the data set $60 is the term which is repeated the most (6 times).
Therefore, Mode = $60
An apartment complex has several 9-story buildings, and every apartment in the complex has a unique number. On the first floor of one of the buildings, you see four apartments numbered 109, 110, 111, and 112. In which building and on which floor is apartment 207?
Answer:
The apartment with the number 207 is in the second floor of the building that comes before the building with apartments numbered 109, 110, 111, and 112
Step-by-step explanation:
The given information of the naming of the apartments are;
The four apartments on the first floor of the building were numbered, 109, 110, 111, and 112
Therefore;
The first digit number, 1, which is consistent, represent the floor number (first floor)
The buildings in the complex are 9-story buildings, with 9 × 4 = 36 Apartments each
Therefore, for the numbers of the apartment to be from 9 to 12, on the floor, the numbering of the apartments is sideways such that the numbers of the apartment in the given building will be X09, X10, X11, and X12, where X is the floor number
The previous building apartment will be numbered X05, X06, X07, X08
Therefore, the apartment with the number 207 is in the second floor of the previous building to the one given.
Answer:
Apartment 207 is in 7th floor of the building number 6 .
Step-by-step explanation:
Given:
There are 9 floors in the building
The number of building and floor of apartment 207 .
Each floor in the building has four apartments
The number of apartment in a building = 4 * 9 = 36
Numbers on each floors are 01 to 36 after floor number
first floor of one of the buildings, we have four apartments numbered 109, 110, 111, and 112.
From the numbers, 1 is representing the floor number
9 , 10 , 11 & 12 are representing four apartments number
Recall,
Each floor has 4 apartments
207 = 36 * 5 + 4 * 6 + 3
36 * 5 = 5 buildings
4 * 6 = 6 floor of 6th building
180+24=204
205 - 208 =6th building 7th floor
Apartment 207 is in 7th floor of the building number 6 .
