Corbin is helping his grandfather plant the corn in the field. The field covers an area of 43,200 square feet. The length of the field is triple the width. What are the dimensions?
Answer:
the length is 360 feet and the width is 120 feet.
Step-by-step explanation:
Set up an equation with the area formula, A = lw
The width can be represented by x, and the length can be represented by 3x since it is 3 times the width
43,200 = (3x)(x)
43,200 = 3x²
Solve for x:
14,400 = x²
120 = x
So, the width is 120 feet.
The length is 3 times this, so multiply the width by 3 to find the length
120(3)
= 360
So, the length is 360 feet and the width is 120 feet.
(b) What is the probability that distance exceeds the mean distance by more than 2 standard deviations?
Answer:
>0.95
Step-by-step explanation:
This probably refers to a normal distribution. In a normal distribution, according to the empirical rule,
68% of observed data falls within 1 standard deviation of the mean
95% falls within 2 standard deviations of the mean
99.7% falls within 3 standard deviations of the mean
In this case, the observed data is distance and the average figure for all observed distances is the mean distance.
So, the probability that a/any distance observed exceeds the mean distance by more than 2 standard deviations is >95%
In other words, the probability is >0.95

17. N.Q.1-2 ULHS has a student that can run 100 yds in 15 seconds. Mrs. Duke's class converted his speed to
miles per hour below and determined he can run 4.55 miles per hour. Is the conversion correct? If not, explain
what the class did wrong and then work it out using dimensional analysis. You MUST Show all work.
100 yds
60 sec
60 min 1 mile
= 4.55 mph
15 sec
1 min 1 hr 5280 yds
Answer:
13.63 miles per hour
Step-by-step explanation:
100 yards / 15 sec converted to miles per hour
100 yards x 60 sec x 60 min x 1 mile = 13.63 miles/hr
15 sec 1 min 1 hr 1760 yards
the mistake on Mrs Dukes is the conversion from miles to yards.
1 mile = 1760 yards NOT 5280 yards
mg+rg=2H, solve for g
Answer:
g = 2H/(m + r)
Step-by-step explanation:
mg + rg = 2H
g(m + r) = 2H
(g(m + r))/(m + r) = 2H/(m + r)
g = 2H/(m + r)
The required solution of the algebraic expression for g is 2h / (m + r ).
Given that,
To simplify the algebraic expression mg+rg=2H for g,
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
the given algebraic expression is,
mg + rg = 2h
taking g common on left side,
g(m + r) = 2h
transposition of the term (m + r) to the denominator of the right-hand side,
g = 2h / (m + r)
The above expression is the required solution for the g.
Thus, the required solution of the algebraic expression for g is 2h / (m + r ).

This is a standard deviation contest. You must choose four numbers from the whole numbers 0 to 10 , with repeats allowed. (a) Choose four numbers that have the smallest possible standard deviation. What is s in this case? (Enter your answer rounded to the nearest whole number.)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following instructions :
Choose 4 numbers from the whole numbers 0 - 10
Note : Repetition is allowed
Choose 4 numbers with the smallest possible standard deviation.
The smallest possible value of standard deviation obtainable is 0;
Hence in other to obtain a standard deviation value of 0, then;
The mean squared deviation value must be zero (0)
Σ(X - mean)^2 = 0
To achieve this, the values of X and the mean must be the same.
Hence all 4 numbers (X) must be the same in other to have a mean value which is equal to X
For instance :
If X = 3, 3, 3, 3 (since Repetition is allowed)
Man value = (3+ 3+ 3+ 3) / 4 = 12 / 4 = 3
Σ(3 - 3)² = 0 for all values of x
√Σ(x - mean)² / n = 0 ; if all values of x are the Same
n = Number of observations
A possible list of values is (3,3,3,3)

If Mitzi has two dogs, a puppy that weighs 25 pounds and an adult that weighs 80 pounds, how much will it cost to bathe them both? $105 $115 $150 $160
Answer:
The correct answer is A) $105
Step-by-step explanation:
In this real-world problem, the cost to groom both dogs is (the puppy) + (the adult dog) = x.
For the first step, y = 40, if x <= 25.
y = 50, if 25 < x < 50.
if x >= 50, then y = 0.50x + 25
So therefore, substitute the puppy + adult dog = x
25 + 80 = x
105 = x
So, the final answer is $105.

бу – 8 = 2(3y – 4)
Is it no solution if it’s not what’s the answer
Answer:
All real numbers.
Step-by-step explanation:
So we have the equation:
[tex]6y-8=2(3y-4)[/tex]
First, distribute the right side:
[tex]6y-8=6y-8[/tex]
As we can see, both expressions on both sides of the equation are the exact same. In other words, every value of y will make the equation true. Thus, the answer is all real numbers.
Answer:
infinite solutions
Step-by-step explanation:
1 solution means that only 1 number can replace that variable
No solution means that no numbers can replace that variable. If the 2 sides of the question cannot be solved or they are different, then that equation has no solutions.
Infinite solution means that any number can replace that variable. If the 2 sides of the equation the same, then it is an infinite solution.
6y - 8 = 2(3y - 4)
=> 6y - 8 = 6y - 8
Since both sides of the equations are the same, "y" can be any number.
So, this equation has infinite solutions.

