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%

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

CL 3-116. For the points R(-2, 7) and P(2,1) determine each of the following:
9514 1404 393
Answer:
Jermaine and Sadie have similar triangles. Aisha's is not similar.
Step-by-step explanation:
The side lengths can be arranged smallest-to-largest and reduced to mutually-prime integers. If the triangles are similar, their side ratios will be the same.
Jermaine's triangle has side ratios ...
8 : 14 : 20 = 4 : 7 : 10
Sadie's triangle has side ratios ...
2 : 3.5 : 5 = 4 : 7 : 10 . . . . (same as Jermaine's)
Aisha's triangle has side ratios ...
4 : 10 : 16 = 2 : 5 : 8 . . . . . (different from Jermaine's)
Sadie and Jermaine have similar triangles.

In Toronto, Canada, one liter of gasoline costs. $0.74$. There are 3.8 liters in one gallon. How much does one gallon of gas cost in Toronto? Round your answer to he nearest hundredths.
Answer:
$2.81
Step-by-step explanation:
From the above question:
1 liter of gasoline = $0.74
There are 3.8 liters in one gallon.
Hence:
1 liter of gasoline = $0.74
3.8 liters of gasoline = x
Cross Multiply
x = 3.8 × $0.74
x = $2.812
Approximately to the nearest hundredth = $2.81
Therefore , the cost of one gallon of gas(3.8 liters) in Toronto is $2.81

Prove algebraically that the recurring decimal 0.472 can be written as

36
Given:
The recurring decimal is [tex]0.47\overline{2}[/tex].
To prove:
Algebraically that the recurring decimal [tex]0.47\overline{2}[/tex] can be written as [tex]\dfrac{17}{36}[/tex].
Proof:
Let,
[tex]x=0.47\overline{2}[/tex]
[tex]x=0.472222...[/tex]
Multiply both sides by 100.
[tex]100x=47.2222...[/tex] ...(i)
Multiply both sides by 10.
[tex]1000x=472.2222...[/tex] ...(ii)
Subtract (i) from (ii).
[tex]1000x-100x=472.2222...-47.2222...[/tex]
[tex]900x=425[/tex]
Divide both sides by 900.
[tex]x=\dfrac{425}{900}[/tex]
[tex]x=\dfrac{17}{36}[/tex]
So, [tex]0.47\overline{2}=\dfrac{17}{36}[/tex].
Hence proved.

Side ratios are not the same. In the top triangle, the length ratios are ...

In the bottom triangle, the length ratios are ...
7 : 8 : 19 (such a triangle cannot exist)
Since the ratios are not the same, the triangles are not similar.

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.

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.

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

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
