Answer:
(2r - 8)(2r + 8).
Step-by-step explanation:
4r2 – 64
This is the difference of 2 squares so we take the square root of 4r2 and 64 and write:
= (2r - 8)(2r + 8).
If the height of the triangle will be 6.28 meters. Then the value of x will be 8.46 meters.
<h3>What is the triangle?</h3>
A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
In the diagram shown, the area of the triangle is 44.3 m².
If b = 14.1 m and the angle at C = 48°.
Then the value of x will be
The height of the triangle will be
A = 1/2 × B × H
44.3 = 1/2 × 14.1 × h
h = 6.28 m
Then the value of x will be
sin 48° = 6.28 / x
x = 8.455 ≈ 8.46 m

Answer:
1st option is correct.
Step by step explanation:
Let us see our given options one by one.
1. We can see that median of group A is 79 and median of group B is 79.5. Therefore, median of group A is less than group B and 1st statement is correct.
2. Let us find range of each group.
We can see that range of group A is greater than group B, therefore, 2nd statement is false.
3. The lower quartile of group A is 78 and lower quartile of group B is 77. We can see that 78 is greater than 77, therefore, 3rd statement is false.
After applying inverse operation we get
Step-by-step explanation:
We need to solve using inverse operation of
Solving:
Adding -12 on both sides:
Divide both sides by 6
So, after applying inverse operation we get

Answer:
Step-by-step explanation:
Let m = Number of months
Combined charges for music sharing service = 25+6m
Cost of joining to company = $70
According to the question,
Combined charges > Cost of joining to company (To find number of months it would take for this)
