Um terreno retangular possui o comprimento cinco vezes maior que a largura. Sabendo que o perímetro desse terreno é igual a 180 metros, a largura e o comprimento medem, respectivamente: * 30 m e 150 m 75 m e 15 m 15 m e 75 m 150 m e 30 m 90 m e 90 m
Responder:
15 m e 75 m
Explicação passo a passo:
Deixar :
Largura = x
Comprimento = 5x
Perímetro = 180
Já o terreno tem uma forma retangular; usamos a relação;
Perímetro = 2 (comprimento + largura)
180 = 2 (5x + x)
180 = 2 (6x)
180 = 12x
180/12 = x
15 = x
Largura = x = 15 metros
Comprimento = 5x = 15 * 5 = 75 metros
Medida de largura e comprimento, respectivamente:
15 m e 75 m

• He uses his protractor to draw a angle on one end of the line
segment.
ANSWER BOTH QUESTIONS ILL GIVE BRANLIEST AND LOTS OF POINTS .
Noah could draw a triangle with side lengths 4 cm, 6 cm, and approximately 10.39 cm, with angles of 30°, 30°, and 120°.
How to solveYes, there is a different triangle Noah could draw. Since Noah has only drawn one side and one angle, he can create two different triangles using the Angle-Side-Side (A S. S) ambiguity
To find the other possible triangle, we need to calculate the angle opposite the 6 cm side. In this case, the given angle is 30°. Using the sine rule, we can find the sine of the opposite angle (let's call it θ):
sin(θ) / 6 = sin(30°) / 4
sin(θ) = (6 * sin(30°)) / 4
sin(θ) ≈ 0.5
θ ≈ 30°
Since the sum of angles in a triangle is 180°, the other angle in the triangle is:
180° - 30° - 30° = 120°
Now, we can use the sine rule again to find the length of the side opposite this new angle:
x / sin(120°) = 6 / sin(30°)
x ≈ 6 * sin(120°) / sin(30°)
x ≈ 10.39 cm
Therefore, Noah could draw a triangle with side lengths 4 cm, 6 cm, and approximately 10.39 cm, with angles of 30°, 30°, and 120°.

Two researchers are studying the decline of orangutan populations. In one study, a population of 784 orangutans is expected to decrease at a rate of 25 orangutans per year. In a second study, the population of a group of 817 orangutans is expected to decrease at a rate of 36 per year. After how many years will the two populations be the same?
The two populations will be the same after
years.
Answer:
3 years
Step-by-step explanation:
Let y = number of orangutans, and let x = number of years.
For each study, the population, y, after x years is:
First study:
y = 784 - 25x
Second study:
y = 817 - 36x
We set the populations equal and solve for x, the number of years.
784 - 25x = 817 - 36x
Add 36x to both sides. Subtract 784 from both sides.
11x = 33
Divide both sides by 11.
x = 3
Answer: 3 years

Step-by-step explanation:
You are planning to work in the summer (13 weeks). You
are deciding between working as a lifeguard or a camp counselor. The lifeguard job
pays $12 per hour and a $500 signing bonus. The camp counselor job pays $15 per
hour with no signing bonus.
Answer:
(a) Equations for both
[tex]y = 500 + 12x[/tex] --- lifeguard
[tex]y = 15x[/tex] --- camp counselor
(b) Total pay for 5 days
Lifeguard pays $800
Camp counselor pays $375
(c) Which pays more
Lifeguard job pays more
Step-by-step explanation:
Let
[tex]x \to hours[/tex]
[tex]y \to total\ pay[/tex]
Given
Lifeguard job
[tex]Signing\ bonus = \$500[/tex]
[tex]Rate = \$12/hr[/tex]
Camp counselor job
[tex]Signing\ bonus =\$0[/tex]
[tex]Rate = \$15/hr[/tex]
Solving (a): The equation for both
The total pay for each job is calculated as:
Total Pay = Signing Bonus + Rate * Hours
So, we have:
Lifeguard
[tex]y = 500 + 12*x[/tex]
[tex]y = 500 + 12x[/tex]
Camp counselor
[tex]y = 0 + 15 * x[/tex]
[tex]y = 15x[/tex]
Solving (b): Total pay for 5 days
First, we calculate the total hours worked in 5 days
[tex]x = 5hrs/day * 5days[/tex]
[tex]x = 25hrs[/tex]
So, the pay for each is:
[tex]y = 500 + 12x[/tex]
[tex]y =500 + 12*25[/tex]
[tex]y =800[/tex] --- Lifeguard
[tex]y = 15x[/tex]
[tex]y = 15 * 25[/tex]
[tex]y = 375[/tex] --- camp counselor
Solving (c): Which job pays more
By comparing the solution in (b)
[tex]800 > 375[/tex]
Hence, lifeguard job pays more

