In 2008, there were 285 cell phone subscribers in the small town of Berrydale. The number of subscribers increased by 75% per year after 2008. How many cell phone subscribers were in Berrydale in 2017?
Answer:
Step-by-step explanation:
[tex]F=I(1.75^t)\\ \\ F=285(1.75)^{y-2008}\\ \\ F=285(1.75)^{2017-2008}\\ \\ F=285(1.75)^9\\ \\ F=43871.99\\ \\ F\approx 43872[/tex]

what is distance between C(−5,−2) and D(0,−4)
Answer:
[tex]\displaystyle d = \sqrt{29}[/tex]
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Coordinates (x, y)Algebra II
Distance formula: [tex]\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]Step-by-step explanation:
Step 1: Define
Point C(-5, -2)
Point D(0, -4)
Step 2: Find distance d
Simply plug in the 2 coordinates into the distance formula to find distance d
Substitute in points [Distance Formula]: [tex]\displaystyle d = \sqrt{(0+5)^2+(-4+2)^2}[/tex][√Radical] (Parenthesis) Add: [tex]\displaystyle d = \sqrt{(5)^2+(-2)^2}[/tex][√Radical] Evaluate exponents: [tex]\displaystyle d = \sqrt{25+4}[/tex][√Radical] Add: [tex]\displaystyle d = \sqrt{29}[/tex]17. If x is a real number such that x3 = 729,
then x2 + x = ?
A. 738
B. 732
C. 90
D. 84
E. 12
Answer:
C. 90
Step-by-step explanation:
If x^3 = 729, x = 9.
Then, plug that into x^2 + x
9 ^ 2 + 9 = 81 + 9 = 90
Jaimie is practicing for the long jump. Each week she makes 10 jumps and after each jump she records the distance, in meters, she reaches with each jump. Her results for this week are represented in the table below. Jump 1 2 3 4 5 6 7 8 9 10 Distance (m) 5.1 5.3 5.4 5.2 5.5 5.4 5.2 5.3 5.5 3.5 Jaimie then reviews her results and determines the mean and standard deviation so that she can compare her results from this week to her results from the previous week. Jaimie felt the 10th jump was not reflective of her ability because she stumbled before making the jump and decided to remove the 10th jump from her data set. Determine whether each statement describes the change that will occur to the mean and standard deviation from this week's results when Jaimie removes the 10th jump from her data set. Select Yes or No for each statement. Yes No Removing the 10th jump from her data set will cause her average jump distance to increase. Removing the 10th jump from her data set will cause her average jump distance to decrease. The standard deviation will increase because the jump distances will be more spread out. The standard deviation will decrease because the jump distances will be more clustered together.
Answer:
mean=(5.1 +5.3+ 5.4 +5.2+ 5.5 +5.4+ 5.2 +5.3 +5.5+ 3.5)/10=51.4/10=5.14

If the perimeter of a parallelogram is 140 m, the distance between a pair of opposite sides is 7 metres
and its area is 210 sq. m. find the length of the two adjacent sides of the parallelogram
Answer:
10 m and 60 m.
Step-by-step explanation:
Perimeter = 140 m
Area = 210 [tex]m^{2}[/tex]
Distance between pair of opposite sides = height of the parallelogram = 7 m
Area of parallelogram = [tex]\frac{1}{2}[/tex] x base x height
210 = [tex]\frac{1}{2}[/tex] x base x 7
420 = 7 x base
base = [tex]\frac{420}{7}[/tex]
= 60 m
The base of the parallelogram is 60 m, which is equal to the length of the opposite side.
Perimeter = 2(a + b)
140 = 2 (a + 60)
140 = 2a + 120
2a = 140 - 120
2a = 20
a = 10 m
Thus, the length of two adjacent sides of the parallelogram are; 10 m and 60 m.

Keisha's cat had kittens. The line plot below shows the weight, in pounds, of each kitten.
What is the total weight of all the kittens that weighed 3/8
pound?
Answer:
the answer would be 1 7/8
Step-by-step explanation:
first you would count up the number of kittens that weighted 3/8 of a pound. You should have the number of 5, next you would multiply 5 × 3/8= 1.875 (as a decimal). Then you would convert that number into a mixed number (fraction) because all the answers are in mixed number form. You should get 1 7/8 because:
(1875÷125)(1000÷125) = 158 when reduced to the simplest form. As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 18751000 is also equal to 1 7/8 when expressed as a mixed number.
I hope this helps!
2a+b=5 and 6y+4y=48 show that 20a+10b has a greater value than 3x+2y
Answer:
Step-by-step explanation:
There is an error in the question. 6x+4y = 48
Multiply first equation by 10:
20x+10y = 50
Divide second equation by 2:
3x+2y = 24
50>24, so 20x+10y > 3x+2y

Solve the equation -2x + 9 - 3x= -5x + 3
Answer:
There are no solutions
Step-by-step explanation:
Answer:
no real solutions
Step-by-step explanation:
-2x + 9 - 3x = -5x + 3
First, combine like terms on each side.
-2x - 3x + 9 = -5x + 3
-5x + 9 = -5x + 3
Continue to combine the like terms from both sides.
0 = -6
The above expression is not true, therefore, there are no real solutions.

Solution (x, y) i dont understand it
Answer:
(3, 3)
Step-by-step explanation:
I guess you're looking for a point that satisfies 2 functions (red and blue). That point is an intersection of these two functions, hence (3,3)
Answer:
[tex]\boxed{\boxed{(x,y)=(3,3)}}[/tex]
Step-by-step explanation:
to understand thisyou need to know about:system of linear equationgraphing system of linear equationtips and formulas:when we have two linear equation to find the value of x and y is called the system of linear equationwhen we have graph, the solutions of system of linear equation are the coordinates of two lines cross togetherlet's solve:since you can see at "tips and formulas" what linear equation is and what the solutions are when you have graph
if you see the graph attentively, you can see that the blue line and the red line cross together at (3,3) coordinates
therefore
the solution of the system of linear equation is
(x,y)=(3,3)
