Answer:

So the scaling means that per every foot in real life, you have 2.4 centimeters, which means that the scale model would be 48 cm tall.

A. To find your answer, you would divide 48 by 1.2, which is 40. So your model would be 40 bottle caps tall

B. Same as A, all you have to do is divide 48 by 15.2, which would be about 3 popsicle sticks tall (rounded)

(Hope this helps)

a gardenner is designing a new garden in the shape of a trapezoing she wants the short base to be twice the height and loger bas

taurus [48]

Answer:

Height = 5 ft

Short base = 10 ft

Long base = 14 ft

Step-by-step explanation:

Let h = height, a = short base, b = long base.

From the question,

a = 2h

b = a + 4 = 2h + 4

The area of the trapezoid is given by $\frac{1}{2}(a+b)h$ . Thus,

$60 = \frac{1}{2}(2h + 2h + 4)h$

$60 = \frac{(4h + 4)h }{2}$

$60 = \frac{4h(h + 1)}{2}$

$60 = 2h(h + 1)$

$30 = h(h + 1)$

$0 = h^2 + h - 30$

$0 = (h+6)(h-5)$

$h-5 = 0$ or $h+6 = 0$

$h= 5$ or $h = -6$

We discard the negative value of h since it is a measurement and cannot be negative.

$h= 5$

$a= 2h=2\times5=10$

$b= a+4=10+4=14$

Answer:

7 x 2/3 = 14/3 = 4 2/3

To find the area of a parallelogram, simply multiply the base times its height.
