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%
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%

60 in scientific notation
Answer:
I think the answer would be 6.0x10¹
If 60 was in scientific notation it would look like 6.0 because there is only one zero and we would need to move the decimal one place to the right. So we multiply 10¹ so we can move that decimal to the right to make 60.

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
We are given that;
The four options
Now,
This is because the electric field at a point in space is in the direction of the force that the electric field would exert on a positive test charge if there were a positive test charge at that point in space1. Because positive charges repel each other, the electric field around an isolated positive charge is oriented radially outward.
Therefore, by unitary method the answer will be Lines with arrows that point outward radiate from the charge in all directions.

1. JP Construction is building a rectangular children's wading pool for the local community center. The pool will be 4.5 meters wide. To meet city building code guidelines, the area of the pool must not be larger than 8 square meters. Which inequality represents the possible lengths of the wading pool, where x represents the length of the wading pool in meters?
Answer:
[tex]x\leq 1.78[/tex]
Step-by-step explanation:
We are given that
Width of pool, b=4.5 m
We have to find the inequality which represents the possible lengths of the wading pool.
Let x be the length of wading pool
We know that
Area of rectangle=[tex]length\times breadth[/tex]
According to question
Using the formula
[tex]4.5x\leq 8[/tex]
Divide by 4.5 on both sides we get
[tex]x\leq\frac{8}{4.5}[/tex]
[tex]x\leq 1.78[/tex]
