Answer:
3 1/6
Step-by-step explanation:
First, we turn 11/12 and 3/4 to have the same denominator
3/4 x 3 is 9/12
11/12- 9/12 is 2/12
Now we add the extra 3 to 2/12 which is 3 2/12
3 2/12 can be simplified to 3 1/6
Write an equation in slope-intercept form for each table below. Show how you found the slope and y-intercept.
The linear functions for the tables given are as follows:
1. y = 2.5x.
2. y = x + 1.
3. y = 3x - 1.5.
4. y = -4x + 3.
5. y = 4x + 1.
What is a linear function?A linear function is modeled in slope-intercept form by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For each function, the slope and the intercept are found as follows:
For item 1, when x = 0, y = 0, hence the intercept is of b = 0. When x increases by 1, y increases by 2.5, hence the slope is of m = 2.5.For item 2, when x = 0, y = 6, hence the intercept is of b = 1. When x increases by 1, y increases by 1, hence the slope is of m = 1.For item 3, when x = 0, y = -1.5, hence the intercept is of b = -1.5. When x increases by 1, y increases by 3, hence the slope is of m = 3.For item 4, when x = 0, y = 3, hence the intercept is of b = 3. When x increases by 1, y decreases by 4, hence the slope is of m = -4.For item 5, when x = 0, y = 1, hence the intercept is of b = 1. When x increases by 1, y increases by 4, hence the slope is of m = 4.Hence the functions are given as follows:
1. y = 2.5x.
2. y = x + 1.
3. y = 3x - 1.5.
4. y = -4x + 3.
5. y = 4x + 1.

PLS HELP ME 50 POINTS!!!!! I NEED AN ANSWER ASAP!!!!!!
A large downtown hotel consists of twenty-four levels. Any level above ground is referred to as a" floor". There are twenty-two floors and each floor corresponds to its number on the number line (2 is second floor, 3 is third floor, etc...) and two underground levels reserved for underground parking. The first level below ground level is Parking A, and the second level below ground level is labeled Parking B.
Use the provided horizontal number line to help you answer the following questions.
If you start at Parking B and take the elevator to the fourteenth floor, how many levels have you gone up? [Type your answer as a number.]
Answer:
They went up 16 levels.
Step-by-step explanation:
You can find that by finding the distance from -2 to 14.
To find the distance from two numbers, [tex]a[/tex] and [tex]b[/tex], we can substitute both in the formula [tex]d = |b - a|[/tex], where d is the distance between them.
[tex]d = |14 - (-2)| \to |14 + 2|\to|16|\to16[/tex]
Answer:
16 levels
Step-by-step explanation:
since there is 24 levels
and parking b is the lowest of the twenty-four
2(underground levels) + 14 ( floors)
= 16 levels

John wants to hit homeruns for his baseball team. He wants to be within 5 homeruns of hitting 30 for the year. Write an absolute value equation of the given situation.
He wants to be within 5 homeruns of hitting 30 for the year, therefore he needs 25 home runs.
How to illustrate the information?From the information, it was stated that John wants to hit homeruns for his baseball team and that he wants to be within 5 homeruns of hitting 30 for the year.
Let the number of home runs be represented by x.
Therefore, x + 5 = 30
x = 30 - 5
x = 25
Therefore, since he wants to be within 5 homeruns of hitting 30 for the year, he needs 25 home runs.

d) discrete.
e) continuous.
f) discrete.
Is the situation an example of a continuous or discrete relation?A continuos variable can take any value in a dense set, while a discrete variable can only take some selected values.
a) "Bag of apples"
Here the variable is the number of apples in the bag, we can only have whole numbers of apples, then this variable is discrete.
b) "Distance from here to the moon"
This is a distance, so the value is continuous.
c) "Area of a circle"
Exactly like in the case above, the area is continuous.
d) "Number of telephone calls made each day"
Like in the first example, here the variable can only take whole numbers thus, it is discrete.
e) "The height of a ball as it is thrown into the air."
Similar than case b, a height can take any value on a given range, thus, this is continuous.
f) "The balance in an account over a week."
Here the balance can only be a number followed by 2 digits after the decimal point, so from:
$23.50
We can only go up to:
$23.51
Then all the values in between are not allowed, this means that the variable is discrete.

