hello everyone ,
i am having some problems solving this question in maths
Arrange 13.25 kg, 14560 g, 13.6 kg, 12000 g in descending order ,
Write the following decimals as fractions. Reduce the fractions to lowest
form.
a) 3.6 b) 12.5
i hope u also consider explaining
thank you all .
Answer:
Descending order:
14560g
13.6kg
13.25kg
12000g
a.) [tex]\frac{18}{5}[/tex]
b.) [tex]\frac{25}{2}[/tex]
Step-by-step explanation:
To find the difference between kg or g, either divide kg by 100 to convert to g, or multiply g by 1000 to convert to kg.
If we were to put everything into g:
14560g
13600g
13250g
12000g
See how they are still in the correct order?
If we were to put everything into kg:
14.56kg
13.6kg
13.25kg
12kg
Still in descending order!
___________________
Now to find out how to put the decimals into fractions:
Multiply by 10 (since there is only 1 digit behind the decimal, for every digit behind the decimal you multiply by another factor of 10, so if you have 2.55 you multiply by 100)
Following this we get:
36
125
Now divide by the same factor (10), we can't change the value of the number, just the way they look!
[tex]\frac{36}{100}[/tex]
[tex]\frac{125}{10}[/tex]
All that's left is it reduce!
[tex]\frac{18}{5}[/tex]
[tex]\frac{25}{2}[/tex]
And as you can see, we are back to the number I had put in the solution!

Step-by-step explanation:
that the answer I think
6(6v +6) - 5 = 1 + 6v
Need answer with explaination
Answer:
v=-1
Step-by-Step Explanation:
Answer:
[tex]v=-1[/tex]
Step-by-step explanation:
[tex]6\left(6v+6\right)-5=1+6v[/tex]
Use the distributive property to multiply 6 by 6v+6:
[tex]36v+36-5=1+6v[/tex]
Subtract 5 from 36 = 31
[tex]36v+31=1+6v[/tex]
Subtract 6v from both sides:
[tex]36v+31-6v=1[/tex]
Combine like terms:
[tex]36v[/tex] and [tex]-6v[/tex] [tex]=30v[/tex]
[tex]30v+31=1[/tex]
Subtract 31 from both sides:
[tex]30v=-30[/tex]
Divide both sides by 30:
[tex]\cfrac{30v}{30}=\cfrac{-30}{30}[/tex]
[tex]v=-1[/tex]

Step-by-step explanation:
F(x) =2x-1 what is the value of f(x) when x = -1
Answer:
f(x) = -3 when x = -1
Step-by-step explanation:
Let's go through this!
So our equation is f(x) = 2x - 1
we are asked for the value of f(x) when x = -1
Let's consider this, the f(x) value is the y value
and the x value in f(x) is the x value
So when x = -1
what is the y value?
we can use the equation to subsitute -1 into x and solve for f(x)
f(x) = 2(-1)-1
f(x) = -3
Our answer is -3

help me find what 8/9
Answer: B= 8÷9
I found this answer because if you divide 8 and 9 the 8 stays the same and the 9 turns into 1/9 and if you multiply 8 × 1/9 you will get 8/9.
I hope this helps! :)
Hey there!
To find the answer to a fraction to convert it to a decimal you have to DIVIDE to NUMERATOR (the TOP number) from the DENOMINATOR (the BOTTOM number) and it should give you your result to this given question
Option A doesn’t have anything to do with 8/9 because the question isn’t asking what is equivalent to eight divided one-ninths.
Option B. could possibly be your answer because it is asking what is equivalent to 8/9
Option C. also doesn’t have anything to do with 8/9 because the question isn’t asking what it is equivalent to nine divided one-eighths. 9 1/8 =
Option D. as well doesn’t have to do with 8/9 because the equation isn’t 9/8 so you can’t divided 9 from 8
Based on the information we have now. We can answer the question.
Possible answer: Option B. 8 ÷ 9
Good luck on your assignment and enjoy your day!

The two figures are similar. Find the ratios (red to blue) of the perimeters and of the areas. Write the ratios as fractions in simplest form. 6 and 11
Answer:
see explanation
Step-by-step explanation:
The perimeters of the similar figures have the same ratio as the sides.
ratio of perimeters = [tex]\frac{11}{6}[/tex]
ratio of areas = 11² : 6² , that is 121 : 36
ratio of areas = [tex]\frac{121}{36}[/tex]
Select the correct line. Which line is perpendicular to AB
Answer:
line 1
Step-by-step explanation:
perpendicular is the opposite so therefore line 1 is the answer
From the given figure, line AB perpendicular to line 1.
We need to check which line is perpendicular to AB.
What are perpendicular lines?In elementary geometry, two geometric objects are perpendicular if they intersect at a right angle. The condition of perpendicularity may be represented graphically using the perpendicular symbol, ⟂. It can be defined between two lines, between a line and a plane, and between two planes.
From the given figure we can see that line AB perpendicular to line 1.
The line AB perpendicular to line 1, intersect each other and made an angles 90°.
Therefore, from the given figure, line AB perpendicular to line 1.

The ordinate of a point is twice its abscissa . If its distance from the point (4,3) is √10 units ,then the coordinates of the point are ?
Answer:
(1 , 2) and (3 , 6)
Step-by-step explanation:
the point P : (x , y) -> (x , 2x) ... ordinate of P point is twice its abscissa, y = 2x
√10 = √(x-4)² + (2x-3)²
5x² - 20x + 25 = 10
x² - 4x + 3 = 0
(x-1)(x-3) = 0
x = 1 or x = 3
y = 2 or y = 6

Quinn and Logan solved the equation 8(x-5)=8x+40. Quinn said the answer is x=0, Logan said the answer has infinitely many solutions. Who is right? Explain your answer.
Answer:
Neither of them are right
Step-by-step explanation:
First, let's actually solve this equation:
8 ( x - 5 ) = 8x + 40
Distribute on the left:
8 ( x - 5 )
( 8 x X ) + ( 8 x ( -5 ) )
8x - 40
8x - 40 = 8x + 40
Add 40 to each side:
8x = 8x + 80
Subtract 8x from both sides:
0 = 80
0 ≠ 80

Write the equation of the line through
(0, 4) and (2, 0) in slope-intercept form.
Answer: y = -2x + 4
Step-by-step explanation: slope intercept form is "y=mx+b" where m is the slope and b is they y intercept. the y intercept is when x=0 and it's given to us in the question. the y intercept is (0,4). so y=4. we can plug that into the equation to now have y=mx + 4.
now we need to find the slope. we can do this by plugging the two points into the formula [tex]\frac{y2-y1}{x2-x1}[/tex]. so we'd have [tex]\frac{0-4}{2-0}[/tex] to get -4/2 which is -2. -2 is the slope.
so the final answer is y = -2x + 4
