Let
x------> height of Leon's older brother
y------> height of Leon
Convert mixed number to an improper fraction
4\frac{3}{4}\ ft=\frac{4*4+3}{4}= \frac{19}{4}\ ft443 ft=44∗4+3=419 ft
we know that
x=\frac{19}{4}\ ftx=419 ft -----> equation A
y=x-\frac{1}{3}y=x−31 -----> equation B
substitute equation A in equation B
y=\frac{19}{4}-\frac{1}{3}=\frac{53}{12}\ fty=419−31=1253 ft
Convert to mixed number
\frac{53}{12}=\frac{48}{12}+\frac{5}{12}=4\frac{5}{12}\ ft1253=1248+125=4125 ft
therefore
the answer is
4\frac{5}{12}\ ft4125 ft

it is 200 km north and 50 east from the airport meaning it is 250 km away from the airport 100west and 50 north meaning it is 130 km away from the airport 130 + 250 = 380 km. 380 km is closest to 400 so D.
A science museum has an average of 424 visitors each day. The museum is open every day. Over a two-week period, how many people visit the museum?
Answer:
5936 people
Step-by-step explanation:
Answer: 5936 people visit the museum in an average of 2 weeks.
Step by Step Explanation:
There is 7 days in a week. To find the amount of day in two weeks multiply the number of days in a week by 2.
7x2=14
Next, multiply 424 by the number of days in two weeks.
424x14= 5936
The answer is, 5936 people visit the museum in an average of 2 weeks.

A tree is 4.1 feet tall. It is expected to grow by 14 feet per year.
At this growth rate, how many years will it take for the tree to have a height greater than 40 feet Enter the answer in th
Answer:
3 Years.
Step-by-step explanation:
4.1 feet = Starting Height.
4.1 + 14 feet = 18.1 feet.
18.1 + 14 feet = 32.1 feet
32.1 + 14 feet = 46.1
Count the number of times you added 14 to your number.
1, 2, 3.
It would take 3 years for the tree to have a height greater than 40 feet.
Answer:
It will take 3 years.
Step-by-step explanation:
To solve, we need the equation:
4.1+14x > 40.
x represents the number of years.
Then plug in numbers till we get above 40.
4.1+14(1) > 40.
4.1+14 > 40.
16.1 > 40.(incorrect)
4.1+14(2) > 40.
4.1+28 > 40.
32.1 > 40.(incorrect)
4.1+14(3) > 40.
4.1+42 > 40.
46.1 > 40.(correct)

Which expression is not equivalent to 8 + (n - 4)?
1. n + 4
2. (8 - 4) + n
3. (8 + n) - 4
4. 12 + n
Answer:
D. 12 + n
Step-by-step explanation:
To solve this question we have to simplify each equation 1 by 1 :
First, let us do the equation in the problem:
8 + (n - 4) = n +4
Now let us review the answers:
A. Is equivalent because 8 + (n - 4) = n + 4
B. Is equivalent because (8 - 4) + n = n + 4
C. Is equivalent because (8 + n) - 4 = n + 4
and D. is not equivalent because obviously 12 + n does not equal n + 4

A population has 75 observations. One class interval has a frequency of 15 observations. The relative frequency in this category is:
Answer:
The relative frequency in this category is 0.2
Step-by-step explanation:
The relative fraquency of a category is given by the number of observations in this category divided by the total number of observations.
In this question:
The category of interest has 15 observations.
In total, the population has 75 observations.
So the relative frequency is:
[tex]\frac{15}{75} = \frac{1}{5} = 0.2[/tex]

The diagram shows FGH, its medians, centroid P, and the lengths of some of the subsegments. Apply the Centroid Theorem to find other lengths.
Answer:
Step-by-step explanation:
We will use two properties to solve this problem,
1). Medians of a triangle bisect the sides of a triangle.
2). Centroid of a triangle divides the medians in the ratio of 2 : 1.
Length of FH = 2 × Length of HX
= 2 × 12
FH = 24
PF : PZ = 2 : 1
[tex]\frac{PF}{PZ}=\frac{2}{1}[/tex]
[tex]\frac{PF}{4}=\frac{2}{1}[/tex]
PF = 8
GX = GP + PX
GP = 9 [Given]
Since, [tex]\frac{GP}{PX}=\frac{2}{1}[/tex]
PX = [tex]\frac{9}{2}[/tex] = 4.5
Therefore, GX = 9 + 4.5
GX = 13.5
The other lengths using the centroid theorem gives us;
FH = 24
PF = 8
GX = 13.5
The centroid of a triangle is defined as the point where the three medians intersect each other.
Now, the centroid theorem states that the centroid is ²/₃ of the distance from each vertex to the midpoint of the opposite side.
Thus, applying the centroid theorem to the given triangle gives;
FH = 2(HX)
We see that HX = 12.
Thus; FH = 2 * 12
FH = 24
Also; PF = 2(PZ)
We see that; PZ = 4
Thus;
PF = 2(4)
PF = 8
Also, GP = 2(PX)
We have GP = 9.
Thus;
9 = 2(PX)
PX = 9/2
PX = 4.5
GX = GP + PX
GX = 9 + 4.5
GX = 13.5
