The perimeter of a triangle is 22cm. If one of the sides is 9cm, find the other sides if the area of the triangle is 20.976cm2
Answer:
6 cm and 7 cmStep-by-step explanation:
GivenA triangle with:
P = 22 cmA = 20.976 cm²a = 9 cmTo find Other sides of the triangleSolutionLet the missing sides be b and c
The perimeter is
P = a + b + cSubstitute known values
22 = 9 + b + cb + c = 13c = 13 - bUse Heron's formula for the area:
A = √s(s-a)(s-b)s-c), where s is half-perimeters = 22/2 = 11Substitute s, a and c and solve for b:
√11(11 - 9)(11 - b)(11 - c) = 20.976√11*2(11 - b) (11 - 13 + b) = 20.976√22(11 - b)(b - 2) = 20.976Square both sides
22(11 - b)(b - 2) = 20.976²22(11 - b)(b - 2) ≈ 440(11 - b)(b - 2) = 20 13b - b² - 22 = 20b² - 13b + 42 = 0b = (13 ± √13² - 4(42))/2b = (13± 1)/2b = 6, b = 7Find c:
c = 13 - bc = 6, c = 7So missing sides are 6 cm and 7 cm

Jim was thinking of a number. Jim halves it and gets an answer of 3.4. What was the original number?
Answer:
6.8
Step-by-step explanation:
To tackle these types of questions, you essentially have to 'undo' or ' reverse' the calculation/s that is being done in the question.
In the question, the calculation that is being done is 'halfing' or 'dividing by 2'.
So to find the original number you have to do the opposite - double or 'multiply by 2'
Therefore
3.4 x 2 = 6.8

1. JK = LM, JKM = LMK -> This is given information.
- From this given information, we know:
1. 2 congruent sides
2. 2 congruent angles
Now all we have to do is find one more side to prove SAS triangle congruence.
Next, we notice that the side MK is used by both the triangles we are trying to prove congruent. So we can say "MK = MK" by the reflexive property. (Since they share the same side).
Then, we can say triangle JMK is = triangle LKM because of SAS congruence.
*Please note the = signs I used should be actually congruence signs*

Answer:
32.40cm²
Step-by-step explanation:
Given the parallelogram ABCD ;
side AB is always Parallel to CD, hence ;
AB = CD = 7.2cm
Perpendicular from C on AB is the height of the parallelogram = 4.5cm
Area of a parallelogram : base * height
Area of a parallelogram = length base * height
Area of a parallelogram = 7.2 cm * 4.5cm
Area of parallelogram = 32.40cm²

Mike bought a box of 12 golf balls for $18. Solve the equation 12x=$18 to find the price of each golf ball. $1 25, $1 50, $1 75 are the options. Choose one and please show work.
Answer:
The price of each golf is $ 1.50
Step-by-step explanation:
Given;
Price of 12 golf balls = $18
Let the price of 1 golf ball = x
Price of 12 golf balls = 12x
But the total price of the 12 golf balls = $18
Thus, 12x = $18
x = $18 / 12
x = $ 1.50
Therefore, the price of each golf is $ 1.50
