In ABC, the measure of sides c is 3.9 cm If DEF is a dilation ABC with a scale factor of 2.5 what is the measure of side f

White raven [17]

Answer:

$F = 9.75cm$

Step-by-step explanation:

Given

In ABC;

$C = 3.9cm$

$Dilation = 2.5$

Required

Determine side F

In the given question;

DEF is a dilation of ABC

Comparing both triangles side by side,

Side F is a direct dilation of side C and this is calculated as follows

$F = Dilation * C$

$F = 2.5 * 3.9cm$

$F = 9.75cm$

The system of equations kx-5y = 2, 6x+2y = 7 has no solution, then k =

hoa [83]

Answer:

(d) -15

Step-by-step explanation:

Given system of equations are:

$\begin{cases}kx-5y=2\\\\6x+2y=7\end{cases}$

Since, given system of equations have no solution.

$\therefore \frac{k}{6}=\frac{-5}{2} \neq\frac{2}{7}$

$\implies \frac{k}{6}=\frac{-5}{2}$

$\implies k=\frac{6(-5)}{2}$

$\implies k=\frac{-30}{2}$

$\implies k=-15$

M=p/n+4 make n the subject

Kipish [7]

Answer:

$n = \frac {p - 4m}{m}$

Step-by-step explanation:

Given the algebraic expression;

$m = \frac {p}{n + 4}$

To make n the subject of formula.

Cross-multiplying, we have;

$m*(n+4) = p$

$mn + 4m = p$

Rearranging the equation, we have;

$mn = p - 4m$

$n = \frac {p - 4m}{m}$
