Answer:
16
Step-by-step explanation:
3/4y-7=5
*multiply both sides of the equation by 4
= 3y-28=20
*move <u>constant</u> to the right-hand side and change its sign
=3y=20+28
*add the numbers <u> </u>
=3y=48
*divide both numbers by 3
and that's how you get 16
Answer:
1595 ft^2
Step-by-step explanation:
The answer is obtained by adding the areas of sectors of several circles.
1. Think of the rope being vertical going up from the corner where it is tied. It goes up along the 10-ft side. Now think of the length of the rope being a radius of a circle, rotate it counterclockwise until it is horizontal and is on top of the bottom 20-ft side. That area is 3/4 of a circle of radius 24.5 ft.
2. With the rope in this position, along the bottom 20-ft side, 4.5 ft of the rope stick out the right side of the barn. That amount if rope allows for a 1/4 circle of 4.5-ft radius on the right side of the barn.
3. With the rope in the position of 1. above, vertical and along the 10-ft left side, 14.5 ft of rope extend past the barn's 10-ft left wall. That extra 14.5 ft of rope are now the radius of a 1/4 circle along the upper 20-ft wall.
The area is the sum of the areas described above in numbers 1., 2., and 3.
total area = area 1 + area 2 + area 3
area of circle = (pi)r^2
total area = 3/4 * (pi)(24.5 ft)^2 + 1/4 * (pi)(4.5 ft)^2 + 1/4 * (pi)(14.5 ft)^2
total area = 1414.31 ft^2 + 15.90 ft^2 + 165.13 ft^2
total area = 1595.34 ft^2
Answer:
What do you mean???
Step-by-step explanation:
21) Since all angles = 180,
180=66 + 79 + (43 + x)
Subtract (66 + 79) from both sides, you’d get
35= 43 + x
subtract 43 from both sides and x = -8
Answer:
B
Step-by-step explanation:
the frequency will change for each trial so a is wrong
b yea the probability should increase for either head or tail as the experiment progresses
c it will be impossible to get the frequency of head to equal the frequency of tails
d this is a 49/51 chance depending on what side did it flip on so while the frequency could increase the frequency could also decrease
the answer is B
I'm from your other question asking for help lmæo. and besides who flips that many coins
