Answer:
Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene, isosceles, equilateral and so on.
The triangle inequality property states that the sum of any two sides of a triangle must be greater than the third side. If a, b and c are the sides of a triangle then:
a + b > c; a + c > b; b + c > a
Given a triangle with side length 4 m, 8 m, 9 m:
4m + 8m = 12m > 9m
4m + 9m = 13m > 8m
8m + 9m = 17m > 4m
Therefore a triangle can be formed with side lengths of 4 m, 8 m, 9 m.

Lindsey and Justin want to collect data to find out the favorite afterschool activities of 7th grade students at Schofield Middle School. Which
group of people should Lindsay and Justin survey to achieve the most accurate results?
A: all of the students in band.
B: a random selection of two girls and two boys for each 7th grade class.
C: a random selection of two girls and two boys from the chess club.
Lindsey and Justin must survey a random selection of two girls and two boys for each 7th grade class to get the most accurate results, so the correct choice is B.
StatisticsThis is so because, since precise information is required regarding a particular group of students (7th graders), it would be correct to target members of that group to obtain the first samples of information.
That is, by going to the most reliable source, a more reliable sample would be obtained.

A search and rescue drone can scan 0.5 hectare in 2 minutes. How many hectares per minute can the drone scan? 5/10 ha | 2 min = 5/10×2/1 yes or no
Answer:
Drone will take 0.25 hectare per minute to scan the area.
Step-by-step explanation:
By using unitary method,
A search and rescue drone takes 2 minutes to scan the area = 0.5 hectare.
Area scanned by the drone in 1 minute = [tex]\frac{\text{Total area scanned}}{\text{Total time taken}}[/tex]
= [tex]\frac{0.5}{2}[/tex]
= 0.25 hectare per minute
Therefore, drone will take 0.25 hectare per minute to scan the area.

Answer:
x=3
Step-by-step explanation:
First would need to convert the radical into a number.
And since if you have a perfect square of a radical it goes outside the square root sign, you would take the 3 and square it to make 9 and then take the 2 inside the square root sign and multiply so you have the square root of 18|
Since we have [tex]\sqrt{18}[/tex] as the Leg c we would need to square it, squaring a square root sign would just cause them to be cancelled out and you being left with 18, afterwards find the square of 3, which is 9
18-9=9
square root of 9 = 3

The value of n in terms of x.
Solution:
We have,

It can be written as

Find the measure of each angle in the isosceles trapezoid.
(I found one already)
Answer:
∠A = 116°
∠B = 116°
∠C = 64°
Step-by-step explanation:
since it is an isosceles trapezoid, ∠C = ∠D = 64°
∠A would be same side interior to ∠D so it would be 180° - 64° = 116°
∠B = ∠A = 116°
The measure of each angle in the isosceles trapezoid are; ∠A = 116°
∠B = 116° and ∠C = 64°
What is isosceles trapezoid?Due to the figure being isosceles trapezoid, it is symmetric.
Isosceles trapezoid has its two rest sides(which aren't necessary parallel) are of equal length.
Since it is an isosceles trapezoid, ∠C = ∠D = 64°
Here we can use the symmetric property of the isosceles trapezoid and the fact that a triangle has sum of its angles as 180°
We have ∠A that would be same side interior to ∠D
Thus, it would be 180° - 64° = 116°
∠B = ∠A = 116°

What is a downside of receiving a tax refund?
Tax returns aren't gifts. They're refunds you get because the IRS withdrew too much from your paychecks or had withdrawals from other investment accounts. While it may seem like a great thing to have a tax return come each April, you pay for it the other 11 months of the year.
“A refund means you're giving your cash flow and income to the government in an interest-free loan.” The interest rate on one-year U.S. bonds is around 1.5%, so any interest the government could hypothetically pay on that loan would be very small: about $15 for every $1,000 in your refund.

Determinant of the coefficient matrix from online determinant calculator is;
D = 136
Determinant of the x-matrix from online determinant calculator is; Dx = 92
Determinant of the y-matrix from online determinant calculator is; Dy = 696
Determinant of the z-matrix from online determinant calculator is; Dz = 576
From crammers rule;
x = Dx/D = 92/136
y = Dy/D = 696/136
z = Dz/D = 576/136
During a walk-a-thon, Noah's time in hours, t, and distance in miles, d, are related by the equation ⅓ d = t. A graph of the equation includes the point (12, 4). Identify the independent variable. What does the point (12, 4) represent in this situation? What point would represent the time it took to walk 7 ½ miles?
Answer:
The Indapendent virable is: t
Noah took 4 hours to walk 12 miles
(7 1/2, 2 1/2)
Step-by-step explanation:
I hope this is right!
The point that represents the time it took to walk 7 ½ miles is (2.5, 7.5).
What is coordinate?Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.
Here,
The independent variable in this situation is time (t).
Point (12, 4) represents that Noah walked for 4 miles in 12 hours.
To find the point that represents the time it took to walk 7 ½ miles, we need to solve for t in the equation ⅓ d = t.
Substituting d = 7.5, we get:
⅓ (7.5) = t
Simplifying, we get:
t = 2.5
Therefore, the point that represents the time it took to walk 7 ½ miles is (2.5, 7.5).

Answer:
22,000 miles
Step-by-step explanation:
Circumference of a circle: 2πr (r is the radius)
Substitute the length of the radius given, which is 3500. Also, substitute the approximate value of π, which is 3.14.
Circumference = 2 * 3.14 * 3500
Circumference = 21980
This rounds to about 22,000, so the answer is 22,000 miles.
I hope this helps! Feel free to ask any questions!
Answer: 22,000 miles
Step-by-step explanation:
Circumference of circle = 2πr
2 × 22/7 × 3500
22/7 × 3500 = 11000
2 × 11000 = 22000
The circumference would be 22,000 miles.
OR
Circumference of circle = 2πr
2 × 3.14 × 3500
6.28 × 3500 = 21,980
21980 to the nearest 1000 is 22000
The circumference would be approximately 22,000 miles.
