Answer:
D
Step-by-step explanation:
After dilated by a scale factor of 3 using the origin as the centre the point P(6, 2) become P'(18, 6) option (D) is correct.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have an angle PQR is dilated by a scale factor of 3 using the origin as the centre.
Here the point P is not given, so we are assuming the point P is (6, 2)
After dilated by a scale factor of 3 using the origin as the centre:
P' = (6×3, 2×3)
P' = (18, 6)
Thus, after dilated by a scale factor of 3 using the origin as the centre the point P(6, 2) become P'(18, 6) option (D) is correct.

Malachi’s garden is 2 3/5 meters long. He wants to plant tomato plants every 1/5 of a meter. How many plants can Malachi fit?
Answer:
13 plants.
Step-by-step explanation:
We have been given that Malachi’s garden is 2 3/5 meters long. He wants to plant tomato plants every 1/5 of a meter.
To find the number of tomato plant that will fit the garden, we will divide length of garden by 1/5 as:
[tex]\text{Number of tomato plant that will fit the garden}=2\frac{3}{5}\div \frac{1}{5}[/tex]
Convert mixed fraction into improper fraction:
[tex]2\frac{3}{5}\Rightarrow\frac{2\times5+3}{5}=\frac{10+3}{5}=\frac{13}{5}[/tex]
[tex]\text{Number of tomato plant that will fit the garden}=\frac{13}{5}\div \frac{1}{5}[/tex]
Convert to multiplication problem by flipping the 2nd fraction:
[tex]\text{Number of tomato plant that will fit the garden}=\frac{13}{5}\times \frac{5}{1}[/tex]
[tex]\text{Number of tomato plant that will fit the garden}=\frac{13}{1}\times \frac{1}{1}[/tex]
[tex]\text{Number of tomato plant that will fit the garden}=13[/tex]
Therefore, 13 plants will fit Malachi's garden.
|b|+b^3;b=-2 evaluate the expression
Answer:
-6
Step-by-step explanation:
[tex] | - 2| = 2 \\ {( - 2)}^{3} = ( - 2)( - 2)( - 2) = ( - 8) \\ \\ | - 2 | + {( - 2)}^{3 } = 2 - 8 = - 6[/tex]
To evaluate the expression |b|+b^3 when b=-2, substitute -2 for b, evaluate |b| and b^3 separately and then add the results.
Explanation:To evaluate the expression |b|+b^3 when b=-2, we substitute -2 for b in the expression.
The absolute value of a number is that number's distance from zero on a number line, regardless of which direction. This means that the absolute value of any negative number is its positive equivalent. Thus, |b| is the same as |-2|, which equals 2.
Secondly, b^3 means b multiplied by itself twice. So (-2)^3 equals -2*-2*-2 which is -8.
First, we evaluate |b|. The absolute value of -2 is 2, so |b| = 2.
Next, we evaluate b^3. (-2)^3 = -8.
Finally, we add the two results together: 2 + (-8) = -6.
Therefore, when b=-2, the expression |b|+b^3 evaluates to -6.

what is
[tex] \sqrt{180 } [/tex]
simplified?
Answer:
Step-by-step explanation:
I don't know exactly how simplified it will be, but you can get the square root smaller.
180: 2*2 * 3*3 *5
For every pair of prime factors you can take 1 of the pair outside the the square root and throw the other one away
sqrt(2*2*3*3*5) = 2 * 3 * sqrt(5) = 6*sqrt(5)
Liam bought a comic book and had $5 left. If he had a total of $8 walking into the store, how much did he spend on the comic book?
Liam used the equation 5x=8 to model the problem. He said that x represents the amount of money he spent. Liam said that the solution, x=1.6, means that he spent $1.60. Is he correct? Why or why not? If he is incorrect find the correct answer showing your work.
Pls Help Me
Answer: The comic book was $3.
Step-by-step explanation:
Instead of 5x=8, it should have been 5+x=8 because he only purchased a single comic book. Subtract 5 from 8 and your X value is 3.
Answer:
Liam spent $3 on the book.
Step-by-step explanation:
Liam bought a comic book and had $5 left.
He had a total of $8 walking into the store, so he spent [tex]8-5=3[/tex] dollars on the comic book.
Liam used the equation 5x=8 to model the problem.
This is wrong. The correct form would have been [tex]8-x=5[/tex] or [tex]5+x=8[/tex] where x represents the amount of money he spent.
Hence, Liam spent $3 on the book.

