60 increase 3% =

60 × (1 + 3%) = 60 × (1 + 0.03) = 61.8

Answer:

Sales tax:1.80 total cost:61.80

Step-by-step explanation:

Price x sales tax rate = sales tax

60 x .03=1.80

price + sales tax = total cost

60 + 1.80=61.80

Answer:

v < 9

Step-by-step explanation:

Since the value of the hat is less than 9, we will use a less than sign.

In the inequality, the less than sign has to be in front of 9.

So, put this together:

v < 9

The inequality is v < 9

Answer:

t=-4

Step-by-step explanation:

48/-12

Answer:

48=-12t

We simplify the equation to the form, which is simple to understand  

48=-12t

We move all terms containing t to the left and all other terms to the right.  

+12t=-48

We simplify left and right side of the equation.  

+12t=-48

We divide both sides of the equation by 012 to get t.  

t=-4

Answer:

times 2075 by .30 and that's your answer

The total retail cost of all the jewelry is $2697.5

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

Maybell just purchased $2075 worth of jewelry.

Now, marks up her cost by 30% then

= 2075 x 30/100

= 622.5

Thus, the total retail cost of all the jewelry

= 2075+ 622.5

= $2697.5

Step-by-step explanation:

Answer:

[tex]\displaystyle \sin(\theta)= \frac{\sqrt{17}}{17}[/tex]

[tex]\displaystyle \cos(\theta)= \frac{4 \sqrt {17} }{ 17 }[/tex]

Step-by-step explanation:

We want to find sin(θ) and cos(θ) given that tan(θ) = 1/4 and sin(θ) > 0.

First, since tan(θ) and sin(θ) are both positive, cos(θ) must be positive as well.

Recall that tangent is the ratio of the opposite side to the adjacent side.

Therefore, the hypotenuse is:

[tex]h=\sqrt{4^2+1^2}=\sqrt{16+1}=\sqrt{17}[/tex]

So, with respect to θ, the opposite side is 1, the adjacent is 4, and the hypotenuse is √17.

Then it follows that:

[tex]\displaystyle \sin(\theta)=\frac{1}{\sqrt{17}} = \frac{\sqrt{17}}{17}[/tex]

And that:

[tex]\displaystyle \cos(\theta)= \frac{4}{\sqrt{17}} = \frac{4 \sqrt {17} }{ 17 }[/tex]

Answer:

65

Step-by-step explanation:

180-115=65

It needs to be a total of 180 so just do what I did :)

Answer:

68%

Step-by-step explanation:

The empirical rule basically states that 68% of the data falls within one standard deviation from the mean, 95% of the data falls within two standard deviations from the mean, and 99.7% of the data falls within three standard deviations from the mean.

So to find the percentage of IQ scores between 70 and 138, you need to find how far each of these numbers is from the mean in terms of the standard deviation.

If you subtract the standard deviation from the mean, you receive 87, and if you add the standard deviation to the mean, you receive 121.

This means that both of these numbers are within one standard deviation from the mean meaning according to the empirical rule, that means 68% of the IQ scores are between 70 and 138.

good luck, i hope this helps :)

Answer:

99.7%

Step-by-step explanation:

According to the empirical rule, approximately 99.7% of data values lie within 3 standard deviations of the mean.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given that:

scores = 2, 3, 4, 4, 5, 5, 5, 6, 6, 7

Since the scores are already in ascending order; then the median which is the middle number will be:

median = (5th term + 6 term)/2

median = (5+5)/2

median = 10/2

meian = 5

PUT THIS INTO YOUR OWN WORDS bc I just put what Edg said :)

Answer:

a) 7.78 months

b) 1116

Step-by-step explanation:

Given -

[tex]\frac{dP}{dt} = 0.4p-450[/tex]

Integrating the above equation with respect to time, we get -

[tex]\int\ \frac{dP}{0.4p-450} = \int\ dt\\[/tex]

let us define new variable x

[tex]x = 0.4p - 450 \\dx = 0.4 dy[/tex]

substituting these values in above integral equation, we get -

[tex]\frac{1}{0.4} \int\ \frac{dx}{x} = \int\ dt\\ln x = 0.4 t + C\\x = ce^{0.4t}[/tex]

[tex]P (t) = \frac{C}{0.4} e^{0.4t} +1125\\[/tex]

at t = 0, P (0) = 1075, using this condition, we get -

[tex]\frac{c}{0.4} = -50\\P(t) = 50 e^{0.4t} +1125 \\t = 7.78\\P(0) = 1125 - \frac{1125}{e^{4.8}} = 1116[/tex]
