Answer:6.95

6.95= 6.95>6.841

6.8= 6.800<6.841

6.786<6.841

6.839<6.841

Answer:

6.95

Step-by-step explanation:

We can find the answer by analyzing the options and deducing which is greater or less.

That is, if we have the number 6.841, the number 6.95 must be greater because it has 9 intead of an 8, which makes it a bigger number.

We can also make a division between the original number and the number that we want to know if it is greater or less, and if the division is less than 1 it means that the number is greater, and if the division is greater than 1 it means that the number is smaller.

6.841/6.8 = 1.006 ⇒⇒ 6.8 is smaller than 6.841

6.841/6.786 = 1.008 ⇒⇒ 6.786 is smaller than 6.841

6.841/6.839 = 1.0003 ⇒⇒ 6.839 is smaller than 6.841

6.841/6.95= 0.98 ⇒⇒ 6.95 is greater than 6.841

Step-by-step explanation:

[tex] average~rate~of~change = \dfrac{f(x_2) - f(x_1)}{x_2 - x_1} [/tex]

[tex] x_1 = 0 [/tex]

[tex] x_2 = 2 [/tex]

[tex] f(x_1) = f(0) = 0^2 + 7(0) + 10 = 10 [/tex]

[tex] average~rate~of~change = \dfrac{18}{2} [/tex]

[tex] average~rate~of~change = 9 [/tex]

Answer:

9

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

here [ a, b ] = [ 0, 2 ]

f(b) = f(2) = 2² + 7(2) + 10 = 4 + 14 + 10 = 28

f(a) = f(0) = 0 + 0 + 10 = 10, hence

average rate of change = [tex]\frac{28-10}{2-0}[/tex] = [tex]\frac{18}{2}[/tex] = 9

Answer:

(x + 3)(x + 4)

Step-by-step explanation:

To factor the trinomial

Consider the factors of the constant term ( + 12) which sum to give the coefficient of the x- term ( + 7)

The factors are + 3 and + 4, since

3 × 4 = 12 and 3 + 4 = 7, hence

x² + 7x + 12 = (x + 3)(x + 4)

Thus length can be x + 3 or x + 4 and

the width can be x + 4 or x + 3

Answer:

X 2 + 84 / 7 by 12

Answer:

x ≤ -27

Step-by-step explanation:

x/-9 ​≥ 3

well since theres division and we want to separate the x's and the naked numbers by themselves were going to have to multiply

x ≥ 3 x -9

x ≥ - 27  (but since theres a negative the symbol  ≥ is going to switch)

x ≤ -27

TIP: remember we always do the opposite when switching a numbers place for example if we have +9 if we switch it place to the other side its going to become -9, same thing with multiplication and division.

example:

3 + x = 5                          or           3x = 5

x = 5 - 3                                          x = 5/3

~batmans wife dun dun dun...aka ~serenitybella

The solution to the inequality (x/-9) ≥ 3 in fraction form is x ≤ -27.

The relationship between the two values which are either greater or lesser than each other but not equal is called inequality.

The primary application of inequality is to compare two numbers on a number line.

The inequality can be solved as:

(x/-9) ≥ 3

 Multiply both sides of the inequality by -9. The multiplication of a number with a negative sign changes the direction of the inequality.

The equation can be written as:

[tex]\dfrac{-9x}{-9} \leq -9(3)[/tex]

x ≤ -27

Thus, the solution to the inequality (x/-9) ≥ 3  is x ≤ -27.

#SPJ4

Answer:

= 18 cubic inches

Step-by-step explanation:

The volume of a cone is given by the formula;

V = 1/3 × base area × height

While that of cylinder is given by the formula;

Volume = Base area × height

Since we need the cylinder to fit exactly inside the cone, then it  means that their bases are the same and heights are the same.

Therefore;

The cone has three times less volume compared to the cylinder.

Thus;

Volume of the cylinder = Volume of cone × 3

                                       = 6 In³ × 3

                                       = 18 cubic inches

Answer:

ok

Step-by-step explanation:

The value of x, given the equation, can be found to be (5y - 35) / 6.

To find the value of x in the equation 6x = 5y - 35, you need to isolate x.

Start with the equation:

6 x = 5 y - 35

To isolate x, divide both sides of the equation by 6:

( 6 x ) / 6 = ( 5 y - 35 ) / 6

Simplify both sides:

x = ( 5 y - 35 ) / 6

So, the value of x is ( 5 y - 35 ) / 6.

Final answer:

Carla spent two-fifths of her savings on a bracelet and had $9 left. Her original savings were $22.50, so the bracelet cost $9.

Explanation:

Carla spent two-fifths of her savings on a bracelet and had $9 left over. To determine the cost of Carla's bracelet, we need to let s represent her original savings. According to the problem, the remaining savings after purchasing the bracelet is s - (2/5)s = $9.

