Triangle abc is similar to triangle def solve for both unknown sides

Mathematics
1 answer:
Serhud [2]2 years ago
7 0

Given:

Triangles ABC and DEF are similar triangles.

AB = 6 m, BC = 16 m, CA = 15 m, DE = x, EF = 32 m, FD = y

To find:

The values of unknown sides, i.e., x and y.

Solution:

We know that the corresponding parts of similar triangles are proportional and triangles ABC and DEF are similar triangles, so

\dfrac{AB}{DE}=\dfrac{BC}{EF}=\dfrac{CA}{FD}

\dfrac{6}{x}=\dfrac{16}{32}=\dfrac{15}{y}

\dfrac{6}{x}=\dfrac{1}{2}=\dfrac{15}{y}

Now,

\dfrac{6}{x}=\dfrac{1}{2}

6\times 2=1\times x

12=x

Similarly,

\dfrac{1}{2}=\dfrac{15}{y}

1\times y=15\times 2

y=30

Therefore, the measure of unknown sides are x = 12 m and y = 30 m.

Esther is participating in a walk-a-thon. She will raise 5 dollars for her charity for each lap she walks.
avanturin [10]

Answer:

independent variable = number of laps;

dependent variable = number of dollars​

Step-by-step explanation:

If we were to put this information into a slope-intercept form equation, the equation would be: y = 5x (dollars raised = 5 dollars per lap walked). In this case, we are going to use the variables l and d instead of x and y, respectively. The equation instead of being y = 5x, it is going to be d = 5l. In the slope-intercept form X will always be the independent variable and y the dependent variable, because the number we get for Y totally depends on what you plugged in for X. In this equation, l is the independent variable (the number of laps she walks) and d is the dependent variable (number of dollars).

How many miles will a person run during a 10 kilometer race?
faltersainse [42]
There are 1,61 kilometers in a mile or more correctly 1,60934 kilometers in a mile. 
<span>But first, a short history.... Both kilometers and miles are units of measurement. They are used to measure distance. Miles are part of the imperial measurement system and kilometers are part of the metric measurement system. </span>
To calculate how many miles a person will run during a 10-kilometer race, you need to divide 10 kilometers by 1,61 miles (1,60934 rounded up to two digits).

Therefore your equation is as follows:

10÷1,61 or 10 000 meters ÷ 1 610 metres 
1000 meters is equal to 1 kilometer. 

The answer = 6, 21 miles. 

Therefore, a person who runs 10 kilometers will run 6,21 miles
