Apples lose 85% of their weight while drying. What weight of fresh apples do you need to pick in order to get 10.5 lb of dried apples?

Answers

Answer 1

Answer:

Answer:

$70\ lb$

Step-by-step explanation:

Let

x------> weight of fresh apples

we know that

$85\%=(85)/(100)=0.85$

$(1-0.85)x=10.5$

$0.15x=10.5$

Solve for x

Divide by $0.15$ both sides

$x=10.5/0.15$

$x=70\ lb$

Answer 2

Find the gradient of the line segment between the points (-2,3) and (-4,-2).Give your answer in its simplest form.

Answers

Given:

The two points are (-2,3) and (-4,-2).

To find:

The gradient of the line segment between the given points.

Solution:

The gradient is also known as slope.

The slope formula:

$m=(y_2-y_1)/(x_2-x_1)$

The endpoints of the line segment are (-2,3) and (-4,-2). So, the gradient of the line is

$m=(-2-3)/(-4-(-2))$

$m=(-5)/(-4+2)$

$m=(-5)/(-2)$

$m=(5)/(2)$

Therefore, the gradient of the given line segment is $m=(5)/(2)$ .

Tai resized a photograph that was 8 inches by 10 inches so that it would fit on a 4 inch by 4 inch page. Find the maximum dimensions of the reduced photograph. An explanation wold be great, please. Thank you so much!

Answers

ok so it has to be max 4 inches when resized since the max size is 4 inches

10 is max of original so
they have to be shrunk in same ratio so find ratio of shrink
10 times ratio=4
divide both sides by 10
ratio=4/10=2/5
so multiply the measuremet by 2/5 to find new dimention

8 times 2/5=16/5=3 and 1/5=3.2

new dimentions is 4 by 3.2 inches
