3 1/2x + 215 =495 how do you get 80 as x

Answers

Answer 1

Answer:

3 1/2x + 215=495

495-215=280

3 1/2 ÷280

x=80

if this helps

Answer 2

Answer + explanation:

[tex]3\frac{1}{2} x +215=495[/tex]

Minus 215 on both sides

[tex]3\frac{1}{2}x = 280[/tex]

Divide both sides by [tex]3\frac{1}{2}[/tex] to isolate x

280/3.5 = 80

x = 80

Hope this helps :)

Answers

The difference in price per passenger for a group of 16 versus a group of 10 is $26.25.

Given

A group of friends chartered a deep-sea fishing boat out of Destin, FL.

The graph below represents the total cost, in dollars, of the trip as a function of the number of people going.

The group is trying to determine what the price difference would be per passenger if 10 of them go on the trip versus if 16 of them go on the trip.

What is a linear equation?

An equation between two variables that gives a straight line when plotted on a graph.

The group of 16 people would cost $2,500, so it would be $156.25 for each person.

The group of 10 people would cost 1,300 (I got this from going to 10 on the chart then following it up to the line), so it would be $130 per person.

Then, $156.25 - $130 = $26.25

Hence, the difference in price per passenger for a group of 16 versus a group of 10 is $26.25.

what percentage of 205 is 54? can you also show your work

Answers

Answer:

the exact percentage is 26.34146. but i'd write it down as 26.34 or just 26

Step-by-step explanation:

we convert 54/205 into a percentage

Answer:

x = 26.34%

Step-by-step explanation:

Let the percentage be x:

205 * x% = 54

x% = 54 ÷ 205

x% = [tex]\frac{54}{205}[/tex]

[tex]\frac{x}{100}[/tex] = [tex]\frac{54}{205}[/tex]

x = [tex]\frac{54*100}{205}[/tex]

x = [tex]\frac{5400}{205}[/tex]

x = 26.34146341%

x = 26.34%

Please do and explain numbers 2, 4, 6, and 8, thank you.​

Answers

Answer:

2. w = -3

4. c = -2

6. r = 7

8. n = 4

Step-by-step explanation:

It's hard to read the photo, but I'll try.

2.

[tex] 2^{w + 4} \times 2^{4w + 6} = 2^{2w + 1} [/tex]

On the left side, you have a product of 2 powers with the same base.

Give the same base and add the exponents, as in the rule

[tex] a^m \times a^n = a^{m + n} [/tex]

You get on the left side 2 to the sum of the exponents.

[tex] 2^{w + 4 + 4w + 6} = 2^{2w + 1} [/tex]

Simplify the long exponent on the left side.

[tex] 2^{5w + 10} = 2^{2w + 1} [/tex]

Now we have another rule we can use. If two powers are equal, and their bases are equal, then the exponents must be equal.

Here, 2 to the power 5w + 10 equals 2 to the power 2w + 1. Since both bases are 2 and are equal, then the exponents must be equal.

5w + 10 = 2w + 1

Subtract 2w from both sides. Subtract 10 from both sides.

3w = -9

Divide both sides by 3.

w = -3

4.

[tex] \dfrac{1}{5} = 5^{2c + 3} [/tex]

We need to write the left side as a power of 5. Then we equate the exponents like we did in problem 2.

Recall the rule:

[tex] a^{-n} = \dfrac{1}{n} [/tex]

Apply this rule to the left side in reverse.

[tex] 5^{-1} = 5^{2c + 3} [/tex]

Now we have two powers that are equal, both having the same base, 5, so the exponents must be equal.

2c + 3 = -1

2c = -4

c = -2

6.

[tex] 216 = 6^{2r - 11} [/tex]

This is the same idea as problem 4. Write the left side as a power of 6.

[tex] 6^3 = 6^{2r - 11} [/tex]

[tex] 2r - 11 = 3 [/tex]

[tex] 2r = 14 [/tex]

[tex] r = 7 [/tex]

r = 7

8.

[tex] 4^{n} \times 4^{2n - 9} = 64 [/tex]

This problem is similar to problem 2.

[tex] 4^{n + 2n - 9} = 4^3 [/tex]

[tex] 4^{3n - 9} = 4^3 [/tex]

3n - 9 = 3

3n = 12

n = 4

7) When Ernest Rutherford worked with radioactive decay of radium, he noticed it had a
half-life of 100 days. This means that whatever the amount of radium he has at the
beginning, in 100 days he'll have half of that amount. In one experiment, he starts with
320 mg of radium, and stores it for 40 days. How much radium will be left after the 40
days?

Answers

Using an exponential function, it is found that 242.5 mg of radium will be left after the 40 days.

What is an exponential function?

The exponential function for the amount of a decaying substance is modeled by:

[tex]A(t) = A(0)e^{-kt}[/tex]

In which:

A(0) is the initial amount.k is the decay rate, as a decimal.

In this problem, the half-life is of 100 days, hence:

[tex]A(100) = 0.5A(0)[/tex]

Which is used to find k.

[tex]A(t) = A(0)e^{-kt}[/tex]

[tex]0.5A(0) = A(0)e^{-100k}[/tex]

[tex]e^{-100k} = 0.5[/tex]

[tex]\ln{e^{-100k}} = \ln{0.5}[/tex]

[tex]-100k = \ln{0.5}[/tex]

[tex]k = -\frac{\ln{0.5}}{100}[/tex]

[tex]k = 0.0069314718[/tex]

Then, the equation is:

[tex]A(t) = A(0)e^{-0.0069314718t}[/tex]

He started with 320 mg of radium, hence [tex]A(0) = 320[/tex], and the equation is:

[tex]A(t) = 320e^{-0.0069314718t}[/tex]

After 40 days, the amount left is:

[tex]A(40) = 320e^{-0.0069314718(40)} = 242.5[/tex]

242.5 mg of radium will be left after the 40 days.

Using integrals, it is found that the area bounded by the two curves in the interval is of 550 units squared.

How is the area under a graph found?The area under the graph of a curve bounded above by a function f(x) and below by a function g(x) over an interval [a,b] is given by:

[tex]A = \int_a^b f(x) - g(x) dx[/tex]

In this problem:

The functions are [tex]f(x) = 11x - 3, g(x) = 10x - 5[/tex].The interval is [12, 34], hence [tex]a = 12, b = 34[/tex].

Then:

[tex]A = \int_{12}^{34} 11x - 3 - (10x - 5) dx[/tex]

[tex]A = \int_{12}^{34} x + 2 dx[/tex]

[tex]A = \frac{x^2}{2} + 2x|_{x = 12}^{x = 34}[/tex]

Applying the Fundamental Theorem of Calculus:

[tex]A = \frac{34^2}{2} + 2(34) - \frac{12^2}{2} - 2(12) = 550[/tex]
