Answer:
10,665.64
Step-by-step explanation:
Exponential Functions:
y=ab^x
A= starting value = 19900
r=rate = 7.5%=0.075
Exponential Decay:
b=1-r=1-0.075=0.925
Write Exponential Function:
y=19900(0.925)^x
Plug in time for x:
y=19900(0.925)^8
y= 10665.6404317

It takes 1/8 of a roll of wrapping paper to completely cover all 6 sides of a small box that is shaped like a rectangular prism. The box has a volume of 10 cubic inches. Suppose the dimensions of the box are tripled. How many rolls of wrapping paper will it take to cover all 6 sides of the new box? What is the volume of the new box?
a. The number of rolls of wrapping paper it will take to cover the new box is 2¹/₄ rolls
b. The volume of the new rectangular box is 270 in³
Area of rectangular prism
Since the small box is a rectangular prism, its surface area, A = 2(lb + lh + bh) where
l = length, b = width and h = height.Now, when the dimensions are tripled, its new area is A' = 2(LB + LH + BH) where
L = 3l, B = 3b and H = 3h.So, A' = 2(LB + LH + BH)
= 2((3l)(3b) + (3l)(3h) + (3b)(3h))
= 2(3)(3)(lb + lh + bh)
= 18A
a. Number of rolls of wrapping paperThe number of rolls of wrapping paper it will take to cover the new box is 2¹/₄ rolls
Now, since we require 1/8 of a roll of wrapping paper to initially cover all 6 sides of the small box with dimensions, l,b and h. Then the number of rolls we require to cover the box when its dimensions are tripled are (since the area is proportional to the number of rolls)
N = 18 × 1/8
= 18/8
= 9/4
= 2¹/₄ rolls
The number of rolls of wrapping paper it will take to cover the new box is 2¹/₄ rolls
b. Volume of the new rectangular box
The volume of the new rectangular box is 270 in³
The volume of the rectangular box V = lbh where
l = length, b = width and h = heightWhen the dimensions are tripled, V' = LBH where
L = 3l, B = 3b and H = 3h.So, V' = LBH
= (3l)(3b)(3h)
= 27lbh
= 27V
Now since the initial volume of the rectangular box, V = 10 in³
V' = 27V
V' = 27 × 10 in³
V' = 270 in³
So, the volume of the new rectangular box is 270 in³

Ryan earns $5 for each small dog he walks and $8 for each large dog he walks. Today he walked 8 dogs and made a total of $49.
How many small dogs did Ryan walk?
Ryan walked
small dogs.
Answer:
He walked 5 small dogs and 3 large dogs.
Step-by-step explanation:
We'll represent the number of small dogs Ryan walked 'x,' and the number of large dogs Ryan walked '8-x.'
49 = 5x + 8(8-x)
x=5
8-5=3
Therefore, Ryan walked 5 small dogs and 3 large dogs.

We can use the Pythagorean Theorem to find the length of x. We know that the Pythagorean Theorem says that a²+b²=c². We can substitute the values 20, 15, and x into the equation.
20²+15²=x²
Simplify.
400+225=x²
Add.
625=x²
Find the square root of both sides to solve the equation.

Each of four circles has a radius of 4 inches. A larger circle has an area equal to the total area of the four smaller circles. What is the length of the radius, in inches, of the larger circle?
The radius of the larger circle is 8 inches
What is a circle?A circle is a round plane shape, whose circumference consists of points equidistant from a fixed point.
To calculate the radius of the larger circle, we use the formula below.
Formula:
A = 4A'............. Equation 1Where:
A = Area of the larger circleA' = Area of the smaller circle.But,
A = πR².............. Equation 2A' = πr²........... Equation 3Where:
R = Radius of the larger circler = radius of the smaller circle.Substitute equations 2 and 3 into equation 1
πR² = 4πr²R² = 4r²R = 2r .............. Equation 4Given:
r = 4 inchesSubstitute this value into equation 4
R = 2×4R = 8 inchesHence, The radius of the larger circle is 8 inches.

Say that Romania puts a tariff of 6% on its exports and 21% on its imports. If Romania has a trade deficit of (equivalent US dollars) $26. 76 billion and gained tariff revenue of $18. 9603 billion, how much are Romania’s imports worth? a. $62. 56 billion b. $64. 29 billion c. $76. 17 billion d. $97. 04 billion.
Answer:
c. $76.17 billion
Step-by-step explanation:
The relations between imports, exports, and tariffs can be described by ...
0.06E +0.21I = $18.9603 . . . . . . total tariff revenue
I -E = 26.76 . . . . . . . . . . . . . . . . trade deficit
Solving the second equation for E gives ...
E = I -26.76
Substituting into the first equation yields ...
0.06(I -26.76) +0.21I = 18.9603
0.27I = 18.9603 +1.6056 = 20.5659 . . . . add 1.6056 to both sides
I = 10.5659/0.27 = 76.17
Romania's imports are worth about $76.17 billion.

The exports are worth about $76.17 -26.76 = $49.41 billion.

so one thousand six hundred and seventy point five minus one thousand and thirteen point five equal to six hundred and fifty seven.
1670.5-1013.5 = $657
The budget for each meal of player is $54.75.
Divide $657 by $54.75. to get the number of players.

Solve the following system of equations.
Answer:
x= 0, y= -15
Step-by-step explanation:
Start by labelling the 2 given equations.
y= -2x -15 -----(1)
y= -15 +3x
y= 3x -15 -----(2)
Substitute (1) into (2):
-2x -15= 3x -15
3x +2x= -15 +15
5x= 0
Divide both sides by 5;
x= 0
Substitute x= 0 into (2):
y= 3(0) -15
y= -15
Answer:
Let eqn 1 be y = -2x -15
and Eqn2 be y-3x =-15
Substitute Eqn 1 into Eqn 2
where -2x-15-3x = -15
-5x = 0
X is 0
from Eqn1 the value of y Will be
-2(0) - 15
Value of y is -15
Therefore (X,y) = (0, -15)

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 it can also be interpreted as the initial value.In this problem, the cost of manufacturing H headbands is given by:

A line is drawn on a coordinate grid by the equation y = 1. Which of the following lines would represent a row perpendicular to it?
A. a line containing the point (5,2)
B. y = 1
C. x = 4
D. y = 3
Answer:
C
Step-by-step explanation:
In the Cartesian coordinate system, a line perpendicular to the line that's across the Y axis is a row across the X axis. You see Y=1 is the line across Y axis, so we need a row that's across the X axis. So C. X=4 is the ideal choice.
If a line is drawn on a coordinate grid by the equation y = 1 then x=4 would represent a row perpendicular to it.
What is Coordinate Geometry?A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.
A line is drawn on a coordinate grid by the equation y = 1.
The equation y = 1 represents a horizontal line on the coordinate grid, passing through all the points where y-coordinate is 1.
A line that is perpendicular to a horizontal line is a vertical line.
The vertical line x = 4 passes through all the points where x-coordinate is 4, and is perpendicular to the horizontal line y = 1.
Hence, if a line is drawn on a coordinate grid by the equation y = 1 then x=4 would represent a row perpendicular to it.
