Ms. Federman graded 5 papers in 40 minutes. At this rate, how many minutes will it take her to grade 30 papers?
Answer:
240 minutes
Step-by-step explanation:
If it's 40 minutes for just 5 papers, we need to figure how many minutes it would take to grade just 1. So you have to divide 40 by 5 which is 8. Then 8 time 30 which is 240.

Three radar sets, operating independently, are set to detect any aircraft flying through a certain area. Each set has a probability of 0.03 of failing to detect a plane in its area. Consider one of the radar sets. What is the probability that it will correctly detect exactly three aircraft before it fails to detect one, if aircraft arrivals are independent single events occurring at different times?
Answer:
[tex]Probability = 0.00002619[/tex]
Step-by-step explanation:
Given
Let d represents the event that a radar detects an aircraft.
So:
[tex]P(d) = 0.03[/tex]
Required: Determine the probability that a radar detects three before it fails to detect 1.
This event is represented as: d d d d'
And the probability is calculated as thus:
[tex]Probability = P(d) * P(d) * P(d) * P(d')[/tex]
Using complement rule:
[tex]Probability = P(d) * P(d) * P(d) * (1 - P(d))[/tex]
So, we have:
[tex]Probability = 0.03 * 0.03 * 0.03 * (1 - 0.03)[/tex]
[tex]Probability = 0.03 * 0.03 * 0.03 * 0.97[/tex]
[tex]Probability = 0.00002619[/tex]

Suppose a new regulation that a maximum angle of a ramp for a wheelchairs is 8°. At least how long must the new ramp be? Round to the nearest tenth of a foot.
Answer:
The length of the ramp is at least 17.2 feet
Step-by-step explanation:
See attachment for the appropriate diagram.
The length of the ramp is represented with z
So, we have:
[tex]\theta = 8[/tex]
[tex]BC = 2.4[/tex]
Required
Find z
To find z, we make use of sine formula:
[tex]sin\theta = \frac{BC}{z}[/tex]
Make z the subject
[tex]z= \frac{BC}{sin\theta }[/tex]
So:
[tex]z= \frac{2.4}{sin(8)}[/tex]
[tex]z= \frac{2.4}{0.1392}[/tex]
[tex]z= 17.2ft[/tex]
The length is at least 17.2 feet

What is the value of x to the nearest degree?
8
15
Answer:
x ≈ 62°
Step-by-step explanation:
By applying tangent rule in the given right angled triangle,
tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(x) = [tex]\frac{15}{8}[/tex]
tan(x) = 1.875
x = [tex]\text{tan}^{-1}(1.875)[/tex]
x = 61.93
x ≈ 62°
what is 6⅓ + 5 3/10 =
Answer:
11 19/30
Step-by-step explanation:
Given 6⅓ + 5 3/10
Convert to improper fraction
= 19/3 + 53/10
Find the LCM
= 19(10)+3(53)/30
= (190+159)/30
= 349/30
= 11 19/30
Hence the sum of the fractions is 11 19/30
(1) The tuition T for one year at a college can be approximated by the equation T = 1/8 + 9 where x is the year since 2000, and T is tuition in thousands of dollars. Use this equation to estimate the tuition for one year at this college in 2020.
Answer:
Step-by-step explanation:
I’m assuming you meant to write
T = ⅛x + 9
T = ⅛(20) + 9 = 11.5
The required estimate of tuition for one year at the college in 2020 is $11500
Given,
The tuition T for one year at a college can be approximated by the equation.
T = 1/8x + 9 - - - - - - (1)
where x is the year since 2000, and T is tuition in thousands of dollars.
Tuition fee in the year 2020 to be calcuate.
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
The expression is given, since 2000
so the change in years
x = 2020 - 2000
x = 20
Put this x in equation 1
T = 20/8 + 9
T = 2.5 + 9
T = 11.5
SInce t is in thousand so Tuition fee = $11,500.
Thus, the required estimate of tuition for one year at the college in 2020 is $11500

Kindred invested $38,976 into first company his investment decreased by 3.5% each years over the first 3 years. Which exponential decay model could use to determine the amount his investment will be worth if in continue to decrease at the same rate?
Answer:
35,025.08 x 0.965 ^ X = Y
Step-by-step explanation:
Given that Kindred invested $ 38,976 into First company, and his investment decreased by 3.5% each year over the first 3 years, to determine which exponential decay model could use to determine the amount his investment will be worth if it continues to decrease at the same rate the following calculation must be performed:
100 - 3.5 = 96.5
38,976 x 0.965 ^ 3 = 35,025.08
Thus, after 3 years of losses, the value of the account will be $ 35,025.08. In turn, if we wanted to determine the amount his investment will be worth if it continues to decrease at the same rate, the following equation should be applied:
35,025.08 x 0.965 ^ X = Y
In this case, X will be the number of years the investment has fallen, and Y will be the value of said investment after the years of decline.
