Question
What is the slope of the line represented by the equation 2x+5y=15
Solution 1
2x + 5y = 15

Subtract 2x from both sides:
5y = -2x + 15

Divide both sides by 5:
y = -2/5 x + 3

Given that y = mx + b,  where m is the slope.
⇒ Slope = -2/5

Answer: Slope = -2/5
Question
Brett mare a scale drawing of a rectangular room in his house.The actual room is 12 4/5 ft.The scale used to make the drawing was 1/4 in=1ft. What is the length in inches of the room on the drawing?
Solution 1
1/4 in : 1 ft

1 ft  ⇒ 1/4 in

12 4/5 ft ⇒ 1/4 x 12 4/5 =  1/4 x 64/5 = 3 1/5 in

Answer: 3 1/5 in
Question
£600 is put in a bank. after a year the money has increased by 8% how much is now in the bank
Solution 1
Increased = 8% x £600 = 0.08 x 600 = £48

Money in the bank now = £600 + £48 = £648

Answer: £648
Question
For a certain manufacturer, only ⅘ of the items produced are not defective.If 2,000 items are manufactured in a month, how many are not defective?
Solution 1
To find the number of non-defective chips, we simply use this equation:
2,000 * 4/5
8000/5
Now you simply divide:
1600
1600 chips aren't defective
Question
An experienced roofer can work twice as fast as her helper. working together, they can shingle a new section of roof in 4 hours. how long would it take the experienced roofer, working alone, to complete the same job?
Solution 1
For this case, the first thing we must do is define variables.
We have then:
x: amount of time the assistant works
Y: amount of time the experienced person works
We then have the following system of equations:
x + y = 4
y = (1/2) x
Solving the system we have:
x = 8/3
y = 4/3
Answer:

It would take the roofer, working alone, to complete the same job about:

y = 4/3 hours
Question
A random sample of 31 charge sales showed a sample standard deviation of \$50. a 90% confidence interval estimate of the population standard deviation is
Solution 1
The  confidence interval of a standard deviation is given by:

Given a sample size of 31 charge sales, the degree of freedom is 30 and for 90% confidence interval,

Therefore, the 90% confidence interval for the standard deviation is given by

Question
A map has the scale 2 centimeters = 1 kilometer. on a map, the area of a forest preserve is 3.8 square centimeters. what is the area of the actual forest preserve
Solution 1
We know that
the scale is 2 cm/1 km
on a map, the area of a forest preserve is 3.8 cm²
assuming it has a square shape
the length side of the square is
√3.8 cm
so
if 2 cm on a map-----------------> is a 1 km in the actual
√3.8 cm------------------------> x
x=√3.8/2 km

the area of the actual forest preserve is
(
√3.8/2)*(√3.8/2)----> 3.8/4---> 0.95 km²

the answer is
0.95 km²
Question
(a) [5 points] using only the definition, find the laplace transform y (s) of y(t) = e a t where a is a constant. for what values of s does the laplace transform y (s) exist? (b) [10 points] solve, using laplace transforms, the initial value problem: y 00 − 4y 0 + 4y = 3, y(0) = 0, y0 (0) = 1.
Solution 1
Find the Laplace transform y (s) of y (t) = e a t. Here, a is a constant. Which value of s exists for the Laplace transform y (s)? (0) = 0, y 0 (0) = 0, y (0) = 0,
