Dan bought a new computer for $900. Each year, the value of the computer decreased by 25% of the previous year's value. At this rate, what can Dan expect the approximate value of the computer to be after 8 years?
Answer:
$90
Step-by-step explanation:
Given data
Price= $900
Rate= 25%
Time= 8 years
Let us apply the compounding formula
A= P(1-r)^t >>>>note that the negative sign is because of the depreciation
substitute
A= 900(1-0.25)^8
A= 900(0.75)^8
A= 900*0.100
A= $90
Hence the value of the car after 8 years will be $90

Central Fencing has been hired to fence the perimeter of a rectangular field. The length of the field is 42 - W feet, where W is the width of the field, and the area of the field must be more than 432 square feet. Find the bounds on the width of the field.
Answer:
10.3 is the width
Step-by-step explanation:
set up an equation
42w=432
divided both sides by 42
W=10.2857142857
to rounded it to nearest tenth it will be 10.3
to check your answer multiply 10.3 by 42 it will be 432
check check
Answer:
18 ≤ w ≤ 24
Step-by-step explanation:
A = l * w
A ≥ 432 sq ft.
l = 42 - w
432 ≤ (42 - w) (w)
432 ≤ -w² + 42w
w² - 42w ≥ 432
Substitute values for w
w = 18
w = 24
Mrs. Mobley can jog 3 miles in 27 minutes. How many miles can she jog in 81 minutes?
Answer:
9 miles
Step-by-step explanation:
You need to get 27 minutes to 81 minutes so you multiply 27 by 3, and that is 81, so you simply multiply 3 by 3 and get 9! Hope this helps! ;)
(27 x 3) = 81
(3 x3) = 9

A cylinder has a base with a radius of 7 cm and a volume of 615.44 cm3. Use 3.14 for π . Write and solve an equation to find the height of the cylinder.
Answer:
The height is 4 cm
Step-by-step explanation:
V = (pie) x radius² x height
615.44 cm³ = (3.14) x 7² x h
h = 615.44 cm³/(3.14 x 49)
h = 615.44 cm³/153.86
h = 4 cm²
Charlotte and Riley walked 6/10 of a mile to school one day, and then after school they walked 3/8 of a mile to the store. From the store back home was another 2/5 of a mile. How far did the girls walk in all?
Answer: The girls walked [tex]1\dfrac38[/tex] miles.
Step-by-step explanation:
Given: Distance from home to school = [tex]\dfrac{6}{10}[/tex] mile
Distance from school to store = [tex]\dfrac38[/tex] mile
Distance from store to home = [tex]\dfrac25[/tex] miles
Total distance = [tex]\dfrac6{10}+\dfrac38+\dfrac25[/tex]
= [tex]\dfrac{6\times4+3\times5+2\times8}{40}[/tex] [L.C.M.(10,8,5)=40]
= [tex]\dfrac{24+15+16}{40}[/tex]
= [tex]\dfrac{55}{40}[/tex]
= [tex]\dfrac{11}{8}=1\dfrac38[/tex] miles
Hence, The girls walked [tex]1\dfrac38[/tex] miles.

Given the series 2+ 6 + 18+
*
use an appropriate formula to find S12.
Please put full solution.
Answer: Samsung Galaxy S12
Answer:
S₁₂ = 531440
Step-by-step explanation:
There is a common ratio between consecutive terms, that is
r = 6 ÷ 2 = 18 ÷ 6 = 3
This indicates the sequence is geometric with sum to n terms
[tex]S_{n}[/tex] = [tex]\frac{a(r^n-1)}{r-1}[/tex] ( r ≠ 1 )
where a is the first term and r the common ratio
Here a = 2 and r = 3 , then
S₁₂ = [tex]\frac{2(3^{12}-1) }{3-1}[/tex]
= [tex]\frac{2(531441-1)}{2}[/tex]
= 531441 - 1
= 531440
Figure ABCD is a trapezoid. Find
the value of x.
3x+3
B
13
4x+2
A
D
X = ?
Answer:
x = 3
Step-by-step explanation:
The midsegment is half the sum of the parallel bases, that is
[tex]\frac{1}{2}[/tex] (3x + 3 + 4x + 2) = 13
[tex]\frac{1}{2}[/tex] (7x + 5) = 13 ( multiply both sides by 2 )
7x + 5 = 26 ( subtract 5 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3

Step-by-step explanation:
[tex]x^\frac{1}{y}=\sqrt[y]{x}[/tex]
So:
[tex]\sqrt{\frac{4}{25}}=\frac{2}{5}[/tex] because
[tex](\frac{x}{y})^z=\frac{x^z}{y^z}[/tex]

When the door was left open, 36 pigeons flew the coop. If this was 40 percent of all the pigeons, how many pigeons were there originally?
Answer: 90
Step-by-step explanation:
40 % = 0.40. X = number of pigeons. 0.4x =36
X = 36/0.4 = 90
Solve for n.
39 = n − –12
n =
Answer:
Two negative make a positive so this equation is basically 39 = n + 12 so you need to subtract 12 from each side. This makes it n = 27

Anna received a gift card for $25 to an art store. The table shows the cost of the items.
Item Cost ($)
Bottle of Paint: 2.75
Brush: 1.09
Canvas: 7.99
Easel: 18.99
Palette: 4.50
She bought a canvas, two brushes, and three bottles of paint.
Which addition equation can be used to determine how much more money x Anna still has to spend?
A)
7.99 + (1.09) + (2.75) + x = 25
B)
7.99 + 3(1.09) + 2(2.75) + x = 25
C)
7.99 + 2(1.09) + 3(2.75) + x = 25
D)
7.99 + 2(1.09) + 3(2.75) + 25 = x
Answer:
7.99+2(1.09)+3(2.75)+x =25
Step-by-step explanation:
what's given are the prices of the canvas, brushes, and bottles of pain. 7.99 represents the one canvas Anna is buying, 2(1.09) represents the 2 brushes, and 3(2.75) represents the bottle of paints. Now what's left is x and x represents the amount of money left on the gift card. The gift card is $25 in total so that's why at the end of the equation it equals to $25.
