A salesperson works 40 hours per week at a job where sheshe has two options for being paid. Option A is an hourly wage of ​$23.
Alla [95]
23x40= 920

55% of 920=506
So we know she needs to make over double of 506 to make 920$ commission, so

1675x0.55=921.25 $ in commission. So she would have to sell 1675$ to make roughly the same

I hope that’s right.

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

Suppose tht four times the square of a numbr equals 20 times that number wht is the number​
GuDViN [60]

HOPE THIS HELP')

The number is 5.

Step-by-step explanation:

Finding the Number

To find the number, we have to form the algebraic equation first by translating the given mathematical problem above to algebraic expression. The algebraic equation is a statement that shows the equality of two algebraic expressions.

Equation:

Let "x" be the number.

"four times the square of a number" = 4x²

"20 times that number" = 20x

"four times the square of a number equals 20 times that number"

4x² = 20x

Solution:

4x² = 20x

4x²/4x = 20x/4x

x = 5

Final Answer:

The number is 5.

Checking:

To check, substitute the number.

4x² = 20x

4(5²) = 20(5)

4(25) = 100

100 = 100 ✔
