International system of unit (SI unit) are standard units which are universally accepted. There are 7 basic SI units which are meter (m), second (s), kilogram (kg), mole (mol), ampere (A), candela (cd) and kelvin (K).
The SI unit of flow rate is the m³/s.
The conversions needed are:
1 minute = 60 seconds,
1 cm³ = 1 ml = 0.001 ml,
1000000 cm³ = 1 m³,
1 L = 0.001 m³
We have to convert 5.0 liters of blood per minute. to m³/s. Therefore:
[tex]5\ L/minute=\frac{5\ L*0.001\ m^3}{1\ min*60\ s}=8.33*10^{-5} \ m^3/s[/tex]

Step-by-step explanation:
(i) Sum the forces at point M in the x direction.
∑F = ma
-T sin 30° − T sin 30° + 5 N = 0
2T sin 30° = 5 N
T = 5 N
(ii) Sum the forces on the ring in the x direction.
∑F = ma
T sin 30° − N = 0
N = 2.5 N
Sum the forces on the ring in the y direction.
∑F = ma
T cos 30° − mg − Nμ = 0
Nμ = T cos 30° − mg
2.5 μ = 5 cos 30° − 2
μ = 0.932
(iii) Sum the forces on the ring in the y direction.
∑F = ma
T cos 30° − m₁g − m₂g + Nμ = 0
m₂g = T cos 30° − m₁g + Nμ
m (10) = 5 cos 30° − 2 + (2.5)(0.932)
m = 0.466 kg

suppose a certain brand of smoke detector functions properly 85 percent of the time. i installed 3 of thse in my room, what is probability that at least one of the three smoke detectors functions propoerly
Answer:
The probability that at least one of the three smoke detectors functions properly = 0.996625
Step-by-step explanation:
Given that:
a certain brand of smoke detector functions properly 85 percent of the time
Let X represent the certain brand of smoke detector
X = 85%
X = 0.85
Let the probability that at least one of the three smoke detectors functions properly be P(Y)
P(Y) = 1- (1 - X)³
P(Y) =1 - (1 - 0.85)³
P(Y) = 1 - 0.003375
P(Y) = 0.996625
∴
The probability that at least one of the three smoke detectors functions properly = 0.996625

Step-by-step explanation:
An urn contains
Red balls = 8
White balls = 6
Green balls = 4
Total number of balls = 18 balls
(a) The probability that all four balls are red is?
The probability that a ball drawn is red = 8/18
The probability of drawing a ball that is not red = 1 - 8/18 = 10/18
The probability that all the 4 balls drawn are red = 8/18 × 7/17 × 6/16 x 5/15
= 1680/73440
= 0.022875817
Approximately = 0.023

Answer:
the total installment is $936 the carrying charges are $186 the monthly rate to buy the items are 19.23 or 20 monthsStep-by-step explanation:
$39 for 24 months comes to ...
$39 × 24 = $936
The "carrying charges" are the difference between the cash price and the installment price:
$936 -750 = $186
Saving at the rate of $39 per month, it would take ...
$750/$39 = 19.23 months about 20 months to save up the cash price.
Often, such savings would come from a once-a-month paycheck, so it would take more than 19 such paychecks to save the required amount.

Use the given data to find the minimum sample size required to estimate a population proportion or percentage.
Margin of error 0.03: confidence level 95%; and unknown
Answer:
1067
Explanation:
The formula that will be used to calculate the sample size if population proportion isn't given is expressed as;
Sample size n = |Z|² × 0.25/E² where;
Z is the z-score at 95% confidence
E is the margin of error
Given parameters
Z score at 95% confidence interval = 1.96
E = 0.03
Substituting the given values into the formula to get the sample size n we will have;
n = 1.96²×0.25/0.03²
n = 3.8416×0.25/0.0009
n = 0.9604/0.0009
n = 1067.11
n ≈ 1067
Hence, the minimum sample size required to estimate a population proportion is approximately 1067

