The scale blueprint of a rectangular pool is drawn 1/8 in - 1 foot. If the pool is 34 feet long, what is the measure of the pool's length on the blueprint
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
Blueprint's length = 34 x 1/8 = 4.25

Answer:
4r^2
Step-by-step explanation:
The area of a square is the square of the side length. Since a circle with radius r is inscribed inside the square, the side length of the square is 2r. Therefore, the area of the square is (2r)^2, which is 4r^2.
Note that the area of the circle is [tex]\pi r^2[/tex].

Answer:
146 degrees
Step-by-step explanation:
The sum of internal angles of any quadrilateral is always 360 degrees. This means x is 360 - (107 + 49 + 58), which is 360 - 214, which equals 146.
200 + 20x ≥ 500 I don't get these
Answer:
x ≥ 15
Step-by-step explanation:
200 + 20x ≥ 500
To solve this inequality, you must first subtract 200 from 500.
500 - 200 = 300.
Lastly, divide 300 by 20.
20x = 300
300 ÷ 20 = 15
Therefore, the value of x is 15.
Answer:
x ≥ 15
Step-by-step explanation:
1. So first of all we can simplify both sides now turning this into 20x+200≥500
2. Next we go ahead and subtract 200 from both sides because that is the opposite of adding, so something like this:
20x + 200 ≥ 500
-200 -200
This equals to:
20x ≥ 300
Now so x can be cancled we will need to divide by 20 because that is the opposite of multiplying(When it shows the x next to a number like this 20x it means that they are multiplyin):
20x ≥ 300
20 20
Now we cance out the left side(x) equaling up to this:
x ≥ 15

Answer:
34.3
Step-by-step explanation:
Answer: The answer is (34.3)
Step-by-step explanation:
Since you're rounding to the nearest tenth, you gotta look at the hundreds place which is 8. 8 rounds up so therefore, 2 rounds up and becomes 3. Which gives you the answer (34.3)

Dr. Spruill conducted a one-way ANOVA on a set of data examining political opinions after participants watched different propaganda footage from different eras. Each condition saw a different reel of footage and one condition simply watched a movie with no political agenda. Dr. Spruill's one-way ANOVA yielded significant results, but it was not able to tell him where the specific difference existed. Dr. Spruill will need to follow-up with which analysis to test all possible combinations of the conditions?
a. post-hoc analyses
b. factorial analysis
c. independent sample t-test
d. planned contrasts
Answer:
a. post-hoc analyses
Step-by-step explanation:
Post-hoc analyses refers to the analyses done after the complete study is accomplished and the conclusion is derived. After the derivation of the conclusion, the data are observed that whether or not they were specified previously. The data that is already collected is analyzed and new analysis is made out of thee data. The previous data is used for new analyze and new objective.
In the given situation, Dr. Spruill should follow post-hoc analyses to test all the possible combinations that can be derived from the given conditions.
derivative of
[tex] \frac{ {3x}^{2} - 2x - 1 }{ {x}^{2} } [/tex]
Show a step.
Answer:
[tex] \displaystyle \frac{dy}{dx} = \frac{2x + 2}{x^3} [/tex]
Step-by-step explanation:
we would like to figure out the derivative of the following:
[tex] \displaystyle \frac{ { 3x }^{2} - 2x - 1 }{ {x}^{2} } [/tex]
to do so, let,
[tex] \displaystyle y = \frac{ { 3x }^{2} - 2x - 1 }{ {x}^{2} } [/tex]
By simplifying we acquire:
[tex] \displaystyle y = 3 - \frac{2}{x} - \frac{1}{ {x}^{2} } [/tex]
use law of exponent which yields:
[tex] \displaystyle y = 3 - 2 {x}^{ - 1} - { {x}^{ - 2} } [/tex]
take derivative in both sides:
[tex] \displaystyle \frac{dy}{dx} = \frac{d}{dx} (3 - 2 {x}^{ - 1} - { {x}^{ - 2} } )[/tex]
use sum derivation rule which yields:
[tex] \rm\displaystyle \frac{dy}{dx} = \frac{d}{dx} 3 - \frac{d}{dx} 2 {x}^{ - 1} - \frac{d}{dx} {x}^{ - 2} [/tex]
By constant derivation we acquire:
[tex] \rm\displaystyle \frac{dy}{dx} = 0 - \frac{d}{dx} 2 {x}^{ - 1} - \frac{d}{dx} {x}^{ - 2} [/tex]
use exponent rule of derivation which yields:
[tex] \rm\displaystyle \frac{dy}{dx} = 0 - ( - 2 {x}^{ - 1 -1} ) - ( - 2 {x}^{ - 2 - 1} )[/tex]
simplify exponent:
[tex] \rm\displaystyle \frac{dy}{dx} = 0 - ( - 2 {x}^{ -2} ) - ( - 2 {x}^{ - 3} )[/tex]
two negatives make positive so,
[tex] \displaystyle \frac{dy}{dx} = 2 {x}^{ -2} + 2 {x}^{ - 3} [/tex]
further simplification if needed:by law of exponent we acquire:
[tex] \displaystyle \frac{dy}{dx} = \frac{2 }{x^2}+ \frac{2}{x^3} [/tex]
simplify addition:
[tex] \displaystyle \frac{dy}{dx} = \frac{2x + 2}{x^3} [/tex]
and we are done!
ABC city residents vote on construction of a new playground. The number of votes in favor of playground was 3500
and the votes against it were 1500. What percent of the votes were in favor of building a new playground?
NEED ASAP
Answer:
70% in favor of building a new playground
3500 (in favor) + 1500 (against it) = 5000 (total number votes)
3500 (in favor) 1500 (against it)

The boat top speed was 2 miles per hour less then 3/5 the cars top speed. The boats top speed was 73 miles per hour.what was the top speed of the car ?
Answer:
Word Problem. Hmm
The Interpretation of the first expression
Let boat top speed be x and car's top speed be y
x= 3y/5 – 2
From the question
x= 73miles per hr
73= 3y/5 - 2
3y/5 = 73+2
3y/5=75
y= 75x5/(3)
y=125miles per hr.
This is the car's top speed. Thanks
