a door with width 4.20 m has an arc as shown in diagram .Find: a) radius of the arc B) length of the arc to the nearest cm
Answer:
Ok, we know that the width of the door is 4.20m.
Then, if the arc is at the top of the door, we will have that the diameter of that "half circle" will be equal to the width of the door.
Then the diameter of the arc is 4.20m
And the radius is defined as half of the diameter, so we have:
radius = 4.20m/2 = 2.10m
And we can write this in cm (because the probelm ask for it)
1m = 100cm
then 2.10m = 2.1*100cm = 210cm
Now, we know that the perimeter of a circle is:
P = 2*pi*r
where pi = 3.14
Then the perimeter (or arc) of half a circle will be half of that:
Arc = (2*pi*r)/2 = pi*r
and r = 210cm, pi = 3.14
Arc = 3.14*210cm = 659.4cm
I'm just curious.... How do you divide fraction? THIS IS 15 POINTS..... BTW Do not cheat use your own words! :)
Answer:
To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one.
Step-by-step explanation:

By multiplying it by the reciprocal.

Midori cleans the hamster cage every 7 days, brushes the dog every 9 days, and cleans the frog aquarium
every 6 days. If Midori does all three today, how many days will pass before Midori takes care of all three of
these pets on the same day again?
Answer:
126
Step-by-step explanation:
The least common multiple of 7, 9, and 6 is the product of the unique factors.
7 = prime
9 = 3^2
6 = 3·2
The LCM is 7·3^2·2 = 126
Midori will take care of all three pets again after 126 days.

Write one of the equations needed for the system. (must use variables a and c. do not use the space bar when typing answer)
Answer:
adults 2
children 3
Step-by-step explanation:
x + y = 5
12x + 9y = 51
x = 5 - y
12(5 - y) + 9y = 51
60 - 12y + 9y = 51
-3y + 60 = 51
-3y = 51 - 60
-3y = -9
y = -9/-3
y = 3
x = 5 - y
x = 5 - 3
x = 2

Step-by-step explanation:
We can convert this word problem into an equation by examining what it says.
6 times a number
Since we don't know the value of that number, we can represent it as [tex]x[/tex]. 6 times [tex]x[/tex] will be [tex]6x[/tex]
Greater than has this symbol: [tex]>[/tex]
3 less than 4 times a number. We can break this down. 4 times a number is [tex]4x[/tex]. 3 less than that will be [tex]4x-3[/tex].
Combining that all, we get [tex]6x > 4x-3[/tex]

Para executar um serviço, o trabalhador apoiou na laje de sua casa a escada de 4,3 m de comprimento como mostra o esquema abaixo: A base da escada, apoiada sobre um piso horizontal está afastada 1,8 m da parede. Qual é a altura aproximada da construção?
Responda:
3,91 m
Explicação passo a passo:
Dado o seguinte:
Comprimento da escada = 4,3 m
Distância da base da parede = 1,8m
Altura da parede =?
O problema pode ser resolvido usando Pitágoras:
hipoteno = sqrt (oposto² + adjacente ²)
Hipoteno = comprimento da escada = 4,3
4,3 = sqrt (1,8² + altura²)
Quadrar ambos os lados
4,3² = 1,8² + altura²
4,3² - 1,8² = altura²
18,49 - 3,24 = altura²
15. 25 = altura²
Tire a raiz quadrada de ambos os lados
Sqrt (15,25) = altura
Altura = 3,905
Altura = 3,91 m

Starting with the number 10, build a sequence of 5 numbers
Answer:
10, 11, 13, 16, 20
Step-by-step explanation:
Any 4 numbers can be added to the sequence starting with 10. Perhaps you're supposed to use a rule to choose the numbers. For any 4 numbers you might add to the sequence, a rule can be determined.
The rules we usually use are ones that require a constant difference or a constant ratio. The sequence shown above uses the rule that the difference from the previous value is 1 more than the difference between the previous two values.
The measure of an angle is 12° more than twice the measure of its complement. Write and solve and algebraic equation to find the measure of each angle. I need help!
Answer:
∠64° and ∠26°
Step-by-step explanation:
Complementary angles add up to 90° total (two angles).
Lets give variable values to each angle:
x= 12 more than twice the measure of the complement
y= complement
Write an equation equaling to a total of 90:
[tex]x+y=90[/tex]
Write an algebraic expression for the value of x:
[tex]12+2y[/tex]
Insert the value for x into the equation:
[tex]12+2y+y=90[/tex]
Simplify and solve for y:
[tex]12+3y=90\\\\12-12+3y=90-12\\\\3y=78\\\\\frac{3y}{3}=\frac{78}{3}\\\\ y=26[/tex]
The value of y is 26. Insert this value into the original equation and solve for x:
[tex]x+26=90\\\\x+26-26=90-26\\\\x=64[/tex]
The value of x is 64. So, the complemenatry angles are 64° and 26°.
:Done
From the given measure whose angle is 12° more than twice the measure of its complement.
The measure of the two angles is 64° and 26° respectively.
Complementary angles are angles whose sum is equal to 90°. It is usually composed of two angles complementing themselves. Hence, the term complementary angles.
Mathematically;
Let the first angle be p and the second angle be q∴
p + q = 90° ( complemntary angles)
If one of the angles is 12 more than twice its complement;
i.e.
Let p = 12
SO, the algebraic equation for the value of p is:
12 + 2q = 90
Replacing the value of q to solve the equation, we have:
12 + 2q + q = 90
12 + 3q = 90
3q = 90 - 12
3q = 78
q = 78/3
q = 26°
From p + q = 90° ( complemntary angles)
Replacing the value of q = 26°, we have:
p + 26° = 90°
p = 90° - 26°
p = 64°
In conclusion, the measure of each angle is 64° and 26°.

The perimeter of each polygon created by the coordinates is 15.2 units
How to find the perimeter of each polygon created by the coordinates?The coordinates are given as:
A(-2, 3), B(3, 1), C(-2, -1), D(-3, 1)
Calculate the distance between each point using
d = √(x2 - x1)^2+ (y2 - y1)^2
So, we have:
dAB = √(-2 - 3)^2+ (3 - 1)^2 = 5.4
dBC = √(3 + 2)^2+ (1 + 1)^2 = 5.4
dCD = √(-2 + 3)^2+ (-1 - 1)^2 = 2.2
dDA = √(-3 + 2)^2+ (1 - 3)^2 = 2.2
The perimeter is calculated as:
P = 5.4 + 5.4 + 2.2 + 2.2
Evaluate
P = 15.2
Hence, the perimeter of each polygon created by the coordinates is 15.2 units
