Can someone please help me ASAP

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

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!

Step-by-step explanation:

i learn this back in 8 and 9 grade trust me also can u put me Brainliest

if am right

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.

then do £59-£5.90=£53.10

Answer:

A.) 53°

Step-by-step explanation:

SPR + RPQ =90°

37° + RPQ = 90°

37° - 37° + RPQ = 90° - 37°

RPQ = 53°

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

.15x=0.90

x=6

9-x=3

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)

it’s the second one..................

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.
