Plzzz help me asap
Answer:
The geometric mean is the square root of 4*25
=10
Step-by-step explanation:
can someone please help me with this
Answer:
if the question is what is the are of the circle without the rectangle inside it, then we could solve it easily using the Mathematical formula for A Circle's area which is
[tex]\pi {r}^{2} [/tex]
since a radius is half a diameter, and the diameter is 8cm, the radius becomes 4 cm
Step-by-step explanation:
π×4^2

x = 60y = 70============================================
Explanation:
The parallel lines show that x = 60 since the 60 and the x angles are alternate interior angles. Alternate interior angles are congruent when we have parallel lines like this.
Focusing on the largest triangle, the three angles add to 180 degrees
x+y+50 = 180
60+y+50 = 180
y+110 = 180
y = 180-110
y = 70
This triangle appears to be equilateral, but it's not entirely so (it's fairly close however). That 50 degree angle in the bottom right corner would need to be 60 degrees for it to be equilateral.
How high can Ron lift a feather with his magic?
Answer: 705 cm
Step-by-step explanation:
Ron and Hermione are lifting feathers into the air with magic. Hermione can lift a feather 3,525
centimeters (cm) into the air. That is 5 times as high as Ron can lift a feather.
How high can Ron lift a feather with his magic?
Hermione = 3,525 cm
Hermione = 5 × Ron
Substitute Hermione = 3,525 cm into
Hermione = 5 × Ron
3,525 = 5 × Ron
Ron = 3,525 / 5
= 705
Ron = 705 cm

As the school’s sign language interpreter, Kiran gets paid $34 for every parent-teacher conference that he attends. He also gets paid $22 per school-related assembly that he attends as an interpreter. If Kiran earns $1008 for 36 paid events, how many parent-teacher conferences and how many school-related assemblies did he attend ?
Kiran atttended 18 parent-teacher conferences and 18 school-related assemblies.
Let x represent the number of parent-teacher conference and y represent the school-related assembly.
Since Kiran earns $1008 for 36 paid events, hence:
x + y = 36 (1)
34x + 22y = 1008 (2)
Solving equations 1 and 2 simultaneously gives:
x = 18, y = 18
Therefore Kiran atttended 18 parent-teacher conferences and 18 school-related assemblies.

What is the distance between W(3, 1) and X(-2,-5)? Round to the nearest tenth.
10
A. 61.0
B. 3.3
C. 2.2
D. 7.8
Answer:
D. 7.8
Step-by-step explanation:
Distance formula: [tex]\sqrt{(x_{2} - x_{1})^2 +( y_{2} - y_{1})^2 }[/tex]
Substituting (-2 - 3)² + (-5 - 1)²
Distance = [tex]\sqrt{(-5)^2 + (-6)^2}[/tex]
Distance = [tex]\sqrt{25 + 36}[/tex]
Distance = 7.8

please help with solving systtems of equation by graphing I'm lost
Answer:
Solution is (3, -3)
Step-by-step explanation:
To solve by graphing, you literally have to graph both lines to see where they intersect. That point of intersection is the solution to the given system.
Given the following linear equations:
y = - x where the slope (m) = -1, and the y-intercept (b) = 0.
y = x - 6 where the slope (m) = 1, and the y-intercept (b) = -6.
Plot the intercepts (0, 0) for the first line, and (0, -6) for the second line, as a starting point, then use the given slopes (rise over run) of each line to plot the next points. Repeat the process until you have enough points to connect with and create a line.
Attached is a screenshot of the graphed systems of linear equations. It shows that the solution is (3, -3).
