Answer: 42.9%

Step-by-step explanation:

Percent error is the difference between the measured and known value, which is divided by the known value, and then multiplied by 100%.

Percent error = (Estimated number- Actual number)/Actual Number × 100.

= (60 - 42)/42 × 100

= 18/42 × 100

= 0.429 × 100

= 42.9%

LA and B are vertical angles. If mZA = then find the value of x. (7x – 27) and m B = (3x + 29)°,
zhuklara [117]

we know that

Vertical angles are congruent angles

that means

substitute the given values

(7x – 27)=(3x + 29)

solve for x

7x-3x=29+27

4x=56

x=14

part b)

We know that

Supplementary angles are angles that their sum is equal to 180 degrees

so

A+B=180

substitute the given values

5x+25+x+17=180

solve for x

6x+42=180

6x=180-42

6x=138

x=23

Solnce55 [7]

Answer:

See explanation

Step-by-step explanation:

Given two expressions:

2(s+0.5)+2(s+1.5)

and

4\left(\dfrac{1}{2}s+\dfrac{1}{4}s\right)+4

a. When s=0,

then

2(s+0.5)+2(s+1.5)=2(0+0.5)+2(0+1.5)=1+3=4

and

4\left(\dfrac{1}{2}s+\dfrac{1}{4}s\right)+4=4\left(\dfrac{1}{2}\cdot 0+\dfrac{1}{4}\cdot 0\right)+4=4

b. When s=12,

then

2(s+0.5)+2(s+1.5)=2(12+0.5)+2(12+1.5)=2\cdot 12.5+2\cdot 13.5=25+27=52

and

4\left(\dfrac{1}{2}s+\dfrac{1}{4}s\right)+4=4\left(\dfrac{1}{2}\cdot 12+\dfrac{1}{4}\cdot 12\right)+4=4(6+3)+4=4\cdot 9+4=36+6=40

c. Since the value of both expressions at s = 12 are different, the expressions are not equivalent.
