Amount of time spent by Nathan's family watching the video is 3/4 hour or 45 minutes.
What are Fractions?Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.
Here, a is called the numerator and b is called the denominator.
Given that,
Nathan’s family spent 2 and 1/4 hours visiting national monument near their home.
They watched a video in the visitor center for 1/3 of that time.
Total time spent by Nathan's family in the monument = 2 + 1/4 hours
= 9/4 hours
Fraction of time spend in watching the video = 1/3
Time spend in watching the video = 1/3 × 9/4
= 3/4 hour
= 45 minutes
Hence the time spent is 3/4 hour.

Step-by-step explanation: :)
You would first calculate the area of the base, which is length times width. You would then calculate the area of the faces, which is 1 2 (base times height) and multiply the result by 4 for the 4 faces. Finally, add the area of the base and the areas of the faces.

{f(x) ∈ ℝ | f(x) ≥ 3}
{f(x) ∈ ℝ | f(x) > 3}
{f(x) ∈ ℝ | f(x) < 3}
{f(x) ∈ ℝ | f(x) ≥ 3} is the range of f(x) = |x| + 3
⇒ Range is in the y-axisWhen graphing the following equation shown below:
f(x) ≥ 3f(x) ∈ ℝ[ 3, ∞ ]Answer:
{f(x) ∈ ℝ | f(x) ≥ 3}
Step-by-step explanation:
The range of a function is the output values (y-values).
Absolute value is the distance of x from zero, so it is never negative. It is denoted by a bar on either side of the term.
Therefore, as |x| ≥ 0 then |x| +3 ≥ 3
Therefore, the range of the function is {f(x) ∈ ℝ | f(x) ≥ 3}

Find the area of a regular octagon with an apothem length of 10 and a side length of 6.
Answer:
A = 240 units²
Step-by-step explanation:
the area (A) of a regular polygon is
A = [tex]\frac{1}{2}[/tex] pa ( p is the perimeter and a the apothem )
here p = 8 × 6 = 48 ( an octagon has 8 sides ) and a = 10 , then
A = [tex]\frac{1}{2}[/tex] × 48 × 10 = 24 × 10 = 240 units²
Answer:
Step-by-step explanation:
Preliminary task
Draw a regular octagon.
Draw a perpendicular from the side's midpoint to the center. (That is the apothem).
Draw two radii from the center of the side to the center of of the octagon. The endpoints of these two radii is the endpoints of the octagon's side.
The octagon has 8 such triangles.
Area one triangle
Area = 1/2 * side * apothem
side = 6
apothem = 10
Area = 1/2 6 * 10
Area = 30
Area of 8 such triangles.
Area = 8 * area of 1 triangle
area 1 triangle = 30
Area of 8 such triangles = 30*8 = 240

Henry has scored 30, 29, 22, and 21 points in his four basketball game so far. How many points does he need to score in his next game so that his average mean is 24 points per game
Answer:
20
Step-by-step explanation:
I think
sorry
The required Henry needs to score 18 points in his next game to have an average of 24 points per game.
What is mean?The mean of the values is the ratio of the total sum of values to the number of values.
Here,
average = sum of all scores/number of scores
We know that Henry has played four games so far, and his scores are 30, 29, 22, and 21 points. Therefore, the sum of his scores is:
sum of scores = 30 + 29 + 22 + 21 = 102
Let's assume that Henry scores x points in his next game. Then, his total score for all five games will be,
total score = 102 + x
If his average is 24 points per game, we can set up the equation:
24 = (102 + x) / 5
120 = 102 + x
x = 18
Therefore, Henry needs to score 18 points in his next game to have an average of 24 points per game.

Answer:
D) 30
Step-by-step explanation:
AB is the diameter of the circle
AB = AE + EB
= 25 + 9
= 34
OB, OC and OD are all the radius of the circle.
Radius = half the diameter
Therefore, OB = OC = OD = 34 ÷ 2 = 17
ΔCOD is an isosceles triangle with congruent sides OC and OD, and height OE
OE = OB - 9
= 17 - 9
= 8
Base of isosceles triangle = [tex]2\sqrt{a^2-h^2}[/tex]
(where a is one of the congruent side lengths and h is the height)
[tex]\implies CD=2\sqrt{OD^2-OE^2}[/tex]
[tex]\implies CD=2\sqrt{17^2-8^2}[/tex]
[tex]\implies CD=30[/tex]

The soccer players were required to run 6 more laps per day than the tennis players for five straight days. If the soccer players ran 45 laps total during these days, how many laps did the tennis players run each day?
Answer:
3 laps per day
Step-by-step explanation:
Divide 45 laps by 5 days to get how many laps they ran per day

The tennis players run 6 less laps per day than the soccer players so subtract 6 laps from 9 laps to get their daily laps
6-9 = 3 laps per day
