The sum of two angles is 180. One of the angles measures 96 degrees. What is the measure of the second angle?

Answer:

17.325 liters

Step-by-step explanation:

Given

Muriatic acid needed by one hot tub = 165 ml

Total hot tubs: 105

So, in order to find the total quantity of muriatic acid, the quantity for one tub will be multiplied by total tubs

So,

Total quantity of muriatic acid: 105 * 165

= 17325 ml

Since we have to find the answer in liters.

1 liter contains 1000 milliliters.

So,

for 17325 ml

= 17325 / 1000 = 17.325 liters

Hence, Apollo Spas needs 17.325 liters of muriatic acid for all of the hot tubs ..

Answer:

17.325 liters

Step-by-step explanation:

Number of Apollo Spas Services= 105 hot tubs

Each hot tub needs Muriatic acid= 165 ml

We have to find the total liters of muriatic  acid

Total number of liters required = Number of hots cups× 165 ml

Total number of liters required= 105×165 ml

Total number of liters required= 17,325 ml

1ml = 1/1000 liters

Total number of liters required= 17.325 liters

Hence, the correct answer is 17.325 liters

Step-by-step explanation:

These I's are being used as sticks

lets say i have 40 sticks then i add 55 more sticks to them

IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII + IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII If i were to reverse the sequence and use the 55 sticks and add 44 sticks to them it would be the same as me having 44 sticks and adding 55 more.

By commutative property, the following which is equal to 40 + 55 is Option(D) 55 + 40.

The commutative property is a math rule that says that the order in which we find the sum of the numbers does not change the sum up value of the numbers.

By the statement,

A + B = B + A , where A and B are any numbers

The original expression given is 40 + 55 .

Therefore by commutative property, the equivalent expression is -

40 + 55 = 55 + 40

Thus, by commutative property, the following which is equal to 40 + 55 is Option(D) 55 + 40.

Final answer:

To find the length of the ladder, use the tangent of the angle of elevation. The height of the ladder is equal to the distance from the house multiplied by the tangent of the angle of elevation.

Explanation:

To find the length of the ladder, we can use the trigonometric relationship of the angle of elevation. The tangent of the angle of elevation is equal to the opposite side (height of the ladder) divided by the adjacent side (distance of the ladder from the house).

Tan(69°) = height/12 ft

height = 12 ft x tan(69°)

Using a calculator, we can determine that the height of the ladder is approximately 31.99 ft.

Your answer asks to find the median of the given numbers.

To find the median, you would need to sort of the numbers from least to greaters.

The given numbers we have:

12, 8, 5, 6, 1, 10, 13, 11

Now, just sort them from least to greatest.

1, 5, 6, 8, 10, 11, 12 ,13

What you would do next is eliminate the numbers on the side, one by one, in order to get your median.

[tex]1, 5, 6, 8, 10, 11, 12 ,13\\\\5, 6, 8, 10, 11, 12\\\\6, 8, 10, 11\\\\8, 10[/tex]

We ended up with two numbers, 8 and 10. Since we didn't end up with one number, we're going to have to add those numbers, and then divide it by two.

[tex]8+10=18\\\\18\div2=9[/tex]

To solve the problem, we need to look for the characteristics of the line.

We can see that:

- The line has a positive slope since the coefficient of the linear term is a positive number (2).

- Since the line has a positive slope, the line is increasing.

From the line we can calculate the axis intercepts:

For the x-axis intercept, making "y" equal to 0, we have:

[tex]y=2x+1\\\\0=2x+1\\\\x=-\frac{1}{2}=-0.5[/tex]

We have that the x-axis interception point is located at the point (-0.5,0)

For the y-axis intercept, making "x" equal to 0, we have:

[tex]y=2x+1\\\\y=2*0+1\\\\y=1[/tex]

We have that the y-axis interception point is located at the point (0,1)

Also, we have a "less" symbol for the inequality, meaning that the shade that represents the solution of the inequality is located under the pointed line.

Option C

The area of the parking lot without considering the arena is determined to be 6518.75 square units.

To determine the parking lot area excluding the arena, the process involves multiple steps:

Parking Lot Area Calculation:

Utilize the formula A = B x H, where B is the base (100) and H is the height (75).

Compute A = 100 x 75, resulting in an initial parking lot area of 7500 square units.

Arena Area Calculation:

Employ the formula A = π r², where r is the radius (25) of the arena.

Calculate A = π x 25², yielding an arena area of 19625 square units.

Adjustment for Arena Area:

Observe the image indicating that the car park bisects the arena, cutting its area in half.

Subtract half of the arena's area from the parking lot area to obtain the adjusted area within the car park.

The adjustment equation is A = area - 0.5 x arena, where area is the parking lot area (7500) and arena is half of the arena's area (19625 / 2 = 981.25).

Final Result:

Perform the subtraction: A = 7500 - 981.25, yielding a final area of 6518.75 square units.

Therefore, the area of the parking lot without considering the arena is determined to be 6518.75 square units.

Answer:

[tex]\frac{4}{15}[/tex] of the pizza has both pepperoni and onions.

Step-by-step explanation:

As we know, [tex]\frac{2}{5}[/tex] of the pizza has pepperoni and [tex]\frac{1}{3}[/tex] of it is onions.