|2x-4|=22
Answer:
2x-4 = 22
2x = 26
x=13 check |26-4|=22
-(2x-4) = 22
-2x+4 = 22
-2x = 18
x=-9 Check |-18 -4| = |-22| = 22
Answer:
x=13
Step-by-step explanation:
Finding the answer to this is very simple actually. you can actually solve this problem without the || because x has to be a positive value for this to work. 2x-4=22 can be done by adding 4 to both sides and getting the answer 26. Isolate the variable by dividing both sides by 2 to get x=13
Let's assume that bacteria doubles every 10 minutes. If a culture begins with exactly
30 bacterial cells, how many bacteria will be present after 1 hour?
A 960 Bacteria
B 1000 Bacteria
C 1520 Bacteria
D 1920 Bacteria
Greetings!
First off, we should know that there are 60 minutes in an hour. Therefore, the first step we will need to do, is divide 60 by 10.
60 ÷ 10 = 6
As shown above, we now know we will have to double the number 6 times. If we start with 30, this will be our first problem.
(1) 30 + 30 = 60
And so on and so forth...
(2) 60 + 60 = 120
(3) 120 + 120 = 240
(4) 240 + 240 = 480
(5) 480 + 480 = 960
(6) 960 + 960 = 1920
And after our sixth time we have our answer:
1920 bacteria

A line is parallel to y = 3x - 12 and
intersects the point (1, -2). What is the
equation of this parallel line?
Answer:
y=3x-5
Step-by-step explanation:
parallel means that both lines share the same gradient.
from the equation y=3x-12 , we can deduce that the gradient is 3 because it is in the gradient-intercept form
now substitute values into formula
y-y1=m (x-x1)
y--2=3 (x-1)
expand brackets and simplify
y+2=3x-3
subtract 2 from both sides of equation
y=3x-5
A farmer plans to use 180 feet of fencing to enclose a rectangular region, using part of a straight river bank instead of fencing as one side of the rectangle, as shown in the figure.
The farmer can determine the dimensions of the fenced area by solving the formula L + 2W = 180 feet, where L is the length of the fenced region along the river bank and W is the width.
Explanation:This is a classic application of the perimeter of a rectangle in the field of Mathematics. If the farmer is using part of a straight river bank instead of fencing for one side of the rectangle, then he only needs fencing for the other three sides. The formula to calculate the perimeter of a rectangle is 2(length) + 2(width), but since one side is not fenced, it is length + 2(width) in this case.
If we assume the length (L - along the river bank) and width (W) of the rectangular area, then the equation can be expressed as:
L + 2W = 180 feet
This formula can help the farmer calculate the dimensions of the fenced area needed in order to use his materials most effectively. He needs to solve this equation to find the values of length and width that add up to 180 feet.

What is 14/18 as decimal
Answer:
14/18 = 0.778
Step-by-step explanation:
14 divided by 2 = 7
18 divided by 2 = 9
7/9 is the same as 7 divided by 9
= 0.778
The decimal equivalent of [tex]\( \frac{14}{18} \)[/tex] is approximately 0.777777777777778.
To convert [tex]\( \frac{14}{18} \)[/tex] to a decimal, one divides 14 by 18. This can be done by hand or with a calculator. When dividing 14 by 18, the result is a repeating decimal where the digit 7 repeats indefinitely.
