The angle of BDC is 60 degrees.
The Angle Sum Property: What Is It?The angle sum property of a triangle states that the sum of a triangle's three internal angles is 180 degrees. A triangle is a closed figure made up of three line segments that have both internal and external angles. When the values of the other two angles are known, the measure of an unknown interior angle can be determined using the angle sum property.
The data listed above can be inserted into our diagram. ADB and BDC complement one another, therefore their combined degree measurement is 180. Thus, m∠ADB is equal to 180 – 60, or 120 degrees.
Given,
∠ADC = 59
∠BDC = ?
∠ADB = ∠BCD
∠BCD = 90
∠ADB = 90
∠ADC = 59
∠ADB + ∠BDC = 59
90 + ∠BDC = 59
∠BDC = -31

23. According to the Guinness Book of World Records, the world’s smallest horse is Thumbelina. Thumbelina is 42.5 cm tall and eats about 0.3 kg of food per day. A former world record holder ate food in the same proportion to its height. If it was 46.25 cm tall, how much did it eat? Give your answer to the nearest hundredth of a kilogram.
The food that the former world record holder should eat per day is 0.33kg.
How much should should the horse eat?The first step is to determine the ratio of the smallest horse's food per day to the height of the horse. This can be determined by dividing the food eaten per day by the height of the horse.
Division is the operation used in mathematics that is used to determine the quotient of two or more numbers
Ratio of the height and food eaten per day = 0.3 / 42.5
The next step is to multiply the ratio gotten in the previous step by the height of the former world holder
Food the former holder should eat = (0.3 / 42.5) x 46.25 = 0.33 kg

Write a function g whose graph represents the indicated transformation of the graph f.
f(x)=∣x+2∣−1; translation 1 unit to the right followed by a vertical stretch by a factor of 2 and a translation of 4 units down.
g(x) = ?
The transformed function is:
g(x) = 2*|x + 1| - 6
How to write the transformed function?
We start with the original function f(x), and we define the transformed function as g(x).
First, we have a translation of 1 unit to the right, so we have:
g(x) = f(x - 1)
Then, we have a vertical stretch by a factor of 2.
g(x) = 2*f(x - 1)
A translation of 4 units down:
g(x) = 2*f(x - 1) - 4
And we know that f(x) = |x + 2| - 1
Replacing that, we get:
g(x) = 2*( |x -1 + 2| - 1) - 4
g(x) = 2*|x + 1| - 2 - 4
g(x) = 2*|x + 1| - 6

A = 10% alcohol solution
B = 55% alcohol solution
we know we have 75 mL of A, that means A itself since it's 10% alcohol, really only has 75 * (10/100) = 7.5 mL of alcohol, likewise the B solution has say "x" mL, so alcohol wise it only has "x" * (55/100) = 0.55x, and we have a final mixture we need of say "y" mL at 30% alcohol.

[tex]\begin{gathered} F=\frac{9}{5}C+32_{} \\ C=100^{\circ} \\ F=\frac{9}{5}(100)+32=180+32 \\ F=212^{\circ} \end{gathered}[/tex]Therefore, the first option is the correct answer (212 degrees Fahrenheit & 100 degrees Celsius)

The maximum number of 14 hours that the crane is Used.
Step: 1 According to the question
1500 + (250)h ≤ 5000
1500 + 250h ≤ 5000
Step: 2

