Answer:
The square root of (17/25) is the same as the square root of 17 divided by the square root of 25. You can divide the fraction inside the radical before or after you calculate the square root. The result will be the same.
Here we first calculate the square root of the numerator and the square root of the denominator separately, and then we divide the two:
√17 √25 ≈ 4.1231 5 ≈ 0.8246
Alternatively, we first divide 17 by 25 and then do the square root of the quotient:
√17/25 = √0.68 ≈ 0.8246
0

A rare delicate plant will only produce flowers from 10% of the seeds to see any flowers, the situation is going to be stimulated. Which of these options is the best stimulation?
Answer:
Another plant can be genetically modified to produce flowers 10% of the time. Plant 30 groups of 5 seeds each and wait 6 months for the plants to grow and count the fraction of groups that produce flowers.
Roll a standard number cube 5 times. Each time a 6 appears, it represents a plant producing flowers. Repeat this process 30 times and count the fraction of times at least one number 6 appears.
Have a computer produce 5 random digits (0 through 9). If a 9 appears in the list of digits, it represents a plant producing flowers. Repeat this process 300 times and count the fraction of times at least one number 9 appears.
Create a spinner with 10 equal sections and mark one of them “flowers.” Spin the spinner 5 times to represent the 5 seeds. Repeat this process 30 times and count the fraction of times that at least 1 “flower” was spun.

A salesman earns 20% commission on all the merchandise that he sells. Last month he sold $900 worth of merchandise. How much commission (in dollars) did he earn last month?
Answer: $180
Step-by-step explanation:
Given
Salesman earns 20% commission on merchandise he sells
Last month sales by him are $900
So, his commission out of $900
[tex]\Rightarrow 20\%\ \text{of}\ 900=0.2\times 900\\\Rightarrow \$180[/tex]
So, he grabbed $180 dollar as commissions

Determine whether the quadratic function show below has a minimum or maximum then determine the minimum or maximum value of the function
f(x) = 3x^2 - 18x + 29
Answer:
The quadratic has a minimum value.
The minimum value is at (3, 2).
Step-by-step explanation:
We are given the quadratic function:
[tex]f(x)=3x^2-18x+29[/tex]
First, since the leading coefficient is positive, this quadratic function will be concave up.
Hence, we will have a minimum value.
The minimum or maximum value is the vertex of the quadratic. The vertex is given by:
[tex]\displaystyle \Big(-\frac{b}{2a},f\Big(-\frac{b}{2a}\Big)\Big)[/tex]
In this case, a = 3, b = -18, and c = 29. Thus, the x-coordinate of the vertex is:
[tex]\displaystyle x=-\frac{-18}{2(3)}=\frac{18}{6}=3[/tex]
And the minimum value is:
[tex]f(3)=3(3)^2-18(3)+29=2[/tex]

Answer:
[tex]Surface\ area = 6728.3125(pi)\\\\Surface\ area = 21137.6171211[/tex]
Step-by-step explanation:
The lateral surface area of an object is the surface area of the subject excluding the base and the top of the 3-dimensional figure. The surface area of the object is the 2-dimensional space of an object, in essence, if one was going to wrap the object, the amount of material they would need to cover the object. To find the lateral surface area of a cylinder, one must find the circumference of the circle at the top of the cylinder, and then multiply it by the height of the cylinder. The circumference of a circle is the distance around it, the perimeter.
The formula one would use is,
[tex]A_s = (pi)(r^2)(h)[/tex]
Were (pi) represent the value (3.1415...), (r) represent the radius of the base, that is the distance from the center point of the circle on the base, to the outside distance of the circle. The radius of a circle is always half of the diameter. (h) represents the height of the figure.
[tex]A_s = (pi)(r^2)(h)\\\\= (pi)((\frac{3.5}{2})^2))(13)\\\\= (pi)(1.75)^2(13)\\\\= (517.5625)(13)(pi)\\\\=(6728.3125)(pi)\\\\= ~21137.6171211[/tex]

