What is the volume of the figure? Enter the answer in the box.

Answer:

r=7

Step-by-step explanation:

6r-7+90+55=180

6r+138=180 ----- 6r=180-138

6r=42 ----- divide both sides by 6

r=7

(We get the 90 from the 90degrees in the middle of this supplementary angle and the total, 180, from the straight angle made from all three angles.)

Answer:

Given,

Area of the Square = ( x² - 10x + 25 ) m²

We have to find: Length of the side of the square.

Let s be the side of square.

We find length of side of the by using factorization.

According to the question,

s² = x² - 10x + 25

s² = x² - 5x - 5x + 25

s² = x( x - 5 ) - 5( x - 5 )

s² = ( x - 5 )( x - 5 )

s² = ( x - 5 )²

Taking square root on both sides we get,

s = x - 5

Therefore, Expression that represents the length of one side of the square is x - 5.

The number of pennies is on the [tex]\rm n^t^h[/tex]square is  [tex]\rm 2^n^-^1[/tex].

I am assuming the:

1 penny = [tex]2^0[/tex]

2 pennies = [tex]2^1[/tex]

3 pennies = [tex]2^2[/tex]

and so on.

It is required to find how many pennies are on the [tex]\rm n^t^h[/tex]  square.

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have:

1 penny = [tex]2^0[/tex]

2 pennies = [tex]2^1[/tex]

3 pennies = [tex]2^2[/tex]

If we observe the pattern, we see it on the  [tex]\rm n^t^h[/tex]  square the number of pennies will be [tex]\rm 2^n^-^1[/tex]

[tex]\rm n^t^h= 2^n^-^1[/tex]

Thus, the number of pennies is on the [tex]\rm n^t^h[/tex]square is  [tex]\rm 2^n^-^1[/tex].

This is the only way I can think of this mathematically. This took a good 20 minutes for me. You need to guess and check. Like try 17 quarters, 50 nickels, and 37 dimes etc. until you get 11.00. My numbers are mathematically correct but we both know you cant have 18.909 quarters so. lol

Answer:

Quarters: 18.909

Nickels: 49.818

Dimes: 37.818

Somewhere around those numbers.

Step-by-step explanation:

$11.00 total in coins

Nickel = $0.05

Dime = $0.10

Quarter = $0.25

(n*0.05) + (d*0.10) + (q*0.25)

Solve the equation for q.

[tex]q=\frac{1}{2} d[/tex]

(n*0.05) + (d*0.10) +( [tex]\frac{1}{2} d[/tex] *0.25)

Simplify the expression.

9d + 2n = 440

d - n = -12

Multiply both sides of the equation by -9.

-9d + 9n = 108

9d + 2n = 440

Sum the equations vertically to eliminate at least one variable.

11n = 548

[tex]n=\frac{548}{11}[/tex]

Substitute the given value of n into the equation d - n = -12

[tex]d-\frac{548}{11} =-12[/tex]

[tex]d=\frac{416}{11}[/tex]

Substitute the given value of n into the equation [tex]q=\frac{1}{2} d[/tex]

[tex]q=\frac{1}{2} *\frac{416}{11}[/tex]

[tex]q=\frac{208}{11}[/tex]

Finally

[tex]d=\frac{416}{11}[/tex]        d = 37.818

[tex]n=\frac{548}{11}[/tex]        n = 49.818

[tex]q=\frac{208}{11}[/tex]        q = 18.909

A linear inequality resembles in form an equation, but with the equal sign replaced by an inequality symbol. The solution of a linear inequality is generally a range of values, rather than one specific value. Such inequalities arise naturally in problems involving words such as 'at least' or 'at most'.

the parallel line is y = 8x + 6

Step-by-step explanation:

so to solve for a parallel line we already know that the slopes are the same. so rn we can write:

y = 8x + b

but since we do not know the y-intercept we can use the points given to find it

we substitute them

-2 = 8(-1) + b

-2 = -8 + b

b = 6

the parallel line is y = 8x + 6

The total cost of the loan goes down as the term decreases. Although the amount of the loan itself remains the same, the total amount of interest Maria would have to pay in interest decreased when the term of the loan decreased. However, the monthly payments increased when the term decreased. So, a shorter term saves interest but requires greater monthly payments.

Answer:

(4, 3 )

Step-by-step explanation:

2x - 4y = - 4 → (1)

2x + y = 11 → (2)

subtract (2) from (1) term by term to eliminate x

(2x - 2x) + (- 4y - y) = - 4 - 11

0 - 5y = - 15

- 5y = - 15 ( divide both sides by - 5 )

y = 3

substitute y = 3 into either of the 2 equations and solve for x

substituting into (2)

2x + 3 = 11 ( subtract 3 from both sides )

2x = 8 ( divide both sides by 2 )

x = 4

solution is (4, 3 )

Considering the points on the unit circle, it is found that the angle is on the second quadrant, hence the possible angles are between 90º and 180º.

For an angle [tex]\theta[/tex] the unit circle is a circle with radius 1 containing the following set of points: [tex](\cos{\theta}, \sin{\theta})[/tex].

In this problem, we have a negative cosine and a positive sine, hence it is an angle on the second quadrant, which can be values between 90º and 180º.

Answer:

450 minutes

Step-by-step explanation:

First, let's calculate the volume of the pool when filled.  Volume will be: (length x width x height).

Volume = 6' x 5' x 2 ' = 60 ft^3

1 ft^3 of water occupies 7.5 gallons.  That's a conversion factor for water:  (7.5 gal)/(1 ft^3).

The total gallons of water in a filled pool would be:\

(60 ft^3)*((7.5 gal)/(1 ft^3)) = 4500 gallons

At a rate of 10 gallons/min, it would take:

(4500 gallons)/(10 gallons/min) = 450 minutes, or 450/60 = 7.5 hours
