Answer:

B

Step-by-step explanation:

The closed circle at - $\frac{3}{2}$ indicates that x can equal this value

The open circle at $\frac{7}{2}$ indicates that x cannot equal this value.

All values of x between - $\frac{3}{2}$ and $\frac{7}{2}$ are valid, thus

- $\frac{3}{2}$ ≤ x < $\frac{7}{2}$ → B

Roxy is multiplying 1/8 by 4/3

Vera_Pavlovna [14]

Answer:

1/6

Step-by-step explanation:

Make the denominators the same by finding the lcm(least common denominator). The least common demominator would be 24. So multiply both numbers in 1/8 by 3. This would eaqual 3/24. Multiply both numbersin 4/3 by 8. This would equal $\frac{3}{24} * \frac{32}{24}$ = $\frac{96}{576}$ . Simplify 96/576 by dividing both numbers by 96.

<u>96</u> ÷ 96 = <u> 1 </u> 576 ÷ 96 = 6 and that becomes 1/6.

Dividing a power of 4 by 4 is equivalent to (dividing, increasing, reducing, multiplying) the exponent by (10, 2, 1, 4).

Lina20 [59]

Answer:

Dividing a power of 4 by 4 is equivalent to ( reducing,) the exponent by (1).

Step-by-step explanation:

Let the power of 4 be 3

4 *4*4

We divide by 4

4*4*4/4 = 4*4 = 4^2

So we removed 1 power

Notice that 3-1 =2

Let 4 be raised to any power

4^a

We divide by 4

4^a/4 we remove 1 of the powers

we are left with

4^(a-1)

So we reduce the exponent by 1

Kyle's birthday party in 2007 cost $d$ dollars per person and $p$ people attended. In 2008, the cost per person doubled and the

OlgaM077 [116]

Answer: The ratio of the total cost of the party in 2007 to the total cost of the party in 2008 = 1: 4

Step-by-step explanation:

It is given that Kyle's birthday party in 2007 cost $d$ dollars per person and $p$ people attended.

Then , the total cost of the party = Cost per person x Number of people attended.

For 2007, Total cost = d x p = dp (1)

In 2008, the cost per person doubled and the number of people attending the party also doubled.

i.e. Cost per person = 2d

Number of people attended = 2p

For 2008, Total cost = 2d x 2p = 4dp (2)

From (1) and (2) , the ratio of the total cost of the party in 2007 to the total cost of the party in 2008 will be :

$\dfrac{pd}{4pd}$

Cancel pd from the numerator and the denominator , we get $\dfrac{1}{4}$

Hence, the ratio of the total cost of the party in 2007 to the total cost of the party in 2008 = 1: 4
