Answer:
petunias, snapdragons, then pansy
Step-by-step explanation:
Ok first, lets find the percentage of 18 out of 40: 18/40= 0.45
The 21 out of 50= 21/50= 0.42
Lastly, 12/30= 0.40
And its very simple to put from least to greatest:
0.40, 0.42, 0.45
Hope this helped ;)
The answer is petunias, snapdragons, then pansies.

an equilateral triangle has a side length of 10 units. what is its area?
Answer:
Area of equilateral triangle = 43.3 units^2
Step-by-step explanation:
An equilateral triangle is a triangle in which all three sides of triangle are equal.
So,Length = 10 units
Area of triangle = [tex]\frac{\sqrt{3} }{4}*(side)^2[/tex]
= [tex]\frac{\sqrt{3} }{4}*(10)^2[/tex]
= [tex]\frac{\sqrt{3} }{4}*(100)[/tex]
= [tex]43.3units^2[/tex]
So, Area of equilateral triangle = 43.3 units^2.
The answer is:
The area of the triangle is equal to [tex]A=43.30units^{2}[/tex]
Why?To calculate the area of an equilateral triangle, we need to use the following formula:
[tex]A=\frac{s^{2} *\sqrt{3}}{4}[/tex]
Now, we are given an equilateral triangle, so we know that all of its sides are equal to 10 units.
So, calculating the area we have:
[tex]A=\frac{s^{2} *\sqrt{3} }{4}\\\\A=\frac{(10units)^{2} *\sqrt{3} }{4}\\\\A=\frac{100units^{2} *\sqrt{3} }{4}=43.30units^{2}[/tex]
Have a nice day!
Please help me idk this
Answer:
[tex]\large\boxed{Surface\ Area=63\ cm^2}[/tex]
Step-by-step explanation:
We have
square with sides s = 3cm
four triangles with base b = 3cm and height h = 9cm.
The formula of an area of a square:
[tex]A_\square=s^2[/tex]
The formula of an area of a triangle:
[tex]A_\triangle=\dfrac{bh}{2}[/tex]
Substitute:
[tex]A_\square=3^2=9\ cm^2\\\\A_\triangle=\dfrac{(3)(9)}{2}=\dfrac{27}{2}=13.5\ cm^2[/tex]
The Surface Area:
[tex]S.A.=A_\square+4A_\triangle\\\\S.A.=9+4(13.5)=9+54=63\ cm^2[/tex]

What is the value of b in the equation (y^b)^4=1/y^24?
A.) -20
B.)-6
C)6
D.)20
Answer:
b = 6
Step-by-step explanation:
In (y^b)^4=1/y^24 we can re-write (y^b)^4 as y^(4b) and then equate this result to y^24. Setting the exponents equal to one another, we get 4b = 24, or b = 6.

Simplify 8r+(-4r)+3 and then solve if r=5
Simplify= 4r+3
Because 8r plus -4r which is 4r and then 3 can’t be simplified so u keep it the same
Then the answer if r=5 is 23
Because the equation looks like 4(5)+3
5 times 4 is 20 plus 3 is 23
Final answer:
The expression 8r+(-4r)+3 simplifies to 4r + 3. Substituting r=5 into the simplified expression gives you 4(5) + 3, which equals 23.
Explanation:
To simplify the expression 8r+(-4r)+3, you combine the like terms which are 8r and -4r. They are like terms because they both contain the variable r.
Simplifying the like terms:
8r + (-4r) = 8r - 4r = 4r
So now the expression simplifies to 4r + 3. To solve for r = 5, you substitute the value of r into the simplified expression:
4r + 3 becomes 4(5) + 3,
20 + 3 = 23.
Therefore, when r = 5, the simplified expression evaluates to 23.

What is the range of the function g(x) = 3x2 - 6x + 3 when the domain is defined as the set of integers, x, such that 0<=x<=4? Show all work. I really need help y’all I have and f :(
Answer:
the domain of this function is [0, 27]
Step-by-step explanation:
One way of answering this question would be to make a table of x and y values. Your x-values would be [0, 4] (that is, all x values between 0 and 4, including end points.
x y = 3x² - 6x + 3
0 3
1 0
2 3
4 27
From this table, it appears highly likely that the smallest y value would be 0, at x = 1, and that the largest would be 27 at x = 4. Thus, the domain of this function is [0, 27].

