The answer is <span>he lengths of the bases of the trapezoids are
trapezoid A
b=19cm, and B=35cm, b the short base and B the long base
trapezoid B
</span><span>b=19cm, and B=35cm, b the short base and B the long base
</span>
the height is h=15cm
the surface of A is A= hx(b+B) /2
so the surface is A= 15(19+35)/2=405cm²
we know that suface A =surfaceB, so Surface B= 405cm²
finally the total surface painted is 2 x 405cm²= 810cm²
the perimeter of the trapezoid A is PA=17+19+35+17=88cm
<span>the perimeter of the trapezoid B is PB=17+19+35+17=88cm
</span><span> one piece of sandpaper will not be enough to sand the edges of one trapezoid</span>
Answer:
no solution, 1/3x - 2 ≠ 1/3x + 3
where is the 'y'?
Step-by-step explanation:
Answer:
1 lb 4 oz of Ribeye for 4.99.
Step-by-step explanation:
1 ounce of Ribeye costs $0.25
1 ounce of filet Mignon costs $0.30
(There are 16 ounces per pound)
20 oz = 4.99 --> 4.99/20 = 0.2495
38 oz = 9.75 --> 9.75/38 = 0.2565789474
5. Slope intercept form is written as y = mx +b, where m is the slope and b is the y-intercept.
Using two of the points on the graph find the slope:
(0,-3) and (6,1)
Slope = change in Y over the change in X:
Slope = (1-(-3) / (6-0) = 4/6 = 2/3
The y-intercept is the Y value when x = 0, which is -3.
The formula is y = 2/3x - 3
6. Point slope form is written as y - y1 = m(x- x1) where m is the slope, y1 and x1 are a known point on the line.
Slope = (1-0) / (1-3) = 1/-3 = -1/3
You can use either point shown for x1 and y1, so I am using the point (1,1)
The equation becomes y -1 = -1/3(x-1)
