Find the area of each regular polygon. Round your answer to the nearest tenth if necessary
Answers
Answer:
Step-by-step explanation:
13). Area of a square = (Side)²
= (BC)²
Since, diagonals of a square bisect each other at 90°,
ΔBOC is a right triangle.
By applying Pythagoras theorem in the given triangle,
BC² = OB² + OC²
BC² = 2(OB)²
BC² = 2(7√2)²
BC = [tex]\sqrt{196}[/tex]
Area of square ABCD = (BC)²
= (√196)²
= 196 units²
14). Measure of interior angles of the regular hexagon = 120°
Area of the regular hexagon = [tex]\frac{3\sqrt{3}}{2}(\text{side})^2[/tex]
From the given picture,
m∠BAC = m∠ABC = m∠ACB = 60°
Therefore, ΔABC is an isosceles triangle.
And all sides of this triangle will be equal in measure.
AB = AC = BC = 9 units
Area of the given regular hexagon = [tex]\frac{3\sqrt{3}}{2}(9)^2[/tex]
= 210.44 square units
≈ 210.4 square units

Answer:
x=.5, y=-5.5
Step-by-step explanation:
7x+y=5, 7x+y=-2
Simplifing 7x+y=5 first
7x+y=5
y=-7x+5
Next, 7x+y=-2
7x+y=-2
y=-7x-2
Plugging in -7x+5 into y
-7x+5=-7x-2
-14x=-7
x=.5
Plugging .5 into y=-7x-2
y=-7(.5)-2
y=-3.5-2
y=-5.5
I used substitution if your couldn't tell

Find the probability that a randomly selected points within a square falls in the blue shaded area (circle)
Answers
Answer:
78.8 %
Step-by-step explanation:
From the question,
Area of the square = L²
A = L²
Where L = Length of the square.
From the diagram,
L = 4 in
Therefore,
A = 4²
A = 16 in².
Also,
Area of the circle (A') = πr²
Where r = radius of the circle.
Given: r = 2 in
Therefore,
A' = 22/7(2²)
A = 12.6 in²
Hence,
The probability that a randomly selected points within a square falls in the blue shaded area (Pr) = A'/A
Pr = 12.6/16
Pr = 0.7875
Pr(%) = 78.75
Pr(%) = 78.8 %

A school administrator claims that the average GPA of
the senior class is 3.53. You think that the average GPA
is greater than that, so you select a random sample of
100 seniors and calculate their average GPA. The
sample mean GPA is 3.70.
Using technology, you simulate selecting 100 SRS of
size n = 100 from a population of seniors for which the
mean GPA is 3.53. This dotplot shows the results.
O In one simulated SRS of 100 students, the average
GPA was = 3.45.
In one simulated SRS of 100 students, the
population mean GPA was u = 3.45.

mean GPA is = 3.45.

A 180 pound weight is supported by two ropes each at 30 degrees, as shown in the figure. Find the tension in each rope.
Answers
Answer:
= 41.32N
To find N amount
You find the kg weight then times it by 10 then divide that amount by 1/2
So that 180pounds = 81.6466 x 10kg
x10 = 816.466
81.6466 / 2 = 40.8233
sin(30) = 40.8233/T
T = 40.8233/sin (30) = N / sin(30) = Tension = calculator = -41.3178070464 = 41.32 N

Step-by-step explanation:
Using the pythagorean theorem A^2 + B^2 = C^2 the only numbers that work are those in choice B. 8 short leg, 15 long leg, 17 hypotenuse.
8^2 + 15^2 = 17^2 = 64 +225=289 = 289=289 therefor proving these set of numbers are a right triangle.
p-5 = 19
answer step by step & explain
Answers
Answer:
Step-by-step explanation:
Very simple.
p - 5 = 19
So to take out the -5 on that side, you must also do the same thing to the other side. So adding 5 in one side of the equal sign would mean you have to do the same thing on the other side of the equal sign.
SO:
p-5 +5 = 19+5
p = 24
26-5=19
(19+5 is also 26 so you can check your work that way)

Answers
Answer:
x = 3/5√10
y = 2√10
Step-by-step explanation:
using the Pythagorean theorem:
y² = 7² - 3² = 49 - 9
y² = 40
y = 2√10
3/4.5 = y/5x
4.5y = 15x
substitute for y:
4.5(2√10) = 15x
15x = 9√10
divide both sides of the equation by 15:
x = (9√10)/15 = 3/5√10
