cougar park is shaped like a parallelogram and has an area of 1/16 square mile. its base is 3/8. what is its height?
PLEASE I WILL DO ANYTHING JUST I NEED TO GET THIS LAST QUESTION DONE
ANSWER:
= 158 square inches
STEP BY STEP:
okay! so basically I like to ignore the net figure (just my personal opinion)
so we know that the rectangular prism has six sides (one top, one bottom, one front, one back, and two on each side)
so using that information, we can solve for the surface area!
FRONT AND BACK AREA:
- to solve for this area, we are going to take the 8" and multiply it by 5" to find the surface area of the front and the back panels
8*5 = 40 BUT WE HAVE TWO PANELS WITH THIS AREA
40*2 = 80
TOP AND BOTTOM AREA:
- to solve for this area, we are going to take 3" and multiply it by 8" to find the surface area of the top and bottom panels
3*8 = 24 BUT WE HAVE TWO PANELS WITH THIS AREA
24*2 = 48
SIDE AREA:
- to solve for this area, we are going to take 3" and multiply it by 5" to find the surface area of both the left and right sides
3*5 = 15 BUT WE HAVE TWO PANELS WITH THIS AREA
15*2 = 30
So now we have all of our areas and we will just add them together!
80+48+30
= 158 square inches
I hope this helped :)

ONLY answer if you know! Which of the following will have a negative result? (1 point)
O-8-(-10)
O 12-14
07-(-3)
simplify (0.01)^(-0.5)
Answer:10
Step-by-step explanation:
In fraction,
(1/100)^(-1/2)
Equivalent to 1/((1/100)^(1/2))
Power 1/2 is basically square root
So we have 1/(1/10) after applying square root to 1/100
so final step
1 divide (1/10) = 10

Answer: -15
Step-by-step explanation:
f(-8) is the value of y / f(x) when x = -8 in the function f(x)
f(-8) = -5
g(4) is the value of y / f(x) when x = 4 in the function g(x)
g(4) = 5
-1 * f(-8) - 4 * g(4)
Substitute -5 for f(-8) and 5 for g(4)
-1 * -5 - 4 * 5 (evaluate, note: remember order of operations)
5 - 4 * 5
5 - 20
-15
A piano teacher is interested in knowing how many of her students plan to take time off from lessons during the summer months. She surveys each student on Monday and determines that about 50% of her students plan to take time off.
She then repeats her study with her students on Tuesday, Wednesday, Thursday, and Friday. All surveys yield the same results. What generalization can the piano teacher make?
A.
The sample is biased; therefore, a generalization cannot be made regarding how many of her students plan to take time off this summer.
B.
About half of her students plan to take time off this summer.
C.
There is not enough information to generalize the survey results.
D.
Most of her students plan to take time off this summer.
Answer: B
About half of her students plan to take time off this summer.
Step-by-step explanation:
The generalization that can be made by the piano teacher is about half of her students plan to take time off this summer.
What is the generalization that can be made?A survey is when a particular group of people are asked about their preferences or opinion on a particular subject matter. The piano teacher asked students from the classes on Monday through to Saturday if they would take time off.
The result was that 50% of the students would take time off. Thus, it can be generalized that about half of her students plan to take time off this summer.

Jillian has a circular pool in her backyard with a diameter of 24 feet. What is the circumference of the pool rounded to the nearest tenth of a foot? Use 3.14 for
Answer:
75.36
Step-by-step explanation:
r = radius
pi = 3.14
You know the diameter (2*r) is equal to 24 feet
using the formula for diameter you get 2r = 24
now, you can either solve for r (radius) and plug radius into the formula for circumference OR you can use the 2*r value of 24 feet and plug that into the formula for circumference
if you solved for r directly, you would get r = 12
- then you plug r into the circumerference formula 2*pi*r (where pi 3.14) and you would get 75.36
if you used the diameter value of 2*r, all you would have to do is multiply the given diameter value by pi (3.14) and you would get 75.36
UNIT: feet
NOTE
- you can use the diameter value and simply multiply that by pi because the formula for diameter is 2*r and the formula for circumference is 2*r*pi

