Answers
Answer:
I have a parrot
I have an African grey parrot, his name is Yaco (pronounce the "a" in his name the same way you'd pronounce the "a" in taco lol). He's 23 years old and the species can normally live in the range of 50-85 years old! Yes! He does do things on his own, eat, drink, play, and talk. One question you asked is "Does he ever steal food?" No, but he's worse than the dog when it comes to begging for human foods and snacks, he can have quite a vary of human foods such as some fruits, nuts, and crackers and such. Also, he has about a 300 word vocabulary and with a wide range of different sounds and noises. And with him being a parrot, he's picked up all these words, phrases, and sounds from people and movies and pets that are always often around him and in our home. He has been around 7 years longer than me. He's a very neet and VERY smart bird. In your free time go onto you.tube and search up 'Einstein the talking african grey parrot' it'll give you an idea of their intelligence.

Answers
Answer:
3,848 feet.
Step-by-step explanation:
1) Square 70
2) Multiply 4,900 (the square of 70) by pi
3) Divide 15,393.804 (4,900 times pi) by 4 (to find a quarter of the tank)
4) Round 3,848.451 (15,393.804 divided by 4) to the nearest whole number and you get 3,848 feet.

PLS HELP I WILL REALY BE HAPPY IF YOU HELPED A window is being replaced with tinted glass. The plan below shows the design of the window. Each unit length represents 1 foot. The glass costs $13 per square foot. How much will it cost to replace the glass? Use 3.14 for π
Answers
Step 1 :
Separate the composite figure into simpler shapes as shown by the dashed lines : a rectangle, two semicircles with equal area (one is one the left side of the rectangle and other one is on the right side).
Step 2 :
Find the area the rectangle.
Length (l) = 5 ft
Width (w) = 4 ft
Use the formula.
A = lw
A = 5 · 4
A = 20 square ft
The area of the rectangle is 24 square feet.
Step 3 :
Find the combined area of two semi-circles.
Radius = 2 ft
Use the formula.
A = 2 x (1/2)πr2
A = πr2
A = (3.14)(2)2
A = (3.14)(4)
A = 12.56 square ft
The combined area of two semi circles is about 12.56 square ft.
Step 4 :
Find the area of the composite figure.
A = 20 + 12.56 = 32.56 square ft
Step 5 :
Calculate the cost of tinted glass for the window.
Total cost = Area · Cost per feet
Total cost = 32.56 · $28
Total cost = $911.68
So, the cost of tinted glass for the window is $911.68.

Answers
The correct null and the alternative hypotheses are:
[tex]h_0: \mu = 2.7\\\\ h_a: \mu < 2.7[/tex]
What is a hypothesis?A hypothesis is an untested statement in mathematics that is supported by all available data and numerous weaker results.
A "conjecture" is a mathematical statement that has not been proven.
The given data in the problem is;
n is the sample size = 40
μ is the population mean = 2.7
[tex]\rm \sigma[/tex] is the standard deviation= 0.2
[tex]\bar x[/tex] is the sample mean:= 2.3
It is found that the null hypothesis always shows the equality sign.
So for the null hypothesis;
[tex]h_0: \mu = 2.7[/tex]
It is observed that the sample mean is less than the population mean in that case, the alternate hypothesis will be;
[tex]h_a: \mu < 2.7[/tex]
Hence the correct null and the alternative hypotheses are:
[tex]h_0: \mu = 2.7\\\\ h_a: \mu < 2.7[/tex]

Which graph represents the function f(x) = x^2-25/x+5
Answers
Answer:
x= -5
Step-by-step explanation:
f(x) = [ x^2 - 25 ] / [ x + 5 ] = [ (x + 5) ( x- 5)] / [ x + 5 ] = x - 5
This will be the graph of f(x) = x - 5 with a "hole" at x = - 5
The graph of the rational function f(x) = (x² - 25)/(x + 5) is represented by the graph second option (B) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The equation of the rational function:
f(x) = (x² - 25)/(x + 5)
As we know, in the rational function the denominator cannot be zero.
x + 5 ≠ 0
x ≠ -5 (there will be a hole at x = -5)
f(x) = (x - 5)(x + 5)/(x + 5)
Because: a² - b² = (a - b)(a + b)
f(x) = (x - 5)
The above function represents the linear function.
The slope of the linear function is positive.
m = 1
The y-intercept of the linear function is c = -5
Thus, the graph of the rational function f(x) = (x² - 25)/(x + 5) is represented by the graph second option (B) is correct.

for the first equation to equal 4 the x must equal -6.
because something plus 7 had to equal 4. and we know that -3 + 7 equals 4. Now, -6 ÷ 2 equals -3 and that gives us the right answer.
So now plug -6 into the new problem so now it is

Nabil has 1000 cm³ of material. He uses 8.7 cm³ to make a right triangular prism. He wants to make a second prism that is a dilation of the first prism with a scale factor of 5. How much more material does Nabil need in order to make the second prism? Select from the drop-down menu to correctly complete the statement.
96.2
87.5
78.8
Answers
Answer:
96.2
Step-by-step explanation:
The material Nabil need in order to make the second prism is 87.5
How does dilation affect length, area, and volume of an object?Suppose a figure (pre image) is dilated (dilated image) by scale factor of k.
So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:
L = k × M
where 'k' will be called as scale factor.
The linear things grow linearly like length, height etc.
The quantities which are squares or multiple of linear things twice grow by square of scale factor. Thus, we need to multiply or divide by k² to get each other corresponding quantity from their similar figures' quantities.
So area of first figure = k² × area of second figure
Similarly,
Volume of first figure = k³ × volume of second figure.
It is because we will need to multiply 3 linear quantities to get volume, which results in k getting multiplied 3 times, thus, cubed.
We are given that;
Volume of material= 1000 cm³
Volume of prism= 8.7 cm³
Now,
Find the volume of the first prism using the formula: V = (1/2)bhℓ1, where b is the base, h is the height of the triangle, and ℓ is the length of the prism. Plug in the given values: V = (1/2)(8.7)(8.7)(10) = 378.45 cm³
Find the volume of the second prism using the same formula, but multiply each dimension by 5 since it is a dilation with a scale factor of 5: V = (1/2)(5b)(5h)(5ℓ) = (1/2)(43.5)(43.5)(50) = 46593.75 cm³
Subtract the volume of material he has from the volume of material he needs for both prisms: 1000 - (378.45 + 46593.75) = -45972.2 cm³
Since he needs more material than he has, he needs to get more material with a volume equal to | -45972.2 | cm³ or 45972.2 cm³.
Therefore, by dilation the answer will be 87.5
