Answer: arc ef is 68
Step-by-step explanation:
Since EF and FG are the same length (given)
and DE and DG are the same length (both are radius of the circle)
and DF is a shared side, the 2 inscribed triangles are congruent, making angle EDF also 68
The measure of an arc is the same as the measure of the angle across from it

A home value increases at a rate of 2.3% per year. If you purchased a home for 192,300, what would be the value of the home in 10 years? Round to the nearest cent.
Answers
9514 1404 393
Answer:
$241,399.09
Step-by-step explanation:
The value is increasing exponentially with a growth factor of 1.023, so it will be ...
v(t) = 192,300×1.023^t
v(10) = 192,300×1.023^10 ≈ 241,399.09
The value is predicted to be $241,399.09 in 10 years.

Answer:
x= 20,1 degrees
Step-by-step explanation:
The sum of the inner angles of a triangle is 180 degrees
So it must be
3x-11+6x-10+x = 180
added up the terms with x
10x -11-10 = 180
added up the terms without x
10x - 21 = 180
added up (21) in the two members of the equation
10x-21+21 = 180+21
10x = 201
divide the two members by 10
x = 20,1 degrees

Does anyone know what the answer please!?????????
Answers
Answer:
-5<x<9
Step-by-step explanation:
Within a triangle, the greater an angle, the greater the length of opposite side. So, since we know that 42° gives an opposite side of 23, and (3x+15)° gives an opposite side of 21, (3x+15) must be less than 42:
3x+15<42
3x<27
x<9
We also know that the angle (3x+15)° cannot equal zero or less than zero. So find x when 3x+15=0, and note that our value for x must be greater than this:
3x+15=0
3x=-15
x=-5
so, -5<x
Put both parts together to get: -5<x<9

List the following rational numbers in order from least to greatest -1/2, 2.5, -8 1/4,
1 1/2,-1.5,3
Answers
Answer:
-8, -1.5, 1/2, 1/4, 1/2, 1, 2.5, 3
Step-by-step explanation:
Answer:
-8, -1.5 , -1/2 , 1/4 , 2.5, 3 , 11/2 (if is not 11/2 but 1 and 1/2) the answer is : -8, -1.5 , -1/2 , 1/4 , 1/2, 1 , 2.5, 3
Step-by-step explanation:
First of all we have to express the decimal numbers with a fraction
2.5 = 25/10 = 5/2
-1.5 = -15/10 = -3/2
now we have to express al numbers with a fraction with the same denominator. In this case the value that help us the most is 4
-1/2 = -2/4
5/2 = 10/4
-8 = -32/4
1/4 = 1/4
11/2 = 22/4
-3/2 = -6/4
3 = 12/4
now we have to check only the numerators for discover the order of the numbers. So from the least to the greatest we have:
-32/4 ; -6/4 ; -2/4 ; 1/4 ; 10/4 ; 12/4 ; 22/4
the final step is rewrite the original numbers in this order
-8, -1.5 , -1/2 , 1/4 , 2.5, 3 , 11/2

Identify the volume of a regular triangular pyramid with base edge length 14 ft and height 9 ft.
Answers
Answer:
The volume is 588 ft³
Step-by-step explanation:
[tex]v = a {}^{2} \frac{h}{3} = 14 {}^{2} \times \frac{9}{3} = 588[/tex]
Answer:
254.6 ft3 F
Step-by-step explanation:
To find the volume of the pyramid, first calculate the area of the base.
As the pyramid is the regular triangular pyramid, the base is an equilateral triangle.
To find the area of the equilateral triangle, calculate the length of the height.
Since the triangle is equilateral, each angle in the triangle equals 60°.
The height forms a 30°- 60°- 90° triangle. One leg of this triangle is equal to half of the side of the large triangle, or 7 ft. The other leg of the triangle is equal to 73‾√ ft by the 30°- 60°- 90° Triangle Theorem.
Therefore, the length of the height of the triangle is 73‾√ ft.
To find the area of the base of the pyramid, B, use the formula for the area of a triangle, B=12bh.
Substitute 14 for b and 73‾√ for h.
B=12⋅14⋅73‾√
Simplify.
B=493‾√ ft2
To find the volume of the pyramid, use the formula for the volume of a pyramid, V=13Bh.
Substitute 493‾√ for B and 9 for h.
V=13⋅493‾√⋅9
Simplify.
V=1473‾√
Use a calculator to approximate.
V≈254.6 ft3
Therefore, the volume of the regular triangular pyramid is about 254.6 ft3.