The mass of a paperclip is 7.0 * 10^(-4) mg. If a box of paper clips has (3.18 10^(4) paper clips, determine the total mass of the paper clips in the box. Write the final answer in scientific notation with the correct number or significant digits.
2.2 * 10^1 mg
2 * 10^1 mg
2.226 * 10^1 mg
2.23 * 10^0 mg
The total mass of the paper clips in scientific notation is 2.226*10 mg
How to get the total mass of the paper clips?
We know that the mass of a single paper clip is:
M = 7.0*10⁻⁴ mg
And in one box has a total of 3.18*10⁴ clips inside of it, then the total mass of the paper clips on the box will be equal to the product between the mass of a single clip and the total number of clips.
We will get:
total mass = (7.0*10⁻⁴ mg)*(3.18*10⁴)
Using the associative property we can rewrite:
total mass = (7.0*3.18)*(10⁻⁴*10⁴) mg
= (22.26)*(10⁰) mg = 22.26 mg
Now we want to write this in scientific notation, so we need to have a single digit in the left of the decimal point, then we can rewrite this as:
22.26 mg = 2.226*10 mg

Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options. x2 + (y – 3)2 = 36 x2 + (y – 5)2 = 6 (x – 4)² + y² = 36 (x + 6)² + y² = 144 x2 + (y + 8)2 = 36
Answer:
x² + (y – 3)² = 36
and
x²+ (y + 8)²= 36
Step-by-step explanation:
The equation of circle that has a center (a, b) is given by the formula
(x - a)² + (x - b)² = r²
where r is the radius of the circle
If the circle lies on the y axis, its x-coordinate must be 0.
The radius of the circle = 1/2 x diameter = 1/2 x 12 = 6 units
So the equation must be of the form
(x - 0)² + (y - b)² = 36
We can eliminate x² + (y – 5)² = 6
We can also eliminate (x + 6)² + y² = 144
That leaves us with the two possible equations
x² + (y – 3)² = 36 (center at 0, 3)
and
x²+ (y + 8)²= 36 (center at (0, -8) )

What is the value of angle y as represented in the image attached to the task content?It follows from the task content that the value of angle y is to be determined from the image attached to the task content.
On this note, one must recall that from polygon theorems; the sum of all exteriors angles of a polygon is equal to; 360°.
Therefore; we have;
60° + 70° + 65° + 40° + y° = 360°
By isolating y°; we have;
y° = 360° - 60° - 70° - 65° - 40°
y° = 125°
Ultimately, the measure of the angle labelled y as represented in the image attached to the task content is; 125°.

The median class is 40 -60 as cf ≥ N/2
which is 33 ≥ 25
medain = 40 + |25-15|/18 ×20
medain = 40 + 200/18
median = 41.111
Mode = lower limit + f1-f0/2f1-f0-f2 × height
Here, f1 is the frequency of the modal class = 18.
f0 is the frequency of the preceding modal class = 9.
f2 is t/he frequency of the succeeding modal class = 13.
Mode = 40+ 18-9/2(18)-9-13
Mode = 52.857
Hence, the modal price is 52.857.

The standard deviation of the data is calculated as,
SD = √(∑f(x1)^2)/N - (mean)^2

1 teaspoon of 3. Natasha made a sauce in cooking class. She used 2 cups of cream, salt, cup of chives and 1 cups of butter. Approximately how many cups of 4 A ingredients did she use?,
We need to know about mixed fraction to solve this problem. Natasha used approximately 4 cups of ingredients.
A mixed fraction is a fraction that is represented with its quotient and remainder. For example there is a mixed fraction [tex]5\frac{2}{3}[/tex] where 5 is the quotient and 2 is the remainder. To convert a mixed fraction to a simple fraction we multiply the denominator by the quotient and add the remainder to it to get the numerator of the simple fraction, the denominator remains the same. In this question we have to find the cups of ingredients that Natasha uses to make the sauce, we have to simplify all the mixed fractions and then add the fraction together to get the number of cups.
cups of cream=[tex]2\frac{3}{4}[/tex]=11/4
teaspoon of salt =1/2
cups of chive=3/8
cups pf butter=[tex]1\frac{1}{4}[/tex]=5/4
total cups of ingredients used= 11/4+3/8+5/4=(22+3+10)/8=35/8≈4 cups
Therefore we found out that the total number of cups natasha uses to make the sauce is 4.
