Answer:15.8
Step-by-step explanation:
After 15.81 seconds the hammer reaches the river if the construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
A construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.
The equation is:
t = √h/4
Plug h = 4000 ft
t = √4000/4
After solving:
t = 15.81 seconds
Thus, after 15.81 seconds the hammer reaches the river if the construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.

2. Charlie has a collection of marbles in three sizes, small, medium, and large. He has four times as
many small marbles as medium marbles. The number of large marbles is three more than five times
the number of medium marbles.
a. Write algebraic expressions to represent the number of small marbles, medium marbles, and
large marbles Charlie has. Write algebrauc expressions to represebt the number of small marbles, medium marbles, and large marbles charlie has.
Answer:
Step-by-step explanation:
The required expression represents the number of the small marbles, medium marbles, and large marbles are m = 4s and l = 3 + 5m.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
Let the number of small marbles be s, medium marbles are m and large marble is l.
According to the question,
He has four times as many small marbles as medium marbles. The number of large marbles is three more than five times the number of medium marbles.
m = 4s
and
l = 3 + 5m
Thus, the required expression represents the number of the small marbles, medium marbles, and large marbles are m = 4s and l = 3 + 5m.

The second hand on Mr. Vidler's Alarm Clock is 6 cm long. Approximately how far does the tip travel in 5 minutes and 15 seconds? [Round your answer to the nearest tenth. Only type in the number, no units.]
Answer:
3.28 cm
Step-by-step explanation:
The calculation is given below:
we assume the following things
R denotes the radius of the circle
And, A denotes An arc
Now , the length of the arc is
L = (A ÷ 360°) × 2 × 3.14 × R
According to the question
R = 6 cm
Angle = 5 minutes and 15 seconds
The clock could complete its revolution in 60 minutes
Therefore
60 minutes = 360°
Also
1 min = 60 seconds
So
1 seconds = 1min ÷ 60seconds
Now for 15 seconds it is
= 15 seconds × (1 ÷ 60)
= (15 ÷ 60) min
= 0.25 min
And for 5 minutes and 15 seconds, it is
= 5 min + 0.25 min
= 5.25 min
Also
60 minutes = 360°
So,
1 minute = 360° ÷ 60min
Now For 5.25min
= (5.25min) × (360° ÷ 60min)
= 31.5°
Finally the length would be
L = (31.5° ÷ 360°) × 2 × 3.14 × 6cm
= 3.28 cm

Answer: where is the line segment
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The angles of a triangle add up to 180 degrees.
The second angle is 20 degrees larger than the smallest angle.
The third angle is 3 times as big as the smallest angle.
Find the measure of the smallest angle (in degrees)
Answer: 32 degrees
Step-by-step explanation:
small angle : x
middle angle: x + 20
large angle: 3x
Form an equation: 5x + 20 = 180
5x = 180 - 20
5x = 160
x = 160/5
x = 32

If 4x- 7 = 2x, then 2x = ?
If [tex]4x-7=2x[/tex], then [tex]2x=7[/tex].
Hope this helps.
Answer:
7
Step-by-step explanation:
We solve for x first.
So: 4x - 7 = 2x
Subtract 2x from both sides: 4x - 2x - 7 = 2x - 2x
2x - 7 = 0
Add 7 to both sides: 2x - 7 + 7 = 0 + 7
2x = 7
Divide by 2: [tex]\frac{2x}{2}[/tex] = [tex]\frac{7}{2}[/tex]
x = [tex]\frac{7}{2}[/tex]
Now, we substitute x for [tex]\frac{7}{2}[/tex] like this:
2 ( [tex]\frac{7}{2}[/tex]) = 7

18% of the the students at a school are in year 8 and 16% of the students are in year 9. If the school has 126 tera 8 students, determine the number of year 9 students.
Answer:
112
Step-by-step explanation:
The general form of all percentage questions is: the chunk= (some percentage) (of the whole), or c=p*w
We know that 18% of students are 8th grade and that is 126 students, so p = 0.18 and c=126 (126 students are 18% of the whole school)
126 = (0.18)w, divide both sides by 0.18
126/(0.18) = w = 700
9th graders are 16% of the school or 16% of 700 students
c = (0.16) 700 = 112 students
