la cancha de futbol del colegio es de forma rectangular, pedro es el cargado de colocar un lazo alrededor para que nadie entre ala cancha si el ladao largo mide 100 mertros y el lado mas corto mide 64 metros ¿ cuanto debe medir el lazo
Answer:
328 metros
Step-by-step explanation:
Aquí, estamos interesados en colocar un bucle alrededor de un campo de fútbol de la escuela de manera que sea imposible que alguien pueda acceder al campo.
Matemáticamente, la longitud de este bucle sería igual al perímetro del campo.
El perímetro del campo rectangular se puede calcular usando la fórmula; 2 (L + B)
En este caso tenemos; P = 2 (100 + 64)
P = 2 (164)
P = 328 metros La longitud del bucle es de 328 metros.

which steps should be used to compare the fraction 2/9 and 5/6
Answer:
last one
Step-by-step explanation:
[tex]\frac{2}{9} *\frac{2}{2 }= \frac{4}{18}[/tex] [tex]\frac{5}{6} *\frac{3}{3} = \frac{15}{18}[/tex]after multiplying the fractions by 2/2 and 3/3 we get a common denominator wich allows us to compare the fractions

It is D
Step-by-step explanation:
Investigate the range of each parent function below over the interval o
ranges from least to greatest.
Identity function, reciprocal function, quadratic function, cubic function, square root function
Answer:
Here we have the domain:
D = 0 < x < 1
And we want to find the range in that domain for:
1) y = f(x) = x
First, if the function is only increasing in the domain (like in this case) the minimum value in the range will match with the minimum in the domain (and the same for the maximums)
f(0) = 0 is the minimum in the range.
f(1) = 1 is the maximum in the range.
The range is:
0 < y < 1.
2) y = f(x) = 1/x.
In this case the function is strictly decreasing in the domain, then the minimum in the domain coincides with the maximum in the range, and the maximum in the domain coincides with the minimum in the range.
f(0) = 1/0 ---> ∞
f(1) = 1/1
Then the range is:
1 < x.
Notice that we do not have an upper bound.
3) y = f(x) = x^2
This function is strictly increasing, then:
f(0) = 0^2 = 0
f(1) = 1^2 = 1
the range is:
0 < y < 1
4) y = f(x) = x^3
This function is strictly increasing in the interval, then:
f(0) = 0^3 = 0
f(1) = 1^3 = 1
the range is:
0 < y < 1.
5) y = f(x) = √x
This function is well defined in the positive reals, and is strictly increasing in our domain, then:
f(0) = √0 = 0
f(1) = √1 =1
The range is:
0 < y < 1

What is the measure of the smallest angle in the right triangle below?
(2x)
(x + 6)°
28°
56°
34°
12°
Answer:
34°
Step-by-step explanation:
If we assume that the acute angles in the triangle are 2x and (x+6), then we have ...
2x +(x +6) = 90
3x +6 = 90 . . . . . . simplify
x + 2 = 30 . . . . . . . divide by 3
x = 28 . . . . . . . . . . subtract 2
Then the angles are ...
2x = 2(28) = 56
x+6 = 28+6 = 34
The smallest angle is 34°.
What will be the first step in answering this equation 9z+3=3z+15 ?
Answer:
Subtract 3z from each side
Step-by-step explanation:
9z+3=3z+15
Subtract 3z from each side
9z-3z+3=3z-3z+15
6z +3 = 15
Subtract 3 from each side
6z+3-3 = 15-3
6z = 12
Divide by 6
6z/6 = 12/6
z=2

4(5n -7) =10+2 i need step by step explanation i dont get it
Answer:
n=2
Step-by-step explanation:
4(5n-7)=10+2
1) First, distribute (multiply out 4)
20n-28=10+2
2) Combine like terms (add 10 and 2)
20n-28=12
3) Isolate the variable (Add 28 to 12)
20n=40
4) Isolate the variable (Divide by 20)
n=2
4x+57=−133 what is x
4x + 57 = -133
Subtract 57 from both sides.
4x = -190
Divide each side by 4
x = -47.5
answer
-47.5
steps
-133 - 57 = -190
-190 divided by 4 = -47.5

f(x)=2x -7, What is x when f(x)=-15?
Answer:
x = -4
Step-by-step explanation:
Plug in -15 into the equation:
f(x) = 2x - 7
-15 = 2x - 7
Solve for x:
-15 = 2x - 7
-8 = 2x
-4 = x
Solve for x: -2(x + 3) = -2(x + 1) - 4. (1 point)

Step-by-step explanation:
[tex]-2 ( x + 3) = -2 (x + 1) -4 \\-2x + 3 = -2x -2 -4\\-2x + 3 = -2x - 6[/tex]
add [tex]2x[/tex] to both sides
[tex]-2x + 3 + 2x = -2x - 6 + 2x \\3 = -6[/tex]
That's impossible
so the equation no solution
Answer:
All real numbers ( -∞ ,∞)
Step-by-step explanation:
Simplify [tex]-2(x+3)[/tex]
Apply the distributive property.
[tex]-2x-6=-2(x+1)-4[/tex]
Simplify
[tex]-2(x+1)-4[/tex]
[tex]-2x-6=-2x -6[/tex]
Move all terms containing x to the left side of the equation.
Add 2 x to both sides of the equation.
[tex]-2x-6+2x=0[/tex]
Combine the opposite terms in
[tex]-2x-6+2x[/tex]
add [tex]-2x[/tex] and [tex]2x[/tex]
[tex]0-6= -6[/tex]
[tex]-6= -6[/tex]
Since [tex]-6= -6[/tex] , the equation will always be true for any value of x . All real numbers
The result can be shown in multiple forms.

Answer:
D. The parabola is translated down 2 units.
Step-by-step explanation:
Comparing the two functions f(x), we see that the second one has a constant of 1 where the first one has a constant of 3. That means every value produced by the second function will be 2 units less than the value produced by the first function.
D. The parabola is translated down 2 units.

A plumber has 8 9/10 feet of rubber tubing to make 2 rubber pipes. He will use3 1/12 feet of tubing to make each pipe. The plumber says he will have about 3 feet of rubber tubing after he makes the pipes. Is his statement reasonable?
Answer:the answer is D
Step-by-step explanation:
This is reasonable because feet can be rounded to 9 feet and feet can be rounded to 3 feet. Since 9 - 2(3) = 3, the plumber will have about 3 feet of rubber tubing left. its true make sure you read the answer to make sure bc they can mix them up LOL
Solve for Y: when X = 6 y= 2x +1
Answer:
y=13
Step-by-step explanation:

=12+1
=13
Answer:
y=13
Step-by-step explanation:
by replacing x in the equation with 6 the equation becomes y=2(6)+1 this is just a simple equation that you use to get the answer. 2×6 is 12 and 12+1=13 so y=13.
