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

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?
Answers
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

Answers
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

A Speedboat increases in speed uniformly from 20m/s to 30m/s for 12.2 s. What is the acceleration of the speedboat?
Answers
Answer:
0.82 m/s^2
Step-by-step explanation:
Given data
initial velocity=20m/s
Final velocity= 30m/s
Time = 12.2s
Applying the formula
a= v-u/t
a= 30-20/12.2
a= 10/12.2
a= 0.819
a=0.82 m/s^2

Sarah bought 18 boxes of 65 pens at $12 a box. She sold 378 of them at 3 for $1.00 and the rest at 4 for $1.00. Find her total profit.
Answers
Answer:
$108
Step-by-step explanation:
1 box = $12
18 boxes = 12×18 = $216
Total = 18×65 = 1170 pens
Cost price, Cp = $216
3 = $1
378 = 378/3 = $126
1170-378= 792 pens remaining
4 = $1
792 = 792/4 = $198
Total selling price, sp = 126+198 = $324
Profit = Sp - Cp = 324 - 216 = $108

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.
Answers
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

Answers
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