A cell phone company offers its customers a monthly plan that cost $55 per month plus 0.08 for each minute used
Answer:
The equation is y= 0.08 x+55
Step-by-step explanation:
Let's use total cost y= Variable cost + fixed cost.
Here fixed cost =$55
And variable cost for each minute =0.08
That's variable cost for x minutes =0.08
So, total cost y=0.08 x+55
Determine whether the following equation represents a direct variation If it does, find the constant of variation
2x + 3y = 0
Given:
The equation is
[tex]2x+3y=0[/tex]
To find:
Whether the equation represents a direct variation. If it does, find the constant of variation.
Solution:
The general equation of direct variation is
[tex]y=kx[/tex] ...(i)
Where, k is the constant of variation.
The equation of direct variation is always true for (0,0).
The given equation is
[tex]2x+3y=0[/tex]
It can be written as
[tex]3y=-2x[/tex]
[tex]y=-\dfrac{2}{3}x[/tex] ...(ii)
For x=0,
[tex]y=-\dfrac{2}{3}(0)[/tex]
[tex]y=0[/tex]
The given equation is true for (0,0). So, it represents a direct variation.
On comparing (i) and (ii), we get
[tex]k=-\dfrac{2}{3}[/tex]
Therefore, the constant of variation is [tex]-\dfrac{2}{3}[/tex].

Which system of linear equations represents the lines graphed below?
Answer:
B
Step-by-step explanation:
I took the test and got it right
Answer:
Option D is the correct answer.
Step-by-step explanation:
Both the lines are intersecting each other at point (-6, 4)
So, x = - 6 & y = 4
Let us plug x = - 6 in the equation [tex] y =-\frac{1}{3} x + 2[/tex]
We find that:
[tex] y =-\frac{1}{3} (-6) + 2[/tex]
[tex] y =-(-2) + 2[/tex]
[tex] y = 2 + 2[/tex]
[tex] y = 4[/tex]
So, when x = - 6, the value of y is 4.
Since, second equation of option D is invisible, hence I can't provide any explanation for the same.
A group of friends go out for lunch. If they order 2 hot dogs and 4 cheeseburgers, the bill will
be $23.50. If they order 5 hot dogs and only 1 cheeseburger, the bill will be $18.25. What is
the cost of a hot dog?
Answer:
$2.75 = cost of a hot dog
$4.50 = cost of a cheeseburger
Step-by-step explanation:
Let x = cost of a hot dog
y = cost of a cheeseburger
(1) 2x + 4y = 23.5 (2) 5x + y = 18.25
y = 18.25 - 5x
2x +4(18.25 - 5x) = 23.5
2x + 73 - 20x = 23.5
-18x + 73 = 23.5
-18x = -49.5
x = 2.75 y = 18.25 - 5(2.75)
y = 18.25 - 13.75
y = 4.50
$2.75 = cost of a hot dog
$4.50 = cost of a cheeseburger

A sculpture is in the shape of a cylinder. The sculpture has a diameter of 10 feet and a height of 21 feet. Which measurement is closest to the total surface area of the sculpture in square feet?
Answer:did u get the answer?
Step-by-step explanation:sorry
The measurement of total surface area of the sculpture in square feet is 814 square feet.
What is the surface area of a cylinder?The surface area of a cylinder can be calculated by adding the area of its lateral surface to the sum of the areas of its two circular ends. The formula for lateral surface area is given by: 2πrh
where r is the radius of the circular base and h is the height of the cylinder.
Since the diameter of the cylinder is 10 feet, the radius is 10/2 = 5 feet.
So, the lateral surface area of the cylinder = 2 × π × 5 × 21 = 210π square feet.
The area of each circular end is given by πr². Since the radius is 5 feet, the area of each circular end is π × 5² = 25π square feet.
Therefore, the total surface area of the cylinder is 210π + 2 × 25π = 260π square feet.
The value of π is approximately 3.14, so the surface area of the cylinder is approximately 260 × 3.14 = 816.4 square feet.
So, the closest measurement of the total surface area of the sculpture in square feet is 816 square feet.
