How much salt is in a mixture containing 10 gallons of an 11% salt solution and 6 gallons of a 7% salt solution?
I think I can solve it but forming the equation is where I have problems.

Answers

Answer:

Step-by-step explanation:

There really isn't an equation because there isn't an unknown. If we create a table, the "equation" that you are talking about will be come apparent. Let's call the 2 solutions Sol 1 and Sol 2:

Gallons of solution * % salt = Gallons of salt

Sol 1

Sol 2

If we fill in this table according to the info we are given, we have 10 gallons of the 11% solution, and 6 gallons of the 7% solution, so

Gallons of solution * % salt = Gallons of salt

Sol 1 10 .11 = 1.1 gallons of salt

Sol 2 6 .07 = .42 gallons of salt

We multiply the Gallons of solution by the % salt to get the gallons of salt. There are 1.1 gallons of salt in solution 1 and .42 gallons of salt in solution 2, so in the mixture (which is 16 gallons) there is 1.1 + .42 gallons of salt, which is 1.52 gallons of salt.

What’s the answer 40=16-8r ?

Answers

Answer:

-3

Step-by-step explanation:

40=16-8r

Subtract 16 from both sides.

24=-8r

Now divide by -8

-3=r

Answer:

-3= r

Step-by-step explanation:

40= 16- 8r

subtract 16 from both sides

40-16= 16 - 16 -8r

24= -8r

divide both sides by -8

24/-8 = -8r/-8

-3= r

Sonya buys four pairs of shoes on sale for buy one, get one 50% off. The sales tax is 6.5%. If the original price for each pair of shoes was $35, how much does Sonya pay for the four pairs altogether?

Answers

$105 * 6.5 % = 6. 825

$105 + 6.825= 111.825

round up since you cant have 825 cents

$111.83

Hi can someone tell me how is the answer 113?? how do i type it in the calculator?? im confused can someone please explain ASAP!!!!!!!!

THANK YOU

Answers

You shouldn't need a calculator for this. The quadratic equation is written in standard form.

ax^2 + bx + c = 0

You substitute a, b, and c into the discriminant formula and solve as shown in the example in the picture you provided.

(-7)^2 - 4(2)(-8)

49 - 4(-16)

49 - (-64)

49 + 64

12 more than quotient of a number k and 5

Answers

Answer:

(k/5)+12 represents the question described

The required equation is 12 + k/5.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now the given statement is,

12 more than quotient of a number k and 5

Converting them into numerical form,

quotient of a number k and 5 = k/5

Therefore 12 more than quotient of a number k and 5 is written as,

12 + k/5

this is the required equation for the given statement.

Thus, the required equation is 12 + k/5.

Answer:

[tex]x_1=-\frac{3}{2} \\\\x_2=-1[/tex]

Step-by-step explanation:

the general fromula is

[tex](ax+b)(cx+)d)\\\\=acx^{2} +(ad+bc)x+bd[/tex]

so we need that

[tex]ac=2\\\\ad+bc=5\\\\bd=3[/tex]

for ac = 2

we only have 2 and 1

so let's say

[tex]a=2\\\\c=1[/tex]

so we now have

[tex](2x+b)(x+d)\\\\2x^{2} +(2d+b)x+bd\\\\[/tex]

and for bd = 3

we only have 3 and 1

but we need to

2d +b = 5

so we can have

b=3

and

d=1

so the factorized form is

[tex](2x+3)(x+1)[/tex]

so we come back to

[tex](2x+3)(x+1)=0[/tex]

so here we have two cases

Case 1

[tex](2x+3)=0\\\\2x+3=0\\\\2x=-3\\\\x=-\frac{3}{2}[/tex]

Case 2

[tex](x+1)=0\\\\x+1=0\\\\x=-1[/tex]

so those are our solutions

CHAPTER II-THE SHE-WOLF, an excerpt From White Fang By Jack London Breakfast eaten and the slim camp-outfit lashed to the sled, the men turned their backs on the cheery fire and launched out into the darkness. At once began to rise the cries that were fiercely sad-cries that called through the darkness and cold to one another and answered back. Conversation ceased. Daylight came at nine o'clock. At midday the sky to the south warmed to rose-colour, and marked where the bulge of the earth intervened between the meridian sun and the northern world. But the rose-colour swiftly faded. The grey light of day that remained lasted until three o'clock, when it, too, faded, and the pall of the Arctic night descended upon the lone and silent land. As darkness came on, the hunting-cries to right and left and rear drew closer-so close that more than once they sent surges of fear through the toiling dogs, throwing them into short-lived panics. At the conclusion of one such panic, when he and Henry had got the dogs back in the traces, Bill said: "I wisht they'd strike game somewheres, an' go away an' leave us alone." "They do get on the nerves horrible," Henry sympathized. They spoke no more until camp was made.
