Answer:
why should the government provides security to it's people
Answer: 2205
Step-by-step explanation:
From the prime factorisation of 525 we get
525 = 3×5×5×7
We have to make sure that all the factors are in cube form
To do that we have to add 3×3×5×7×7 to the factors
We get
525 = 3×3×3×5×5×5×7×7×7
So the 3×3×5×7×7 gives us the smallet value of k, which is 2205
And 525×2205 gives us 1157625 which is a perfect cube.

Answer:
[tex]\huge\boxed{\sf <WVT = 40\°}[/tex]
Step-by-step explanation:
According to one of the tangent-secant theorems,
∠WVT = [tex]\frac{1}{2} (arc\ TW-arc\ UW)[/tex]
Given that:
∠WVT = (3x + 4)°
arc TW = (14x + 7)°
arc UW = (7x + 11)°
Solution:
3x + 4 = 1/2 (14x + 7 - (7x + 11))
3x + 4 = 1/2 (14x + 7 - 7x - 11)
3x + 4 = 1/2 ( 7x - 4 )
Multiply both sides by 2
2 ( 3x + 4 ) = 7x - 4
6x + 8 = 7x - 4
Combining like terms
7x - 6x = 8 + 4
x = 12
Finding ∠WVT:
∠WVT = (3x + 4)°
∠WVT = (3(12)+4)°
∠WVT = (36+4)°
∠WVT = 40°

~AH1807Peace!The area of a rectangular swimming pool is 240 sq. ft. If the length of the swimming pool is 10 ft. and the width is x-2 ft., what is the value of x?
Answer:
x= 26
Step-by-step explanation:
area of rectangle = L×b
240 = 10(x-2)
240 = 10x - 20
240+20 =10x
260 =10x
260/10 = x
26 = x
:,x =26
The required value of x is 26

NOTE : answer only the 2nd question
Answer:
60 degrees.
Step-by-step explanation:
BC is parallel to the x axis (because B and C have the same y-coordinate).
Slope of AB is 3/√3 = √3
so the angle AB makes with the axis = angle it makes with BC
= arctan(√3)
= 60 degrees.
Margarita entrena tres semanas para participar en un maratón. En la segunda semana recorre 1 km más que en la primera y en la tercera semana, corre el doble de km que los corridos en la segunda, ¿cuál es la representación algebraica simplificada de los kilómetros recorridos durante el entrenamiento?
Queremos encontrar una expresión algebraica que representa la situación dada.
Encontraremos que está es: 4*D + 3
Lo primero que debemos hacer es definir la variable.
Definamos D como la distancia que Margarita recorre en la primer semana.
En la segunda semana, Margarita recorre un kilometro más que en la primera, entonces en la segunda semana Margarita recorre:
D + 1km
En la tercera semana, Margarita recorre el dolbe de km recorridos en la segunda.
En la segunda ella recorrio D + 1km, y el doble de eso es:
2*(D + 1km) = 2*D + 2km
La distancia total recorrida sera la suma de las 3 semanas:
D + (D + 1km) + (2*D + 2km)
Simplificando los km, así solo queda una expresión algebraica, obtenemos:
D + (D + 1) + (2*D + 2)
Podemos simpliicar esto para obtener:
D + D + 1 + 2*D + 2
(D + D + 2*D) + (1 + 2)
4*D + 3
Entonces la representación algebraica simpliicada de los kilómetros recorridos durante el entrenamiento es:
4*D + 3

If m<3 = 54°, find each measure.
m<1 = 36° (str. <s)
m<2 = 90°
m<4 = 36° (str. <s)
m<5 = 90° (vert. opp. <s)
m<6 = 54° (vert. opp. <s)
m<7 = 126° (str. <s)
m<8 = 54° (< sum of triangle)
m<9 = 126° (vert. opp. <s)
m<10 = 54° (vert. opp. <s)
m<11 = 36° (alt. <s)
m<12 = 144° (str. <s)

Evaluate \dfrac {9}m+4 m 9 +4start fraction, 9, divided by, m, end fraction, plus, 4 when m=3m=3m, equals, 3.
Fractions can be evaluated, same way non fractions are evaluated

The given parameters are:
[tex]\mathbf{\dfrac {9}m+4}[/tex]

Answer:
see explanation
Step-by-step explanation:
Since AL bisects ∠ KAT then ∠ 1 = ∠ 2
(30)
7x + 3 = 6x + 7 ( subtract 6x from both sides )
x + 3 = 7 ( subtract 3 from both sides )
x = 4
(32)
SAT is a straight line , then
∠ 1 + ∠ 2 + ∠ 3 = 180° , then
x + x + 4x = 180
6x = 180 ( divide both sides by 6 )
x = 30
(34)
Similar to (32)
x + 12 + x + 12 + 6x - 20 = 180 , that is
8x + 4 = 180 ( subtract 4 from both sides )
8x = 176 ( divide both sides by 8 )
x = 22
Answer:
30) x= 4
32) x=30
33) x=22

Use the graph of f to find F(2).
A. 0.5
B. Does not exist
C. -8
D. -0.5
Hey there! Before we start with the problem, you mean f(2) instead of F(2) if I'm correct. In maths, variables are case-sentitive so F and f both are different.
First, f(2) means the value of y at x = 2.
f(2) is when we substitute x = 2 in and receive the output (y-value).
In coordinate plane, we have (x,y) as a point. What we have to do is to look at the graph, you will see the point that contains (2,-8)
That's it! Refer above, f(2) is when we substitute x = 2 and get y-value.
Hence, f(2) = -8

If the canary flies 120 km per hour and spends no time to turn around at each car, how far has it flown when the cars collide?
