Step-by-step explanation:

so to do this your gonna
50 + 18 = 68$
then you just add 18 till you reach as close as you can get to 160$
68$+18$=86+18=104+18=122+18=140+18=158$
then you count the 18's
there is 6 18's witch means that Luis is can kayak for a max of 6 hours

The maximum number of hours Luis can rent the kayak gven the amount he can spend is 6 hours.

The equation that represents the total amount of money he can spend is:

$160 = $50 + $18h

Where h represents the number of hours

In order to determine the value of h, take the following steps:

Combine similar terms

$160 - $50 = 18h

Add similar terms

$110 = 18h

Divide both sides by 18

h = 6 hours

to get the equation of any straight line we simply need two points off of it, hmm let's get two from this table

[tex](\stackrel{x_1}{1}~,~\stackrel{y_1}{10})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{22}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{22}-\stackrel{y1}{10}}}{\underset{run} {\underset{x_2}{3}-\underset{x_1}{1}}}\implies \cfrac{12}{2}\implies 6 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{10}=\stackrel{m}{6}(x-\stackrel{x_1}{1}) \\\\\\ y-10=6x-6\implies y=6x+4[/tex]

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000368

mm, while the length of the second strain measures 0.000000064 mm. How much larger is the first strain than the second?

We can figure this out using scientific notation.

[tex]0.000000368 - 0.000000064[/tex]

[tex]= 3.04e-7[/tex]

Put 3.04e-7 in standard notation.

[tex]0.00000304[/tex]

Put 0.00000304 back into scientific notation, instead with a multiply sign.

Move the dot back, making the number in between 1-10.

In this case, we would move it back 7 times.

Since a regular polygon has equal interior angles, then the measure of the angle marked x is: 132°.

A regular polygon is any n-sided polygon that has equal interior angles and equal sides.

Thus:

Therefore:

x = 360 - 120 - 108

x = 132°

Thus, since a regular polygon has equal interior angles, then the measure of the angle marked x is: 132°.

Answer:

x = 30°

Step-by-step explanation:

84° + 66° + x = 180°

150° + x = 180°

x = 180° - 150°

x = 30°

Answer:

The value of x is 30°

Step-by-step explanation:

The sum of angles of a triangle is equal to 180°

so, x°+66°+84° = 180°

=> x° + 150° = 180°

=> x° = 180°-150°

=> x = 30°

Answer:

The answer is C.9

Step-by-step explanation:

in order to fine the mean using number data you need to add all the number then divide by that much numbers. So for example 10+12+11+10+7+6+7 would equal 63. So since you have 7 numbers of data, you need to divide 7 and 63 (7÷63). 7÷63 equals 9. So therefore the answer is C.9.

The logarithmic function is the inverse of the exponential function. The logarithmic function that is equivalent to 2⁵ = 32 is log₂32=5.

A log function is a way to find how much a number must be raised in order to get the desired number.

[tex]\rm a^c=b[/tex] can be written as [tex]\rm log_ab=c[/tex].

where a is the base to which the power is to be raised,

b is the desired number that we want when power is to be raised,

c is the power that must be raised to a to get b.

Given to us

2⁵ = 32

As we know that we can convert a number powered to another number therefore exponential function into a log function, thus,

[tex]\rm 2^5=32\\\\log_25=5[/tex]

Hence, The logarithmic function is the inverse of the exponential function. The logarithmic function that is equivalent to 2⁵ = 32 is log₂32=5.

The probability that a point is not on AB is the probability that a point is on BC

The probability that a point is not on AB or CD is 5/14

From the figure, we have the following parameters:

AD = 28

AB = 12

BC = 10

CD = 6

if a point is not on AB or CD, then the point would be on BC

This means that we calculate the probability that a point is on BC

So, we have:

P(BC) = BC/AD

This gives

P(BC) = 10/28

Simplify

P(BC) = 5/14

Hence, the probability that a point is not on AB or CD is 5/14

If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:

[tex]CI = P(1 +\dfrac{R}{100})^T - P[/tex]

The final amount becomes:

[tex]A = CI + P\\A = P(1 +\dfrac{R}{100})^T[/tex]

If the initial amount (also called as principal amount) is P, and the interest rate is R% annually, and it is left for T years for that simple interest, then the interest amount earned is given by:

[tex]I = \dfrac{P \times R \times T}{100}[/tex]

For the considered case, we're given that:

In first account, the final amount at the end of 5 years is evaluated as:

[tex]A = 24000(1 + \dfrac{2.4}{100})^4 = 24000(1.024)^4 \approx 27021.59\: \rm (in \: dollars)[/tex]

In second account,  the final amount at the end of 5 years is evaluated as:

Total amount after 5 years in these accounts = [tex]27021.59 + 26880 = 53901.59[/tex] (in dollars)
