A solution consisting of 95 mg of dopamine in 95 mL of solution is administered at a rate of 30 ml/hr. Complete parts (a) and (b) below.
a. What is the flow rate in mg of dopamine per hour?
mg/hr (Type an integer or decimal rounded to the nearest thousandth as needed.)
Answer:
30 mg
Step-by-step explanation:
Flow rate of dopamine per hour:
Flow rate of dopamine per hour = (95g)*(30ml/hr) / 95ml
Flow rate of dopamine per hour = 30mg

A rectangle has an area of 18 square feet. A similar rectangle 1
has an area of 160 square feet. What is the ratio of the areas of these
similar rectangles?
Answer:
[tex]Ratio = 9 :80[/tex]
Step-by-step explanation:
Given
[tex]A_1 = 18ft^2[/tex] --- Area of smaller rectangle
[tex]A_2 = 160ft^2[/tex] --- Area of bigger rectangle
Required
Determine the area of the areas.
The ratio is calculated by the dividing the areas of rectangles.
[tex]Ratio = \frac{A_1}{A_2}[/tex]
Substitute values for A2 and A1
[tex]Ratio = \frac{18ft^2}{160ft^2}[/tex]
[tex]Ratio = \frac{18}{160}[/tex]
Simplify the fraction
[tex]Ratio = \frac{9}{80}[/tex]
Represent as ratio
[tex]Ratio = 9 :80[/tex]
Hence, the ratio of the rectangles is 1 to 9

Answer:
Assuming the 19 stood for an exponent, q = 1.098...
Step-by-step explanation:
Plugging in [tex]q^{19} = q + 4[/tex] in the graphical calculator, we can see that the solution is approximately q=1.098. There are no ways of solving this equation algebraically.
Answer:
q = 15
Step-by-step explanation:
19 = q + 4
Subtract 4 from each side
19-4 = q + 4-4
15 = q

HELP ME PLEASE (50 points) picture below HELP PLEASE
Answer:
72.32
Step-by-step explanation:
i have spoken
Answer:
72.32 degrees
Step-by-step explanation:
the picture shows a supplementary angle, which equals 180 degrees.
first, solve for x.
since the entire figure equals 180 degrees, set the equation equal to 180. then add in the measurements, which are 7x, 8x, and 44.4.
180 = 7x + 8x + 44.4
combine like terms (7x and 8x).
180 = 7x + 8x + 44.4 ⇒ 180 = 15x + 44.4
subtract 44.4 from both sides. the positive 44.4 will cancel out, so all you have to do is subtract 44.4 from 180.
180 - 44.4 = 135.6
now, your equation is...
135.6 = 15x
divide both sides by 15.
(135.6)/15 = (15x)/15 ⇒ 9.04 = x, or x = 9.04
now plug 9.04 in for x in both 7x and 8x.
7x ⇒ 7(9.04) ⇒ 63.28
8x ⇒ 8(9.04) ⇒ 72.32
*the highlighted angle, 8x, is 72.32 degrees.
checking your work:
now, all your measurements are 63.28, 72.32, and 44.4
check your work by adding all the measurements together and setting that equal to 180.
63.28 + 72.32 + 44.4 = 180
180 = 180
since both sides are equal, all of the values are correct!
now that you know your work is correct, it is fully safe to say that the highlighted angle is 72.32 degrees.

9514 1404 393
Answer:
700
Step-by-step explanation:
You want to find x such that ...
1% of x = 7
0.01x = 7 . . . . . . . . . . use math symbols
x = 7/0.01 = 700 . . . . divide by the coefficient of x
1% of 700 is 7.

Step-by-step explanation:
A pet store sells goldfish and hermit crabs,
The store sells 7 goldfish and 3 hermit crabs for $26.
• The store sells 4 goldfish and 5 hermit crabs for $28.
How much would the store sell 6 goldfish and 4 hermit crabs for?
Answer:
[tex]Cost = \$28[/tex]
Step-by-step explanation:
Given
Represent Goldfish with g and hermit crabs with h.
The first statement, we have:
[tex]7g + 3h = 26[/tex]
The second statement, we have:
[tex]4g + 5h = 28[/tex]
Required
Determine the selling price of 6 goldfish and 4 hermit crabs
The equations are:
[tex]7g + 3h = 26[/tex] --- (1)
[tex]4g + 5h = 28[/tex] --- (2)
Make g the subject in (2)
[tex]4g + 5h = 28[/tex]
[tex]4g = 28 - 5h[/tex]
Divide both sides by 4
[tex]g = \frac{1}{4}(28 - 5h)[/tex]
Substitute [tex]\frac{1}{4}(28 - 5h)[/tex] for g in (1)
[tex]7g + 3h = 26[/tex]
[tex]7(\frac{1}{4}(28 - 5h)) + 3h = 26[/tex]
[tex]\frac{7}{4}(28 - 5h) + 3h = 26[/tex]
Multiply through by 4
[tex]4 * \frac{7}{4}(28 - 5h) + 4*3h = 26*4[/tex]
[tex]7(28 - 5h) + 4*3h = 26*4[/tex]
Open bracket
[tex]196 - 35h + 12h = 104[/tex]
[tex]196 -23h = 104[/tex]
Collect Like Terms
[tex]-23h = 104-196[/tex]
[tex]-23h = -92[/tex]
Make h the subject
[tex]h = \frac{-92}{-23}[/tex]
[tex]h = \frac{92}{23}[/tex]
[tex]h = 4[/tex]
Substitute 4 for h in [tex]g = \frac{1}{4}(28 - 5h)[/tex]
[tex]g = \frac{1}{4}(28 - 5*4)[/tex]
[tex]g = \frac{1}{4}(28 - 20)[/tex]
[tex]g = \frac{1}{4}(8)[/tex]
[tex]g = 2[/tex]
This implies that:
1 goldfish = $2
1 hermit crab = $4
The cost of 6 goldfish and 4 hermit crabs is:
[tex]Cost = 6g + 4h[/tex]
[tex]Cost = 6*\$2 + 4*\$4[/tex]
[tex]Cost = \$12 + \$16[/tex]
[tex]Cost = \$28[/tex]

It was recently estimated that homes without children outnumber homes with children by about 8 to 7. If there are 3870 homes in a county, how many of them are homes without children?
Answer: x = 2,340 homes without children
There are 2,340 homes without children.
Step-by-step explanation:
'x' represent the number of homes without children
'y' represent the number of homes with children
x : y = 9 : 7
Since the total number of homes is 4160 means x + y = 4160.
From x + y = 4160 follows y = 4160 - x.
Plug y = 4160 - x into x : y = 9 : 7
x : (4160 - x) = 9 : 7

Mr. Hamilton is making has p pages, and he plans to make 50 booklets.
Pick all the expressions that represent how much Mr. Hamilton will spend making the
booklets.
12.50p + 50.00
50(1.25p)
50(0.25p + 1.00)
12.50p + 50.00p
Answer:
50(1.25p) and 50(0.25p + 1.00)
Step-by-step explanation:
They both equal the same answer.
50(1.25p) = 62.5
50(0.25p + 1.00) = 62.5
when in parentheses, you multiply
50 * 1.25 = 62.5
50 * 0.25 + 1.00 = 62.5
The expression for the given scenario is 50(0.25p+1.00). Therefore, option A and C are the correct answers.