Answer:
2/3+2/3=4/3 or 1 1/3
Step-by-step explanation:
I figured it out!!
it should be greater than. the reasoning for this is if you equally split a rectangle into 3 pieces and then also split the same sized rectangle into equal pieces then which pieces would be bigger? the Rectanhle that is split into 3! this is because you have less pieces to split the rectangle into so the less you have too split the rectangle to larger the pieces are!!
Answer:
2/3+2/3 is greater than 1 1/4, so Edward does not have enough oil
Step-by-step explanation:
2/3+2/3=4/3, or 1 1/3
So now it's is 1 1/3 greater than or less than 1 1/4, which is just a matter of if 1/3 is greater than 1/4. 1/3 is 0.33 repeating, and 1/4 is 0.25, so 1/3 is greater than 1/4
1 1/4 is the amount of oil he has, and 1 1/3 is the amount required, which is more than he has so therefore he can't make 2 batches
x+y=-1 and x=y+19 solve for x
Answer:
X=9
Step-by-step explanation:
Deduce the minimum value of sinx+cosx and give the corresponding values of x, for x E [-360;360]
The minimum value of both sine and cosine is -1. However the angles that produce the minimum values are different, [tex]-\pi/2, \pi[/tex] for sine and cosine respectively.
The question is, can we find an angle for which the sum of sine and cosine of such angle is less than the sum of values at any other angle.
Here is a procedure, first take a derivative
[tex]\frac{d}{dx}(\sin x+\cos x)=\cos x -\sin x[/tex]
Then compute critical points of a derivative
[tex]\cos x-\sin x=0\implies x_1=\frac{\pi}{4},x_2=\frac{5\pi}{4}[/tex].
Then evaluate [tex]\sin x +\cos x[/tex] at [tex]x_1,x_2[/tex].
You will obtain global maxima and global minima [tex]\sqrt{2}, -\sqrt{2}[/tex] respectively.
The answer is [tex]-\sqrt{2}[/tex].

A cardboard box in the shape of a rectangular prism has the dimensions shown. Write a polynomial in standard form to represent the volume of the box.
Answer:
[tex]Volume = x^3 +3x^2 -16x +12[/tex]
Step-by-step explanation:
Given [missing from the question].
The dimensions are:
Length =(x + 6), Width = (x - 2) and Height = (x -1)
Required
Represent the volume as a polynomial
Volume is calculated as:
[tex]Volume = Length * Width * Height[/tex]
So:
[tex]Volume = (x + 6) * (x - 2) * (x - 1)[/tex]
Expand
[tex]Volume = (x + 6) * (x^2 -2x -x +2)[/tex]
[tex]Volume = (x + 6) * (x^2 -3x +2)[/tex]
Expand
[tex]Volume = x^3 -3x^2 +2x +6x^2-18x +12[/tex]
Collect like terms
[tex]Volume = x^3 -3x^2+6x^2 +2x -18x +12[/tex]
[tex]Volume = x^3 +3x^2 -16x +12[/tex]

Describe these points with a double inequality
These points can be described the following double inequality: -3≤x≤13.
InequalitiesInequality is a mathematical expression that does not present equality between both sides. It is represented by symbols: <, ≤, > and ≥.
When the variable x is between the both extremes, the inequality will be called double inequality. Therefore, the double inequality can be written in the form below .
a<x<b is equivalent to x>a and x<ba>x>b is equivalent to x<a and x>ba≤x≤b is equivalent to x≥a and x≤ba≥x≥b is equivalent to x≤a and x≥bAs the interval is represented by a closed dot, your interval inequality must be represented by signs ≤ or ≥.
Thus, the points of this question can be described as: -3≤x≤13.

Answer:
it is B
Step-by-step explanation:
he is putting in by the 3/5
Answer:
C.
Step-by-step explanation:
Why its C...
You can tell that on the top it say that the total is 15 so it can not be a. So now our answer choices are B, C, ad D.
Now it says that there are 3/5 highlighted but since the rest say 3/5 we can not eliminate yet.
Next we would multiply 3 x 3 to get 9 for how many dollars there are. Cross out B.
Between C and D, C is the most reasonable answer because it says how much did he put in the bank while the other one (D) says how much did he spend?
So it would be C
