So the equation for a trapezoid is
, with the b variable being the 2 bases, h variable for height, and the a variable for area. Firstly, we will need to plug in the appropriate numbers into the equation, and it'll look like this:
Next, we will need to combine 12 and 14, then divide the sum by 2. Your equation should look like this:
Lastly, just divide each side by 13, and your answer should be
The answer is D. The nearest hundred thousand in this case would be 6 and the next number is 5 or more, we raise it up 1.
Answer:
y = 7x
Step-by-step explanation:
Complete question:
Find an equation for the line with the given properties. Parallel to the line 7x - y = -7; containing the point (0,0)
The equation of a line in point-slope form is expressed as;
y - y0 = m(x-x0)
(x0, y0) = (0,0)
Given the equation of the line as 7x - y = -7;
Rewrite and get the slope
-y = -7x - 7
y = 7x+7
Get the slope
mx = 7x
m = 7
Substitute into the equation
y - 0 = 7(x - 0)
y = 7x
Hence the required equation is y = 7x
<span>Let A be the center of a circle and two angles at the adjacent center AOB and BOC. Knowing the measure of the angle AOB = 120 and the measure BOC = 150, find the measures of the angles of the ABC triangle.
</span>solution
Given the above information;
AC=AB, therefore ABC is an isosceles triangle.
therefore, BAO=ABO=(180-120)/2=30
OAC=OCA=(180-90)/2=45
OBC=BCO=(180-150)/2=15
THUS;
BAC=BAO+OAC=45+30=75
ABC=OBA+CBO=15+30=45
ACB=ACO+BCO=15+45=60
