Answer:
y- (0,2.5) x-(3.5,0)
Step-by-step explanation:
This is because the intercepts of a graph are the points at which a line intersects with a desired axis. So for the Y axis the inercept would be at 2.5 making the y intercept (0,2.5). The same concept is used on the X axis.
To solve the first question, the angles J and K are perpendicular to each other, that means also that the angles are 90 degrees.
Apart from each other.
This is the total angle measure, that means the sum of the smaller angles must equal 90 degrees.
So the expression would be
2x - 9 + 27 = 90
2x + 18 = 90
2x = 90 - 18
2x = 72
X = 72/2 = 36 degrees.
For the second question since w and v are parallel that means the angles are equal to each other
Thus make the expressions and value equal to each other and solve for x
3x + 60 = 120
3x = 60
X = 20 degrees.
The DJs unit rate is 5 songs for every 1 commercial.
I found this by dividing both the commercials and the songs by their greatest common factor, or 2.
Answer:
125 adults
175 children
Step-by-step explanation:
3900=8c+20a
300=c+a
c=300-a
substitute
3900=8(300-a)+20a
reduce
3900=2400-8a+20a
1500=12a
a=125 adults
substitute for a
c=300-a
c=300-125
c=175 children
If we have triangular pyramid with a side of s and all the faces and the base are equilateral triangles, then the formula for the total surface area is
SA = 3As + Ab
Where As is the area of the three faces
and
Ab is the area of the base
Since the triangles are equilateral, the surface area in terms of s is
SA = 3 (√3/ 4) s² + √3/ 4 s²
SA = √3 s²
