Professor Walter precisa pintar uma quadra, que tem o formato retangular, cujo comprimento é de 45 m por 38 m. Para isso ele vai comprar baldes de tinta em uma loja de construção. Sabendo que com cada balde de tinta ele conseguirá pintar 72 m² de piso, quantos baldes de tinta ele precisará comprar

Answers

Answer 1

Answer:

24 buckets

Step-by-step explanation:

Given that :

Dimension of rectangular block = 45 m by 38 m

A bucket of paint will cover 72m² of floor

Total area of floor : Length * Width

Total Area = (45m * 38m) = 1710 m²

Buckets of paint required :

Total area / Area per bucket

= 1710m² / 72m²

= 23.75 buckets

= 24 buckets

11 Karl takes a ride in a taxi and is charged $2.75 for the first of a mile. He is charged $0.25 for each
additional to
of a mile traveled and gives the driver a $3.50 tip. Explain how to determine the number of
miles that Karl can ride in the taxicab for a total of $28.50 including the tip. Show your work.


I WILL GIVE HIGH POINTS JUST PLEASE HELP SOON.

Answers

Answer: 89 miles


Explanation: We can make a linear equation given the problem, where 2.75 is the constant and 0.25 is the slope. M can represent miles 28.5 is what we want the equation to equal, so it will be on one side of the equation.

We can simply add the $3.50 tip to the constant to account for it

Thus we have 28.50=0.25m+6.25.

Solving for m gives us 89 miles.

The diagram below shows a map of the routes taken by Georgia Air-Taxi airline. On this diagram lengths and directions are irrelevant, all that matters is the connections between airports. Choose the adjacency matrix, name it A, that matches the scenario.

Answers

Answer: B

Step-by-step explanation: Adjacency Matrix is a square matrix representing a simple graph with 0 or 1 according to the condition given.

In this diagram, 0 corresponds to no connection between airports and 1 corresponds to connections between airports.

In other words, analysing the image, we see that:

1) Albany just have connection with Atlanta, so in the position of line Albany with column At, it must be a 1. The other columns, there are 0.

The Line for Albany in the matrix will be: [0 1 0 0 0 0]

2) Atlanta has connections with Albany, Dalton, Macon and Augusta. So corresponding position (line and column) must be 1. The only two airports Atlanta doesn't have connection with its own and Waycross, so at the corresponding column and line, it is written 0.

The line for Atlanta in the matrix is [1 0 1 1 1 0]

3) Augusta: connections with Atlanta, Macon, Waycross. At those positions, it will be written 1. At positions related to itself, Albany and Dalton is 0.

The line in the matrix will be [0 1 0 0 1 1]

4) Dalton: connection with Atlanta only. That position will be 1 while the others will be 0.

The line is [0 1 0 0 0 0]

5) Macon: connections with Atlanta, Augusta and Waycon: those positions will have 1 and the other 0.

The line is [0 1 1 0 0 1]

6) Waycross: connections with Macon and Augusta. Those positions will be 1 and the others 0.

The line is [0 0 1 0 1 0]

In conclusion, the adjacency matrix matching the scenario is

[tex]A=\left[\begin{array}{cccccc}0&1&0&0&0&0\\1&0&1&1&1&0\\0&1&0&0&1&1\\0&1&0&0&0&0\\0&1&1&0&0&1\\0&0&1&0&1&0\end{array}\right][/tex]

Jaxon is deciding between two landscaping companies for his place of business. Company A charges $45 per hour and a $150 equipment fee. Company B charges $35 per hour and a $200 equipment fee. Let AA represent the amount Company A would charge for tt hours of landscaping, and let BB represent the amount Company B would charge for tt hours of landscaping. Write an equation for each situation, in terms of t,t, and determine the interval of hours, t,t, for which Company A is cheaper than Company B.

Answers

Answer:

When the number of hours t is less than 5 hours, Company A is cheaper than Company B

Step-by-step explanation:

Let the number of hours be represented by t

For Company A

Company A charges $45 per hour and a $150 equipment fee.

150 + 45t

For Company B

Company B charges $35 per hour and a $200 equipment fee.

200 + 35t

Write an equation for each situation, in terms of t,t, and determine

The interval of hours,t, for which Company A is cheaper than Company B is given as:

Company A < Company B

Hence:

150 + 45t < 200 + 35t

Collecting like terms

45t - 35t < 200 - 150

10t < 50

t< 50/10

t < 5

When the number of hours t is less than 5 hours, Company A is cheaper than Company B

Gwen scans a photo that is 4 in. wide by 6 in. tall into her computer. If she scales the
height down to 3 in., how wide should the similar photo be?

Answers

Answer: 2 inches in width

Step-by-step explanation:

4 - 6

divide both by 2

2 - 3

The width of a similar photo comes to be 2 inches.

Width of original photo = 4 inches

Height of the original photo = 6 inches

Height of the scaled photo = 3 inches

What is the scale factor?

A scale factor is a number that multiplies (“scales”) a quantity.

Scale factor = height of scaled photo/ height of the original photo

Scale factor= 3/6 = 1/2

So, the width of the scaled photo = scale factor * width of the original photo

The width of the scaled photo = (1/2)*4

The width of the scaled photo =2 inches.

Therefore, the width of a similar photo comes to be 2 inches.

P is the principal amount, $200.00.

r is the interest rate, 2% per year, or in decimal form, 2/100=0.02.

t is the time involved, 15....year(s) time periods.