Van graphed f(x) = x and h(x) = f(x-10) on
the same grid. Which is not a true statement about the graphs of the two functions?
A The lines have the same slope.
B The lines are parallel.
C The lines do not have the same x-intercept.
D h(x) is located 10 units left of f(x).
Answer:
Step-by-step explanation:
"D" would be the correct answer. "f(x-10)" means that the "10" would be moving right-- the positive direction. Therefore, h(x) would be located 10 units RIGHT of f(x), which passes through the origin, (0,0). Statement A is correct because, on a graph, you'd have line f(x) passing through the origin, and towards the right, 10 units, (positive) you would have h(x) making them identical. So yes, same slope. Statement B is also correct, they're obviously parallel if they're beside each other. Statement C is correct as well. Although they're parallel, they don't share the same X-intercept. f(x)'s x-intercept would be (0,0), origin. h(x)'s x-intercept would be (10,0). These three statements, A,B, & C are correct statements therefore they're not our answers since we're looking for the incorrect statement....... STATEMENT D!
Submit a 250 word minimum essay on the steps of solving for both the x and y intercept.
The essay will need to be in your own words of course, but the basic idea is to replace x with 0 and solve for y to get the y intercept. To get the x intercept, replace y with 0 and solve for x.
Here's an example
2x+5y = 10
Let's find the x intercept
2x+5y = 10
2x+5(0) = 10
2x = 10
x = 5 is the x intercept
Now we'll do the y intercept
2x+5y = 10
2(0)+5y = 10
5y = 10
y = 10/5
y = 2 is the y intercept
The x intercept is the location where the graph crosses the x axis. The y intercept is where the graph crosses the y axis.

A boat traveled 240 miles downstream, then 240 miles back upstream. The trip downstream took 20 hours. The trip back upstream took 60 hours. Use this information to fill in the following blanks. Note: Express your answers as integers.
The boat is moving at 2 miles per hour and current is 4 miles per hour.
In calm water, the boat travels at a 2 mph pace.
4 miles per hour is the current's speed.
One such computation is as follows.
Let a be a representation of the boat's speed.
Allow b to be the current's speed.
20(a + b) = 240, according to equation 1.
Equation 2: 60(a + b)
Equation 3: a + b = 12
Equation 4: a - b Equals 4.
Equation 3 and equation 4 combined
(a + b) + (a - b)= 12+4
2x = 16
a= 16/2
a= 8
Calculate equation 4 minus equation 3
(a + b) - (a-b)= 12-4
2b= 8
b= 8/2
b= 4
As a result, the boat is moving at 2 miles per hour, while the current is moving at 4 miles per hour.

A rectangle is shown below.
measurements are to the nearest cm.
17 cm
9 cm
Calculate the lower bound for the area of the rectangle.
Calculate the upper bound for the perimeter of the rectangle
Answer:
lower bound for area = 140.25 square cm
upper bound for perimeter = 54 cm
======================================================
Explanation:
L = length
W = width
The unknown length L is rounded to the nearest cm to get to 17
This means it's in the interval [tex]16.5 \le L < 17.5[/tex]
The smallest it can get is L = 16.5 since that rounds to 17
It doesn't reach 17.5 since that would round to 18. But it could be L = 17.49 or L = 17.499 or L = 17.4999 and so on.
Similarly, if the unknown width W rounds to 9 cm, then its unrounded value is somewhere in the interval [tex]8.5 \le W < 9.5[/tex]
------------------------
Select the lower bounds of L and W to compute the lower bound of the area
length*width = L*W = 16.5*8.5 = 140.25
The smallest area possible is 140.25 square cm.
--------------------------
Use the upper bounds of each L and W to find the upper bound of the perimeter.
P = 2(L+W)
P = 2(17.5 + 9.5)
P = 54
In the previous example, we could have a true area of 140.25 square cm. However in this case, there's no way to reach this upper bound 54 itself. This is the so called "ceiling" which we can think of as an electric fence or asymptote value.
We could have the following example perimeter values that approach 54 but not actually reach it
perimeter = 53.9perimeter = 53.99perimeter = 53.999perimeter = 53.9999and so on.
A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing) and variable costs (such

per book. With the other method, the one-time fixed costs will total $12,209, and the variable costs will be $23.75 per book. For how many books produced will
the costs from the two methods be the same?
Step-by-step explanation:
for both costs to be the same, the sum of the fixed and the variable costs must be the same.
so,
49631 + 10.25x = 12209 + 23.75x
37422 = 13.50x
x = 37422 / 13.5 = 2,772
the costs of both methods will be the same for 2,772 produced books.

Therefore, the car is 10 feet long and the model is 8 inches long.
Hence, the ratio of the length of the car to the length of the model can be calculated as follows:
10 ft = 120 inches
Hence,
120 inches : 8 inches
