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%

A school board voted whether to adopt new math books. Those that voted yes
out numbered those that voted no by a ratio of 5 to 1. If 18 school board
members voted, how many voted yes for new math books and how many
voted no?
Answer:
15 people voted yes and 3 people voted no.
Step-by-step explanation:
Given that:
Ratio of yes to no = 5 : 1
Total number of board members who voted = 18
Let,
x be the number of times.
5x+x = 18
6x = 18
Dividing both sides by 6
[tex]\frac{6x}{6}=\frac{18}{6}\\x=3[/tex]
People who voted yes = 5(3) = 15
People who voted no = 3
Hence,
15 people voted yes and 3 people voted no.

Answer:
D. 2/5
Step-by-step explanation:
The slope is the x-coefficient when the equation is solved for y.
2x -5y = 9 . . . . . . . given
-5y = -2x +9 . . . . . .subtract 2x
y = (-2/-5)x +9/(-5) . . . . divide by -5
y = 2/5x -9/5
The coefficient of x is 2/5. That is the slope of the line.
The slope is 2/5.

Answer:
yes i will help you
Step-by-step explanation:what are you struggling with
Answer:
A
Step-by-step explanation:
Given similar figures with ratio of sides = a : b , then
ratio of areas = a² : b²
ratio of sides = 15 ; 18 = 5 ; 6
The ratio of perimeters is equal to the ratio of sides, so
ratio of perimeters = 5 : 6
ratio of areas = 5² : 6² = 25 : 36
if x is 18 when y is 6 find y when x is 21
Answer:
y = 7, when x = 21
Step-by-step explanation:
Since 6 is 1/3 of 18 we could use that to find y
1/3 x 21 = 7

The opening judgment of Fever 1793," From the moment Colette Ogilvie passed out, Philadelphia's church bells chimed continuous.
The narrator of Fever 1793 makes it easy for readers to picture her upbringing by expressing her love for the nation, describing how it felt to see her words printed, confessing to counting on her fingers, and describing how it felt to voice her anger with front-of-the-house service.
On the road corners, shots were fired, and a cannon was fired in the public forecourt to clear the air. In addition to that, hornets, blowflies, and mosquitoes swarmed about us continuous.
The noise was annoying." Illustration demonstrates how mosquitoes, blowflies, and hornets agonized Philadelphians with unheroic fever in 1793.

show that each quadrilateral with the given vertices is a parallelogram.
J(-2,-2), K(-3,3), L(1,5), M(2,0)
9514 1404 393
Answer:
J +L = K +M = (-1, 3)
Step-by-step explanation:
The figure JKLM is a parallelogram if the midpoints of the diagonals are the same point. That is, ...
(J +L)/2 = (K +M)/2
Multiplying by 2 makes this a simpler test:
J +L = K +M
In this quadrilateral, those sums are ...
J +L = (-2, -2) +(1, 5) = (-2+1, -2+5) = (-1, 3)
K +M = (-3, 3) +(2, 0) = (-3+2, 3+0) = (-1, 3)
The midpoints are the same, so the quadrilateral is a parallelogram.

what's the gcf of 3x and 12x
Answer: GCF- is 3x
Step-by-step explanation:
So first you will ignore the X.
You will then find the GCF of 3 and 12.
The calculated value of the gcf of 3x and 12x is 3x
Calculating the gcf of 3x and 12xFrom the question, we have the following parameters that can be used in our computation:
Expressions = 3x and 12x
Expand both expressions
So, we have
3x = 3 * x
12x = 2 * 2 * 3 * x
Multiply the common factors
GCF = 3 * x
Evaluate
GCF = 3x
Hence, the gcf of 3x and 12x is 3x

Joe buys a compact disc that costs $29.99. He give the store clerk $50.00.
How much change should he get?
Answer:
$20.01
Step-by-step explanation:
Simply subtract $29.99 from $50.00 so, your problem should be set up like this:
You substitute the numbers with 10s, but there cannot be more than one.
Answer:
$20.01
Step-by-step explanation:
You should subtract 50.00 and 29.99, and since there are three zeros, you have to borrow from the five, making it a four. Then, you make the first zero into a 10, then borrow from that one, making it a nine, same with the second zero. Then, for the third zero, you only borrow one from the second zero, turning the second one into a nine and the third on into a 10. You then start the subtracting process. This is the first part to the problem:
50.00 - 29.99 = ?
Then, this is what you should have after:
49.91(0) - 29.99 = ?
This is what you get after:
20.01
Then, add the dollar sign. You will get:
$20.01

Helena has saved $595 to put toward snowboarding equipment and lift tickets at the hill. Each lift ticket costs $35. If she wants to have more than $420 of her savings left to spend on equipment, which inequality represents the number of lift tickets she can buy? A. X<5 B. X<4 (there is a line _ underneath the >) C. X>7 D. X>7 (there is a line _ underneath the >)
Answer:
[tex]x < 5[/tex]
Step-by-step explanation:
Given
[tex]Savings = \$595[/tex]
Rate of Lifting Ticket = $35 per ticket
Expected Amount = More than $420
Required
Determine the number of tickets she can buy
If the cost of lifting 1 ticket is 35, then the cost of x tickets is 35x.
Her spendings is then calculated as:
Total = Savings - Cost of lifting tickets
[tex]Total = 595 - 35x[/tex]
From the question, we understand that she wants to have more than 420 left.
This is represented as:
[tex]595 - 35x > 420[/tex]
Collect Like Terms
[tex]- 35x > 420 - 595[/tex]

State the domain restriction(s) in interval notation of \displaystyle f\left(g\left(x\right)\right)f(g(x)) given: \displaystyle f\left(x\right)=\sqrt{3x-2}f(x)= 3x−2 and \displaystyle g\left(x\right)=x-7g(x)=x−7
Answer:
The interval notation for the domain is [tex][\frac{23}{3},\infty ][/tex].
Step-by-step explanation:
Consider the provided information.
It is given that [tex]\:f\left(x\right)=\sqrt{3x-2},\:\text{ and }\:g\left(x\right)=x-7[/tex]
We need to find the value of [tex]f\left(g\left(x\right)\right)[/tex].
Put the value of g(x) in [tex]f\left(g\left(x\right)\right)[/tex].
[tex]f\left(g\left(x\right)\right)=f(x-7)[/tex] ....(1)
Now, put x=x-7 in [tex]\:f\left(x\right)=\sqrt{3x-2}[/tex]
[tex]\:f\left(x-7\right)= \sqrt{3(x-7)-2}[/tex]
[tex]\:f\left(x-7\right)= \sqrt{3x-21-2}[/tex]
[tex]\:f\left(x-7\right)= \sqrt{3x-23}[/tex]
From equation 1.
[tex]f\left(g\left(x\right)\right)=\:f\left(x-7\right)= \sqrt{3x-23}[/tex]
The domain of the function is the set of input values for which a function is defined.
Here, the value of [tex]3x-23[/tex] should be greater or equal to 0 as the square root of a negative number is not real.
Domain= [tex]3x-23\geq0[/tex]
[tex]x\geq\frac{23}{3}[/tex]
The value of x is all real number greater than [tex]\frac{23}{3}[/tex].
Hence, the interval notation for the domain is [tex][\frac{23}{3},\infty ][/tex].
