Answer: 34.54feet
Step-by-step explanation:
Thw circumference of the pool will be calculated by using the formula:
= 2πr
where
π = 3.14
r = 5.5
Therefore, circumference = 2πr
= 2 × 3.14 × 5.5
= 34.54feet
Therefore, the circumference of the pool to the nearest hundredth is 34.54feet.
What steps to get the answer for -4x+7=11
Answer:
-4x=4
Step-by-step explanation:
-4x+7=11 subtract 7 add to the 11 answer-4x=4
Answer:
x=-1
Step-by-step explanation:
Move all terms not containing x to the right side of the equation.
Subtract 7 from both sides of the equation
-4x=11-7
Subtract 7 from 11
-4x=4
Divide each term and simplify
x=-1.

Calculate the distance between Points A and B.
A.4.5
B.7.1
C.7.8
D.9.2
Answer:
7.8 units separate the points A and B.
Step-by-step explanation:
Going from B to A, x increases by 6 (this is the horizontal side of the triangle formed by vertices A and B), and y increases by 5. Applying the Pythagorean Theorem, we get
d = √(6² + 5²), or √(61, which is approximately 7.8, the desired distance.

Answer:
28 cubs
Step-by-step explanation:
Since one and a half bear produces one and a half cub, then 6 bears will produce 6 cubs in one and a half days.
We need to find 7 days, though but we have the rate for six bears for 1.5 days which 6 bears one a half day.
What is the rate for a day?
6/1.5 =
6 bears produce 4 cubs a day.
Now just do 4 x 7
4 x 7 = 28
Therefore, 6 bears produce 28 cubs in 7 days.
Mark and Tony have a total of 121 baseball cards. Tony has 5 more than three times Mark's amount. How many cards does Mark have?
Answer:
29
Step-by-step explanation:
make Mark x and Tony 3x + 5
X+3x+5=121
The number of baseball cards in between Tony and Mark is a linear equation, where Mark has 29 cards.
What is a linear equation?A linear equation is an equation where the variable has the highest power of one. A linear equation may be consists of multiple variables.
Let, Mark has x cards.
Therefore, Tony has (3 × x + 5) cards = (3x + 5) cards.
Given, x+ 3x + 5 = 121
⇒ 4x +5 = 121
⇒ 4x = 121 - 5
⇒ 4x = 116
⇒ x = 116 / 4
⇒ x = 29
Hence, Mark has 29 cards.

The perimeter of a rectangle is the same as the
perimeter of a square. If the area of this rectangle
is x^2 + 4x – 21 and the side lengths are integers,
find:
a. the perimeter of the rectangle
b. the area of the square
Answer:
a. 20
b. 25
Step-by-step explanation:
Let find the side lengths of the rectangle,
We can complete the square.
[tex] {x}^{2} + 4x - 21[/tex]
[tex] {x}^{2} + 4x = 21[/tex]
[tex] {x}^{2} + 4x + 4 = 25[/tex]
[tex](x + 2) {}^{2} = 25[/tex]
[tex](x + 2) = 5[/tex]
[tex]x = - 7[/tex]
or
[tex](x + 7)[/tex]
[tex]x = 3[/tex]
or
[tex](x - 3)[/tex]
This means the perimeter of is
2 times -7 equal 14
2 times 3 equal 6
14+6=20.
The side lengths of the square is equal so each side length will measure 5.

Find the number that is exactly half way between -4 and 10
Answer:
7 as a halfway of a line
3 if you were using points on a graph
Step-by-step explanation:
10--4/2=7
use midpoint formula for 3
The number that is exactly halfway between -4 and 10 is 3
The distance between two point is the amount of length between the two points.
Midpoint of -4 and 10 is 10 - (-4) gives 10 + 4
The distance between -4 and 10 is 14 units
Halfway of the length between -4 and 10 is 14 /2 (7)
The number that is exactly halfway between -4 and 10 = -4 + 7 or 10 - 7 = 3
The number that is exactly halfway between -4 and 10 is 3

