Answer:

LCD for 5, 3, 10, 8, 4 is 120

LCD 2, 10, 5, 8, 4 = 40

Step-by-step explanation:

LCD (Least Common Denominator)

When adding fractions with different denominators, we must make all of them equal before attempting to add the numerators.

The minimum number that makes all denominators the same is the LCD. It uses the concept of the Lowest Common Multiple.

To find the LCD for 5, 3, 10, 8, 4, list all their prime factors:

5=5

3=3

10=2,5

8=2,2,2

4=2,2

Now multiply all the prime factors the maximum number of time it appears:

LCD=5*3*2*2*2=120

LCD for 5, 3, 10, 8, 4 is 120

Now for 2, 10, 5, 8, 4

2=2

10=2,5

5=5

8=2,2,2

4=2,2

LCD=2*2*2*5=40

LCD 2, 10, 5, 8, 4 = 40

Answer:

U= 1/2 C V2 = 1/2 (2*10(-6) F)* (5 V)2

Step-by-step explanation:

Answer:

C = 2W/V^2

Step-by-step explanation:

W = 1/2CV^2

W * 2 = 1/2CV^2 * 2

2W/V^2 = CV^2/V^2

2W/V^2 = C

C = 2W/V^2

El total que queda en su cuenta es de $835,56

Step-by-step explanation:

Caja de ahorros: $3.588,90

Lunes

Retira una tercera parte (3588,90 / 3) = $1196,30

Quedan= $2392,60

Martes

Quedaban $2392,60 y se lleva $1000

2392,60 - 1000 = 1392,60

Le quedan= $1392,60

Miércoles

Quedaban $1392,60 y retira 2/5

1392,6 / 5= 278,52 es la quinta parte

-> 2/5 partes son: 278,52 + 278,52 = 557,04

Retira $557,04

1392,60 - 557,04= 835,56

El total que queda en su cuenta es de $835,56

[tex]\huge\boxed{\text{$74$ girls}}\ \huge\boxed{\text{$106$ boys}}[/tex]

Hey there! This situation can be modeled and solved using a system of equations. We'll use [tex]b[/tex] to represent the number of boys and [tex]g[/tex] to represent the number of girls.

[tex]\displaystyle{\left \{ {{b+g&=180} \atop {b&=g+32} \right.}[/tex]

Since we know what [tex]b[/tex] equals, we can substitute it into the first equation.

[tex]\begin{aligned}b+g&=180\\(g+32)+g&=180&&\smash{\Big|}&&\text{Substitute.}\\2g+32&=180&&\smash{\Big|}&&\text{Combine like terms.}\\2g&=148&&\smash{\Big|}&&\text{Subtract $32$ from both sides.}\\g&=74&&\smash{\Big|}&&\text{Divide both sides by $2$.}\end{aligned}[/tex]

Now that we know the number of girls, use the second equation to get the number of boys.

[tex]\begin{aligned}b&=g+32\\&=74+32&&\smash{\Big|}&&\text{Substitute.}\\&=106&&\smash{\Big|}&&\text{Add.}\end{aligned}[/tex]

Answer:

La ecuación de la trayectoria circular del avión es x² + y² = 9

Step-by-step explanation:

La forma general de la ecuación de un círculo se da como sigue;

(x - h)² + (y - k)² = r²

Dónde;

(h, k) = El centro del círculo

r = El radio del círculo

Dado que la distancia del avión a la torre es constante, tenemos la trayectoria del avión = trayectoria circular

El radio, r de la trayectoria circular = 3 km

Por lo que la trayectoria circular del avión se va a definir con respecto a la torre de control, tenemos;

El centro de la trayectoria circular del avión = La torre

Las coordenadas del centro de la trayectoria circular = (0, 0)

Por lo tanto, (h, k) = (0, 0)

Sustituyendo los valores conocidos, la ecuación de la trayectoria circular del avión se convierte en;

(x - h)² + (y - k)² = r² → (x - 0)² + (y - 0)² = r² = x² + y² = 3² = 9

La ecuación de la trayectoria circular del avión. = x² + y² = 9

Answer:

10%

Step-by-step explanation:

Original price of flutes = $770

Discounted price = $693

To find:

Discount percentage = ?

Solution:

To find the discount percentage, we need to first find out the discount value.

Discount = Original price of flutes - Discounted price of flutes

Discount = $770 - $693 = $77

Discount percentage will be calculated on the original price.

[tex]Discount \%=\dfrac{Discount}{Original\ Price}\times 100\\\Rightarrow Discount \%=\dfrac{77}{770}\times 100\\\Rightarrow Discount \%=\bold{10\%}[/tex]

So, the discount as a percentage is 10%.

Answer:

Step-by-step explanation:

A) C(7) represents the cost of an Uber for 7 miles. Since 'm' is the cost for m miles, '7' is the cost for 7 miles.

B) If Todd's total bill was $30, that means the cost (C) is 30. Replace C with 30.

30 = 1.5m+4.5

Now solve this equation.

30-4.5 = 1.5m+4.5-4.5

25.5 = 1.5m

m = 17

If Todd's total bill was $30, his Uber ride was 17 miles.

Answer:

Step-by-step explanation:

A. y < 5/3 x-2

B. y < -5/3 x + 1

C. y > 5/3 x + 2

D. y > -5/3 x + 2

[tex]y > \frac 53x +2[/tex] will not have a shared solution set with the graphed linear inequality

From the graph, we have the equation of the line to be:

[tex]y < \frac 53x +1[/tex]

The equation that have a shared solution must intersect with the line of the inequality.

From the list of options, we have:

[tex]y < \frac 53x -2[/tex] --- has the same slope, but a smaller y-intercept.

This means that the region of [tex]y < \frac 53x -2[/tex] is within the region of [tex]y < \frac 53x +1[/tex]

[tex]y < -\frac 53x + 1[/tex]

This has a different slope to the graph.

So, it will have a shared solution

[tex]y > \frac 53x +2[/tex] --- has the same slope, but a bigger y-intercept and a different inequality sign

This means that the region of [tex]y > \frac 53x +2[/tex] is outside the region of [tex]y < \frac 53x +1[/tex], and it will not have a shared solution

Hence, [tex]y > \frac 53x +2[/tex] will not have a shared solution set with the graphed linear inequality

Answer: A. it’s parallel

Step-by-step explanation:

just did my test.

The statement that must be true to prove m∠1 + m∠2 + m∠3 = 180

m∠1 + m∠2 = 180 - m∠3

Option B is the correct answer.

It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.

We have,

m∠1 + m∠2 = 180 - m∠3

m∠1 + m∠2 + m∠3 = 180

Thus,

m∠1 + m∠2 = 180 - m∠3 is m∠1 + m∠2 + m∠3 = 180.
