The geometric mean of 9 and 15
Answer:
[tex]\sqrt{135\\}[/tex]
Step-by-step explanation:
Geometric mean can be calculated like such:
a/x = x/b
Where a and b are your 2 numbers. By solving for x by cross-multiplying you get:
x^2=ab
So to solve for geometric mean, all you have to do is to multiply the two numbers and take the square root:
9(15)=135
[tex]\sqrt{135\\}[/tex]
The geometric mean of 9 and 15 is 11.62
Given two integers A and B, the geometric mean of the integers is expressed as:
GM = √A×B
Given the values 9 and 15, the geometric mean of the values is expressed as:
GM = √9×15
GM = √135
GM = 11.62
Hence the geometric mean of 9 and 15 is 11.62

Find m∟1 and m∟2. Tell which theorem can be use
Answer: Angle 1 = 150 - corresponding angles
Angle 2 = 150 - alternate exterior angles
Step-by-step explanation:
To find the measure of angles ∠1 and ∠2, we are using vertical angle theorem and corresponding angles concept.
From the given figure measure of one of the angle is 150°.
What are angles of parallel lines?Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.
Corresponding angles are angles that occur on the same side of the transversal line and are equal in size. They are either both obtuse or both acute.
Here, ∠1 = 150° (Corresponding angles)
∠1 =∠2 = 150° (Vertically opposite angles are congruent)
To find the measure of angles ∠1 and ∠2, we are using vertical angle theorem and corresponding angles concept.

Answer:
4. 380.13 cm²
5. 706.86 cm²
6. 12.57 cm²
Step-by-step explanation:
4. Area of circle = πr²
radius (r) = ½ of diameter = ½ of 22 cm = 11 cm
Area = π*11²
Area = 380.13 cm²
5. Area of circle = πr²
radius (r) = ½ of diameter = ½ of 30 cm = 15 cm
Area = π*15²
Area = 706.86 cm²
6. Area of circle = πr²
radius (r) = ½ of diameter = ½ of 4 cm = 2 cm
Area = π*2²
Area = 12.57 cm²
Grapes cost $2.70 per pound. You buy 2.5 pounds of grapes and give the cashier $10. How much change do you receive
Answer:
$3.25
Step-by-step explanation:
The grapes costs $2.70 per pound but you're buying 2.5 pounds so take $2.70 x 2.5 = $6.75. Now u just take $10 - $6.75 which equals $3.25 and thats ur answer.
Answer:
You receive 3.25 cash back.
Step-by-step explanation:
2.70 x 2.5 = 6.75
6.75 + ? = 10
A = 3.25
sin30=4/sqrt{3}/x
How to solve?
Answer:
[tex]x=\dfrac{8}{\sqrt3}[/tex]
Step-by-step explanation:
Given that,
[tex]\sin(30)=\dfrac{\dfrac{4}{\sqrt3}}{x}[/tex] ...(1)
We need to find the value of x.
We know that,
sin30 = 1/2
Use it in equation (1).
[tex]\dfrac{1}{2}=\dfrac{\dfrac{4}{\sqrt3}}{x}\\\\x=\dfrac{4}{\sqrt3}\times 2\\\\x=\dfrac{8}{\sqrt3}[/tex]
So, the value of x is equal to [tex]\dfrac{8}{\sqrt3}[/tex].

Step-by-step explanation:
A company manufactures a certain item and sells it online. The company has a business model where the cost C, in dollars, to make x items is given by the equation C=2.5x+21 and the revenue R, in dollars, made by selling x items is given by the equation R=6x. The break even point is the point where the cost and the revenue intersect. How many items must the company sell to break even?
Answer:
see the attachment
Step-by-step explanation:
The break-even point is on both curves. The y-intercept can be used for the other point in each case.
The break-even point is where cost and revenue are the same:
20/3x +50 = 10x
50 = 10/3x . . . . . . . . subtract 20/3x
15 = x . . . . . multiply by 3/10
r = c = 10(15) = 150 . . . . for x = 10
Two points you can use for graphing the lines are ...
cost: (0, 50) and (15, 150)
revenue: (0, 0) and (15, 150)

Theres a formula to figure this out. If you know two sides of a right angle triangle you can find the third.
Use the formula a²=b²+c², where a is the side opposite the right angle and b and c are the other sides.
a²=b²+c²
7²=2²+c²
49=4+c²

A military plane is flying directly toward an air traffic control tower, maintaining an altitude of 9 miles above the tower. The radar detects that the distance between the plane and the tower is 15 miles and that it is decreasing at a rate of 750mph. What is the ground speed of the plane
Answer:
-937.5 mph
Step-by-step explanation:
Assuming this takes place in a right angled triangle. With the hypotenuse side being, d, 15 miles, the opposite side being 9 miles and the adjacent being an unknown, x.
Using Pythagoras theorem, we know that
x² = 15² - 9²
x² = 225 - 81
x² = 144
x = √144
x = 12 miles.
Again, we should know that
2xx' = 2dd', this means that
xx' = dd'
From the question, we're told that it's decreasing at d' = 750 mph. On substituting, we have
x' = dd' / x
x' = (15 * -750) / 12
x' = -11250 / 12
x' = -937.5 mile per hour
The ground speed of the plane is also decreasing at 937.5 mile per hour

Step-by-step explanation:
Let us plug y into the equation:
6*1-3*1=
6-3=
3
I hope this helps! :)
Answer:
3
Step-by-step explanation:
you need to substitute the y for 1 because y=1
so it'll look something like this 6(1) - 3(1)
The y is touching the 6 and -3 so that means you need to multiply.
So 6(1) - 3(1) = 6-3 = 3