Margo wants new carpet and a new wallpaper border for her bedroom. The room is 5.7 yards long and 6 7 8 yards wide. About how many square yards of carpet will she need? About how many yards of wallpaper border will she need?
Answer:
39.19 yards^2
25.15 yards
Step-by-step explanation:
To determine the squares square yards of carpet needed, we have to determine the area of the room
The room is shaped like a rectangle
area of a rectangle = length x breadth
5.7 x 6 7/8
To multiply, convert 6 7/8 to a decimal
to do this, divide 7 by 8. Add the value gotten to 6
5.7 x 6.875 =39.19 yards^2
To determine the yards needed for the border, calculate the perimeter of the room
Perimeter = 2 x (length + breadth)
2 x(5.7 + 6.875) = 25.15 yards

A process is stationary if: a. any collection of random variables in a sequence is taken and shifted ahead by h time periods, the joint probability distribution remains unchanged. b. there is serial correlation between the error terms of successive time periods and the explanatory variables and the error terms have positive covariance. c. there is no serial correlation between the error terms of successive time periods and the explanatory variables and the error terms have positive covariance. d. any collection of random variables in a sequence is taken and shifted ahead by h time periods; the joint probability distribution changes.
Answer:
B.any collection of random variables in a sequence is taken and shifted ahead by htime periods, the joint probability distribution remains unchanged
Step-by-step explanation:
In most of the time series techniques , there is usually a common assumption that data are stationary. A stationary process can be regarded as one that has properties such as variance mean, variance as well as autocorrelation structure not changed over time. The properties is independent as regards the time the series is observed.
✓ Time series that has trends or seasonality cannot be regarded as stationary, because the value of the time series which exist in different times will be affected by the trend and seasonality.
✓A white noise series can be regarded as stationary because the time you observe it does not matter, it will always look much the same at all point in time.
✓ It should be noted that process is stationary if any collection of random variables in a sequence is taken and shifted ahead by htime periods, the joint probability distribution remains unchanged

a company makes $10 000 in 2017. The projection of profit increase is fixed 40% from the previous year. Predict the company profit in 2019.
Answer:
19600
Step-by-step explanation:
For every year the profit increases by 40% so to figure out the profit from 2017 to 2018 you do 10,000*1.4 to and get 14,000. To get 2019's profit you do the same process, but use 2018's profit of 14,000 instead of 2017's profit to get 19,600.
Find the simple interest. Round to the nearest
cent if necessary.
$1450, 32%, 3 months
Answer: $116
Step-by-step explanation:
Simple interest is calculated using the formula = PRT
where,
P = principal = $1450
R = rate = 32%
T = time = 3 months = 3/12 = 1/4 = 0.25
Interest = PRT
= 1450 × 32% × 0.25
= 1450 × 0.32 × 0.25
= $116
The simple interest is $116

The formula for determining the pressure, p, exerted
on an object at a depth, h, below the surface of a
liquid is p = s + dgh, where s is the atmospheric
pressure, d is the density of the liquid, and g is the
acceleration due to gravity. Which formula
represents h in terms of p, s, d, and g?
Answer:
p = s + dgh
p - s = dgh
(p - s) / dg = h
Answer = h= p-s/dg
The formula that represents the height "h" in terms of p, s, d, and g is expressed as (p - s)/dg
Given the formula for determining the pressure, p, exerted on an object at a depth, h, below the surface of a liquid expressed as p = s + dgh where:
s is the atmospheric pressure,
d is the density of the liquid, and;
g is the acceleration due to gravity
We are to make h the subject of the formula;
p = s + dgh
Subtract s from both sides
p - s = dgh
dgh = p - s
Divide both sides by dg
dgh/dg = (p - s)/dg
h = (p - s)/dg
Hence the formula that represents the height "h" in terms of p, s, d, and g is expressed as (p - s)/dg

4x+5y=60. what is the x and y intercepts? show work pls!!
Answer: (4,5)
Because I don't know another way I can solve
Step-by-step explanation:
Answer:
x-intercept: (15, 0)
y-intercept: (0, 12)
Step-by-step explanation:
1.) convert the equation to y=mx+b format
4x + 5y= 60
5y = -4x + 60
y = -4/5x + 12
2.) Now we know that "b" in the equation is the y-intercept. 12 is b so the y-intercept is 12.
3.) To find x intercept we will plug in y=0.
0 = -4/5x + 12
-12 = -4/5x
15 = x
