find the perimeter of the figure. round to the nearest tenth. numbers only. do not label.
The perimeter of the figure, rounded to the nearest tenth is: 17.2 units.
What is the Perimeter of a Figure?Perimeter of a figure is the total length of all sides of the figure.
The distance formula, [tex]d = \sqrt{(x_2 - x_2)^2 + (y_2 - y_1)^2}[/tex], can be used to find the length of each segment of a figure on a coordinate plane.
Thus, we have:
A(0, 4)
B(4, 4)
C(1, 0)
D(4, 1)
Perimeter of the figure = AB + BC + CD + DA
AB = |4 - 0| = 4 units
BC = √[(1−4)² + (0−4)²]
BC = √25
BC = 5 units
CD = √[(1−4)² + (0−1)²]
CD = √10
CD = 3.2 units
DA = √[(0−4)²+ (4−1)²]
DA = √25
DA = 5 units
Therefore:
Perimeter of the figure = 4 + 5 + 3.2 + 5 = 17.2 units.

In a cryptarithm, each letter is assigned its own unique digit. In the cryptarithm shown (where MATH is 3 times FUN), FUN is a 3-digit number with its digits in consecutive and increasing order. What 3-digit number is FUN? [No leading digit can be 0.]
The 3 digit number that is FUN is; 678
What is the combination of the numbers?We are told that MATH is 3 times the word "FUN".
We are also told that each letter is assigned a unique number and that no leading digit can be zero and that the digits must be consecutive.
Now, product of 789 by 3 gives;2367.
Each letter should have a unique letter and so that is not the correct sequence.
Let us try the product of 678 by;
678 * 3 = 2034
This fulfils the condition of the question because each letter has a unique digit, the lead digit is not zero and the numbers are consecutive numbers in increasing order.
Thus, the 3-digit number that is FUN is 678.

A couple plans to save for their child's college education. What principal must be deposited by the parents when their child is born in order to have $44,000 when the child reaches the age of 18? Assume the money earns 5% interest, compounded monthly.
Answer:
$17,922.55
Step-by-step explanation:
The future value of a one-time investment is calculated using the formula ...
FV = P(1 +r/n)^(nt)
where principal P is invested at annual rate r compounded n times per year for t years.
__
You have FV = 44000, r = 0.05, n = 12, t = 18, and you want to find P.
44000 = P(1 +0.05/12)^(12·18) ≈ 2.455008P
P = 44000/2.455008 = 17,922.55
The couple must deposit $17,922.55 in order to have $44,000 in 18 years.

A business owner opens one store in town A. The equation p(x)= 10,000(1.075)^ 5 represents the anticipated profit after t years. The business owner opens a store in town B six months later and predicts the profit from that store to increase at the same rate. Assume that the initial profit from the store in town B is the same as the initial profit from the store in town A. At any time after both stores have opened, how does the profit from the store in town B compare with the profit from the store in town A? 65% 96% 104% 154%
Answer:
It's 96%
Step-by-step explanation:
Just took the test
The profit from the store in town B compared with the profit from the store in town A is the ratio represented by 96%.
What is a ratio?The ratio is the simplest form of a fraction involving two quantities determining each other. It is written as a:b, read as "a is to b", and functions as a/b.
How to solve the question?In the question, we are given that a business owner opens one store in town A. The equation p(x)= 10,000(1.075)^t represents the anticipated profit after t years. The business owner opens a store in town B six months later and predicts the profit from that store to increase at the same rate.
We are asked to assume that the initial profit from the store in town B is the same as the initial profit from the store in town A and find the comparison between the profits from the store in town B to the store in town A.
We take the time for the store in town A as t1.
Then the time for the store in town B is t1 - 0.5, as store in town B is opened 6 months after the store in town A.
To compare the profits, we take the ratio of the profits from the stores.
= Profit from the store in town B/Profit from the store in town BA
= 10,000(1.075)^(t1 - 0.5)/10,000(1.075)^t1
= (1.075)^(t1 - 0.5 - t1)
= 1.075^(-0.5)
= 1/(1.075)^0.5
= 0.96448
= 96% (approx.)
Therefore, the profit from the store in town B compared with the profit from the store in town A is the ratio represented by 96%.

Use your result to find d when h= 500m.
The value of d when h is 500m is approximately 1,813m
How to find the height of the aircraftGive the heights above the ground (hm) after it has dropped expressed as:
h = 3/8(d-480),
If h = 500m, then;
500 = 3/8(d - 480)
Cross multiply
500*8 = 3(d - 480)
4000 = 3(d - 480)
Expand to have:
4000 = 3d - 1440
3d = 5440
d = 1,813.3m
Hence the value of d when h is 500m is approximately 1,813m

A beverage producer needs to minimize shipping costs from its two primary plants in Hamilton and Waterloo. All wholesale orders within the city are shipped from one of these plants. An outlet in Toronto orders 200 cases of soft drinks, on the same day an order for 240 cases comes from London. The plant in Hamilton has 300 cases ready to ship and the plant in Waterloo has 200 cases. The cost of shipping each case to Toronto is $0.50 from Hamilton, and $0.70 from Waterloo. The cost of shipping each case to London is $0.60 from Hamilton, and $0.65 from Waterloo. How many cases should be shipped from each warehouse to minimize costs?
Using the Least Cost Method, 200 cases should be shipped to Toronto from Hamilton and 100 cases from Hamilton to London with the remaining 140 cases shipped from Waterloo to London to complete the orders.
What is the Least Cost Method for solving transportation problems?The Least Cost Method is a method of solving transportation problems. The allocation starts by allocating with the cell or column with the minimum cost.
The lower-cost cells are first chosen over the higher-cost cells to obtain the least cost of transportation.
Data and Calculations:Toronto London
Demand 200 cases 240 cases
Inventory:Hamilton = 300 cases
Waterloo = 200 cases
Transportation Costs per case:Toronto London
Hamilton $0.50 $0.60
Waterloo $0.70 $0.65
Various Transportation Costs:Toronto London
Hamilton $100 (200 x $0.50) $144 (240 x $0.60)
Waterloo $140 (200 x $0.70) $156 (240 x $0.65)
The number of cases that should be shipped from each warehouse to minimize transportation costs is as follows:
Toronto London
Hamilton 200 cases 100 cases (at a total cost of $60)
Waterloo 0 case 140 cases (at a total cost of $91)
Total 200 cases 240 cases
Total transportation
costs $100 (200 x $0.50) $151 (100 x $0.60 + 140 x $0.65)
Thus, using the Least Cost Method, 200 cases should be shipped to Toronto from Hamilton and 100 cases from Hamilton to London with the remaining 140 cases shipped from Waterloo to London to complete the orders with the total transportation cost incurred for the two orders from Toronto and London as $251.
