Circular flower bed is 17 m in diameter and has a circular 2 around it is that to meters wide find the area of the sidewalk in square meters use 3.14 for pi
The area of the sidewalk surrounding a circular flower bed with a diameter of 17 meters and a 2-meter wide sidewalk is 119.32 square meters.
The question involves finding the area of a sidewalk that surrounds a circular flower bed. The flower bed has a diameter of 17 meters, and the sidewalk is 2 meters wide. This is a geometry problem that requires us to calculate the area of two circles and then find the difference between them.
Calculate the radius of the inner circle (flower bed): radius = diameter / 2 = 17 m / 2 = 8.5 m.
Calculate the area of the inner circle using the formula A = 3.14 * 8.5 m * 8.5 m = 226.865 m
Calculate the radius of the outer circle (flower bed + sidewalk): radius_outer = radius_inner + width of the sidewalk = 8.5 m + 2 m = 10.5 m.
Calculate the area of the outer circle: A_outer = 3.14 * 10.5 m * 10.5 m = 346.185 m.
Calculate the area of the sidewalk by subtracting the area of the inner circle from the area of the outer circle: Area_sidewalk = A_outer - A_inner
= 346.185 m - 226.865 m
= 119.32 m.
The area of the sidewalk is 119.32 square meters.
Find the radius of the circle whose equation is x^2 + y^2 = 4.
Answer:
Radius of the given circle is r = 2.
Step-by-step explanation:
Given equation of the circle is [tex]x^2 + y^2 = 4[/tex].
Now we need to find the radius of the given circle [tex]x^2 + y^2 = 4[/tex].
To find that let's compare with the formula of the circle with is [tex]x^2 + y^2 = r^2[/tex], where r is the radius.
We get [tex]r^2 = 4[/tex]
take square root of both sides.
[tex]r=2[/tex]
Hence radius of the given circle is r = 2.
ANSWER
The radius is 2
EXPLANATION
The given equation of the circle is
[tex] {x}^{2} + {y}^{2} = 4[/tex]
.This is the same as
[tex]{x}^{2} + {y}^{2} = {2}^{2} [/tex]
We campare to the equation of the circle with center at the origin.
[tex]{x}^{2} + {y}^{2} = {r}^{2} [/tex]
We have
[tex]r = 2[/tex]
.Hence the radius of the circle is 2

The white shape can be transformed into the blue one using
A) a dilation, then a rotation.
B) a rotation, then a reflection.
C) a translation, then a dilation.
D) a reflection, then a translation.
Answer:
B) a rotation, then a reflection
Step-by-step explanation:
you will make a rotatio of 90° about clockwise and reflection about Y- axix
Answer:
B) a rotation, then a reflection.
Step-by-step explanation:
From the given graph, the white shape transformed into blue shape.
If you look at the white shape and the blue shape.
The white shape rotated 45° counter clock wise and reflected over the origin x = y to get the blue figure.
For example, let's take a vertex (2, -1) in the white figure. The corresponding in the blue shape is (-2, 1) which is reflection about the origin.
Therefore the answer is B) a rotation, then a reflection.

Urgent answer plz. Thank u.
[tex]3x \geqslant 23 - 5 \\ 3x \geqslant 18 \\ x \geqslant 6 \\[/tex]
Answer: x≥ 6
Step-by-step explanation:
To solve this inequality
3x - 23 ≥ -5
First, what you need to do is to add 23 to both-side of the inequality, Hence;
3x -23 + 23 ≥ -5 + 23
(-23 + 23 = 0, also -5 + 23 = 18)
3x ≥ 18
To get the value of x, we need to divide both-side of the inequality by 3
3x / 3 ≥ 18/3
(On the left hand side of the equation, the three at the numerator will cancel out that of the denominator, then on the right hand side of the equation, 3 will divide 18 which will give 6)
x ≥ 6

For the right triangle shown, what is the tangent of angle A?
A) 2/3
B) 3/2
C) 3/4
D) 4/3
Answer:
The correct answer is option C 3/4
Step-by-step explanation:
It is given a right angled triangle ABC
To find the value of x
Hypotenuse² = Base² + height²
(x + 2)² = x² + (x + 1)²
x² + 4x + 4 = x² + x² + 2x + 1
x² -2x -3 = 0
We get x = 3 and x = -1
We take positive value x = 3
To find Tan A
Tan A = Opposite side/Adjacent side
= BC/AB = x/(x + 1) = 3/4
Therefore the correct answer is option C. 3/4

