Answer:

  2.2, 2.20, 2.2000, 2.20000, ...

Step-by-step explanation:

Any decimal number with more or fewer trailing zeros will be equivalent. Some are ...

  2.2, 2.20, 2.2000, 2.20000

__

These "equivalents" have the same value, but differing numbers of significant digits. If significant digits are important, the given form is the one you want.

[tex]\tt Step-by-step~explanation:[/tex]

Let’s go through several different solutions.

[tex]\tt Simplified:[/tex]

You can just take away two zeros at the end. You will get 2.2.

[tex]\tt Fractions:[/tex]

0.2 is equal to 2/10 or 1/5, so another solution would be 2 1/5.

You can also multiply 5 by 2 and add 1 to get another solution: 11/5.

[tex]\Large\boxed{\tt Our~final~answers:\underline{2.2},~2\frac{1}{5},~\frac{11}{5} }[/tex]

*Underlined: What you needed: decimal

Given:

The point is (-6,5).

It is on the terminal side of theta.

To find:

The values of [tex]\sin\theta[/tex] and [tex]\cos \theta[/tex].

Solution:

In the point (-6,5),

x-coordinate : x=-6

y-coordinate : y=5

So, [tex]r=\sqrt{x^2+y^2}[/tex]

[tex]r=\sqrt{(-6)^2+(5)^2}[/tex]

[tex]r=\sqrt{36+25}[/tex]

[tex]r=\sqrt{61}[/tex]

Now,

[tex]\sin \theta=\dfrac{y}{r}[/tex]

[tex]\sin \theta=\dfrac{5}{\sqrt{61}}[/tex]

[tex]\cos \theta=\dfrac{x}{r}[/tex]

[tex]\cos \theta=\dfrac{-6}{\sqrt{61}}[/tex]

Therefore, the required values are [tex]\sin \theta=\dfrac{5}{\sqrt{61}}[/tex] and [tex]\cos \theta=-\dfrac{6}{\sqrt{61}}[/tex].

Answer:

5 1/4 pounds can be purchased for $12 dollars

Step-by-step explanation:

$6 x 2 = $12

So:

2 5/8 x 2 = ?

21/8 x 2/1 = 48/8 = 5 1/4

Answer:

The sum of any set of consecutive odd numbers starting with 1 is always equal to the square of the number of digits that were added together. Sum of first two odd numbers = 1 + 3 = 4 (= 2 x 2). Sum of first three odd numbers = 1 + 3 + 5 = 9 (= 3 x 3). Sum of first four odd numbers = 1 + 3 + 5 + 7 = 16 (= 4 x 4).

x <−22

Step-by-step explanation:

Let's solve your inequality step-by-step.

−2x+5>49

Step 1: Subtract 5 from both sides.

−2x+5−5>49−5

−2x>44

Step 2: Divide both sides by -2.

2x/ -2 > 44/ -2

Answer:

48 cm^2

Step-by-step explanation:

We can substitute the h in the given equation with 8.

1/2 * (8+4) * 8

Next we can add inside the parenthesis

1/2* (12) * 8

Another way we can write 1/2* 12 is 12 divided by 2 which is equivalent to 6.

So, now our equation is 6*8

6*8 = 48 so our answer is 48 cm^2

Hope this Helps!!! :)

Answer:

[tex]r = 2[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (0,3)[/tex]

[tex](x_2,y_2) = (5,96)[/tex]

Required

Determine the common ratio

An exponential function is of the form.

[tex]y(x) = ar^x[/tex]

For:

[tex](x_1,y_1) = (0,3)[/tex]

We have:

[tex]3 = a * r^0[/tex]

[tex]3 = a * 1[/tex]

[tex]a= 3[/tex]

For

[tex](x_2,y_2) = (5,96)[/tex]

We have:

[tex]96 = ar^5[/tex]

Substitute 3 for a

[tex]96 = 3 * r^5[/tex]

Divide both sides by 3

[tex]\frac{96}{3} = \frac{3 * r^5}{3}[/tex]

[tex]32 = r^5[/tex]

Express 32 as an exponent of 2

[tex]2^5 = r^5[/tex]

By comparison

[tex]2 = r[/tex]

[tex]r = 2[/tex]

Answer: 40%

Step-by-step explanation:

The shaded area represents 4/10 if you multiply the top and bottom by 10 you should get 40/100 which gives you 40% since percents are on a scale from 1 to 100.

Answer:

y=-3/2x+745

Step-by-step explanation:

so u you convert standard form to slope intercept which would be y=-3/2x+745  the y intercept is 745 and the slope (rise over run is the -3/2).

Answer:

1. slope intercept form is y=mx+b, where m is the slope and b is y-intercept. To write this in slope intercept form we must isolate the y. 

2x+3y=1470

2x+3y-2x=1470-2x( subtraction will cancel the positive 2x on the left side)

3y=-2x+1470 ( since they are not like terms we can not combine them, we leave them separate)

3y/3=-2/3x+1470/3( cancel the 3 by dividing, EVERYTHING IN THE EQUATION gets divided to keep it equal) 

So, y=2/3x+490 in other words the slope of the equation is -2/3 and the y-intercept is 490.

2. To graph this equation plot 490 on the y-axis first, seeing it is the y-intercept. Then count over to the right 3 and down 2, to find your next point and do this for every other point. 

.3. In function notation this would look like this : f(x)=-2/3x+490. This function shows how the profit on wrap specials has changed as the number of sandwich specials sold increases

5. The next month Sals profit increased. The function changes because the y-intercept changes. The slope will stay the same.

Step-by-step explanation:

7x − 3 = 25

Add 3 to both sides.

7x = 28

Divide both sides by 7.

x = 4

Answer:

I think is add 3 from both sides

Step-by-step explanation:

7x-3=25

25+3=28

7x=28

x=4

Answer:

The value is  [tex]\sigma = 4.35[/tex]

Step-by-step explanation:

From the question we are told that

  The number of light bulbs produce every hour is  n  =  1409

   The proportion of light bulbs that are defective is  [tex]p = 0.0136[/tex]

Generally from the question we are told to use binomial distribution hence the standard deviation of the number of defective bulbs produced in an hour is  mathematically represented as

        [tex]\sigma = \sqrt{n * p * (1- p )}[/tex]

=>     [tex]\sigma = \sqrt{1409 * 0.0136 * (1 - 0.0136 )}[/tex]

=>     [tex]\sigma = 4.35[/tex]

Answer: it would be c on the test if your not on the test i dont know what it would bb ;]

Step-by-step explanation:

A ratio is a way of comparing two or more similar quantities. Ratios can be used to compare

costs, weights, sizes and other quantities.

For example, suppose we have a model boat which is 1 m long, whereas the actual boat is 25 m

long. Then the ratio of the length of the model to the length of the actual boat is 1 to 25. This

is written as

1 : 25 .

Note there are no units included, and note also the use of the colon to represent the ratio.

Ratios are also used to describe quantities of different ingredients in mixtures. Pharmacists

making up medicines, manufacturers making biscuits and builders making cement all need to make

mixtures using ingredients in the correct ratio. If they don’t there may be dire consequences!

So knowing about ratios is not only very important, but extremely useful and crucial in certain

circumstances.

For example, mortar for building a brick wall is made by using 2 parts of cement to 7 parts o
