The price of a computer increase from £631 to £776. 13. The percentage change is 81.3%
As per the given data:
Old value of computer is £631
New value of computer is £776. 13
Percentage Change: Percentage Change is the difference coming after subtracting the old value from the new value and then divide by the old value and the final answer will be multiplied by 100.
The phrase percent change says the difference in the percent of the earlier and present quantity.
Percentage change formula is
Percentage Change [tex]=\frac{{New Value - Old Value} }{{Old Value}} \times 100[/tex]
If the result is positive, then it is an increase.
If the result is negative, then it is a decrease.
[tex]=\frac{631}{776.13} \times 100[/tex]
= 0.813 × 100
= 81.3%
Therefore the increase in percentage is 81.3%

radius of a cone with a volume of 100.48 yds3 and a height of 6 yds
Answer:
r = 4
Step-by-step explanation:
Volume of a cone:
V = πr²(h/3)
Given:
V = 100.48
h = 6
π = 3.14
Work:
V = πr²(h/3)
100.48 = r²(3.14)(6/3)
100.48 = r²(3.14)(2)
100.48 = r²6.28
r² = 100.48/6.28
r² = 16

A tourist standing on the New York City coast sees the Statue of Liberty, which is 305 feet tall. She must tilt her head 9 degrees upwards to look at its head. How far away is she from the base of the statue? Round your answer to the nearest whole foot.
Given:
Height of the Statue of Liberty = 305 feet
Angle of elevation = 9 degrees
To find:
The between the tourist and the Statue of Liberty.
Solution:
Using the given information, draw a figure as shown below.
In a right triangle,
[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]
In the triangle ABC,
[tex]\tan 9^\circ=\dfrac{305}{x}[/tex]
[tex]x=\dfrac{305}{\tan 9^\circ}[/tex]
[tex]x=1925.6942[/tex]
[tex]x\approx 1926[/tex]
Therefore, the tourist is standing 1926 feet from the Statue of Liberty.

1900 is deposited into a savings account. Interest is compounded annually. After 1 year, the value of the account is 1957. After 2 years, the value of the account is 2015.71. This scenario can be represented by an exponential function of the form f(x)=1900(b)^2 , where is the amount in the savings account, and x is time in years. What is the value of b?
Answer:
1.03
Step-by-step explanation:
2015.71 = 1900(b)^2
44.896659 = 43.588989 * b
44.896659/ 43.588989 = b
1.0300000 = b
Recall ; for an exponential distribution :
b In the equation = 1 + r ; where, r = rate
b = 1 + r
1.0300000 = 1 + r
r = 1.0300000 - 1
r = 0.03
Hence, the value of b in the equation is 1.03

Jack and charlie each deposit $17,250 into accounts that earn 6% interest for 6.5 years. Jacks account earns annual compound interest. Who will earn more interest after 6 years, and how much more interest will they earn?
From the amounts found using simple and compound interest formulas, we found that Carlie earns more interest than Jack by $1009.45.
What is the difference between simple and compound interests?
Simple interest is based on the principal amount, which is the main distinction between it and compound interest. Contrarily, compound interest is calculated using the principle sum and interest that has been compounded over the course of a period. Simple interest is a predetermined proportion of the principal amount borrowed or lent that is paid or received over a set period of time. Borrowers are required to pay interest on interest in addition to principal since compound interest accrues and is added to the accrued interest from prior periods.
The complete question is given below.
Given,
The principal amount deposited by both Jack and Carlie P = $17,250
The rate of interest r = 6% = 0.06
The time period = 6.5
Jack's account earns annual simple interest and Carlie's account earns annual compound interest.
So the amount in each person's account after a time period of t = 6 years.
Jack:
Amount = P(1+rt) = 17250 ( 1 + 0.06*6) = $23,460
Carlie:
number of times compounded in a year n = 1
Amount = [tex]P(1 + \frac{r}{n})^{nt}[/tex] = 17250 ( 1+0.06)⁶ = $24,469.45
Therefore from the amounts found using simple and compound interest formulas, we found that Carlie earns more interest than Jack by $1009.45.

C=
m (Round the answer to the nearest whole number.)
Answer:
c ≈ 40
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{26}{c}[/tex] ( multiply both sides by c )
c × sin40° = 26 ( divide both sides by sin40° )

Answer: 1/14 assuming cards are nut returned back in deck
Step-by-step explanation: first is red P(1. R) = 4/8 = 1/2
Second red P(2. R) = 3/7 and P(3. R) = 2/6 = 1/3.
Multiply probabilities , you get 1/14
Answer:
4/56 simplified is 1/14
Step-by-step explanation:
nCr(8,3) = 56
4 (the number of red cards there are) / 56 = 1/14
The Town Theater receives $4212 by selling 465 tickets to
the opening night of the revue. If the full price of a ticket is $10.00
and discount tickets for students and seniors are $8.00 each, how
many discounted senior/student tickets were sold?
Answer:
219
Step-by-step explanation:
let x be the number of full price tickets and y be student/ senior number , then
x + y = 465 → (1)
10x + 8y = 4212 → (2)
Multiplying (1) by - 10 and adding to (2) will eliminate x
- 10x - 10y = - 4650 → (3)
Add (2) and (3) term by term to eliminate x
0 - 2y = -438
- 2y = - 438 ( divide both sides by - 2 )
y = 219
The number of senior/ student tickets sold was 219

The height x of the equilateral triangle is 7√3 inches.
What is an Equilateral triangle?Equilateral triangles are triangles that have all their sides and angles equal to each other. The three angles are 60 degrees each.
Therefore,
The side length of the equilateral triangle is 14 inches.
Therefore, To find the height of the triangle using the Pythagoras theorem.
c² = a² + b²
14² - 7² = b²
b² = 196 - 49
b² = 147
b = 7√3
Hence, The height x of the equilateral triangle is 7√3 inches.