To solve for the cost of the bracelet, we can set up the equation (2/5)s = s - $9. By multiplying both sides by 5/2 to isolate s, we get:

s = (5/2) * ($9)

s = $22.50

So her original savings were $22.50. This means Carla spent (2/5) * $22.50 on the bracelet. Calculating this gives:

Cost of bracelet = (2/5) * $22.50

Cost of bracelet = $9

Thus, Carla's bracelet cost $9.

Answer:

Step-by-step explanation:

In this type of problem it's reasonable to use a calculator for the computation.  Here, 83.31·6.2 = 516.522.  Double check to ensure that you've copied all of the possible answer choices correctly.

The value of the expression is 516.522, which corresponds to option B.

To solve the expression 83.31 * 6.2, we need to multiply the two numbers. Here is the step-by-step calculation:

Multiply 83.31 by 6.2 without considering the decimal places: 8331 * 62 = 516,522.

Count the total number of decimal places in the factors. In this case, 83.31 has two decimal places, and 6.2 has one, so there are three decimal places in total.

Place the decimal point in the result (516,522) to reflect the combined number of decimal places from the factors: 516.522.

Therefore, the value of the expression 83.31 x 6.2 is 516.522, which corresponds to option B.

Answer:

See below

Step-by-step explanation:

Part A

Formula

M = 2/3 * log(E/Eo)

Givens

M = ??

E = 2 * 10^15 joules

Eo = 10^4.4

Solution

M = (2/3) * log(2 * 10^15 / 10^4.4)

M = (2/3 ) log (7.96 * 10 ^ 11)

M = (2/3) * 11.901

M = 7.934

Part B

What the question is saying is that E/Eo = 10000

You don't have to figure out exact values.

M = 2/3 * log(10000)

M = 2/3 * 4

M = 8/3 or 2 2/3 or 2.66667

If you have choices, please list them.

Answer:

A ; M = 7.267

B ; M = 2.667

Step-by-step explanation:

Formula

M = (2/3) log (E/Eo)

M = 2/3 * log (2 * 10^15/10^(4.4) )

M = 2/3 * log( 7.9621* 10^10)

M = 2/3 * 10.901

M = 7.267 on the Richter scale.

Part B

Suppose that you use Eo and your base. Eo is 10^4.4

Now the new earthquake is E = 10000 * Eo

So what you get now is M = (2/3)* Log(10000 * Eo / Eo )

M = 2/3 * log(10000)

M = 2/3 of 4

M = 8/3

M = 2.6667

What this tells you is that if the original reading was (say) 6 then the 10000 times bigger reading would 8.266667

She needs to save $1,200 in 12 weeks, now divide thow much she needs to save by the number of weeks to find how much she needs to save each week:

1200 / 12 = 100

She needs to save $100 per week.

There are likely approximately 180 defective MP3 players in a shipment of 4,500 units.

The question asks how many MP3 players in a shipment of 4,500 units are likely to be defective given that a random sample of 50 MP3 players found 2 defective ones. To estimate the number of defective players in the entire shipment, we can use proportion. If 2 out of 50 MP3 players are defective, we set up a proportion to estimate the likely number of defectives in the entire 4,500 units.

Assuming the sample is representative of the whole shipment, the proportion would be:

2 (defective in sample) / 50 (sample size) = x (estimated defectives in shipment) / 4,500 (shipment size)

To solve for x, the likely number of defective MP3 players, we cross-multiply and divide:

2 / 50 = x / 4,500
50x = 2 * 4,500
50x = 9,000
x = 9,000 / 50
x = 180

Therefore, using the sample proportion, we would expect there to be approximately 180 defective MP3 players in the shipment.

x=smaller number

y=larger number

x+y=12

y=3x-6

Let's begin with the first equation...

x+y=12

Let's substitute...

x+(3x-6)=12

4x-6=12

Let's add 6 to both sides as we proceed to isolate x...

6+4x-6=12+6

4x=18

Let's divide both sides by 4...

(4x)/4=18/4

x=9/2=4.5---smaller number

12-4.5=7.5s larger number

Answer:

The sum of the two numbers is -18.

Step-by-step explanation:

You can work your way through the problem starting with ...

1/3 the difference of two numbers is 12

Since 3 times 12 is 36, the difference of the two numbers is 36.

Then you are told ...

the larger number is 9

so the smaller number will be 9 less the difference, or ...

smaller number = 9 - 36 = -27.

Now, you know both numbers, so you know there sum is ..

9 + (-27) = -18 . . . . . sum of the two numbers

_____

You can work it also using L for the larger number, D for the difference. Then the smaller number is (L-D) and the sum is ...

sum = L + (L -D) = 2L - D

Filling in the values given for the larger number and the difference, you have ...

sum = 2·9 - 3·12 = 18 -36 = -18 . . . . . as before
