Answers

Answer 1

Answer:

Perimeter of ABCD - Perimeter of PQRS = 4x + 2

Step-by-step explanation:

i. For rectangle ABCD;

length, l = 2x -3

width, w = 4x + 5

Perimeter of a rectangle = 2(l + w)

Perimeter of ABCD = 2((2x -3) + (4x + 5))

                                = 2(2x -3 + 4x + 5)

                                = 2(6x + 2)

Perimeter of ABCD = 12x + 4

ii. For rectangle PQRS;

length, l = x - 1

width, w = 3x + 2

Perimeter of a rectangle = 2(l + w)

Perimeter of PQRS = 2((x - 1) + (3x + 2))

                                = 2(x - 1 + 3x + 2)

                                = 2(4x + 1)

Perimeter of PQRS = 8x + 2

So that,

Perimeter of ABCD - Perimeter of PQRS = (12x + 4) - (8x + 2)

                                          = 12x + 4 - 8x - 2

                                          = 4x + 2

Perimeter of ABCD - Perimeter of PQRS = 4x + 2

The number of visits to public libraries increased from 1.3 billion in 1998 to 1.5 billion in 2002. Find the average rate of change in the number of public library visits from 1998 to 2002.

Answers

Answer:

A = 0.05 billion visits per year

Step-by-step explanation:

Given that,

The number of visits to public libraries increased from 1.3 billion in 1998 to 1.5 billion in 2002.

We need to find the average rate of change in the number of public library visits from 1998 to 2002.

So,

[tex]A=\dfrac{1.5-1.3}{2002-1998}\\\\A=0.05\ \text{billion visits per year}[/tex]

Hence, the required average rate is 0.05 billion visits per year.

The constant velocity motion formula can be expressed as x = x0 + vt

where x is the location of the object at time t, xo is where the object begins, and v is the constant velocity. This is an example of a linear equation.

Suppose we’re collecting data on an object that we know has a constant velocity. We observe the object being 40m away from us at time 4. 10 seconds later at time 14, we make another observation and notice the object is now 70m away.


Using this data, and the constant velocity motion formula, determine an equation that models the object’s path.

Answers

Answer and Step-by-step explanation: With the constant velocity motion formula, we can determine constant velocity of the object in motion whose data we collected:

x = x₀ + vt

Velocity can be calculated as:

[tex]v=\frac{x-x_{0}}{t}[/tex]

[tex]v=\frac{70-40}{10}[/tex]

v = 3 m/s

The beginning of the data collect, object is 40m away, then x₀ = 40.

So, equation modeling the object's path is x = 40 + 3t.

at a hot dog stand they serve regular and footlong hot dogs at a ratio of 5 to 3 based on this ratio how many footlongs hot dogs will be served there is a total of 120 hot dogs served. A. 45 footlong hot dogs, B. 75 footlong hot dogs, C. 72 footlong hot dogs​

Answers

Answer:

45

Step-by-step explanation:

Ratio is 5:3

So total ratio "parts" is 5 + 3 = 8

In total there are 120 dogs served, so each part is:

120/8 = 15 dogs

Since, footlong hot dogs are "3" parts, and each part is 15 dogs, there will be:

3 * 15 = 45 footlong hotdogs

a printing service charges a set up fee of 11.00 for each order and 10 cents more for each copy . the totsl cost, C (in dollars), for an order of x copies is given by the following . C= 11.00+ 0.10x
What is the total cost for an order of 20 copies ?

Answers

Answer:

$13.00

Step-by-step explanation:

First, you plug in your x value for copies into the equation C=11.00+0.10x to get a starting equation of x=11.00+0.10(20). Since 0.10 is equivalent to 1/10, it's easy to compute (1/10)(20)=2. You now have an equation of C=11.00+2.00 to get C=13.00. Therefore, the total cost for an order of 20 copies is 13 dollars (and 0 cents).

Abigail is incorrect and the correct ratio of  the number of boys in 6th grade to the number of girls in 6th grade is 3:4

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given,

The number of boys in 6th grade is 30

The number of girls in 6th grade is 40.

The  ratio of the number of boys in 6th grade to the number of girls in 6th grade is 30:40

30/40

Divide numerator and denominator by 10

Read the following passage and answer the question that follows: from Metamorphosis by Franz Kafka (1) One morning, when Gregor Samsa woke from troubled dreams, he found himself transformed in his bed into a horrible vermin. He lay on his armour-like back, and if he lifted his head a little he could see his brown belly, slightly domed and divided by arches into stiff sections. The bedding was hardly able to cover it and seemed ready to slide off any moment. His many legs, pitifully thin compared with the size of the rest of him, waved about helplessly as he looked. (2) "What's happened to me?" he thought. It wasn't a dream. His room, a proper human room although a little too small, lay peacefully between its four familiar walls. A collection of textile samples lay spread out on the tableSamsa was a travelling salesmanand above it there hung a picture that he had recently cut out of an illustrated magazine and housed in a nice, gilded frame. It showed a lady fitted out with a fur hat and fur boa who sat upright, raising a heavy fur muff that covered the whole of her lower arm towards the viewer. (3) Gregor then turned to look out the window at the dull weather. Drops of rain could be heard hitting the pane, which made him feel quite sad. "How about if I sleep a little bit longer and forget all this nonsense," he thought, but that was something he was unable to do because he was used to sleeping on his right, and in his present state couldn't get into that position. However hard he threw himself onto his right, he always rolled back to where he was. He must have tried it a hundred times, shut his eyes so that he wouldn't have to look at the floundering legs, and only stopped when he began to feel a mild, dull pain there that he had never felt before.
