Answer:
£3591
Step-by-step explanation:
Brian buys a computer for £3600. It depreciates at a rate of 5% per year. How much will it be worth in 2 years? Give your answer to the nearest penny where appropriate.
The formula for Depreciation rate =
P = Po × e^-rt
P = Amount after depreciation
Po = Initial amount = £ 3600
r = depreciation rate = 5% = 0.05
t = time in years = 2
Hence:
P = £3600 × e ^ -0.05 × 2
P =£ 3600 × e-0.0025
P = £ 3591.0112406
Approximately = £3591

if the length of two sides of a triangle are 7 and 10 the length of the third side may be
A. 1
B.3
C.2
D.4
explain
Answer:
D. 4
Step-by-step explanation:
Let's look at all the options first. All of the options are below 7 and 10, hence we can deduce that it is not the hypotenuse. Looking at 7 and 10, we see that 10 is the larger number, and hence we know that 10 is the hypotenuse.
Hence, as the other two sides added up in a triangle must be larger than the hypotenuse, the only available option is 4, since 4 + 7 = 11 > 10.

solve this equation 3.5z – 2.7z = –6
Answer:
z=-7.5
Step-by-step explanation:
Answer:
z = -7.5
Step-by-step explanation:
First you have to simplify the equation:
0.8z = -6
Then you have to isolate the z, and to do so you have to divide both sides by 0.8.
0.8/0.8z = -6/0.8
The answer then comes out to be z = -7.5

The population of bears in a national forest is changing according to the function N(t)=850(1.04)t , where t is the time in years, and N(t) is the number of bears. Which statement explains how the bear population is changing?
Answer:
The statement is that the population increases at a rate of 4% per year
Step-by-step explanation:
The function is given as;
N(t) = 850(1.04)^t
The general equation form for a representation as this is;
P = I(1 + r)^t
Where I is the initial value and P is the present value
r is the rate of increase
t is the time
Thus, we have that;
1 + r = 1.04
r = 1.04-1
r = 0.04
0.04 is same as 4/100 which is same as 4%
So the statement about how the population of bear is changing is that the population increases at a rate of 4% each year

Ben gets 5 more presents than his naughty little sister Gwen this holiday season. If together they receive 21 presents, how many
presents does each kid receive?
9514 1404 393
Answer:
Ben: 13Gwen: 8Step-by-step explanation:
The given relations give rise to two equations:
b = g + 5
b + g = 21
Using the first to substitute for b in the second, we have ...
(g +5) +g = 21
2g = 16 . . . . . . . subtract 5
g = 8 . . . . . . . . . divide by 2
b = 8 +5 = 13
Ben got 13 presents; Gwen got 8.
what is the cost of the item that would make these discount equivalent?
Discount:
30% off $22.50 off
Answer:
$15.75
Step-by-step explanation:

30% = 0.3
Multiply.
22.5 * 0.3 = 6.75
Subtract.
22.5 - 6.75 = 15.75

Consider this equation: 9x - 7 - 3x + 9 = x + 7 + 5x + 9. How many solutions does this equation have?
Step-by-step explanation:
9x - 7 - 3x + 9 = x + 7 + 5x + 9
6x + 2 = 6x + 16
2 = 16
Since 2 = 16 is false, there exist no real solutions for x.
Final Answer: No Solution. The equation would have 0 solutions.
Steps/Explanations:
Hey there! The answer is No Solution because -7 = 7. If 7 = 7, then it would be true and have one solution, which is not the case here.
Step 1: You should cancel [tex]9[/tex] on both sides.
[tex]9x - 7 - 3x = x + 7 + 5x[/tex]
Step 2: Simplify [tex]9x - 7 - 3x[/tex] to [tex]6x - 7[/tex].
[tex]6x - 7 = x + 7 + 5x[/tex]
Step 3: Simplify [tex]x + 7 + 5x[/tex] to [tex]6x + 7[/tex].
[tex]6x - 7 = 6x + 7[/tex]
Step 4: You'll need to cancel [tex]6x[/tex] on both sides.
[tex]- 7 = 7[/tex]
Step 5: Since [tex]-7 = 7[/tex] is false, there would be no solution.
No Solution

What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4y = 6 is an equation.
2x = 4 is an equation.
4x - 6x + 6x = 6 is an equation.
We have,
x - y = 4 _____(1)
4x + y = 1 _____(2)
From (1) we get,
x = 4 + y ____(3)
Putting (3) in (2) we get,
4x + y = 1
4 (4 + y) + y = 1
16 + 4y + y = 1
16 + 5y = 1
Subtract 16 on both sides.
5y = 1 - 16
5y = -15
Divide both sides by 5.
y = -3
Now,
Putting y = -3 in (3) we get,
x = 4 + y
x = 4 - 3
x = 1
Thus,
The value of x and y is 1 and -3.

Use the pencil,plot the point (3 1/2, 2 3/4)
Answer:
The diagram of the plotting point [tex]\left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right)[/tex] is attached below.
Step-by-step explanation:
Given the points
[tex]\left(3\frac{1}{2},\:2\frac{3}{4}\right)[/tex]
as
[tex]3\frac{1}{2}=\frac{7}{2}=3.5[/tex]

A truck driver has to make a delivery at a location that is 230.2 miles away. She drives an average of 55 miles each hour for 3.25 hours. If the truck driver continues at the same speed, will she make it to the location in the next hour?
and how many does she or he have to go
Answer:
The driver will make it to the location in the next hour
Step-by-step explanation:
First, find how many miles they traveled in 3.25 hours, by multiplying 55 by 3.25:
55(3.25)
= 178.75
Then, add 55 to this to see if the driver will make it in the next hour:
178.75 + 55
= 233.75
Since this is greater than 230.2, this means they will make it to the location.
So, the driver will make it to the location in the next hour.
Answer:
Yes
Step-by-step explanation:
Since the truck driver is going at an average speed of 55 miles per hour and has already driven for 3.25 hours that means she has already covered a distance of ...
55 * 3.25 = 178.75 miles
If she continues at the same speed and travels for one more hour that means that she would cover another 55 miles which would put her at a total distance of ...
178.75 + 55 = 233.75 miles
Therefore, the answer would be Yes she would arrive at her location. ;)

your
answer to the nearest cent.
Step-by-step explanation:
Let P be price after t year . From the formula of compounding
P = 9 (1.015)^t
Taking log to the base e on both sides
ln P = ln 9 + t ln 1.015
= (2.197 + .0149t )
P = e^{(2.197+.0149t)}

A gum tree reached a height of 150 ft in 15 years. Cathy and Darla write different equations to find the yearly average growth g of the tree. Cathy writes 15g = 150. Darla writes 150/15 = g. Do these equations have the same solution? Explain.
Answer:
Yes, they have the same answer because because 150/15 = 10 and in the equation 15g = 150, you have to solve it by dividing 150 by 15 which gets 10. Therefor, they are the same.
Step-by-step explanation:
Answer: They have the same solution.
Step-by-step explanation: 15g=150 has an answer of 10 ft. (divide 150 by 15 to get g alone.) 150/15=g has an answer of 10 as well. (Simplify to find g.)
