The correct answer is 336.
How do you calculate an arrangement?Remember that combinations are a way to calculate the total outcomes of an event where the order of the outcomes does not matter. To calculate combinations, we will use the formula NCR = n! / r! * (n - r)!, where n represents the number of items, and r represents the number of items being chosen at a time.

What is the quotient of 4.644 x 10^8 and 6.45 x 10^3 expressed in scientific
notation?
Answers
Answer:
7.2 x 10^4
Step-by-step explanation:
The quotient of 4.644 x 10⁸ and 6.45 x 10³ expressed in scientific notation is 7.2 x 10⁴.
What is the quotient of division?The quotient of 4.644 x 10⁸ and 6.45 x 10³ expressed in scientific notation, is calculated as follows;
(4.644 x 10⁸) / (6.45 x 10³) = (4.644 / 6.45) x (10⁸ / 10³)
Calculating the division:
= 72,000
Now, we need to express the result in scientific notation. Move the decimal point to the left until there is only one non-zero digit to the left of the decimal point.
= 72,000
= 7.2 x 10⁴
So, the quotient of 4.644 x 10⁸ and 6.45 x 10³ expressed in scientific notation is approximately 7.2 x 10⁴.

x=5
Step-by-step explanation:
Since these angles are vertical angles formed by two parallel lines being intersected by another vertical line, you can set the 18x and 17x+5 equal to each other. Then you solve using algebra. I hope this helps!
Answer:
x=5
Step-by-step explanation:
Because they both equal 90°, you can use the equations, 18x=90 and 17x+5=90 to solve.
First, 18x= 90: (Divide by 18)
x=5
Now, 17x+5=90: (Subtract 5 from both sides)
17x= 85
Then divide by 17:
x= 5

Can someone help me find m
Answers
Answer:
69 degrees
Step-by-step explanation:
m is a point, if your trying to find lkh, is 69
lkm=111, and jkl=180, so 180-111=jkm
jkm=69
angles that are diagonal from each other are the same degree
lkh=69
hope this helps, if not see me in the commnets
HOPE THIS HELPS, BRAINLIEST PLEASE
Answer:
m < LKH = 69°
Step-by-step explanation:
Given that m < LKM = 111° and that:
<LKM and <LKH are adjacent angles as they share the same vertex, point K, and same ray between them, KL:
Then we can assume that m < LKM and m < LKH are supplementary angles whose sum = 180°.
Therefore, we can establish the following equation:
m < LKM + m < LKH = 180°
111° + m <LKH = 180°
Subtract 111° from both sides to solve for m < LKH:
111° - 111° + m <LKH = 180° - 111°
m < LKH = 69°
Therefore, the measure of < LKH is 69°.
