Answer:
5499.38
Step-by-step explanation:
We can model the price of a given car in this scenario with the formula [tex]P=I\cdot\frac{1}{2}^t[/tex], where P is the current price of the car, I is the initial price, and t is the amount of time in decades that the car has been around. Plugging 43995 in for I and 3 in for t, we get:
[tex]P=43995\cdot\frac{1}{2}^3=43995\cdot\frac{1}{8}=5499.375\approx5499.38[/tex]

A ladybug crawls around the outside of a rectangle that measures 7.5 cm by 8.5 cm. The ladybug stays exactly 3.9 cm from the rectangle at all times to form a larger figure. What is the area of the new rectangle bound by the path of the bug?
Answer:
185.64 [tex]cm^{2}[/tex]
Step-by-step explanation:
Width =7.5+3.9*2 = 15.3 cm
Length = 8.5+3.9*2=16.3 cm
Big Area = 15.3*16.3 = 249.39 [tex]cm^{2}[/tex]
Small Area = 7.5*8.5 = 63.75 1 [tex]cm^{2}[/tex]
area bounded by the path of the bug = 249.39-63.75 = 185.64 [tex]cm^{2}[/tex]

Answer:
4.5
Step-by-step explanation:
∛100 = ?
100 = 2 x 2 x 5 x 5
∛100
= ∛ ( 2 x 2 x 5 x 5 )
= 4.642
4.642 ~ 4.5
The approximation 4.642 can also be written as 4.5
Therefore,
∛100 = 4.5
What is the value of x? Midsegments of triangles
Hi how u doin ?
[tex] \frac{16}{x + 4} = \frac{1}{2} \\ [/tex]
inverse both sides
[tex] \frac{x + 4}{16} = \frac{2}{1} \\ [/tex]
Multiply both sides by 16
[tex]16 \times \frac{x + 4}{16} = 16 \times 2 \\ [/tex]
[tex]x + 4 = 32[/tex]
Subtract both sides 4
[tex]x + 4 - 4 = 32 - 4[/tex]
[tex]x = 28[/tex]
There u go..... Have a great day ❤
this is just and addition to the great posting below, just supplementing.
keeping in mind that the midsegment of a triangle is half the length of the parallel base/side, Check the picture below.
please help k12 math 8th grade math pictures below will give brainliest if correct
Step-by-step explanation:
For first picture,Here Given,
x = White rectangular box
-x = Black rectangular box
1 = White square
-1 = Black square
Condition,
No. of White rectangular boxes = 5
(On putting the value x) = 5xNo. of Black rectangular boxes = 8
(On putting the value -x) = -8xNo. of White square boxes = 9
(On putting the value 1) = 9No. of Black square boxes = 4
(On putting the value -1) = -4Therefore Simplification,
5x + (-8x) + 9 + (-4)
= - 3x + 5 (Ans) (option D)
For second picture,Here Given,
x = White rectangular box
-x = Black rectangular box
1 = White square
-1 = Black square
Condition,
Left side,
No. of White rectangular boxes = 7
(On putting the value x) = 7xNo. of Black rectangular boxes = 3
(On putting the value -x) = -3xNo. of White square boxes = 1
(On putting the value 1) = 1No. of Black square boxes = 2
(On putting the value -1) = -2Right side,
No. of White rectangular boxes = 1
(On putting the value x) = xNo. of Black rectangular boxes = 3
(On putting the value -x) = -3xNo. of White square boxes = 8
(On putting the value 1) = 8No. of Black square boxes = 3
(On putting the value -1) = -3Therefore Equation,
7x - 3x + 1 - 2 = x - 3x + 8 - 3
=> 6x = 6
=> x = 1 (Ans) (option B)
For third picture,Given values,
a = 13, b = 3, c = 6
Solution,
[tex](26 - a) + \frac{ - 2bc}{2} + \sqrt{289} [/tex]
(On putting values of a, b and c)
[tex] = (26 - 13) + \frac{ - 2 \times 3 \times 6}{2} + \sqrt{289} [/tex]
= 13 + (-18) + 17
= 12 (Ans) (option A)
For fourth picture,Given values,
x = 14, y = 5, z = 6
Solution,
[tex] (25 - x) + \frac{4yz}{2} [/tex]
(On putting values of x, y and z)
[tex] = (25 - 14) + \frac{4 \times 5 \times 6}{2} [/tex]
= 11 + 60
= 71 (Ans)

