Answer:

First option

The lines are perpendicular to each other because -8 and 1/8 are opposite reciprocals of each other

Step-by-step explanation:

y = -8x - 5/4; slope = -8

y = 1/8 x + 4/5; slope = 1/8

Perpendicular lines, slope is opposite and reciprocal.

So both lines are perpendicular to each other because -8 and 1/8 are opposite reciprocals of each other

When it is born a kitten weighs 110g when it is two months old it weighs 550g calculate the percentage increase in its mass

torisob [31]

Given:

Initial weight of kitten = 110g

Present weight of kitten = 550g

To find:

The percentage increase in its mass.

Solution:

To get the percentage increase in its mass, we need to find the percentage increase in its weight.

$\%Increase=\dfrac{\text{Present value - Initial value}}{\text{Initial value}}\times 100$

$\%Increase=\dfrac{550-110}{110}\times 100$

$\%Increase=\dfrac{440}{110}\times 100$

$\%Increase=4\times 100$

$\%Increase=400$

Therefore, the percentage increase in kitten's mass is 400%.

A square based pyramid is 70.56N the pyramid exerts a pressure of 4900N/m2 on the table.

nignag [31]

Answer:

${ \tt{pressure = \frac{force}{volume} }} \\ \\ { \tt{4900 = \frac{70.56}{v} }} \\ \\ { \tt{v = \frac{70.56}{4900} }} \\ \\ { \tt{ \underline{ \: v = 0.0144 \: {m}^{3} \: }}}$