Can someone show me step by step how to solve this problem? I’m stuck on how to do this. 5/6x +3 > -7 (1/6x +3)
Answer:
x>-12
Step-by-step explanation:
first you would simplify by multiplying -7 from the terms in the parenthesis and then you would get [tex]\frac{5x}{6} +3>\frac{-7x}{6} -21[/tex] then you would add 21 to both sides to get rid of the -21 and you would get [tex]\frac{5x}{6} +24>\frac{-7x}{6}[/tex] then you would subtract 5/6 from both sides to get rid of the 5/6 so you get 24>[tex]\frac{-12x}{6}[/tex] and then you would simplify by multiplying 6 to both sides so you get 144>-12x then you would divide both sides by -12 (note that you have to flip the greater than or less then sign after dividing by a negative number) so you get -12<x or x>-12
Suppose you run 5 miles from your house to a friend's house at a speed of 6 miles per hour. When the time comes to return home, you are tired and walk the same 5 miles home at 3 miles per hour. How long did you spend running to your friend's house?
Answer:
2hours and 30minutes
Step-by-step explanation:
6mph for 5 miles, would be 10 minutes per mile(in an hour because of 60). Only five were completed to itd take 50 minutes. 3mph for 5hours would take 1hr and 40 minutes because 3miles would take 1 hour which would make one mile take 20 minutes so you add the two twenties(for the last two miles) to get 40. Then u add them together. (50min+60min+40min)

Write the equation of a line with a slope of 3 and passes through the point (-1,-8). Show steps please
Answer:
y = 3x-5
Step-by-step explanation:
[tex](-1,-8) = (x_1,y_1) \\ m = 3[/tex]
Substitute values into point slope form
[tex]y - y_1 = m(x - x_1) \\ y - ( - 8)) = 3(x - ( - 1)) \\ y + 8 = 3(x + 1) \\ y + 8 = 3x + 3[/tex]
[tex]y = 3x + 3 - 8 \\ y = 3x - 5[/tex]
Answer:
y=3x-5
Step-by-step explanation:
We are given a point and a slope, so we can use the point-slope formula.
[tex]y-y_{1}=m(x-x_{1})[/tex]
where m is the slope and (x₁, y₁) is the point.
The slope is 3 and the point given is (-1,-8). Therefore,
[tex]m=3 \\x_{1} =-1\\y_{1}=-8[/tex]
Substitute the values into the formula.
[tex]y-y_{1}=m(x-x_{1})[/tex]
[tex]y--8=3(x- -1)[/tex]
Simplify the signs. Two negative signs become a positive sign.
[tex]y+8=3(x+1)[/tex]
Distribute the 3. Multiply each term inside the parentheses by 3.
[tex]y+8= (3*x)+(3*1)[/tex]
[tex]y+8=3x+3[/tex]
We want to find the equation in slope-intercept form: y=mx+b. Therefore, we must isolate y. 8 is being added to y. The inverse of addition is subtraction. Subtract 8 from both sides.
[tex]y+8-8=3x+3-8[/tex]
[tex]y=3x+3-8[/tex]
[tex]y=3x-5[/tex]
The equation of the line is y=3x-5 ⇒ m= 3, b= -5

NEED HELP AND HOW U GOT THE ANSWER PLEASE find the measure of the angle greater than BXC using the figure below
Answer:
m∠BXC = 30°
Step-by-step explanation:
The symbol ∠ means "angle", so "angle ∠BXC" is actually redundant. The "greater than" symbol is "<", which sometimes is used when the proper angle symbol is not available.
Here, the question is simply asking for the measure of angle BXC.
Ray BX crosses the outer, inner scales of the protractor at 40, 140. Ray CX crosses those scales at 70, 110. The measure of angle BXC in degrees is the difference between the numbers on the same scale:
70 -40 = 30 . . . using outer scale numbers
140 -110 = 30 . . . using inner scale numbers
The measure of angle BXC is 30°.

18. A sum of money was shared among
Okpala, Olu and Bello such that
Okpala had one sixth of the money.
Olu had one quarter of the money
and Bello had the rest. By what
fraction of the money is Bello's share
greater than Okpala's and Olu's
shares put together?
Answer is something I’m not sure of
Bello's share is greater than Okpala's and Olu's shares combined by a fraction of 1/6 of the total sum of money.
Here, we have,
Let's assign variables to represent the shares of Okpala, Olu, and Bello.
Let M be the total sum of money.
Okpala's share = (1/6)M
Olu's share = (1/4)M
Bello's share = M - Okpala's share - Olu's share
To find the fraction of the money by which Bello's share is greater than Okpala's and Olu's shares put together, we need to calculate the difference between Bello's share and the sum of Okpala's and Olu's shares, and then express it as a fraction of the total sum of money M.
Bello's share - (Okpala's share + Olu's share) = (M - Okpala's share - Olu's share) - (Okpala's share + Olu's share)
= M - Okpala's share - Olu's share - Okpala's share - Olu's share
= M - 2(Okpala's share) - 2(Olu's share)
= M - 2[(1/6)M] - 2[(1/4)M]
= M - (1/3)M - (1/2)M
= M - (2/6)M - (3/6)M
= M - (5/6)M
= (1/6)M
Now, let's express this difference as a fraction of the total sum of money M:
Fraction of Bello's share greater than Okpala's and Olu's shares
= [(1/6)M] / M
= (1/6)
Therefore, Bello's share is greater than Okpala's and Olu's shares combined by a fraction of 1/6 of the total sum of money.