You need to construct an open-top rectangular box with a square base that must hold a volume of exactly 475 cm3. The material for the base of the box costs 8 cents/cm2 and the material for the sides of the box costs 6 cents/cm2. The dimensions for a box that will minimize the cost of the materials used to construct box are:
Answer:
The dimensions of the box are:
x = 8,93 cm and h = 5,95 cm
C(min) = 850,69 cents
Step-by-step explanation:
The volume of the box is:
V = x²*h where x is the side of the square base and h the height
then h = V/ x² ⇒ h = 475 / x²
The total cost of box C is:
C = C₁ + 4*C₂ Where C₁ and C₂ are the costs of the base and one lateral side respectevily
Then cost C = 8*x² + 4* 6*h*x
The cost C as a function of x is
C(x) = 8*x² + (24* 475 /x² )*x
C(x) = 8*x² + 11400/x
Tacking derivatives on both sides of the equation
C´(x) = 16*x - 11400/x²
C´(x) = 0 ⇒ 16*x - 11400/x² = 0
16*x³ = 11400 ⇒ x³ = 11400/16
x³ = 712,5
x = 8,93 cm
and h = 475 / (8,93)² ⇒ h = 5,95 cm
C(min) = 8*79,77 + 4* ( 8,93)*5,95
C(min) = 638,16 + 212,53
C(min) = 850,69 cents
To check if value x = 8,93 would make C(x) minimum we go to the second derivatives
C´´(x) = 16 + 22800/x³ > 0
Then we have a minimum of C at x = 8,93

The temperature on Monday was 5 Degrees. The temperature on Thursday was - 8 degrees. Was the overall change in the temperature positive, negative, or 0? Why ? *
Answer:
Negative change
Step-by-step explanation:
Given
[tex]Monday\ Temperature = 5\ deg[/tex]
[tex]Thursday\ Temperature = -8\ deg[/tex]
First, we need to calculate the overall change in temperature
This is calculated by subtracting the initial temperature from the final temperature
[tex]Overall\ Change = Thursday\ Temperature - Monday\ Temperature[/tex]
[tex]Overall\ Change = -8\ deg - 5\ deg[/tex]
[tex]Overall\ Change = -13\ deg[/tex]
The overall change shows a negative change in the temperature.
This is as a result of a drop in temperature from Monday to Thursday
The area of rectangular is 46 square inches.if the length is 4 times the width . Then find the dimensions of the rectangular
Answer:
the rectangle's width is approximately 3.39 inches
and the length is approximately 13.56 inches.
Step-by-step explanation:
Recall that the area of a rectangle is Length times Width
If we name the length "L" and the width "W", we have:
L * W = 46
Also: "the length is 4 times the width" can be written in math form as:
L = 4 * W
and now we can replace the length L by 4 * W in the formula for the area:
[tex]L\,*\,W = 46\\(4\,W) \,W = 46\\4\,W^2=46\\W^2=\frac{46}{4} =11.5\\W=\sqrt{11.5} \\W\approx 3.39[/tex]
and now we find the value of L:
[tex]L=4\.(3.39) = 13.56[/tex]
Therefore, the rectangle's width is approximately 3.39 inches
and the length is approximately 13.56 inches.
The density of an object has the equation d = m/v. If an object has a mass of 20 g and a volume of 3.5 cm^3, what is its density?
Answer:
[tex]\Large \boxed{\mathrm{5.71 \ g/cm^3 }}[/tex]
Step-by-step explanation:
[tex]\sf \displaystyle density = \frac{mass}{volume}[/tex]
[tex]\displaystyle \rho = \frac{m}{V}[/tex]
[tex]\sf Mass \rightarrow 20 \ g \\ Volume \rightarrow 3.5 \ cm^3[/tex]
[tex]\displaystyle \rho = \frac{20}{3.5}[/tex]
[tex]\rho \approx 5.71[/tex]
Density is defined as the mass per unit volume of an object and It is calculated using the equation: density (d) = mass (m) / volume (v).
In this scenario, the mass of the object is given as 20 grams and the volume is given as 3.5 cm^3. To find the density, we can substitute these values into the equation: density =[tex]20 g / 3.5[/tex] cm^3 To simplify the unit of the measurement, we can convert cm^3 to mL (since 1 cm^3 is equal to 1 mL).
Thus, the equation becomes: density = [tex]20 g / 3.5[/tex] mL Calculating the division: density ≈ 5.71 g/mL Therefore, the density of the object is approximately 5.71 g/mL.

8% decrease
9% increase
9% decrease
8% increase
Answer:
I Think its 8% decrease
Answer:
The answer is
8% decreaseStep-by-step explanation:
To find the percentage change we use the formula
[tex]Percentage \: \: change = \frac{change}{original \: quantity} \times 100[/tex]
To find the change subtract the lesser one from the larger one
Original price = $ 52
Current price = $ 47.82
Change = 52 - 47.82 = $ 4.18
Substitute the values into the above formula
Percentage change is
[tex] \frac{4.18}{52} \times 100[/tex]
We have the final answer as
Percentage change = 8%
Since the current price was lesser than the original price there is a percentage decrease in the amount
