They both weigh the same. They are both a pound each. One rock may weigh a pound where a thousand feathers may weigh a pound, but they still are both the amount needed to be a pound each. <span />
Answer:
45 and 135degrees
Step-by-step explanation:
Cos(8x+21)=sin(-2x+51) Find the two angles represented in degrees ??? Someone help its 1am I can't do this
In trigonometry, cosx = sin(90-x)
Hence:
Cos(8x+21) = sin(90-(8x+21))
Cos(8x+21) = sin(90-8x-21)
Cos(8x+21) = sin(-8x+69)
Substituting into the expression given, :
sin(-8x+69) = sin(-2x+51)
-8x+69 = -2x+51
-8x+2x = 51-69.
-6x = -18.
X = 18/6
X = 3
Since the angles 8x+21
Angle = 8(3)+21
Angle = 45
The angles represented in degrees are 45 and (180-45) = 135degrees
Answer:
A = 154 ft^2
Step-by-step explanation:
To find the area of a circle
A = pi r^2
The radius is 7 and pi = 22/7
A = 22/7 * 7^2
A = 154 ft^2
Answer:
Each of the 5 children receive one fifteenth pie
Step-by-step explanation:
Given:
One third of a pie shared equally between 5 children.
To find:
Amount of the pie with each of the 5 children.
Solution:
Number of children = 5
Also, one third of a pie shared equally between 5 children.
So,
Amount of the pie with each of the 5 children

Hence, each of the 5 children receive one fifteenth pie.
About 172 centimeters tall.
Since he is about 3/4 his average adult height, you simply divide his current height by .75
129/.75 = 172