Find the volume of the oblique rectangular prism with length 8 cm, width 6 cm, and height 7 cm.
Answer:
336 cm³
Step-by-step explanation:
As long as the height is measured perpendicular to the base, the volume formula applies.
V = LWH
V = (8 cm)(6 cm)(7 cm) = 336 cm³ . . . . volume of the prism
Every year, the value of an antique vase appreciates by 20% of it's value in the previous year if the value of case was 180000 in 2012, find it's value in 2010.
guys I am giving you 100 POINTS!!!no cheating and I need answer that is 125000 and send me with solution?
and guys I need solution easy mean like percentage decreased or increased that is enough explanation for you all of you and if anybody who is free and can give answer right now so please answer me? i will mark you brainlest ok bye
[tex]\large{\rm{\underline{\underline{Answer:}}}}[/tex]
In Direct formula method:
If the rate of appreciation r, the initial value I, the final value V, and the period of appreciation n, the formula for appreciation is given by:
V = I(1 + r)ⁿ
In our case, we need to work out the value of n which is number of years in between 2010 and 2012.
So, n = 2012 - 2010 = 2 years
Put the values we have:
⇛180000 = I(1.20)² [ Increases 20% every year ]
⇛180000 = 1.44I
⇛I = 180000/1.44
⇛I = 125000
So, in 2010, the value of the vase was $125000

Question 2 (Essay Worth 10 points)
(07.02 MC)
An equation is shown below:
3(2x - 7) = 3
Part A: How many solutions does this equation have? (4 points)
Part B: What are the solutions to this equation? Show your work.
Plzzzzzz help
Answer:
Part A: 1 solution
Part B:
3(2x-7)=3
6x-21=3
+21 +21
6x=24
/6 /6
x=4
Step-by-step explanation:
First you distribute 3(2x-7)=3 to 6x-21=3. Next you do inverse operations by adding 21 to both sides of the equation to get 6x=24. Finally you divide both sides by 6 to get x=4
∫[tex]\frac{cosxdx}{\sqrt{1+sin^{2}x } }[/tex]
Substitute sin(x) = tan(t) and cos(x) dx = sec²(t) dt. We want this change of variable to be reversible, so let's assume bot x and t are bounded between 0 and π/2.
Then we have
[tex]\displaystyle \int \frac{\cos(x)}{\sqrt{1 + \sin^2(x)}} \, dx = \int \frac{\sec^2(t)}{\sqrt{1 + \tan^2(t)}} \, dt[/tex]
Recall the Pythagorean identity,
1 + tan²(t) = sec²(t)
Then
√(1 + tan²(t)) = √(sec²(t)) = sec(t)
and the integral reduces to
[tex]\displaystyle \int \frac{\sec^2(t)}{\sqrt{1 + \tan^2(t)}} \, dt = \int \frac{\sec^2(t)}{\sec(t)} \, dt = \int \sec(t) \, dt = \ln|\sec(t)+\tan(t)| + C[/tex]
Change the variable back to x, so the antiderivative is
[tex]\displaystyle \int \frac{\cos(x)}{\sqrt{1 + \sin^2(x)}} \, dx = \ln \left|\sec\left(\tan^{-1}(\sin(x))\right) + \tan\left(\tan^{-1}(\sin(x))\right) \right| + C [/tex]
[tex]\displaystyle \int \frac{\cos(x)}{\sqrt{1 + \sin^2(x)}} \, dx = \boxed{\ln \left|\sqrt{1+\sin^2(x)} + \sin(x) \right| + C} [/tex]
If a total of 1100 square centimeters of material is to be used to make a box with a square base and an open top, find the largest possible volume of such a box.
Answer:
Step-by-step explanation:
Let x = base side length
y = side height
volume V = x²y
y = V/x²
surface area
A = x² + 4xy
A = x² + 4x(V/x²)
A = x² + 4V/x
Solving for volume
V = (A - x²)(x/4)
V = ¼(Ax - x³)
a maximum will occur when the derivative equals zero
V' = ¼(A - 3x²)
0 = ¼(A - 3x²)
0 = A - 3x²
3x² = A
3x² = 1100
x² = (1100 / 3)
x = √(1100/3)
V = (A - x²)(x/4)
V = (1100 - √(1100/3))²(√(1100/3)/4)
V = 3,510.56606...
V = 3510.6 cm³
The box height will be half of the base side length.
y = ½√(1100/3)

Jennifer has 3 ¼ cups of dough to make cookies. If she uses 5/16 cup of dough for each cookie, how many whole dumplings can she make?
Answer:
Step-by-step explanation:
3 ¼ / 5/16
3 ¼ = 13/4
to divide by a fraction, multiply by the reciprocal of the fraction
13/4•16/5 = (13•16) / (4•5) = 208 / 20 = 10.4
10 whole cookies but NO dumplings
