Answer:
66 pieces of candy.
Step-by-step explanation:
First I set up the equation: (c/6)-4 = 7
c represents the candy she started with.
6 represent when she split the candy
4 is the number of pieces she has eaten
7 is the number of pieces she has left
after setting up the equation, you want to add four to the other side to get 11
c/6 = 7+4 --> c/6 = 11
Then you want to multiply by 6 to get ride of the fraction to get a total of 66 pieces of candy.
c = 11 x 6 --> c = 66
1250. Cubic feet = volume and volume is length * width * height. The volume of this would be 5x5x(1/2), which equals 12.5 cubic feet. 12.5*100=1250
Answer:
x= 20
Step-by-step explanation:
The sum of the three angles is 90 degrees
x+2x+x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10
4x+10-10 = 90-10
4x= 80
Divide by 4
4x/4=80/4
x = 20
Answer:
407.22 foot is the boat from the base of the lighthouse
Step-by-step explanation:
Given the statement: An observer on top of a 50-foot tall lighthouse sees a boat at a 7° angle of depression.
Let x foot be the distance of the object(boat) from the base of the lighthouse
Angle of depression = 
[Alternate angle]
In triangle CAB:
To find AB = x foot.
Using tangent ratio:
Here, BC = 50 foot and 
then;
or
Simplify:
AB = x = 407.217321 foot
Therefore, the boat from the base of the light house is, 407.22'
Answer:
The answer is <u>x = 2y</u>
Step-by-step explanation:
(3x + 2y) (3y + 2 y)
3x = 3y + 2y + 2y
3x = 7y
x = 7 ÷ 3
x = 2y
