Answer:

$191.70

Step-by-step explanation:

total amount spent = cost of medicine + cost of tax + cost of shipping

cost of tax = 0.05 x $180 = $9

cost of shipping 0.015 x $180 = $2.70

total cost = $180 + $9 + 2.70 = $191.70

A group of chemists are conducting an experiment to produce a new liquid material. One chemical contains 15% sodium (Na) and the

lesantik [10]

Answer:

A= 320 and B = 280

Step-by-step explanation:

Amount of sodium from first material = 0.15*A
Amount of sodium from second material = 0.3*B

Now, if we combine the two chemicals to get a new chemical, which is 22% sodium, then the total amount of combined sodium is amount of sodium from both sources

<=> 0.15A + 0.3B = 0.22*(A+B)

<=> 0.07A - 0.08B = 0 (1)

- But we have a second equation, because we know that A + B = 600 (2)

Solve the system of two equations, (1) and (2), we have:

A= 320 and B = 280

Solve for x and then type the answer. Just type the number. If there are 2 answers, then type both numbers, separated by a comma

Basile [38]

(x + 2)^(1/3) = 3 equivalent to ∛[(x+2)] = 3

Raise both sides to exponent 3

x+2 = 3³===> x+2 = 27 & x=25

Find the distance between the two points rounding to the nearest tenth (if necessary).

Genrish500 [490]

Answer:

13 units

Step-by-step explanation:

(-1,5) and (4, -7)

To find the distance of two points, we use the distance formula:

$d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }$

Let's plug in what we know.

$d = \sqrt{(4 - (-1))^2 + (-7 - 5)^2 }$

Evaluate the double negative.

$d = \sqrt{(4 +1))^2 + (-7 - 5)^2 }$

Evaluate the parentheses.

$d = \sqrt{(5)^2 + (-12)^2 }$

Evaluate the exponents.

$d = \sqrt{(25) + (144) }$

Add.

$d = \sqrt{(169) }$

Evaluate the square root.

$d = 13$

13 units

Hope this helps!
