Jamal needs to purchase a countertop for his kitchen. Jamal measured the countertop as 5 ft. The actual measurement is 4.5 ft. What is Jamal’s percent error?
A) 5%
B) 11%
C) 45%
D) 50%

Answers

Answer:

percent error is 11.1% (which agrees with answer B)

Step-by-step explanation:

The discrepancy (difference) between the measurement and the real length was: 5 - 4.5 = 0.5 ft

Then the percent difference is calculated as:

(difference / real value) * 100 = ( 0.5 / 4.5ft ) * 100 = 11.1%

Maria recently hired a plumber to do some necessary work. On the final bill, Maria was charged a total of $473. The amount listed for parts was $335 and the rest of the bill was for labor. If the hourly rate for labor was $46, how many hours of labor was needed to complete the job?

(A) First write an equation you can use to answer this question. Use x as your variable. The equation is __________________

(B) Solve your equation in part (A) to find the number of labor hours needed to do the job. Answer: The number of labor hours was ________________________

Answers

Answer:

A)473 = 335 - 46x

B) 3

Step-by-step explanation:

473 = 335 - 46x

x = the hours of labor needed.

Solve for x

473 = 335 - 46x

subtract 335 from both sides

138 = 46x

divide both sides by 46

3 = x

Answer:

A) [tex]46x+335=473[/tex] B)[tex]x=3[/tex]

Step-by-step explanation:

473 is the total amount, which means it is the end result

335 represents a constant since it is a base price

the hourly rate is a variable, due to the fact that it depends on how many hours he spent working.

variable + constant = total price

[tex]46x+335=473[/tex]

Now to solve this, first subtract [tex]335[/tex] from both sides

[tex]46x=138[/tex]

Next divide both sides by [tex]46[/tex] to isolate the variable

[tex]x= \frac{138}{46}[/tex]

This can be simplified to: [tex]x=3[/tex]

?

6
ก
65

Answers

Answer:

Step-by-step explanation:

Answer:

(2/5)√5

Step-by-step explanation:

from the sine rule (see attached for reference), we can construct the following relationship

12/sinθ = (6√5) / sin 90°

recall that sin 90° = 1, hence our equation becomes:

12/sinθ = (6√5) / 1

12/sinθ = (6√5) (rearranging)

12 ÷ (6√5) = sin θ

sin θ = 12 / (6√5)

sin θ = 2 / √5 (moving radical to numerator by multiplying by √5/√5)

= 2 / √5 x √5/√5

= 2√5 / 5

= (2/5)√5
