Answer: [(3/4)π] in² or (0.75π) in²
Step-by-step explanation:
Here, we are asked to find the area of a sector. So we are going to use the formula: A=πr²(θ/360)
--------------------------------------------------------------
Given
r=3 in
θ=30°
Solve
A=πr²(θ/360)
A=π(3)²(30/360)
A=9π(1/12)
A=[(3/4)π] in²
A=(0.75π) in²
Hope this helps!! :)

Find the approximate length of the line AB PLZZZZZZZZZZZZZZZZZZ HELPPPPPP
Answer:
Approximate length of line AB is 8.6
Step-by-step explanation:
Input Data :
Point 1 (xA, yA) = (8, 2)
Point 2 (xB, yB) = (3, 9)
Objective :
Find the distance between two given points on a line?
Formula :
Distance between two points = √(xB − xA) ^2 + (yB − yA)^2
Solution :
Distance between two points = √(3 − 8) ^2 + (9 − 2) ^2
= √(−5) ^2 + 7^2
= √25 + 49
= √74
= 8.6023
Distance between points (8, 2) and (3, 9) is 8.6023
hope this helps and is right :)
Answer:
First choice
12.0
Step-by-step explanation:
Make a right triangle, drawing straight lines, down from point A and left from point B. Use the pythagorean theorum to solve.
I will use "x," "y," and "z" as sides of the triangle as to not confuse between points a and b.
Line AB is line z
x^2 + y^2 = z^2
8^2 + 9^2 = z^2
64 + 81 = z^2
145 = z^2
(find square roots of both)
12.0416 = z
please look at picture. i will give brainliest to the correct answer!!!

Suppose WX = 4x - 8 and WZ = 2x + 2. Solve for x
Answer: 5
Step-by-step explanation:
Because the shape is a kite we can tell that WX and WZ are congruent.
So 4x-8 = 2x+2
Add 8 to both sides
4x = 2x+10
Subtract 2x
2x = 10
Divide by 2
x = 5
A national study report released by the Center for Studying Health System Change (HSC) in 2010, indicated that 20.9% of Americans were identified as having medical bill financial issues. Many people in families with problems paying medical bills in 2010 experienced severe financial consequences from their medical debt, with about two-thirds reporting problems paying for other necessities and a quarter considering bankruptcy, the study found. What if a news organization randomly sampled 400 Americans from 10 cities and found that 90 reported having such difficulty. A test was done to investigate whether the problem is more severe among these cities. The result of this test is ________.
Answer:
The result of this test is 0.2156
Step-by-step explanation:
Given the data in the question;
The proportion of Americans having medical bill financial issues is ;
p = 20.9% = 0.209
CLAIM;
The problem is more severe among the cities
so
H₀ : p = 0.209
H₁ : p > 0.209 { this is our claim }
population n = 400
number of people that reported difficulty x = 90
so
sample proportion p" = x / n = 90 / 40 = 0.225
Test Statistics;
z = [ (p"-p) / √( (p(1-p))/n ) ]
we substitute
z = [ (0.225 - 0.209) / √( (0.209(1-0.209)) / 400 ) ]
z = [ 0.016 / √0.0004132976 ]
z = [ 0.016 / 0.0203297 ]
z = 0.787
P-VALUE
p-value = P( Z ≥ z )
p-value = P( Z ≥ 0.787 )
p-value = P( Z ≤ -0.787 )
from normal distribution table;
p-value = P( Z ≤ -0.787 ) = 0.2156
p-value = 0.2156
Therefore, The result of this test is 0.2156
Triangle G F E is cut by line segment H J. Line segment H J goes from side G E to F E. The length of G F is 4 x minus 4, the length of H J is x + 3, and the length of J E is x minus 1.
If H is the midpoint of GE and J is the midpoint of FE, determine the following lengths.
HJ =
JE =
Answer:
HJ = 8 JE = 4
Step-by-step explanation:
it is given that H is the midpoint of GE and J is the midpoint of FE. According to the midpoint theorem the line segment connecting the midpoint of two sides is parallel to the three side and its length is half of the third side. since JH is connecting the midpoints.
HJ= 1/2 (GF)
x + 3 = 1/2 (4x - 4)
x + 3 = 2x - 2
x = 5
^ Thus meaning the value of x is 5.
Now you just fill into your equations:
HJ = x + 3 = (5) + 3 = 8
JE = x - 1 = (5) - 1 = 4
Therefore, HJ = 8; JE = 4.
Answer:
HJ = 8
JE = 4
Step-by-step explanation:

Find the area of a triangle
Answer:
B.17.5cm²
Step-by-step explanation:
S=a+b+c/2=
5+8+7/2=10
S=10
Area of the triangle=[tex]\sqrt{3(5-a)(5-b)(5-c)}[/tex]
⇒[tex]\sqrt{10(10-5)(10-8)(10-7)}[/tex]
⇒[tex]\sqrt{10*5*2*3}[/tex]
⇒[tex]\sqrt{300}[/tex]
⇒17.5cm²

If the radius of a circle is 3, calculate the diameter.
also can anyone please explain how to do this? i would really appreciate it.
Answer:
The diameter would be 6
Step-by-step explanation:
the radius is half of a diameter, so you would have to double the radius to get the diameter
d=2r
=2(3)
=6
The diameter reaches across the circle, while the radius reaches only half way, so you would have to double the radius to get the diameter (2r)
sorry if this doesnt make sense

A certain drug is made from only two ingredients: compound A and compound B. There are 3 milliliters of compound A used for every 4 milliliters of compound B. If a chemist wants to make 378 milliliters of the drug, how many milliliters of compound B are needed?
Answer:
216 milliliters
Step-by-step explanation:
Since, there are 3 milliliters of compound A used for every 4 milliliters of compound B.
Therefore,
A : B = 3 : 4
Let the common multiplier of the given ratios be x.
So, A = 3x & B = 4x
Since, chemist wants to make 378 milliliters of the drug.
Therefore, total volume of drug = 378 milliliters.
3x + 4x = 378
7x = 378
x = 378/7
x = 54
4x = 4*54 = 216
Thus, 216 milliliters of compound B are needed.

How can you determine the part of an hour that is 15 minutes?
Answer:
You'll need to convert the minutes part to hours. 15 minutes times 1 hour per 60 minutes will make the conversion to hours and minutes will cancel out. 0.25 hours times 60 minutes per 1 hour = 0.25 hr × (60 min/ 1hr) = (0.25 × 60) min = 15 minutes.
Step-by-step explanation:
Helllpppppppppppp fast this
Answer:
None of he choices are correct. Now before you say I'm wrong, look at any one of the unknown angles. You can plainly see that they each are greater than 90 °.
x = 120°
Step-by-step explanation:
5 sides
(180 x 5) - 360 = 540° total of interior angles
540 - 90 - 90 = 360° total for the 3 unknown angles
x = 360/3 = 120°
