Hey there! I'm happy to help!
Sum means to add. Let's call our number n.
n+15
We multiply this whole thing by 6.
6(n+15)
And this is -42.
6(n+15)=-42
We use distributive property to undo the parentheses.
6n+90=-42
We subtract 90 from both sides.
6n=-132
We divide both sides by 6.
n=-22.
Have a wonderful day! :D
If 30% of the students in your class like basketball, how many students are in your class if 6 students like
basketball?
The number of students in the class = 20
What is percentage?"It is a number or ratio that can be expressed as a fraction of 100."
For given example,
30 percent of the students in your class like basketball.
We need to find the total number of students if 6 students like basketball.
Let there are 'x' students in the class.
⇒ x × 30% = 6
⇒ x × (30/100) = 6
⇒ x = 6/0.3
⇒ x = 20
Therefore, there are 20 students in the class.

Zoey walks 3 blocks East and then 4 blocks North. If each block is 100 ft, how many feet is Zoey from her starting point?
Answer:
700
Step-by-step explanation:
Mr. Hernandez has 41 feet of rope to enclose a pentagonal grazing area for his sheep. Sides of the pen are represented by: x, 7 - 5x, 3x - 2, 3x + 4, 5-3x. Which inequality could be used to find the possible perimeters of the grazing area?
Answer:
Option (B)
Step-by-step explanation:
Length of the rope Mr Hernandez has = 41 feet
He wants to enclose an area in the shape of a pentagon.
Therefore, minimum length of the rope required = perimeter of the pen
Perimeter of the pentagonal pen = Sum of the measures of all five sides of the pen
Perimeter = x + (7 - 5x) + (3x - 2) + (3x + 4) + (5 - 3x)
= (-x + 14)
Now the length of the rope should be more than and equal to the perimeter of the pen to cover.
41 ≥ (-x + 14)
Or
-x + 14 ≤ 41
Therefore, Option (B) will be the answer.

What is a Set?The definition of a set in mathematics is a group of things whose components are unchangeable and fixed. In other words, a set is accurately described as a group of data that does not pass from one person to another. The items can be written in any sequence, but they cannot be repeated in the set. Capital letters are used to denote the set.
Several other kinds of sets include the infinite set, the finite set, the equivalent set, the subset, the universal set, and the superset. Each kind of set has a different place in calculations. Sets are essentially used to represent large amounts of data and collections of data in everyday life. Thus, in this article, we'll learn about and talk about the universal set.
As per the given data:
The integer set is {7, -7, -3, 3}
For the greatest value, arranging the set in ascending order:
{-7, -3, 3, 7}
The greatest value will be 7.

Help 10 points 30 minutes to answer
Answer:
The first answer choice.
Answer choice A.
Step-by-step explanation:
The domain of a function would be the set of all possible x-values of that function.
Since we are looking for the domain, the set of the possible x-values, we can eliminate any answer choices that are a set of y-values. B and D are eliminated.
From what we can see in the table, the possible x-values of the function are -6, -1, 0 and 3. Although C does include these values in the set, it also includes many other values. As we can see, answer choice A includes the x-values given in the table and only those values. Therefore, answer choice A is the correct answer.
I hope you find my answer and explanation helpful. Happy studying.
y intercept = ?
x intercept = ?
I need help in my Aleks homework :)
Answer:
y-intercept: 2
x-intercept: -2, 4
Step-by-step explanation:
Y-intercepts and x-intercepts are points on the graph that are on the y-axis and x-axis, respectively.
Looking at the graph, the graph passes through the y-axis at y=2. Therefore, the y-intercept is 2.
Looking at the graph, the graph passes through the x-axis at x=-2 and x=4. Therefore, the x-intercepts are -2 and 4.

Determine the mean and the mean absolute deviation (MAD).
(PLEASE HELPPP!!!!!!)
Answer:
Mean Absolute Deviation = 2.4
Step-by-step explanation:
Find you have to find the mean (average):
3 + 5 + 7 + 9 + 11 = 35
35 / 5 = 7
Mean = 7
The mean absolute deviation is the mean (average) of the distance from the other numbers (absolute means that if the number is negative it turns into a positive):
3 - 7 = 4
5 - 7 = 2
7 - 7 = 0
9 - 7 = 2
11 - 7 = 4
Now we have to find the mean of this numbers:
4 + 2 + 0 + 2 + 4 = 12
12 / 5 = 2.4
Mean Absolute Deviation = 2.4
Answer:
2.4
Step-by-step explanation:

Write an addition expression to describe the situation. Then find the sum and select the correct answer below. A hiker starts at 200 ft. above sea level and then hikes up the mountain 1,500 more feet. When coming down the other side of the mountain, she descends 500 before taking a ten-minute break. How high above sea level is she during this ten-minute break?
A 1,700 ft. B1,000 ft. C1,200 ft. D1,190 ft.
Answer:
(200+1,500) - 500 = 1,200 ft
Step-by-step explanation:
the hiker started at 200 ft then went 1500 more feet. (add it up) Then, she descends (goes down) 500 feet. So let's subtract 500 feet from the sum of 200 and 1500. ( (200+1500 equals 1700, then subtract 500 which will be 1200.) ) So, she is 1200 feet above sea level during the 10 minute break.

Take the L.C.M of 12 and 8
To find out the L.C.M , first of all find the prime factors of each numbers.
12 = 2 × 2 × 3
8 = 2 × 2 × 2
Take out the common prime factors : 2 and 2
Also, take out the remaining prime factors: 3 and 2

whats the mean of -54 -32 -70 -25 -65 and -42 please help need the answer for a math quiz?!
Step-by-step explanation:
To find the mean, you add all the numbers and divide by how many there are.
In this case, you add -54,-32,-70,-25,-65, and -42. Then you divide by 6 because there are 6 numbers.
When you add them all, you get -288.
Now divide.
-288/6=-48
Hope it helps!
Answer:
-48
so you add all the numbers together, which will give you -288
there are 6 terms, so you divide -288 by 6
gives you your answer of -48

1. Express 53 pm, the size of a hydrogen atom, in scientific notation
Answer:
[tex]5.3\times 10^{-11}\ m[/tex]
Step-by-step explanation:
In this problem, we need to express 53 pm in which is the size of a hydrogen atom, in scientific notation.
Any number can be expressed in scientific notation as follows :
[tex]N=a\times 10^b[/tex]
a is any real no and b is any integer
We know that, 1 pm = [tex]10^{-12}\ m[/tex]
It means, [tex]53\ pm=53\times 10^{-12}\ m[/tex]
or
[tex]53\times 10^{-12}\ m=\dfrac{53}{10}\times 10^{-12}\times 10\\\\=5.3\times 10^{-12+1}\\\\=5.3\times 10^{-11}\ m[/tex]
Therefore, the above is the scientific notation for the size of a hydrogen atom.

Area of a circle = [tex]\pi r^{2}[/tex]
Area of a circle = 3.14 * 3 * 3 ( so i used pi as 3.14 ) then the radius is 3
Area of a circle = 9.42 * 3 ( first 3.14 times 3 is 9.42)
Area of a circle = 28.26 ( 9.42 times 3 is 28.26)
