Rounded to the nearest tenth, what is the perimeter of rectangle ABCD?
A.
48.3 cm
B.
54.6 cm
C.
60.0 cm
D.
173.2 cm
Answers
54.6 cm
Step-by-step explanation:Hi there !
T30° => AD = AC/2 = 20cm/2 = 10 cm
T.Phytagoras
CD = √AC² - AD²
= √20² - 10²
= √400-100
= √300
= 10√3
= 10×1.73
= 17.3 cm
P = 2AD + 2CD
= 2×10cm + 2×17.3cm
= 20cm + 34.6cm
= 54.6 cm
Good luck !

According to one source, the average cumulated college student loan debt for a graduating senior is $29,400. Assume that such debt is normally distributed and that the standard deviation is $5,684. Thirty percent of these graduating seniors owe more than what amount?
Answers
Answer:
$32378.416
Step-by-step explanation:
We are asked to find: Thirty percent of these graduating seniors owe more than what amount.
More than 30% = Finding the z score of the 70% percentile.
The z score = 0.524
Hence, using z score formula:
z = (x-μ)/σ
0.524 = x - $29,400/$5,684
0.524 × 5684 = x - 29400
2978.416 = x - 29400
x = 29400 + 2978.416
x = $32378.416
Therefore, Thirty percent of these graduating seniors owe more than what amount $32378.416.

Answers
9514 1404 393
Answer:
8 units
Step-by-step explanation:
Displacement is the area under the velocity curve. The area of interest is in the shape of a trapezoid, so we can use the formula ...
A = (1/2)(b1 +b2)h
to find the area.
Here, b1=3, b2=1, h=4, so the area is ...
A = (1/2)(3 +1)(4) = 8
The displacement is 8 units in the time from t=1 to t=4.

Step-by-step explanation:
A ketchup company regularly receives large shipments of tomatoes. For quality control purposes, they take a sample of tomatoes from each shipment. If the sample shows convincing evidence that more than 8\%8%8, percent of the tomatoes in the entire shipment are bruised, then the company will request a new shipment of tomatoes. So the company tests H0 : p = 0.08 versus Ha : p > 0.08H, where p is the proportion of tomatoes in the entire shipment that are bruised.
One day, a supervisor takes a random sample of 600 tomatoes from a shipment and finds that 53 of the tomatoes are bruised, which results in a test statistic of z ≈ 0.75. Assuming that the necessary conditions are met, what is the approximate P-value associated with the significance test for this shipment?
Answers
Answer:
The value is [tex]p-value = 0.22663[/tex]
Step-by-step explanation:
From the question we are told that
The proportion of bruised tomatoes p = 0.08
The null hypothesis is [tex]H_o : p = 0.08[/tex]
The alternative hypothesis is [tex]H_a : p > 0.08[/tex]
The sample size is n = 600
The number of bruised tomatoes from the sample selected is k = 53
The test statistics is z =0.75
Generally the p-value is mathematically represented as
[tex]p-value = P(Z > z)[/tex]
=> [tex]p-value = P(Z > 0.75)[/tex]
From the z-table
[tex]P(Z > 0.75) = 0.22663[/tex]
So
[tex]p-value = 0.22663[/tex]
Answer:
P-value ≈ 0.2266

!well what I did. You know that 60 minutes=one hour. So I put 2 & 1/2 over 60.
Make 2 & 1/2 a improper fraction=5/2.
So 5/2 over 60
Then divide. 5/2 divided by 60 ( which is 60/1)
Then leave change flip, meaning leave the 5/2 change the division sign to multiplication, and flip, which you would flip 60/1 to 1/60
So we have 5/2 times 1/60. Multiply across. 5 times 1= 5. 2 times 60=120
So we have 5/120
Now we simplify 120 divided by 5 = 24. And 5 divided by 5 = 1
So 1/24

A well is 20ft deep. A snail at the bottom of the well climbs upto 4ft each day and slips back 2ft every night.how many days the snail to reach the too
Answers
Answer:
10 days
Step-by-step explanation:
4ft-2ft= so the snail moves 2ft every 24hrs
20ft÷2ft= takes the snail 10 days
Answer:
Defining Variables:
Let the number of days the snail takes to climb = x days
Total distance climbed in x days = x*4
Total distance slipped in x days = 2*x
Solving for the number of days:
Since the total distance the snail climbs is 20ft (depth of well)
The total distance climbed - total distance slipped = 20
replacing the variables
4x - 2x = 20
2x = 20
x = 10
Therefore, it will take the snail 10 days to reach the top

Step-by-step explanation:
∑₂°° (1 + c)⁻ⁿ
= ∑₂°° (1 / (1 + c))ⁿ
= ∑₁°° (1 / (1 + c))ⁿ⁺¹
This is a geometric series with a₁ = 1/(1+c)² and r = 1/(1+c).
The sum of an infinite geometric series is:
S = a₁ / (1 − r)
Therefore:
11 = 1/(1+c)² / (1 − 1/(1+c))
11 = 1 / ((1+c)² − (1+c))
11 ((1+c)² − (1+c)) = 1
11 (1 + 2c + c² − 1 − c) = 1
11 (c + c²) = 1
11c² + 11c − 1 = 0
c = [ -11 ± √(11² − 4(11)(-1)) ] / 22
c = (-11 ± √165) / 22
c cannot be between -2 and 0, so c = (-11 + √165) / 22.

Answers
Answer:
The delivery fee at the second store
Step-by-step explanation:
The x represents the delivery charge.
The cost for each potted plant at the second store is $7.50.
The delivery fee at the second store is $50.
The total cost of ordering potted plants at the second store is $270.
The number of sponsors of the entrepreneurship club is 36.
Given,
The entrepreneurship club is ordering potted plants for all 36 of its sponsors.
One store charges $8.50 for each plant plus a delivery fee of $20.
The equation 320 = x + 7.50(36) represents the cost of ordering potted
plants at a second store.
We need to find:
- what does the x represents
- the cost for each potted plant at the second store
- the delivery fee at the second store
- the total cost of ordering potted plants at the second store
- the number of sponsors of the entrepreneurship club
How do we represent a total cost with different charges and a number of items?If the number of items = M
Cost of each item = $N
Charges = P
Then the total cost can be represented by:
= M x $N + P
The charges are separated since it's an individual charges.
The exclusive total cost for the items is:
= Number of items x Cost of each item.
We have,
Number of sponsors = 36
One store:
Cost of each plant = $8.50
Delivery fee = $20
Second store:
320 = x + 7.50(36)
This equation represents the cost of ordering plotted plants from the second store.
Here,
x = delivery charges
Cost of each plotted plant = $7.50
The delivery fee at the second store:
320 = x + 7.50(36)
320 = x + 270
x = 320 - 270
x = $50
The total cost of ordering potted plants at the second store:
= 7.50 x 36
= $270
The number of sponsors of the entrepreneurship club:
= 36
Thus,
The x represents the delivery charge.
The cost for each potted plant at the second store is $7.50.
The delivery fee at the second store is $50.
The total cost of ordering potted plants at the second store is $270.
The number of sponsors of the entrepreneurship club is 36.
