Answer:
3/2 = 6/4
Step-by-step explanation:
Given that ∆BDE ~ ∆BAC by dilation of a scale factor of 2, it means therefore that:
BA/BD = BC/BE = AC/DE = 2
BD = 2
BA = 2*BD = 2*2 = 4
BE = 3
BC = 2*BE = 2*3 = 6
DE = 3.61
AC = 2*DE = 2*3.61 = 7.22
Also:
<D = <A,
<E = <C
=>Find tan <D, and tan <A using trigonometric function to determine which proportion gives us tan<D = tan<A
Tan<D = opposite/adjacent
Tan<D = BE/BD
Tan<D = 3/2
Tan<A = opposite/adjacent
Tan<A = BC/BA
Tan<A = 6/4 = 3/2
<em>Therefore, the proportion that proves that tan<D = tan<A is:</em>
<em>BE/BD = BC/BA = 3/2 = 6/4</em>
Answer:
I won't be able to solve the entire question but I will give you the formula and show you how to find the answer
4) 1.65x + 1.36y = 118.17 (i)
x + y = 79. (ii)
From the (i) equation you get
1.65x = 118.17 - 1.36y
x = (118.17 - 1.36y)/1.65 (iii)
Substituting the value of (iii) in (ii)
(118.17-1.36y)/1.65 + y = 79
When you solve it you will get the answer
After that find the value of x and y and multiply them by 1.65 and 1.36 respectively.
Then find their difference and see which class sold more and by how much.
Hope this helps you!

Step-by-step explanation:
4 x 6 1/4
4 x 25/4
= 25
Answer:
26 is the number
Step-by-step explanation:
12/13 x = 24
Multiply by 13 on both sides
12x = 24 * 13
12x = 312
Simplify
x = 26
26
Hope this helps :)
Answer:
Scales are used to represent real distances and proportions into maps and planes, that way we can have a bigger perspective about something just having in paper.
One direct use of scales are seen in architecture plans, there, the architect uses scales to represent the construction he is designing. Also, the architect can have a more complete point of view about the principial elements on his work.
