Gente pelo amor de Deus, qual é a responsta dessa questão: "Sendo a área de um retângulo fixado em 36cm². Observa-se na tabela a seguir, algumas possibilidades de medidas para o comprimento e sua respectiva largura.
Comprimento(c) | Largura (l)
18 | 2
12 | 3
9 | 4
6 | 6
Têm-se a que, neste caso, a sentença algébrica que relaciona o comprimento (c), em centímetros, com a largura (I) é:
A) c = 36/l
B) c = 45 + 15l
C) 36 = 2c + 2I
D) I = 36 - c
Answer:
A) c = 36/l
Step-by-step explanation:
A fórmula para a área de um retângulo é dada como Comprimento × Largura ou Comprimento × Respiração
A área do retângulo acima é fornecida como 36cm²
= 36cm² = Comprimento × Largura
36cm² = c × l
Portanto, a sentença algébrica que relaciona o comprimento (c), em correspondência, com a largura (I) é
c = 36 / l
Portanto, a resposta correta = opção A)

Mr X went shopping with a certain amount of money. He spent Rs. 10(¼) on buying a pen and Rs. 25(¾) in food. He then gave the remaining Rs. 16(½) to his friend. Calculate how much money he initially had.
Answer:
Rs. 52[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given parameters:
Amount spent on buying a food = Rs. 25.75
Amount spend on buying pen = Rs. 10.25
Amount given out to friend = Rs. 16.5
Unknown:
The total money he initially had = ?
Solution:
The total money he initially had :
= amount spent on food + amount spent on pen + amount given to friend
= Rs. 25.75 + Rs. 10.25 + Rs. 16.5
= Rs. 52.5 or Rs. 52[tex]\frac{1}{2}[/tex]

Find the value of x.
Answer: 12.65
Step-by-step explanation:
Ive never solved a problem like this, but this is how I would solve it. You first want to find the height of the triangle by using the Pythagorean theorem. Solve for the height by using the left triangle.
[tex](4\sqrt{2} )^2=4^2+b^2\\32=16+b^2\\16=b^2\\b=4[/tex]
b is the height, the dotted line, of both triangles. Now do the Pythagorean theorem on the right triangle to find the value of x
[tex]12^2+4^2=x^2\\144+16=x^2\\160=x^2\\x=\sqrt{160} \\x=12.649=12.65[/tex]

What’s the answer xx
Step-by-step explanation:
Hey there!
Given;
ABC is a Right angled triangle.
Taking angle "A" as reference angle, we get;
Perpendicular (p) = BC
hypotenuse (h) = 13cm
Base(b) = 8cm
We know;
[tex] {h}^{2} = {p}^{2} + {b}^{2} [/tex]
[tex]or; \: p(BC) = \sqrt{ {h}^{2} - {b}^{2} } [/tex]
[tex] BC = \sqrt{ {13}^{2} - {8}^{2} } [/tex]
[tex] BC = \sqrt{169 - 64} [/tex]
[tex] BC = \sqrt{105} [/tex]
[tex] BC = 10.246[/tex]
Therefore, BC = 10.246cm.

Step-by-step explanation:
You need to use the pythagorean theorem. a^2 +b^2=c^2. Label the sides with a, b, and c. The longest side is c, but it does not matter for the other two sides.
Answer:
y = 12
Step-by-step explanation:
[tex]c^{2}[/tex] = [tex]a^{2}[/tex] - [tex]b^{2}[/tex]
[tex]c^{2}[/tex] = [tex]35^{2}[/tex] - [tex]37^{2}[/tex]
[tex]35^{2}[/tex] = 1,225
[tex]37^{2}[/tex] = 1,369
1,369 - 1,225 = 144
[tex]\sqrt{144}[/tex] = [tex]c^{2}[/tex]
[tex]\sqrt{144}[/tex] = 12
A high-pressure air mass is most likely to bring A) lower humidity. B) higher humidity. lower temperatures. D) higher temperatures.
Answer:
b
Step-by-step explanation:
i think its b but im not 100% sure
A high-pressure air mass is most likely to bring lower humidity. the correct answer would be an option (A).
What is humidity?In general, humidity is a measurement of the amount of water vapor in the air. Meteorologists often divide water vapor in the atmosphere into two categories: absolute humidity and relative humidity. Dew point is an exact statistic that helps us comprehend how damp and humid it feels outside.
A high-pressure air mass typically brings lower humidity because high-pressure air masses are associated with clear and dry weather conditions.
The sinking motion of air in a high-pressure system compresses and warms the air, causing the relative humidity to decrease as moisture is squeezed out of the air.
This results in lower humidity levels compared to a low-pressure system, which brings moist air from the surrounding areas.
Hence, the correct answer would be option (A) lower humidity.

which of the tables represent a function?
PLEASE BE QUIIICCCKKK
Answer:
I think its C or A
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
A function can never have a 'x' with two values.
If you say f(x) = a, then there is only one number 'a' which satisfy. If however, you say f(x) = a & f(x) = b, then it's not a function, since there are two values of f(x).
Following this,
A: x = 3 has two f(x) = 2 & 1, so it's not a function
Similarly you can check for all.
There is only one table which x has a unique value.
Correct B
Note that, f(x) = a & f(x) = b, doesnt represent a function. If it is, then a = b is must.
Also, a function is possible only when it satisfies this. But
f(x) = a, f(y) = a, f(z) = a is possible.
On a flight from New York to London, an airplane travels at a constant speed. An equation relating the distance traveled in miles, d, to the number of hours flying, t, is LaTeX: t=\frac{1}{500}dt=1500d. How long will it take the airplane to travel 800 miles?
Answer:
1.6hours
Step-by-step explanation:
We know that Speed= distance/ time
But from the question, An equation relating the distance traveled in miles d to the number of hours flying t is t= 1/500d.
And the distance is given as 800 miles
Then, what we need is to substitute the given Distance into the equation of time.
t= 1/500d. Where d= 800 miles
t= (1/500) × 800 miles
t= 800 miles/500
t= 1.6hours
Hence, it will take the airplane to travel 800 miles , 1.6hours
