Work out the circumference and area of glass needed for the top of a display cabinet which has a diameter of 1.8m
Answer:The area of a circle with radius 0.2865 is 0.2579
Step-by-step explanation: Area of a circle in terms of radius:
Area = π·r2 = 3.14·0.292 = 0.26 square meters(*)
Area of a circle in terms of diameter:
Area = π·(d

)2 = 3.14·(0.57

The circumference of circle is 5.652m.
What is Circumference of circle?The circumference of a circle is its boundary or the length of the complete arc of a circle.
The formula for the circumference of a circle is expressed using the radius 'r' of the circle and the value of 'pi'. It is expressed as, Circumference of a circle formula = 2πr. While using this circumference formula, if we do not have the value of the radius, we can find it using the diameter.
For example:
If the radius of the circle is 25 units, find the circumference of the circle. (Take π = 3.14)
Solution: Given, radius = 25 units
Let us write the circumference formula and then we will substitute the value of r (radius) in it.
Circumference of circle formula = 2πr
C = 2 × π × 25
C = 2 × 3.14 × 25 = 157 units
Therefore, the circumference of a circle is 157 units.
Given:
diameter= 1.8 m
radius= 0.9m
Now, Circumference of circle
=2πr
= 2* 3.14 * 0.9
= 5.652 m
Hence, the circumference of circle is 5.652m.

Use the quadratic model y = -4x^2 - 3x + 4 to predict y if x equals 5.
A. -89
B. -111
C. -411
D. -51
Answer:
B. -111
Step-by-step explanation:
y = -4x^2 - 3x + 4
x = 5
y = -4(5)^2 - 3(5) + 4
y = -4(25) - 15 + 4
y = -100 - 15 + 4
y = -111
...............................................................................................................................................
Please, write -4x^2 (not 04x2).
Then the quadratic model is y = -4x^2 - 3x + 4.
Now substitute 5 for x: y(5) = -4 (5)^2 - 3(5) + 4
Simplifying, y(5) = -4(25) - 15 + 4 = -100 - 11 = -111.

Answer:
AE = CE = 12 in
Step-by-step explanation:
Angles BDF and BCF are base angles of their respective isosceles triangles. That means the a.pex angle of each, DBF and ABC respectively is ...
180° -2×30° = 120°
In your diagram, BC is 120° from the -x axis, so is 60° from the +x axis. It bisects the angle DBE. Similarly, BE is 120° from the +x axis, so is 60° from the -x axis. It bisects angle ABC. In an isosceles triangle, the a.pex angle bisector is an altitude and is the perpendicular bisector of the base segment. Any point on that line is equidistant from the base vertices.
Point C lies on the perpendicular bisector of DE, so CD ≅ CE = 12 in.
Point E lies on the perpendicular bisector of AC, so EC ≅ EA = 12 in.
The measurements of interest are ...
AE = CE = 12 in.
_____
Additional comment
Point F serves no purpose except to confuse the issue. Each of the angles that reference point F could be described equally well using a different point:
∠BDF = ∠BDE
∠BCF = ∠BCA
This makes it more obvious that the triangles of interest are similar.
Answer:
12
12
Step-by-step explanation:
see the below figure
i got that both triangles are similar
we get that in triangle ABC angle BCF is 30
so angle A is also 30 (isosceles)
so the remaining angle ABC is 120
and angle CBD becomes 180 - 120 = 60
now in triangle BDE angle BDF is 30
so angle BED is also 30
now angle EBC becomes 120 - angle CBD = 120 - 60
and got angles ABE EBC CBD as 60 each
so three 60 degree angles are formed at vertex B as shown in the figure
tw0 30 30 120 degree triangles are similar
BC becomes perpendicular angular bisector of ED
C is a point on that line which is at equal distance from the base vertices
so CD = CE = 12
here BE is perpendicular bisector of AC
so AE = EC = 12

Combined, there are Asians, Africans, Europeans, and Americans in a village. The number of Asians exceeds the number of Africans and Europeans by . The difference between the number of Europeans and Americans is . If the number of Africans is doubled, their population exceeds the number of Europeans and Americans by . Determine the number of Asians, Africans, Europeans, and Americans in this village
There are 123 Asians, 25 Africans, 21 Europeans and 8 Americans in the village.
To determine the number of Asians, Africans, Europeans, and Americans in the village, the following calculation must be performed:
A.S + A.F + E.U + A.M = 177 A.S = A.F + E.U + 69 E.U - A.M = 13 E.U = A.M + 13 2A.F = E.U + A.M + 29 A.F + E.U + 69 + A.F + E.U + A.M = 177 A.F + A.M + 13 + 69 + A.F + A.M + 13 + A.M = 177 2A.F + 3A.M = 177 - 13 - 13 - 69 E.U + A.M + 29 + 3A.M = 82 A.M + 13 + A.M + 29 + 3A.M = 82 5A.M = 82 - 13 - 29 A.M = 40/5 A.M = 8 E.U = 8 + 13 = 21 A.F = (21 + 29) / 2 = 25 A.S = 177 - 25 - 21 - 8 = 123
Therefore, there are 123 Asians, 25 Africans, 21 Europeans and 8 Americans in the village.

Hello! My name is Galaxy and I will be helping you today, I hope you are having a nice day!
We can solve this in two steps, Comprehension and Solving. I'll go ahead and start with Comprehension.
If you have any questions feel free to ask away!!
Comprehension
We know according to the laws of geometry that all angles in a triangle add up to 180 degrees.
We also know that in an isosceles angle, the base angles are equation to each other.
Now that we know what we need to know, we can setup an equation.
[tex]2x-6+(2x)=180[/tex]
We can do this because first of all, we know that 2x-6 is one of the angles and as per the base angles of an isosceles triangle we know that both base angles are x, therefore we can add 2x to get 180 degrees.
I'll start solving now.
Solving
We can solve this by using the equation we made above and solving it with algebra.
[tex]2x-6+2x=180\\4x-6=180\\4x=186\\x=46.5[/tex]
We know that x is equal to 46.5 degrees. We can check that by inputting it into the equation.
[tex]2(46.5)-6+2(46.5)=180?\\4(46.5)=186?\\46.5=46.5[/tex]
We've proven that our answer is correct by double checking,
Therefore the answer is 46.5!

What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The function is,
⇒ 12x + 6y = 247
Now,
We have;
The domain is, {-4,0,5)
Hence, The range of the function is find as;
Put x = - 4;
⇒ 12x + 6y = 247
⇒ 12 × - 4 + 6y = 247
⇒ - 48 + 6y = 247
⇒ 6y = 247 + 48
⇒ 6y = 295
⇒ y = 49.17
Put x = 0;
⇒ 12x + 6y = 247
⇒ 0 + 6y = 247
⇒ 6y = 247
⇒ y = 41.17
Put x = 5;
⇒ 12x + 6y = 247
⇒ 60 + 6y = 247
⇒ 6y = 247 - 60
⇒ 6y = 187
⇒ y = 31.17
Thus, The range for the relation 12x + 6y= 247 is,
Range = {49.17, 41.17, 31.17}
