How much salt is in a mixture containing 10 gal of an 11% salt solution and 6 gal of a 7% salt solution

1 answer:

4 0

In a 10 gal of an 11% salt solution,

11% of 10 gal are sal.

11% *10 gal=(11/100)*10 gal =0.11*10 gal = 0.1 gal is salt.

Similarly, 0.07*6 gal= 0.42 gal is salt of the 6 gal in the second solution.

The mixture is 10 gal +6 gal = 16 gal, and contains a total of

0.1 gal +0.42 gal = 0.52 gal of salt.

0.52 = x% of 16

0.52=x%*16

x=(0.52/16)*100=0.0325*100=3.25

Answer: there is 0.52 gal of salt in the mixture, that is 3.25%

Write a real world situation that could be modeled by the creation 100 minus 6X equals 160-10 X

nikitadnepr [17]

Answer:

Suppose you have $100 and you spent 6 dollar each day, and your friend has $160 and he/she spent $10 each day. After x days you both have equal amount, find the number of days.

Step-by-step explanation:

Consider the provided information.

We need to write a real world situation that could be modeled by the equation 100-6x=160-10x.

You can use any situation to represents this equation.

The left side of the equation consists of a constant and a variable also the right side of the equation consists of a constant and a variable.

Suppose you have $100 and you spent 6 dollar each day, and your friend has $160 and he/she spent $10 each day. After x days you both have equal amount, find the number of days.

Help please help i need the answer

ASHA 777 [7]

2x+3y=6

- subtract 2x from both sides

3y = -2x + 6

- divide each term by 3

$\frac{3y}{3} = -\frac{2x}{3} + \frac{6}{3}$

- simplify

$\frac{6}{3} = 2$

$y= -\frac{2x}{3} + 2$

- write in slope-intercept form

$y= -\frac{2}3} x+6$

1. We are given:
$a^2 = 64$

The only a which squared gives you 64 is 8. The perimeter of an 8 by 8 square will be 32. Half of that is 16. Now, let's see what we can do. We can set up:
$4a = 16$

Obviously, each side length has to be 4. So, the area of this square will be 16 units².

2. Let n equal her son's age. So, her age right now will be (S = her age):
$S = 18n$
1 year ago it was:
$S-1 = 3n$

We have 2 equations, let's substitute. We can rewrite this as:
$18n-1 = 3n$
Solve for n:
$15n-1=0$
$n= \frac{1}{15}$

We know the value of n, which is her son's age. So, her son is 1/15 of a year old or about 24 days old.
