Please help! If the two triangles are similar, which equation represents the value of side x?
madam [21]

x=\frac{p q}{m} equation represents the value of side x.

Solution:

The two triangles are similar.

<em>If two triangles are similar, then the corresponding sides are in proportional.</em>

$\Rightarrow \frac{m}{p} =\frac{q}{x}

Do cross multiplication.

$\Rightarrow mx=pq

Divide by m on both sides.

$\Rightarrow \frac{mx}{m} =\frac{pq}{m}

$\Rightarrow x =\frac{pq}{m}

Therefore, x=\frac{p q}{m} equation represents the value of side x.

A dress that is size x in France is equaivalent to size​ d(x) in the United​ States, where ​d(x)x32.
kobusy [5.1K]

Answer:

(a)\ d'(x) = x + 32 i.e. The inverse function

(b)\ d'(10) = 42 i.e. The French size of a dress if it is U.S. size 10 is 42.

Step-by-step explanation:

Given

d(x) = x - 32

Solving (a): The inverse function

d(x) = x - 32

Replace d(x) with y

y = x - 32

Swap y and x

x = y - 32

Make y the subject

y = x + 32

Replace y with d'(x)

d'(x) = x + 32

Hence, the inverse function is: d'(x) = x + 32

Solving (b): US size of 10

d'(x) = x + 32

Substitute x  =10

d'(10) = 10 + 32

d'(10) = 42

You are given two variables, already declared and assigned values, one of type double, named totalWeight, containing the weight
Alchen [17]

Answer:

double singleWeight = totalWeight/quantity;

Step-by-step explanation:

Considering you already have two different declared and assigned variables, in C language you would have the following lines:

#include <stdio.h>

int main()

{

   double totalWeight = 5.2 ;

   int quantity = 2;

   double singleWeight = totalWeight/quantity;

   

   // Displays operation      

   printf("%f / %d = %f", totalWeight, quantity, singleWeight);

   return 0;

}

It is very important to keep in mind that the type of variable of singleWeight is double due to the expecting number is the result of the division where the dividend is double too.

each case of apples Jake buys weighs 24 lb which equation tells the number of pounds in any number of cases
klio [65]

Answer:

p = 24c

Step-by-step explanation:

This is called a dependent variable problem. The independent variable (the one that is given) is the number of cases. It is on the right side of the equation.

The dependent variable is the one on the left and it is found when you know the number of cases. The correct equation is

p = 24*c
