Answer:
14yd
Step-by-step explanation:
Scale of the model:
1in to 2yd
This suggest that for every 1in on the model, the actual distance is 2yd.
So;
A model 7in wide will actually be:
1in to 2yd
7in will be 7 x 2 = 14yd
When all three sides are equal it’s an equilateral triangle
I'm going to write out the work and take a pic. hope this helps you understand if not, feel free to ask me Q's! :)
Number 1 is A.
Number 6 is C.
Simplification of (-2/5) divided by (8/9) times (2/9) divided by (-1/3) is 0.3
<em><u>Solution:</u></em>
Given that,
Simplify (-2/5) divided by (8/9) times (2/9) divided by (-1/3)
Here "times" represent multiplication
<em><u>The above sentence can be written mathematically as:</u></em>

Convert the problem to multiplication by changing the division sign to multiplication. When we change division sign to multiplication, the fraction becomes reciprocal

Cancelling the common terms in numerator and denominator,

Multiplying terms in numerator and denominator,

Negative sign in numerator and denominator cancels each other

Reducing to lowest terms we get,

In decimal form we get,

Thus solution to given expression is 0.3
