P = 2((10 + x) + x)
The perimeter of a rectangle is the sum of the length and width multiplied by 2
P = 2(l + w)
[to simplify the expression]
P = 2 × (l + w)
[using x to represent the width]
w = x
l = x + 10
P = 2 × ((10 + x) + x)
P = 2((10 + x) + x)

What is the slope of the line represented by the equation 3x– 4y = 7?
Answer:
slope = [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x - 4y = 7 ( subtract 3x from both sides )
- 4y = - 3x + 7 ( divide terms by - 4 )
y = [tex]\frac{3}{4}[/tex] x - [tex]\frac{7}{4}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{3}{4}[/tex]

The smallest known galaxy, Segue 2, has an approximate radius of 1.05 × 1015 kilometers. Use the conversion factors 1 light-year = 9.5 × 1012 kilometers and 1 parsec = 3.262 light-years to convert this distance from kilometers to parsecs.
Answer:
33.88 parsecStep-by-step explanation:
Given:
1 light-year = 9.5 × 10¹² kilometers1 parsec = 3.262 light-yearsConvert parsec to km:
1 parsec = 3.262 * 9.5 × 10¹² = 30.989 × 10¹² = 3.0989 × 10¹³Find the radius of Segue 2 in parsecs:
1.05 × 10¹⁵ / 3.0989 × 10¹³ = 105 × 10¹³ / 3.0989 × 10¹³ = 105/3.0989 = 33.88 parsecTranslate each sentence into an equation.The sum of five times h and twice g is equal to 23.

Answer:
107
Step-by-step explanation:
Angle 1
When a line is passes through a straight line, the two angles must equal 180 degrees. Since you know the one angle is 81, then angle 1 is 180 - 81 or
99 degrees.
Angle 2
You can determine the angle that is opposite of the 91 angle. These two angles must add up to 180. So the angle to the right of 91 must be 89.
89 + 91 = 180
You were told lines c and d are parallel. Based on that, the angle you just calculated must be equal to angle 2 or 89 degrees.
Angle 3
Again, you know that lines c and d are parallel. When a line crosses over two parallel lines, the outer opposite angles would be equal to each other.
So angle 3 is equal to the angle marked as 81 degrees.
Angle 1 + Angle 2 - Angle 3 = 107
find the value of k if it is known that the graph of y=kx+2 goes through the point. a(14,-40)
(100 POINTS)
Answer:
k=-3
Explanation:
Plug in x and y values
-40=k(14)+2
-2 both sidea
-42=k(14)
divide by 14 both sides
k=-3
k = -3
Step-by-step explanation:
y = kx + 2 through the point a(14, -40)
Subtitute…
y = kx + 2
-40 = k(14) + 2
-40 = 14k + 2
-40 - 2 = 14k
-42 = 14k
(-42)/14 = k
-3 = k

Ricky looked at his checking account balance regularly. The inequality statement compares the magnitude of his two lowest balances. What does the inequality statement show? |−300|>|−100| Select from the drop-down menus to correctly complete the statement. Even though −300 is Choose... than −100, a $100 debt is a Choose... debt than a $300 debt.
Answer:
1: less
2: lesser
Step-by-step explanation:
We can complete the statement as -
Even though |−300| is greater than |−100|, a $100 debt is a less debt than a $300 debt.
What is absolute value of a number?
The absolute value of a number is the magnitude of number. Absolute value describes the distance from zero that a number is on the number line, without considering direction.
We have a inequality statement that compares the magnitude of two lowest balances as -
|−300| > |−100|
For a number [x], such that [x] < 0, the absolute value would be -
v[a] = -x
So -
for x = |- 300| = 300
and
for x = |- 100| = 100
On comparing -
300 > 100
We can complete the statement as -
Even though |−300| is greater than |−100|, a $100 debt is a less debt than a $300 debt.
Therefore, we can complete the statement as -
Even though |−300| is greater than |−100|, a $100 debt is a less debt than a $300 debt.

factorize 18x-2x^3+9-x^2
Answer:
(3 - x)(3 + x)(2x + 1)
Step-by-step explanation:
18x - 2x³ + 9 - x² ( factor the first/second and third/fourth terms )
= 2x(9 - x²) + 1 (9 - x²) ← factor out (9 - x²) from each term
= (9 - x²(2x + 1) ← 9 - x² is a difference of squares a² - b² = (a - b)(a + b) )
= (3² - x²)(2x + 1)
= (3 - x)(3 + x)(2x + 1)

the length of a rectangle is four times it’s width if the perimeter of the rectangle is 70 yd find it length and width
Answer:
Step-by-step explanation:
Length = 4 * width
L = 4 * w
70 = Perimeter = 2*Length + 2* width = 2(4w) + 2w = 8w + 2w = 10w
so w=7 --> length is 28. Note that perimeter is 28+28+7+7 = 56 + 14 = 70
Then the area is 28 x 7 = 196 square inches

Answer:
The normal cost would be $11.50
The normal cost for an individual will be $11.50 per person.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Angie and her companions are making a beeline for the Ice sheet Levels snow park. They intend to buy the Glacial mass gathering bundle, which costs $76 for 8 individuals.
The cost of individuals will be given as,
⇒ $76 / 8
⇒ $9.50
That's $2 less per person than the normal cost for an individual. Then the normal cost is given as,
⇒ $9.50 + $2
⇒ $11.50
The typical expense for a singular will be $11.50 per individual.

A hotel has 30 floors with 40 rooms per floor. The rooms on one side of the hotel face the water, while rooms on the other side face a golf course. There is an extra charge for the rooms with a water view. The hotel manager wants to select 120 rooms and survey the registered guest in each of the selected rooms about his or her overall satisfaction with the property. The manager gets an SRS of rooms on the first floor with a water view and another SRS of rooms on the 30th floor with a golf course view.
Required:
a. Explain why choosing a stratified random sample might be preferable to an SRS in this case. What would you use as strata?
b. Why might a cluster sample be a simpler option? What would you use as clusters?
A) Choosing a stratified random sample might be preferable to an SRS because;
Stratified random sampling would divide the population into stratas but the
SRS would not do so. The strata would be the type of room namely those
with water view and those with golf view.
B) The reason why a cluster sample would be a simpler option is because;
It will divide the population into multiple clusters that makes it easier to
work with unlike the SRS that generalizes. The clusters would be each of
the 30 floors.
We are told that the manager wanted to select 120 rooms and carry out a survey on each registered guest by asking how satisfied they were with the hotel. He decided to use a sampling method called SRS which means Simple Random Sampling.
Simple random sampling is defined as a sampling method where individuals or objects are selected randomly from a population thereby given each person or object an equal chance of selection.
A) Stratified Random sampling is a method of sampling that divides the population into smaller groups known as objects/stata. In this case Stratified random sampling would be preferred to SRS because the hotel rooms are divided into two types namely those that can view the water and those that can view the golf course and as such the Stratified random sampling would divide the population but the SRS would not do so.
B) Cluster sampling is when the population is divided into multiple groups known for assessment. The reason why it would be a simpler option is because there are 30 floors and they can be classified as clusters and surveyed per floor.
