Find the probability that she develops lung cancer, given
she smokes.

Answers

To find the probability that she develops lung cancer given that she smokes, multiply the two probabilities together:

4/9 x 3/10 = (4 * 3) / (9*10) = 12/90 = 2/15

Answers

for number 1, you divide both sides by -3 and because it is a negative number, you need to flip the sign so the answer is d.
For number 2, because you need to make the x by itself, you multiply both sides by 5 which gives you c.
For number 3, you add both sides by 4 so you get a.
For number 4, you find the number between -5 and 0 so the answer is c.
For number 5, the answer is b. nothing much to explain.
For number 6, its the greater than with the line underneath
For number 7, the answer is d.
For number 8, b
For number 9, c
For number 10, A

Jamal is making two paintings using canvases that are similar rectangles. The length of the smaller canvas is 3 ft and the width is 5 ft.What is the length of the larger canvas if the width is 10 ft?

Answers

Let's start with what we know:

Smaller canvas:
Length ( $L_(1)$ ) = 3ft
Width ( $W_(1)$ ) = 5ft

Larger canvas:
Length ( $L_(2)$ ) = ?
Width ( $W_(2)$ ) = 10ft

Since these are similar rectangles, we can cross-multiply to calculate the missing length. Here's that formula:

$( L_(1) )/( L_(2) ) = ( W_(1) )/( W_(2) )$
So let's plug it all in from above:

$( 3 )/( L_(2) ) = ( 5 )/( 10 )$
Now we cross multiply by multiplying the top-left by the bottom-right and vice versa:

$(3)(10) = (5)(L_(2))$
$30 = 5L_(2)$
Now divide each side by 5 to isolate $L_(2)$

$(30)/(5) = ( 5L_(2))/(5)$
The 5s on the right cancel out, leaving us with:

$6 = L_(2)$

So the length of the larger canvas is 6 ft

It's not as complicated as you think. The smaller rectangle is 3ft with a width of 5ft. It's asking what the length of the larger canvas is if the width is 10ft. So you pretty much just do 10/5 which is 2 then you multiply 3ft by 2 and you get 6ft.

If you need any help just ask :)

You mix 2/5 cup of red paint for every 1/4 cup of blue paint to make 1 5/8 gallons of purple paint. How much red paint and blue paint do you use

Answers

Answer=16 cups of red and 10 cups of blue

2/5=8/20=32/80
1/4=5/20=20/80
1 5/8gallons=26cups

32/80+20/80=52/80

26=x(52/80)
divide both sides by (52/80)
40=x
In short, you multiply the mixture by 40 , so...

40*2/5=16cups of red
40*1/4=10cups of blue
