LekaFEV [45]
100%/x%=80/20 (100/x)*x=(80/20)*x - we multiply both sides of the equation by x 100=4*x - we divide both sides of the equation by (4) to get x 100/4=x 25=x x=25

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 radius of a circle is 6mm. What is the area of the shaded portion of the circle.
mariarad [96]

Answer:

b) 29π mm²

Step-by-step explanation:

\frac{360}{360}  - \frac{70}{360}  =  \frac{290}{360}  \\  \\\pi \:  {r}^{2} \\  =    \frac{290}{360}  \times \pi\times 6 \times 6 \\  =  29 \: \pi  \: {mm}^{2}
