$\bf \cfrac{1}{3}\sqrt[3]{81}\implies \cfrac{1}{3}\sqrt[3]{3^4}\implies \cfrac{1}{3}\sqrt[3]{3^{3+1}}\implies \cfrac{1}{3}\sqrt[3]{3^3\cdot 3^1}\implies \cfrac{1}{3}\cdot 3\sqrt[3]{3^1}
\\\\\\
\sqrt[3]{3}$

A girls' choir is choosing a concert uniform. They can pick red, green, or purple sweaters, and they can pick tan or black skirt

Fynjy0 [20]

<h3>Answer: C) 12</h3>

======================================================

Explanation:

There are 3 colors of sweaters {red, green, purple} and 2 colors of skirts {tan, black}

So far there are 3*2 = 6 different outfit combinations. Imagine a table with 3 rows representing the sweater colors and 2 columns representing the skirt colors. There would be 6 cells in the table representing each possible combination. One cell would have (red sweater, tan skirt) for instance.

For each of those 6 combinations, we also have 2 shoe colors. So overall we have 6*2 = 12 outfit combinations

The tree diagram is shown below. Note how there are 3*2*2 = 12 different paths to follow.

ChitChat Wireless charges $0.30 per minute plus a monthly base fee. In September, Maggie used 120 minutes and her bill was $51.

SVEN [57.7K]

Answer:

$C = 0.30(m) + 15

C is bill cost

m is number of minutes used

Step-by-step explanation:

In this question, we are asked to write an equation that estimates the bill cost of Maggie’s phone bills.

We proceed as follows;

Now, let’s try and find the base fee.

We can calculate this using her bill for September.

Mathematically;

Bill = (Cost per minute * total minutes) + Base fee

Here, $0.30 per minute for 120 minutes will yield a total of 120 * 0.3 = $36

This means the base fee would be $51-$36 = $15

Now let’s say the bill is $C, and the number of minutes used is m

Mathematically;

$C = 0.30(m) + 15

For the given polynomial P(x) and c=1/2 use the remainder theorem to find P(c).

Aleonysh [2.5K]

Answer:

-2.90625

Step-by-step explanation:

Given the polynomial function

P(x) = x^5-x^4+x^3-3

If c = 1/2

At x = c

P(1/2) = (1/2)^5-(1/2)^4+(1/2)^3-3

P(1/2) = 1/32 - 1/16 + 1/8 - 3

P(1/2) = 1-2+4-96/32

P(1/2) = -93/32

P(1/2) = -2.90625

Hence P(c) is -2.90625
