Answer:

Step-by-step explanation:

For this, you want to find the greatest common factor

This basically means what number can be divided out of all of these.

So, you can find the factors for all of them and find which one appears in all three numbers and which is the greatest number

for 12:

1, 2, 3, 4, 6, 12

For 20:

1, 2, 4, 5, 10, 20

For 56:

1, 2, 4, 7, 8, 14, 28, 56

The numbers that appear in all of there are:

1, 2, and 4

And since we want to find the greatest amount she can charge for bracelet, the answer is:

A family of 2 adults and 4 children is going to an amusement park. Admission is a 21 point 75 for adults and 15 point 25 for chi

Juliette [100K]

Answer:

Step-by-step explanation:

The number of adults in the family that is going to the amusement park is 2.

The number of children in the family that is going to the amusement park is 4.

Admission is a 21 point 75 for adults and 15 point 25 for children. This means that the admission cost for each adult is 21.75 and the admission cost for each adult is 15.25. Therefore,

The total cost of admission for the 2 adults would be

21.75 × 2 = 43.5

The total cost of admission for the 4 children would be

15.25 × 4 = 61

Therefore, the total cost of the families admission would be

43.5 + 61 = 104.5

The velocity of an object is given by the following function defined on a specified interval. Approximate the displacement of th

harkovskaia [24]

Answer:

The displacement of the object on this intervals is 1.33 m.

Step-by-step explanation:

Given that,

The function of velocity is

$v=\dfrac{1}{2t+4}\ m/s$

For 0 ≤ t ≤8 , n = 2

We need to calculate the intervals

Using formula for intervals

For, n = 1

$\Delta x=\dfrac{t_{f}-t_{i}}{n}$

$\Delta x=\dfrac{8-0}{2}$

$\Delta x=4$

So, The intervals are (0,4), (4,8)

We need to calculate the velocity

Using given function

$v=\dfrac{1}{2t+4}$

For first interval (0,4),

Put the value into the formula

$v_{0}=\dfrac{1}{2\times0+4}$

$v_{0}=\dfrac{1}{4}$

For first interval (4,8),

Put the value into the formula

$v_{4}=\dfrac{1}{2\times4+4}$

$v_{4}=\dfrac{1}{12}$

We need to calculate the total displacement

Using formula of displacement

$D=(v_{0}+v_{4})\times(\Delta x)$

Put the value into the formula

$D=(\dfrac{1}{4}+\dfrac{1}{12})\times4$

$D=1.33\ m$

Hence, The displacement of the object on this intervals is 1.33 m.

Solve for x: Log4(x+8)=3

viktelen [127]

If $log_{4}(x+8)=3$
Then $4^3=x+8$
$64=x+8$
$64-8=x$
$56=x$

Write a two column proof (or a flow proof. Whichever one works for you).

Norma-Jean [14]

Plugging into the Given Formula the value of y:

$7(6) = 8x - 14$

Multiply the left side:

$42 = 8x - 14$

Add 14 to both sides to get:

$56 = 8x$

Divide both sides by 8 and we get:

$7 = x$

Therefore, x=7 and the proof is complete

Is the expression 5y-10 equivalent to 5(y-2

KonstantinChe [14]

Answer:

Yes, they are equivalent.

Step-by-step explanation:

They are equivalent, to see this, simplify the expression.

Distribute into the parenthesis.

5(y)- 5(2)

Then simplify into...

5y-10

This is equivalent to 5y-10
