Answer:

v=9

Step-by-step explanation:

There's a property in geometry called the vertical angles postulate, which means that angles on opposite sides of two intersecting lines are congruent, meaning they have the same measure. So, we already know that one value of the angle is 50 degrees, and 6v-4 is also 50 degrees, because of the vertical angles postulate. We can then solve with basic algebra. 6v-4=50, so 6v=50+4. 6v=54, so v=54/6. 54 divided by 6 is 9, therefore v is equal to 9.

The value of a motorbike depreciates by 32% per year. Work out the current value of a motorbike bought 5 years ago for £3600

DaniilM [7]

$\bf \qquad \textit{Amount for Exponential Decay}
\\\\
A=P(1 - r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &3600\\
r=rate\to 32\%\to \frac{32}{100}\to &0.32\\
t=\textit{elapsed time}\to &5\\
\end{cases}
\\\\\\
A=3600(1-0.32)^5\implies A=3600(0.68)^5\implies A\approx 523.41601$

Can you say how 2345 and 111 happened

g100num [7]

Answer:

1 3 6 10 15 is added by 2345

and 2345 is added by 111

Step-by-step explanation:

1+2= 3 3+3=6 6+4=10 10+5=15 so it's added by 2345

2+1=3 3+1=4 4+1=5 so that's why it's added by 1

A circular pond has a diameter of 17 feet. There is pathway around the rim of the pond. What is the length of the pathway?

NeX [460]

Answer:

53.38ft

Step-by-step explanation:

By it asking the length of the pathway, in math terms its just asking you the circumfrence of the pond.

C = 2( $\pi$ )(r)

C = 2(3.14)(17/2)

C = 2(3.14)(8.5)

C = 53.38ft