Let h(x) = x*2 + kw - 8. If h(-1) = -5, what is the value of h(4)?
Help
Answer:
h(4) = 0
Step-by-step explanation:
Hoping its ' kx '
[tex]h(x) = x^2 + kx -8 \\\\h(-1) = (-1)^2 + k(-1) - 8\\\\-5 = 1 - k -8\\\\-5 = -k -7\\\\-5 + 7 = -k\\\\2 = -k\\-2 = k[/tex]
Now we have k = -2. We will find h(4).
[tex]h(4) = (4)^2 + (-2)(4) - 8 = 16 -8 - 8 = 0[/tex]
Answer:
h(4) = 0
Step-by-step explanation:
GIVEN :-
A quadratic function h(x) = x² + kx - 8h(-1) = -5TO FIND :-
Value of h(4)SOLUTION :-
To find the value of h(4) , you need to find 'k' first by using the given facts.
[tex]h(-1) = (-1)^2 + k(-1) - 8 = -5[/tex]
[tex]=> 1 - k - 8 = -5[/tex]
[tex]=> -k - 7 = -5[/tex]
Add both the sides by 7.[tex]=> -k - 7 + 7 = -5 + 7[/tex]
[tex]=> -k = 2[/tex]
Multiply both the sides by -1.[tex]=> -k(-1) = 2(-1)[/tex]
[tex]=> k = -2[/tex]
Putting the value of k,
[tex]h(4) = (4)^2 + (-2)(4) - 8[/tex]
[tex]= 16 - 8 - 8[/tex]
[tex]= 16 - 16[/tex]
[tex]= 0[/tex]
A box contains 3 red marbles, 5 white marbles and 7 blue marbles, 2 balls are drawn at random. Calculate probability? a, There is 1 red ball out of the 2 balls drawn b, There is at least 1 red ball out of 2 balls drawn
Answer:
a) 0.3429 = 34.29% probability there is 1 red ball out of the 2 balls drawn.
b) 0.3715 = 37.15% probability that there is at least 1 red ball out of 2 balls drawn
Step-by-step explanation:
The balls are drawn without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x successes is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of successes.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
3 + 5 + 7 = 15 balls, which means that [tex]N = 15[/tex]
3 red, which means that [tex]k = 3[/tex]
2 drawn, which means that [tex]n = 2[/tex]
a) Probability there is 1 red ball out of the 2 balls drawn
This is [tex]P(X = 1)[/tex]
So
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 1) = h(1,15,2,3) = \frac{C_{3,1}*C_{12,1}}{C_{15,2}} = 0.3429[/tex]
0.3429 = 34.29% probability there is 1 red ball out of the 2 balls drawn.
b) Probability there is at least 1 red ball out of 2 balls drawn
This is:
[tex]P(X \geq 1) = P(X = 1) + P(X = 2)[/tex]
So
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 1) = h(1,15,2,3) = \frac{C_{3,1}*C_{12,1}}{C_{15,2}} = 0.3429[/tex]
[tex]P(X = 2) = h(2,15,2,3) = \frac{C_{3,2}*C_{12,0}}{C_{15,2}} = 0.0286[/tex]
[tex]P(X \geq 1) = P(X = 1) + P(X = 2) = 0.3429 + 0.0286 = 0.3715[/tex]
0.3715 = 37.15% probability that there is at least 1 red ball out of 2 balls drawn
