Answer: 50%

Step-by-step explanation:

I'm converting 7kg to grams to make it easier. So £10 = 7000g

£1 = 7000÷10 = 700g

700g÷2 = 350g and if you follow the ratios on top, she payed 50p per 350g

She sells a bag of 350g for 75p.

Percentage profit= $\frac{Change in cost}{original cost}$ × 100

75p - 50p = 25p = change in cost

Percentage profit= $\frac{25}{50}$ × 100

= 50%

Answer:

Step-by-step explanation:

in order to understand which triangle would lie on the given line we should figure out the slope of the given line first

remember that,

$\displaystyle m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}}$

from the graph let's take two points where the line passes i.e (0,0) and (4,6)

substitute:

$\displaystyle m = \frac{6- 0}{ 4 - 0}$

simplify substraction:

$\displaystyle m = \frac{6 }{ 4 }$

reduce fraction:

$\displaystyle m = \frac{3}{ 2}$

now we need a triangle which tan ratio equal to the slope in that case we can consider the third triangle

$\displaystyle \tan( \theta) = \frac{30}{20}$

reduce fraction:

$\displaystyle \tan( \theta) = \frac{3}{2}$

since the tan ratio of the third triangle equal to the slope of the line

hence, our answer is c

Masja [62]

Answer:

x = 8

Step-by-step explanation:

log₅ (10x − 1) = log₅ (9x + 7)

10x − 1 = 9x + 7

x = 8

What is the slope of the line shown below?

Sergio039 [100]

Answer:

Option D

Step-by-step explanation:

We are given the two points of (5, 11) and (-5, -1).

Use the slope formula.

$m=\frac{rise}{run}=\frac{-1-11}{-5-5} =\frac{-12}{-10} =\boxed{\frac{6}{5}}$

The correct option should be Option D.

Hope this helps you.
