(2.54 × \(10^{19}\)) + (3.218 × \(10^{17}\)

= 2.57218 × \(10^{19}\)

Hope this was helpful for you!!

The sum of 2.54 x 10¹⁹ and 3.218 x 10¹⁷ will be 2.57218 x 10¹⁹ so option (D) will be correct.

A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation. There could be only two terms, but there could be one hundred, thousand, or a million. There are summations with an infinite set of parameters.

In another word, the summation is to add or subtract any two or more terms by doing that operation we will get a new result which could be big or small depending upon the number.

Given the digits are

2.54 x 10¹⁹ and 3.218 x 10¹⁷

Now in order to sum we need to make an equal exponent of 10

So,

2.54 x 10¹⁹ = 254 x 10¹⁷

Now, Summation

254 x 10¹⁷  + 3.218 x 10¹⁷

257.218 x 10¹⁷ = 2.57218 x 10¹⁹

Hence "The sum of 2.54 x 10¹⁹ and 3.218 x 10¹⁷ will be 2.57218 x 10¹⁹ so option (D) will be correct".

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

Answer:

For A: The first function has a greater ROC

For B: The first function has a negative slope

Step-by-step explanation:

Explication for A:

We already know that the R.O.C. (slope) is 2 for the first function, so all we need to do is substitute the values in the table into the following formula: y2-y1/x2-x1

after substituting: (-3-(-6))/(0-(-1))

simplify 3/1=3, since the ROC is 3, the second equation has a greater ROC than the first

Explanation for B:

The first function described is f(x)=20-3.5x

This is because the y intercept is the starting point, or how much money she has in the gift card. She spends 3.5 dollars per week, so we add a variable to represent the number of weeks, and its negative since she is spending, not earning. We also know that the slope is negative since y is decreasing as x is increasing, on the table.

The second function described is c(m)=5x+10

This is because the equation represents the total cost of renting a calculator, so both terms are positive.

Answer:

Step-by-step explanation:

To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.

Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.

The sum of the parts in the ratio is 8x + 5x + 2x = 15x.

We know that the total number of fruits is 120. Therefore, we can set up the following equation:

15x = 120

To solve for x, we divide both sides of the equation by 15:

x = 120 / 15

x = 8

Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:

Number of bananas = 2x = 2 * 8 = 16

So, there are 16 bananas in total.

We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Answer:

A number line is used in the mathematical positioning of real numbers that include the numbers from positive infinity to negative infinity. This includes rational, irrational, fractions, and whole numbers. In this case, we are given with an expression that we have to reduce to lowest terms: negative seven and one over two and +1. The first one is equal to -7.5 while the other one is equal to +1. Positive numbers lie on the right side of zero (center of the line) while negative numbers lie on the left on the other hand. -7.5 lies between -8 and -7 while +1 lies exactly between 0 and 2. Both of which are positive numbers

Answer:

p = 12.20h

30.5 hours

Step-by-step explanation:

Jackson works as a veterinary technician and earns per hour = $12.2

He works in a normal week = 40 hours

Let hours = h and weekly pay = p

p = 12.20h

p = $12.20 × 40

= $488.00

Last week Jackson was ill and missed some work.

 His total pay before deduction was $372.10

To find the hours he work the equation will be p = 12.20h

372.10 = 12.20h

372.10/12.20 = h

h= 30.5

Answer:

Therefore, the residents of Somerville used their cell phones for approximately 8,930 minutes last year.

Step-by-step explanation:

To find out how many minutes the residents of Somerville used their cell phones last year, we can use the information given that this year's cell phone usage is 30% more than last year's.

Let's assume the cell phone usage last year was represented by the variable "x" (in minutes).

According to the information given, this year's cell phone usage is 30% more than last year's, so we can express this as:

x + 0.3x = 11609

Combining like terms, we have:

1.3x = 11609

To isolate the variable, we divide both sides of the equation by 1.3:

x = 11609 / 1.3

Simplifying the calculation, we find:

x ≈ 8930

Answer:

walnuts cost $2.50 per pound, chocolate chips cost $1.50 per pound

Step-by-step explanation:

let w be the cost of 1 pound of walnuts

and c be the cost of 1 pound of chocolate chips

then

2w + 12c = 23 → (1)

5w + 3c = 17 → (2)

multiplying (2) by - 4 and adding to (1) will eliminate c

- 20w - 12c = - 68 → (3)

add (1) and (3) term by term to eliminate c

(2w - 20w) + (12c - 12c) = 23 - 68

- 18w + 0 = - 45

- 18w = - 45 ( divide both sides by - 18 )

w = 2.5

substitute w = 2.5 into either of the 2 equations and solve for c

substituting into (1)

2(2.5) + 12c = 23

5 + 12c = 23 ( subtract 5 from both sides )

12c = 18 ( divide both sides by 12 )

c = 1.5

then

cost of 1 pound of walnuts is $2.50

cost of 1 pound of chocolate chips is $1.50

Answer:

\(y - 100 = \boxed{\:-\dfrac{25}{2} \:} \;\;\left(x -\boxed{\:4\:}\:\right)\)

Step-by-step explanation:

The first thing to observe is that the balance declines at a linear rate with respect to time in weeks

The given equation which you have to fill in is in the point-slope form of a straight line

The point slope equation of a straight line is
y - y1 = m(x - x1)

where (x1, y1) is a point on the line
m is the slope = (x2 - x1)/(y2 - y1) with (x1, y1) and (x2, y2) being two points on the line

To find the slope,

Let's take two points say 4, 100) and (8,50) where the first entry is the weeks and second is the current balance

Slope m = (50 - 100)/(8 - 4) = - 50/4 = -25/2

The negative value simply indicates that the balance is declining by 25/2 every two weeks

Having got the slope we can rewrite the equation as

y - y1 = -25/2(x - x1)

Again take (x1, y1) as (4, 100) to get

\(y - 100 = \boxed{-\dfrac{25}{2}} (x -\boxed{ 4})\)

And this is the answer

Answer:

1. slope = 12

  y-intercept = 1/3

2.slope = 1/4

  y-intercept= -12

3.slope = 3

  y-intercept = 2

Step-by-step explanation:

When you get an equation for a graph, the co-efficient infront of the x (The number by the x) is the slope.

The equation for the y-intercept:

When solving for y-intercept, you replace y in the equation with 0 and make x the subject.

Example:
y = 12x - 4

0=12x - 4

-12x = -4

divide both sides by negative 12 since we want only positive x

\(\frac{-12x}{-12} =\frac{-4}{-12}\)

x = \(\frac{1}{3}\)

Therefore, the y-intercept = 1/3
