An engineer created a scale drawing of a building using a scale in which 0.25 inch represents 2 feet. The length of the actual building is 250 feet. What is the length in inches of the building in the scale drawing?
Answers
The length of the building in the scale drawing is 31. 25 Inches
How to determine the value
From the information given, we have that;
Scale drawing was used0. 25 inches represents 2 feetThe length of the building is 250 feetThen,
If 0. 25 inches = 2 feet
Then x inches = 250 feet
cross multiply
x × 2 = 0. 25 × 2500
Multiply through, we have;
2x = 62. 5
Make 'x' the subject by dividing both sides by 2
2x/2 = 62. 5/ 2
x = 31. 25 Inches
Thus, the length of the building in the scale drawing is 31. 25 Inches

Two printing presses, working together, can complete a job in 2 hours. If one press
requires 6 hours to do the job alone, how many hours would the second press need to
complete the job alone?
Answers
The number of hours needed for the second press to complete the job is 3 hours.
What is an equation?An equation represents the relationship of two expressions on either side of the sign
Given that together they can complete a job in 2 hours and one takes 6 hours to complete the work alone.
If we let x = amount of time required for the second press to complete the job alone
We can write as:
Second press work = 1/x of the job per hour.
First press work = 1/6 of the job per hour.
Together work = 1/2 of the job per hour.
We can write the equation as:
1/6 + 1/x = 1/2
1/x = 1/2 - 1/6
1/x = (3 - 1)/6
1/x = 2/6
1/x = 1/3
x = 3
Thus number of hours needed for the second press to complete the job is 3 hours.

Answers
The accurately captures a system's gravitational potential energy:
ME = KE + GPE.
What is gravitational potential energy?Gravitational potential energy is the energy that an object possesses or acquires as a result of a change in its position when it is in a gravitational field. In layman's terms, gravitational potential energy is energy that is tied to gravitational force or gravity.
What is the difference between gravitational kinetic energy and potential energy?The energy held in an object due to its height above the ground is known as gravitational potential energy. It is determined by the object's mass, the gravitational acceleration caused by the Earth, and the object's height. Kinetic energy is the energy that an object possesses as a result of its motion.
According to the given data:An object's mechanical energy is equal to the sum of its kinetic energy and potential energy. If ME is mechanical energy and KE is kinetic energy, then PE is its potential energy.
ME = PE + KE
KE = (1/2) mv^2
PE = ME - KE
PE = ME - 1/2(mv²)
PE = ME - 1/2(mv²)
PE = ME - KE
ME = KE + GPE

Answers
The required probability that a patient had surgery and experienced a major improvement 31% and that a patient received nonsurgical treatment 14.5%.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Number of patients who got surgery = 398,
63% of percent said they had a major improvement in their condition,
= 0.63 * 398 ≈ 250
29% among those who received nonsurgical treatment,
= 0.29 * (803 - 398)
= 0.29 * 405
≈ 117
Now,
The probability that a patient had surgery and experienced a major improvement in his or her condition.
= 250 / 803
= 31%
The probability that a patient received nonsurgical treatment and experienced an improvement in his or her condition.
= 117 / 803
= 14.5%
Thus, the required probability is 31% and 14.5%.

Express the interval using inequality notation.

Answers
The inequality notation for the given interval is -∞ < x ≤ -11 and -8 ≤ x < ∞
Disclaimer:
Considering the given interval as (-∞, -11] ∪ [-8, ∞).
Given interval is a union of two intervals.
The first interval denotes the set of all real numbers which are less than or equal to -11.
And the second interval denotes the set of all real numbers which are greater than or equal to -8.
The inequalities can be written as below:
(-∞, -11] ⇒ x ≤ -11 (or) -∞ < x ≤ -11
[-8, ∞) ⇒ x ≥ -8 (or) -8 ≤ x < ∞
And there is a union symbol between these two intervals.
So, x should satisfy both inequalities.
x ≤ -11 and x ≥ -8

What is compound interest?
Compound interest is the interest calculated on the principal amount , which also considers all the accumulated interest of previous periods of deposit or loan.
If P is the principal amount and rate of compound interest is r then after t years of time , the present amount (if the interest is compounded annually) will be = P(1+(r/100))^n
If the interest is compounded quarterly, then the present amount be A
Where A = [tex]P (1+\frac{r/4}{100} )^{4t}[/tex]
Given that Leslie invests in a bank that earns interest quarterly , and account balance after t years is given as 500(1.026)^(4t)
A= [tex]P (1+\frac{r/4}{100} )^{4t} = 500(1.026)^{4t\\[/tex]
Comparing both sides we get P = 500
And 1+(r/400)=1.026
(r/400)=1.026-1
(r/400)=.026
r=400(0.26) = 10.4 %

The sum of two samples is 500 + 175 = 675.

The temperature at noon is 75 degrees. The temperature drops 3 degrees every half hour. What is the temperature at 4 p.m.
Answers
Answer:51 degrees
Step-by-step explanation:
At noon the temperature is 75 degrees
the temperature drops 3 degrees every half hour.
First solve for time elapsed between noon and 4, which is 4 hours.
Next, we can change our rate to be in terms of full hours instead of half hours using the fact that 1 hr = 2 half hours, so the temperature drops 6 degrees every hour.
Four hours have elapsed so multiply 6*4 = 24 degrees and then subtract it from the starting 75
