18.5% as a decimal is 0.185
0.186×3200= 592
3,200-592= $2,608

Consider the two triangles. Triangles A B C and H G I are shown. Angles A C B and H I G are right angles. The length of side A C

zheka24 [161]

Answer:

Both are similar by SAS similarity.

This SAS similarity is equivalent to the congruence.

Step-by-step explanation:

Step 1:

To prove that ACB and HIG as similar triangles.

We have to look upon the corresponding sides.

SAS= Side angle sides , there the angle must be in between two sides.

$\angle$ ACB = $\angle$ HIG

Lets work on the corresponding sides.

IG/AC = IH/AC

$\frac{9}{15}$ = $\frac{12}{20}$

Reducing each to lowest form, we divide numerator and denominator by 3 for the 1st fraction and by 4 for the 2nd fraction.

We have

$\frac{3}{5}$ = $\frac{3}{5}$

Both sides are equal.

So its proved that both are similar with SAS similarity theorem.

if A and B together can do a piece of work in 10 days and B along can do it in 15 days, how many part of the work does A complet

anzhelika [568]

Answer:

1/5

Step-by-step explanation:

Well work can be defined as: $work = rate \ *\ time$

where rate=amount of work that can be done in one unit of time

let a = rate of work A does in a day

let b = rate of work B does in a day

this means that: $10a + 10b=1$ where work=1 and it just means the entire job has been completed.

Since b can do it alone in 15 days, this means that: $15b=1$

If we divide by 15 here, we get the equation: $b=\frac{1}{15}$

We can now use this definition to substitute it into the first equation we made.

$10a + 10(\frac{1}{15}) = 1$

Multiply the 10 and 1/15

$10a+\frac{2}{3}=1$

subtract 2/3 from both sides

$10a=\frac{1}{3}$

Now divide both sides by 10

$a=\frac{1}{30}$

Now multiply this by 6, since we a represents the amount of work that can be done in a day, we want to find how many parts of the work can be done by a in 6 days

$6a=\frac{6}{30}$

Now divide both the numerator and denominator by 6

$a=\frac{1}{5}$

works as a florist and worked 12 hours last week and earned $98. At that rate, how much will she earn this weekend if she works

kotykmax [81]

Answer:

$114.3

Step-by-step explanation:

Number of hours worked last week = 12hrs

Amount earned for her work hours = $98

The rate at which she earned = ?

Rate = $\frac{amount earned }{total work hour}$

Rate = $\frac{98}{12}$ = $8.17/hr

Now;

Since the total hours she worked during the weekend = 14hrs

Amount earned = $8.17/hr x 14hrs = $114.3
