Diego measured the length of a pen to be 22 cm. The actual length of the pen is 23 cm. Which of these is closest to the percent error for Diego's measurement? WITH EXPLANATION please and thank you :)
Answer:
4.34%
Step-by-step explanation:
Given that,
The measured length of a pen = 22 cm
Actual length of the pen = 23 cm
We need to find the percent error for Diego's measurement. It can be calculated as follows :
[tex]\%=\dfrac{23-22}{23}\times 100\\\\=4.34\%[/tex]

Answer:
25
Step-by-step explanation:
Given,
Measurement of <1 = x + 10
Measurement of <2 = 4x + 5
Also, said in the question that both these angles are complementary.
Therefore, by the problem,
<1 + <2 = 90°
=> x + 10 + 4x + 5 = 90
=> x + 4x + 10 + 5 = 90
=> 5x + 15 = 90
=> 5x = 90 - 15 = 75
[tex] = > x = \frac{75}{5} [/tex]
=> x = 15
Now, we have got the value of x so,
Measurement of <1 is
<1 = x + 10 = 15 + 10 = 25 (Ans)

The diagram shows two right-angled triangles. Calculate the value of x.
The value of x in the given diagram is 7cm.
What is tangent of an angle?The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
According to the given question.
We have a diagram in which we have two right angled triangles.
Now, in the upper right angled triangle
[tex]tan50 = \frac{0pposite side}{5}[/tex]
⇒ 1.19 = 0pposite side/ 5
⇒ opposite side = 1.19 × 5
⇒ opposite side = 1.2 × 5
⇒ opposite side = 6cm
Now, the opposite side w.r.t angle 50 degrees in the upper right angle triangle is a adjacent side w.r.t to angle 38 degrees in the lower right angle triangle.
So, in the lower right angle triangle.
[tex]tan38 = \frac{x}{adjacent side}[/tex]
⇒[tex]0.78 = \frac{x}{6}[/tex]
⇒ x = 0.78 × 6
⇒ x = 4.68
⇒ x = 7cm
Hence, the value of x in the given diagram is 7cm.

49 is a perfect square it'll be 7
Step-by-step explanation:
An expression has a leading coefficient that is a perfect square is 49w²+4+53.
What is a perfect square?A perfect square is a positive integer that is obtained by multiplying an integer by itself. In simple words, we can say that perfect squares are numbers that are the products of integers by themselves.
The term with the highest degree i.e., the term with the largest power of the variable is the leading term. The leading coefficient is the leading term's coefficient.
In the polynomial 49w²+4+53
The highest degree is with the term 49w² is 2, and its coefficient is 49.
49=7×7=7²
So, 49 is the perfect square.
