Answer:

1188 grams

Step-by-step explanation:

You want the 12g of sugar to be 1% of the whole solution.

So, say you add  grams of water. The solution will be composed of 12 grams of sugar and  grams of water, for a total of  grams.

So, the ratio "sugar/total" will be

and we want this ratio to be 1%, i.e. 1/100:

Multiply both sides by 100 and  to get

Subtract 12 from both sides:

So, a solution composed of 1188 grams of water and 12 grams of sugar will be 99% water and 1% sugar.

Answer: 1188 grams of water

Step-by-step explanation:

Sugar = 1% = 12

Whole = 100% = 12·100 = 1200

Water = 99% = 1200 - 12 = 1188

You Need 1188 Grams Of Water To Make The Solution 1% Sugar

Answer:

[tex]A_{total} = 132\ ft^2[/tex]

Step-by-step explanation:

Step 1:  Determine the area of the rectangle

[tex]A = l * w[/tex]

[tex]A = 9\ ft * 11\ ft[/tex]

[tex]A = 99\ ft^2[/tex]

Step 2:  Determine the area of the triangles

[tex]A = \frac{h * b}{2}[/tex]

[tex]A=\frac{(15\ ft - 9\ ft)*(11\ ft / 2)}{2}[/tex]

[tex]A=\frac{6\ ft * 5.5\ ft}{2}[/tex]

[tex]A = 16.5\ ft^2[/tex]

Since we found only one of the right triangles we need to multiply the area that we got by 2 to get the total triangle area.

[tex]A = 16.5\ ft^2 * 2[/tex]

[tex]A = 33\ ft^2[/tex]

Step 3:  Determine the total area

[tex]A_{total} = 99\ ft^2 + 33\ ft^2[/tex]

[tex]A_{total} = 132\ ft^2[/tex]

Answer:  [tex]A_{total} = 132\ ft^2[/tex]

Answer:

Slope = 3

Step-by-step explanation:

Slope is calculated as the "Rise/Run" of a straight line.  The Rise is the change in the value of y, or the amount y changes per change in x.  Run is the change in the x value.  A line with a run of 3 and a rise of 9 is calculated as:

Rise/Run = 9/3 or 3

This means that the value of y will increase by 3 for every increase of 1 in the value of 3.

Slope in "m" in the slope-intercept form of a straight line equation:  y = mx + b

The line y = 3x + 2 tells us the it has a slope of 3 and intercepts the y axis at x = 2.

Example points (y = 3x + 2)

(0,2)

(1,5)

(4,14)

Note that y changes by 12 when x changes by 4.  Rise/Run = 12/4 or 3.

To find one tenth of a number, simply divide it by 10 . The easiest way to do that is to : cross off a zero at the end if there is one. move the decimal one place to the left.

Answer:

4.5 = x

Step-by-step explanation:

Given:

22.5 = 5x

(we need to find out what x is)

22.5 / 5 = 4.5

meaning that the duck traveled at 4.5 kilometers per hour.

Check:
4.5 x 5 = 22.5

x=y-0.5y

simplify

x=0.5y

times two on both side

2x=y

y=2x

In quadratic equation, x = 1/7, -4 are the values of x will the function f(x) .

What in mathematics is a quadratic equation?

A quadratic equation is a second-order polynomial equation in one variable using the formula x = ax2 + bx + c = 0 and a 0. The fundamental theorem of algebra ensures that it has at least one solution because it is a second-order polynomial problem. 

f(x) = 7x² + 27x - 4

       = 7x² + ( 28 - 1 )x - 4

       = 7x²  + 28x - x - 4

        = 7x( x + 4) -1( x + 4 )

         = (7x - 1 ) ( x + 4)

     7x - 1 = 0

        x = 1/7

   x + 4 = 0

        x = -4

Answer:

√500

Step-by-step explanation:

Answer: 126

Step-by-step explanation:

55% of student population is girls

if there are 154 girls then
0.55x = 154, where x represents school population

x=280

assuming the school only has boys and girls, anyone that's not a girl must be a boy, so

boys = 280 - 154 = 126.

if the school is not only boys and girls,

there will be 126 or less boys

Answer:

$879.76575 --> $880

Step-by-step explanation:

$808.98 × 0.0875 = $70.78575 <-- this represents the additional sales tax

$808.98 + $70.78575 = $879.76575 <-- add sales tax to original price

Answer:

  (d)  2x +y = 8

Step-by-step explanation:

The answer choices are shown in "standard form," so the comparison to the given equation is easier if it is written in standard form. Add 2x to both sides:

  2x +y = 5 . . . . . . given equation in standard form

The other equation in a system with no solution will look like this, but will have a different constant:

  2x +y = 8 . . . . . . does not intersect the given equation

_____

Additional comment

All of the other equations shown will intersect the given equation. One way to show this is to use the given equation to substitute for y in the answer choices:

  a: 2x -(-2x+5) = 8   ⇒   6x -5 = 8 . . . one solution: x=13/6

  b: x +2(-2x+5) = 8   ⇒   -3x +10 = 8 . . . one solution: x=2/3

  c: x -2(-2x+5) = 8   ⇒   5x -10 = 8 . . . one solution: x=18/5

  d: 2x +(-2x+5) = 8   ⇒   5 = 8 . . . no solution

Answer:

50.26 in

Step-by-step explanation:

First you need the circumference of half of a circle.

Circumference = diameter x pi. The radius is 9, so the diameter is 18. 18 * 3.14 = 56.52. But you need half of that, so 56.52 / 2 = 28.26

Then add the other 3 sides

28.26 + 5 + 12 + 5 = 50.26

Answer:

i) 8

ii) yes 400 is a value in the sequence as the nth term would be 200 for that, 400 is also divisible by 2, and as 2 is the coefficient of n, 400 can be a value in the sequence.

Step-by-step explanation:

for n as term number:

n = 4

2n = 8

i) 8 is the fourth term

for n as unknown:

2n = 400

400/2 = n

200 = n

ii) yes 400 is a value in the sequence as the nth term would be 200 for that, 400 is also divisible by 2, and as 2 is the coefficient of n, 400 can be a value in the sequence.
