Let's take length of HK = n
By using trigonometry,
[tex] \sin(30) = \dfrac{22}{n} [/tex][tex] \dfrac{1}{2} = \dfrac{22}{n} [/tex][tex]n = 44[/tex]Hence, value of HK = 44 cm
[tex]\\ \rm\Rrightarrow sin\theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]
[tex]\\ \rm\Rrightarrow sin30=\dfrac{JK}{HK}[/tex]
[tex]\\ \rm\Rrightarrow sin30=\dfrac{22}{HK}[/tex]
[tex]\\ \rm\Rrightarrow HK=\dfrac{22}{sin30}[/tex]
[tex]\\ \rm\Rrightarrow HK=44[/tex]

Answer:
[tex]x(x - 1) - {x}^{2} + 2x = 5 \\ {x}^{2} - x - {x}^{2} + 2x = 5 \\ \therefore \: x \: = 5[/tex]
Answer:
x=5
Step-by-step explanation:
[tex]x(x-1)-x^2+2x=5[/tex]
expand by using distributive property
[tex]x^2-x-x^2+2x=5[/tex]
simplify
x=5
check work by substituting 5 into the original equation and simplify
use PEMDAS
[tex]5(5-1)-5^2+2(5)=5[/tex]
[tex]5(4)-25+10=5[/tex]
add and subtract (left to right)
20-25+10=5
5=5
The equation is true, thus x=5
Julie ran 7/8 of a mile. Kelly ran 1/3 of a mile.. How much farther did Julie run?
Answers
2-3/4 equals 11/4.
Since this a unit rate problem divide the miles by the time traveled.
11/4 (miles) ÷ 1/3 (hour). When you divide a number by a fraction use (Keep-Change-Flip).
11/4 × 3/1 = 33/4 miles/hour.
Convert improper fraction to mixed number by dividing 33 by 4.
33/4 = 8-1/4 miles/ hour.

-
o D. 6.8-6. 1 / 3
C.
6
- 6-8
Answers
Answer:
Answer: Option D
Answer: Option DStep-by-step explanation:
• In distributive property, we multiply the factor to each term in the bracket. So that the reverse is true.
Take an example;
[tex] \dashrightarrow \: { \rm{x(y + z)}}[/tex]
• To apply distributive property, mulyiply both y and z by x following the addition operation.
summary:
[tex] \dashrightarrow \: { \rm{xy + xz}}[/tex]
→ The expression above is the expansion using distributive property.
• Back to the question, we are given a factorised expression;
[tex]{ \rm{6(8 - \frac{1}{3} )}} \\ [/tex]
• To apply the distributive property, multiply 8 and ⅓ by 6:
[tex] \dashrightarrow \: { \boxed{ \boxed{ \rm{ \: (6 \: • \: 8 - 6 \: • \: \frac{1}{3}) }}}} \\ [/tex]

In how many ways can 8 diplomats be seated at a round table?
A)40,320
B)5,040
C)720
Answers
Answer:
5040Step-by-step explanation:
Now, imagine a specific arrangement. Now, have everyone get up and move one seat to their right. That arrangement was counted separately from the first one in the 8! but it’s really the same since if each person looks to their left and their right, they’re sitting next to the same person. There are 8 such “identical rotations” for each possible seating arrangement so the total number of seatings is 8! / 8 = 7! = 5040.HOPE IT HELPS