The following set of coordinates represent which figure?(7,10) (4,7) (6,5) (9,8)
Answer: i think a diamond
Step-by-step explanation:
Let's assume these are the vertices in order and calculated the squared lengths of the sides. Let's calculate the vector for each side, which is the difference of the endpoints:
(7,10) - (4,7) = (3, 3)
(4,7) - (6,5) =(-2, 2)
(6,5) - (9,8) = (-3, -3)
(9,8) - (7,10) = (2, -2)
We see the pattern: (3,3) = -(-3,-3) and (-2,2) = -(2,-2)
We have two pairs of opposite vectors so we have a parallelogram.
Let's check the dot product of adjacent sides:
(3,3) . (-2, 2) = 3(-2) + 3(2) = 0
Zero dot product, we have perpendicularity. A parallelogram with one right angle is a

The circumference of a pizza is 81 in. What is the radius?
If the circumference of a pizza is 81 inches, the radius would be 12.89155 inches.
10 in.
6 in.
8 in,
7 in.what is the surface area
Final answer:
The surface area of the rectangular prism is 376 square inches.
Explanation:
To find the surface area of an object, we need to calculate the sum of the areas of all its faces. Given the dimensions 10 in., 6 in., 8 in., and 7 in., we can assume that these are the lengths of the sides of a rectangular prism. The formula to find the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l, w, and h represent the length, width, and height of the prism, respectively.
Using the given values, we can substitute 10 in. for l, 6 in. for w, and 8 in. for h to find the surface area:
Surface Area = 2(10 in.)(6 in.) + 2(10 in.)(8 in.) + 2(6 in.)(8 in.)
Surface Area = 120 in² + 160 in² + 96 in²
Surface Area = 376 in²

7: 9 times 8: 108
Answer:
7. 9 times
8. 108 people
Step-by-step explanation:
7. The probability of winning is 25%
So, if a person plays 36 times, the probability will be:
25% of 36

=> 36 * 0.25
=> 9 times
So, option 3 is correct .
8. Total number of people asked are 300
and
The percentage of people who prefer two-door cars are 36%
So, the number of people who prefer two-door car are:
300 * 36/100
=> 300 * 0.36
=> 108 people
So, option 1 is correct ..

Aunt Gwen is pricing cakes for a baby shower she is throwing. She wants one large cake shaped like a duckling and also some cupcakes in pastel colors. Hillsboro Bakery charges $4 for each cupcake, plus $28 for the large cake. Carson's Sweet Shoppe charges $55 for the large cake and $1 for each cupcake. If Aunt Gwen orders a certain number of cupcakes, the cost will be the same at either bakery. How many cupcakes would that include? What would the total cost be?
If Aunt Gwen orders ___ cupcakes, it will cost $ ___ at either shop.
Answer:
9 cupcakes and 64$
Step-by-step explanation:
try the math
So first, set up an equation for each shop, for the first one you can write 4x+28 (since it is 4 dollars for each cupcake and 28 dollars for the cake) and for the second shop you can write 55+x ( 55 dollars for cake and a dollar for each cupcake.) now you can set the 2 equations equal to each other because they want the number for cupcakes where the price will be equal. So 4x+28=55+x and then solve. I don’t want to completely tell you the answer but if you are stuck, you can tell me and I will gladly help.

given the functiom y=x^4 -8x^2+16. on which intervals is the function increasing
Answer:
[tex]x\in (-2,0)\cup (2,\infty)[/tex]
Step-by-step explanation:
Find the derivative of the function [tex]y=x^4 -8x^2 +16:[/tex]
[tex]y'=4x^3 -8\cdot 2x\\ \\y'=4x^3 -16x[/tex]
The function is increasing when [tex]y'>0,[/tex] so solve the inequality
[tex]4x^3-16x>0\\ \\4x(x^2-4)>0\\ \\4x(x-2)(x+2)>0\\ \\x\in (-2,0)\cup (2,\infty)[/tex]
You can see from the graph that the function increases for [tex]x\in (-2,0)\cup (2,\infty)[/tex]
Final answer:
To determine the intervals where the function y = x⁴ - 8x² + 16 is increasing, calculate the first derivative, find its critical points, and analyze the sign changes. The function is increasing on the intervals (-∞, -2), (0, 2), and (2, ∞).
Explanation:
Intervals Where the Function is Increasing
To determine on which intervals the function y = x⁴ - 8x² + 16 is increasing, we need to analyze the function's first derivative. The first derivative, y', indicates the slope of the tangent to the function at any point. When y' > 0, the function is increasing. Let's find the first derivative of the given function:
Take the derivative of the function y with respect to x: y' = 4x³ - 16x.
Set the derivative equal to zero to find critical points: 4x³ - 16x = 0.
Factor out the common term (4x): 4x(x² - 4) = 4x(x + 2)(x - 2) = 0.
Solve for x to find critical points: x = 0, x = -2, and x = 2.
Analyze the sign of y' around these points to determine where the function is increasing and decreasing.
Through analyzing the signs, you will find that the function is increasing on the intervals (-∞, -2), (0, 2), and (2, ∞).
Note that these intervals are determined by looking at the sign changes of the first derivative around the critical points and selecting the intervals where the derivative is positive.
