I think the scale factor of one block to the arrangement would be 1/9, since the arrangement contains 9 blocks.

So if the length at the top is 12 cm, the length of the bottom of a trapezoid would be 12(1/9) = 4/3

Since we know that each trapezoid holds 3 equilateral triangles, the length of each side and the top of the trapezoidal would be 4/3 x 1/2 = 2/3 cm

The sum of the angles must equal 360 degrees, and because they are made of equilateral triangles, you know that each angle of the triangle must be 60 degrees. So the bottom two angles of the trapezoid are each 60 degrees, and the top two are 360- 120 = 240 divided by 2 angles = 120 degrees each.

pentagon [3]
All you need to do here is know where and how to plug in the numbers. In each equation, you'll have an initial fee, and an hourly fee, so your equation will be
y = i + hx, where i = the initial fee, and h = the hourly fee

So, after plugging them in, here's what you get:
Doors Galore: y = 40 + 50x

From a hot air balloon that is between his house and parade, john measures the angle of depression to his house of 35 and to the
igomit [66]

4500 feet

Step-by-step explanation:

We can begin by finding x using the tangent rule;

The tangent of the angle = the length of the opposite side / the length of the adjacent side

Tan 35 = 3500 / x

X = 3500 / tan 35

X  = 3500 / 0.7

X = 5000

Now that we have x we can calculate the value of ? using the same tangent rule;

Tan 42 = ? / 5000

? =  tan42 * 5000

? = 0.9 * 5000

? = 4500

Factor completely 50a2b5 − 35a4b3 + 5a3b4
Andreyy89

The complete factorisation of 50a²b⁵ − 35a⁴b³ + 5a³b⁴ is 5a²b³(10b² - 7a² + ab)

<h3>How to factorise?</h3>

Factorisation is the process of writing an expression as a product of two or more common factors.

The expression is written as a product of several factor.

Therefore,

50a²b⁵ − 35a⁴b³ + 5a³b⁴

Hence, the complete factorisation is as follows;

5a²b³(10b² - 7a² + ab)

There are eight furlongs in a mile and two weeks in a fortnight. If I travel 2800 furlongs in a fortnight, how many miles per da
katrin2010 [14]
Hello there! So, a fortnight is two weeks and two weeks is 14 days. You traveled 2,800 furlongs in two weeks. First off, let's divide the number of furlongs by the amount per mile. 2,800/8 is 350. That's 350 miles in two weeks. Now, we can divide 350 by 14 to find the amount traveled in 14 days. 350/14 is 25. There. You traveled 25 miles per day.
