Answer:

There is an average of approximately 1 sheep per square mile.

Step-by-step explanation:

Given there are 9.54 sheep spread across 18.52 square miles of land.

The average number of sheep per square mile is given as

A = 9.54/18.52

Without using a calculator, this is by inspection, about 9/18 = 0.5.

Using a calculator, we have

A = 9.54/18.52 = 0.51511879

Approximately 1 sheep per square mile.

Answer:

84 pounds per square inch

Step-by-step explanation:

 Extracting the key information from the question:

*** Volume of a gas is inversely proportional to pressure of the gas.

*** A balloon is filled with  228 cubic inches of a gas at a pressure of 14 pounds per square inch.

*** Volume is then decreased to 38 cubic inches. we are required to find the new pressure of the gas.

    Since volume is inversely proportional to pressure, then:

     V = k × (1/p)

      V = k/p

V = volume, p= pressure, k = mathematical constant

Since, V = 228 cubic inches, P = 14 pounds per square inches, k = ?

 Substituting appropriately, we have:

     228/1 = k/14

  cross multiply

K = 228 × 14 = 3192

 Using the same formula, we can calculate the new pressure of the gas since we know our mathematical constant and the volume it was decreased to.

  V = k/p

Here, volume = 38, k = 3192

 We now have:

   38/1 = 3192/p

 Cross multiply

 38 × p = 3192

   p = 3192/38

   p = 84 pounds per square inch.

 The new pressure of the gas after decrement of the volume= 84 pounds per square inch

When the temperature stays the same, the new pressure of the gas if the volume is decreased is 84 pounds per square inch.

Given the following data:

To find the new pressure of the gas if the volume is decreased:

Translating the word problem into a mathematical expression, we have;

[tex]V \alpha \frac{1}{P} \\\\V = \frac{k}{P}[/tex]

Where:

First of all, we would determine the constant of proportionality.

[tex]k = VP\\\\k = 228 \times 14[/tex]

k = 3,192

To find the new pressure:

[tex]P = \frac{k}{V} \\\\P = \frac{3192}{38}[/tex]

New pressure, P = 84 pounds per square inch

Answer:

= 150°

Step-by-step explanation:

Since the polygons are regular, certain mathematical assumptions would help us here.

A square is a quadrilateral with all it's 4 sides equal and all it's angles equal.

Sum of angles of a regular quadrilateral = 360.

Therefore, a single angle = 360/4

= 90°.

The Triangle is adjacent to the side of the square. We will thus assume it's an Equilateral triangle.

For an equilateral triangle, all it's 3 angles = 180.

A single angle = 180/3

= 60°.

With this,

Angle ABC = 90° + 60=

= 150°

Answer:

The circumference of the circle = 26π unit.

Step-by-step explanation:

Given:

Radius of the circle, r = "x+6"

Diameter of the circle, d = "3(x)+5"

We have to find the circumference of the circle in terms of pi.

Formula to be used:

Circumference of a circle = 2πr or πd

As we know that:

Radius = Half of diameter

So,

⇒ [tex]radius=\frac{diameter}{2}[/tex]

⇒ [tex]x+6=\frac{3x+5}{2}[/tex]

⇒ [tex]2\times (x+6)=\frac{3x+5}{2}\times 2[/tex]

⇒ [tex]2x+12=3x+5[/tex]

⇒ [tex]12-5=3x-2x[/tex]  ...Arranging variables and constants.

⇒ [tex]7=x[/tex]

Plugging x = 7 we will find the radius and the diameter.

⇒ Radius = "x+6" = "7+6" = 13

⇒ Diameter = "3(x)+5" = 3(7)+5 =26

Lets find the circumference of the circle.

⇒ Circumference = [tex]2\pi r= 2\pi (13) = 26 \pi[/tex]        Or

⇒ Circumference = [tex]\pi d=\pi (26)=26\pi[/tex]

The circumference of the circle = 26π unit.

Answer:

a:x=-3

c:x=1

Step-by-step explanation:

The zeros of a function are the values of x for which the value of the function f(x) becomes zero.

In this problem, we have the following function:

[tex]f(x)=\frac{1}{2}(x-1)(x+3)[/tex]

Here we want to find the zeros of the function, i.e. the values of x for which

[tex]f(x)=0[/tex]

In order to make f(x) equal to zero, either one of the factors [tex](x-1)[/tex] or [tex](x+3)[/tex] must be equal to zero.

