Answer:
17.078 square units
Step-by-step explanation:
The area of a segment is given by the formula ...
A = 1/2r²(θ -sin(θ)) . . . . where θ is in radians
The angle θ is 48°, or π(48°/180°) radians = 4π/15 radians.
Then the segment area is ...
A = (1/2)(19²)(4π/15 -sin(48°)) = 17.078 . . . square units

Answer:
1400
Step-by-step explanation:
two ways to do this
1, find the area of the shaded place.
2, find the area of the whole thing, subtract by the area of the corners.
this way is easier so its what ill do
whole box is 60*30=1800
3 corners are 10*10=100 15*10=150 and 15*10=150
1800-150-150-100 = 1400
or you could do it the first way
bigger box is 20*45=900
long box is 10*35=350
small box is 15*10=150
900+350+150=1400

8. The distance from Earth to the Sun is approximately 9 x 10^7 miles. The distance from Earth to the Moon is approximately 2x10^5 miles. Approximately how many times the distance from the Earth to the Moon is the distance from Earth to the Sun?
A. 450
B. 222
C. 45
D. 18
Answers
Answer:
A
Step-by-step explanation:
To find how many times the distance, we divide the distance to the sun by the distance to the moon.
we get:
(9 * 10^7) / (2 * 10^5)
First, lets isolate and simplify the powers of 10.
(9 /2) * (10^7/10^5)
(9/2) * (10^2)=(9/2) * 100
Solve
9/2*100=4.5*100=450

isosceles triangle?
Answers
Answer:
112º and 73º
Step-by-step explanation:
34º could be base angle
Base angles are equivalent
Vertical angle would be = 180 - 34 - 34
Vertical angle = 112º
34º could be vertical angle
Base angles are equivalent
2x = 180 - 34
Base angle = 73º

Answers
Answer:
52 Hz
Step-by-step explanation:
We can divide the speed by the wavelength to find the number of waves propagated in one second:
(130 m/s)/(2.5 m/wave) = 52 waves/s
The SI unit of frequency is the Hertz, equal to one cycle per second.
The frequency of this wave is 52 Hz.

Additional comment
The use of the unit Hz to signify frequency was adopted in 1933, but did not replace the unit "cycles per second" (CPS) until a number of years later.

Y=2.5x
y= x - 4
Answers
Answer:
y=2.5x - Proportional
y= x - 4 - Not Proportional
Step-by-step explanation:
A linear function that is proportional is in the form y =kx (k is the constant of variation) and passes the origin.
The first equation given is in this form (2.5 is the constant) and it passes through the origin. It is proportional.
However, the second one is not proportional is it does not pass the orgin and it's not in y=kx form.
Hope this helps.

Answer:
x = 50 and y = 10
Step-by-step explanation:
The drawing shows several equal sides. The triangles are a reflection of each other, so their angles will be the same.
Take the top and bottom angles:
2x + 5 and 3x - 45
They are equal, so:
2x + 5 = 3x - 45
-x = -50
x = 50
The angle y will have the same value as the one below it in the bottom triangle. Add the angles in the lower triangle and since the sum of the angles in a triangle is always 180, we can say:
y + (8y-15) + (3x-45) = 180
Rearrange:
y = 180 - (8y-15) - (3x-45)
y = 180 - 8y + 15 - 3x + 45
9y = 180 + 15 - 3x + 45
Since x = 50:
9y = 180 + 15 - 3*(50) + 45
9y = 180 + 15 - 150 + 45
9y = 90
y = 10

It takes 5 builders 3 1/2 hours to build a wall. How many hours will it take for 2 builders to build an identical wall?.
Answers
Answer:
8.75 hours for 2 builders so complete it
Step-by-step explanation:
its right because im smart and i say its right
If it takes 5 builders [tex]3\frac{1}{2}[/tex] hours to build a wall, it will take 2 builders [tex]8\frac{3}{4}[/tex] hours to build an identical wall
The time taken for 5 builders to build the wall = [tex]3\frac{1}{2}[/tex] hours
The time take for 5 builders to build the wall = 3.5 hours
Time taken for 1 builder to build an identical wall =
5 x (Time taken for 5 builders to build the wall)
Time taken for 1 builder to build the wall = 5 x 3.5
Time taken for 1 builder to build the wall = 17.5 hours
Time taken for 2 builders to build an identical wall = (Time taken for 1 builder)/2
Time taken for 2 builders to build an identical wall = 17.5/2
Time taken for 2 builders to build an identical wall = 8.75 hours
Time taken for 2 builders to build an identical wall = [tex]8\frac{3}{4}[/tex] hours
