Answer: [tex]56,900\left( 0.919\right)^x[/tex]
Step-by-step explanation:
Given
Marcos purchased a sailboat for [tex]\$56,900[/tex]
Each year the boat will decrease in value by [tex]8.1\%[/tex]
After 1 year it is
[tex]\Rightarrow 56,900-56,900\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\\[/tex]
after another year it becomes
[tex]\Rightarrow 56,900\left( 1-0.081\right)-56,900\left( 1-0.081\right)\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\cdot \left( 1-0.081\right)\\\Rightarrow 56,900\left( 1-0.081\right)^2[/tex]
After [tex]x[/tex] years it is
[tex]\Rightarrow 56,900\left( 1-0.081\right)^x[/tex]
[tex]\Rightarrow 56,900\left( 0.919\right)^x[/tex]
Construct a street that has an x-intercept of 6 and a slope of 4. what is the y-intercept?
Answer: CAN U MARK BRAINLIST!!!!! You've probably already seen the basic method for graphing straight lines; namely, make a T-chart, plot some points, put your ruler against them, and draw the line. But the "nice" form of a straight line's equation (being the slope-intercept form, y = mx + b) can make graphing even simpler and faster.
Given two points (x1, y1) and (x2, y2), the formula for the slope of the straight line going through these two points is:
\small{ m = \dfrac{y_1 - y_2}{x_1 - x_2} }m=

...where the subscripts merely indicate that we have a "first" point (whose coordinates are subscripted with a "1") and a "second" point (whose coordinates are subscripted with a "2"); that is, the subscripts indicate nothing more than the fact that we have two points that we're working with. Note that which point we pick as the "first" point is irrelevant; if we pick the other point to be "first", the subtractions will be reversed, but we'll still get the exact same value for the slope:
\small{ m = \dfrac{y_2 - y_1}{x_2 - x_1} }m=

Answer:
110.94
Step-by-step explanation:
Surface area is the area of each side of the shape added together. So in this situation, it would be the area of a side, multiplied by 6, because a square has six sides.
To find the area, it's length x width. You're given the length and width, which both are 4.3 mm.
4.3 x 4.3 = 18.49
With this new number, you're gonna multiply it by 6. And the total will be 110.94 mm. :)
If k = 2, what is the value of k3 - (k-10)+4k ?
Answer:
24
Step-by-step explanation:
The given expression is k^3 - (10-k) +4k
Substitute the numerical value of k=2 in the above expression
2^3-(2-10)+4*2=8+8+8=24
The value of the given expression is 24
Answer:
24
Step-by-step explanation:
k³ - (k - 10) + 4k
= 2³ - (2 - 10) + 4(2)
= 8 - (-8) + 8
= 16 + 8
= 24

How many unit fraction cubes fit into the first layer of the rectangular prism?
Answer:
33 cubes
Step-by-step explanation:
The first layer is 5 1/2 x 3 = 16 1/2
Since each cube we're using to fill it is 1/2 unit long/wide, it's easiest to convert 16 1/2 into halves...16 = 32 halves + 1/2 = 33
is it possible to construct a triangle with the given lengths? 17, 37, 53
Answer:
Yes
Step-by-step explanation:
In any triangle, the sum of any two sides must be larger than the third side. To test this, we only actually need to pick the two shorter sides. In this case, the following inequality is true:
[tex]17+37>53,\\54>53,\\\text{True}\:\checkmark[/tex]

A cottage has a gable roof. To the nearest foot, how wide is the cottage?A. 12 ftB. 24 ftC. 35 ftD. 70 ft
Answer: the answer is B: 24ft
Step-by-step explanation: To find how wide the triangle is identify your angles. You have a right angle which is equal to 90° and an angle that measures 46°. Add up both of these angles and you'll get 136°. A triangle can only have three angles that add up to 180. So subtract 180 and 136 you get 44. Multiply the hypotenuse by sin(46) to get the length of the side facing the opposite way of the angle that measures 44°. You will get 11.8 which is about 12. The other triangle is a congruent triangle meaning that it's angles and sides are the same. Add both 12's up and you have 24ft as your width for the cottage.

The sum of 2 numbers is 21.
The second number is 6 times the first number.
Work out the two numbers.
Answer:
both numbers are 18 and 3
Step-by-step explanation:
Answer:
3 and 18.
Step-by-step explanation:
Let the numbers be x and 21-x, then:
21-x = 6x
6x = 21 - x
7x = 21
x = 3
The 2 numbers are 3 and 18.
1/3 of 3/5= ____?
pls i need help lol
Answer:
[tex]\frac{1}{5}[/tex] or 0.2
Step-by-step explanation:
Multiply 1/3 times 3/5
To multiply fractions, multiply numerators by numerators, and denominators by denomintors.
1 x 3 = 3
3 x 5 = 15
So, you get 3/15 = 1/5

Think About the Process In the diagram, m∠1=(117−y)°, m∠2=25°, and m∠3=(x+46)°. Write an equation to solve for x and an equation to solve for y. Find the values of x and y.

2
3
(The figure is not shown to scale.)
Write an equation to solve for x and an equation to solve for y. Choose the correct answer below.
A.
25+x+46=90 and 117−y=90
B.
x+46=90 and 25+117−y=90
C.
25+x+46=90 and 117−y=180
D.
25+x+46=180 and 117−y=90
Answer:
A
Step-by-step explanation:
∠1 is a right angle
Right angles have a measure of 90°
If ∠1 = 117 - y
Then 117 - y = 90
∠2 and ∠3 create a right angle
Like stated previously right angles have measures of 90°
This means that ∠2 + ∠3 = 90
So if ∠2 = 25 and ∠3 = x + 46
Then 25 + x + 46 = 90
The equations created correspond with the answer choice A
Therefore A is the correct answer

A plumber has been working at 4 customer sites. He has completed 1/4, 50%, 12.5%, 3/4 and of his work at the sites. Which list shows the work completed at the sites, in order from greatest to least? 1. 12.5%, 1/4, 50%, 3/4 2. 3/4, 50%, 1/4, 12.5% 3. 3/4, 12.5%, 1/4, 50% 4. 1/4, 50%, 3/4, 12.5%
Answer:
2. 3/4, 50%, 1/4, 12.5%
Step-by-step explanation:
Work completed at the 4 sites = 1/4, 50%, 12.5%, 3/4
1/4 = 0.25
50%
= 50/100
= 0.5
12.5%
= 12.5/100
= 0.125
3/4
= 0.75
in order from greatest to least?
3/4, 50%, 1/4, 12.5%
1. 12.5%, 1/4, 50%, 3/4
2. 3/4, 50%, 1/4, 12.5%
3. 3/4, 12.5%, 1/4, 50%
4. 1/4, 50%, 3/4, 12.5%

The diameter of a circle measures 22 cm. What is the circumference of the circle?
Use 3.14 for at, and do not round your answer. Be sure to include the correct unit in your answer.
Answer:
Step-by-step explanation:the circumference of a circle is found by multiplying the diameter by pi
Circumference = 22cm x 3.14 = 69.08 cm
Answer:
69.08 cm
Step-by-step explanation:
The circumference of a circle can be found using the following formula:
where d is the diameter. We know the diameter of the circle is 22 centimeters. Substitute the value in for d.
We also know we are using 3.14 for pi. Substitute it in for pi.
Multiply.
The circumference of the circle is 69.08 centimeters.
