We have 500 grams of a 10% salt solution. How many grams of water must be added to dulite the solution to form a 4% solution. Sh

lys-0071 [83]

Hmm, one way is this
there's 500 times 0.10 or 50 grams of salt in the water
if we want to make 50 grams=4% of everything, how much water do we need to add

50=4% of all
50=0.04 of all
divide both sides by 0.04
1250=all
so
500+what=1250
minus 500 both sides
what=750

750 grams of water

Circle A has a radius of 9 centimeters and Circle B has a diameter of 19 centimeters. What is the relationship between the circu

IRISSAK [1]

Answer:

18:19

Step-by-step explanation:

Given that,

The radius of circle A = 9 cm

The diameter of circle B = 19 cm

We know that,

Radius = diameter/2

The radius of circle B = 19/2 cm

The circumference of circle A is :

$C_A=2\pi r_A$ ....(1)

And that of circle B is :

$C_B=2\pi r_B$ ....(2)

Dividing equation (1) and (2) :

$\dfrac{C_A}{C_B}=\dfrac{2\pi r_A}{2\pi r_B}\\\\=\dfrac{r_A}{r_B}\\\\=\dfrac{9}{\dfrac{19}{2}}\\\\\dfrac{C_A}{C_B}=\dfrac{18}{19}$

Hence, the ratio of circumferences of Circle A and Circle B is 18:19.

Is -1 and 4/5 greater than -2 and 1/8

Goryan [66]

Hey there!

The correct answer is yes.

The smaller the number with a negative sign, the larger the number actually is.
So, -1 4/5 > -2 1/8

Hope this helps! :)
