Which of the following congruence statements are correct?
solong [7]
Only B and F are true. The letters are set up so the parts that you choose must have the letters in the same place on each triangle.

So if ABC is a triangle congruent to PQR
Then AB is congruent to PQ because AB are the first 2 letters of ABC and PQ are the first 2 letters of PQR.
AC is congruent to PR (why?)

Lisa buys a television for $4185. if the sales tax is $292.95. what percent is sales tax?
Romashka-Z-Leto [24]

Answer:

Sales tax = 7%.

Step-by-step explanation:

Let x be the percent of sales tax.

We have been given that Lisa buys a television for $4185. The sales tax is $292.95.

We need to figure out x such that x percent of 4185 equals to 292.95. Let us represent this information in an equation.

\frac{x}{100}*4185=292.95

Let us multiply both sides of equation by 100.

100*\frac{x}{100}*4185=100*292.95

x*4185=29295

x=\frac{29295}{4185}

x=7

Therefore, sales tax is 7%.

Let us cross check our answer by calculating 7% of 4185.

7\%\text{ of } 4185=\frac{7}{100}\times 4185

7\%\text{ of } 4185=0.07\times 4185

7\%\text{ of } 4185=292.95

We can see that 7% of 4185 is 292.95. Hence, sales tax is 7%.
