A rug has an area of 28 square feet and is 4 feet wide. What is the perimiter of the rug?

Answer:

Question 3: There are 12 boys in the class.

Question 4: 120 cookies were not oatmeal raisin.

Question 5: Target offers the best deal.

Step-by-step explanation:

If the ratio of girls to boys is 3:2, and there are 18 girls, that means there will be [tex]\frac{18}{3}[/tex] * 2 = 6 * 2 = 12 boys.

Because there are 200 cookies total, and [tex]\frac{2}{5}[/tex] of them are oatmeal raisin, that means that [tex]\frac{3}{5}[/tex] of the cookies aren't oatmeal raisin. 200 * [tex]\frac{3}{5}[/tex] = 40 * 3 = 120 cookies that aren't oatmeal raisin.

The cookies at Kroger have a unit rate of $0.45 per cookie, the cookies at Meijer have a unit rate of $0.50 per cookie, the cookies at Walmart have a unit rate of $0.38 per cookie, and the cookies at Target have a unit rate of $0.20 per cookie. So Target has the better buy.

Answer:

a

Step-by-step explanation:

Answer:

a = 9

Step-by-step explanation:

For solve the problem we can use the Pythagorean theorem in this way

a^2 + (3√3)^2 = (6√3)^2

If we solve the equation we have

a^2 + 27 = 108

a^2 = 81

a = +/-9

we take only the the positive value because a length can’t be negative

a = 9

Answer:

The missing measure of the arc is 125°.

Step-by-step explanation:

Since the circle is 360°, you would first subtract 360 by the degrees given: 360-115-35-85 and the sum is 125. Then, you would set 125 equal to -32x-3 to solve for x.

[tex]125=-32x-3[/tex]

[tex]+3[/tex]               [tex]+3[/tex]

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

[tex]\frac{128}{-32} =\frac{-32x}{-32}[/tex]

[tex]x=-4[/tex]

The missing measure of the arc is 125°.

Hi there!

[tex]\large\boxed{\text{Center: (7,2); radius =} \sqrt{10}}}[/tex]

We know that the standard form of the graph of a circle is:

(x - h)² + (y - k)² = r²

Where:

h = x-coordinate of center

k = y-coordinate of center

r = radius

We can identify the following from the given equation:

(x - 7)² ⇒ h = 7

(y - 2)² ⇒ k = 2

r² = 10 ⇒ r = √10

Thus, the correct answer is C.

Step-by-step explanation: Multiply Steve’s hourly wage ($7.40) by the hours he worked in a week (16 Hours) that would give you your weekly earnings which would be (7.40x16=$118.40) Then subtract what he saved in the bank from your total (118.40-105=$13.40) then you would divide $13.40 (his leftover money) by $0.75 to find the total number of carnival rides he could ride (13.40/0.75=17.86 rides and because he cannot ride 17 and 86 hundredths of a ride he would be able to ride 17 carnival rides.

Answer: 1/9 pizza portions

Step-by-step explanation:

The pizza was left with only 1/3 of it and 3 people shared this.

The fractional part of the whole pizza that each of the three people ate is therefore:

= Percentage of who pizza left / Number of people

= 1/3 ÷ 3

= 1/3 * 1/3

= 1/9 pizza portions

Answer:

y = [tex]\frac{1}{3}[/tex] x² - 2x - 2

Step-by-step explanation:

x-coordinate of the vertex of a parabola is ( [tex]- \frac{b}{2a}[/tex] )

y = f(x) = ax² + bx + c

(x, y) ∈ f(x)

~~~~~~~~~

{ (0, - 2), (3, - 5) } ⊂ { (x, y): y = ax² + bx + c }

a(0)² + b(0) + c = - 2 ⇒ c = - 2

a(3)² + b(3) + ( - 2) = - 5  

9a + 3b - 2 = - 5 ⇒ 3a + b = - 1

[tex]- \frac{b}{2a}[/tex] = 3 ⇒ b = - 6a

[tex]\left \{ {{3a+b=-1} \atop {b=-6a}} \right.[/tex]

3a + ( - 6a) = - 1

a = [tex]\frac{1}{3}[/tex]

b = - 2

y = [tex]\frac{1}{3}[/tex] x² - 2x - 2

The equation of the parabola for the given values is y = x²/3 - 2x - 2.

A parabola is the part of the conic section of which the points are equidistant from a fixed line called as directrix and a fixed point known as focus.

The general equation for the parabola is given as,

y = ax² + bx + c

Where c is the y-intercept.

Substitute c = -2 as per the question to obtain,

y = ax² + bx - 2

At (3,-5) the parabola has minimum value which implies y' = 0 as below,

y' = 2ax + b = 0

Substitute x = 3 to obtain,

2a × 3 + b = 0

=> -6a = b

And, y = -5 at x = 3 which gives,

-5 = 3²a + 3b - 2

=> 9a + 3b = -3

Substitute b = -6a to get,

9a - 18a = -3

=> a = 1/3

Which implies b = -6 × 1/3 = -2

Now, the equation for the parabola becomes as below,

y = x²/3 - 2x - 2

Hence, the required equation of the parabola is obtained as y = x²/3 - 2x - 2.

Answer:

(0, infinity)

Step-by-step explanation:

Keep in mind that the input to the ln function can never be 0 or below.  The coefficient 3 has no effect on the domain.  The domain of the function shown is (0, infinity).

The domain of the function y = 3 log x is x > 0.

Option A is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

y = 3 log x

The domain of the function y = 3 log x can never be less than zero.

So,

The domain is from 0 to ∞.

Thus,

The domain is (0, ∞).
