Answer:
about 236.715 ft²
Step-by-step explanation:
area of a circle = πr²
so π7.5² = 176.7145868
area of a rectangle is b × h
so 15 × 4 = 60
60 + 176.7145868 = 236.7145868 ft² ≈ 236.715 ft² (for the nearest thousandths)
Find the ratio of the volume of the triangular prism
to the volume of the cuboid,
Give your answer in its simplest form
고
Answer:
The ratio of the volume of the triangular prism to the volume of the cuboid is [tex]\frac{3}{20}[/tex].
Step-by-step explanation:
Geometrically speaking, the volume of the prism is equal to the product of the area of the base and its height. Then, the volumes of the triangular prism and the cuboid are, respectively:
Triangular prism
[tex]V_{tp} = \frac{1}{2}\times 5\,cm \times 4\,cm \times 9\,cm[/tex]
[tex]V_{tp} = 90\,cm^{3}[/tex]
Cuboid
[tex]V_{c} = 6\,cm\times 5\,cm \times 20\,cm[/tex]
[tex]V_{c} = 600\,cm^{3}[/tex]
Lastly, the ratio of the volume of the triangular prism to the volume of the cuboid is:
[tex]r = \frac{V_{tp}}{V_{c}}[/tex]
[tex]r = \frac{3}{20}[/tex]
The ratio of the volume of the triangular prism to the volume of the cuboid is [tex]\frac{3}{20}[/tex].

Question 4 of 10
Suppose that many large samples are taken from a population, and the
sample proportions center around 0.58. Which of the following is most likely
to be the population parameter?
O A. 0.68
OB. 0.58
O C. 0.78
O D. 0.48
Answer:
A- 0.68
Step-by-step explanation:
0.58 is most likely to be the population parameter, since the sample proportions center around this value.
Option B is the correct answer.
We have,
When many large samples are taken from a population, the sample proportions should converge to the population proportion.
If the sample proportions center around a certain value, that value is likely to be a good estimate of the population proportion.
In this case,
Since the sample proportions center around 0.58, it is likely that the population proportion is also around 0.58.
Therefore,
0.58 is the most likely population parameter.

Which translation vector moves every point of a pre-image 4 units left and 6 units up?
F. (4, -6)
G. (-4, 6)
H. (-6, 4)
J. (6, -4)
Answer:
G(-4,6)
Step-by-step explanation:
Here, we want to write a translation
moving left means we are to subtract the number of units from the original
So we have this as -4
Moving up means we are to add the number of units to the original
So we have this as +6 = + 6 units
So the answer here will be;
(-4,6)
G. (-4, 6).
Given translation is 4 units left and 6 units up.
For left we use negative sign. And for up was use plus sign.
So the translation vector is (-4, 6).

if U=π (r+h),find the value of "r" when U=16 whole 1 upon 2 and h=2
Answer:
r = 3 1/4
Step-by-step explanation:
Here, we want to find the value of r given the values
Firstly, we will write r as the subject of the formula
U = π ( r + h)
U/π = r + h
r = U/π - h
Now substitute;
U = 16 1/2 = 33/2
h = 2
π= 22/7
r = 33/2/22/7 - 2
r = (33/2 * 7/22) - 2
r = 21/4 - 2
r = (21-8)/4
r = 13/4 = 3 1/4

