Answer:
a) La distancia desde el punto del borde más cercano a la posición del escáner es 5 · √5 km
b) El perímetro del área = 84,823 km
El área de la tierra = 572.555 km²
Step-by-step explanation:
a) La distancia desde el punto del borde más cercano a la posición del escáner viene dada por la fórmula de Pitágoras;
r = √a² + b²
Por lo tanto, la distancia = √ (10² + 5²) = √125 = 5 · √5 km
La distancia desde el punto del borde más cercano a la posición del escáner es 5 · √5 km
b) El perímetro está dado por la fórmula para el perímetro de un círculo que es, perímetro, s = π × D
Dónde;
D = El diámetro de la tierra = 27 km.
El perímetro = π × 27 = 84.823 km
El perímetro del área = 84.823 km
El área está dada por la fórmula del área de un círculo = π × D² / 4
El área = π × 27² / 4 = 572.555 km²
El área de la tierra = 572,555 km².

Solve for the variable. 3/4x = -24
Hello!
Answer:
[tex]\huge\boxed{x = -32}[/tex]
3/4x = -24
To isolate the "x" variable, divide both sides by 3/4 (multiply by its reciprocal, or 4/3)
3/4x · 4/3 = -24 · 4/3
x = (-24 · 4) / 3
x = -32.
Answer:
x = -32
Step-by-step explanation:
To solve an equation with a fraction, we multiply by the denominator on both sides of the equation and then solve like a normal algebraic equation.
3/4x = -24 Multiply by 4 on both sides of the equation.
4(3/4)x = -4(24) Distribute.
3x = -96 Divide by 3 on both sides of the equation.
x = -32

Solve x^2+2x=4 for x by completing the square
When completing the square, the goal is to create
a perfect square trinomial on the left side of the equation.
The number used to create one will come from
half the coefficient of the middle term squared.
In this case, that's half of 2 squared or 1 squared, which is 1.
So we add 1 to both sides giving us x² + 2x + 1 = 5.
From here, we set this as a binomial squared.
The first term is an x and the second term will
be half the coefficient of the middle term squared.
So we have (x + 1)² = 5.
Now square root both sides and remember to use plus or minus.
So we have x + 1 = ±√5.
Now subtract 1 form both sides to get x = -1 ± √5.
Volleyballs cost $22.00 each. The Athletic Director has $277.00 in her budget to spend on new volleyballs. There is a $13.00 shipping fee per order. How many volleyballs can the Athletic Director order?
Answer: The Athletic can other 12 volleyballs.
Step-by-step explanation:
If the director has $277 to spend then it means The director can spend at most $277.
Now one volleyball cost $22 and so we could represent the number of volleyballs you can buy by the expression 22x and including the shipping fee,we will extend the expression to 22x + 13 Now since the Director can spend up to $277 or less we can write the whole situation in a form of inequality as,
22x + 13 ≤ 277 Now solve for x to determine the number of volleyballs
-13 -13
22x [tex]\leq[/tex] 264

☆ We know that angles of triangle opposite of its equal sides are also equal
Here the information that we know about the given triangle is
One Angle is 80° Sides are 7 , 7 and 9So the angles opposite to the equal sides will be equal .
→ So one of those equal angle is x so other will also be x .
☆ Interior angle sum property states that sum of interior angles of triangle will be 180°
→ 80° + x + x = 180°
→ 2x = 180°-80°
→ 2x = 100°
→ x = 100/2
→ x = 50° .
So the value of x is 50°.The value of x in the triangle is 50°.
We have,
The given triangle is an isosceles triangle.
This means,
There are two equal sides and the angles opposite to the equal sides are also equal.
Now,
The sum of the three angles in a triangle is 180.
So,
80 + x + x = 180
80 + 2x = 180
2x = 180 - 80
2x = 100
x = 100/2
x = 50°
Now,
We can cross cheked.
80 + 50 + 50
80 + 100
180
True.
Thus,
The value of x in the triangle is 50°.

