80% of 90 is the same as 8/9 of 90. true or false
20% of 90 is the same as 1/5 of 90. true or false
Answer:
Both true
Step-by-step explanation: 80%*90=72. 72/90=8/9.
20%*90=18. 18/90=1/5
80% of 90 is the same as 8/9 of 90 is false.
20% of 90 is the same as 1/5 of 90 is true.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, 80% of 90 is the same as 8/9 of 90.
80% of 90 is,
= (80/100)×90.
= 8×9.
= 72.
And,
(8/9)×90.
= 8×10.
= 80.
So, 80% of 90 and 8/9 of 90 is not the same.
20% of 90 is the same as 1/5 of 90.
(20/100)×90.
= 2×9.
= 18.
And,
(1/5)×90.
= 18.
So, 20% of 90 is the same as 1/5 of 90.

On a number line, the coordinates of j, k, l, m, n are −10.5, −4, −1, 1.5, 4 respectively. Find the lengths of the two segments. Are they congruent? Jl¯¯¯¯¯¯ and kn ¯¯¯¯¯¯¯
Answer and Step-by-step explanation: A Line Segment is a part of a line with two endpoints and fixed length.
The length of segment JL is
JL = [tex]-1-(-10.5)[/tex]
JL = 9.5 units
And of KN:
KN = [tex]4-(-4)[/tex]
KN = 8 units
The term congruent refers to an object, form or figure that have the same shape and size.
Both segments have the same shape (a line), however not the same size. So, segments JL and KN are not congruent.

The lengths of DF and HI
Step-by-step explanation:
SSS
This means Side Side Side
So to prove this triangle is similar we have to use only true information about the sides.
We can already cross off the second and last answer choices because they are talking about angles.
The first answer choice is about the sides but first we have to determine if its true or not.
Side DF is on the left opposite of angle G
HI is also on the left, opposite of angle I
We can assume those sides are the same but to really know we can check if the other sides match up
We know this constriction has a scale factor of: 1.66666667
If you divide 3.5 by our scale factor you get 2.1
If you divide 5 by our scale factor you get 3
This proves that DG and HJ and FG and IJ would be the matching constricted side
This means that DF and HI would be matching as well making the first answer choice correct.

-2x+y=-8 and 4x-6y=-24 I need help :(
Answer: 2x+y=-8 = x=-1/2y-4
4x-6y=-24 = x =3/2y-6
Step-by-step explanation:
2x+y=-8 -- Step 1: Add -y to both sides.
2x+y+−y=−8+−y
2x=−y−8
Step 2: Divide both sides by 2.
2x/2=-y-8/2
4x-6y=-24 -- Step 1: Add 6y to both sides.
4x−6y+6y=−24+6y
4x=6y−24
Step 2: Divide both sides by 4.
4x/4=6y-24/4

Answer:
One bottle of soap will hold 3/8
Step-by-step explanation:
3/4= The amount of soap she has in total
3/4= 6/8 which is the same amount but now we can divide it by 2
.75 (6/8) divided by 2= .375 (3/8)
So each soap dispenser will have 3.75 liters of soap.
Sentences: To check our work
.375x2= .75
3/4 divided by 2= 3.75

b. increase operational capital with a bank loan
c. lower fixed expenses (phone, electric, advertising)
d. lower direct costs (labor, purchasing, controlling, inventory)
Answer:
b
Step-by-step explanation:
increase operational capital with a bank loan
Increase operational capital with a bank loan is not a recommendation the author of the Businesstown.com article makes to lower your break-even point.
What are Expenses?An expense is an item requiring an outflow of money, or any form of fortune in general, to another person or group as payment for an item, service, or other category of costs.
In the article from BusinessTown.com, the author recommends several strategies to lower the break-even point of a business, which is the point where total revenue equals total expenses. The lower the break-even point, the easier it is for a business to make a profit.
Increase operational capital with a bank loan is not a recommendation to lower the break-even point.
Instead, it suggests borrowing more money to finance operations, which can increase the break-even point and the amount of revenue needed to cover expenses.
Hence, increase operational capital with a bank loan is not a recommendation the author of the Businesstown.com article makes to lower your break-even point.

f(x)/g(x)
(x2-1)/(x-1)
x cannot equal 1 because this would render the denominator, also known as the divisor, as zero.
x can be greater than 1.
If you would like, we can factor the numerator...
x2-1
(x+1)(x-1)
FIRST...(x)(x)=x2
OUTER...(x)(-1)=-1x=-x
INNER...(1)(x)=1x=x
LAST...(1)(-1)=-1
x2-x+x-1
x2-1
So...
f(x)/g(x)=[(x+1)(x-1)]/(x-1)
(x-1) is in the numerator and denominator. It cancels...
f(x)/g(x)=(x+1)

Answer:
It loses -0.04 milliliters per minute.
Step-by-step explanation:
The pipe loses 1 1/5 milliliters (I'mma just call it ml from now on) every 30 minutes. The question is asking how many ml it loses every one minute. To find this, divide 1 1/5 ml by 30. This is very difficult with fractions tho, so convert the fraction into a decimal. (1 1/5 as a decimal is 1.2) Then divide 1.2 by 30 and you get -0.04 ml per minute.
Make sure you put that it loses *negative* 0.04 ml per minute!

What value of v makes the
equation true?
5(5 + 5v) =-29 + 7v
Answer:
v = -3
Step-by-step explanation:
5 (5 + 5v) = -29 + 7v
or, 25 + 25 v = -29 + 7v
or, 25 + 29 = 7v - 25 v
or, 54 = - 18v
or, v = -54/18
or, v = -3
for checking ( putting the value of v in both sides )
5( 5 + 5 (-3))= -29 + 7 (-3)
or, 5 ( 5 - 15 ) = -29 -21
or, 5 (-10) = -50
or, -50 = - 50
the equation is true
hope it will help you ☺✌
Answer:
v = - 3
Step-by-step explanation:
Given
5(5 + 5v) = - 29 + 7v ← distribute parenthesis on left side
25 + 25v = - 29 + 7v ( subtract 7v from both sides )
25 + 18v = - 29 ( subtract 25 from both sides )
18v = - 54 ( divide both sides by 18 )
v = - 3
