Answer:
$18,112.45 (nearest cent)
Step-by-step explanation:
Let y = value of the boat
Let x = the number of years
If the boat depreciates in value by 15% each year, then each year that goes by, it is worth 85% of the previous year's value (since 100 - 15 = 85)
85% = 85/100 = 0.85
Therefore, the equation is: [tex]y = 92000 \times 0.85^x[/tex]
So, when x = 10:
[tex]\implies y = 92000 \times 0.85^{10}=18112.45[/tex]
Mike wrote down a number on a piece of paper and hid it from his friends. He rounded his number to different places and his friends had to guess what the number was.
First, Mike rounded his number to the nearest ten.
Then, he rounded his number to the nearest hundred.
Last, he rounded his number to the nearest thousand.
All three times, the rounded number had the same value.
Which of these could be his number?

The solution to the system of equations will be (x, y) = (10,20).
What is the equation?In a mathematical equation, two expressions—which may or may not include variables or integers—are declared to be equal. The main motivations for the development of mathematics have been attempts to methodically address the underlying issues with equations.
It is given that, the equations are y=2x and y=3x-10.
Y=2x. . . . (1)
Y=3x-10. . . . (2)
put the value of y in 1 eq in 2 eq in order to find the value of x.
y= 3x - 10
2x = 3x - 10
x = 10
Put the value of x in 1 eq in order to get the value of y,
y = 2x
y = 2 × 10
y = 20
Pair formed
(x , y) = (10,20)
Thus, the solution to the system of equations will be (x, y) = (10,20).

Answer:
Area is 220 cm²
Step-by-step explanation:
Firstly divide the polygon into rectangle and triangle
For rectangle area
Area = A = L × W = 11 × 18 = 198 cm²
For triangle
Area = A = 1/2 bh = 1/2 × (15-11) × (18-7) = 1/2 × 4 ×11 = 44/2 = 22 cm²
Add them
198 + 22 = 220cm²

Determine the area of the composite figure.
Answer:
Area = 142.5 square inches
Step-by-step explanation:
So your shape is kind of a little house. The bottom part is a rectangle 9 × 9.5. The area of the rectangle is
Area = length×width
= 9 × 9.5
= 85.5
The "roof" of the little house is a triangle. The area of a triangle is 1/2×base×height
Now, the base of the "roof" is the same as the floor of the house, 9.5 inches.
The height of the whole thing is 21 inches. If we take away the rectangle's wall-height, we'll get the height of the "roof".
Roof height= 21 - 9
= 12 inches
Area_roof
=1/2 × base × height
=1/2 × 9.5 × 12
= 57 square inches
Total area is bottom plus roof (the rectangle and the triangle)
Total Area
= 85.5 + 57
= 142.5 sq in

A researcher measures the amount of food consumed by each dog in her lab. She finds that the mean amount eaten by the 10 dogs is 14 oz. The sum of squared deviations is 220. What is the variance for this data set
Using statistical concepts, it is found that the variance for this data set is of 22 oz squared.
What are the mean and the variance of a data-set?The mean of a data-set is given by the sum of all observations divided by the number of observations.The variance of a data-set is given by the sum of the differences squared between each observation and the mean, divided by the number of values.
From the second bullet point, the variance can also be interpreted as the sum of squared deviations divided by the sample size.
In this problem, the sum of squared deviations is 220 and the sample size is 10, hence, the variance for this data set is of 22 oz squared.

Answer: B) The coordinate of L is (3,-2).
Step-by-step explanation:
Given that L is the midpoint of JK, we can apply the following equation to obtain the coordinates of point L:
L=(5+1/2, 3-7/2)
As a result of resolving this, we obtain
L=(6/2, -4/2)
L=(3,-2)
Therefore the answer is (3,-2)

Use intercepts to graph the linear equation -4x+3y=-30 .
Answer:
See below
Step-by-step explanation:
Y-intercept
-4x + 3y = -30
-4(0) + 3y = -30
3y = -30
y = -10
(0, -10)
X-intercept
-4x + 3y = -30
-4x + 3(0) = -30
-4x = -30
x = 15/2
x = 7.5
(7.5,0)
After plotting the intercepts, connect them with a line to get your equation

Please help me on 4,5,6, and 7.
Answer:
4. m<3 = 120
5. m<4 = 13
6. m<2 = 70
7. m<1 = 115
Step-by-step explanation:
4. m<3 = 120, this is because it is the same as m<1 due to vertical (congruent) angles
5. m<4 = 13, this is because it is the same as m<2 due to vertical (congruent) angles
6. m<2 = 70, this is because m<2 and m<3 are supplementary (adding up to 180) so we would subtract 180 - 110 (aka m<3) = 70 (aka m<2)
7. m<1 = 115, this is because m<1 and m<4 are supplementary (adding up to 180) so we would subtract 180 - 65 (aka m<4) = 115 (aka m<1)
Which expressions are equivalent to 4d+6+2d
(Choice A) 2(3d+3)
(Choice B) 6(d+6)
(Choice C) (3d+3)+(3d+3)
Answer:
(Choice A) 2(3d+3) & (Choice C) (3d+3)+(3d+3)
Step-by-step explanation:
[tex]4D + 6 + 2D = 6D + 6 = 2(3D + 3)[/tex] <--- A is correct
[tex]4D + 6 + 2D = 6D + 6 = 6(D +1)[/tex] < --- B is NOT correct
[tex]4D + 6 + 2D = 6D + 6 = 3d + 3d + 3 + 3 = (3d + 3)+(3d +3)[/tex] by associative and commutative properties
so C is correct
A and C are both correct.
Answer:
Choices A and C
Step-by-step explanation:
Start by simplifying the original expression.
4d+6+2d
Combine like terms
6d+6
Now, we can check each expression to see if it is equivalent to 6d+6
Choice A:
2(3d+3)
Distribute the 2
2(3d)+2(3)
6d+6 --> It is equivalent!
Choice B:
6(d+6)
Distribute the 6
6(d)+6(6)
6d+36 --> No, it is not equivalent
Choice C
(3d+3)+(3d+3)
The parentheses aren't necessary so we can take them out.
3d+3+3d+3
Combine like terms
6d+6 --> It is equivalent!
Kay started a chess club, and for a while she was the only member. She planned to have each member find two new members each month. By the end of the first month, she had found two new members. If her plan is carried out, how many members will the club have at the end of 6 months
Answer:
127
Step-by-step explanation:
The sum of 7 terms of the series 1 +2 +4 +... with first term 1 and common ratio 2 is given by ...
Sn = a1 × (r^n -1)/(r -1) . . . . . . first term a1, common ratio r
S7 = 1 × (2^7 -1)/(2 -1) = (128 -1)/1 = 127
At the end of 6 months, the club will have 127 members.
