Answer:

Ounces of green paint needed = 13.8

Step-by-step explanation:

Blue paint : green paint = 25 : 115

how many ounces of green paint should she mix with 3 ounces of blue paint?

Let

Ounces of green paint needed = x

Blue paint : green paint = 3 : x

Equate both ratios

25 : 115 = 3 : x

25/115 = 3/x

25 * x = 115 * 3

25x = 345

x = 345/25

x = 13.8 ounces

Ounces of green paint needed = 13.8

Answer:

[tex]f(x) = 2x - 4 \\ f(x + 3) = 2(x + 3) - 4 \\ = 2x + 6 - 4 \\ = 2x + 2 \\ = 2(x + 1)[/tex]

Answer:

Ok, let's suppose that the unknown amount is the number of books you buy in a library. (let's represent this unknown quantity with the variable X)

We know that each book costs $9.75, and we know that in total cost for the X books is $68.25

Then, how many books do you get?

We know that if one book costs  $9.75, then X books will cost X times $9.75

Then the total cost is:

C(X) = X* $9.75

And we know that the total cost was $68.25

Then to solve this, we need to solve the equation:

X* $9.75 = $68.25

X = $68.25/$9.75 = 7

The equation that can be used to represent the information is the cost of a book is $3, find the number of books when a customer pays $21.

To represent the scenario, the cost of a book is $3, find the number of books when a customer pays $21.

Therefore, the number of books will be:

3x = 21

x = 21/3

x = 7

In conclusion, the correct option is $7.

Answer:

x = 6.0

Step-by-step explanation:

As the given triangle is a right-angled triangle, we can use the trigonometric ratios to find the required length.

In the given triangle

Hypotenuse = 10

Perpendicular = x

Angle = 37°

As we know the value for perpendicular and hypotenuse, sine will be used.

[tex]sin\ 37 = \frac{Perpendicular}{Hypotenuse}\\sin\ 37 = \frac{x}{10}\\0.6018 = \frac{x}{10}\\x = 0.6018*10\\x = 6.018[/tex]

Rounding off to nearest tenth

x = 6.0

Hence,

x = 6.0

Answer:

x = 111°

Step-by-step explanation:

Angles in a triangle add up to 180

180 - (29+82) = 69

Angles on a straight line add up to 180

180 - 69 = 111

Answer:

111°

Step-by-step explanation:

the sum of the outer angles of a triangle is alway 180

so 180-82-29= 69°

180-69= 111°

Answer:

Answer:

3 sides

Step-by-step explanation:

sum of exterior angles for all polygons is 360°

sum of interior angles for a polygon can be found by using the formula:

(n - 2) · 180°  where 'n' is the number of sides

'sum of outer angles' = 360

'twice the sum of inner angles' = 2n

360 = 2n

n = 180

a three-sided polygon (triangle) has 180 degrees

Answer:

1.) [tex]\sqrt{13.341}[/tex]  ≈ 3.652

2.) I would say something about how the A in front of cos in the equation would change to 90, rather than stay 75 (in the equation for the step by step), but it would be easier to just use the Pythagorean theorem.

Step-by-step explanation:

I think we may have the same class so hopefully this helps:

1.) [tex]a^2 = b^2 + c^2 - 2bccosA[/tex] --> law of cosines formula.

   [tex]a^2 = 3^2 + 3^2 - 2(3)(3)cos(75)[/tex] --> plugged in numbers; when you draw the triangle, the included angle would be A, and the opposite side would be a. B and b, and C and c are opposite each other. In this case, a is the hypotenuse.

   [tex]a^2 = 18 - 18cos75[/tex] --> in between steps.

   [tex]a^2 = 13.341[/tex] --> more simplifying.

   [tex]a(hypotenuse) = \sqrt{13.341} or 3.652[/tex] --> answer

2.) This one is just an explanation: The 75 in the equation is the given angle, which is a. If this changes, it would just change in the equation too. And obviously, if it's 90 degrees, you can just use Pythagorean theorem a^2+b^2=c^2.

Good luck! :)

Answer:

fourth option

Step-by-step explanation:

Using the sine and cosine ratios in the right triangle and exact values

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , cos60° = [tex]\frac{1}{2}[/tex] , then

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{4\sqrt{2} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2x = 4[tex]\sqrt{6}[/tex] ( divide both sides by 2 )

x = 2[tex]\sqrt{6}[/tex]

---------------------------------------------------------

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{y}{4\sqrt{2} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2y = 4[tex]\sqrt{2}[/tex] ( divide both sides by 2 )

y = 2[tex]\sqrt{2}[/tex]

Answer: [tex]5x^2y^5[/tex]

Step-by-step explanation:

Given: Area of rectangle = [tex]35x^4y^{10}[/tex] square feet

Length of rectangle= [tex]7x^2y^5[/tex]

We know that,

Width of rectangle = [tex]\dfrac{\text{Area of rectangle}}{\text{Length}}[/tex]

Then,

Expression of width= [tex]\dfrac{35x^4y^{10}}{7x^2y^5}[/tex]

[tex]=\dfrac{5x^{4-2}y^{10-5}}{1}\ \ \ \ [\frac{x^m}{x^n}=x^{m=n}]\\\\=5x^2y^5[/tex]

Hence, the expression for width of the rectangle = [tex]5x^2y^5[/tex]

Answer:

(1, 0.5)

Step-by-step explanation:

From the graph attached,

x-values are representing the number of games downloaded,

y - values are representing the total cost.

Unit rate means rate of 1 game downloaded.

If we represent this in terms of coordinates,

x- value (game downloaded) = 1

y - value (price of one game download) = $0.5

Therefore, point (1, 0.5) will represent the unit rate.

Option (2) on the top row will be the answer.

Answer:

The probability is 1/10.

Step-by-step explanation:

Without loss of generality, the first card is blue. Then choose a red one with probability 3/5, a blue one with probability 2/4=1/2, a red one with probability 2/3, and the last blue one with probability 1/2, followed by the last red one.

The result is 2/5⋅(1/2)^2=1/10.

OR

There are actually 6!/(3!3!)=720/36=20 ways, so the probability is 2/20=1/10.