[tex]\frac{2}{5}[/tex] + [tex]\frac{1}{3}[/tex]

= [tex]\frac{6}{15}[/tex] + [tex]\frac{5}{15}[/tex]     (because you have to find like denominators when you add)

= [tex]\frac{11}{15}[/tex]

[tex]\frac{11}{15}[/tex] of the pizza have one topping.

The whole is 1, or [tex]\frac{15}{15}[/tex]. So,

[tex]\frac{15}{15}[/tex] - [tex]\frac{11}{15}[/tex] = [tex]\frac{4}{15}[/tex].

[tex]\frac{4}{15}[/tex] of the pizza have both pepperoni and onions.

Final answer:

Two-fifths (2/5) of the pizza has just pepperoni and one-third (1/3) has just onions. Since the sum of these portions exceeds one, we find the overlap by subtracting one from the sum (11/15 - 15/15), resulting in 4/15 of the pizza having both pepperoni and onions.

Explanation:

Cindi bought a sheet pizza for a party with some sections having different toppings. To find out what fraction of the pizza has both pepperoni and onions, we'll first consider the fractions of the pizza with individual toppings. Two-fifths (2/5) of the pizza has just pepperoni and one-third (1/3) has just onions. The sum of these fractions exceeds one, indicating an overlap which must be the part with both toppings.

To calculate the overlap, we add the fractions for just pepperoni and just onions:
2/5 + 1/3 = 6/15 + 5/15 = 11/15.

Since the total cannot exceed one whole pizza, the overlap - the portion with both toppings - is the amount that the sum of individual parts exceeds one. Therefore, we subtract one from the combined fraction:
11/15 - 1 (which equals 15/15) equals -4/15. This negative value is indicative of the overlap. Therefore, 4/15 of the pizza has both pepperoni and onions.

First add 3 to both sides (what you do on one side you must do to the other). Since 3 is being subtracted, addition (the opposite of subtraction) will cancel it out (make it zero) from the right side and bring it over to the left side.

1 > s - 3

1 + 3 > s - 3 + 3

4 > s

For the graph will you have a empty or colored in circle?

If the symbol is ≥ or ≤ then the circle will be colored in. This represents that the number the circle is on is included.

If the symbol is > or < then the circle will be empty. This represents that the number the circle is on is NOT included.

Which direction will the ray go?

If the variable is LESS then the number then the arrow will go to the left of the circle.

If the variable is MORE then the number then the arrow will go to the right of the circle.

In this case your inequality is:

4 > s OR s < 4

aka 4 is greater then s OR s is less then 4

This means that the graph will have an empty circle and the arrow will go to the left of 4. Look at image below.

Answer:

These kind of problem can be modeled by using the following equation

y = Po*e^(k*(t-to))

Where

Po = initial population

to = year of the initial population

y = Number of students at current year

k = constant rate of change

t = time in years

In 2012

695 = Po*e^(k*(2012 - 2012))

Po = 695

In 2016

825 = 695.e^(k*(2016-2012))

825/695 = e^(k*(4))

ln(825/695) = 4*k

k = ln(825/695) / 4

k = ln(825/695) / 4

k = 0.04287

in 2018

y = 695*e^(0.04287*(2018-2012))

y = 695*e^(0.04287*(6))

y = 695*e^(0.257)

y = 695*1.293

y = 898.85

approximately

899 students

Final answer:

The predicted school population in 2018, based on a constant rate of change, is 890 students. This is calculated by determining the annual rate of increase between 2012 and 2016 and applying it to the 2016 population.

Explanation:

To predict the population of the school in 2018, we need to calculate the constant rate of change between 2012 and 2016, and then apply that rate to extend the prediction to 2018. From 2012 to 2016, the school's population grew from 695 to 825 students. This is an increase of 825 - 695 = 130 students over 4 years.

The annual rate of change is thus 130 students
over 4 years = 32.5 students per year. To predict the population for 2018, we add twice the annual rate of change to the 2016 population (since 2018 is two years after 2016): 825 + (2 * 32.5) = 825 + 65 = 890 students.

Therefore, we can predict that the school population in 2018 will be 890 students.

Answer:

B. 24 yd^2

Step-by-step explanation:

Let A denote the area of the smaller figure:

We can determine the ratio of both lengths and areas as:

3:5 :: A:40

As the areas of figures vary directly with their lengths and widths so the proportion will be direct proportion.

Converting into fractions will give us:

3/5 = A/40

Now we have to find the value of A for the area of smaller figure.

Cross multiplication will give us:

3*40 = 5A

=> 120 = 5A

The ordered pair which will be found in the graph of the inverse function is:

C.  (0,-2) , (4,-1) , (8,0) , (12,1) , (16,2)    

We are given a table of values as:

       x                f(x)

     -2                 0

     -1                  4

      0                  8

      1                   12

      2                  16

i.e. the domain of the function is: {-2,-1,0,1,2}

and range of the function is: {0,4,8,12,16}

We now that for any function f(x) and it's inverse function the x and y value get interchanged i.e. the domain of the function f(x) becomes the range of its inverse function and the range of the function f(x) becomes the domain of the inverse function.

Hence, for any function with given ordered pair the inverse function will have ordered pair with x and y-value getting swapped.

i.e. if (-2,0) is an ordered pair of f(x)

then (0,-2) will be an ordered pair in the inverse function of f(x).

Hence, similarly all the ordered pairs could be obtained.

            The answer is:

             Option: C
