Hello! To find the sales tax rate, all you have to do is divide the amount of tax by the amount before tax. 11.4/380 is 0.03. Because percents are parts of 100, multiply that decimal by 100 in order to get 3. There. The sales tax rate is 3%.

How to find degrees in triangle using trig?

Remember SOHCAHTOA

Sine- opposite/hypotenuse
Cosine- adjacent/hypotenuse
Tangent- opposite/adjacent

Look at the angle (x) you are trying to figure out and pick which one of these it is.

In your calculator, do the equation first to get a decimal

Then press whichever one you chose on the calculator, so if you got like 0.2 by doing opposite/adjacent for tangent, you would type in 0.2 and then the TAN button

hope this makes sense!!

for every 5 coins carmen gets, she gives 2 to her brother Frankie. If carmen has 9 coins, how many does frankie have?
aliya0001 [1]
Since Carmen gives two coins to Frankie for every five that she gets, she effectively only gains 3 coins at a time. Therefore, if she has 9 coins, Frankie must have 6.

8. Solve the following triangle for all missing sides and angles.
vova2212 [387]

Answer:

Parte1 :

∡B= 180 - (42 + 83)= 55°

Parte2 :

Using the law of sines : \frac{sin 42}{a} = \frac{sin 55}{175} ⇔ a = sin42 \frac{175}{sin 55} ⇔ a= 142.95

Parte3 :

Using the same law : c = sin 83\frac{a}{sin 42}  or  c= sin 83\frac{175}{sin 55}  ⇔ c= 212.04

The difference of a number and 6 is the same as 5 times the sum of the number and 2. What is the number?
S_A_V [24]

Step-by-step explanation:

Lets consider the unknown number as x

according to the question,

6-x= 5(x+2)

6-x= 5x+10

-x-5x=10-6

-6x=4

x=4/-6= 2/-3

x= -2/3

In a video game, Agnes scored 20% fewer than Amy. Amy scored 860
vovangra [49]

Answer:

\huge\boxed{\sf Agnes\ Score = 688\ points}

Step-by-step explanation:

\sf = 20 \% \ of \ 860 \\\\= \frac{20}{100} * 860\\\\= 2 * 86\\\\= 172 \ points

Since, Agnes scored 20 % fever than Amy.

So,

Agnes Score = Amy's Points - 20 % of Amy's Points

Agnes Score = 860 - 172

Agnes Score = 688 points

\rule[225]{225}{2}

Hope this helped!
