A soccer field is 120 yards long. Han measures the length of the field using a 30-foot-long tape measure and gets a measurement of 358 feet, 10 inches. What is the amount of the error?
Answer:
Error = 1.167 feet
Percentage error = 0.3242%
Step-by-step explanation:
The original length of the soccer field = 120 yards long
Converting to feet
1 yard = 3 feet
120 yards = x
Cross Multiply
x = 120 × 3 feet
x = 360 feet
Measured length:
Han measures the length of the field using a 30-foot-long tape measure and gets a measurement of 358 feet, 10 inches.
We convert 10 inches to feet
1 inch = 0.0833 feet
10 inches = x feet
Cross Multiply
x = 10 × 0.0833 feet
x = 0.833 feet
The measured length = 358 feet + 0.833 feet
= 358.833 feet
The Error is calculated as:
|Measured length - Original Length)
= 360 feet - 358.833 feet
= 1.167 feet
Percentage Error
= Error/Original Length × 100
= 1.167/360 × 100
= 0.3241666667%
Approximately = 0.3242%

1)Ellen wanted to buy the following items:
∙ A DVD player for $49.95 ∙ A DVD holder for $19.95 ∙ Personal stereo for $21.95
Does Ellen have enough money to buy all three items if he has $90.s
Answer:
[tex]\huge\boxed{\tt{ No.}}[/tex]
Step-by-step explanation:
DVD player = $ 49.95
DVD Holder = $ 19.95
Personal Stereo = $ 21.95
Sum of Prices = $ 49.95 + $ 19.95 + $ 21.95 = $ 91.85
Ellan has $ 90 which is less than $ 91.85 which means that Ellan does not have enough to buy all three items.

4 ft = ?m
Answer:
1.2192
Step-by-step explanation:
There are 1.22 meters in 4 feet.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
We have,
1 meter = 3.28 feet
1 ft = 0.3048 m
Multiply 4 on both sides.
4 ft = 4 x 0.3048 m
4 ft = 1.2192 m
Rounding to the nearest hundredth.
4 ft = 1.22 m
Thus,
4 feet is equal to 1.22 meters.

Solve for x in the two equations below using substitution
12x-6y=60
24x+6y=300
Answer:
x = 10
Step-by-step explanation:
Given the 2 equations
12x - 6y = 60
24x + 6y = 300
Adding the 2 equations term by term will eliminate the y- term, that is
36x + 0 = 360
36x = 360 ( divide both sides by 36 )
x = 10
Find the inverse of the function f(x) = 2x - 4.
Answer:
f⁻¹(x) = 1/2 x + 2
Step-by-step explanation:
f(x) = 2x - 4 y=2x - 4
swap x and y: x = 2y - 4
solve y: 2y = x + 4
y = 1/2 x + 2
Inverse notation: f⁻¹(x) = 1/2 x + 2

–15 = a/5
A. a = –3
B. a = –20
C. a = –10
D. a = –75
Answer: a = -75
Step-by-step explanation:
i just multiplied both sides by 5, in order to get "a" by itself.
-75 = a
then, just for kicks, we switch it around so that the variable is in front.
a = -75

Answer:
13.5
Step-by-step explanation:
The longest side of the smaller triangle is 15 while that of the bigger one is 22.5
The enlargement ratio is 22.5/15 = 1.5
so the lengths of the smaller sides will be;
(1.5*9) = 13.5

Answer:
the answer is 144 feet and I don't really have an explanation
Answer:
Radius = 12 feet
Step-by-step explanation:
The area of a circle formula is Area = pi r^2 ("r" represents the radius)
The area of Circle Q is 144pi
You can substitute "Area" with 144pi, which would look like this:
144pi = pi x r^2
Now divide both sides with "pi", which gives:
144 = r^2
Finally, square root both sides:
sqrt(144) = sqrt(r^2) (sqrt = square root)
And that gives
12 = r
So the radius is 12 feet.
