When an amount of heat Q (in kcal) is added to a unit mass (kg) of a
substance, the temperature rises by an amount T (°C). The quantity dQ/dT, called
specific heat, is 0.18 (kcal/°C) for glass. If dQ/dt = 12.9 kcal/min for a 1 kg sample
of glass at 20.0 °C, find dT/dt for this same sample. (Note: T is for temperature, t is
for time.)

Answers

Answer:

The change in temperature per minute for the sample, dT/dt is 71.[tex]\overline {6}[/tex] °C/min

Step-by-step explanation:

The given parameters of the question are;

The specific heat capacity for glass, dQ/dT = 0.18 (kcal/°C)

The heat transfer rate for 1 kg of glass at 20.0 °C, dQ/dt = 12.9 kcal/min

Given that both dQ/dT and dQ/dt are known, we have;

[tex]\dfrac{dQ}{dT} = 0.18 \, (kcal/ ^{\circ} C)[/tex]

[tex]\dfrac{dQ}{dt} = 12.9 \, (kcal/ min)[/tex]

Therefore, we get;

[tex]\dfrac{\dfrac{dQ}{dt} }{\dfrac{dQ}{dT} } = {\dfrac{dQ}{dt} } \times \dfrac{dT}{dQ} = \dfrac{dT}{dt}[/tex]

[tex]\dfrac{dT}{dt} = \dfrac{\dfrac{dQ}{dt} }{\dfrac{dQ}{dT} } = \dfrac{12.9 \, kcal / min }{0.18 \, kcal/ ^{\circ} C } = 71.\overline 6 \, ^{\circ } C/min[/tex]

For the sample, we have the change in temperature per minute, dT/dt, presented as follows;

[tex]\dfrac{dT}{dt} = 71.\overline 6 \, ^{\circ } C/min[/tex]

Regina bought a handmade quilt at original cost $120 to sell in her quilt store. She marked the price up 55%.

Answers

Answer:

[tex]Selling\ price = \$190.65[/tex]

Step-by-step explanation:

Given

[tex]Price = \$123[/tex]

[tex]Marked\ up = 55\%[/tex]

Required

The selling price

This is calculated as:

[tex]Selling\ price = Price + Marked\ up* Price[/tex]

[tex]Selling\ price = \$123 + 55\% * \$123[/tex]

[tex]Selling\ price = \$123 + \$67.65[/tex]

[tex]Selling\ price = \$190.65[/tex]

Answer:

$66.00

Step-by-step explanation:

We are asked to find the amount of markup on Regina's quilt. The amount of markup is given by

markup rate×original price=amount of markup.

The markup rate is in decimal form.

Since the original price was $120, and the markup rate is 55%=0.55, we have

0.55×120=66.

Thus, the amount of markup on Regina's quilt was $66.00.

A six-sided number cube labeled 1 through 6 is rolled 600 times. An odd number is rolled 272 times. Compare the experimental probability of rolling an odd number with the relative frequency of rolling an odd number and select one of the statements below that best describes the situation. (5 points)

a
The experimental probability and relative frequency are the same.

b
The experimental probability is larger than the relative frequency.

c
The experiment probability is smaller than the relative frequency.

d
There is not enough information to determine the relative frequency.

Answers

Answer:

Relative frequency is defined as the number of "desired" results divided by the total number of possible results. Experimental probability is defined the same way. This means that the first choice is best, the experimental probability and relative frequency are the same.

The theoretical probability, on the other hand, would be 0.5, or 300/600, which is larger than the experimental probability.

Step-by-step explanation:

If n is a positive integer, how many 5-tuples of integers from 1 through n can be formed in which the elements of the 5-tuple are written in increasing order but are not necessarily distinct? In other words, how many 5-tuples of integers (h, i, j, k, m) are there with 1 ≤ h ≤ i ≤ j ≤ k ≤ m ≤ n? As in Example 9.6.3, you can represent any ordered 5-tuple of integers (h, i, j, k, m) with 1 ≤ h ≤ i ≤ j ≤ k ≤ m ≤ n as a string of n − 1 vertical bars and 5 crosses, with the position of crosses indicating which 5 integers from 1 to n are included in the 5-tuple. Thus, the number of 5-tuples is the same as the number of strings of n+4 vertical bars and 5 crosses, which is n(n+1)(n+2)(n+3)(n+4) 120 .

Answers

Answer:

[tex]\frac{(n+4)*(n+3)*(n+2)*(n+1)*n}{120}[/tex]

Step-by-step explanation:

Given

5 tuples implies that:

[tex]n = 5[/tex]

[tex](h,i,j,k,m)[/tex] implies that:

[tex]r = 5[/tex]

Required

How many 5-tuples of integers [tex](h, i, j, k,m)[/tex] are there such that[tex]n\ge h\ge i\ge j\ge k\ge m\ge 1[/tex]

From the question, the order of the integers h, i, j, k and m does not matter. This implies that, we make use of combination to solve this problem.

Also considering that repetition is allowed: This implies that, a number can be repeated in more than 1 location

So, there are n + 4 items to make selection from

The selection becomes:

[tex]^{n}C_r => ^{n + 4}C_5[/tex]

[tex]^{n + 4}C_5 = \frac{(n+4)!}{(n+4-5)!5!}[/tex]

[tex]^{n + 4}C_5 = \frac{(n+4)!}{(n-1)!5!}[/tex]

Expand the numerator

[tex]^{n + 4}C_5 = \frac{(n+4)!(n+3)*(n+2)*(n+1)*n*(n-1)!}{(n-1)!5!}[/tex]

[tex]^{n + 4}C_5 = \frac{(n+4)*(n+3)*(n+2)*(n+1)*n}{5!}[/tex]

[tex]^{n + 4}C_5 = \frac{(n+4)*(n+3)*(n+2)*(n+1)*n}{5*4*3*2*1}[/tex]

[tex]^{n + 4}C_5 = \frac{(n+4)*(n+3)*(n+2)*(n+1)*n}{120}[/tex]

What is the measure of angle q°?

Answers

Answer:

Answer:

C. a reflection across the x-axis followed by a 180° rotation around the origin

Step-by-step explanation:

You can figure out the answer to this problem by going through the steps in your head. You can tell the answer is C because if you flip the quadrilateral ABCD over the x-axis and then imagine rotating it around the origin by 180°, it would end up where A'B'C'D' is. If you can't imagine this, you can go onto a graphing calculator like desmos and do the transformations to see if they work.

The smell of woodsmoke and the pop and hiss of burning wood in a campfire brightens any night out in the woods, in the mountains, or on the beach. But make sure that you control your fire, and not the other way around! Before starting your fire, know the local rules. Each park has its own rules about where and when you can have a campfire. Ask at the visitor center or contact the park before you visit, so you know any relevant rules.LATW25_Illustrations17Select all the correct answers.Look at the photograph and the related text.
