Answer:
I have no idea what this means
Answer: 28.275cm^3
Step-by-step explanation: The density equation is mass/volume, and you can rearrange the equation to figure out what the volume is. By rearanging the equation, you get that volume= mass/ density. So 11.31/0.40=28.275cm^3
<em>Answer:</em>
<em>Answer:3.33 </em>
<em>Answer:3.33 Step-by-step explanation:</em>
<em>The</em><em> </em><em>answer</em><em> </em><em>is</em><em> </em><em>3.33</em>
<em>2</em><em>/</em><em>3</em><em> × </em><em>5</em><em> = 3.33</em>
The tree, bamboo pole and the ground will form a right triangle. the length of the pole is the hypotenuse of the right triangle form. so it can be solve using:
sin A = o / h
where A is the angle
o is the oposite side of the angle
h is the hypotenuse
h = o / sin a
h = 12.2 / sin 40
h = 18.7 m is length of the pole
Answer:
y =-5/4x +11/2
Step-by-step explanation:
First we need to find the slope of the line
4x-5y = 10
Solve for y
Subtract 4x from each side
4x-4x-5y =-4x-10
-5y = -4x-10
Divide by -5
-5y/-5 = -4x/-5 -10/-5
y = 4/5x +2
The slope is 4/5
The slope of a line that is perpendicular is the negative reciprocal
m perpendicular = - (5/4)
We know have a slope = -5/4 and a point (2,3)
We can use the point slope form of a line
y-y1 = m(x-x1)
y-3 = -5/4 (x-2)
Distribute
y-3 =-5/4x +10/4
Add 3 to each side
y-3+3 = -5/4 x +5/2 +3
Get a common denominator
y = -5/4x +5/2 +6/2
y =-5/4x +11/2
