Step-by-step explanation:
The formula of an area of a trapezoid:
b₁, b₂ - bases
h - height
We have
b₁ = 12m , b₂ = 6.4 m, h = 5x m.
Substitute:
Answer:
slope: 0.75
Step-by-step explanation:
y = 0.5x + 2
or
y =
1/2x+2
When x=0, y = 2
When y=0, x = -4
Answer:
Step-by-step explanation: the discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.
We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.
0.2x = 3
Divide both sides by 0.2.
x = 3/0.2
x = 15
The regular price is $15.
Answer:
<em>Draw a circle of some radius. Divide the central angle (360 deg) into 6 equal parts of 60 each by a protractor. Join the points where the lines dividing the angle meets the circumference of the circle.</em>
Step-by-step explanation:
Six sides have the same length and the angles formed by six intersections of lines are correct. If either side has a length different from any other side, or if any of the angles differs from any other, it is not correct.
