Answer:

38.8 litres

Step-by-step explanation:

22.6 + 18.7 = 41.3

41.3 - 2.5 = 38.8

38.8 litres

Answer:

38.8 liters.

Step-by-step explanation:

Word problems with addition and subtraction:

To find the quantity of water inside the bath tub, add the quantity of hot water and cold water. Then from this subtract the water that is spilled.

Quantity of water in the bathtub = 22.6 + 18.7 - 2.5

                                                      = 41.3 - 2.5

                                                      = 38.8 liters

Tristan needs to make at least 10 visits to the movie theater to earn his first free movie ticket.

Let v be the number of visits Tristan makes to the movie theater.

He receives 25 rewards points just for signing up, and he earns 8.5 points for each visit. So, the total rewards points he will have is

25+8.5v.

He needs at least 110 points for a free movie ticket. Therefore, we can write the inequality:

25+8.5v≥110

To solve for v, we can subtract 25 from both sides of the inequality and then divide by 8.5:

8.5v≥85

v≥85/8.5

v≥10

So, Tristan needs to make at least 10 visits to the movie theater to earn his first free movie ticket.

The theoretical probability of getting two tails on two coin tosses is 0.25.

The theoretical probability is the ratio of the number of favorable outcomes to the number of possible outcomes. Given a coin is tossed twice.

We have to find the theoretical probability of tossing two tails. The probability of getting tails on the toss of a coin is 1/2 0r 0.5.

Therefore, the probability of getting two tails on two coin tosses is 0.5 × 0.5 or 0.25.

The theoretical probability that a coin toss results in two heads showing is 0.25.

The arrows on the lines are trying to tell you that these lines are parallel to each other, whenever you see parallel lines think of *FUN* method

2y = 58° (alternate angles)

y = 29

x = 58° (alternate angles)

Domain:  [tex]\boldsymbol{(-\infty, \infty)}[/tex]

Range:  [tex]\boldsymbol{(-\infty, \infty)}[/tex]

=======================================================

Explanation:

domain = set of all possible x inputs

range = set of all possible y outputs

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

In this case, the domain is the set of all real numbers because the graph stretches forever to the left and right. There aren't any gaps, holes, jumps, etc to worry about. Any real number works as an input.

We can say x is between [tex]-\infty[/tex] and [tex]\infty[/tex] and write [tex]-\infty < x < \infty[/tex]

That turns into the interval notation [tex](-\infty, \infty)[/tex]

The curved parenthesis are always used with either infinity because we cannot reach them.

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

The range is the same story, but with the y values this time. The graph stretches forever upward and downward due to the arrow.

If it peaked at y = 4, then the range would be [tex](-\infty, 4][/tex], but instead the graph goes beyond y = 4 because of that upward arrow.

Answer:

1:24pm

Step-by-step explanation:

Couple of ways to solve this. Here is one method
Convert all times to minutes and find the total number of minutes they spent on all 3 activities. Then convert to hours and minutes and subtract from the end time of 5;28 to get the start time of all activities which is also the start time of watching the movie (first activity)

So time spent:

Movie: 2 hours 18 minutes = 2 * 60 + 18 = 120 + 18 = 138 minutes
Card game: 34 minutes
Soccer: 1 hour 12 minutes = 1 * 60 + 12 = 72 minutes

Total time spent = 138 + 34 + 72 = 244 minutes = 4 hours and 04 minutes

Subtract 4:04 from 5:28 to get 1:24pm

Check
Movie watch starts at 4:04, ends at 1:24 + 2:18 or 3:42pm
Card game starts at 3:42pm ends at 3:42+0:34 ==> 4:16pm
Soccer starts at 4:16pm ends at 4:16pm + 1:12 ==> 5;28pm

Answer:

Step-by-step explanation:

f(x) = x^2 – 5x + 12

The value of f(–10) = 82?     NO

f(-10) = (-10)^2 – 5(-10) + 12

f(-10) = 100 + 50 + 12

f(-10) = 162

NO

The graph of the function is a parabola.   YES

See attached graph.

The graph of the function opens down.  NO

----

Plus we can use x=20 in the function and see if it returns -8:

f(x)=x^2-5x+12

f(20)=(20)^2-5*(20)+12

f(20) = 400 - 100 + 12

f(20) = 312  It does not result in -8

Answer:

Step-by-step explanation:

Let the base camp is point A and boats' locations after two hours are points B and C.

By connecting the three points together we get a triangle ABC with sides:

The angle between AB and AC is:

We are looking for the distance BC, which can be found by using the law of cosines:

The distance between the boats is 197.93 km.

The table that matches the equation is:

Time    Calories

-20          -110

-10          -55

-15         - 82.50

-5            -27.50

The correct table would contain values that are multiples of 5.5t

For example:

Total calories burned at 20 seconds : 5.5 x 20 = 110

Total calories burned at 10 seconds : 5.5 x 10 = 55

Total calories burned at 15 seconds : 5.5 x 15 = 82.50

Total calories burned at 5 seconds : 5.5 x 5 = 27.50

Answer:
183/8 or 22.875

Step-by-step explanation:

Take 22.5 and put it over 1 so 22.5/1

And then multiply by 8 to get a common denominator (180/8) then add the 3/8 and you get 183/8 or 22.875

To solve this problem, you will first use the Angle Sum Property to determine the value of x after creating an algebraic equation, combining like terms, and subtracting from both sides of an equation.

The Angle Sum Property states that all interior angles of a triangle will summate to 180º.

An equation can be created to find this when you are given two angles and missing a third. That third angle can be referred to as x in this scenario.

Adding the two known angles and the unknown angle will result in a sum of 180º. This means that our unknown is x and can therefore be placed in an equation:

[tex]65+42+x=180[/tex]

Combine the like terms by combining the constants on the left side of the equation using addition:

[tex]65+42+x=180[/tex]

[tex]107+x=180[/tex]

After combining like terms, subtract 107 from both sides of the equation:

[tex]107 - 107 +x = 180-107[/tex]

[tex]\boxed{x=73}[/tex]

The final answer is x = 73 degrees.

The variation equation is xy = a^3

An inverse variation is represented as:

xy = k

Where k is the constant of variation

When y = a and x =a^2, we have:

k = a * a^2

Evaluate

k = a^3

Substitute k = a^3 in xy = k

xy = a^3

Hence, the equation is xy = a^3

Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

The roots of the polynomial are:

x³ - 3x² + 2

If we divide the polynomial by (x-1), then

(x³ - 3x² + 2)/(x-1) = x² - 2x - 2

now, factorize the given polynomial,

x² - 2x - 2

x = 1 ± √3
