In a lab a 30% acid solution is being mixed with a 5% acid solution to create a 10% acid solution. What is the ratio
of the amount of the 30% solution to the amount of 5% solution used to create the 10% solution?
1.3
1:4
1.5
1.6
Done
Intro

Answers

Answer:

1:4

Step-by-step explanation:

If x is the volume of 30% acid solution, and y is the volume of 5% acid solution, then:

0.30x + 0.05y = 0.10(x + y)

0.30x + 0.05y = 0.10x + 0.10y

0.20x = 0.05y

x/y = 0.05/0.20

x/y = 1/4

Solve the following system of equations using substitution or elimination. 4x-2y+3z=1
x+3y-4z=-7
3x+y+2z=5
PLEASE HELP !!!

Answers

[1] 4x - 2y + 3z = 1

[2] x + 3y - 4z = -7

[3] 3x + y + 2z = 5

Add -4 [2] to [1], and add -3 [2] to [3] to eliminate x :

-4 (x + 3y - 4z) + (4x - 2y + 3z) = -4 (-7) + 1

-4x - 12y + 16z + 4x - 2y + 3z = 28 + 1

[4] -14y + 19z = 29

-3(x + 3y - 4z) + (3x + y + 2z) = -3 (-7) + 5

-3x - 9y + 12z + 3x + y + 2z = 21 + 5

-8y + 14z = 26

[5] -4y + 7z = 13

Add 2 [4] to -7 [5] to eliminate y :

2 (-14y + 19z) - 7 (-4y + 7z) = 2 (29) - 7 (13)

-28y + 38z + 28y - 49z = 58 - 91

-11z = -33

z = 3

Plug this into either [4] or [5] to solve for y :

-4y + 7 (3) = 13

-4y + 21 = 13

-4y = -8

y = 2

Plug both of these solutions into either of [1], [2], or [3] to solve for x :

x + 3 (2) - 4 (3) = -7

x + 6 - 12 = -7

x = -1

The number of apples left to eat are equivalent to 4.

What is percentage?

In mathematics →

a percentage is a number or ratio expressed as a fraction of 100.it is often denoted using the percent sign "%".

Given is that you have 5 apples to eat during the week and you eat 20% on the first day.

Assume the number of apples left are {x}. So, we can write -

{x] = 5 - 20% of 5

{x} = 5 - (20/100) x 5

{x} = 5 - 1

{x} = 4

Therefore,

The price of a necklace was increased by 10% to £121.
What was the price before the increase?

Answers

Answer:

108.90

Step-by-step explanation:

To find its price before the increase you say:

10% of 121 then the answer you subtract it from 121:

10 / 100 * 121 = 12.10

Then subtract 12.10 from 121

121-12.10= 108.90

So the price before the increase was 108.90

GEOMETRY Write and solve an equation to find the value of x so that it figures have the same area.

Answers

Answer:

C. x=7 and the expression is (5+x)9=x*(15 3/7)

Step-by-step explanation:

The width of the first shape is 5+x and the length is 9

The width of the second shape is x and the length is 15 3/7

You want the same area of the figures, so they are equal. And the formula for the area of a rectangle is l*w. So...

(5+x)9=x*(15 3/7)

45+9x=(108/7)x

315+63x=108x

63x-108x=-315

-45x=-315

x=7

So, your answer is C.

Between the years 1800 and 1860, arguments between the North and South grew more intense. One of the main quarrels was about taxes paid on goods brought into this country from foreign countries. This tax was called a tariff. Southerners felt these tariffs were unfair and aimed toward them because they imported a wider variety of goods than most Northern people. Taxes were also placed on many Southern goods that were shipped to foreign countries, an expense that was not always applied to Northern goods of equal value. An awkward economic structure allowed states and private transportation companies to do this, which also affected Southern banks that found themselves paying higher interest rates on loans made with banks in the North. The situation grew worse after several panics, including one in 1857 that affected more Northern banks than Southern. Southern financiers found themselves burdened with high payments just to save Northern banks that had suffered financial losses through poor investment.This text is an example of a(n)_____________.1.literary nonfiction text, because it tells a story2.memoir, because it's a personal account of an event3.expository text, because it explains information4.persuasive text, because it persuades the reader5.historical fiction text, because the setting is historical, but the story is fictional Question:A recipe says to use 3.5 cups of flour to make 48 cookies.
