Answer:

67 degrease

Step-by-step explanation:

angle #1 = 23

angle #2 = 90

angle #3 = ?

#1 + #2 + #3 = 180

23 + 90 + ? = 180

180 - (23 + 90) = ?

180 - 113 = ?

? = 67

A test requires that you answer first Part A and then either Part B or Part C. Part A consists of 4 true false questions, Part B

erma4kov [3.2K]

Answer: 374416

Step-by-step explanation:

Given : A test requires that you answer first Part A and then either Part B or Part C.

Part A consists of 4 true false questions, Part B consists of 6 multiple-choice questions with one correct answer out of five, and Part C consists of 5 multiple-choice questions with one correct answer out of six.

i.e. 2 ways to answer each question in Part A.

For 4 questions, Number of ways to answer Part A = $2^4$

5 ways to answer each question in Part B.

For 6 questions, Number of ways to answer Part B = $5^6$

6 ways to answer each question in Part C.

For 5 questions, Number of ways to answer Part C = $6^5$

Now, the number of ways to completed answer sheets are possible :_

$2^4\times5^6+2^4\times6^5\\\\=2^4(5^6+6^5)\\\\=16(15625+7776)\\\\=16(23401)=374416$

Hence, the number of ways to completed answer sheets are possible = 374416

The right answer is Option A: $x=\frac{rs-t}{2}$

Step-by-step explanation:

Given expression is;

$s=\frac{2x+t}{r}$

We will solve this expression for x, therefore,

Multiplying both sides by r

$r*s=\frac{2x+t}{r}*r\\rs=2x+t$

Subtracting t from both sides

$rs-t=2x+t-t\\rs-t=2x\\2x=rs-t$

Dividing both sides by 2

$\frac{2x}{2}=\frac{rs-t}{2}\\x=\frac{rs-t}{2}$

The right answer is Option A: $x=\frac{rs-t}{2}$
