Fission of 1 kg of element B releases 26 times as much energy as burning 1 kilogram of element A.

A ratio can be defined as a mathematical expression that's used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.

A proportion can be defined as an expression which is typically used to represent (indicate) the equality of two (2) ratios. This ultimately implies that, proportions can be used to establish that two (2) ratios are equivalent and solve for all unknown quantities.

Next, we would determine the ratio of the energy released by elements A and B:

EB : EA = EB/EA

Ratio = 1.3 × 10¹⁰/5.1 × 10⁸

Ratio = 25.49 ≈ 26.0

Therefore, fission of 1 kg of element B releases 26 times as much energy as burning 1 kilogram of element A.

Complete Question:

Use the table to the right to answer the following question.

Compare the energy released by fission of 1 kilogram of element B to that released by burning 1 kilogram of element A.

Energy released by burning 1 kilogram of element A is 5.1 × 10⁸

Energy released by fission of hydrogen in 1 kilogram of element B is 1.3 × 10¹⁰

Fission of 1 kg of element B releases ____ times as much energy as burning 1 kilogram of element A. ​(Round to the nearest whole number as​ needed.)

On simplifying the equation this show that the ratio are equal:

4/5 = 4/5 = 4/5 .

To obtain the comparative ratio, find the LCM of both the consequents of both ratios, divide the LCM with both the consequents and then multiply the numerator and denominator of both ratios with the answer.

The ratio is a relationship between the amounts of two or more things that indicates how much of one is contained in the other. The ratio formula can be used to convert a ratio into a fraction. a:b = a/b is the ratio formula for just about any two quantities, say a and b.

4/5, 8/10, and 12/15

dividing the ration to simplify it:

4/5, 8/10, and 12/15

8/10 = 4/5 on dividing by 2

12/15 = 4/5 on dividing by 3

So,

On simplifying the equation this show that the ratio are equal:

4/5, 8/10, and 12/15

4/5 = 4/5 = 4/5 .

The value of the composite function (f o g)(3) is 1603

The functions are given as

f(x) = 3x² - 7x - 3

g(x) = -4x - 10

Next, calculate (f o g)(x) using

(f o g)(x) = f(g(x))

So, we have

(f o g)(x) = 3(-4x - 10)² - 7(-4x - 10) - 3

Substitute 3 for x.

So, we have

(f o g)(3) = 3(-4 x 3 - 10)² - 7(-4 x 3 - 10) - 3

Evaluate

(f o g)(3) = 1603

Hence, the value of the composite function (f o g)(3) is 1603

The expression which has a negative value according to the number line drawn in the task content where points P and S are as given is; Choice D; P + 1.

It follows from the task content that the expression which has a negative value among the given answer choices is to be identified.

As evident in the number line, the number S is greater than 1, and hence, is a positive number.

Also, the number P is less than -1 and hence, is a negative number.

Since, the task content requires that the expression with negative value be identified, it follows that the required expression is; Choice D.

This follows from the fact that, hypothetically, the value of P is -1.8, hence; P + 1 = -1.8 + 1

= -0.8
