Answer:
The number of drips per minute needed to deliver the medication at the prescribed dosage is 50 drips per minute
Step-by-step explanation:
The given parameters are;
The volume of the prescribed medication to delivered through IV = 800 mL
The duration over which the drug is to be delivered = 8 hours
The rate at which the IV delivers the medication = 30 drips/1 mL
800 mL = 800 × 1 mL
Therefore, the total number of drips in 800 mL= 800 mL × 30 drips/mL = 24,000 drips
The rate at which the drug is delivered = 800 mL/(8 hours) = 100 mL/hr = 100/60 mL/minute = 10/6 mL/minute
The total number of drips in 10/6 mL= 10/6 mL × 30 drips/mL = 50 drips
∴ The rate at which the medication needs to be delivered = 10/6 mL/minute = 50 drips/minute
The number of drips per minute needed to deliver the medication at the prescribed dosage of 800 mL/(8 hours) = 10/6 mL/minute = 50 drips per minute.

Step-by-step explanation:
A supermarket sells corn flakes for $3.60 per box. If the markup on the cereal is 30%, how much did the supermarket pay for each box?
I know the answer is 2, but can you show me how to get it. 40 Points!
Answer:
See below.
Step-by-step explanation:
So, here's how to break it down. Percentages can be turned into decimals, and vice versa, so we shall change 30% in 0.3. Next, we multiply 3.60 by 0.3. giving us 1.8. we subtract 1.8 from 3.6 and we are left with 1.8, which can be rounded up to two. I'm not sure where 2 came from other than estimation, but I did the math and got 1.8.
Zane and his favorite geometry student, , have just set sail for a day of fun on lake Erie. A spring squall quickly forms and catches you off guard, leaving you adrift on the lake. Zane suddenly discovers he has an irrational fear of water and is reduced to hugging the mast. You hear Sherman barking from the top of a lighthouse to help guide you to shore. In order to save Zane and yourself, you must calculate how far away you are from this lighthouse. Using a range finder, you expertly measure the distance from the sailboat to the top of the lighthouse at 350 yards.
angle B is 40 degrees.
(a) Based on the above information, find the distance across the water from the sailboat to the island
where the lighthouse is standing. You can only use trigonometry to solve. You must show all work for
credit. Round your answer to the nearest whole number if needed.
(b)Calculate the height of the lighthouse. You can only use trigonometry or Pythagorean Theorem to
solve.
Water is the Adjacent of this right triangle. 350 yards is the length of the Hypotenuse. We have given angle B, 40 degrees.
_________________________________________________________
According to SOH CAH TOA, we use CAH (cosineΘ = adjacent/hypotenuse).
Θ = 40hyoptenuse = 350adjacent = xcosine40 = x/350
[multiply both sides by 350]
350 · cosine40 = x
[put calculator in degree mode]
x ≈ 268 yards
So, the distance across the water from sailboat to the island is 268 yards.
_________________________________________________________
Let's use pythagorean theorem since we already know the adjacent and hypotenuse to find the opposite (opposite is also known as height).
a^2 + b^2 = c^2
a = ? (opposite or height)b = 268 (adjacent)c = 350 (hypotenuse)a^2 + (268)^2 = (350)^2
a^2 + 71824 = 122500
a^2 = 122500 - 71824
a^2 = 50676
[square both sides]
[tex]\sqrt{a^2}[/tex] = [tex]\sqrt{50676}[/tex]
a = [tex]\sqrt{50676}[/tex]
a ≈ 225
So, the height, opposite, of the lighthouse is 225 yards.

ANSWER: a) 268 yards b) 225 yardshelppppppppppppppppp
Answer:
64 degrees.
Step-by-step explanation:
We are given that angle QRP is 32 degrees.
We are also given that angle PRS is 84 degrees.
Add those two angles to get the measure of angle QRS.
measure of angle QRS= 116 degrees.
Same-side interior angles are supplementary
So,
116+ angle PQR= 180
subtract both sides by 116.
PQR=64
Therefore the measure of angle PQR is 64 degrees.
I hope this helps
HELP!!! Find the measure of each angle.
Answer:
Step-by-step explanation:
This figure is called a cyclic quadrilateral. The vertices of all sides lie on a circle.
That's property one.
Property 2 is that the opposite angles add to 180 degrees.
6y - 4 + 5y - 3 = 180 is the y angles. Combine like terms.
11y - 7 = 180 Add 7 to both sides.
11y - 7 + 7 = 180 + 7
11y = 187 Divide by 11
y = 187/11
y = 17
H = 17 * 6 - 4
H = 102 - 4
H = 98
F = 5y - 3
F = 5*17 - 3
F = 85 - 3
F = 82
=====================
11x + 8 + 8x + 1 = 180
19x + 9 = 180
19x = 171
x = 171/19
x = 9
E = 9*11 + 8
E = 99+8
E = 107
G = 8*9 + 1
G = 72 + 1
G = 73

The central angle of arc ST is 70 degrees. What is the measure of an inscribed

Answer:
35
Step-by-step explanation:
The measure of an inscribed angle whose endpoints are points S and T will be 35°.
What is a circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
The central angle is double the angle at the periphery that was subtended by the same chords.
The central angle of arc ST is 70°.
The measure of an inscribed angle whose endpoints are points S and T is given by the half of the central angle of arc ST. Then we have
Inscribed angle = 70° / 2
Inscribed angle = 35°
The measure of an inscribed angle whose endpoints are points S and T will be 35°.

Answer:
Centre = (2, -3)
radius = 5units
Step-by-step explanation:
The standard form of a circle is expressed as;
x²+y²+2gx+2fy+c = 0
Centre = (-g, -f)
radius r = √g²+f²-c
Given the equation;
x²+y²-4x+6y-12 = 0
Compare
2gx = -4x
2g = -4
g = -2
Similarly;
2fy = 6y
2f = 6
f = 3
Centre = (-(-2), -3)
Centre = (2, -3)
Radius = r = √(-2)²+3²+12
r = √4+9+12
r = √25
r = 5 units

Step-by-step explanation:
An encyclopedia has 30 volumes. The total weight of these volumes is 71 and 1/4 pounds. The average weight of a volume is 2.375.
What is the interpretation of average?Arithmetic mean is the best central measure available for representing the values of a data set. It is also called the average of the values of the considered data set.
It serves as the predicted value(in case no other information of the data is available) of that data set.
Average provides ill information in case of skewed data.

Good luck ^_^
The value of x in the triangle is 12/7.
We have,
Using the Midsegment theorem.
The midsegment is half the base of the triangle.
Now,
2x - 7 = 1/2 x 10
2 (2x - 7) = 10
14x - 14 = 10
Add 14 on both sides.
14x = 10 + 14
14x = 24
Divide 14 on both sides.
x = 24/14
x = 12/7
Thus,
The value of x in the triangle is 12/7.

Answer:
Part 1: It is not a valid conclusion to say that track and field sports are more popular than soccer based on the survey. The survey was taken at a track and field event so the people that were surveyed are probably biased.