Which of the following integers represents the opposite of the opposite of 4?
4
-4
1/4
-1/4
Answer:
[tex]4[/tex]
Step-by-step explanation:
To find the opposite of the opposite, multiply the given number by -1 twice, or just 1 since [tex]-1*-1=1[/tex].
[tex]4*-1*-1=4[/tex] or [tex]4*1=4[/tex]
The opposite of a number is its additive inverse. Therefore, the opposite of the opposite of a given number will always be the original number itself. In this instance, the opposite of the opposite of 4 is 4.
Explanation:The question asks for the opposite of the opposite of a given number. In mathematics, the 'opposite' of a number is its additive inverse. If the original number is positive, its opposite is the same number as a negative. Vice versa, if the original number is negative, its opposite would be positive. For example, the opposite of 4 is -4 and the opposite of -4 is 4.
So let's apply this concept to the given number, which is 4. The opposite of 4 is -4. Now, the opposite of -4 is 4. Hence, the opposite of the opposite of 4 is 4.

Find the first three iterates of the function f(z) = 2z + (3 - 2i) with an initial value of z0 = 4.
Answer:
First Iterate: 11-2i
Second Iterate: 25-6i
Third Iterate: 53-14i
Step-by-step explanation:
Given:
f(z)=2z+(3-2i)
And
z_0=4
For the first iterate we have to put the value of z0 into the function in place of z.
First Iterate:
z_1=f(z_0 )=2z_0+(3-2i)

Ky wants to buy three shirts, which were originally priced 49.96 each. The store will discount the price of the third shirt by 50% and then apply a 7.1% tax to the total cost of all three shirts. Including the tax, what will be the mean cost of each shirt?
49.96 + 49.96 + (49.96x.5)
99.92+24.94=124.86 divide 7.1 and 124.86 which gives you 17.58591549295775 but I’m guessing u round so 17.59 and add that to 124.86which equals 142.45. The total cost is 142.45. But each shirt is 49.96 and the third is 24.94. Don’t forget the dollar sign and have a good day! :)

The rise, r, for each stair is 7 inches.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
From the given figure the length of each stair is 11 inches.
We have to find the rise of each stair.
From the pythagoras theorem we find the value of r.
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.
11²+r²=13²
121+r²=169
r²=169-121
r²=48
Take square root on both sides
r=6.9
r= 7 inches.
Hence, the rise, r, for each stair is 7 inches.

what is the best desert in a math teachers cafe law of sines riddle
is a good desert. people love cake
Final answer:
The question regarding the "best desert in a math teacher's cafe" related to the Law of Sines is likely a pun involving math terms, with "pi" being the intended humorous answer due to its dual significance as a mathematical constant and a type of dessert.
Explanation:
The "best desert in a math teacher's cafe" when mentioned alongside the Law of Sines is likely a playful riddle rather than a straightforward question. The Law of Sines is a mathematical formula used in trigonometry to find missing angles or sides of a triangle, given enough information. It states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is constant for all three sides and angles in the triangle. Therefore, this riddle might be a pun or a play on words related to mathematics or trigonometry terms rather than an actual desert item.
In essence, to solve such riddles, one needs to think creatively, connecting the concept of desert with mathematical terms or principles. A common pun could be "pi," as it sounds like "pie," a type of dessert, and is also an essential constant in mathematics used to calculate the circumference and area of a circle. In the context of a math-themed cafe, "pi" could very well be considered the "best dessert," cleverly linking the world of mathematics with culinary delights in a humorous way.
An office manager reported that he spent $350 on gifts for employees. He said that $240 was spent on clothing with each man receiving a $20 T-shirt and each woman receiving a $40 sweatshirt. He said that $110 was spent on desk accessories with each man receiving a $5 calendar and each woman receiving a $15 stapler. If m equals the number of men and wequals the number of women, the system of equations that represents the expenses is as follows:
m+2w=12
m+3w=22
Answer:
So I assume we are figuring out the number of men and women here, so:
m + 2w = 12
m = 12 - 2w
12 - 2w + 3w = 22
w = 10
m + 2w = 12
m + 2(10) = 12
m + 20 = 12
m = -8
