Answer:
25%
Step-by-step explanation:
percent error is found by the equation(measured-real)/real x 100
20 is the measured value and 16 is the real value
(20-16)/16 x 100
4/16 x 100
0.25 x 100
25
hope this helps!
Answer:
=1.99 sec
Step-by-step explanation:
t=k√d
k= constant
3=k√34.1
3=5.839k
k=0.5137
t=0.5137√15
t=1.99 sec
Answer:
y = 
Step-by-step explanation:
given y varies as the square of x then the equation relating them is
y = kx² ← k is the constant of variation
to find k use the given condition y = 25 when x = 3
k = 
= 
⇒ y = x²
when x = 2
y = × 4 =
Answer:
Angle k = 14°,L = 70° and N = 96°
Step-by-step explanation:
According to the question,Enzo drew Triangle K L N. In Enzo’s triangle, Measure of angle K is represented as x degrees. The measure of Angle L is 5 times Measure of angle K. The measure of Angle N is 16 degrees less than 8 times Measure of angle K.
From here,we know that angles in a triangle sum up to 180°
If angle k = x
Angle L = 5x
And angle N = 8x - 16
Sum of a all three is equal to 180°
(8x - 16) + x + 5x = 180
14x -16 = 180
X = 196/14
X= 14.
Therefore,angles k = 14°, L = 70° and N= 96°
Let's now assume that the question was to find the angles k,l and n which is already written above and to pick the correct statement relating to the question.
My statement here is( since we weren't given the complete question) that the triangle is a scalene triangle
We name angles in three different ways:
(1) We can name angles by using THREE capital letters like: ABC or DEF. The middle letter is called the VERTEX of the angle. The above angles are read "angle ABC" and "angle DEF." This leads us to the second way we can name angles.
(2) We can name angles by using the vertex. For example, ABC, can also be called angle B; the same applies to DEF (we can call angle DEF angle E). Of course, if there's more than one angle sharing the same vertex this would be confusing!
(3) We can also name an angle by placing any number or symbol at the vertex in the INTERIOR of the angle. So, angles can also be called angle 1 or angle 2 or angle 4, etc.
