30 inches to 24 inches..
PLZ EXPLAIN !! :)
Answer:
20% decrease
Step-by-step explanation:
step one- subtract
30-24=6
step 2 is divide
amount of change from step one÷beginning val
6/30=.2
convert to %
.2=20%
it is a decrease as the value 30 went down to 24

The scale of dilation is the number that you multiply one side of the original triangle to get its corresponding side on the new triangle. In this case, it can be seen that AB corresponds to A'B', and so you divide A'B' by AB (6 divided by 4) to find that the scale factor is 6/4, or 3/2. If you do this with any of the other sides you will get the same answer.
Answer:
If you do this with any of the other sides you will get the same answer.
Step-by-step explanation:
6/4
A'B' by AB
6/4 or 3/2.

Answer:
(1,-8), (-6,-4), (3,7), (-6,1)
Step-by-step explanation:
In a function the x values cannot repeat. Look at each answer choice and see if an x repeats:
The first choice (top left) has the x value, -6, repeating. It cannot be a function.
The second choice (top right) does not have an x value repeat. This makes it a function!
The third choice, (bottom left) does not have an x value repeat. This makes it a function!
The fourth choice, (bottom right) does not have an x value repeat. This makes it a function!
I really need help with the last one if you could help it would be awesome! Tysm.
it’s the second one..................
pls help me out on this!
Answer:
[tex]=-1\frac{5}{9}[/tex]
Step-by-step explanation:
We want to write:
[tex]-1.\bar{5}[/tex]
As a mixed number in the simplest form.
We can use the following algebraic trick. First, we can ignore the negative and add it on the very end. So, we have the number:
[tex]1.55555...[/tex]
Let's let this equal to n. So:
[tex]1.55555...=n[/tex]
Now, we will multiply n by 10^x for the number of repeating digits x.
There is only one digit repeating (the 5). So, we will multiply both sides by 10^1 or just 10. This yields:
[tex]15.55555...=10n[/tex]
Now, we will subtract n from both sides. This yields:
[tex]15.5555...-n=10n-n[/tex]
On the right, we will just get 9n.
However, let's replace n with 1.5555... on the left. This yields:
[tex]15.5555...-1.5555...=9n[/tex]
All of the repeatings 5s will cancel. 15-1 is 14. So:
[tex]14=9n[/tex]
Now, divide both sides by 9. So, our n is:
[tex]n=\frac{14}{9}[/tex]
And since we originally set n to be 1.5 repeating, this is equivalent to:
[tex]n=1.\bar{5}=\frac{14}{9}[/tex]
And now, we can add back the negative:
[tex]-1.\bar{5}=-\frac{14}{9}[/tex]
We can rewrite this as:
[tex]=-(\frac{9}{9}+\frac{5}{9})[/tex]
So, as a mixed fraction, our decimal is:
[tex]=-1\frac{5}{9}[/tex]
And we're done!

Answer:
$3.00; $7.29
Step-by-step explanation:
Find what 8% of $37.50 is:
x/37.50 = 8/100
cross multiply
x × 100 = 37.50 × 8
100x = 300
divide both sides by 100
x = 3
$3 is 8% of $37.50
If 8% was added to the bill, then add $3 to $37.50
3.00 + 37.50 = 40.50
Now find what 18% of 40.50 is
x/40.50 = 18/100
cross multiply
x × 100 = 40.50 × 18
100x = 729
divide both sides by 100
x = 7.29
$7.29 is 18% of the bill after sales tax
They tipped $7.29

What is required of a proportional relationship that is not required of a general line relationship?
Answer:
Step-by-step explanation:
Pertains to y-intercept is then 0.
It introduces the relationship between two variables and is called correlation. Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)

Aggie is an australian exchange sudent in china, and she currenly has 14,000 yuan in her bank account. If the exchange rate changes from 1 australian dollar to 6.21 yuan to 1 australian dollar 6.37 chinese yuan, what happens to the value in australian dollars of the money in aggies bank account
Step-by-step explanation:
Amount in Aggie bank account = 14,000 yuan
Initial exchange rate:
1 Australian dollar = 6.21 yuan
Initial amount in Australian dollars will be;
x aus dollar = 14,000 yuan
cross multiply
6.21x = 14,000
x = 14,000/6.21
x = 2,254.428 australian dollars
If the exchange rate increases to 6.37 Chinese yuan, her new balance in Australian dollars will be y;
1 Australian dollar = 6.37 yuan
y Australian dollar = 14,000 yuan
cross multiply
6.37y = 14,000
x = 14,000/6.37
y = 2,197.80 Australian dollars
The change in her account balance due to increase in exchange rate is y-x
y-x = 2,197.80 - 2,254.428
y-x = -56.626 aus dollars
This negative values shows a decrease in her account balance by 56.626 aus dollars due to increase in the exchange rate.
Please help . Thank you :)

How many gallons of 25% alcohol solution and 40% alcohol solution must be mixed to get 6 gallons of 30%
alcohol solution?
Answer:
amt of 25% solution to mix=6 gal
amt of 40% solution to mix=3 gal
Step-by-step explanation:
let x=amt of 25% solution to mix
9-x=amt of 40% solution to mix
25%x+40%(9-x)=30%*9
.25x+3.6-.40x=2.7
