Answer: 32

Step-by-step explanation:

4 dozen beads is 48 beads. Divide 48 into 6 groups, and your answer is 8. If Rosa gave 2 groups to her friend, she gave 16 beads, which leaves her with 32 beads.

Answer: 32

Step-by-step explanation:

1 dozen = 12.

4 dozen x 12 = 48.

48 ÷ 6 = 8

If she gave two groups of 8 beads, that is 16 beads.

48 beads - 16 beads = 32 beads.

The answer is 32 beads.

A basic cellular package costs $20 per month for 60 minutes of calling, with an additional charge of $0.20/min beyond that time.
Anika [276]

Answer: you can use 260 min, 60 min at a fixed price ($20) and extra 200.

Step-by-step explanation:

C(x) = 20 + 0.20(x − 60)

C(x) ≤ 60

20 + 0.20(x − 60) ≤ 60

0.20(x − 60) ≤ 60 - 20

0.20x - 12 ≤ 40

0.20x ≤ 40 + 12

0.20x ≤ 52

x ≤ 52/0.2

x ≤ 260

This way, you can use 260 min, 60 min at a fixed price ($20) and extra 200.

If a(x) = 3x + 1 and b (x) = square root of x-4, what is the domain of (b o a)(x)
Monica [59]

( 1, ∞)  is the domain of (b o a)(x)

<h3>What is Function?</h3>

A function is defined as a relation between a set of inputs having one output each.

According to the question,

a(x) = 3x + 1 \\\\b (x) =\sqrt{x+4}

To find the domain of the composite function,

(b o x) (x) = b(a(x))\\\\(b o x) (x) = b(a(3x-1))\\\\(b o x) (x) = \sqrt{3x+ 1 -4} \\\\(b o x) (x) = \sqrt{3x -3}\\\\

Therefore,

3x - 3 \geq 0\\3x \geq 3\\x \geq 1\\\\

Hence , [ 1, ∞ ] is is the domain of (b o a)(x).