Other root of equation, [tex]\frac{8}{3}[/tex]
Value of ([tex]b[/tex]), [tex]-17[/tex]
Step-by-step explanation:
The given quadratic equation is in standard form. Standard form is the basic format of representing a quadratic equation, a quadratic equation in standard form would use the following format,
[tex]y=ax^2+bx+c[/tex]
To solve this problem, one could use Vieta's theorems. Vieta's theorems state the following, let ([tex]x_1[/tex]) and ([tex]x_2[/tex]) represent the roots of the equation,
[tex](x_1)+(x_2)=-\frac{b}{a}[/tex]
[tex](x_1)(x_2)=\frac{c}{a}[/tex]
Substitute the given values into the equation,
[tex]3+(x_2)=-\frac{b}{3}[/tex]
[tex](3)(x_2)=\frac{24}{3}[/tex]
Simplify,
[tex](3)+(x_2)=-\frac{b}{3}[/tex]
[tex](3)(x_2)=8[/tex]
Inverse operations,
[tex](3)+(x_2)=-\frac{b}{3}[/tex]
[tex]x_2=\frac{8}{3}[/tex]
Substitute in the value of ([tex]x_2[/tex]),
[tex](3)+(\frac{8}{3})=-\frac{b}{3}[/tex]
Simplify, convert to improper fractions and combine like terms,
[tex]\frac{9}{3}+\frac{8}{3}=-\frac{b}{3}[/tex]
[tex]\frac{17}{3}=-\frac{b}{3}[/tex]
Multiply both sides of the equation by ([tex]3[/tex]) to remove the denominator,
[tex]17=-b[/tex]

I don’t know what to do
Answer:
x = 14.4
Step-by-step explanation:
Similar means that the figures are proportional to each other. Because of this, we can form a problem. [tex]\frac{9}{5}[/tex] (the short side lengths) = [tex]\frac{x}{8}[/tex] (the long side lengths). Now we can solve this by cross-multiplying. If we multiply 9 · 8 we get 72, and 5 · x is 5x. 72 = 5x. Now divide both sides by 5. 72 ÷ 5 = 14.4. Therefore, x should be equal to 14.4. Does this make sense?

Meagan and jake both live on the same street that the librarian is on.Megan lives 3.5 blicks north of the library,and jake lives 4.5 blocks south of the library.How many blpcks apart do jake and meagan live.
Answer:
8 blocks
Step-by-step explanation:
As the north direction is upwards and the south direction is downwards the total distance between the two people 's (Megan and Jake) houses will be obtained by adding their distances from the library which is in the middle as shown in the diagram.
Hence total distance between the two houses= 3.5 + 4.5= 8 blocks
Jake and Meagan live 8 blocks apart.

The function f(x) = -5x² + 20x + 55 models the height of a ball x seconds after it is thrown into the air. What is the total time that the ball is in the air?
Answer:
The ball is in the air for about 5.873 seconds.
Step-by-step explanation:
The function:
[tex]f(x)=-5x^2+20x+55[/tex]
Models the height of a ball x seconds after it is thrown in the air.
And we want to find the total time the ball is in the air.
So, we can simply find the time x at which the ball lands. If it lands, its height f above the ground will be 0. Thus:
[tex]0=-5x^2+20x+55[/tex]
We will solve for x. Dividing both sides by -5 yields:
[tex]0=x^2-4x-11[/tex]
The equation is unfactorable, so we can use the quadratic formula:
[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
In this case, a = 1, b = -4, and c = -11. So:
[tex]\displaystyle x=\frac{-(-4)\pm\sqrt{(-4)^2-4(1)(-11)}}{2(1)}[/tex]
Evaluate:
[tex]\displaystyle\begin{aligned} x&=\frac{4\pm\sqrt{16+44}}{2}\\&=\frac{4\pm\sqrt{60}}{2}\\&=\frac{4\pm2\sqrt{15}}{2}\\&=2\pm\sqrt{15}\end{aligned}[/tex]
Approximate:
[tex]x_1=2+\sqrt{15}\approx5.873\text{ or } x_2=2-\sqrt{15}\approx-1.873[/tex]
Since time cannot be negative, our only solution is the first choice.
So, the ball is in the air for about 5.873 seconds.
The radius of a circle is 1 yard. What is the circle's circumference?
r=1 yd
Answer:
6.3 yards
Step-by-step explanation:
mathematically, to get the circumference of the circle, we will have to use the formula for the circumference of a circle
we have this as;
C = 2 * pi * r
r is 1 yard
c = 2 * pi * 1 = 2pi yards = 6.3 yards
