Answer:
2/1 or 2
Step-by-step explanation:
8/4 is 2
9/9 is 1
Answer: 46 degrees
Step-by-step explanation: First you need to find the value of the vertical angle which is 180-(85+53) which is 42 degrees. Since vertical angles are congruent, you can say that 180-(42+92) is equal to x. When you solve it, you get x=46 which is your answer
Answer:
∠ LOM = 48°
Step-by-step explanation:
∠ LOM +∠ MON = 180 ( straight angle ), that is
7x - 92 + 6x + 12 = 180
13x - 80 = 180 ( add 80 to both sides )
13x = 260 ( divide both sides by 13 )
x = 20
Thus
∠ LOM = 7x - 92 = 7(20) - 92 = 140 - 92 = 48°
First, to make things easier, rewrite the equation
3(65+7)+2
2. distribute the 3 inside the parentheses
3 * 65 = 195 3 * 7 = 21
3. add the products together
195 + 21 = 216
4. add 216 to the remaining term, 2.
216 + 2 = 218.
the answer is 218
Step-by-step explanation:
1. The first step has 1 block. The second step has 2 blocks. The third step has 3 blocks. So the nth step needs n blocks.
2. A staircase with n steps has 1 + 2 + 3 + ... + n steps. This is an arithmetic sequence where the first term is 1 and the last term is n. The sum of the first n terms is:
y = n/2 (1 + n)
3. Solve for n.
2y = n (1 + n)
2y = n² + n
0 = n² + n − 2y
Using quadratic formula:
n = [ -1 ± √(1 − 4(1)(-2y)) ] / 2
n = [ -1 + √(1 + 8y) ] / 2
