Answer:
A. (a,0)
D. (a/2, b/2)
Step-by-step explanation:
Let's assume a and b means x and y coordinate if the x and y axes.
So the coordinates are now (0,0) ,(x,y) , (2x,0)
So all point from 0 to 2x lies on the sides of triangle
And all points from 0 to y lies on the
sides of the trianglee.
So we have three. Equation of the triangle .
One is x= y
So (a/2, b/2) is correct.
Second is 2x = 0y
So (a,0) is correct.
Answer:
- 1.25 hours or 1 hour and 15 minutes
Step-by-step explanation:
<em>Question</em>
- <em>Lisa lit a candle with a height of 8 inches. When lit, this candle loses 10% of its original height every hour. </em>
- <em>Please complete the following sentence by writing the number in the blank.
Until the candle has been burning for at least _______ hours, the height of Jennifer's candle will be more than 7 inches.</em>
<u>Candle looses 10% of 8 inches, it equals:</u>
- 8*0.1 = 0.8 inches an hour
<u>Let x be required time, then:</u>
- 8 - 0.8x > 7
- 0.8x < 8 - 7
- 0.8x < 1
- x < 1/0.8
- x < 1.25
- or 1 hour 15 minutes
Answer:
Step-by-step explanation:
Simplifying
f(x) = 800(0.85) * x
Multiply f * x
fx = 800(0.85) * x
Multiply 800 * 0.85
fx = 680x
Solving
fx = 680x
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = 680
Simplifying
f = 680
4/5
2(5x+4)=
distribute the 2
10x+8=
subtract 8 from both sides
10x=8
divide 10 from both sides
x=8/10
simplify by 2
x= 4/5
