andreyandreev [35.5K]

Answer:

2 to the sixth, 4 to the third, 8 squared

Step-by-step explanation: 2*2*2*2*2*2=64 because you would have 2, 4,8,16,32,64

4*4*4=64 because you would have 4,16,64

8*8=64

A prescription calls for the following: Sodium citrate 5 g Tartar Emetic 0.015 g Cherry syrup ad 120 mL Using a balance with a s

ella [17]

Answer:

measure the volume of cherry syrup solution with Tartar Emetic = 22.5 mL

Hence, the correct quantity of tartar emetic to fill the prescription will be obtained

Step-by-step explanation:

Given:

Mass of Sodium citrate = 5 g

Mass of Tartar Emetic = 0.015 g = 15 mg

Volume of Cherry syrup ad 120 mL = 120 mL

sensitivity = 4 mg

Error = 5%

Now,

The smallest weight that can be measured = $\frac{\textup{Sensitivity}}{\textup{Error}}\times100$

or

The smallest weight that can be measured = $\frac{\textup{4}}{\textup{5}}\times100$ = 80 mg

Now,

80 mg is dissolved in 120 mL of Cherry syrup according to prescription

( Thus,

1 mg is dissolved in $\frac{120}{80}\ mL$ of Cherry syrup according to prescription )

so to measure 15 mg of Tartar Emetic, measure the volume of cherry syrup

= $15\times\frac{120}{80}\ mL$

= 22.5 mL

Hence, the correct quantity of tartar emetic to fill the prescription will be obtained

Homework: 5.1 Systems of Linear Equations

Klio2033 [76]

Answer:

$\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}$

$x=8,\:y=5$

Step-by-step explanation:

Given the system of linear equations

$7x-y=51$

$x+3y=23$

solving by the elimination method

$\begin{bmatrix}7x-y=51\\ x+3y=23\end{bmatrix}$

$\mathrm{Multiply\:}x+3y=23\mathrm{\:by\:}7\:\mathrm{:}\:\quad \:7x+21y=161$

$\begin{bmatrix}7x-y=51\\ 7x+21y=161\end{bmatrix}$

$7x+21y=161$

$-$

$\underline{7x-y=51}$

$22y=110$

so

$\begin{bmatrix}7x-y=51\\ 22y=110\end{bmatrix}$

now solving for y

$22y=110$

$\mathrm{Divide\:both\:sides\:by\:}22$

$\frac{22y}{22}=\frac{110}{22}$

$y=5$

$\mathrm{For\:}7x-y=51\mathrm{\:plug\:in\:}y=5$

$7x-y=51$

$7x-5=5$

$7x=56$

$\mathrm{Divide\:both\:sides\:by\:}7$

$\frac{7x}{7}=\frac{56}{7}$

$x=8$

$\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}$

$x=8,\:y=5$
