The results after simplifying a linear equation are shown.

Which result shows exactly one solution?

A: x=x

B: x=2

C: 1=1

D: 0=1

Answer:

1. D and C

2. F = 9/5(k-273) + 32

Step-by-step explanation:

1. We simply want to write the given equation in different forms;

PV = nRT

So P = nRT/V

R = PV/nT

V = nRT/P

n = PV/RT

T = PV/nR

So the correct expressions are;

D, C,

2. we want to make F the subject of the formula, that would be;

C = 5/9(F - 32)

9C = 5(F - 32)

divide both sides by 5

9C/5 = F - 32

F = 9C/5 + 32

But K = C + 273

So C = K - 273

Insert this into the equation, we have

F = 9(K-273)/5 + 32

Answer:

180 Miles?

Step-by-step explanation:

First divide 150 by 2 1/2 (or 2.5)

You'll end up with 60

Then times it by the amount of hours (3)

60 x 3 = 180

Answer:

Choice B

Step-by-step explanation:

The area of the triangle is 10 square units, the correct option is B.

A triangle is a polygon with three sides, angles, and vertices.

The triangle is classified into various types on the basis of the angle and on the basis of equality of the length of the sides.

The vertices of the triangle are at:

(-3,3), (2, 3), and (4,7).

The area of the triangle has to be determined.

The length of the sides will be calculated using the distance formula.

side 1 = [tex]\rm \sqrt { (3-3)^2 + ( 2 +3)^2}[/tex] = 5 units

side 2 = 2√5 units

side 3 = √65 units

The height of the triangle is determined by calculating the distance from (4, 7) to (4, 3).

The height of the triangle = 4 units

The area of a triangle is given by,

A = (1/2) * base * height

A = (1/2) * 5 * 4

A = 10 square units

Answer:

The alternative is characterized in the interpretation section following the table, as per the case mentioned.

Step-by-step explanation:

According to the question:

The sample mean will be:

⇒ [tex]\bar{x}=\frac{\Sigma x}{n}[/tex]

      [tex]=\frac{1050500}{55}[/tex]

      [tex]=19100[/tex]

The critical value of z ([tex]z_e=1.96[/tex]) seems to be the 95 % confidence interval. So the required confidence interval will be:

=  [tex]\bar{x} \ \pm \ x_{critical}\frac{\sigma}{\sqrt{n} }[/tex]

= [tex]19100 \ \pm \ 1.96.\frac{3027}{\sqrt{25} }[/tex]

= [tex]19100 \ \pm \ 800[/tex]

The 95% confidence interval is ($18300 , $19900) and according to the confidence interval, the average estimated price of fires results through the use of tobacco is somewhat more costly than that of the average cost of flames results from across all factors that cause.

Given :

First, find the sample mean by using the following formula:

[tex]\rm \bar{x}=\dfrac{\sum x}{n}[/tex]

[tex]\rm \bar{x}=\dfrac{1050500}{55}[/tex]

[tex]\rm \bar {x} = 19100[/tex]

Now, for 95% confidence level, the confidence interval will be:

[tex]= \rm \bar{x} \pm x_{critical} \dfrac{\sigma}{\sqrt{n} }[/tex]

[tex]\rm = 19100\pm 1.96\times \dfrac{3027}{\sqrt{55} }[/tex]

[tex]=19100\pm 800[/tex]

The 95% confidence interval is ($18300 , $19900).

According to the confidence interval, the average estimated price of fires results through the use of tobacco is somewhat more costly than that of the average cost of flames results from across all factors that cause.

Answer:

x(4 × 2) + x(3 × 4)

Step-by-step explanation:

The question says "which of the following equations" which infers you have already been given options. However, none were provided in the question so my answer may be slightly different than the given options as there's several ways to solve this problem.

Monday through Thursday = 4 days × 2 hours per day

Friday through Sunday = 3 days × 4 hours per day

To find the total for one week, add the two expressions together:

(4 × 2) + (3 × 4)

The question states for "x weeks" so:

x(4 × 2) + x(3 × 4)

This is one way the equation can be written

Another way is:

x[(4 × 2) + (3 × 4)]

Answer:

0.1

Step-by-step explanation:

multiply 0.01 by 10 and then you get the answer

The number is 0.1.

A fraction is a part of a whole. In arithmetic, the number is expressed as a quotient, in which the numerator is divided by the denominator.

given:

0.01 is 1/10

let the number be x

x of 1/10 = 0.01

x* 1/10= 0.01

x= 0.01*10

x=0.1

Step-by-step explanation:

the y intercept is the point where the line crosses the y-axis. given this info, its given that the y intercept would be 5, or (0,5) in coordinates ^_^

Answer:

0,5

Step-by-step explanation:

So this is actually simpler than it looks. All you have to do is see what point starts out with the x coordinate at zero. The center of the graph is 0,0, so the y intercept is 0,5 because that is the first graph of y.  The order is 0,5 1,6 2,7 so on and so on. Hope my explanation made sense.

Answer:

Scale factor = [tex] \frac{5}{4} = 1\frac{1}{4} [/tex]

Step-by-step explanation:

The scale factor is how much the right triangle on the right was increased in size or enlarged, since the right triangle is a scaled copy of the one on the left.

The scale factor used = the ratio of any of their corresponding sides

Scale factor = side length of the ∆ on the right ÷ corresponding side length of the ∆ on the left

Scale factor = [tex] \frac{15}{12} [/tex]

Scale factor = [tex] \frac{5}{4} = 1\frac{1}{4} [/tex]

The scale factor expressed as a fraction is 4/5

Since the right triangle on the right is a scaled copy of the right triangle on the left, then the ratio of their similar sides is equal to the scale factor.

This is expressed as:

Taking the ratio of the fractions

[tex]\frac{20}{25} = \frac{4}{5}[/tex]

Similarly for [tex]\frac{12}{15}[/tex]

[tex]\frac{12}{15} =\frac{4}{5}[/tex]

This shows that [tex]\frac{20}{25} = \frac{12}{15} = \frac{4}{5}[/tex]

Hence the scale factor expressed as a fraction is 4/5
