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:

x = 28

Step-by-step explanation:

If y = 252, solve for x

y = 9x

252 = 9x

x = 28

Answer:

The answer is false.

Step-by-step explanation:

Answer:

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

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:

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.

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.

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:

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).

Step-by-step explanation:

Answer:

245.84

Step-by-step explanation:

Answer: 600

Step-by-step explanation:

First, let's define our variables for this problem:

D = # of points that Dan scored.

E = # of points that Eric scored.

F = #of points that Frank scored.

We know that:

"Dan scored 6/10 of the points that the three boys scored."

D = (6/10)*(D + E + F)

"Eric scored 7/10 of the remaining"

In this case, the remaining refers to  (1 - (6/10))*(D + E + F) = (4/10)(D + E + F)

Then:

E = (7/10)*(4/10)*(D + E + F)

And we also know that:

F = 120

Then we have a system of 3 equations:

D = (6/10)*(D + E + F)

E = (7/10)*(4/10)*(D + E + F) = (28/100)*(D + E + F)

F = 120

To solve this, the first step is try to reduce the number of variables, then we can just replace the 3rd equation into the other two:

D = (6/10)*(D + E + 120)

E = (28/100)*(D + E + 120)

Now let's try to isolate the variable E in the second equation:

E = (28/100)*D + (28/100)*E + 36.6

E - (28/100)*E = (28/100)*D + 36.6

E( 1 - 28/100) = (28/100)*D + 36.6

E*(72/100) = (28/100)*D + 36.6

E = (100/72)*((28/100)*D + 36.6) = (28/72)*D + 46.666...

Now let's replace this in the other equation:

D = (6/10)*(D + 120 + (28/72)*D + 46.666...)

Let's solve this for D.

D = (6/10)*(D*(100/72) + 166.666)  = 100 + D*(47/72)*(6/10)

D -  D*(100/72)*(6/10) = 100

D*(1- (100/72)*(6/10) ) = 100

D = 100/((1- (100/72)*(6/10) ) = 600

Step-by-step explanation:

Answer:

So If it is a decimal it is .03 and if it is a fraction 3/100

Step-by-step explanation:

So when it's asking you to find the hundredths you place your decimal point to the left 2 places and when you have a fraction you place the hundred over the number.

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]
