The size of a white tablet is 0.000005 m and that of a red tablet is 0.0000275 m.Find their ratios and Compare their sizes
A ratio will just be trying to find whole number versions of these decimals and then compare them side by side (always divide the larger number by the smaller number).
Therefore:
[tex]\frac{0.0000275}{0.000005}=5.5=\frac{5.5}{1}[/tex]
However, this isn't a proper ratio. Generally, ratios are whole numbers. Since it's 5.5, we can easily make this a whole number by multiplying it by 2. Keep in mind though, what we do to one number we do to the other! So:
[tex]\frac{2}{2}(\frac{5.5}{1})=\frac{2*5.5}{2*1}=\frac{11}{2}[/tex], technically this is a better format since it's whole numbers, but it gives you the ratio (11:2) which is a bit tougher to interpret than (5.5:1)
Therefore, the ratio we'll use is 5.5:1 for simplicity's sake:
From this ratio, we can see that the red tablet is 5.5x the size of the white tablet.
Hope this helps! :)

a teacher is making bags of different colors of modeling clay. the table shows the amount of each color she has avalible. each color will be divided into 3/16 pound bags. how many more bags of purple can she make then yellow?
Using the subtraction operation, the number of purple bags is 3 more than the number of yellow bags.
Amount of each color available :
Amount of purple color = 64 Amount of Yellow bags = 48Amount of color in pound required per bag = [tex]\frac{3}{16} [/tex]Number of Purple bags :
Amount of color required per bag × Amount of purple color
Number of purple bags = [tex]\frac{3}{16} \times 64 = 12[/tex]
Number of Yellow bags :
Amount of color required per bag × Amount of Yellow color
Number of yellow bags = [tex]\frac{3}{16} \times 48 = 9[/tex]
Now we find the difference between the number of Purple and Yellow bags :
Number of purple bags - Number of yellow bags
Difference = 12 - 9 = 3 bags
Therefore, there are 3 more purple bags than Yellow bags.

Find the 98th term of the arithmetic sequence 14, 10, 6,
The required 98th term of the arithmetic progression is -374.
What is arithmetic progression?Arithmetic progression is the series of numbers that have common differences between adjacent values.
Here,
Given sequence,
14, 10, 6,
First term,
a = 14,
common difference d = 10 - 14 = -4
Explicit formula,
nth term = a + (n -1)d
98th term = 14 + (98 - 1)(-4)
98th term = 14 + 97 (-4)
98th term = -374
Thus, the required 98th term of the arithmetic progression is -374.

Determine the slope of this graph. Please get right. And ill add extra points.
Answer:
1/2
Step-by-step explanation:
Slope is the rise over the run. This means the difference in the y values over the difference in the x values.
The two points on the graph are (2,-2) and ( -6, -6 ).
The difference in the y values is a total of 4 units.
The difference in the x values is a total of 8 units.
The slope would then be 4/8 which simplifies to 1/2.
The line slants upward from left to right so the slope is positive.

Describe and correct the error in evaluating the expression. -10^2 = 100
Answer:
-10² = -100
Step-by-step explanation:
The error in the evaluation occurred when the negative base (which is -10) was squared altogether outside of the parenthesis. (-10²) still results in -100.
The only time that the result will produce a positive 100 is when you square -10 this way: (-10)² = 100 because the negative sign is included with the squaring of base through the parenthesis.
Hope this helps.
A power in mathematics is defined as the exponent to which a whole number is raised.
There is no error in evaluating the expression because [tex]-10^{2} = 100[/tex]
When multiplying two negative numbers, their negative signs tend to cancel out
-a x - a = [tex]a^{2}[/tex]
The power for a is given as 2
To solve the above question:
[tex]-10^{2}[/tex]
This can be written as:

The sum of the first 21 terms of the progression, - 18, - 15,-12.....is?
The sum of 21 terms is -1080.
What is Arithmetic Progression?A series in which the differences between each pair of following terms are the same is known as an arithmetic progression.An arithmetic progression is a sequence in which every phrase—aside from the initial term—is created by multiplying the previous term by a predetermined amount.given:
- 18, - 15,-12.....
First term, a= -18
common difference, d= -15 + 18= -3
So, [tex]S_{21[/tex] = 21/2 [ 2(-18)+ (21- 1) (-3)]
[tex]S_{21[/tex] = 21/2 [ -36 + (20) (-3)]
[tex]S_{21[/tex] = 21/2 [ -36 - 60]
[tex]S_{21[/tex] = 21/2 (-96)
[tex]S_{21[/tex] = 21 x (-48)
[tex]S_{21[/tex] = -1008
Hence, the sum of 21 terms is -1080.

Step-by-step explanation:
[tex]\frac{m}{-\frac{6}{5} }[/tex] , is equivalent to
m ÷ - [tex]\frac{6}{5}[/tex] , substitute given value of m
= 6 [tex]\frac{3}{4}[/tex] ÷ - [tex]\frac{6}{5}[/tex] ( change mixed number to improper fraction )
= [tex]\frac{27}{4}[/tex] ÷ - [tex]\frac{6}{5}[/tex] ( leave first fraction, change ÷ to × , flip second fraction )
= [tex]\frac{27}{4}[/tex] × - [tex]\frac{5}{6}[/tex] ( cancel 27 and 6 by 3 )
= [tex]\frac{9}{4}[/tex] × - [tex]\frac{5}{2}[/tex] ( multiply values on numerator/ denominator )