Train P travels for 330 km at an average speed of x km/h from Kuala Lumpur to Kota Bahru. Train Q travels from Kota Bahru at an average speed of (x-5) km/h and arrives at Kuala Lumpur 30 minutes earlier than train P. Calculate the total time, in hours taken by the 2 trains.
Answer:
Train P : [tex]t_{P} =\frac{330}{55}=6\ \text{hours}[/tex]
Train Q : [tex]t_{Q} =\frac{330}{55}+\frac{1}{2}=6\ \text{hours}\ 30\ \text{minutes}[/tex]
Step-by-step explanation:
The formula to compute the distance traveled by a train is:
[tex]d=s\times t[/tex]
Here,
d = distance traveled
s = speed of the train
t = time taken
From the provided information:
Train P :
d = 330 km
s = x km/h
Then time taken is:
[tex]t=\frac{d}{s}=\frac{330}{x}[/tex]
Train Q :
d = 330 km
s = (x - 5) km/h
[tex]t=\frac{330}{x}+\frac{1}{2}[/tex]
Both the trains traveled the same distance.
[tex]x\times \frac{330}{x}=(x-5)\times [\frac{330}{x}+\frac{1}{2}]\\\\330=\frac{330(x-5)}{x}+\frac{x-5}{2}\\\\330\times 2x=[660(x-5)+x(x-5)]\\\\660x=660x-3300+x^{2}-5x\\\\x^{2}-5x-3300=0\\\\x^{2}+60x-55x-3300=0\\\\x(x+60)-55(x+60)=0\\\\(x-55)(x+60)=0\\\\x=55[/tex]
Compute the time taken by the two trains as follows:
Train P : [tex]t_{P} =\frac{330}{55}=6\ \text{hours}[/tex]

I'm having a hard time figuring this out I've tries multiple ways but can not get it please help
Answer:
9.6
Step-by-step explanation:
Plugging in the info given, we get:
2(4) - (2/5)(-4) = 8 - (-8/5) = 8 + 8/5
From here, you need to make the denominators of both numbers the same in order to combine them further. Currently, as a fraction, it looks like this:
8/1 + 8/5
To make the denominators the same we can just multiply 8/1 by 5/5 (this is the same as multiplying by 1, which essentially allows us to change it's form without changing its value). Doing that gives:
(8/1)(5/5) + 8/5 = (8•5)/5 + 8/5 = 40/5 + 8/5
= (40+8)/5 = 48/5
So 48/5 is the answer. But the website wants you to put it into decimal form. This can be done using a calculator, but let's pretend we don't have one...
Decimals work by using whole numbers divided by multiples of 10 and can be visualized as moving a decimal left (or right) between numbers. For example:
1/10 = 0.1
4/10 = 0.4
23/10 = 2.3
13/100 = 0.13
59/1000 = 0.059 and so on.
So if we can multiply 48/5 by something to make the denominator some multiple of 10, we can simply move the decimal left once and that's our answer. 2/2 should work here:
(48/5)(2/2) = (48•2)/(5•2) = 96/10 or 96.0/10
96.0/10 = 9.6
So your decimal answer is 9.6.

S ≈ 13.08inBella makes the 2.5m distance to her food bowl in 4.1 seconds. What is her average velocity?
Answer:
Bella's average velocity is approximately 0.61 m/s.
Step-by-step explanation:
To find velocity, we divide displacement (in this case, the same as the distance Bella traveled) by the time taken to travel this displacement.
Velocity = displacement/time
If we plug in the given values, we get:
Velocity = 2.5m/4.1s
Velocity = 0.6097561 m/s
Therefore, the correct answer is about 0.61 m/s.
A rectangle's length is 3 more than it width, if the perimeter is 26 inches, what is the width of the
rectangle.
Answer:
So the width is 3.25
Step-by-step
If the perimeter of a rectangle is 300 and the length is two times the
width, what are the length and the width?
Call the width of the rectangle x. Then, if the length is three times the width, the length must be 3x. Now, if you have a rectangle whose width is x and whose length is 3x, the perimeter must be 3x + 3x + x + x = 8x. You are told that the perimeter is 26, so the equation is 8x = 26. Dividing both sides by 8, one gets x = 3.25. So the width is 3.25 and the length is 6.5.*Please don't get upset if this is incorrect, I am in 9th grade and I have severe dyslexia and dyscalculia*

8, 2, -4, - 10,
The equation for the nth term of the arithmetic sequence is -6n + 14 and the found 50 is -286.
What is an arithmetic sequence?An arithmetic sequence is a series of numbers that are ordered and share a common difference between each succeeding term. In the arithmetic sequence 3, 9, 15, 21, 27, for example, the common difference is 6.
Arithmetic is the branch of mathematics that studies numbers by performing various operations on them. A sequence is a numerically ordered list. The three dots indicate that the pattern should be continued. The difference is six.
a + d(n - 1)
a = 8 (first term)
d = -6 (common difference)
8 - 6(n - 1)
= 8 - 6n + 6
= -6n + 14
Find a 50:
-6(50) + 14
= -300 + 14
= -286
Therefore, the equation for the nth term of the arithmetic sequence is -6n + 14.
