Answer: -7.408%
Explanation: The formula for percent error is:
(experimental - theoretical) / theoretical * 100. The experimental value is 50, or your guess. The theoretical value is 54, or the actual value. The theoretical value is the value it should be.
(50-54)/54 = -.074 * 100 = -7.408%
Answer:
The total cost for 8 skiers=316 dollars
Step-by-step explanation:
Given that the expression 15n+12n+100 represents the total cost in dollars for skis,boots and a lesson for n skiers.
To simplify the given expression :
15n+12n+100=27n+100
27n=-100
Therefore 
Now to find the total cost for 8 skiers.
The total cost for 8 skiers can be written as below
Put n=8 in the given expression 15n+12n+100
15(8)+12(8)+100
=120+96+100
=316
Therefore the total cost for 8 skiers is 316 dollars
The total cost for 8 skiers=316 dollars
Answer:
31 vacuums
Step-by-step explanation:
1800 = 250 + 50v
1800 - 250 = 50v
50v = 1550
v = 1550 / 50
v = 31
He sold 31 vacuums.
The unknown angles in the cyclic quadrilateral is as follows:
∠BGX = 74° (sum of angles in a triangle)
∠BGF = 180° (opposite angles of cyclic quadrilateral are supplementary)
∠BCF = 100°(sum of angles in a triangle)
∠BCG = 26°
∠BFG = 22°
<h3>Cyclic Quadrilateral</h3>
A cyclic quadrilateral has all its angles equal to 360 degrees. The sum of angles in a cyclic quadrilateral is equals to 360 degrees.
Let's find the missing angles as follows:
∠BGX = 180 - 48 - 58 = 74° (sum of angles in a triangle)
∠BGF = 180 - 100 = 80° (opposite angles of cyclic quadrilateral are supplementary)
∠BCF = 180 - 22 - 58 = 100°(sum of angles in a triangle)
∠BCG = 100 - 74 = 26°
∠BFG ≅ CBF = 22°(alternate angles)
