Answer:

The coefficient is 6

Step-by-step explanation:

The coefficient is the number before the variable

In this case, the variable, or the unknown value, is x.

Ax^n

A is the coefficient

We have been given that a rectangular yard is fenced in using 319 feet of custom fence Your friends really like the fence and decide to fence in their yard using the same fence.  Their yard is similar but has a scale factor of 8/5 times the size of  yours.

We are asked to find the length of fence that your friends should purchase.

Since the size of your friend's yard is [tex]\frac{8}{5}[/tex] times your yard, so your friend should purchase [tex]\frac{8}{5}[/tex] times the 319 feet.

[tex]\text{Length of fence your friend should purchase}=\frac{8}{5}\times 319\text{ ft}[/tex]

[tex]\text{Length of fence your friend should purchase}=8\times 63.8\text{ ft}[/tex]

[tex]\text{Length of fence your friend should purchase}=510.4\text{ ft}[/tex]

Upon rounding our answer to nearest foot, we will get:

[tex]\text{Length of fence your friend should purchase}\approx 510\text{ ft}[/tex]

Therefore, your friends should purchase 510 feet of fence and option C is the correct choice.

Answer:

Step-by-step explanation:

Here we have the length of the hypotenuse (16) and that of the vertical leg (11).  The cosine function inputs this data:

            adjacent side                11

sin x = -----------------------  =  ----------------  =  0.6875

              hypotenuse                 16

We find x using the arccos function:  arccos 0.6875 = 0.81 radians or

Mixed fractions are a fraction that represents their quotient and remainder. It is a type of fraction in which the whole number part and fractional part is present.

At first, we have to find the common denominator LCD [tex]=11*5=55[/tex];

Now, [tex]\frac{36}{11}=\frac{180}{55}[/tex]  and [tex]\frac{17}{5}=\frac{187}{55}[/tex]

So, from above we get;

[tex]\frac{181}{55} , \frac{182}{55},\frac{183}{55}, \frac{184}{55} ,\frac{185}{55} ,\frac{186}{55}[/tex] as mixed fractions between given mixed fractions.

Again, we will multiply both denominator and numerator by 2, and we get;

[tex]\frac{180}{55}=\frac{360}{110}[/tex]  and [tex]\frac{187}{55} =\frac{374}{110}[/tex]

So, repeating the same step, we get;

[tex]\frac{361}{110},\frac{362}{110} ,\frac{363}{110} ,\frac{364}{110} ,\frac{365}{110},\frac{366}{110} ,\frac{367}{110} ,\frac{368}{110},\frac{369}{110} ,\frac{370}{110} ,\frac{371}{110} ,\frac{372}{110} ,\frac{373}{110}[/tex] are mixed fractions

between given mixed fractions.

A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, 1 is the remainder. So, a mixed fraction is a combination of a whole number and a proper fraction

A mixed fraction is one whose value is always greater than 1 and it has a whole number part and a proper fraction. For example, 325 3 2 5 is a mixed number. An improper fraction is one in which the numerator is always greater than or equal to the denominator.

Answer:

9 and 11

Step-by-step explanation:

The sum of the squares of two consecutive positive odd integers is 202.

Let first number be x and other number is (x+2).

According to question,

[tex]x^2+(x+2)^2=202\\\\x^2+x^2+4+4x=202\\\\2x^2+4x+4=202\\\\2x^2+4x-198=0[/tex]

It is a quadratic equation. The solution of a quadratic equation is given by :

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

We have, a = 2, b = 4 and c = -198

So,

[tex]x=\dfrac{-b+ \sqrt{b^2-4ac} }{2a}, \dfrac{-b- \sqrt{b^2-4ac} }{2a}\\\\x=\dfrac{-4+ \sqrt{4^2-4\times 2\times (-198)} }{2(2)}, \dfrac{-b- \sqrt{b^2-4ac} }{2a}\\\\x=9, -11[/tex]

So, first positive odd integer is 9 and second one is (9+2)=11

Answer:

y = - 2(x - 2)² - 3

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (2, - 3) , thus

y = a(x - 2)² - 3

To find a substitute (1, - 5) a point on the curve into the equation

- 5 = a(1 - 2)² - 3

- 5 = a - 3 ⇒ a = - 5 + 3 = - 2

y = - 2(x - 2)² - 3 ← equation in vertex form

Answer:

Pizza: 27°

Curry: 108°

Fish and Chips: 63°

Kabab: 27°

Other: 135°

Step-by-step explanation:

Frequency 40 = 360°

Pizza (3) = [tex]\frac{3}{40}[/tex] * 360° = 27°

Curry (12) = [tex]\frac{12}{40}[/tex] * 360° = 108°

Fish and Chips (7) = [tex]\frac{7}{40}[/tex] * 360° = 63°

Kabab (3) = [tex]\frac{3}{40}[/tex] * 360° = 27°

Other (15) = [tex]\frac{15}{40}[/tex] * 360° = 135°

27 + 108 + 63 + 27 + 135 = 360

Answer:

D, 34,000 milliliters

Step-by-step explanation:

There are 1,000 milliliters in a liter. So, if we had 1 liter, we would have 1*1,000=1,000 milliliters.

When you change the 1 liter to 34, we can just substitute 34 for 1. So, the answer is 34*1,000=34,000 milliliters, or D

Answer:

The area of the circle is 2520 cm²

Step-by-step explanation:

The area of an arc is given by the following formula:

arc area = pi*r²(angle/360)

In this case we have the area and the angle and we want to find r, so we have:

210 = pi*r²*(30/360)

210 = pi*r²*(1/12)

210*12 = pi*r²

pi*r² = 210*12

r² = 2520/pi

r = sqrt(2520/pi)

r = 28.3221

The area of the circle that has this arc is given by:

area = pi*r²

area = pi*(28.3221)² = 2520 cm²
