Answer:
x = 8
Step-by-step explanation:
==>Given that a family pool with a quadrilateral shape ABCD is similar with the dog pool EFGH, we can find the value of x by using the proportion of their corresponding sides.
Since ABCD ~ EFGH, the proportion of their corresponding sides are equal.
Thus, AB/EF = BC/FG = CD/GH = DA/HE
We have: 3/y = 4/3 = 5/z = x/6
Finding z:
4/3 = 5/z
Cross multiply
4*z = 5*3
4z = 15
z = 15/4
z = 3.75
Let's find x:
5/z = x/6
5/3.75 = x/6
Cross multiply
6*5 = x*3.75
30/3.75 = x
8 = x
x = 8
The way I answered this question is by putting it in a equal equation. If y and x are directly related then you can solve it by doing the following:
<u>
y</u> <u>15</u> = <u>y</u>
x 18 = 1.6
15* 1.6 = 18*y
<u>24</u> = <u>18y</u>
18 18
1.333333333 = y
1.3 = y
Answer:
2/3
Step-by-step explanation:
Given:
9⁴×12³×8 / 6⁴×4³×54
= (9⁴/6⁴) × (12³/4³) × (8/54)
= (9/6) × (12/4) × (8/54)
= (3/2) × (3/1) × (4/27)
= (3 × 3 × 4) / (2× 1 × 27)
= 36 / 54
= 6/9
= 2/3
9⁴×12³×8 / 6⁴×4³×54 = 2/3
