Mr. Holloway is a craftsman who makes custom guitars by hand. His last order was for 2 guitars, and it took him 8 weeks to make

o-na [289]

Answer:

It took Mr. Holloway 28 weeks to make 7 guitars.

Step-by-step explanation:

The question is incomplete, but if we are trying to find out how many weeks it would take him to make 7 guitars then the answer would be 28.

First you have to find out how many weeks it takes him to make 1 guitar.

8 ÷ 2 = 4 (4 weeks to make 1 guitar)

Then you have to multiply 4 by 7 since it takes 4 weeks to make 1 guitar.

4 * 7 = 28 (28 weeks to make 7 guitars)

Write the first five terms of the sequence defined by the explicit formula.

AlexFokin [52]

Answer:

(a) 112, 28, 7, (7/4), (7/16)

Step-by-step explanation:

The sequence is given by the explicit formula

$a_{n} = 112 (\frac{1}{4} )^{n-1}$

The terms of the sequence are :

$a_{1} = 112 (\frac{1}{4} )^{1-1} = 112 (\frac{1}{4} )^{0} =112$

$a_{2} = 112 (\frac{1}{4} )^{2-1} = 112(\frac{1}{4} ) =28$

$a_{3} = 112 (\frac{1}{4} )^{3-1} = 112(\frac{1}{4} )^{2} = 7$

$a_{4} = 112 (\frac{1}{4} )^{4-1}=112(\frac{1}{4} )^{3} = \frac{7}{4}$

$a_{5} = 112 (\frac{1}{4} )^{5-1}=112 (\frac{1}{4} )^{4} = \frac{7}{16}$

Mike took clothes to the cleaners three times last month. First, he brought 4 shirts and 1 pair of slacks and paid $15.95. The

Vsevolod [243]

Answer:

Each Shirt ≈ $2.49

Each Pair of Slacks ≈ $5.99

Each Sports Coat ≈ $7.99

Step-by-step explanation:

Mike took clothes to the cleaners three times last month.

Let S denotes shirts, P denotes pair of slacks and C denotes sports coat.

First, he brought 4 shirts and 1 pair of slacks and paid $15.95.

Mathematically,

4S + P = 15.95 eq. 1

Then he brought 7 shirts, 4 pairs of slacks, and 1 sports coat and paid $49.38.

Mathematically,

7S + 4P + C = 49.38 eq. 2

Finally, he brought 3 shirts and 1 sports coat and paid $15.46.

Mathematically,

3S + C = 15.46 eq. 3

We are asked to find how much was he was charged for each shirt, each pair of slacks, and each sports coat.

4S + P + 0C = 15.95 eq. 1

7S + 4P + C = 49.38 eq. 2

3S + 0P + C = 15.46 eq. 3

We have 3 equations and 3 unknowns, they can be solved simultaneously using calculator or using online system of equations solver.

Using online system of equations solver yields,

S ≈ $2.49

P ≈ $5.99

C ≈ $7.99

So that means Mike was charge $2.49 for each shirt, $5.99 for each pair of slacks and $7.99 for each sports coat.

Hey can you please help me posted picture of question

The answer is True.

A compound event is one in which there is more than one possible outcome. It is also defined as a probabilistic event with two or more favorable outcomes. For example, when you throw a die (singular for dice), it is called a simple event. On the other hand, when you throw a dice, it is known as a compound event.
