Answer:

I believe it is 1/9 or 11.1%

Step-by-step explanation:

11/99 /(divided by) 11 = 1/9

1/9 converted to a decimal is 0.1 (it's repeating- I am not sure how to do that on brainly w/ the fancy - over it, so it's 0.111111111...)

so as a percent, it makes it 11.1% (repeating) or 11 \frac{1}{9}% (which is a more exact solution)

now if you need a ratio, it would be 1:9

hope this helps :)

A 40% sugar solution is added to an 85% sugar solution to create 1800 mL of a 60% solution. How much of each solution is used? (
denis-greek [22]

Answer:

Number of ml of 40% sugar = x = 1000mL

Number of ml of 85% sugar used = y = 800mL

Step-by-step explanation:

Let the

Number of ml of 40% sugar = x

Number of ml of 85% sugar used = y

From the above question, our system of equations is given as:

x + y = 1800mL ....... Equation 1

x = 1800 - y

40% × x + 85% × y = 60% × 1800mL

0.4x + 0.85y = 1080.... Equation 2

We substitute 1800 - y for x in Equation 2

0.4(1800 - y) + 0.85y = 1080

720 - 0.4y + 0.85y = 1080

- 0.4y + 0.85y = 1080 - 720

0.45y = 360

y = 360/0.45

y = 800mL

Solving for x

x = 1800 - y

x = 1800 - 800

x = 1000mL

Therefore,

Number of ml of 40% sugar = x = 1000mL

Number of ml of 85% sugar used = y = 800mL

The length of a rectangle is times the width. If the perimeter is 32 inches, what is the width of the rectangle
o-na [289]
Let width be “w", length = “l" and perimeter = p

Then l = 3w-4

Perimeter = 2(w+l)

p = 2(w+3w-4) = 2w+6w-8 = 8w-8

Perimeter is 32…

8w-8 = 32

8w = 32+8

8w = 40

w = 5

l = (3×5)-4 = 11

Check… p = 2(5+11) = 2 × 16 = 32

Ans = length is 11

Hope it helps!
