Answer: 44.85 units

Step-by-step explanation: In this problem, we are asked to find the perimeter of the trapezoid. Remember that perimeter is the distance around a figure. We can find the perimeter of the trapezoid by adding the lengths of each of the sides.

9.85 + 15 + 11 + 9 = 44.85 units

A student has a 2% salt water solution and a 7% salt water solution. To best imitate salt water at a local beach, he needs 1 lit
FromTheMoon [43]

Let

x-------> the amount of 2\% solution

y--------> the amount of 7\% solution

we know that

2\%=0.02\\7\%=0.07\\3.5\%=0.035

so

x+y=1

y=1-x -------> equation A

0.02x+0.07y=0.035 -------> equation B

substitute equation A in equation B

0.02x+0.07(1-x)=0.035

0.02x+0.07-0.07x=0.035

0.05x=0.035

x=0.7\ liters

find the value of y

y=1-x

y=1-0.7=0.3\ liters

therefore

The student need 0.7\ liters of 2\% solution and 0.3\ liters of 7\% solution

<u>the answer is</u>

A) The percent values were written incorrectly in the equation

B) The amount of 7% solution should be written as 1 – x, not x – 1.

Solve the system of equations by graphing: 2x + 3y = 2 6x + 18y = 9
cluponka [151]
The answer is  A: x=1/2 , y= 1/3

Solve the following system:
{2 x + 3 y = 2 | (equation 1)
{6 x + 18 y = 9 | (equation 2)

Swap equation 1 with equation 2:
{6 x + 18 y = 9 | (equation 1)
{2 x + 3 y = 2 | (equation 2)

Subtract 1/3 × (equation 1) from equation 2:
{6 x + 18 y = 9 | (equation 1)
{0 x - 3 y = -1 | (equation 2)

Divide equation 1 by 3:
{2 x + 6 y = 3 | (equation 1)
{0 x - 3 y = -1 | (equation 2)

Multiply equation 2 by -1:
{2 x + 6 y = 3 | (equation 1)
{0 x+3 y = 1 | (equation 2)

Divide equation 2 by 3:
{2 x + 6 y = 3 | (equation 1)
{0 x+y = 1/3 | (equation 2)

Subtract 6 × (equation 2) from equation 1:
{2 x+0 y = 1 | (equation 1)
v0 x+y = 1/3 | (equation 2)

Divide equation 1 by 2:
{x+0 y = 1/2 | (equation 1)
v0 x+y = 1/3 | (equation 2)

Collect results:
Answer:  {x = 1/2, y = 1/3