Therefore, the two zeros can be found by requiring that:

1)

[tex]x-1=0\\\rightarrow x=+1[/tex]

2)

[tex]x+3=0\\\rightarrow x=-3[/tex]

So the correct options are

Answer:

[tex]P(x)=-0.3x^2+56x-14[/tex]  

Step-by-step explanation:

The given functions are

[tex]R(x)=59x-0.3x^2[/tex]

[tex]C(x)=3x+14[/tex]

It is given that

[tex]P(x)=R(x)-C(x)[/tex]

Substitute the values of given functions in the above equation.

[tex]P(x)=59x-0.3x^2-(3x+14)[/tex]

[tex]P(x)=59x-0.3x^2-3x-14[/tex]

Combine like terms.

[tex]P(x)=-0.3x^2+(59x-3x)-14[/tex]

[tex]P(x)=-0.3x^2+56x-14[/tex]  

Therefore, the required function is [tex]P(x)=-0.3x^2+56x-14[/tex]   .

Final answer:

To calculate the principal with an interest of $119.88, an interest rate of 3.6%, and a time of 3 years, use the simple interest formula. By rearranging the formula and doing the math, the principal amount is found to be $1,110.

Explanation:

To find the principal amount when you know the interest earned, the interest rate, and the time, you can use the formula for simple interest which is Interest = Principal × rate × time. Our goal is to rearrange the formula to solve for the principal.

Given that the Interest earned is $119.88, the interest rate is 3.6% (or 0.036 when converted to a decimal), and the time is 3 years, we can plug these values into the formula:

Interest = Principal × rate × time
$119.88 = Principal × 0.036 × 3
$119.88 = Principal × 0.108

To find the Principal, divide the interest earned by the product of the rate and time:

Principal = $119.88 / 0.108
Principal = $1,110

The principal amount is $1,110.

Ariel will make a bigger batch.

Step-by-step explanation:

Scott- Every 2 cups Almonds = 3 cups raisins

so 6 cups almonds = 9 cups raisins

6+9= 15

Scott's batch- 15 cups

Ariel- Every 3 cups Almonds = 5 cups sunflower seeds

so 6 cups almonds = 10 cups sunflower seeds

6+10= 16

Ariel's batch- 16 cups

16 > 15 so Ariel's is bigger.

Ariel makes the larger batch of snack mix

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Equation for Scott :

Number of cups of Almonds = 2 cups

Number of cups of Raisins for 2 cups of almonds = 3 cups

Number of cups of almonds = 6 cups

Number of cups of raisins for 6 cups of almonds = 3 x 3

                                                                                 = 9 cups

So , total number of cups by Scott =
Number of cups of almonds + Number of cups of raisins for 6 cups of almonds

Total number of cups by Scott =  6 + 9 cups

The batch of snack mix by Scott has 15 cups

Equation for Ariel :

Number of cups of Almonds = 3 cups

Number of cups of sunflower seeds for 3 cups of almonds = 5 cups

Number of cups of almonds = 6 cups

Number of cups of raisins for 6 cups of almonds = 5 x 2

                                                                                 = 10 cups

So , total number of cups by Ariel =
Number of cups of almonds + Number of cups of sunflower seeds for 6 cups of almonds

Total number of cups by Ariel =  6 + 10 cups

The batch of snack mix by Ariel has 16 cups

Therefore , the batch mix of snack by Ariel is more than the batch mix of snack by Scott

Hence , Ariel makes the larger batch

The expression simplifies to [tex]\( 2x - 4 \)[/tex] in standard form after distributing and combining like terms.

Let's break it down step by step:

1. Start with the given expression: [tex]\( \frac{1}{7}(14x+7) - 5 \)[/tex]

2. Distribute [tex]\( \frac{1}{7} \)[/tex] across the parentheses:

[tex]\[ \frac{1}{7} \cdot 14x + \frac{1}{7} \cdot 7 \][/tex]

3. Simplify each term after distributing:

[tex]\[ \frac{1}{7} \cdot 14x = 2x \][/tex]

[tex]\[ \frac{1}{7} \cdot 7 = 1 \][/tex]

4. Now, rewrite the expression with the distributed terms:

[tex]\[ 2x + 1 - 5 \][/tex]

5. Combine like terms (1 and -5):

[tex]\[ 2x + (1 - 5) \][/tex]

6. Simplify the terms inside the parentheses:

[tex]\[ 2x + (-4) \][/tex]

7. Simplify further:
