Answer:
B) 2037
Step-by-step explanation:
using the problem an exponential equation can be made
7(1.045)× =25
--solve for x--
x=28.9
it will take 28.9 year for the price to get to $25 so add 2008 to 28.9 to get 2036.9
2037 is closest to 2036.9 so the answer is B

Answer:
23) x=20; y=10√3
24) x=4√2; y=8
25) x=12; y=3+6√3
Step-by-step explanation:
Recognize that all of the triangles involved here are one of the two "special" triangles. By previous use of the Pythagorean theorem, or your familiarity with the trig functions of the "special" angles 30°, 45°, 60°, you know the following side ratios:
45°-45°-90° triangle: 1 : 1 : √2
30°-60°-90° triangle: 1 : √3 : 2
Using these ratios, you can solve these figures "by inspection."
__
23) x = 2((10√2)/√2) = 20
y = √3((10√2)/√2) = 10√3
__
24) x = 4√2
y = (4√2)√2 = 8
__
25) x = 6·2 = 12
y = 3 +6√3 . . . . . 3 units more than the longer leg of the 6 : 6√3 : 12 triangle

A semicircle with diameter 8 inches is connected to a triangle with a base length of 8 inches. The height of the triangle is 3 inches. What is the area of the composite figure? (8π + 6) in.2 (8π + 12) in.2 (8π + 18) in.2 (8π + 24) in.2
Answer:
B or (8π + 12) in.2
Step-by-step explanation:
The area of the composite figure = (8π + 12) [tex]inch^{2}[/tex].
How to estimate the area of the composite figure?The composite figure is made up of a semicircle and an isosceles triangle.
The area of a semicircle = (1/2)π[tex]r^{2}[/tex]
radius = 4 inch
When we substitute, the area of the semicircle is
= (1/2)π[tex]\times[/tex]16
= 8π [tex]$inch^{2}[/tex]
Area of the isosceles triangle = (1/2)bh
= (1/2)(4+4)[tex]\times[/tex]3
= 12 [tex]inch^{2}[/tex]
We add the two areas to acquire the area of the composite figure to be: (8π + 12) [tex]inch^{2}[/tex]
The area of the composite figure = (8π + 12) [tex]inch^{2}[/tex].
Therefore, the correct answer is option b. (8π + 12) in.2

That's population of turtles in a lake is estimated at 1,000. The population projected to increase 12% per year.
Answer:
(1,000 * (100 + 12))/100 = 1,120 - 1,000 = 120 turtles/ per year
Step-by-step explanation:
The exponential function which can be use to identify the monthly growth is,
⇒ y = 1000 (1.12)¹²ⁿ
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
We have to given that;
That's population of turtles in a lake is estimated at 1,000.
And, The population projected to increase 12% per year.
Hence, The exponential function which can be use to identify the monthly growth is,
⇒ y = 1000 (1 + 12/100)¹²ⁿ
⇒ y = 1000 (1 + 0.12)¹²ⁿ
⇒ y = 1000 (1.12)¹²ⁿ
Thus, The exponential function which can be use to identify the monthly growth is,
⇒ y = 1000 (1.12)¹²ⁿ

On the way home from her friend's house Sandy skateboards 30% of the way, walks 1/2 of the way, and then skips the rest of the way. Which decimal number shows the portion of the distance Sandy skips?
Answer:
0.2
Step-by-step explanation:
Convert the walking to percent
[tex]\frac{1}{2} \times 100 = 50[/tex]
Add both skateboarding and walking
[tex]30\% + 50\%\\\\= 30 + 50\\\\= 80[/tex]
Now, subtract that from a whole percent
[tex]100 - 80 = 20\\\\20\%[/tex]
Convert it to a decimal
[tex]20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2[/tex]
Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.

Step-by-step explanation:
Write the number in exponential form with the base of 2:

Since the bases are the same, set the exponents equals.
[tex]x - 3 = - 3[/tex]

The table gives the probabilities that orphaned pets in animal shelters in six cities are one of the types listed
The probability that a randomly selected orphan pet in an animal shelter in Austin is a dog is
%. The probability that a randomly
selected orphaned dog in the same animal shelter in Austin is a Chihuahua is
No
The probability that the Austin orphaned pet is a dog is 32.34%.
The probability that the Austin orphaned dog is a Chihuahua is 29.38%.
What are the probabilities?Probability determines the chances that an event would happen in a random event. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that an orphaned pet in an animal shelter in Austin is a dog = total number of dogs in Austin / total number of pets
(2.76 + 2.86 + 3.44 + 2.65) / (2.76 + 2.86 + 3.44 + 2.65 + 24.50) =
11.71/36.21 = 32.34%
The probability that an orphaned dog in the same animal shelter in Austin is a Chihuahua = total number of Chihuahua in Austin / total number of dogs in Austin
3.44 / 11.71 = 29.38%

What is the value of x? (3x + 50) Enter your answer in the box (6x - 10) X =
Answer:
x = 20
Step-by-step explanation:
(6x - 10) and (3x + 50) are vertical angles and are congruent, then
6x - 10 = 3x + 50 ( subtract 3x from both sides )
3x - 10 = 50 ( add 10 to both sides )
3x = 60 ( divide both sides by 3 )
x = 20
